SUMMARY:

REASON FOR ACQUISITION OF TITLE -

There is an adjacent nickel mine and chrysoprase mine to the north of the area and surface sampling under a prospecting licence revealed a 2100ppm Ni anomaly which, it was hoped, would increase with depth.

REGIONAL GEOLOGY:

GEOCHEMISTRY:

- soil sampling - surface sampling revealed a nickel anomaly of 2100ppm

LOCALISED EXPLORATION/PROSPECTS

DRILLING -

Two 150mm diameter drill holes, approximately 10m apart, were sunk to a depth of 31m and both struck groundwater at approximately 20m (3000gals/hr). The groundwater made drilling complicated and the drilling program was abandoned. One kilogram samples were taken at various depths and analysed for nickel. All samples produced results lower than 0.25% Ni and were considered unsuccessful.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE - The title was relinquished due to the poor results of analyses of samples taken from the drillholes and the problems associated with drilling in the area such as topography and shallow groundwater occurrence.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -To explore for gem quality chrysoprase in lateritic soil horizons.

Summary - Extensive prospecting was performed in order to define the limits of outcrop of chrysoprase and also to determine any relationship between soil type and chrysoprase quality. It was determined that a darker and slightly more translucent stone is associated with reddish, ferruginous soil. A small drive was commenced in 400m southeast of the Hanging Rock area (refer to maps p138 QGMJ March 1964), but was abandoned when no high grade stone was encountered. Further bulldozing was done in the area of ML368 with approximately 30 000m3 of earth moved for a return of 0.01kg of gem quality stone per cubic metre.

Prospecting pits were sunk on outcrops found on the northern slopes of an existing open cut working. Exploratory work has defined the chrysoprase occurrence as three main zones 7-10m wide spaced about 40-50m apart. Drives put in to about 10m from the surface has proved that chrysoprase veins become thinner and paler in colour with depth. Most good quality chrysoprase is located in the upper cappings of ridges in the area of interest.

During the three month period to 2/7/1964 360ha was applied for under Mining Leases 383, 384 and 385. BHP conducted a short survey of the chrysoprase deposits in a search for nickel. Assay results indicated Ni content of 2000-7000 ppm which at the time was deemed to have no economic potential.

A market survey was conducted in order to formulate a marketing policy.

SUMMARY:

An assessment of the chrysoprase deposits at ATP's 238M and 243M in the Marlborough area. An unnamed area being exploited is noted, and its location is 6.5 km NW of the intersection of Develin and Marlborough creeks. ATP 238 is located E of this location, while the ATP 243 location is not given.

The report defines the following about chrysoprase and the prospects -

1) Chrysoprase is a green variety of chalcedonic silica, coloured by the presence of nickel oxides.

2) It occurs along and near crests of hills composed entirely of serpentines.

3) Chrysoprase occurs as lenticular concretionary nodules and as a network of thin veins associated with magnesite. They represent remnants of an ancient plateau of lateritised serpentine.

4) Ultra basic rocks containing chromium and nickel were probably altered to serpentine by a nearby granite. Subsequent leaching and weathering of the magnesium silicates produced magnesite and limonitic iron. The free silica seeped into the watertable and precipitated chalcedonic silica. Nickel in the weathering rocks coloured the silica green.

5) Wider veins up to 22 cm which persist to depth are probably of an intrusive nature.

6) Chrysoprase ranges from rich green, compact, even coloured, usually the thinner concretionary nodules, to more massive, thicker veins with variable colour (green - white), and containing small drusy quartz lined cavities.

7) Concretionary veins and nodules from lateritisation are not likely to persist at depth. Intrusive varieties would persist to further depths (ten's of metre's) although colour does weaken. Wide veins of intrusive origin can be laterally extensive.

8) The nature and grade of chrysoprase was assessed by field observation at ATP 238M. Some material was in situ and quality was variable with some super grades. One occurrence not visited is thought to be superior to those inspected. ATP 243M was not visited but was regarded in a likely area to find chrysoprase.

SUMMARY:

GEOLOGY - See CR 5413 for a summary on the geology of the ATP. A summary of the geology of the Mine Corridor Volcanics which host the Mount Morgan Mine is given in CR 6167.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION - Walmul Copper Company (ATP 279M); and Morgan Mining & Industrial Co. P/L (ATP 302M, 352M, 402M, & 403M).

GEOLOGICAL MAPPING - Most of the ATP was geologically mapped in detail.

GEOCHEMISTRY

- stream sediment sampling - A regional stream sediment survey conducted over several years was carried out to locate areas of anomalous geochemistry. The copper plan shows the obvious area of smelter contamination SW of the Mt Morgan mine; the Bouldercombe contamination; the Dee Range anomalous zone comprising Moongan-Struck Oil-Mt Warner trend; the Fern Hills anomalous area; a broad zone of apparent high background in andesitic rocks of the Dee Volcanics and Pond Formation; the Riverhead-Divide anomalous area which is the most pronounced copper zone in the ATP; small anomalous zones associated with the contact zones in the Galloway Plains Tonalite; high back ground values in the Ayrdrie Andesite; and a discreet anomaly associated with the Mannersley Porphyry copper prospect. The zinc plan shows a similar area of smelter contamination to the copper plan; a trend of anomalous zinc roughly follows the Moongan Rhyolite, and is contiguous across the Station Creek Granodiorite with the Dee Range which is the largest zinc anomaly in the ATP, including the Mt Warner, Mt Alexander, and Fab areas; the Fern Hills anomalous zone occurring as a discrete area; a broad area of anomalous values on the W side of the Eulogie Gabbro, thought to represent high background in the Dee Volcanics; an anomaly in the Upper Don area thought to be associated with the Moongan Rhyolites; and a trend reflecting high background values in mainly sedimentary rocks overlying the Ayrdrie Andesite.

- soil sampling - A major program of ridge and spur soil sampling was carried out along the Dee Range from Mt Alexander to the Ajax Mine. Four zones of anomalous geochemistry were delineated within the acid volcanic rocks of the Moongan Rhyolite, and one anomalous zone apparently relates to intermediate volcanics of the Upper Capella Creek beds. The five zones have been named the Omo, Ajax, Fab, Drive, and Grillo Hill.

GEOPHYSICS

- airborne surveys - Originally an airborne magnetic survey was completed over the area by Geophysical Resources Development Company of Sydney. Magnetic anomalies of variable character were outlined, some of which were followed up on the ground. Later, an airborne electromagnetic, magnetic and radiometric survey was carried out by Geoterrex Ltd. over the major part of the ATP.

LOCALISED EXPLORATION/PROSPECTS

1) Ajax Mine area - 4 km SE of Mt Hopeful television tower.

GEOLOGY - The area is comprised of acid volcanics (aphanitic, porphyritic and fragmental varieties) of the Devonian Moongan Rhyolite sequence, mafic dykes, and a limited development of garnet-epidote skarns. The area lies near the junction of the Fern Hills Fault and an un-named linear lying to the W of it. The mine occurs in a SW dipping sequence of rhyolite to dacitic rocks which are intensely altered in the mineralised area. Small pods of high-grade copper and zinc mineralisation occur in a concordant alteration zone up to 100 m thick. Mineralisation is confined to a shear zone, coincident with an area of sericitic and siliceous alteration localised within a quartz-feldspar porphyry. Along strike to the NW the lode passes into unaltered, pyritic quartz-feldspar porphyry and to the S is covered by alluvium. A small rich pod of massive chalcocite associated with a banded pyritic zinc lode was removed from the mine. Production from the mine for the period 1.7.75 to 30.6.76 was 17.8 g Au, 2661.6 g Ag, and 3.82 t Cu from 49.8 t of ore.

GEOCHEMISTRY - Soil samples were collected from the auger drilling. The results are <2 to 880 ppm Cu, 5 to 1600 ppm Pb, and 15 to 8200 ppm Zn. The best results from the percussion and diamond drilling was 0.71% Cu, 360 g/t Ag, 10% Zn, 1.1% Pb, and 6.0 g/t Au.

GEOPHYSICS - Trans-electromagnetics and self-potential surveys were carried out over the area. One traverse of IP was carried out over the main peak of the trans-EM anomaly N of the old workings. No response of significance was recorded. A ground radioactivity survey was conducted over the area, indicating a distinct potassic radiometric anomaly around the ore-bearing horizon, apparently reflecting sericitic alteration. A broad zone of anomalous potassic radiation also occurs in the SW part of the grid, also apparently reflecting sericitic alteration. An EM survey was carried out and the results revealed a small discrete anomaly associated with the known mineralisation and a number of larger anomalies. Some of the other anomalies are associated with observations of alteration and pyritisation.

DRILLING - Auger drilling was conducted over the grid. A large program of percussion and diamond drilling was carried out in the area. Up to 17 m of mineralisation was intersected in some holes drilled near old workings, but most holes did not intersect significant mineralisation.

2) Arnold's Ridge area

GEOLOGY - The area comprises Mine Corridor rocks with a zone of silicification and ferruginisation.

GEOCHEMISTRY - A low-order, broad zone of anomalous Se and Te has been shown by preliminary reconnaissance to be associated with the zone of silicification and ferruginisation.

DRILLING - A diamond drill hole was put down on the Arnold's Ridge alteration zone to test the IP anomaly and the alteration zone.

3) Baree area - 1 to 2 km N and E of the Mt Morgan Mine, in the NW part of the Mine Corridor.

GEOLOGY - The area is underlain by coarse quartz-feldspar porphyry of the UMP, the Arnold's Ridge Felsite, and the Baree Felsite. Aplite granite bounds the acid volcanics of the Corridor Rocks on the NE. The Corridor rocks are intruded by (early) latites and (late) Permian dykes of andesitic composition.

GEOCHEMISTRY - A discrete zone of copper-zinc anomalism was confirmed in this area; it had been previously reported by C.R.A. Soil sampling was carried out over the area. Copper and zinc values show broad, nearly coincident anomalies which tend to be associated with latite intrusions and also occur within the granite. Se and Te were only sampled in the lower part of the grid. Peak values of 1300 and 150 ppb, respectively, were reproduced over an area of alteration (silicification and ferruginisation) in the Arnold's Ridge Felsite. These results were disappointingly low compared to the rock chip values in the area, which reached peaks of 7000 and 1250 ppb, respectively, in previous years.

4) Belgamba area - occurs in the ranges immediately S of Bouldercombe

GEOLOGY - This area was investigated as the apparent source area for the Dee River alluvial gold deposits. A grid was surveyed to cover a lobe of acid volcanic rocks containing pyritic chert and jasper adjacent to the Struck Oil fault in the area just SW of Bouldercombe. S of the Dee River the rocks are all andesitic (Capella Creek beds) which are apparently nearly flat lying. A series of faults mark the boundaries of the lobes of acid volcanic rocks within the grid. The westernmost lobe consists of fine quartz-feldspar crystal tuff, which contains rare thin jasper beds and is weakly altered, bleached, and silicified. The central lobe is similar but is less altered with no jasper. The southernmost area of acid volcanic rocks consist of quartz-feldspar crystal ash tuff which is more chloritic and somewhat coarser. N of the acid volcanic lobes the rocks are all andesite, andesitic tuff, apparently equivalent to the andesitic tuff S of the Dee River.

GEOCHEMISTRY - Chip samples of the pyritic cherts and jaspers did not return any anomalous base metal values. The area was soil sampled, and copper values are low over the grid, with values in the andesitic rocks in the W slightly higher than values in the acid rocks on the E of the grid. Lead and silver values are uniformly low. Zinc values are slightly higher in the W of the grid but could not be considered anomalous, and the area is low in gold. This indicates that the acid volcanics are not the provenance of the alluvial gold.

GEOPHYSICS - A magnetic and IP survey were carried out. The magnetics revealed no discrete contourable anomalies. The local highs and sharp contrasts appear to relate to the fault zones. The only conclusive trend in the IP survey was low resistivity in alluvium. The centre of the grid shows a comparatively high chargeability, but the implications of this response are uncertain.

5) Bell Top area - this area is 12.8 km SE of Mount Morgan near Nine Mile Creek, and just to the N of Bull Creek.

GEOCHEMISTRY - A grid was set up over this area and geochemical sampling was carried out. The results returned were 8 to 4000 ppm Cu (most are less than 200 ppm Cu), and 0 to 4770 ppm Zn (most are less than 270 ppm Zn). Rock chip sampling was carried out in the area returning 0 to 4770 ppm Zn and 13 to 4000 ppm Cu.

6) Bouldercombe area - 12 km NNE of Mount Morgan.

GEOLOGY - This area occurs over the contact between the Bouldercombe diorite and surrounding metamorphosed intermediate volcanic rocks.

GEOCHEMISTRY - Samples were collected from the auger drilling but most values were not considered significant. Stream sediment and rock chip sampling was carried out, indicating the presence of a strong zinc anomaly with, in certain area, anomalous copper values.

GEOPHYSICS - A magnetic survey was carried out over the area.

DRILLING - Auger drilling was carried out over the area.

7) Bull Creek Grid - This area was previously reported in the final report on ATP 279M.

GEOLOGY - Two quartz diorite batholiths occur in the area. The small one in the W referred to as the Bull Creek quartz diorite, while the one in the E, being an extension of the Mine and Town quartz diorite, is referred to as Town quartz diorite. In between these quartz diorite bodies are volcanic rocks. Disseminated pyrite occurs mainly along the contact of the Town quartz diorite. Copper occurs as malachite and azurite in the cores of quartz diorite and feldspar andesite boulders within a boulder bed adjacent to a granodiorite contact. The pyrite and copper mineralisation is considered to be a hydrothermal deposition. At places, pseudo-gossanous iron-stained rocks occur in outcrop.

GEOCHEMISTRY - Stream sediment sampling in the area returned 15 to 115 ppm Cu. Soil samples were collected over the grid. Copper content in soil was erratic in both range and distribution, and corresponded to the erratic distribution of the copper mineralised boulders noted in different exposures. Follow-up work was confined to 7 broad areas of anomalous copper content in soil. Three of the anomalous areas were over granodiorite, one near a basic dyke and the remainder associated with the mineralised conglomerate sequence.

GEOPHYSICS - This area was covered by a ground magnetic, resistivity, self-potential (SP), and trans- EM surveys, but did not return any results of interest.

8) Champion area - 3 km ENE of the Mount Morgan open pit and includes the Champion, South Champion, Golden Cross, Welcome, Peuts and Retrieve mines which occur within a zone approximately 1300x700 m. Numerous other small pits and workings also occur within the zone.

GEOLOGY - The mines were exploiting auriferous quartz reefs. Total production was small with an estimated maximum of 500 oz. The largest mine, South Champion, has been described as an elongate pipe, and production was approximately 100 tons of ore at 19.2 g/t Au, 4.87% Cu, with significant quantities of molybdenite. ?Hydrothermal breccias occur on some dumps.

GEOCHEMISTRY - Rock chip samples were collected from the country rock.

9) Clanricarde area - 3.3 km NW of the Mount Morgan pit. The area includes the Clanricarde, Midas and Crows Nest Mine. Production to July 1949, was 2000 oz Au (grade approximately 1.4 oz/t), 5.5+t Cu (grade approximately 2.1%), and 146+ oz Ag (grade approximately 0.6 oz/t).

GEOLOGY - The Clanricarde and Midas mines worked a reef 2.5 to 15 cm wide. The reef occurs on a NE-SW striking fault. The reef dips SE at 60-70°. The Crows Nest workings occur to the W, on the Stoney Creek fault and apparently exploited small random reefs. The area was grided and mapped, but no large area of alteration or mineralisation was located.

10) Diggers Dive - These workings include several pits, adits, and shafts near the top of a small peak above Kangaroo Creek, 3.25 km SE of the Queen of Sheba workings.

GEOLOGY - Reconnaissance mapping confirmed a tuff (andesitic), sedimentary sequence, overlain by Pond Formation conglomerate. No significant areas of alteration were seen.

11) Divide area - investigating a low-order stream geochemical anomaly with an associated magnetic low anomaly near headwaters of the Calliope and Don Rivers.

GEOLOGY - The rocks consist of a sequence of andesite, andesitic tuff, and sediments of the (?) Upper Devonian - Lower Carboniferous Riverhead beds which are possibly equivalents of the Dee Volcanics - Pond Formation. The sequence is intruded by dioritic dykes and possibly a small stock.

GEOCHEMISTRY - Ridge and spur soil sampling was carried out, with the low-order copper anomaly apparently derived from a zone of quartz veining within a massive andesite in the Riverhead beds. Two anomalous values from the W appear to relate to a small diorite dyke or intrusion. The low geochemical values do not support the suggestion of mineralisation within the area.

GEOPHYSICS - Reconnaissance ground magnetics revealed a magnetic low in the S of the area. The profile suggests the presence of a granodiorite stock beneath the alluvium.

12) Drive area

GEOLOGY - Mapping revealed a small zone of pyritic and strongly altered rocks surrounded by a broad diffuse zone of weakly pyritic rocks with distinct spotted alteration and hornfelsing. Various weakly gossanous rocks occur within the central pyritic zone.

GEOCHEMISTRY - Soil sampling showed low-order Zn values associated with the gossanous zones. Copper, lead, silver and manganese returned only background values.

13) Eastern Part of Station Creek area (Archer area)

GEOCHEMISTRY - Stream sediment sampling was conducted in the area returning 30 to 80 ppm Zn and 2 to 87 ppm Cu.

GEOPHYSICS - Ground magnetics was carried out over the grid.

DRILLING - 9 shallow auger-diamond holes were drilled in the area.

14) Eulogie Park Gabbro

GEOLOGY - A 60 cm wide titaniferous and vanadiferous magnetite layer within the gabbro was located.

GEOPHYSICS - A ground magnetic traverse was made in parts of the area.

15) Eureka Mine - occurs NW of the Grillo Hill prospect.

GEOCHEMISTRY - Rock chip samples returned high values from weakly pyritic limestone dump material from the adit at Eureka, and from the adit entrance wall.

16) Fab area - approximately 20 km SE of Mount Morgan and occurs along strike from the Ajax Mine.

GEOLOGY - This area occurs within a sequence of rhyolitic tuffs, fragmentals, and associated Fe-Mn cherts. A zone of weakly gossanous, intensely altered rocks occurs over a strike length of 1200 m and a width of 250 to 650 m. Granodiorite outcrops along the N of the grid.

GEOCHEMISTRY - Soil sampling was carried out over the grid, returning 5 to 330 ppm Cu, 5 to 1400 ppm Pb, and 10 to 880 ppm Zn. The material from the percussion and diamond drilling returned best results of 2.05% Zn, 0.13% Cu, and 602 ppm Pb.

GEOPHYSICS - A ground radioactivity survey revealed several zones of potassic radiometric anomalies, all apparently correlating with sericitic alteration zones. Ground magnetics revealed an erratic magnetic pattern which was not any use in selecting drill targets. Several discrete but relatively low-order anomalies were detected by a SP survey. These are apparently related to zones of pyritisation in the rock. A Trans-EM survey was carried out over the area. A magneto-metric resistivity survey was carried out. The results indicate the presence of a conducting horizon from 60 to 150 m wide, running N-S through the prospect, parallel to strike, for a distance of 1700 m. Drilling revealed that the conductive horizon is caused by the pyrite-rich layers. SIROTEM traverses were conducted over the whole grid. A major anomaly which is in the appropriate position to reflect a massive sulphide body was discovered on the NE part of the grid. It is larger and broader than the SIROTEM anomalies in the other areas, and it has associated IP character. Drilling revealed the anomaly to be due to abundant pyrite mineralisation.

DRILLING - Auger drilling was carried out over the grid. Diamond, percussion and diamond/percussion drill holes were put down in the area.

17) Fern Hills area - on the Dee Range, just W of "Fern Hills" homestead, S of Mt Hopeful television tower.

GEOLOGY - In the SW corner of the grided area is a sequence of andesitic tuffs which probably represent the basal part of the Capella Creek beds. These may be unconformable on the predominantly acid volcanic rocks in the rest of the grid. The acid volcanic rocks are a series of ferruginous and cherty ash tuffs, usually siliceous but quite variable. In some places these are well-bedded and contain stratiform pyrite. Some of these bedded rocks contain jasper and manganese, and are considered to be the equivalent of the Bedded Formation of the Moongan Rhyolite sequence in the UNMC and Raspberry Creek area. Beneath these bedded rocks is a sequence of massive andesitic fragmental rocks. Thin section work suggests that the rock is in part a chloritised acid volcanic rock rather than an andesitic rock. The lower part of this unit is fine-grained (lapilli tuff) and contains apparent fragments of sulphides, mainly sphalerite. These sulphides are of the style which could occur in the peripheral environment of a major BMS deposit. Beneath the andesitic fragmental rocks is a sequence of ferruginous ash tuffs and some andesitic fragmentals which apparently represent the lowest part of the stratigraphy in the grid area. Further E, with a very irregular contact, is a variable but mainly massive hornblende andesite rock unit. The irregular nature of this unit is suggestive either of an intrusive rock or an unconformably overlying, E-dipping sequence. Within the hornblende andesite are several prominent occurrences of altered, sericitised, and pyritic intrusive rocks which were mapped as "ferruginous ash tuff". These units in places appear to be tuffaceous owing to an apparent fragmental texture, but in other places show characteristic dyke-like patterns. An apparent structural break, marked by changes of lithology along strike, crosses the grid in a NE trend. The break is complex, apparently consisting of several faults and an andesitic dyke. In the NW of the grid is a major unit of weakly foliated, siliceous chloritic fragmental rock. This unit has no clear correlative with the section S of the structural break, although it may be equivalent to the "cherty ash tuff" unit. Beneath this unit is a complex andesitic tuff-ferruginous ash tuff-fragmental rhyolite unit. The "ferruginous ash tuff" may represent an intrusive unit such as that enclosed within the hornblende andesite. This unit may be equivalent to the andesitic fragmental tuff in the S of the grid. Beneath this complex unit is a hornfelsed, highly silicified, cherty ash tuff which usually carries significant pyrite.

GEOCHEMISTRY - Soil samples, stream sediment samples, and ridge and spur soil samples were collected. The soil sampling defined a zone of poorly clustered low-order anomalous copper values in the area of the mineralised andesitic fragmental horizon in the S of the grid. A broader zone of low- order anomalous values occurs in the NE end of the grid, mostly associated with the pyritised siliceous rock, but some are in andesite, or the intrusive "ferruginous ash tuff". Lead values show two irregular closed clusters of low-order values centring on the mineralised andesitic tuff unit in the S of the grid. No anomalous lead values are associated with the copper zone in the N. Zinc values tend to repeat those of copper but show a more consistent pattern, with two significant anomalous zones corresponding to the mineralised tuff in the SW and the silicified zone in the NE.

18) Grillo Hill area - 16 km ESE of Mount Morgan.

GEOLOGY - The area consists of an extensive zone of pyritic sericite-clay alteration within a thinly bedded, nearly flat-lying sequence of acid lithic fragmental rocks and cherts. A pyrite-rich horizon from 50 to 100 m thick occurs in a sequence of andesitic to rhyolite tuffs and siltstones in a major anticlinorium along the front of the Dee Range. Two weakly gossanous altered zones occur within the horizon.

GEOCHEMISTRY - Soil sampling was carried out. Copper values show two highs associated with the exposed alteration zone. A low order lobe of copper values appears to be associated with a dolerite intrusive in the N of the grid. Lead values are not associated with the copper, but occur in a discrete zone in the SW part of the grid. Zinc values are spread widely, occurring both over the lead anomaly and the copper anomaly, excepting for a discrete "hole" in the centre of the NW anomaly, which is coincident with that copper high.

GEOPHYSICS - An IP survey was carried, out returning a complex pattern of resistivity highs and lows over the alteration zone.

19) Gunpowder Creek area - near the headwaters of the Don River which returned weakly anomalous stream sediment values.

GEOLOGY - A small dioritic stock intrudes rocks of the Lower Carboniferous Pond Formation.

GEOCHEMISTRY - Ridge and spur soil sampling was carried out, but the only values of significance were copper values to 3500 ppm associated with gossanous quartz veins within the stock. The small size of the zone precludes any economic significance for the area.

20) Hamilton Creek area - 5 km S of Mount Morgan

GEOLOGY - A large, intensely altered and pyritic zone occurs in rocks of the (?) Capella Creek beds immediately S of a block of the Mine Corridor rocks. The (?) Capella Creek beds in the area consist predominantly of intermediate lithic tuff, feldspar porphyry, and minor limestone. The Corridor rocks in the area consist mainly of fine quartz-feldspar porphyry. The Capella Creek beds in the area are gently folded into a S-plunging anticline in the area of the alteration zone. The anticlinal structure is more or less concentric with the occurrence of the Corridor rocks, which appear to be a faulted-in block. The alteration zone consists mainly of a clay mineral with lesser amounts of calcite, sericite, and chlorite, with pyrite up to about 8% in places. The alteration crosses the stratigraphy. Several relatively minor faults cut across the area. The Dee Volcanics occurs on the W side of the grid.

GEOCHEMISTRY - Detailed stream sediment sampling was carried out, returning 35 to 255 ppm Cu, 10 to 150 ppm Pb, and 25 to 562 ppm Zn. Soil geochemistry was carried out over the area of interest on the grid, and returned 15 to 550 ppm Pb, 26 to 230 ppm Zn, 8 to 420 ppm Cu. Rock chip sampling was done over specific areas, returning 7 to 7150 ppm Zn, 25 to 1800 ppm Cu, and 0.02 to 0.19% W. Assays of the material from the drilling returned 5 to 9100 ppm Cu, 5 to 1100 ppm Zn, 0 to 70 ppm Pb (with one high of 300 ppm Pb), <20 to 20 ppm W, and traces to 2 ppm Ag. Most of these values are not significant with respect to mineralisation, tending to reflect variations in rock geochemical background.

GEOPHYSICS - Ground magnetics, trans-EM, and self-potential surveys were carried out over the area, but no significant results were returned.

DRILLING - One auger-diamond drill hole and 8 shallow diamond drill holes were drilled in the area. Later a percussion-diamond drill hole was put down more or less on the axis of the S-plunging anticline.

21) Head of Capella Creek area - approximately 19 km E of the confluence of the Dee River and Fletcher Creek in the central part of the ATP.

GEOLOGY - The area is underlain by sandstone, conglomerate, and lavas, intruded by micro-diorite dykes.

GEOCHEMISTRY - This area showed a geochemical anomaly in the regional stream sediment survey.

GEOPHYSICS - Ground magnetics and self-potential surveys were carried out over the grid.

22) Head of the Dee area - located on the main dividing range between the Dee River and Station Creek.

GEOCHEMISTRY - Detailed Stream sediment sampling was done over the grid area and the adjacent areas.

GEOPHYSICS - A magnetic and self-potential survey have been carried out over the area.

23) Horse Creek area

GEOCHEMISTRY - Initially, rock chip and soil samples were collected and indicated the presence of some highly anomalous Hg, and Se/Te values. Also three grids (A, B, & C) were surveyed over the three anomalous areas, and soil samples were collected from the grids. Results from grids showed weak to pronounced anomalies in Hg, Te, Se, Zn, and Cu. Analysis of the core from the drilling confirmed the presence of the anomalous elements located in the soil sampling, but values are generally somewhat lower. In one hole, the weathered part of the core showed enrichment in Hg, Zn and Cu, while only low values were received from the fresh rock. This indicates possible remobilisation of values in the weathering profile.

GEOPHYSICS - Three lines of reconnaissance self-potential were carried out, but due to dry ground conditions the results are inconclusive. A detailed IP survey was conducted. Two anomalies were indicated, one near the Dee Bowling Club, and the other W of Grid A. Interpretation of the results indicate that the second IP anomaly is probably due to surface phenomena like percolating ground water in swampy terrain.

DRILLING - 2 diamond drill hole were completed to test the anomaly in Grid A. The alteration zone indicated on the surface was shown at depth to be similar to some parts of the alteration pipe in the Mt Morgan Mine, but is of lesser intensity.

24) Horse Creek South area

GEOLOGY - The area is a lobe of quartz-feldspar porphyry of the Mine Corridor surrounded by the Mount Morgan Tonalite. Within the lobe is a poorly define zone of silicified and ferruginised rock similar to the alteration zones at Horse Creek. At the S end of the lobe is a small (?)fault block of Dee Volcanics.

GEOCHEMISTRY - Geochemical results show a low-order anomaly of Zn and Cu but their significance is no yet known.

25) Kangaroo Creek area - SW part of the Prior Park grazing farm.

GEOLOGY - The rocks in the grid occupy a N-S elongate embayment of limestone, acid lithic and feldspathic tuff and acid feldspar porphyry of the Mid-Devonian Capella Creek beds, within the Stockyard Creek Granodiorite. The rocks have been hornfelsed into crystalline limestone, garnetiferous limestone, garnet (-epidote) skarn, calc-silicate hornfels, and hornfelsed limey tuff.

GEOCHEMISTRY - Analysis of the soil samples from the auger drilling returned 12 to 170 ppm Cu, 40 to 190 ppm (mostly 70 to 90 ppm) Zn, and 28 to 100 ppm Pb. Rock chip samples were also collected, returning 520 ppm to 0.09% Cu. However, further rock chip sampling did not repeat any anomalous results.

GEOPHYSICS - Detailed trans-electromagnetic and self-potential surveys were carried out over the area.

DRILLING - 43 auger holes were drilled and samples were collected from the soil profile for geochemistry and bed-rock chip for subsurface geological interpretation.

26) King Solomon - These workings are situated 37 km SE of the Mount Morgan pit, and the workings consist of several shafts, pits and an adit.

GEOLOGY - The country rocks are andesitic tuffs. No large zones of alteration or quartz veining were noted. A large (100 m diameter) diorite intrusive occurs to the E of the prospect.

27) Lancefield area - on Manton Creek, approximately 2 km upstream from Lancefield Homestead.

GEOLOGY - A complex of quartz diorite, granodiorite, and gabbro intrudes tuffaceous sandstone and conglomerate of the Permian Youlambie Conglomerate.

GEOCHEMISTRY - Ridge and spur soil samples were collected, but the only values of any significance were the copper values in the gabbro which were of the order of 100 to 200 ppm Cu.

28) Lennox area (Middle Creek) - 8 km SE of Mt Morgan

GEOCHEMISTRY - Soil samples were collected from the area.

29) Limestone Creek area - the area occurs near Walmount (about 2 km SW of the Struck Oil Porphyry Stock) and was located by a small magnetic anomaly.

GEOCHEMISTRY - Samples from the ?auger drilling were analysed. The results ranged from 15 to 190 ppm Cu. Soil sampling was carried out, returning 25 to 390 ppm Pb, 20 to 1500 ppm Hg, 25 to 2250 ppm Zn, and 5 to 900 ppm Cu. Follow-up ridge and spur soil sampling was carried out over several small areas of interest, returning 5 to 500 ppm Cu, 10 to 205 ppm Zn, 15 to 205 ppm Pb. Analysis of core from one of the diamond drill holes returned 20 to 4100 ppm Cu, 10 to 227 ppm Pb, 10 to 26,875 ppm Zn, and traces of gold.

GEOPHYSICS - Ground magnetic, self-potential and trans-EM surveys were conducted in the area.

DRILLING - A line of ?auger holes were drilled in the area. 2 auger-diamond drill holes, and 5 diamond drill holes, were drilled in the area. Irregular narrow zones of epidote alteration with associated pyrite, sphalerite, chalcopyrite and calcite are common at some levels in the drill holes.

30) Limestone Creek area 2 - approximately 2 km SW of the Struck Oil area.

GEOCHEMISTRY - The results from the ridge and spur soil samples and samples of stream sediments in the area are under study.

DRILLING - A small program of ridge and spur hand augering was carried out in this area.

31) Linda Gully area - 1 km N of Mount Morgan Mine. Several shafts and adits had been put down in the area in about 1900.

GEOLOGY - The rocks in the area consist of coarse quartz-feldspar porphyry of the Upper Mine Porphyries. These contain two poddy horizons of limestone which have been skarnified in places by contact with small latite intrusions in the area. The small magnetite skarn zone show high values of Se, Te, Cu, and Zn.

GEOCHEMISTRY - Samples of the skarn returned values of 1.5% Cu and 2.0 g/t Au. Analysis of core from the diamond drilling returned no anomalous results.

GEOPHYSICS - The area was read with a magnetometer. The drill core was also examined with the magnetometer and the latite bodies were found responsible for the magnetic anomaly.

DRILLING - 3 diamond drill holes were put down in the area.

32) Mannersley area - just SW of the Calliope River on the N edge of the Galloway Plains.

GEOLOGY - The prospect is underlain by a granodiorite porphyry stock which lies just to the N of the major Galloway Plains Tonalite. Mineralisation is mainly confined to a smaller biotite granodiorite stock within the granodiorite porphyry. The stock is bounded on the W by a sedimentary/volcanic sequence which is Carboniferous in age. Two narrow beds of magnetite have been located on the S position of the Mt Grim Ridge.

GEOCHEMISTRY - Soil samples were collected from over the whole grid by auger drilling. The highest copper value was 2120 ppm in the S of the grid, and molybdenum values ranged between detection limit to a peak of 32 ppm Mo. Ridge and spur soil sampling and detailed stream sediment sampling were used to indicate the extent of the Cu/Mo anomaly. C-zone soil sampling was then used to cover the anomaly. This sampling defined three anomalous areas of copper. The N and the central Cu-anomaly lie within the area of outcrop of the central biotite granodiorite stock. The S Cu-anomaly zone lies adjacent to, and trends roughly parallel to, the granodiorite - granodiorite porphyry contact. Molybdenum values define an area similar to that of the central Cu-anomaly, and Zn values define a number of slightly anomalous areas. Samples of the core were analysed, returning 370 ppm to 0.37% Cu, and 2 to 520 ppm Mo.

GEOPHYSICS - An IP survey was carried out over the geochemically anomalous area and indicated a strong anomaly just S of the quartz diorite stock, associated with high Cu in the soil. A magnetic survey was also carried out, but no response of significance was recorded.

DRILLING - Auger drilling was undertaken to obtain soil samples. 3 diamond drill holes were completed over the area testing geochemical and geophysical anomalies.

33) Marble Mountain Grid - occurs in the SE corner of the ATP, immediately N of Marble Mountain.

GEOLOGY - This grid is a small area over gossanous material in sediments belonging to the Mount Holly beds adjacent to an intrusive granodiorite. The gossan which appears to be hematitic with usually poorly developed boxworks, is associated with limestones and other limey sediments where they occur in contact with a medium grained intrusive biotite granodiorite. Garnetiferous limestone, gossans and the occasional quartz veins are the most obvious of the contact effects produced by the granite.

GEOCHEMISTRY - Both stream sediment and soil sampling failed to detect any anomalous zinc and copper values. Chip samples of the gossan returned traces of gold, trace to 0.8 dwt/ton Ag, 70 to 130 ppm Pb, 225 to 305 ppm Zn, 230 to 750 ppm Cu, 0 to 12 ppm Mo, and 0.11 to 0.33% S.

GEOPHYSICS - A ground magnetic survey failed to produce conclusive results.

34) McKnight's area - this is the NW extension of the UNMC area

GEOLOGY - The geology is the same in the UNMC area.

GEOCHEMISTRY - Soil sampling was carried out over the new extension of the grid. The anomalous values of copper recorded in the UNMC grid in the banded cherty tuff die out at the edge of the grid. High background values of copper occur in andesitic rocks. Lead values show no trends. Zinc values show that the UNMC anomaly dies out rapidly along strike in the Footwall Sequence. However, the zones of high background in the dyke and the andesites to the S and N which were revealed in the copper values are also reproduced in the zinc values. Silver shows no significant trends, and manganese values show elevated background in andesitic rocks and dykes. These results suggest that the favourable geological environment within the UNMC grid loses its geochemical character to the W and is no longer of interest in this direction.

35) Mine Anticline area - this area is in the Mt Morgan mine leases S of the opencut mine.

GEOCHEMISTRY - Samples of core from the early drilling were assayed, returning trace to 0.30 gr/m tn Au of gold, and trace to 0.42% Cu. Assaying core from the "Upper Banded Mine Sequence" indicate anomalous base metals within the jaspers, with values increases with proximity to the Mt Morgan Mine.

DRILLING - 5 diamond drill holes were completed in this area. The holes reached indicated the presence of weak mineralisation, but grades were too low to be of significance. The holes generally confirmed the concept of a monoclinal fold plunging shallowly SE.

36) Mine Corridor North - this large area also includes the smaller Linda Gully area, Arnold's Ridge area, Upper Mundic area and Baree Area. These small areas will be dealt with separately.

GEOCHEMISTRY - Rock chip samples were collected from outcrops. Most of the values are low- order, with only rare values showing anomalous character, defining four zones of anomalous values.

GEOPHYSICS - A major Gradient Array IP survey was carried out over most of the grid area. The only feature of any significance was a very large anomaly extending N of the Horse Paddock Dump in a SE direction to the Walterhall area. The anomaly is broad in the NW but sharp in the SE. The peak of the anomaly is within the Mount Morgan Tonalite. A bulldozer uncovered an old water pipe which was the source of the sharp peak of the IP anomaly. Drilling indicates that the broad part of anomaly was caused by anomalous amounts of fine pyrite.

DRILLING - 2 diamond drill holes were drilled in the area, but only low values of chalcopyrite and sphalerite were encountered. Percussion drilling was carried out to investigate the IP anomaly.

37) Mine Corridor South area - the area extending from the section where the Dee River crosses the Mine Corridor to Horse Creek.

GEOLOGY - The area is mainly underlain by coarse quartz-feldspar porphyry of the UMP. The sequence is thought to dip shallowly E. Minor zones of hematite-magnetite ?skarn occur in the N and S parts of the area. Two small zones of weak alteration were found, but these are too small to be economically significant. A zone of "fine acid" volcanic rocks (possibly fine quartz-feldspar porphyry) occurs on the S end of the area. Late Permian dykes cut across the area.

GEOCHEMISTRY - Rock chip samples were collected over the area, and assayed for Cu, Zn, Au, Hg, Se, and Te. The results show the presence of a few scattered, isolated anomalies. Material from the diamond drilling returned 30 to 995 ppm Cu, 5 to 180 ppm Pb, 70 to 1400 ppm Zn, and trace to 0.6 g/t Ag. A 20 cm thick skarn zone with about 20% pyrite yielded 2680 ppm Cu, 2.4 g/t Ag, and 396 ppm Zn. A second pyritic skarn zone, 1 m thick yielded 2.0 g/t Ag, 1180 ppm Cu, and 348 ppm Zn. No other significant values were recorded.

GEOPHYSICS - A trial gravimetric survey was carried out.

DRILLING - Two holes were put down by the Queensland Depart of Mines under 50% subsidy arrangement with Geopeko. The first hole was put down in the N part of the area, but no significant mineralisation was found. The second hole was located 500 m SE of the first hole. The equivalent of the BMS in a much diminished form was intersected in the second hole. As a host for a Mount Morgan-type orebody, its potential would appear to be considerably diminished. Two skarn zones with minor mineralisation occurred in the hole.

38) Moonmera Porphyry Copper Prospect - four areas were looked at in detail, these are the Moonmera Triangle, Moonmera Quarry Breccia zone, and No.2 Shaft area.

(A) Moonmera Triangle area (central part of the prospect) -

GEOLOGY - The Triangle area shows two zones of intense alteration associated with an irregular intrusion of quartz monzonite porphyry into a major batholith of quartz diorite-granodiorite (Bouldercombe Complex).

GEOCHEMISTRY - Soil sampling was carried out, returning anomalous values in copper and molybdenum over the alteration zone in the No.3 shaft area, and a weaker zone above the DDH MM 13, put down by North Broken Hill. Analysis of material from the drilling returned maximum values of 2.95% Cu with negligible Mo.

DRILLING - Three short diamond, and 6 percussion drill holes were put down in the area.

(B) Moonmera Quarry Breccia Zone

GEOLOGY - Brecciation and alteration occurs in a complex of biotite quartz diorite and quartz diorite porphyry which has been invaded by a mass of quartz monzonite porphyry in the S. Coarse blebs of chalcopyrite occur in the N of the brecciated and altered zone in the creek bed in an old quarry which was mined at about the turn of the century. Coarse boxworks occur in the altered rock on the slopes on the S of the area. The unusual coarse and sparse nature of the mineralisation makes the prospect very difficult to evaluate by any conventional means.

GEOCHEMISTRY - Soil sampling was carried out in the area. The zone of alteration yielded relatively uniform values between about 0.1% to 0.2% Cu, dropping off sharply in unaltered rocks to slightly high background values. Molybdenum soil values are generally very low except in the S part of the alteration zone, where they reached values of 60 ppm. Analysis of core from the drilling returned peak values of 0.7% and 0.8% Cu, but averaged for the length of the holes, the best results were 0.1% Cu. Three bulk samples were taken from an area of exposed fresh rock in the old quarry. Results of the three samples were 0.23%, 0.97% and 0.52% Cu.

DRILLING - 6 short diamond drill holes were completed.

GEOLOGY - The mineralisation occurs in a wedge-shaped block of intensely altered quartz diorite porphyry ? breccia associated with an intrusive tuffisite (andesite breccia) pipe. After the results of the drilling, the zone is considered too small to warrant exploitation.

GEOCHEMISTRY - Material from the percussion drilling was assayed with a maximum value of 1.59% Cu. The diamond drill hole returned no mineralisation of significance.

DRILLING - The zone was tested with fifteen shallow percussion drill holes, one of the holes was continued by diamond drilling.

39) Moonmera - Lariat

GEOLOGY - A small breccia zone occurs on the approximate centre of a radial dyke swarm SE of the Moonmera porphyry copper prospect. It is probably part of the Moonmera mineralisation system.

GEOCHEMISTRY - Ridge and spur soil sampling was carried out over a small breccia zone to the SW of the Moonmera Prospect. Anomalous values were revealed over the breccia, but the small size of the zone did not warrant further work.

40) Morganite and Great North Lode areas - 2.5 and 3 km N of Mt Morgan mine respectively.

GEOLOGY - Both areas are windows of Corridor rocks emerging beneath the Jurassic Razorback beds. Both show zones of silicification and pyritisation in the acid volcanic rocks (fine quartz-feldspar porphyries) of the corridor. Small shafts, pits, and adits were put down in these alteration zones.

GEOCHEMISTRY - Rock chip samples were collected from the area. The copper values show discrete anomalous zones in both areas. The values for zinc, lead, and gold were only back ground values. Soil sampling was also carried out, returning 5 to 470 ppm Cu, 10 to 30 ppm Pb, 2 to 160 ppm Zn, and 9 to 90 ppb Au. The adit in the Great North Lode was chip-sampled along its length and analysed, returning 45 to 860 ppm Cu, 10 to 30 ppm Pb, 10 to 460 ppm Zn, and <0.1 ppm Au.

41) Mount Bennett area - 10 km W of Mount Larcom township and includes the old Mount Bennett Gold Mine.

GEOLOGY - The area has poor outcrop, and the geological interpretation is based on weathered surface rock fragments. The area includes retextured sediments and volcanic agglomerates. Feldspar porphyries are evident in the W. In the area of the old gold workings, fairly wide quartz reefs striking approximately E-W are found intruding the sediments.

GEOCHEMISTRY - Stream sediment samples were collected from the E part of the grid, but results were negative. Core samples from the drilling were analysed, returning 50 to 310 ppm Cu, 10 to 155 ppm Pb, 35 to 190 ppm Zn, <2 to 115 ppm Mo, <0.1 to 0.2 ppm Au, and <50 to 1900 ppb Te

GEOPHYSICS - Magnetometer and trans-EM surveys were conducted over the Mount Bennett grid. Part of the grid was also covered by an IP survey, but results were not conclusive.

DRILLING - A total of 5 short diamond drill holes were completed. They were mostly designed to test various geophysical anomalies. Minor pyrite was present in two of the holes.

42) Mount Cedric area - 1 km N of Mt Cedric on the Alma Range, investigating a low-order geochemical anomaly with an associated magnetic high.

GEOLOGY - A small stock of biotite quartz diorite intrudes interbedded tuffs and sediments of the (?) Middle Devonian Capella Creek beds.

GEOCHEMISTRY - Ridge and spur soil sampling was carried out over the area, but the results were generally low.

GEOPHYSICS - Reconnaissance magnetic traversing was carried out, and the magnetic anomaly was shown to be due to magnetic material within the tuffaceous rock.

43) Mount Dick area - extension of the grid between Raspberry Creek and UNMC.

GEOLOGY - The geology is an extrapolation of that of the UNMC area, and the zone of alteration and silicification within the Bedded Formation can be traced from the Springs Creek drilling area. At this point the zone is intensely silicified and contains abundant jasper, reminiscent of the "Siliceous Chimney" at the Mount Chalmers mine. The zone terminates abruptly and in its place is a manganiferous siltstone similar to the Manganese Marker horizon of UNMC but lower in the sequence, small gossans are also associated with this unit. The Bedded Formation in this area is thinner than UNMC or Raspberry Creek.

GEOPHYSICS - Two SIROTEM traverses were carried out in the area. Both traverses displayed a clearly developed anomaly which could indicate massive sulphide mineralisation.

44) Mount Grim area

GEOLOGY - A sequence of acid lithic tuffs with a fossiliferous limestone bed is intruded by the Mannersley Complex. The fossils have been identified as Lower Carboniferous. The area contains outcrops of magnetite-garnet-calcite skarn.

GEOCHEMISTRY - Ridge and spur soil sampling was carried out, but the only significant anomalous values received were in a zone within the main intrusive and a small zone on the margin. The low- order and small size of these anomalies does not warrant further work.

GEOPHYSICS - Reconnaissance ground magnetics was carried out over the area, and the results indicate that there is no potential for significant tonnages of ore.

45) Mount Hopeful area - Adjacent to the Upper Raspberry Creek area.

GEOLOGY - Mapping in this area shows that the Bedded Formation is continuous over the edge of the Dee Range and down the N side. Dips are shallow to the W. Hanging-wall quartz-feldspar crystal lithic tuffs with variations, and also Andesite Sequence (? unconformable) occur to the S.

GEOCHEMISTRY - Soil sampling was carried out. Copper defined a weak zone trending along the top of the range corresponding with a manganiferous siltstone horizon. Lead values shows the same zone as copper, and zinc values further define the trend at the top of the range, and show that it extends down the E slope of the range as marginally anomalous values.

46) Mount Morgan Mine

GEOLOGY - The Mount Morgan Mine is hosted in a belt of siliceous and porphyritic rocks. They occur in a narrow belt bounded on either side by the Mount Morgan Tonalite, extending for several kilometres N and S of the Mine. For purposes of localised exploration, the Mine Corridor has been divided into the following areas; Mount Morgan Mine, Mine Corridor North, Mine Anticline, Mine Corridor South, Horse Creek, and Horse Creek South. Mapping of the mine area generally confirmed the classification of the Mt Morgan orebody as a "volcanogenic massive sulphide" deposit. The mine consists of a pipe- like massive pyritic copper-gold deposit underlain by a disseminated "stringer zone" of siliceous ore. The orebody occurs within a large siliceous alteration pipe which transgresses the acid volcanic rocks of the Middle Devonian (?) Capella Creek beds. Owing to faulting and tilting of the stratigraphic sequence, the lower "stringer zone" is now at the same level as the upper "massive zone". Relocation of the Slide Fault and tilting of the sequence from a NE dip to near horizontal returns the mine to its original position.

GEOPHYSICS - A ground magnetic survey was conducted over the mine. Trans-EM surveys were carried out over the mine area and corridor rocks to the N and S of the mine.

DRILLING - Exploration diamond drilling for stratigraphic and structural purposes was carried out over the mine area. About 30 holes were drilled. A program of percussion drilling was later carried out to test a small stratiform zone of Cu-Zn mineralisation in the NE corner of the open cut.

47) Mount Warner area - 19.3 km SE of Mount Morgan

GEOLOGY - The area includes a sequence of variously retextured sediments and quartz porphyries. Limestone lenses, jaspers and cherts are evident in the NW and are intruded by a large feldspar porphyry dyke, with intrusion breccias developed along the margins of the dyke. In a stream a small pyrite and chalcopyrite outcrop in a narrow band is apparently conformable with the sedimentary bedding. 60 m further W of this outcrop occurs a narrow elongated zone of gossan approximately 12 m x 150 m, also parallel to the bedding. The type of gossan indicates a probability of comparable mineralisation to that exposed in the creek.

GEOCHEMISTRY - Stream sediment sampling under ATP 403M revealed a spot high of copper and a pronounced zone of high zinc values which covers an area of approximately 2.6 km². Ridge and spur soil and rock geochemical sampling was carried out over the area. This work confirmed the broad zone of zinc highs with occasional associated copper highs. Assay of the core returned 20 to 2250 ppm Cu, 50 to 51,178 ppm Zn (most less than 1000 ppm Zn), 10 to 85 ppm Pb, and traces of gold and silver.

GEOPHYSICS - Magnetic, resistivity, electromagnetic, and self-potential surveys have been carried out.

DRILLING - Two diamond drill holes were completed in this area.

48) Mount Usher - 12 km ENE of the Mount Morgan open pit. Approximately 30,000 oz gold was produced from the workings which include the Mount Usher, Caledonian, Anglo Saxon, and Victor workings.

GEOLOGY - The workings exploited two narrow sub-parallel reefs. Mapping at Mt Usher revealed two steeply dipping reefs separated by 8 m of barren material (? carbonate). In the New Golden Cave workings, a thin (10 cm) quartz reef occurs. Minor quartz/sulphide filled joints/shears also occur. Pyritisation is commonly associated with many of the deposits and an intensely pyritised zone over 2 km in length has been mapped closely associated with the Victor mine along the inferred Mt Usher fault system.

GEOCHEMISTRY - Wall samples from Mt Usher and the New Golden Cave returned no significant gold values except in some of the thin reefs.

49) Omo Prospect

GEOLOGY - This prospect consists of a very small gossanous zone within a large intense alteration zone W of and contiguous with the Ajax alteration zone

GEOCHEMISTRY - The core from the diamond drilling was analysed, and the best results were 0.44% Zn, and 0.15% Cu.

DRILLING - A diamond drill hole was put down underneath the gossanous zone to test whether the zone had any depth extent. The hole reached intersected two zones of minor pyrite-sphalerite-chalcopyrite mineralisation.

50) Paddy's Gorge Creek area - 2 km W of Mt Morgan.

GEOCHEMISTRY - Stream sediment, rock chip, and ridge and spur soil sampling was carried out over the area.

51) Peacock Shaft area - High-grade mineralisation was reported from the old Peacock Shaft put down in about 1900. The shaft is presently covered by the Horse Paddock dump.

DRILLING - A diamond drill hole was put down to intersect the mineralisation recorded in the old shaft. The hole intersected mainly quartz-feldspar porphyry with some latite. No significant mineralisation was intersected. The reported ore may still be present, but is probably on either side of the latite intrusion.

52) Penumbra area - Just W of the Fern Hills prospect, at the other side of the Dee Range.

GEOLOGY - (The geology given here covers the Shadow area as well as the Penumbra area). The rock sequence belongs to the Lower to Middle Devonian Capella Creek beds. It consists of massive acid lithic tuffs, and fine acid volcanic rocks interbedded with fine grained intermediate volcanics and banded fine acid rocks. Lenses of recrystallised limestone 100 to 800 m long occur in the upper part of the sequence. In the Shadow area, these rocks are intruded by a quartz-feldspar porphyry unit and a massive hornblende andesite unit. The sequence has been folded into an assymetrical anticline (Penumbra Anticline) which can be traced from Fern Hills to Penumbra.

GEOCHEMISTRY - Soil samples were collected from the area. The majority of copper values are less then 200 ppm Cu, and Zn values less than 300 ppm. Soil samples collected from the auger drilling returned no values of significance. The analysis of the core from the drilling returned values of less than 650 ppm Cu, and <130 ppm Zn.

GEOPHYSICS - Trans-electromagnetic and resistivity surveys were carried out over the area.

DRILLING - One diamond drill hole was drilled over the spot high of the best trans-EM anomaly. Subsequently three auger holes were drilled on the second trans-EM anomaly.

53) Pearce's Prospect - 8 km E of Mt Morgan at the head of Station Creek.

GEOLOGY - The area can readily be divided into 4 geologically distinct, structurally separated zones. (a) Calcareous intermediate lithic tuffs - This sequence outcrops in the NE corner of the grid. (b) The Shear Zone - This is a 100 m wide zone of limestone, quartz-feldspar porphyry, fine acid volcanic, chert, and feldspar porphyry. (c) Massive Acid Sequence correlated with the Moongan Rhyolite to the east of the Shear Zone. (d) A Banded Sequence to the west of the Shear Zone.

GEOCHEMISTRY - Soil sampling was carried out over the area, returning only very low anomalies, indicating that the area is of little interest economically.

GEOPHYSICS - Trans-electromagnetics and self-potential surveys were carried out over the area.

54) Poison Creek area - occurs 19 km NE of Mount Morgan

GEOLOGY - In all cases where bedrock samples were obtained, the rock chips were of biotite- granodiorite overlain in much of the area by thick river gravel.

GEOCHEMISTRY - The drill cuttings returned only low Cu and Fe values.

GEOPHYSICS - A ground magnetic survey was conducted over the area.

DRILLING - Rotary drilling was carried out in the area.

55) Quarry Creek area

GEOLOGY - A large part of the area is covered by a usually massive, intermediate to basic rock, though tuffaceous and fine banded varieties do occur. This unit appears to be flat lying or gently folded. Three other units also occur in the area; a foliated aphanitic andesite unit; a feldspar porphyry lithic tuff; and an intermediate lithic tuff/tuffaceous shale unit which constitutes the bulk of the sequence in the W part of the grid. Basic and acid dykes also occur in the area.

GEOCHEMISTRY - A soil survey was carried out, but no anomalous values were returned.

56) Queen of Sheba - These workings occur approximately 1.8 km S of the King Solomon workings.

GEOLOGY - Reconnaissance mapping confirms an anticlinal axis trending N-S through Grasstree Yards. The anticline is indicated by dips on massive andesitic tuffs, and ferruginous "jasper" beds near the axis. Two small (50 m diameter) diorite bodies occur near the axis. Quartz "reefs" occur in pits, shafts etc. along a zone about 600 m long. Outcrop and float on top of a hill indicated a larger zone of alteration and quartz veining, and this area was costeaned, revealing alteration, quartz veining and a deeply weathered basic dyke.

GEOCHEMISTRY - The costeans were sampled and revealed only low gold values except for some quartz veins in the southern costean.

57) Raspberry Creek area - This area is 14 km SE of Mount Morgan, and is the along-strike extension of the Upper Nine Mile Creek area.

GEOLOGY - A thick, strike extensive pyritic zone containing sub-gossanous rocks occurs stratigraphically above a sequence of quartz-chlorite fragmentals and below a manganiferous sedimentary horizon. A discrete zone of gossanous, leached, siliceous material occurs on the E end of the grid.

GEOCHEMISTRY - Soil sampling revealed a large, broad copper anomaly with values over 50 ppm occupying two distinct zones within a large area above 25 ppm Cu. The N zone sits just above the bottom contact of the pyritic acid volcanics with the underlying Mt Dick Fragmentals, but below the continuous, well bedded manganese siltstone horizon. The S anomaly overlies the manganese siltstone. Lead values, like copper, form a broad, long, irregular anomalous zone. There are two distinct lead highs over 40 ppm Pb. The N one is displaced relative to the copper high by 400 m to the E. The other significant lead high is an elongate irregular zone, up to 400 m wide, and it is open ended. Zinc values are low throughout the grided area.

GEOPHYSICS - SIROTEM traverses were done over the area. A broad, high-order anomaly was detected, but no detailed work has been done owing to the lack of available time. A pronounced circular anomaly which is thought to represent 5x107 t of sulphide mineralisation was also detected.

DRILLING - The circular anomaly was investigated by percussion-diamond drilling. Virtually no sulphides are present compared to the altered and pyritised rocks on the surface in this area. The reason for the lack of sulphides in the drill hole compared to the surface is not known.

58) Riverhead area - Upper reaches of the Calliope River, W of Gladstone.

GEOLOGY - In the N part of the grid, the sequence consists of strongly outcropping acid volcanic rocks overlain by poorly outcropping sedimentary and pyroclastic rocks. To the S of the grid, siltstone, fine sandstone, and greywacke comprise the greater part of the sequence. This largely sedimentary unit is intruded by three small biotite-quartz diorite stocks. A variety of dykes exist in the area, most are later in age than the stocks and are of little interest.

GEOCHEMISTRY - Soil samples were collected from the area. The best results for copper were from the quartz-biotite diorite stocks (values mostly ranged from 1000 to 2000 ppm Cu, with a maximum of 8500 ppm). A granodiorite porphyry dyke to the N and NW of the W stock returned values of up to 7200 ppm Cu. Only 5 anomalous values of Mo were recorded, with the highest values of 100 and 200 ppm Mo associated with the zone of high copper values over the W stock. Analysis of core samples ranged from 95 ppm to 0.23% Cu, 5 to 40 ppm Mo, and <0.1 ppm Au.

GEOPHYSICS - Ground magnetic and trans-electromagnetic surveys were conducted over the area.

DRILLING - A trial was made to drill through the alluvials with 4 auger holes drilled. Three short holes were drilled through the alluvial boulder beds W of the grid to test the country rock for possible underlying porphyry-copper style mineralisation. A combination of auger, hammer, and diamond drilling was used. Six diamond drill holes were completed in the area. Some mineralisation was intersected.

59) Shadow area - 1.5 km S of the Penumbra prospect on the Dee Range.

GEOCHEMISTRY - Ridge and spur sampling was carried out, returning 5 to 300 ppm Cu, 15 to 80 ppm Pb, and 45 to 435 ppm Zn.

GEOPHYSICS - Reconnaissance trans-electromagnetic work was carried out.

60) Southern Part of the Plumtree area

GEOCHEMISTRY - Detailed sediment sampling has been done over the area.

GEOPHYSICS - A magnetic survey was carried out over this area.

61) St.Mary's Falls area - 10 km E of Mount Morgan

GEOCHEMISTRY - Detailed stream sediment, rock chip, and ridge and spur soil sampling was carried out in the area.

62) Stockyard Creek area - SE part of ATP 508M.

GEOCHEMISTRY - The C-zone samples from the auger drilling were assayed returning 4 to 118 ppm Zn, 0.75 to 7.6% Fe, and 14 to 311 ppm Cu.

GEOPHYSICS - Magnetic and self-potential surveys were carried out over the area

DRILLING - Auger drilling was carried out over the area.

63) Struck Oil area - 8 km E of Mount Morgan

GEOLOGY - The area generally lacks outcrop, and the geological information was based on interpretation of weathered fragments brought up during subsequent hand augering. Conglomerates and interbedded siltstones and sandstones persist in the E portion of the grid, whilst quartz porphyries and granodiorite porphyry are evident in the W and N portions. Dykes of microdiorite texture and composition frequently intrude these sediments and intrusives.

GEOCHEMISTRY - Initial drainage sediment geochemical sampling and follow-up ridge and spur soil sampling in the Struck Oil area was carried out under ATP 403M. Results from soil samples from the auger drilling revealed a broad zone of copper highs, frequently associated with molybdenum, corresponding closely to the geological contact between the sediments and intrusive determined from mapping of fragments. Rock chip samples were collected from gossans, skarns, dykes and alteration zones. The gossans and skarns returned anomalous Cu and W values; epidote alteration zones commonly were anomalous in Cu; while dykes failed to return any significant metal values. Hand augering soil sampling was conducted over skarn and alteration zones, but only one returned significantly anomalous values Assay of core samples from the diamond drilling returned 0.009 to 1.240% Cu, 0 to 0.3 dwt Au, traces of Ag, and 0 to 2900 ppm Mo (most <300 ppm Mo).

GEOPHYSICS - Ground magnetic, electromagnetic, resistivity, gravity, trans electromagnetic, and self- potential surveys were conducted over the area. The magnetics confirmed the presence of a low in the area, but appears to be too wide and shallow to be of interest from an exploration point of view.

DRILLING - Auger drilling was carried out to collect soil samples. 13 diamond drill hole were drilled to test the geochemical anomaly.

64) Talban Hill Breccia Pipe - This area is 1.5 km S-SE of the Mt Morgan Mine, and is also known as the Light of Day Mine.

GEOLOGY - The Talban Hill Breccia Pipe is an intensely altered breccia zone occurring on the contact of the Mine Corridor rocks with the Mount Morgan Tonalite at the N end of the Mine Corridor South. Breccia fragments within the pipe consist of fine siliceous Mine Corridor rocks and tonalite, all of which are set in a fine altered matrix which is often highly pyritic. Some of the breccia fragments of rhyolitic rock are also pyritic.

GEOCHEMISTRY - Analysis of material from the drilling yielded 0 to 0.15 g/t Au, 24 to 184 ppm Cu, 24 to 66 ppm Pb, 18 to 132 ppm Zn, and 0 to 5 ppm Mo. These values are not significant suggesting that the earlier sampling of underground workings may have been false. On the other hand, the percussion holes were not very deep and most of the recorded values from the old workings were from lower down. Material from a diamond drill hole put down by North Broken Hill in 1969 was split and assayed. It returned no gold values of significance over the whole of the intersection.

DRILLING - 3 percussion holes were drilled.

65) Thomases Gossan area - 7 km N of the Mount Morgan Mine. Limited tonnages of high-grade ore were extracted from small workings in the area.

GEOCHEMISTRY - Assays of soil sampling showed a zone of contamination below the old workings and an apparent zone of dispersion up into the Razorback beds. A slightly anomalous zone of copper appears to follow the unconformity. A spot high of coper in the Razorback beds may represent contamination. Zinc values show a concentration along the base of the Razorback beds similar to that shown for copper. A low-order anomaly occurs in the Razorback beds corresponding with a copper anomaly.

DRILLING - Hand augering to collect soil samples was carried out. 14 percussion drill holes were put down to see whether any small pods of high-grade ore could be recovered, but without success.

66) Trotters Creek area - 7 km S of Mount Morgan. Located from the airborne geophysical survey.

GEOCHEMISTRY - 6 rock chip samples were collected.

GEOPHYSICS - Reconnaissance Trans-electromagnetic work was carried out.

67) Upper Don area - at the head of the Don River.

GEOLOGY - The lowermost unit in the sequence is the quart-feldspar crystal-lithic tuff cropping out along the river. This is overlain immediately to the E by quartz porphyry lithic tuff which is similar but coarser grained. Both of these units contain localised ovoid alteration zones which are silicified and altered. Overlying these units to the E is a complex zone of interbedded fine acid volcanic rocks and acid lithic tuffs. These rocks vary in their proportion and appear to represent the equivalent horizon to the Banded Sequence at Mount Morgan. The entire sequence is dipping moderately to the NE. On the W side of the area is a complex sequence of andesite, andesitic tuff, sandstone, siltstone, and shale which is unconformable on the acid volcanic sequence. This is thought to be part of the Dee Volcanics. To the S this unconformable sequence is repeated across a major fault.

GEOCHEMISTRY - Ridge and spur soil samples were collected, and the results indicate a complex zone of anomalous values in the S part of the area. The grid was soil sampled by a hand auger. Copper shows a broad zone of high values on the S end of the grid which apparently reflects high background geochemistry in the basic to andesitic suite of volcanics. N of the fault, the acid volcanics have only low background copper values, and several discrete anomalous zones occur associated with gossanous zones. Lead generally shows very low background values. A broad zone of low-order anomaly occurs approximately coincident with the copper zone in the central part of the grid, but does not occur over the E copper zone. This anomaly is open to the N. Zinc shows a major broad anomaly associated with copper, and the anomaly is open to the N.

GEOPHYSICS - A reconnaissance SP survey indicated a broad zone, low-order anomaly roughly coincident with the geochemistry. A ground radiation survey was carried out over part of the grid. This showed a broad weak potassic radiometric anomaly stratigraphically above the gossanous zones. The uranium channel showed an unusual linear anomaly for which no explanation has been found. A SP survey was also carried out over part of the grid, and showed a broad low associated with the topographic high and also with the gossanous areas.

DRILLING - Hand augering was carried out to obtain soil samples.

68) Upper Manton Creek area - the headwaters of Manton Creek immediately N of the Upper Don River catchment area. Low order anomalous copper and zinc geochemical values were recorded from the early stream sediment survey.

GEOLOGY - The oldest rocks in the area are the acid volcanic rocks which extend from the Upper Don River area. On the divide between the Don River and Manton Creek catchment areas are variable acid lithic tuffs, and fine (?) dacite flows. These rocks extend W, under outliers of sandstone thought to be part of the Dee Volcanics, to the central part of the area around a horse-shoe bend in Manton Creek. The rocks in the central part of the area are mainly variations of the siliceous lithic tuff characterised by chloritic shards (? fiamme) and a fine ashy or siliceous matrix. On the W side of the horseshoe is a prominent cherty very fine-grained ash tuff with rare feldspar phenocrysts and minor chloritic fragments. This rock has an unusual siliceous spotted alteration pattern. In the N part of the area is a zone of "acid lithic tuff" which is not as well indurated as the remaining acid volcanic rocks and weathers more deeply. On the SW side of the area a sequence of andesitic rocks and sediments lies unconformably above the acid sequence. These are thought to belong to the Dee Volcanics of Pond Formation. The rocks consist of a basal unit of medium to coarse-grained green volcaniclastic well- bedded sandstone, ranging up to lithic lapilli tuff. These are overlain by coarser lithic tuffs. Finer- grained sedimentary rocks including siltstone, chert, and fine sandstone also occur in this upper sequence. Fossils occur in some of these units but these have not yet been dated. Fossils from slightly higher in the sequence W of the Upper Don area yielded Early Carboniferous ages. A large area of alteration occurs in the N part of the area W of the horseshoe bend. It consists of highly silicified zones in the acid volcanic rocks which carry pyrite or gossan up to 15% but average somewhat less. Minor occurrences of secondary copper mineralisation were found in the rocks of the (?) Dee Volcanics, and one occurrence of native copper was found in a small dyke on the SE end of the area.

DRILLING - hand augering was used to collect soil samples.

69) Upper Mundic area

GEOLOGY - This area occurs north of a small embayment of the Mt Morgan Tonalite into the Mine Corridor.

GEOCHEMISTRY - Low-order geochemical values have been returned from this area, but the significance has not yet been assessed. Analysis of cuttings from the percussion drilling, and core from the diamond drilling returned 10 to 780 ppm Cu, 4 to 60 ppm Pb, 36 to 1180 ppm Zn, traces of gold, and trace to 1.0 g/t Ag.

DRILLING - Two deep percussion holes were put down in an area of alteration, pyritisation and anomalous Se-Te. No significant sulphides were intersected except for the disseminated pyrite. One of the percussion holes was extended by diamond drilling.

70) Upper Nine Mile Creek area (UNMC) - 11 km ESE of Mount Morgan in the headwaters of Nine Mile Creek. The area was partly investigated as the Mount Warner area. Exploration is focused on a major copper-zinc geochemical anomaly found previously.

GEOLOGY - The rocks are the part of the Capella Creek beds that are locally known as the Moongan Rhyolite. The lowermost rock unit on the grid is the Footwall Tuffs, comprising coarse fragmental and agglomeratic rocks with no significant fine-grained sediments. These rocks occur along the Dee Range for a strike length of over 7 km. Overlying the Footwall Tuffs is the "Bedded Formation", which consists of an interbedded sequence of layered rhyolitic ash tuff, crystal tuff, jasper-chert-chloritic siltstone, and lithic lapilli tuffs. Some stratiform sulphides have been found in drill core. At the top of the Bedded Formation is a distinctive unit of manganiferous hematitic siltstone and jasper about 10 m thick. This unit is called the "Manganese Marker" and is traceable for over 10 km in the area. Overlying the Manganese Marker is a sequence of massive and banded fragmental and lithic tuffs of rhyodacite composition. A sill of magnetic andesitic feldspar porphyry intrudes the sequence. From the initial work done on the prospect, two areas of economic significance were located. The first is a lens of barite-rich (up to 22% BaSO4) agglomerate within the Bedded Formation. The second, in Springs Creek, is an exposure of sheared fragmentals, cleaved chloritic siltstones, baritic gossan, and cryptocrystalline pyritic cherts sitting above the Footwall Tuffs. Old shallow diggings are concentrated on the sub-outcrops of the gossan.

GEOCHEMISTRY - Rock chip sampling of the units exposed revealed the presence of high levels of copper, lead, and zinc in the Manganese Marker, Bedded Formation, and altered Footwall Tuffs. The gossans from the northern area returned averages of 898 ppm Cu, 817 ppm Pb, 1827 ppm Zn, and 1369 ppm Mn. Analysis of the material from the hand augering has revealed 5 geochemical anomalies. Anomaly 1 is situated on the barite zone which overlies banded pyritic sediments. Anomalies 2 & 3 occur on the S part of the grid in the Springs Creek area, and are open to the S. Anomaly 4 is within the Bedded Formation, and Anomaly 5 is within altered Footwall Tuffs. Material from the drilling program returned intersections with values up to 20% Zn, 3.3% Cu, 0.5% Pb, 125.5 g/t Ag, and 0.51 g/t Au.

GEOPHYSICS - The area was covered by a ground magnetic survey. A SP survey identified an anomaly in the Footwall Tuffs. An IP survey revealed four narrow linear, strike conformable anomalies (Anomaly A, B, C, and D). Anomaly A is in Springs Creek, Anomaly B is in the Footwall Tuffs, Anomaly C is adjacent to the SP anomaly, and Anomaly D is located in the Hanging Wall Tuffs. A resistivity survey revealed highs on the Footwall and Hanging Wall Tuff units. A resistivity low forms a cross-cutting trend, and is adjacent to IP Anomaly A. A TURAM (EM) survey identified small anomalies forming a definite linear zone trending parallel to strike within the Bedded Formation. One SIROTEM traverse was completed in the area. Initial single loop traverses suggested a small anomaly, but later displaced loop traverse yielded no anomaly. The data for the UNMC area are not complete due to lack of time available for the survey.

DRILLING - Hand auger drilling was carried out to collect B-horizon soil samples. A large program of percussion and diamond drilling was carried out in the area investigating geochemical and geophysical anomalies. One diamond drill hole was also put down by the Queensland Department of Mines. Some holes intersected significant pyrite, sphalerite, chalcopyrite mineralisation, but most encountered only minor mineralisation.

71) Upper Raspberry Creek area - approximately 20 km SE of Mount Morgan. This area is the along- strike extension of the Upper Nine Mile Creek and Raspberry Creek areas.

GEOLOGY - Units outcropping are a strike continuation of the Bedded Formation. Stratigraphically, the lowermost unit of the grid is a pyritic rhyolite tuff which is overlain by a sub-gossanous sericitic and limonitic zone. Overlying the pyritic tuffs is a sequence of manganiferous horizons consisting of siltstone, jasper, chert and interbedded pyritic and non-pyritic tuff and breccia. The uppermost rhyolitic lithic tuff of this group is immediately overlain by a geochemically anomalous magnetic, sulphide-rich manganiferous chert-siltstone unit known locally as the Yarrawonga bed. Rhyolitic tuff, lava breccia and ignimbrite overlies the Yarrawonga bed, and are in turn overlain by a jasper horizon which marks the uppermost limit of the sequence of rocks considered equivalent to the Bedded Formation at UNMC. The Bedded Formation at Upper Raspberry Creek is overlain by chloritic, calcareous and fossiliferous fragmental tuff, agglomerate, and intermediate ash tuff. Dolerite and feldspar porphyry sills have intruded the sequence and some transcurrent faulting is evident.

GEOCHEMISTRY - B-horizon soil samples were collected and assayed. Copper defined two large anomalies. The W anomaly is open to the W and occurs near the stratigraphic top of the Bedded Formation. The E anomaly is open to the NE and overlies the Yarrawonga bed. Lead values define an irregular, broad zone of anomalous values which extends over much of the N part of the Upper Raspberry Creek grid. It contains two significant zones. The W zone is open to the E and lies above a manganiferous sedimentary horizon. The E zone is open to the N, and is coincident with the copper anomaly over the Yarrawonga bed. Zinc values defined a weak, elongate anomaly. Several small zinc anomalies correlate with the lead and copper anomalous zone over the Yarrowonga bed. High silver is noted to correlate with the anomalous Cu, Pb, and Zn over the Yarrawonga bed. A later soil sampling survey indicated that the altered Footwall Volcanics and manganiferous beds in the Bedded Formation return weakly anomalous values of copper, lead, and zinc, but no pronounced anomalies are present.

GEOPHYSICS - Two SIROTEM traverses were completed, but detected only low order anomalies.

72) West of Fernvale area - this area is about 56.5 km SE of Mount Morgan on the W flank of the Dee Range.

GEOLOGY - The area has poor outcrop, and the geological interpretation is based on weathered surface rock fragments. The area consists mainly of quartz and fine sediments cut by a set of feldspar porphyry dykes and by a later hornblende microdiorite dyke. In the SW is an outcrop of dacite.

GEOCHEMISTRY - A restricted zone of relatively high zinc values cover and area of approximately 2.6 km².

GEOPHYSICS - A magnetic survey was conducted over the area.

73) Youlambie - this area is following up a INPUT - EM anomaly in the Youlambie Conglomerate.

GEOCHEMISTRY - Ridge and spur soil sampling was carried out over the area, but the values returned are considered insignificant.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE - The ATP was relinquished in May 1984. Two areas of interest, the Upper Don and Fern Hills, have been retained under Lease Application by the Joint Venture partners. The ATP was surrendered conditionally on the granting of a new authority (ATP 3953) incorporating the required sub-blocks.

SUMMARY:

GEOLOGY -

REGIONAL - In the SE corner of the ATP (Langmorn Creek area) the Lower to lower Middle Devonian Mt Holly beds (limestones, limey rocks, sandstones, greywackes and fragmentary rocks) are intruded by a granodiorite of unknown age. In general the granodiorite is strongly weathered and tends to form topographic depressions whereas the sediments usually form pronounced strike ridges. Contact effects are most pronounced where limestones and associated limey sediments lie in close proximity to the granodiorite. The effects range through evidence of re-crystallisation to development of calcareous silicate rocks which are sometimes garnetiferous. The predominantly sedimentary sequence in the area generally strikes NW to N with steep dips both to the E and W. Two small outcrops of flat lying, Tertiary, olivine basalt forming residual cappings were noted. Minor mineralisation has been noted in the area. Malachite was observed both in a narrow shear and associated with aplite intruding country rock between Stockyard and Oaky Creeks, whilst a gossan occurrence is reported under Marble Mountain Grid.

The Struck Oil area lies approximately 1.6 km E of the Mount Morgan Granite-trondhjemite mass within a sequence of quartz porphyry and Devonian conglomerate, sandstone, and siltstone. These sediments generally strike NNW-SSE and can be traced along strike to the Mount Warner area. Numerous limestone lenses containing corals and bryozoans occur in the sequence.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION - Walmul Copper Company (ATP 279M); and Morgan Mining & Industrial Co. P/L (ATP 302M, 352M, 402M, & 403M).

GEOLOGICAL MAPPING - Geological mapping was started in the SE portion of the ATP, and in the Struck Oil area E of Mount Morgan

GEOCHEMISTRY

- stream sediment sampling - A stream sediment survey was conducted to cover areas not previously sampled during investigations of previous Authorities to Prospect 302M, 352M, 402M, and 403M. Close interval sampling was employed in the Plumtree, Mount Hopeful and Langmorn areas. Result so far have disclosed a number of spot high copper values, occasionally with anomalous zinc content, and a large area in the Mount Hopeful area containing some 17 sample sites in which the zinc content exceeded 300 ppm, up to a maximum of 770 ppm. The Plumtree area is characterised by a background distribution of copper and zinc values.

GEOPHYSICS

- airborne surveys - An airborne magnetic survey was completed over the area by Geophysical Resources Development Company of Sydney. Magnetic anomalies of variable character have been outlined, some of which will require much follow-up work in order to relocated these anomalies on the ground and to study their associated geological environment.

LOCALISED EXPLORATION/PROSPECTS

1) Bull Creek Grid - This area was previously reported in the final report on ATP 279M.

GEOLOGY - Copper mineralisation has been found associated with granitic boulders within a boulder bed adjacent to a granodiorite contact.

GEOPHYSICS - This area was covered by a ground magnetic and a self-potential (SP) survey.

2) Eulogie Park Gabbro

GEOLOGY - A 60 cm wide titaniferous and vanadiferous magnetite layer within the gabbro was located.

GEOPHYSICS - A ground magnetic traverse was made along a line which had been chip sampled during an investigation of the area under ATP 352M. A second line was also traversed parallel to the first line.

3) Struck Oil area - The Struck Oil area lies approximately 1.6 km E of the Mount Morgan Granite- trondhjemite mass.

GEOPHYSICS - Ground magnetic and self-potential surveys were conducted over the area.

DRILLING - Auger drilling was carried out, with the holes drilled to a maximum of 1.8 m where possible. A diamond drill hole was begun to test the geochemical anomaly but was abandoned due to technical problems. A second hole was drilled approximately 8 m from the original, and reached a depth of 75 m.

4) Mount Warner area - 19.3 km SE of Mount Morgan

GEOLOGY - The area includes a sequence of variously retextured sediments and quartz porphyries dipping between 45° and 70° to the W. Limestone lenses, jaspers and cherts are evident in the NW and are intruded by a large feldspar porphyry dyke; intrusion breccias are developed along the margins of the dyke. A small stream pyrite and chalcopyrite outcrop in a narrow band apparently conformable with the sedimentary bedding. 60 m further W of this outcrop occurs a narrow elongated zone of gossan approximately 12 m x 150 m, also parallel to the bedding. The type of gossan indicates a probability of comparable mineralisation to that exposed in the creek.

GEOCHEMISTRY - Stream sediment sampling under ATP 403M revealed a spot high of copper (300 ppm) and a pronounced zone of high zinc values (up to 1770 ppm) which covers an area of approximately 2.6 km². Rock chip samples of the small pyrite and chalcopyrite outcrop returned 4.0% Cu, 2% Zn, 390 ppm Pb, trace gold. Follow-up ridge and spur soil and rock geochemical sampling was carried out over the Mt Warner area. This work confirmed the broad zone of zinc highs with occasional associated copper highs. At this stage these anomalous zinc and copper values have not been directly related to mineralisation as typified by the gossan.

5) Marble Mountain Grid - occurs in the SE corner of the ATP, immediately N of Marble Mountain.

GEOCHEMISTRY - Both stream sediment and soil sampling failed to detect any anomalous zinc and copper values. Chip samples of the gossan returned traces of gold, trace to 0.8 dwt/ton Ag, 0.11 to 0.33% S, 70 to 130 ppm Pb, 225 to 305 ppm Zn, 230 to 750 ppm Cu, and 0 to 12 ppm Mo.

GEOPHYSICS - A ground magnetic survey failed to produce conclusive results.

SUMMARY:

GEOLOGY -

REGIONAL - The Central Creek area is dominated by granite, conglomerate, and feldspar porphyry.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -

GEOLOGY -

REGIONAL - In the Mount Morgan - Hamilton Creek area, the oldest rocks are banded siliceous rocks of the Mine Corridor Complex, which are intruded by quartz porphyry and quartz-feldspar porphyry. The Mine Corridor rocks are overlain by agglomeratic and tuffaceous bedded rocks with a trachy- andesitic composition, belonging to the Dee Volcanics. Both the Dee Volcanics and the Mine Corridor rocks are intruded by granodioritic rocks of the Mount Morgan Igneous Complex.

In rocks in the Raspberry Creek - Mount Warner area belong to a Middle Devonian sequence of volcanoclastic beds (fine crystal tuffs and slightly coarser agglomeratic beds) with a trachy-andesitic to andesitic composition. In places, limestone lenses and cherts are interbedded. The lower part of the sequence consists of rather massive quartz-feldspar porphyry, known regionally as the Moongan rhyolites. Strike and dip measurements indicate the presence of shallow, open folds with a NW-SE direction. The structures are cut off in the W by the E part of the "Town" granite-granodiorite.

In the Bouldercombe - Plumtree area, a gabbroic body is located on the S margin of the Gracemere Granodiorite. The latter intrudes the gabbro, and along the contact zone it has been contaminated to give a diorite. The gabbroic mass exhibits some layering due to differentiation. Two other gabbroic bodies occur, one to the E and one to the W of the main body. The main stock intrudes the axis of an anticline, but there are marked structural and lithological variations across the axis. To the E, well bedded tuff, agglomerate, conglomerate, chert and sandstone occur. These strike about 130° and dip to the E at about 40°. To the W a complexly folded sequence of massive fragmental and volcanic rocks with interbedded quartz-feldspar porphyry and chert occur. Adjacent to the granodiorite a zone of highly metamorphosed calcareous and pelitic sediments are found. This truncates the folding within the stratified rocks of the Dee Volcanics. To the E of the Dee Volcanics are conformably overlain by the limy sediments of the Pond Argillite.

REGIONAL EXPLORATION

GEOLOGICAL MAPPING - Regional mapping was carried out in the area immediately S of Mount Morgan (Hamilton Creek), the area around Raspberry Creek, and Mount Warner.

GEOCHEMISTRY

- stream sediment sampling - The regional stream sediment survey was continued, with samples collected from the S section of Gelobera, parts of Langmorn area, and the N section of Manton.

LOCALISED EXPLORATION/PROSPECTS

SUMMARY:

REGIONAL EXPLORATION

GEOCHEMISTRY

- stream sediment sampling - A further 35 stream sediment samples were collected in the S part of the ATP.

GEOPHYSICS

- airborne surveys - An airborne electromagnetic, magnetic and radiometric survey was carried out by Geoterrex Ltd. over the major part of the ATP.

LOCALISED EXPLORATION/PROSPECTS

1) Mount Morgan Mine

GEOCHEMISTRY - Analysis of core from hole 8-60 returned 0 to 0.6 g/mtr Au, and trace to 1.7% Cu. No ore-grade mineralisation was encountered outside the orebody.

GEOPHYSICS - Trans-EM ground survey was carried out over the mine area and corridor rocks to the N and S of the Mine.

DRILLING - 5 diamond drill holes were completed with a total of approximately 1000 m (4-42, 43, 7- 36, 7-37, and 8-60), and drilling is continuing. Exploration drilling for stratigraphic and structural purposes continued over the Mine Lease south of the open cut. Three holes were drilled for this with a total of 1207 m.

2) Struck Oil area - 8 km E of Mount Morgan

GEOCHEMISTRY - Core from DDH2/11 returned 0.02 to 0.15 ppm Cu, and 0 to 70 ppm Mo. Core from DDH2/12 returned 200 to 9700 ppm Cu (most <1500 ppm Cu), and 0 to 500 ppm Mo (most <200 ppm Mo).

DRILLING - Two diamond drill holes (DDH2/11 and DDH2/12) were drilled to a depth of 348 m and 462.68 m. DDH2/11 was centred over a trans-EM anomaly, and the anomaly was explained by generally high pyrite content in the core. DDH2/12 was drilled to test a geochemical anomaly and the geochemical anomaly was shown to be associated with a skarn horizon.

3) Hamilton Creek area - 5 km S of Mount Morgan

GEOCHEMISTRY - The core from the drilling was split and analysed, but the results are still being analysed.

DRILLING - Six short diamond drill holes with a total of 296.56 m were drilled over the area.

4) Trotters Creek area - 7 km S of Mount Morgan. Located from the airborne geophysical survey.

GEOCHEMISTRY - 6 rock chip samples were collected.

GEOPHYSICS - Reconnaissance Trans-electromagnetic work was carried out.

5) Paddy's Gorge Creek area - 2 km W of Mt Morgan.

GEOCHEMISTRY - Initially, 5 stream sediment samples and 4 rock chip samples were collected. Later, follow-up ridge and spur soil sampling was carried out with 44 samples collected. Results are under study.

6) Limestone Creek (near Walmount) area

GEOCHEMISTRY - Analysis of core from DDH37/1 returned 20 to 4100 ppm Cu, 10 to 227 ppm Pb, 10 to 26,875 ppm Zn, and traces of gold.

DRILLING - DDH37/1 was completed, reaching a depth of 494.13 m; it was designed to test for mineralisation in the axial area of the Walmount Syncline below a Cu/Pb/Zn soil anomaly. The core was logged with the following descriptions; 0-19 m Mineralised sediments - This is a fine-grained, green, highly fractured rock, with the fractures being filled with iron oxides; 19-379.40 m Intermediate Tuffs - Lithic fragments were all andesitic in composition being either felsite (fine grained plagioclase- rich rock) or feldspar porphyry. All grain size variations were present, from <1 mm in ash tuff units, to up to 30 cm in some of the coarser volcanic breccias. Bedding was common within the finer grained ash tuff units, but rare in coarser grained beds; 123.30-141.00 m Quartz-feldspar Porphyry - Diorite porphyry consisting of subhedral quartz and plagioclase phenocrysts up to 2 mm, set in a fine-grained (<0.10 mm), holocrystalline, quartzo-feldspathic matrix with variable chlorite and epidote. This unit is identical in hand specimen to the rhyodacite unit mapped on the surface; 379.40-479.40 m Andesites and Andesitic Tuffs - This is a magnetite-rich sequence of alternating lithic lapilli tuffs and massive andesites. There is little difference between the fragments and the matrix in the tuffs, except that the fragments contain more magnetite; 479.40-494.13 m Tonalite Porphyry - This rock type consists of subhedral quartz and plagioclase phenocrysts up to 4 mm in diameter set in a matrix of micrographic intergrowths between quartz and plagioclase. Chlorite after hornblende (?) and minor epidote are also present. Compositionally this tonalite porphyry relates to the "Town Granite Complex".

Irregular narrow zones of epidote alteration with associated pyrite, sphalerite, chalcopyrite and calcite are common within the intermediate lithic tuff unit. Chloritisation is the common form of alteration within the andesitic lithic tuff unit.

7) Lennox area (Middle Creek) - 8 km SE of Mt Morgan

GEOCHEMISTRY - 124 soil samples were collected from the area.

8) St.Mary's Falls area - 10 km E of Mount Morgan

GEOCHEMISTRY - Detailed stream sediment sampling was carried out in the area. 63 ridge and spur soil samples were collected from the area. 12 rock chip samples were also collected from the area.

9) Pearce's Prospect - 8 km E of Mt Morgan at the head of Station Creek.

GEOLOGY - The area can readily be divided into 4 geologically distinct, structurally separated zones. (a) Calcareous intermediate lithic tuffs - This sequence outcrops in the NE corner of the grid. It is part of the middle or early Upper Devonian sequence which stretches from the Dee River in the N to Friday Creek in the S. The contact between this sequence and the massive acid sequence to the SW is sharp and steep. (b) East of the Shear Zone - Massive Acid Sequence - This sequence consists of quartz- feldspar porphyry, feldspar porphyry, chert, and limestone. The cherts are poorly banded in part but usually massive white, grey, and green coloured. This sequence correlates with the Moongan Rhyolites, and is not identical to the Moongan Corridor which terminates at the Station Creek Fault. (c) West of the Shear Zone - Banded Sequence - This area consists of banded cherts, feldspar porphyry, acid lithic tuff, and minor quartz-feldspar porphyry, and appears to be correlatable with the area W of the Mt. Warner Shear Zone, and N of the Little Raspberry Linear. To the N the sequence is in faulted contact with quartz-feldspar porphyry, acid tuff and feldspar porphyry of the Moongan Corridor. There is considerable drag folding adjacent to the shear zone, and the movement sense is SW block downwards. (d) The Shear Zone - This zone of limestone, quartz-feldspar porphyry, fine acid volcanic, chert, and feldspar porphyry, is approximately 100 m wide. Outcrop and float are lacking, and the rock types are known from bedrock chips collected during the auger drilling.

GEOCHEMISTRY - Soil sampling was carried out over the area, returning 0 to 85 ppm Cu, and 0 to 190 ppm Zn. These are very low anomalies and the area is of little interest economically.

GEOPHYSICS - Trans-electromagnetics and self-potential surveys were carried out over the area.

10) Ajax Mine Prospect - 4 km SE of Mt Hopeful television tower.

GEOPHYSICS - Trans-electromagnetics and self-potential surveys were carried out over the area.

11) Fern Hills area - on the Dee Range, just W of "Fern Hills" homestead, S of Mt Hopeful television tower.

GEOLOGY - (The geology given here covers the Shadow and Penumbra areas, as well as the Fern Hills area). The rock sequence belongs to the Lower to Middle Devonian Capella Creek beds. It consists of massive acid lithic tuffs and fine acid volcanic rocks interbedded with fine grained intermediate volcanics and banded fine acid rocks. Lenses of recrystallised limestone 100 to 800 m long occur in the upper part of the sequence while major limestone beds can be traced on the E margin of the area. In the Fern Hills and Shadow area, these rocks are intruded by a quartz-feldspar porphyry unit and a massive, usually very coarse-grained hornblende andesite unit. The hornblende andesite encloses a very strongly sheared, sericitised and ferruginous siliceous rock, and to the E, is faulted against strongly sheared acid lithic tuff by the Fern Hills fault. Small and large andesite and feldspar porphyry dykes and less commonly microdiorite dykes are found throughout the area. The regional strike is approximately NW. The sequence has been folded into an assymetrical anticline (Penumbra Anticline) which can be traced from Fern Hills to Penumbra. The E limb of the anticline is terminated by the NW trending Fern Hills fault. This has produced a broad shear zone at least 1 km wide in the N. The contact between this zone and the Stockyard Creek Granodiorite is obscured by alluvium.

GEOCHEMISTRY - 15 stream sediment samples were collected. 153 ridge and spur soil samples were collected, returning 35 to 1160 ppm Zn, 20 to 350 ppm Cu, and 20 to 230 ppm Pb.

12) Penumbra area - Just W of the Fern Hills prospect, at the other side of the Dee Range.

GEOCHEMISTRY - 9 soil samples were collected. 31 soil samples were taken from the auger drilling. The majority of copper values are less then 200 ppm Cu, and Zn values less than 300 ppm. The analysis of the core from DDH48/1 returned values of less than 650 ppm Cu, and <130 ppm Zn. All assays for lead resulted in background values ranging between 14 and 50 ppm, and no gold was recorded.

GEOPHYSICS - Trans-electromagnetic and resistivity surveys were carried out over the area.

DRILLING - Diamond drill hole DDH48/1 was drilled to a depth of 101.58 m. This hole was drilled over the spot high of the best trans-EM anomaly. Subsequently three auger holes were drilled to depths of 20, 16, and 22 m on the second trans-EM anomaly.

13) Shadow area - 1.5 km S of the Penumbra prospect on the Dee Range.

GEOCHEMISTRY - Ridge and spur sampling was carried out, returning 5 to 300 ppm Cu, 15 to 80 ppm Pb, and 45 to 435 ppm Zn.

GEOPHYSICS - Reconnaissance trans-electromagnetic work was carried out.

14) Kangaroo Creek area - SW part of the Prior Park grazing farm.

GEOLOGY - The rocks in the grid occupy a N-S elongate embayment, open to the SW, within the Stockyard Creek Granodiorite. The rocks form part of a sequence of NW-SE striking limestones, acid lithic and feldspathic tuffs and acid feldspar porphyries of Mid-Devonian Capella Creek beds. To the E is a further, larger embayment within the Stockyard Creek Granodiorite, occupied by rocks of the same sequence; the Marble Mountain grid is located in this area. The rocks of the Kangaroo Creek Grid dip at approximately 45° to the NE and lie on the W limb of the Marble Mountain Syncline. The rocks in the area have been hornfelsed into crystalline limestone, garnetiferous limestone, garnet (-epidote) skarn, calc-silicate hornfels, and hornfelsed limey tuff. Acid feldspar porphyry forms a small outcrop in the W of the grid. The Stockyard Creek granodiorite forms the major part of the outcrop immediately W of the grid. To the NW is a prominent outcrop of finely banded acid aphanitic quartz porphyry and feldspar-quartz porphyry. It is most likely either a large xenolith of an intrusion. Extending S from the grid is a fairly continuous outcrop, principally of garnet skarn with lesser, sometimes weakly bedded, coarsely crystalline limestone and garnetiferous crystalline limestone. This is intruded to the W by a large acid feldspar porphyry dyke which trends approximately parallel to the strike of the limestones, but appears to dip to the SW.

GEOCHEMISTRY - Analysis of the soil samples from the auger drilling returned 12 to 170 ppm Cu, 40 to 190 ppm (mostly 70 to 90 ppm) Zn, 28 to 100 ppm Pb, and all values of Mo were below the limits of detection. 20 rock chip samples were also collected, returning 520 ppm to 0.09% Cu

GEOPHYSICS - Detailed trans-electromagnetic and self-potential surveys were carried out over the area.

DRILLING - 43 auger holes were drilled and samples were collected from the soil profile for geochemistry and bed-rock chip for subsurface geological interpretation.

15) Mount Bennett area - 10 km W of Mount Larcom township.

GEOPHYSICS - Detailed trans-electromagnetics was carried out over the area.

16) Riverhead area - Upper reaches of the Calliope River, W of Gladstone.

GEOLOGY - In the N part of the grid, the sequence dips to the S at 15-25°, over the E part of the grid a gentle swing in strike to NW-SE occurs and the dip steepens to 25-45°. The sequence consists of strongly outcropping acid volcanic rocks in the N of the grid area overlain by poorly outcropping sedimentary and pyroclastic rocks consisting largely of tuffaceous siltstone breccia-conglomerate, with horizons of acid lithic tuff, intermediate crystal lithic tuff and skarn. To the S of the grid, siltstone, fine sandstone, and greywacke comprise the greater part of the sequence. This largely sedimentary unit is intruded by three small biotite-quartz diorite stocks. No major faulting occurs in the grid area, except to the NW where a NE-SW trending fault brings in a sequence of acid feldspar porphyries with fragmental varieties, andesite, and minor greywacke and siltstone. A variety of dykes exist in the area, most are later in age than the stocks and are of little interest.

GEOCHEMISTRY - 585 soil samples were collected from the area. Over the W quartz-biotite diorite stock, copper values ranged up to 8500 ppm, with most values in the 1500 to 2000 ppm range. Values over the E stock are lower with most values in the 1000 to 1500 ppm range, with a high value of 5500 ppm. Copper values over the metasediments were 200 to 1000 ppm within 150 m of the stock and then decrease rapidly away to a local background of approximately 100 ppm. Copper values over the rhyolite and acid tuff in the N part of the grid are all less than 100 ppm. A granodiorite porphyry dyke to the N and NW of the W stock returned values of up to 7200 ppm Cu. Zinc values are generally less than 100 ppm over the stocks, as compared to 100 to 150 ppm over the sediments and pyroclastics. A rough correlation exists between anomalous zinc values of >200 ppm and outcrops of garnet-quartz- epidote skarn and epidote-quartz skarn. Only 5 anomalous values of Mo were recorded, with the highest values of 100 and 200 ppm Mo associated with the zone of high copper values over the W stock. All lead values lie in the range of 20 to 110 ppm, and none of these are considered anomalous. 9 rock chip samples were assayed

GEOPHYSICS - Ground magnetic and trans-electromagnetic surveys were conducted over the area.

DRILLING - A trial was made to drill through the alluvials with 4 auger holes drilled.

17) Upper Don area - at the head of the Don River.

GEOLOGY - The 1:250,000 geology map groups all the rocks in the area in the Middle Devonian Capella Creek beds. However, four distinct units were mapped in the area. They are as follows; (1) Dee Volcanics - This unit is presumed to be unconformable in the mapping area. Bedding in tuffaceous sandstones and conglomerates near the base of the unit gives a strike of 120-140° with dips of 15-30° to the SW. The oldest part of the sequence consists of poorly sorted, fine to medium grained, tuffaceous sandstones, intermediated feldspar crystal tuffs, chert, conglomerate, and acid lithic tuff. Overlying this is a unit composed largely of massive andesite with lesser intermediate tuff. Traces of malachite and sericite alteration are noted in these rocks in the SW of the area. The uppermost unit mapped of the Dee Volcanics comprises predominantly of lapilli tuff, and lesser bedded fine to medium sandstone. (2) Ulam beds - The rocks of this unit form the outcrop along the crest of the Calliope Range and form the major part of the outcrop in the streams draining down to the Don in the central part of the area. They are determined by a fault in the S bringing in rocks of the Riverhead Andesite. The sequence consists of acid to intermediate lithic tuffs, weakly banded pyrite-rich cherts, acid feldspar and quartz-feldspar porphyries, chert, conglomerate and breccia, greywacke, and siltstone. (3) Moongan Rhyolites - The relationship of these beds to the Ulam beds is uncertain as the contact is not visible and no structural information indicating the relationship can be obtained within the unit. In this area, the Moongan Rhyolite are a sequence of highly siliceous volcanic rocks, usually quartz and feldspar porphyritic, sometimes distinctly fragmental of containing a few percent of lithic fragments. In the S of the area, outcrops are largely of a quartz and quartz feldspar porphyry unit. Field evidence indicates this unit is flat lying and possibly intrusive. These outcrops contain more pyrite but less sphalerite than the Moongan Rhyolite rock further N. To the N, the above unit passes into crystal and lithic, fragmental acid rocks, almost all with the characteristic siliceous ovoids. (4) Riverhead Andesite - The 1:250,000 geology map shows these as Capella Creek beds, but Taube (1972) indicated a regional correlation with the Upper Devonian Dee Volcanics. These rocks were only mapped in the SE of the area, but are presumed to extend to the W to the Little Don fault. They consist of predominantly andesite, andesitic lithic crystal tuffs, conglomerate, sandstone, siltstone, greywacke, chlorite and hematitic intermediate lithic tuffs and minor fine acid rocks and chert.

GEOCHEMISTRY - 34 rock chip sample were collected.

18) Mannersley area - just SW of the Calliope River on the N edge of the Galloway Plains.

GEOCHEMISTRY - Soil samples were collected from over the whole grid by auger drilling. A total of 92 samples were collected. The highest copper value was 2120 ppm in the S of the grid, and molybdenum values ranged between detection limit to a peak of 32 ppm Mo.

DRILLING - Auger drilling was undertaken to obtain soil samples.

GEOCHEMISTRY - A total of 1186 core samples were collected and geochemically analysed. DDH 8- 73 returned trace to 2.55 gr/m tn Au, and trace to 0.88% Cu. DDH 7-39 returned trace to 5.85 gr/m tn Au, and trace to 3.3% Cu.

DRILLING - 5 diamond drill holes (DDH 5-28 WRO/2, DDH 7-39, DDH 7-42, DDH 8-73, DDH 3-35) were completed in the area. The holes were drilled to test different aspects of the geology and potentially associated mineralisation in the open cut area. DDH 7-39 was designed to test the quartz porphyry pipe under the Sugarloaf orebody. No ore grade mineralisation was encountered and the hole was abandoned at 409 m. DDH 7-42 was designed to test underneath the Slide Fault, N of the diorite porphyry dyke and S of the known mineralisation. The hole was terminated at 120 m, and no mineralisation was encountered. DDH 8-73 was designed to test the quartz porphyry pipe from a locality at the bottom of the pit. The hole reached 967.15 m, and indicated the presence of alteration at depth, but failed to indicate mineralisation of any significance. DDH 3-35 was drilled on the S edge of the opencut to test the S extension of the quartz porphyry pipe, and drilling is continuing.

2) Mine Anticline area - this area is in the Mt Morgan mine leases S of the opencut mine.

GEOCHEMISTRY - 79 core samples were assayed from DDH 38-12, returning trace to 0.30 gr/m tn Au of gold, and trace to 0.42% Cu.

DRILLING - 4 diamond drill holes (DDH 38-12, 38-13, 38-14, and 38-15) were completed in this area. DDH 38-12 was designed to follow-up massive sulphide mineralisation encountered in DDH5-20 towards the W. The hole reached a depth of 883.5 m and indicated the presence of weak mineralisation, but grades were too low to be of significance. DDH 38-13 was drilled in the S of the area, and was designed to test the "Lower Mine porphyries" for mineralisation at depth and to test the possible presence of a hydrothermal channel-way below the "magnetite blow" exposed at the other side of the Dee River. The hole was terminated at 520 m, and failed to indicate either a channel-way or mineralisation of any significance. DDH 38-14 was drilled to test for mineralisation in the "Lower Mine porphyries". The hole reached 514 m, but no mineralisation of significance were encountered. DDH 38-15 was designed to test the "Lower Mine porphyries" at depth for possible mineralisation. It failed to indicate mineralisation of significance and was terminated at 420 m.

3) Horse Creek area

GEOCHEMISTRY - Initially 56 rock chip samples were collected and indicated the presence of some highly anomalous Hg, and Se/Te values. Subsequently soil testing was carried out around three of the outcrops showing highest Hg values with 25 samples collected. This survey indicated that the anomalous rock values were reflected in the surrounding soils. After initial testing for Hg had proved successful, further rock-chip sampling was carried out over all outcrops in the area, with a total of 286 samples. The results will be available in next years report. Also three grids were surveyed over the three anomalous areas, and 663 soil samples were collected from the grids. Results from Grid A showed a pronounced anomaly in Hg, Te, Se, Zn, and Cu. The results from Grid B indicated the presence of a weak anomaly in Zn, Hg, and Cu over Au ironstone outcrop. Results from Grid C are not yet available. 97 core samples from DDH 31-1 were assayed, but the results are not yet available.

DRILLING - A short diamond drill hole (DDH 31-1) was drilled to test the anomaly in Grid A. The hole penetrated soil to a depth of 15 m, then entered quartz-feldspar porphyries and was terminated at a depth of 103.02 m in quartz diorite. No mineralisation of significance was encountered.

4) Mine Corridor South area

GEOCHEMISTRY - A total of 130 rock chip samples were collected over the area and assayed for Cu, Zn, Au, Hg, Se, and Te. The results show the presence of a few scattered, isolated anomalies.

GEOPHYSICS - A trial gravimetric survey was carried out but results are presently still under study.

5) Mount Battery area - located as a INPUT EM anomaly.

GEOCHEMISTRY - 44 soil samples were collected from the area and analysed for Cu, Pb, and Zn, but results failed to indicate anything of significance.

6) Bouldercombe area - A small part of the old Bouldercombe grid was re-established in order to follow- up a pronounced stream sediment anomaly.

GEOLOGY - The stream under investigation is apparently located at the contact between the Bouldercombe diorite and surrounding metamorphosed intermediate volcanic rocks.

GEOCHEMISTRY - 65 soil samples were collected from different levels in the auger holes and assayed, but no values of significance were encountered. The anomalous stream was re-sampled during different periods of the year, and the sampling extended to the area to the N across the highway. A total of 59 stream sediment samples were collected and assayed, as were 4 rock chip samples. Results positively indicated the presence of a strong zinc anomaly with, in certain areas, anomalous copper values. Follow-up work is being planned.

DRILLING - 14 Auger drills were completed in order to investigate subsurface geology. However, the presence of a thick fossil boulder bed prevented the successful completion of this program.

7) Struck Oil area

GEOLOGY - The sequence investigated this year consists of an andesite/andesitic tuff unit overlain by a tuffaceous sedimentary unit, folded into a syncline and anticline with fold axes striking N-S and passing to the E of the Struck Oil stock.

GEOCHEMISTRY - A short orientation biogeochemical (vegetation) survey was conducted over the known mineralisation to determine the suitability of this sample medium as a substitute for soil sampling. 363 samples were analysed for Cu and Mo. Results showed very poor reproducability and failed to show a significant anomaly contrasts. Another trial orientation survey was carried out by using the magnetic fraction of stream sediments and assayed. A total of 173 samples were collected, and in general, values from the magnetic fraction compared well with those from whole stream sediment samples. 30 rock chip samples were collected from gossans, skarns, dykes and alteration zones. The gossans and skarns returned anomalous Cu and W values, epidote alteration zones commonly were anomalous in Cu; while dykes failed to return any significant metal values. Hand augering soil sampling was conducted over skarn and alteration zones with a total of 43 samples collected. No samples returned significantly anomalous values. C-zone auger drill sampling was done on a systematic basis with 356 samples collected. Of the four gossan areas covered, only one returned significantly anomalous values and follow-up work is planned. 30 core samples form DDH's 2-13 and 2-14 were assayed. The assay results from DDH 2-13 indicate 30 m at 0.27% Cu, and 200 ppm Mo. The assay results from DDH 2-14 have not yet been received.

GEOPHYSICS - A ground magnetic and gravimetric survey were conducted over the area to test the area for possible buried stocks. The magnetics confirmed the presence of a low in the area, but appears to be too wide and shallow to be of interest from an exploration point of view. There has been problems with terrain corrections with the gravimetric survey. A short IP survey was done over the area indicated by the trans-EM survey, and the results confirmed the results of the trans-EM Survey.

DRILLING - Auger drilling was carried out over the grid to recover soil samples. Two more diamond drill holes (DDH 2-13 & 2-14) were completed in the area. DDH 2-13 & 2-14 were designed to test for near-surface economic mineralisation, and reached 44.53 m and 98.52 m respectively.

8) Mount Bennett area

GEOCHEMISTRY - 6 biogeochemical (vegetation) samples were collected to compare with grid soil values. 22 stream sediment samples were collected from the E part of the grid, but results were negative. Core samples from the drilling were analysed; DDH 14-1 returned 50 to 220 ppm Cu, 35 to 155 ppm Pb, 95 to 190 ppm Zn, 10 to 115 ppm Mo, <0.1 ppm Au, and <50 ppb Te; DDH 14-2 returned 5 to 60 ppm Cu, 10 to 20 ppm Pb, 35 to 65 ppm Zn, <2 to 2 ppm Mo, <0.1 to 0.2 ppm Au, and <50 to 1900 ppb Te; DDH 14-3 returned 50 to 210 ppm Cu, 10 to 20 ppm Pb, 40 to 80 ppm Zn, <2 to 30 ppm Mo, <0.1 ppm Au, and <50 ppb Te; DDH 14-4 returned 120 to 310 ppm Cu, 10 to 25 ppm Pb, 40 to 165 ppm Zn, <2 to 65 ppm Mo, <0.1 to 0.1 ppm Au, and 50 to 100 ppb Te; DDH 14-5 returned 50 to 150 ppm Cu, 10 to 100 ppm Pb, 35 to 105 ppm Zn, <2 to 50 ppm Mo, <0.1 ppm Au, and 16 to 750 ppb Te.

GEOPHYSICS - Part of the grid was covered by an IP survey, but results were not conclusive.

DRILLING - A total of 5 short diamond drill holes (DDH 14-1, 14-2, 14-3, 14-4, & 14-5) were drilled. DDH 14-1 & 14-4 (24.28 & 30.48 m respectively) were designed to test trans-EM anomaly peaks; DDH 14-2 (34.50 m) was designed to test a magnetic low; DDH 14-3 (17.78 m) was designed to test a magnetic high; and DDH 14-5 (33.17 m) was designed to try to determine the N extent of the granite encountered in DDH 14-2. DDH 14-3, 14-4, & 14-5 intersected fine-grained feldspar porphyry, and DDH 14-2 intersected granite. Minor pyrite was present in DDH 14-2 & 14-3.

9) Mannersley area

GEOLOGY - The prospect is underlain by a granodiorite porphyry stock which lies just to the N of the major Galloway Plains Tonalite. Mineralisation is mainly confined to a smaller biotite granodiorite stock within the granodiorite porphyry. The stock is bounded on the W by interbedded fine acid sediments, tuff, feldspar porphyry and andesite. The sedimentary/volcanic sequence has been assigned to the Lower Middle Devonian Mt Holly beds. Two narrow beds of magnetite have been located on the S position of the Mt Grim Ridge.

GEOCHEMISTRY - Initially ridge and spur soil sampling (79 samples) and detailed stream sediment sampling (162 samples) were used to indicate the extent of the Cu/Mo anomaly located in 1973. The grid was enlarged to cover this area. C-zone soil sampling was conducted over the grid with 724 samples collected. This sampling defined three anomalous areas of copper. The N Cu-anomaly covers a broad area trending approximately NE-SW. The central Cu-anomaly is the largest with peak values of 6800 ppm supported by several 1500 ppm Cu values. Both the N and central anomalies lie within the area of outcrop of the central biotite granodiorite stock. The S Cu-anomaly zone lies adjacent to, and trends roughly parallel to, the granodiorite - granodiorite porphyry contact. Molybdenum values define an area similar to that of the central Cu-anomaly, and has a peak value of 65 ppm Mo. Zn values define a number of slightly anomalous areas with a peak value of 760 ppm. No association appears to exist between soil geochemistry and rock types. Background values of lead were recorded over most of the grid. 500 core samples were assayed, but the results have not yet returned.

DRILLING - 3 diamond drill holes were completed over the area. DDH 43-1 was drilled to 201.40 m to test an IP anomaly. DDH 43-2 was drilled to 141.72 m to test the peak of the geochemical anomaly over the central part of the grid. DDH 43-3 was drilled to a depth of 149.33 m, and was drilled at the contact between the granodiorite porphyry and the biotite granodiorite.

10) Riverhead area

GEOLOGY - Mapping was carried out to the W of the Riverhead Grid where low order stream sediment values were recorded. An interbedded sequence of feldspar porphyry and siltstone, striking NW and dipping 20° to 30° to the SW, contains a number of narrow shears and breccias with associated quartz- epidote-chlorite alteration and minor pyrite. Granitic linear intrusions crop out in a number of places and carry pyrite but no copper mineralisation was observed.

GEOCHEMISTRY - 30 stream sediment samples and 8 rock chip samples were collected and analysed, confirming the presence of erratic, small Cu/Zn anomalies. 283 core samples were analysed. Assays from DDH 36-1 ranged from 330 to 1300 ppm Cu. DDH 36-2 returned 160 to 320 ppm Cu, 5 to 40 ppm Mo, and <0.1 ppm Au. Assays from DDH 36-3 ranged from 95 to 1500 ppm Cu. DDH 36-4 averaged 0.23% Cu. A 90 cm thick magnetite skarn intersected in DDH 36-5 returned 0.2% Cu.

DRILLING - Three short holes were drilled through the alluvial boulder beds W of the grid to test the country rock for possible underlying porphyry-copper style mineralisation. A combination of auger, hammer, and diamond drilling was used. DDH 36-1 was drilled to 24.02 m, and penetrated 10.37 m of boulder alluvial and then entered volcanic tuffs with quartz-pyrite veins. DDH 36-2 was positioned over a weak trans-EM anomaly and reached 21.59 m. The hole penetrated 16 m of boulder alluvium and then entered spotted and brecciated hornfels cut by narrow quartz/pyrite veins. DDH 36-3 was drilled to 19.95 m, and passed through fine-grained dacite and acid lithic tuff cut by numerous quartz/pyrite veins. Later in the year, two deep diamond drill holes were drilled in the N part of the grid. DDH 36-4 was drilled to 270.97 m and was positioned on top of a geochemical copper anomaly. Initially the hole penetrated intermediate volcanics and sediments but then entered the biotite granodiorite stock. Sulphides were distributed throughout the core. DDH 36-5 reached 106.98 m and was designed to test a sequence of volcanics and limey sediments for the presence of possible skarn occurrences. Mineralisation in this hole was less evident than in DDH 36-4.

11) Kangaroo Creek area - this area was a follow-up of an INPUT anomaly.

GEOCHEMISTRY - A total of 73 rock chip samples were collected from this area, including resampling of some areas that returned anomalous results previously. The anomalous values were not repeated and no further work is warranted in the area.

12) Fern Hills area

GEOCHEMISTRY - 85 soil samples were collected from the area. The results indicated the presence of a very small, but strong Zn anomaly.

13) Penumbra area

GEOCHEMISTRY - 67 soil sampling was collected from the hand augering, but no anomalous values of significance were returned. No further work is intended in this area.

DRILLING - Hand auger soil sampling was carried out over the trans-EM anomaly.

14) Ajax mine area

GEOLOGY - Rock types in the area are acid volcanics (aphanitic, porphyritic and fragmental varieties) of the Devonian Moongan Rhyolite sequence, mafic dykes, and a limited development of garnet- epidote skarns. The area lies near the junction of the Fern Hills Fault and an un-named linear lying to the W of it. Mineralisation is confined to a shear zone, coincident with an area of sericitic and siliceous alteration localised within a quartz-feldspar porphyry. Along strike to the NW the lode passes into unaltered, pyritic quartz-feldspar porphyry and to the S is covered by alluvium.

GEOCHEMISTRY - Two rock samples were taken from old workings and analysed.

GEOPHYSICS - One traverse of IP was carried out over the main peak of the trans-EM anomaly N of the old workings. No response of significance was recorded.

SUMMARY:

GEOLOGY -

REGIONAL - Northern Part of the ATP: The oldest rocks exposed in the N part of the ATP are the Middle Devonian Capella Creek beds. These comprise a lower intermediate sequence, a middle acid sequence, and an upper intermediate sequence. The Lower Capella Creek beds consist mainly of intermediate tuffs and calcareous tuffs with minor interbedded limestone, quartz-feldspar porphyry, feldspar porphyry, and acid lithic tuff. Most of the tuffs are well bedded. The middle acid sequence, the Moongan Rhyolite member, consists of mainly quartz-feldspar porphyry, feldspar porphyry, banded rhyolite and some acid tuff. The upper intermediate sequence, the Walmount beds, consists of intermediate tuffs and calcareous tuffs with some impure limestone. N of the Struck Oil Fault is a large mass of undifferentiated intermediate volcanic rocks (mainly intermediate to basic agglomerates and tuffs) whose stratigraphic position is uncertain; they were previously thought to resemble the Dee Volcanics in lithology, but are now considered part of the Lower Capella Creek beds. Further E is a sequence of similar rocks which appear conformable with the overlying Lower Carboniferous sequence and the underlying Moongan Rhyolites; these are thought to be the Upper Capella Creek beds (Walmount beds). Unconformably overlying these three rock units is a small residual of the Upper Devonian Dee Volcanics, which here consists of sandstone.

Central part of the ATP: There are large gaps in the mapping of this area, notably S of Mt Warner along the Ulam Range, and much of the regional geology remains interpretative. A generalised sequence is inferred from the compilation. The oldest rocks in this area are the Moongan Rhyolites (Quartz- feldspar porphyry (many of which are fragmental) with minor interbedded acid tuff, rhyolite, and fine acid rocks), which extend along the front of the range from Mt Warner almost to Fern Hills. Their broad area of exposure on the map is probably due to their occurrence in the nose of a broad anticline. Overlying the Moongan Rhyolite along the range from Mt Warner to Fern Hills is a predominantly acid fragmental sequence. The rocks here are inferred from mapping on the margins of the unmapped areas. The lithologies include, as far as is known, the Mt Warner sequence of chlorite clot fragmental rocks, acid and intermediate tuffs, quartz-feldspar porphyries, banded cherts, and limestone. Similar rocks, mainly acid fragmental rocks, occur along the range to the SE. These are here referred to as the Ulam beds. Overlying the Ulam beds is a broad synclinal area correlated with the Upper Capella Creek beds. These are predominantly intermediate tuffaceous rocks, with minor interbedded limestone, fine acid rock, acid tuff, feldspar porphyry, and sandstone; a central core in the syncline consists of quartz- feldspar porphyry and acid tuff. In the Emu Creek area the Capella Creek beds are unconformably overlain by the Dee Volcanics (abundant sandstone), as well as the more characteristic lithic tuff and andesite. A sequence of rocks (interbedded feldspar porphyry, fine acid rocks, and tuff) whose stratigraphic position is unknown occurs in the Upper Raspberry Creek area. These are here defined as the Upper Raspberry beds.

Southern part of the ATP: 1) Fern Hills to Mt Cedric Fault Zone - The oldest rocks in the S of the ATP are the Moongan Rhyolites, which crop out only in the Upper Don River area in what is thought to be the axial part of the major regional anticline. These are bounded on the W by a major fault, the Little Don Fault, which brings the Lower Carboniferous Pond Formation downwards into contact with these rocks. The Moongan Rhyolite is overlain by the Ulam beds (acid lithic and feldspathic tuff, chlorite clot fragmental rocks, and minor interbedded chert and rhyolite). Limestones occur here in the Ulam beds, and are abundant in the Mt Cedric-Stockyard Creek area. These have been referred to in a previous report as Mt Holly beds, but completion of regional mapping indicates that they belong to the Capella Creek beds. Overlying the Ulam beds is a sequence of rocks (mainly intermediate tuff with minor sandstone and limestone) referred to here as the Mt Cedric beds as they are best exposed on the N slopes of Mt Cedric. Overlying the Mt Cedric beds (possibly unconformably) is a sequence of interbedded intermediate tuff and argillite here defined as the Mt Alma Beds. The proportions of each rock type in the sequence vary. A predominantly argillaceous sequence occurs on the W slope of Mt Alma and has been traced S to Mannersley and N to Mt Bennett. Other predominantly argillaceous units occur, but the sequence as a whole is mainly intermediate tuff. This sequence continues eastward to the axis of the Almacoombe Syncline and is presumably repeated in descending order on the other side of the syncline. A massive andesitic to basic hornblende feldspar porphyry unit, the Ayrdrie Andesite, occurs within the Mt Alma beds and extends from Stockyard Creek to the Galloway Plains Tonalite. This unit is thought to be extrusive because of; (a) the presence of amygdules filled with calcite; (b) its interbedded nature with tuffs in its upper contact area SE of Mt Bennett; and (c) N of the Bullock Creek Fault an argillaceous member occurs within the unit. It is possible, however, that this unit is intrusive, as suggested by the position of similar rocks in other parts of the stratigraphy. Two residuals of an unconformable sequence occur on the W side of the Little Don Fault. The N one (SW of Kangaroo Creek) consists of 30 m of conglomerate overlain by an interbedded sequence of fine sandstone and quartz-lithic tuff. This could represent the basal member of the Dee Volcanics, but the presence of the relatively acid quartz-lithic tuff suggests a similarity to rocks of the Pond Formation on the other side of the Little Don Fault. For the present it is suggested to be part of the Dee Volcanics. The S residual occurs on the W side of the Upper Don area. It consists of sandstone, argillite and intermediate tuff, and it probably correlates with the N residual, although the lithologies are slightly different. About 2 km E of Mt Bennett, steeply-dipping tuffaceous and argillaceous units within the Mt Alma beds are overlain by a nearly flat lying conglomerate with granitic boulders and by more tuffaceous and argillaceous beds. Similar conglomerates occur on the S flank of Mt Alma and also along the range between Mt Alma and Mt Bennett. 2) South of Mt Cedric Fault Zone - The oldest rocks in the area are exposed in the core of the Ayrdrie Anticline along Alma Creek. They are thought to be equivalent to the Mt Cedric beds, and consist of intermediate tuffs with interbedded argillaceous sediments and limestone. They are overlain on the E flank of the anticline by the Ayrdrie Andesite and the Mt Alma beds, as discussed above. A major unconformity, possibly equating to that at the base of the Dee Volcanics, exists somewhere between this and the Ayrdrie Andesite to the E. On the W flank of the anticline there is further evidence for an unconformity. Along the W branch of Alma Creek the interbedded sediments and tuffs of the Mt Cedric beds show evidence of crumpling in the base of the creek; above these on the W side of the creek are nearly flat-lying fossiliferous sandstones. These sandstones are similar to the unconformable residue at the top of Mt Cedric and to others in the area. It is possible that they are all part of the basal member of the Dee Volcanics. Overlying the sandstone is the Riverhead Sequence, and is best defined in the Riverhead Area. It consists of a lower rhyolitic feldspar porphyry unit, a middle intermediate tuff unit, and an upper tuffaceous sandstone unit with a distinctive limestone horizon. The rhyolitic feldspar porphyry unit may be a local acid unit at the base of the more basic hornblende feldspar porphyry unit which occurs to the W. This unit appear to correlate with the Ayrdrie Andesite. The gross compositional change is difficult to explain, but the rocks are in fact spatially related and texturally similar in places. The Riverhead sequence is truncated stratigraphically above the tuff unit by the Galloway Plains Tonalite. 3) West of the Little Don Fault - Two unconformity surfaces have been demonstrated in this area. The rocks beneath these surfaces are undifferentiated but represent the oldest rocks in this part of the ATP. The northernmost unconformity surface, about 3 km E of the Pomegranate Granodiorite, is at the base of an interbedded sandstone-tuff unit considered to be part of the Dee Volcanics. Although faulting has complicated the picture in the area, the underlying rocks are andesitic and apparently belong to the Capella Creek beds. The southernmost unconformity surface appears to lie at the base of the Pond Formation. The Dee Volcanics appear to have thinned considerably or disappeared at this point. A small window of older rocks, possibly part of the Capella Creek beds, occurs adjacent to the S extremity of the Little Don Fault. The Pond Formation in this area consists of lithic tuff with characteristic coarse rounded boulders, quartz-lithic tuff (quartz-feldspar porphyry tuff), sandstone, and purple rhyolitic feldspar porphyry. The latter grades through fragmental and conglomeratic feldspar porphyry to purple lithic- crystal tuff. Disconformably overlying the Pond Formation at the S end of the ATP is the Youlambie Conglomerate. This comprises a lower sequence of mainly conglomerate and an upper sequence of mainly sandstone. It occurs as a basin-shaped unit on the S portion of the ATP and a residual adjacent to the Eulogie Gabbro.

Two major faulting directions are prominent in the ATP. A large amount of vertical block faulting occurs, and there are abundant minor faults of relatively small displacement. (1) East-Northeast. Faults belonging to this series tend to show considerable apparent horizontal displacement. In many cases such apparent displacement may be exaggerated due to relatively small vertical displacement of shallow-dipping beds, but in some cases, horizontal movement can be demonstrated by displacement of fold axes. Such displacement is demonstrable along the Struck Oil Fault, and the Mt Cedric Fault System. The Stony Creek, Mt Battery, and Centre Creek faults also belong to this system. (2) North- Northwest. Faults belonging to his series are often difficult to recognise because they are parallel to the regional strike of the rocks. One of the most important of these is the Mt Warner Shear. The Riverhead Fault appears to have a contradictory time relationship to that of the Mt Warner Shear Zone. This fault displaces the E-NE Mt Cedric Fault System, rather than being displaced by an E trending fault. Several faults appear to occur along major fold axes. The Ayrdrie Anticline is faulted along its axis, as indicated by the truncation of the limestone horizon in the Riverhead beds. The Fern Hill Fault is a major linear along which shallow-dipping beds W of the linear appear to be truncated and become steeply dipping E of the linear. The Almacoombe Syncline also appears to be faulted. Several traverses across this synclinal axis confirmed a major asymmetrical structure as depicted on the regional map but intermediate traverses showed only consistently flat-lying dips. This anomaly could be explained by invoking an unconformity at the conglomerate units in the Mt Alma beds, then invoking minor E-W vertical block-faulting to alternatively expose (horst) and cover (graben) the steeply-dipping beds on the other side of the syncline.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE - The areas relinquished include mainly granitic to gabbroic igneous rocks and moderately disturbed volcanic and sedimentary sequences, ranging in age from Lower Devonian to Tertiary. The area relinquished included the Poison Creek area, Youlambie area, Big Oaky grid, NE portion of the Eulogie Park Gabbro, Archer area, and Mount Bennett area.

SUMMARY:

REGIONAL EXPLORATION

GEOCHEMISTRY

- stream sediment sampling - The data from the regional stream sediment sampling program was compiled and compared to the geological plan. The copper plan shows the obvious area of smelter contamination SW of the Mt Morgan mine; the Bouldercombe contamination; the Dee Range anomalous zone comprising Moongan-Struck Oil-Mt Warner trend; the Fern Hills anomalous area; a broad zone of apparent high background in andesitic rocks of the Dee Volcanics and Pond Formation; the Riverhead- Divide anomalous area which is the most pronounced copper zone in the ATP; small anomalous zones associated with the contact zones in the Galloway Plains Tonalite; high back ground values in the Ayrdrie Andesite; and a discreet anomaly associated with the Mannersley Porphyry copper prospect. The zinc plan shows a similar area of smelter contamination to the copper plan; a trend of anomalous zinc roughly follows the Moongan Rhyolite, and is contiguous across the Station Creek Granodiorite with the Dee Range which is the largest zinc anomaly in the ATP, including the Mt Warner, Mt Alexander, and Fab areas; the Fern Hills anomalous zone occurring as a discrete area; a broad area of anomalous values on the W side of the Eulogie Gabbro, thought to represent high background in the Dee Volcanics; an anomaly in the Upper Don area thought to be associated with the Moongan Rhyolites; and a trend reflecting high background values in mainly sedimentary rocks overlying the Ayrdrie Andesite.

LOCALISED EXPLORATION/PROSPECTS

1) Mt Cedric area - 1 km N of Mt Cedric on the Alma Range, investigating a low-order geochemical anomaly with an associated magnetic high.

GEOLOGY - A small stock of biotite quartz diorite intrudes interbedded tuffs and sediments of the (?) Middle Devonian Capella Creek beds. The sediments dip to the E at 30 to 50° and are moderately faulted. GEOCHEMISTRY - Ridge and spur soil sampling was carried out over the area, but the results were generally low and the area is of no further interest.

GEOPHYSICS - Reconnaissance magnetic traversing was carried out, and the magnetic anomaly was shown to be due to magnetic material within the tuffaceous rock.

2) Divide area - investigating a low-order stream geochemical anomaly with an associated magnetic low anomaly near headwaters of the Calliope and Don Rivers.

GEOLOGY - The rocks consist of a sequence of andesite, andesitic tuff, and sediments of the (?) Upper Devonian - Lower Carboniferous Riverhead beds which are possibly equivalents of the Dee Volcanics - Pond Formation. The sequence dips SW at about 30° and is intruded by dioritic dykes and possibly a small stock.

GEOPHYSICS - Reconnaissance ground magnetics revealed a magnetic low in the S of the area. The profile suggests the presence of a granodiorite stock beneath the alluvium.

3) Gunpowder Creek area - near the headwaters of the Don River which returned weakly anomalous stream sediment values.

GEOLOGY - A small dioritic stock intrudes rocks of the Lower Carboniferous Pond Formation.

4) Lancefield area - on Manton Creek, approximately 2 km upstream from Lancefield Homestead.

GEOLOGY - A complex of quartz diorite, granodiorite, and gabbro intrudes tuffaceous sandstone and conglomerate of the Permian Youlambie Conglomerate.

GEOCHEMISTRY - Ridge and spur soil samples were collected, but the only values of any significance were the copper values in the gabbro which were of the order of 100 to 200 ppm Cu.

5) Upper Don area - headwaters of the Don River.

GEOLOGY - A window of possible Middle Devonian Rhyolites occur in this area beneath tuffs and sediments of the (?) Upper Devonian Dee Volcanics. The Moongan Rhyolite in this area consists of acid lithic tuff and quartz-feldspar porphyry. These rocks, and particularly a zone of ovoid silicification within them, contain high background values of zinc.

GEOCHEMISTRY - Ridge and spur soil samples were collected, and the results indicate a complex zone of anomalous values in the S part of the area.

GEOPHYSICS - A reconnaissance SP survey indicated a broad zone, low-order anomaly roughly coincident with the geochemistry.

6) Belgamba area - occurs in the ranges immediately S of Bouldercombe

GEOLOGY - Pyritic cherty horizons and jaspers occur within acid volcanics.

GEOCHEMISTRY - Chip samples of the pyritic cherts and jaspers did not return any anomalous base metal values.

7) Mount Morgan Mine

GEOCHEMISTRY - A geochemical orientation study has been carried out in the mine, with samples of unmineralised rocks of varying types, altered quartz-feldspar porphyries, quartz porphyry, quartz diorite, and associated alteration and various types of ore. It is hoped that these will yield data on primary dispersion haloes around the mine which may be useable in evaluating other prospects in the area. The details are being analysed. Core from the drilling program was assayed. The two bands of massive sulphides from DDH 3-37 were analysed and returned the following results; 252-254.4 m of 2.85 g/t Au and 11.16% Cu, and 272.4-279.6 m of 0.57 g/t and 2.18% Cu.

DRILLING - Deep exploration drilling continued. DDH 3-35 was designed to test whether massive sulphides at a depth of 600 to 750 m, intersected in DDH 5-28 and 8-73 were part of a continuous body. The hole reached 914 m, and only penetrated quartz porphyry with minor low grade disseminated pyrite, and a number of latite intrusions. DDH 6-55 & DDH 3-37 were designed to test the area beneath old mine workings in the Mt Morgan Extended area where high-grade copper had been recorded in 1923. DDH 3-37 intersected two narrow zones of massive sulphide mineralisation, and DDH 6-55 did not intersect any significant mineralisation.

8) Mine Corridor North - this large area also includes the smaller Linda Gully area, Arnold's Ridge area, Upper Mundic area and Baree Area. These small areas will be dealt with separately.

GEOCHEMISTRY - 177 rock chip samples were collected from outcrops, returning values of 5 ppm to 0.9% Cu, 5 to 780 ppm Zn, and 0 to 0.9 ppm Au. Most of the values are low-order, with only rare values showing anomalous character, defining four zones of anomalous values.

DRILLING - One of the four geochemical anomalous zones was diamond drilled.

9) Linda Gully area

GEOLOGY - This area contains a small magnetite skarn zone showing high Se, Te, Cu, and Zn.

GEOPHYSICS - The area was read with a magnetometer. The drill core was also examined with the magnetometer and the latite bodies were found responsible for the magnetic anomaly.

DRILLING - Diamond drill hole DDH 63/1 was put down to test the magnetic anomaly. The hole penetrated a sequence of quartz-feldspar porphyries which was cut by several latite intrusions.

10) Arnold's Ridge area

GEOLOGY - The area comprises Mine Corridor rocks with a zone of silicification and ferruginisation.

GEOCHEMISTRY - A low-order, broad zone of anomalous Se and Te has been shown by preliminary reconnaissance to be associated with the zone of silicification and ferruginisation.

11) Upper Mundic area

GEOLOGY - This area occurs north of a small embayment of the Mt Morgan Tonalite into the Mine Corridor. No alteration effects have been noted.

GEOCHEMISTRY - Low-order geochemical values have been returned from this area, but the significance has not yet been assessed.

12) Baree area

GEOCHEMISTRY - A discrete zone of copper-zinc anomalism was confirmed in this area; it had been previously reported by C.R.A. This area will be examined in detail in the coming year.

13) Mine Anticline area

GEOCHEMISTRY - 80 samples were collected of drill core from the "Upper Banded Mine Sequence" to determine whether the jaspers within the unit contain anomalous values of base metals. The results indicate anomalous base metals within the jaspers, with values increases with proximity to the Mt Morgan Mine. No further work is planned for this part of the Mine Corridor.

DRILLING - Diamond drill hole DDH 38/16 was drilled to 432.3 m, completing the drill-hole investigation of this area S of the Mt Morgan Mine. The hole penetrated the "Lower Banded Mine Sequence" to about 210 m, and the "Lower Mine Porphyries" from 210 m to its total depth of 432.3 m. Abundant intrusive latite was intersected in the drill hole. The hole generally confirmed the concept of a monoclinal fold plunging shallowly SE. No mineralisation of any significance was intersected.

14) Mine Corridor South area - the area extending from the section where the Dee River crosses the Mine Corridor to Horse Creek.

GEOLOGY - Detailed mapping was begun in the area using a grid and airphotos.

15) Horse Creek area

GEOCHEMISTRY - The geochemical results from DDH 31/1 (from within Grid A) were received with core from the weathered part of the core showing enrichment in Hg, Zn and Cu, while only low values were received from the fresh rock. This indicates possible remobilisation of values in the weathering profile from a source just uphill or adjacent to the peak of the surface anomaly. Grid A which covered the S end of the Horse creek alteration zone was extended to cover the whole zone and was soil sampled. Assay of the soil samples returned 10 to 250 ppm Pb, 10 to 370 ppm Cu, 25 to 2900 ppm Zn, <3 to 140 ppb Au, <50 to 350 ppb Hg, 150 to 1650 ppb Se, and <50 to 550 ppb Te. An anomaly in Cu, Zn, Te, and Se was revealed over the widest part of the alteration zone. Geochemical analysis of core samples from DDH 31/2 confirm the presence of the anomalous elements located in soil sampling, but values are generally somewhat lower.

DRILLING - Diamond drill hole DDH 31/2 was drilled in the soil anomaly identified in the extended Grid A. The alteration zone indicated on the surface was shown at depth to be similar to some parts of the alteration pipe in the Mt Morgan Mine, but is of lesser intensity, comprising mainly sericite alteration rather than the intense silica-sericite alteration in the Mine.

16) Horse Creek South area

GEOCHEMISTRY - Geochemical results show a low-order anomaly of Zn and Cu (10 to 480 ppm Zn & 2 to 270 ppm Cu), but their significance is no yet known.

17) Hamilton Creek area - this area was investigated to cover a large magnetic feature S of Horse Creek. This magnetic feature is suggested to have some similarities to the magnetic character of the Mt Morgan Mine.

GEOLOGY - Mapping of the area is presently being compiled.

GEOPHYSICS - A ground magnetic survey was begun but not completed.

18) Struck Oil area - This is one of the major porphyry-copper style occurrences in E Australia, but work was halted due to lack of encouraging results. A major compilation of all data is presently underway.

GEOLOGY - A major anticline and syncline pair occur just E of the Struck Oil Stock in Middle Devonian andesite and andesitic tuff. Several faults occur in the area, the two most important ones being the Mt Warner Shear trending NNW to the W of the stock, and the Struck Oil fault system. W of the Mt Warner Shear, the acid volcanics of the Moongan Corridor are abutted against this feature. North of the stock, the Struck Oil fault system separates a complex sequence of acid and intermediate volcanics.

GEOCHEMISTRY - The assays of core from DDH 2-14 were received and returned 80.7 m of andesitic feldspar porphyry averaging 0.11% Cu and 99 ppm Mo. Assays of core from DDH 2-15 averaged 0.16% Cu, and 180 ppm Mo over the length of the hole. DDH 2-16 averaged 0.15% Cu and 113.5 ppm Mo over a length of 134.1 m. Several relatively minor soil and rock chip surveys were carried out but plans for these have not yet been finalised.

DRILLING - 3 diamond drill holes were completed. DDH 2-15 reached 46.3 m and was designed to test for near-surface economic mineralisation. It followed a granodiorite porphyry dyke for its entire length and was abandoned for that reason. DDH 2-16 was drilled 15 m S of DDH 2-15 and was also designed to test for near-surface economic mineralisation. The hole reached 137.5 m, intersecting 118.4 m of tuff and tuffaceous sediments before bottoming in massive andesite. DDH 2-17 was designed to investigate a SP and magnetic anomaly. The hole reached 146.8 m without intersecting any ironstone, having passed through andesite for its total length. Magnetic material in the andesite accounted for the magnetic anomaly.

19) Mannersley area

GEOLOGY - A small complex stock has intruded a sequence of Carboniferous tuffaceous rocks, sandstone, limestone and siltstone about 1 km E of Mt Grim and N of the contact of the Permian Galloway Plains Tonalite. Copper is present as low-grade porphyry-style mineralisation in a late stage coarse grained quartz diorite intrusive within the complex intrusion.

GEOCHEMISTRY - The results from the core samples was received. For DDH 43/1, the average copper assay was 370 ppm Cu (highest value 0.2% Cu), and molybdenum ranged from 2 to 35 ppm Mo. For DDH 43/2, the average copper value was 0.12% Cu (peak value of 0.37% Cu), and molybdenum averaged 29 ppm Mo (peak of 520 ppm Mo). For DDH43/3, copper averaged 325 ppm Cu (peak of 0.28% Cu), and molybdenum averaged 19 ppm Mo (peak of 155 ppm Mo). In the light of these sub-economic results, no further work is planned.

20) Mt Grim area

GEOLOGY - A sequence of acid lithic tuffs with a fossiliferous limestone bed dips about 20° E and is intruded by the Mannersley Complex. The fossils have been identified as Lower Carboniferous. The area contains outcrops of magnetite-garnet-calcite skarn.

GEOCHEMISTRY - Ridge and spur soil sampling was carried out, but the only significant anomalous values received were in a zone within the main intrusive and a small zone on the margin. The low- order (10 to 270 ppm Pb, and 5 to 360 ppm Cu) and small size of these anomalies does not warrant further work.

GEOPHYSICS - Reconnaissance ground magnetics was carried out over the area, and the results indicate that there is no potential for significant tonnages of ore.

21) Ajax Mine area - the grid in this area was extended.

GEOLOGY - The mine occurs in a SW dipping sequence of rhyolite to dacitic rocks which are intensely altered in the mineralised area. Small pods of high-grade copper and zinc mineralisation occur in a concordant alteration zone up to 100 m thick.

GEOCHEMISTRY - Soil samples were collected from the auger drilling. The results are <2 to 880 ppm Cu, 5 to 1600 ppm Pb, and 15 to 8200 ppm Zn.

GEOPHYSICS - A ground radioactivity survey was conducted over the area, indicating a distinct potassic radiometric anomaly around the ore-bearing horizon, apparently reflecting sericitic alteration around this zone. A broad zone of anomalous potassic radiation also occurs in the SW part of the grid, also apparently reflecting sericitic alteration.

DRILLING - Auger drilling was conducted over the grid.

22) Fab area - occurs along strike from the Ajax Mine.

GEOCHEMISTRY - Soil sampling was carried out over the grid, returning 5 to 330 ppm Cu, 5 to 1400 ppm Pb, and 10 to 880 ppm Zn. Analysis of core returned a best intersection of 5 m averaging 2.05% Zn.

DRILLING - Auger drilling was carried out over the grid. One diamond drill hole was put down on an SP anomaly near the centre of the largest gossanous outcrop. The hole reached 165 m and intersected disseminated zinc-pyrite mineralisation in altered pyritic tuffaceous rocks. Pyrite occurred throughout the hole, varying from 5% to 25%. Hornfelsing in the form of biotite-cordierite was abundant throughout the hole.

23) Youlambie - this area is following up a INPUT - EM anomaly in the Youlambie Conglomerate.

GEOCHEMISTRY - Ridge and spur soil sampling was carried out over the area returning 5 to 170 ppm Cu, 15 to 125 ppm Zn, 10 to 30 ppm Pb, and 50 to 150 ppb Hg. These values are considered insignificant and no further work is warranted.

24) Moonmera - Lariat

GEOLOGY - A small breccia zone occurs on the approximate centre of a radial dyke swarm SE of the Moonmera porphyry copper prospect. It is probably part of the Moonmera mineralisation system.

SUMMARY:

LOCALISED EXPLORATION/PROSPECTS

1) Bull Creek area

GEOLOGY - Two quartz diorite batholiths occur in the area. The small one in the W referred to as the Bull Creek quartz diorite, while the one in the E, being an extension of the Mine and Town quartz diorite, is referred to as Town quartz diorite. In between these quartz diorite bodies volcanic rocks are found with general strike between 290° and 330°, and a general dip of 20° towards the S. Disseminated pyrite occurs mainly along the contact of the Town quartz diorite. The pyrite is present both in the quartz diorite and in the homogenous, fine grained andesite near the contact. It is considered to be a hydrothermal deposition related to a late stage of the quartz diorite intrusion. The copper mineralisation is also considered to have a hydrothermal epigenetic origin. Copper occurs as malachite and azurite in the cores of quartz diorite and feldspar andesite boulders. At places, pseudo-gossanous iron-stained rocks occur in outcrop.

GEOCHEMISTRY - Stream sediment sampling in the area returned 15 to 115 ppm Cu. 1375 soil samples were collected over the grid by hand augering. Copper content in soil was erratic in both range and distribution, and corresponded to the erratic distribution of the copper mineralised boulders noted in different exposures. Copper in soil ranged from 75 to 245 ppm Cu. Follow-up work was confined to 7 broad areas of anomalous copper content in soil. Three of the anomalous areas were over granodiorite, one near a basic dyke and the remainder associated with the mineralised conglomerate sequence. The anomalies were costeaned.

GEOPHYSICS - The ground magnetic and SP surveys did not return any results of interest. No further work was considered warranted.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE - The areas relinquished include mainly granitic to gabbroic igneous rocks and moderately disturbed volcanic and sedimentary sequences, ranging in age from Lower Devonian to Tertiary. The area relinquished included the Lancefield, Bull Creek, Archer, Mount Bennett, Stockyard Creek, Gunpowder Creek, Mannersley Porphyry Copper Prospect, and Craiglands area.

SUMMARY:

REGIONAL EXPLORATION

GEOLOGICAL MAPPING - Mine Corridor - The belt of siliceous rocks that host the Mount Morgan Mine and other prospects that have been investigated in the past. A major program of semi-regional work was done on this area during the year. The stratigraphic sequence in the Mine Corridor is known from geological mapping and diamond drilling, mainly in the area of the Mine. Its top and bottom has not been defined, but the sequence as a whole is correlated with the Moongan Rhyolite sequence. The known sequence in the Mine Corridor is defined as follows, in order of decreasing age; (A) Lower Mine Porphyry (LMP) - The LMP together with the Banded Mine Sequence are the host rocks for the Mt Morgan orebody. The LMP are known only from exposures within the Mt Morgan open cut and from diamond drill holes within and around the pit. The total known thickness is about 850 m. Away from the mine, the LMP consists predominantly of massive quartz-feldspar porphyry with rare fragments and relatively sparse phenocrysts. The sequence also includes highly fragmental varieties with quartz-feldspar porphyry matrix. The fragmental types show a wide variety of fragmentals including dark chloritic rocks, porphyritic rocks, light-coloured cherty rocks, limestones, and rare to occasional sulphide fragments. (B) Banded Mine Sequence (BMS) - The BMS is considered to represent the approximate time equivalent sequence to the Mt Morgan orebody (i.e. probably deposited on the sea floor at or just before the time the orebody was formed sub-surface). It is best defined in and around the open cut and in diamond drill cores in the Mine Anticline area. The characteristic feature of this sequence is the presence of thin (2-10 cm) jasper beds in the upper part of the unit. These are interbedded with acid to intermediate crystal tuffs (averaging 10-20 cm thick), some larger massive chert beds, and massive and fragmental quartz-feldspar porphyry as in the LMP. Pyritic beds within the sequence carry anomalous amounts of iron, manganese and zinc which increases in value with proximity to the mine. The base of the sequence is defined as the limestone layer which is exposed on the N side of the open cut. Where this limestone is not present, the definition of the boundary of the BMS becomes more difficult to determine, and is suggested as the change from banded rocks to homogeneous quartz-feldspar porphyry. The total thickness of the unit is about 200 m in the mine area, but is greater in some area. (C) Upper Mine Porphyries (UMP) - The UMP are exposed E of the open cut, in the North and South Corridors, and are known from diamond drill holes E of the open cut. They consist of massive fragmental quartz-feldspar porphyry, with rare minor cherty and limestone interbeds. Coarse quartz phenocrysts (5 mm) are characteristic of the unit. The fragments consist mainly of chert, jasper, quartz-feldspar porphyry, and relatively minor limestone fragments. Rare pyrite and magnetite fragments have been observed, mainly in core from diamond drill holes S and E of the open cut. The UMP is relatively homogenous for most of its thickness of 850 m. (D) Arnold's Ridge Felsite - This is a massive fine acid unit with minor fine quartz and feldspar phenocrysts. It overlies the Upper Mine Porphyries in the Arnold's Ridge area. The lower contact is interbedded with coarse quartz-feldspar porphyry of the UMP. The upper contact grades into coarse quartz-feldspar porphyry similar to the UMP but with fewer phenocrysts. (E) Baree Felsite - Most of the N lobe of corridor rocks consists of light-coloured fine grained to aphanitic siliceous rocks, with minor areas of quartz porphyry, quartz- feldspar porphyry, and lithic tuff. These areas are probably the highest part of the stratigraphic sequence in the mine corridor, but their stratigraphic position is uncertain because of a major intrusion of granodiorite between these and the Arnold's Ridge Felsite. (F) Undifferentiated - A sequence of fine-grained quartz-feldspar porphyry occurs in the Upper Mundic area but its stratigraphic position is uncertain. Its contact with the UMP is thought to be faulted. Similar fine-grained acid rocks occur in the Horse Creek and Hamilton Creek areas. (G) Intrusive Rocks - Quartz latite, previously referred to as "Old basics" or "Andesites" occurs abundantly as irregular dyke and stock-like bodies within, and especially in an annular zone around, the mine. They post-date the mineralisation, but in places are themselves mineralised, sometimes reaching economic grades. The Mount Morgan Tonalite intrudes the Mine Corridor sequence and the quartz latites. Late dilation dykes of Permian age occur in anomalous abundance in the mine area. They show a wide variety of textures but are mainly andesitic in composition. The main trends of these dykes are NW and NE.The boot-shaped Mount Morgan orebody occurs within the Lower Mine Porphyries in the central part of the domal structure define by the BMS. The heel part of the boot, known as the Main Ore Pipe, consists of massive sulphide mineralisation with greater than 50% sulphides. The toe part of the boot, known as the Sugarloaf orebody, consists of disseminated and stockwork mineralisation with less the 20% sulphides. Mineralisation in the orebody consists mainly of pyrite with lesser chalcopyrite, pyrrhotite, magnetite, and sphalerite. Economic amounts of gold and gold telluride are also present. Alteration, consisting mainly of silicification and pyritisation of the host rocks, occurs in an envelope around the orebody.

LOCALISED EXPLORATION/PROSPECTS

1) Mount Morgan Mine

GEOLOGY - The Mount Morgan open-cut mine was re-mapped in preparation for the visit of the International Geological Congress. The mapping generally confirmed the classification of the Mt Morgan orebody as a "volcanogenic massive sulphide" deposit. The mine consists of a pipe-like massive pyritic copper-gold deposit underlain by a disseminated "stringer zone" of siliceous ore. The orebody occurs within a large siliceous alteration pipe which transgresses the acid volcanic rocks of the Middle Devonian (?) Capella Creek beds. Owing to faulting and tilting of the stratigraphic sequence, the lower "stringer zone" is now at the same level as the upper "massive zone". Relocation of the Slide Fault and tilting of the sequence from a NE dip to near horizontal returns the mine to its original position.

GEOCHEMISTRY - Values from the core of DDH 3-38 were very low, reaching maximum values of 1.5 g/t Au, and 0.35% Cu.

DRILLING - One diamond drill hole, DDH 3-38, was put down in the Sugarloaf area to test for mineralisation beneath the "false gossan" under the Mundic Creek tailings dam. The drill hole reached 245.55 m, intersecting gossanous and highly pyritic quartz porphyry for most of its length.

2) Peacock Shaft area - High-grade mineralisation was reported from the old Peacock Shaft put down in about 1900. The shaft is presently covered by the Horse Paddock dump.

DRILLING - A diamond drill hole was put down to intersect the mineralisation recorded in the old shaft. The hole reached 110.36 m and intersected mainly quartz-feldspar porphyry with some latite to a depth of 85.46 m, after which it passed into massive latite. No significant mineralisation was intersected. The reported ore may still be present, but is probably on either side of the latite intrusion.

3) Mine Corridor South area

GEOCHEMISTRY - Rock chip samples were taken from the area, returning 140 to 195 ppm Cu and 150 to 490 ppm Zn.

4) Talban Hill Breccia Pipe - This area is 1.5 km S-SE of the Mt Morgan Mine, and is also known as the Light of Day Mine.

GEOLOGY - The Talban Hill Breccia Pipe is an intensely altered breccia zone occurring on the contact of the Mine Corridor rocks with the Mount Morgan Tonalite at the N end of the Mine Corridor South. The pipe is boomerang-shaped on the surface and appears to extend conically outwards at depth. Breccia fragments within the pipe consist of fine siliceous Mine Corridor rocks and tonalite, all of which are set in a fine altered matrix which is often highly pyritic. Some of the breccia fragments of rhyolitic rock are also pyritic.

GEOCHEMISTRY - Analysis of material from the drilling yielded 0 to 0.15 g/t Au, 24 to 184 ppm Cu, 24 to 66 ppm Pb, 18 to 132 ppm Zn, and 0 to 5 ppm Mo. These values are not significant suggesting that the earlier sampling of underground workings may have been false. On the other hand, the percussion holes were not very deep and most of the recorded values from the old workings were from lower down. The drilling material did return highly anomalous values for selenium and tellurium (3500 ppb and 1250 ppb respectively). Material from a diamond drill hole (DDH MC1) put down by North Broken Hill in 1969 was split and assayed. It returned no gold values of significance over the whole of the intersection.

DRILLING - 3 percussion holes were drilled.

5) Baree area - 1 to 2 km N and E of the Mt Morgan Mine, in the NW part of the Mine Corridor.

GEOLOGY - The area is underlain by coarse quartz-feldspar porphyry of the UMP, the Arnold's Ridge Felsite, and the Baree Felsite. Aplite granite bounds the acid volcanics of the Corridor Rocks on the NE. The Corridor rocks are apparently dipping to the NE but their attitude in unknown. They are intruded by (early) latites and (late) Permian dykes of andesitic composition.

GEOCHEMISTRY - Soil sampling was carried out over the area. Copper and zinc values show broad, nearly coincident anomalies which tend to be associated with latite intrusions and also occur within the granite. Copper reaches a peak of 1000 ppm Cu, and zinc reaches 1250 ppm Zn. Se and Te were only sampled in the lower part of the grid. Peak values of 1300 and 150 ppb, respectively, were reproduced over an area of alteration (silicification and ferruginisation) in the Arnold's Ridge Felsite. These results were disappointingly low compared to the rock chip values in the area, which reached peaks of 7000 and 1250 ppb, respectively, in previous years.

6) Morganite and Great North Lode areas - 2.5 and 3 km N of Mt Morgan mine respectively.

GEOCHEMISTRY - Rock chip samples were collected from the area returning 10 to 290 ppm Cu, <5 to 15 ppm Pb, 5 to 230 ppm Zn, and <3 to 15 ppb Au. The copper values show discrete anomalous zones in both areas. The values for zinc, lead, and gold were only back ground values. Soil sampling was also carried out, returning 5 to 470 ppm Cu, 10 to 30 ppm Pb, 2 to 160 ppm Zn, and 9 to 90 ppb Au. The adit in the Great North Lode was chip-sampled along its length and analysed, returning 45 to 860 ppm Cu, 10 to 30 ppm Pb, 10 to 460 ppm Zn, and <0.1 ppm Au.

7) Fab area

GEOCHEMISTRY - A soil survey was carried out, returning 5 to 420 ppm Cu, 10 to 4000 ppm Pb, 20 to 3400 ppm Zn, <1 to 7 ppm Ag, and 10 to 8400 ppm Mn. Mineralisation in the core from DDH 69/2 is weak, with maximum values of 0.52% Zn, and 0.13% Cu.

DRILLING - Detailed hand auger sampling was carried out over the area. Two diamond drill holes were put down. DDH 69/2 was put down to test an SP anomaly, reaching 126.6 m and intersected semi- massive pyrite (20 to 50% pyrite) zone within acid volcanics from 98.7 to 109.8 m. The rocks are strongly foliated throughout the length of the hole. DDH 69/3 was designed to show the stratigraphic sequence through the mineralised zone and the iron-manganese cherts. Two major pyritic zones within a sequence of silicic cherts, tuffs and fragmentals were intersected. The lower zone contains weak and sporadic disseminated sphalerite.

8) Ajax-Omo area - the Ajax grid was extended to cover the Omo alteration zone. A tribute arrangement was made with a local miner to work the Ajax Mine. The small shaft was deepened from 12 m to 20.5 m and encountered a small rich pod of massive chalcocite associated with a banded pyritic zinc lode. Production from the mine for the period 1.7.75 to 30.6.76 was 17.8 g Au, 2661.6 g Ag, and 3.82 t Cu from 49.8 t of ore.

GEOLOGY - A zone of surface mineralisation and alteration was defined in a gentle anticlinal structure parallel to, and in the same horizon as, the Ajax structure. Re-mapping of the area, with information from the drilling, seems to indicate that the mine is a stratiform massive sulphide emplaced in a (?) sheared anticlinal fold nose, associated with jaspers and manganiferous sediments.

GEOCHEMISTRY - Soil sampling was carried out over the area, returning 2 to 800 ppm Cu, 0 to 1600 ppm Pb, 15 to 8200 ppm Zn, 15 ppm to 0.14% Mn. The core from the drilling was assayed, and the results from DDH 47/3 returned maximum values of 0.6% Cu, 360 g/t Ag, 10% Zn, 1.1% Pb, and 6.0 g/t Au, but the values were too patchy to be considered as ore. DDH 47/4 returned 0.96 to 10.8% Zn, 6 to 800 ppm Ag, and 0.2 to 4.1 g/t Au (one value of 19.2 g/t Au). All the mineralisation occurs within strongly altered and pyritic lithic tuffs with patchy and disseminated sphalerite. DDH 47/5 intersected a zone of strong biotite-chlorite-dolomite alteration, between 92.5 and 102.7 m, but contained no significant values. The material from the percussion drilling was assayed and returned 5 to 1760 ppm Cu, <5 to 1900 ppm Pb, and 45 to 11000 ppm Zn.

GEOPHYSICS - The area was covered by ground radioactivity

DRILLING - Three more diamond drill holes (DDH 47/3, 4, and 5) were put down in the Ajax area. DDH 47/3 was put down to test for further shallow secondary Cu mineralisation in the area. DDH 47/4 was drilled to test the extension of the Ajax mineralisation zone to the SE beneath the eastern river gravels. DDH 47/5 was drilled to test a coincident geochemical and trans-EM anomaly. The hole passed through a sequence of grey siliceous fine acid rocks cut by numerous andesitic dykes. A program of percussion drilling was carried out in the alluvial areas S of the mine to test whether the geochemical anomaly extended beneath the alluvium.

9) Drive area

GEOCHEMISTRY - Soil sampling showed low-order Zn values associated with the gossanous zones, reaching a maximum value of 1000 ppm Zn. Copper, lead, silver and manganese returned only background values.

10) Grillo Hill area

GEOLOGY - A pyrite rich horizon from 50 to 100 m thick occurs in a sequence of andesitic to rhyolite tuffs and siltstones in a major anticlinorium along the front of the Dee Range. Two weakly gossanous altered zones occur within the horizon.

GEOCHEMISTRY - Soil sampling was carried out, returning 10 to 660 ppm Cu, 10 to 1200 ppm Zn, and 75 to 14500 ppm Mn.

11) Upper Don area

GEOLOGY - Geological mapping outlined a (pyritic) mineralised zone approximately 800 m in strike length and 25-125 m wide.

GEOCHEMISTRY - The grid was soil sampled by a hand auger. Copper shows a broad zone of high background values on the S end of the grid which apparently reflects high background geochemistry in the basic to andesitic suite of volcanics. N of the fault, the acid volcanics have only low background copper values, and several discrete anomalous zones occur associated with the gossanous zones. The maximum copper value is 740 ppm. Lead generally shows very low background values. A broad zone of low-order anomaly occurs approximately coincident with the copper zone in the central part of the grid, but does not occur over the E copper zone. This anomaly is open to the N. Zinc shows a major broad anomaly associated with copper. The maximum value reached was 0.23% Zn, and the anomaly is open to the N.

GEOPHYSICS - A ground radiation survey was carried out over part of the grid. This showed a broad weak potassic radiometric anomaly stratigraphically above the gossanous zones. The uranium channel showed an unusual linear anomaly for which no explanation has been found. A SP survey was also carried out over part of the grid, and showed a broad low associated with the topographic high and also with the gossanous areas.

DRILLING - Hand augering was carried out to obtain soil samples.

12) Quarry Creek area

GEOLOGY - A large part of the area is covered by a usually massive, intermediate to basic rock, tuffaceous and fine banded varieties do occur. This unit appears to be flat lying or gently folded. Three other units also occur in the area; a foliated aphanitic andesite unit; a feldspar porphyry lithic tuff; and an intermediate lithic tuff/tuffaceous shale unit which constitutes the bulk of the sequence in the W part of the grid. Basic and acid dykes also occur in the area.

GEOCHEMISTRY - A soil survey was carried out, returning 15 to 175 ppm Zn, 5 to 35 ppm Pb, and up to 350 ppm Cu. None of these values are anomalous, and no further exploration is warranted in the area.

13) Moonmera Porphyry Copper Prospect - Two areas were looked at in detail, these are the Moonmera Triangle area and the Moonmera Quarry Breccia zone.

(A) Moonmera Triangle area (central part of the prospect) -

GEOCHEMISTRY - Soil sampling was carried out, returning 180 to 5000 ppm Cu, and 2 to 112 ppm Mo. The values are anomalous over the alteration zone in the No.3 shaft area, and a weaker zone above the DDH MM 13, put down by North Broken Hill. Core from DDH 61/1 (between 9 and 17 m) was assayed, returning an average of 1.14% Cu with negligible Mo. Core from the hole in the No. 3 shaft area yielded an average of 1.05% Cu between 11.0 and 18.0 m.

DRILLING - Two short diamond drill holes were put down in the alteration zone around DDH MM 13, to test the possibility of a small tonnage ore zone. DDH 61/1 reached 30.5 m, drilling through a shallow-dipping quartz monzonite porphyry dyke into intensely altered (?) granodiorite with coarse breccia-style mineralisation. The second drill hole was 30 m to the W of DDH 61/1. It intersected altered (?) brecciated granodiorite for the entire length, except for a 10.5 m thick dyke. The alteration zone was unfortunately only very weakly mineralised. A third diamond drill hole was put down on the geochemical anomaly of the No. 3 shaft alteration zone. The hole intersected weakly mineralised altered rock to a depth of 28.97 m.

(B) Moonmera Quarry Breccia Zone

DRILLING - 6 short diamond drill holes (DDH 61/4 to 61/9) were completed in the area.

SUMMARY:

LOCALISED EXPLORATION/PROSPECTS

1) Mount Morgan Mine

GEOCHEMISTRY - Material from the drilling was assayed. Several of the drill holes, notably PDH. No.1 (3 bench) and No.C. (4a bench) yielded 3 m lengths assaying 8000 ppm Zn. One intersection (No.1-4a bench) yielded 1.58% Cu and 1.2 g/t Au in one 3 m intersection.

DRILLING - A program of percussion drilling was carried out to test a small stratiform zone of Cu-Zn mineralisation in the NE corner of the open cut. Diamond drill hole DDH 3-39 was put down to follow- up, at depth, the anomalous values recorded in percussion hole No.1-4a bench. Logging of the core showed that the Banded Mine Sequence of interbedded jaspers, cherts, and tuffaceous quartz-feldspar porphyries contained the values. The holes demonstrated that the stratiform Cu-Zn mineralisation occurs within the top part of the BMS. One other percussion drill hole was put down further N to test the top of the BMS. No significant values were intersected.

2) Mine Corridor North

GEOPHYSICS - A major Gradient Array IP survey was carried out over most of the grid area. The only feature of any significance was a very large anomaly extending N of the Horse Paddock Dump in a SE direction to the Walterhall area. The anomaly is broad in the NW but sharp in the SE. The peak of the anomaly is within the Mount Morgan Tonalite. A bulldozer uncovered an old water pipe which appeared to be the source of the sharp peak of the IP anomaly.

DRILLING - Percussion drilling was carried out to investigate the IP anomaly. The drilling, together with the bulldozing which uncovered the water pipe, showed conclusively that the peak of the IP anomaly was caused by the water pipe but the broad zone extending to the NW was caused by anomalous amounts of fine pyrite within the alteration zone. A diamond drill hole (DDH 63/3) was put down adjacent to Bond's Shaft (about 0.7 km N of Mt Morgan mine). The hole intersected banded mine sequence from 164 m to 360.5 m, with pyritic skarn zone from 357 to 360.5 m. The skarn contained low values of chalcopyrite and sphalerite.

3) Arnold's Ridge area

DRILLING - A diamond drill hole was put down on the Arnold's Ridge alteration zone to test the IP anomaly and the alteration zone. Geochemical basemetal background values, amount of pyrite, and intensity of alteration showed an increase with depth to 96 m, then decreased from 96 to 293.2 m.

4) Linda Gully area - 1 km N of Mount Morgan Mine. Several shafts and adits had been put down in the area in about 1900.

GEOCHEMISTRY - Samples of the skarn returned values of 1.5% Cu and 2.0 g/t Au. Results of assays from core have not been received yet.

DRILLING - Two diamond drill holes were put down to test the stratigraphy beneath the limestone- magnetite skarn. DDH 63/5 intersected a major porphyritic diorite dyke at 100 m, and was abandoned. DDH 63/6 was moved 50 m back from DDH 63/5. It collared within the porphyritic diorite dyke and drilled out of it into UMP at 90.6 m. The hole was drilled to 980.0 m and penetrated the BMS at 640 m.

5) Thomases Gossan area - 7 km N of the Mount Morgan Mine. Limited tonnages of high-grade ore were extracted from small workings in the area.

GEOLOGY - The area consists of Mine Corridor-type rocks, but occurring within the Moongan Corridor, which is similar in composition but is separated from it by a granodiorite body and may not be correlateable. The old workings occur mainly in fine acid and andesitic volcanic rocks in a greater sequence of acid volcanic rocks. Quartz-feldspar porphyry occurs in the E part of the grid. These rocks are unconformably overlain by the Jurassic Razorback beds. The high-grade lode which was mined was obviously secondarily enriched beneath the Razorback beds. The lode may have been a small vein associated with the Moonmera porphyry copper system 1 km NE, or could possibly be a stratiform bed within the Moongan Rhyolite.

GEOCHEMISTRY - Assays of soil sampling showed a zone of contamination below the old workings and an apparent zone of dispersion up into the Razorback beds. A slightly anomalous zone of copper (to 260 ppm) appears to follow the unconformity. A spot high of 320 ppm Cu in the Razorback beds may represent contamination. Lead values range from 5 to 30 ppm and are not considered anomalous. Zinc values show a concentration along the base of the Razorback beds similar to that shown for copper. A low-order anomaly (150 ppm Zn) occurs higher in the Razorback beds, also corresponding with a copper anomaly. Its cause is unknown.

DRILLING - Hand augering to collect soil samples was carried out. 14 percussion drill holes were put down to see whether any small pods of high-grade ore could be recovered with no success.

6) Moonmera Porphyry Copper Prospect - The No.2 and No.3 shaft areas were investigated during this year.

(A) No.2 Shaft area

GEOCHEMISTRY - Material from the percussion drilling was assayed. The best intersections were from PDH 43 with 8.1 m averaged at 1.59% Cu; PHD44 with 18 m averaged at 0.62% Cu; and PDH45 with 21 m averaged at 0.73% Cu. The diamond drill hole returned no mineralisation of significance.

DRILLING - The zone was tested with fifteen shallow percussion drill holes, one of the holes was continued by diamond drilling.

(B) No.3 Shaft area

GEOLOGY - The shaft in this area was sunk on an intensely altered malachite-stained knob of quartz- sericite porphyry about 50 x 50 m. Geopeko in 1976 put down a short diamond drill hole (30 m deep) adjacent to the shaft, returning 7 m of 1.05% Cu, and negligible Mo.

GEOCHEMISTRY - Geochemical values from the percussion drilling material did not reproduce the values intersected in diamond drill hole. Most copper values were less than 0.1% Cu. The highest value intersected was 2.95% Cu in one unsupported 3 m sample. The zone is considered to be of no further interest.

DRILLING - 6 percussion drill holes were put down to follow up Geopeko's diamond drill hole.

7) Ajax Mine area

GEOCHEMISTRY - The best values from the percussion drilling in the N zinc anomaly were 2.25% Zn and 349 ppm Cu over 4 m in PD 21. The best intersection from the drilling in the E geochemical anomaly was 0.17% Pb, 12.6 g/t Ag and 0.25 g/t Au over 6 m. The significant results from DDH 47/7 were 97 to 103 m returning 0.19% Cu, 0.1 g/t Au, 0.1 g/t Ag, and 2.5% Zn; 103 to 109 m returning 0.71% Cu, 0.1 g/t Au, 5.8 g/t Ag, and 4.84% Zn; and 109 to 114 m returning 0.13% Cu, 0.4 g/t Au, 10.95 g/t Ag, and 2.18% Zn.

DRILLING - A program of percussion drilling was carried out for shallow testing beneath alluvial flats for geochemical purposes, and deeper testing beneath previously defined geochemical anomalies. 23 holes were drilled for a total of 547 m. Holes drilled on the N zinc anomaly intersected weakly mineralised and altered tuffs interbedded with cherts and jaspers. Holes in the E geochemical anomaly intersected only weakly mineralised tuffs which suggests that this zone has little ore potential. One hole drilled on the trans-EM anomaly intersected a body of magnetic dolerite with no mineralisation. A diamond drill hole was designed to test the strike extension of the mineralised zone which was worked underground. The hole reached 118.6 m when it was realised that it was drilling over the plunge of the anticline to the E, and would not intersect the favourable horizon, and was so stopped. A second hole, DDH 47/7 was designed to drill down the fold axis. Patchy copper and zinc mineralisation was intersected between 97 and 125 m depth.

8) Fab Prospect

DRILLING - 4 percussion drill holes were drill on various SP, geochemical and trans-EM anomalies. Holes 1 and 2 intersected pyritic zones in fresh rock, but no base metal sulphides are visible. Hole 3 passed into gneissic rock close to the granodiorite contact and was terminated short of target. Hole 4 intersected an andesite dyke with no pyrite.

9) Omo Prospect

GEOLOGY - This prospect consists of a very small gossanous zone within a large intense alteration zone W of and contiguous with the Ajax alteration zone

GEOCHEMISTRY - The core from DDH 70/1 was analysed, and the significant values are 147 to 155 m at 0.187% Zn; 150 to 151 m at 0.15% Cu, and 188 to 192 m at 0.44% Zn.

DRILLING - A diamond drill hole (DDH 70/1) was put down underneath the gossanous zone to test whether the zone had any depth extent. The hole reached 269.5 m and intersected two zones of minor pyrite-sphalerite-chalcopyrite mineralisation, between 147-156 m and 165-187 m.

SUMMARY:

LOCALISED EXPLORATION/PROSPECTS

1) Linda Gully area

GEOCHEMISTRY - Analysis of core from DDH 63/6 returned 5 to 660 ppm Cu, <5 to 430 ppm Pb, and 65 to 270 ppm Zn. None of these results area considered anomalous.

2) Upper Mundic area

GEOCHEMISTRY - Analysis of cuttings from PDH 7 and core from DDH 63/7 returned 10 to 780 ppm Cu, 5 to 60 ppm Pb, 50 to 1180 ppm Zn, and traces of gold. PDH 8 returned 12 to 160 ppm Cu, 4 to 52 ppm Pb, 36 to 640 ppm Zn, traces of gold, and trace to 1.0 g/t Ag.

DRILLING - Two deep percussion holes were put down in an area of alteration, pyritisation and anomalous Se-Te. The first hole (PDH 7) was put down to test for the presence of BMS, and intersected 40 m of pyritic "fine acid" volcanic rock before passing into coarse quartz-feldspar porphyry of the UMP. The hole was extended by diamond drilling as DDH 63/7 from 248 to 420 m. It penetrated coarse quartz-feldspar porphyry of the UMP for its entire length. The lack of intersection of the BMS suggests that in this area the BMS may be dipping more steeply than anticipated. No significant sulphides were intersected except for the disseminated pyrite in the upper part of the percussion drill hole. The second percussion hole (PDH 8) intersected 56 m of pyritic "fine acid" volcanic rock before passing into coarse quartz-feldspar porphyry of the UMP. No significant sulphides were intersected apart from the disseminated pyrite in the "fine acid" volcanic rock.

3) Mine Corridor South

GEOCHEMISTRY - Material from DDH 59/1 returned 30 to 995 ppm Cu, 5 to 180 ppm Pb, 70 to 1400 ppm Zn, and trace to 0.6 g/t Ag. Material from DDH 59/2 was assayed. A skarn zone with about 20% pyrite from 160.8 m to 161.0 m yielded 2680 ppm Cu, 2.4 g/t Ag, and 396 ppm Zn. A second pyritic skarn zone from 327.24 m to 328.24 m yielded 2.0 g/t Ag, 1180 ppm Cu, and 348 ppm Zn. No other significant values were recorded.

DRILLING - Two holes were put down by the Queensland Depart of Mines under 50% subsidy arrangement with Geopeko. The first hole (DDH 59/1) was put down in the N part of the area. The hole penetrated UMP to 217.65 m, at which point it intersected the Mount Morgan Tonalite. No significant mineralisation was found. The second hole (DDH 59/2) was located 500 m SE of the first hole. The hole penetrated UMP with a large proportion of intrusive rocks (latites & andesite dykes) to a depth of 304.0 m, at which depth an interbedded sequence of chert, weak jasper, minor skarn beds, and tuffaceous rocks was intersected. The interbedded sequence would appear to be the equivalent of the BMS in a much diminished form. As a host for a Mount Morgan-type orebody, its potential would appear to be considerably diminished, as suggested by its lesser thickness and the almost complete absence of jaspers. This sequence terminated with a major skarn zone from 438.6 to 445.2 m. The hole continued in coarse fragmental and tuffaceous rocks (the LMP) to its final depth of 546.68 m. Two zones of minor mineralisation occurred in the hole.

4) Upper Nine Mile Creek area (UNMC) - 11 km ESE of Mount Morgan in the headwaters of Nine Mile Creek. The area was partly investigated as the Mount Warner area. Exploration is focused on a major copper-zinc geochemical anomaly found previously.

GEOLOGY - The rocks are the part of the Capella Creek beds that are locally known as the Moongan Rhyolite. The volcaniclastic sequence is characterised by a continuous sedimentary horizon comprising jasper, manganiferous siltstone, banded chert and minor intraformationally folded crystal tuffs called the Manganese Marker. Above this marker are massive, flow banded fragmental and lithic tuffs of rhyo-dacitic composition, ash tuffs, crystal tuffs, and fine acids. To the S appears a rhythmically bedded chert-siltstone-ash tuff unit 200 m above the Manganese Marker. Underlying the Manganese Marker is the sequence of rocks termed the Bedded Formation which includes a substantial fine acid unit and a chemical sediment zone of fossiliferous limestone and chert. This formation contains the bulk of the mineralisation known in the area. The Bedded Formation consists of layered rhyolitic ash tuff, crystal tuff, and jasper-chert-chloritic siltstone lenses and beds. Below this predominantly sedimentary zone are lithic-lapilli and rounded fragmental tuffs which pass downwards into banded pyritic chlorite-rich argillaceous rocks with minor pyritic quartz lithic tuffs, commonly with a jaspery matrix. A gradational change marked by decrease in Fe and Mn staining, increasing clastic fragment size and scarcity of bedded fine grained sediments, signals the appearance of the lower most unit named the Footwall Tuffs. These massive fragmentals and agglomeritic quartz-chlorite-rich rocks form rugged outcrops and extensive scree deposits. Correlating to the S with the Mt Dick Fragmentals, these rocks form a basal volcanic pile over 500 m thick, extending over a strike length of at least 7 km. Intruded into the UNMC sequence is a narrow, transgressive sill of medium grained feldspar porphyry which has a magnetic character. Numerous narrow basic dykes occur but are seldom seen on the surface. From the initial work done on the prospect, two areas of economic significance were located. The first is a lens of barite rich (up to 22% BaSO4) agglomerate stratigraphically above a hematitic-pyritic siltstone horizon in the bedded formation. The second, in Springs Creek, is an exposure of sheared fragmentals, cleaved chloritic siltstones, baritic gossan, and cryptocrystalline pyritic cherts sitting above the Footwall Tuffs which are in this area strongly chloritic and Fe and Mn stained. Old shallow diggings are concentrated on the sub-outcrops of the gossan.

GEOCHEMISTRY - A grab sample from the second area of interest returned 3% Pb and 6.5% Barite. Rock chip sampling of the units exposed revealed the presence of high levels of copper, lead, and zinc in the Manganese Marker (averages of 334 ppm Cu, 157 ppm Pb, 502 ppm Zn, 4.3% Mn, 51 ppm Ba, and 1 ppm Ag), Bedded Formation (averages of 1468 ppm Cu, 150 ppm Pb, 184 ppm Zn, 615 ppm Mn, 203 ppm Ba, 4 ppm Ag), and altered Footwall Tuffs (averages of 106 ppm Cu, 54 ppm Pb, 549 ppm Zn, and 2063 ppm Mn). The gossans from the northern area returned averages of 898 ppm Cu, 817 ppm Pb, 1827 ppm Zn, and 1369 ppm Mn.

Analysis of the material from the hand augering has revealed 3 main centres of metal concentration. Five soil geochemical anomalies are related to the Bedded Formation, both at its lower contact with the Footwall Tuffs and along the top contact with the Manganese Marker. Anomaly 1 is situated on the barite zone which overlies banded pyritic sediments. The results reach 1600 ppm Pb and 400 ppm Cu; zinc forms a diffuse high over the Bedded Formation and silver occurs as a distinct anomaly above 4 ppm associated with the barite zone. The second major zone of high soil geochemistry (Anomalies 2 & 3) occurs on the S part of the grid in the Springs Creek area, and is open to the S. The results reach 1100 ppm Cu and 450 ppm Pb; zinc forms a broad high zone with values above 240 ppm. The barium soil geochemistry correlates with the base metal anomalies. Anomaly 4 is within the Bedded Formation and contains maximums of 185 ppm Cu, 160 ppm Pb, 3100 ppm Zn, 4 ppm Ag, and 3812 ppm Ba. Anomaly 5 is within altered Footwall Tuffs and returned maximums of 860 ppm Cu, 480 ppm Pb, 3500 ppm Zn, 2 ppm Ag, and 1000 ppm Ba.

Material from the drilling of PDH 1 returned an intersection of 6-18 m with 0.45% Zn and 2 g/t Ag. PDH 2 returned no significant results except for 3000 ppm Zn in chert-jasper. PDH 3 returned 6 m with 12 g/t Ag. PDH 4 returned no significant results. PDH 5 returned values up to 1% Zn, 0.5% Cu, 6 g/t Ag, and 1.4% Ba. PDH 6 recorded no values of interest. Analysis of core from DDH 77/1 returned 62- 70 m with 0.83% Zn; 94-98 m with 1.4% Zn; and 56-74 m with 0.31% Ba. Analysis of material from DDH 77/2 returned best results of 97-108 m with 4.35% Zn, 16.5 g/t Ag, and 0.3 g/t Au; 102-107 m with 1.0% Cu; and 119-120 m with 2.24% Cu, 10 g/t Ag, and 0.45 g/t Au.

GEOPHYSICS - A SP survey identified an anomaly in the Footwall Tuffs. An IP survey was initiated in order to focus on zones of concentrated sulphide mineralisation. The results show four narrow linear, strike conformable anomalies and are designated Anomaly A, B, C, and D. Anomaly A is in Springs Creek, Anomaly B is in the Footwall Tuffs, Anomaly C is adjacent to the SP anomaly, and Anomaly D is located in the Hanging Wall Tuffs. A resistivity survey revealed highs on the Footwall and Hanging Wall Tuff units. A resistivity low forms a cross-cutting trend, and is adjacent to IP Anomaly A. A TURAM (EM) survey identified small anomalies forming a definite linear zone trending parallel to strike within the Bedded Formation.

DRILLING - Hand auger drilling was carried out to collect B-horizon soil samples. Percussion drill holes PDH 1, 2, and 3 were drilled to test geochemical anomaly 2, and reached depths of 58, 50, and 80 m respectively. PDH 1 was extended with diamond drilling (DDH 77/1). DDH 77/1 intersected the down dip extension of the outcropping barite zone and the banded chloritic pyrite zone containing zinc mineralisation before passing into chloritic fragmental tuffs containing disseminated sphalerite and pyrite. PDH 4, 5, and 6 were drilled to test the Springs Creek area, and reached 49, 45, and 21 m respectively. The Queensland Department of Mines drilled a deep stratigraphic hole (DDH 77/2) in IP Anomaly A. The hole reached 278.74 m and intersected zones of significant mineralisation. The mineralisation consists of sheared bands of fine grained pyrite and sphalerite (white) in foliated chloritic-quartz lithic tuff, massive banded pyrite with blebs of chalcopyrite in a siliceous gangue. The lower intersection occurs as contorted pyrite-chalcopyrite bands up to 10 cm thick and quartz- chalcopyrite veins in a foliated black chlorite rock.

5) Ajax Mine area - 23 km SE of Mount Morgan

GEOPHYSICS - The result from the EM survey were received. The results revealed a small discrete anomaly associated with the known mineralisation and a number of larger anomalies. Some of the other anomalies are associated with observations of alteration and pyritisation.

DRILLING - Diamond drill hole, DDH 47/8, was designed to test beneath the old mine workings at a depth of 250 m. The hole cored altered rhyolitic fragmentals, pyritic chert, and metavolcanics for its total length of 326.8 m. The zone of alteration in this hole was much larger than in the previous holes put down, although zinc values were very much lower.

6) Fab Prospect - 20 km SE of Mount Morgan

GEOCHEMISTRY - The interval 98 to 116 m from PDH 5 returned 602 ppm Pb, 1320 ppm Zn, and 1640 ppm Mn. Core from PDH 6 returned maximums of 204 ppm Cu and 3760 ppm Zn.

GEOPHYSICS - A magneto-metric resistivity survey was carried out. The results indicate the presence of a conducting horizon from 60 to 150 m wide, running N-S through the prospect, parallel to strike, for a distance of 1700 m. Three discrete anomalies with a strike length of about 300 m each occur within the conducting horizon. The S anomaly is adjacent to a narrow SP anomaly and associated with a weak zinc-copper soil anomaly. The central anomaly associated with some spot high soil geochemistry (up to 2200 ppm Zn and 330 ppm Cu) but occurs partially below a cover of river gravels. The N anomaly is the largest of the three, and occurs completely below thick cover (3-10 m) of river gravels. Drilling revealed that the conductive horizon is caused by the pyrite-rich layers.

DRILLING - 3 percussion drill holes were put down, two of which were designed as precollar holes for diamond drilling. The first hole, PDH 5, reached 148 m and penetrated a sequence of quartz-biotite- cordierite-amphibole hornfels with minor intervals of pyrite-biotite schist. Trace amounts of chalcopyrite were observed from 44 to 54 m, and the interval from 98 to 116 m carried 8% pyrite. PDH 6 reached 51.8 m, was drilled on the central MMR anomaly and was used as a precollar hole for diamond drilling which reached 232.0 m. The diamond drilling cored highly pyritic siliceous hornfelsed rock. Apart from its higher grade of metamorphism, the rock is virtually identical with the pyritic quartz-feldspar porphyry occurring adjacent to the Sugarloaf orebody. PDH 7 was designed as a precollar hole for diamond drilling, but the diamond drilling was not started. Up to 15% pyrite was logged in the chip cuttings.

7) Grillo Hill Prospect - 16 km ESE of Mount Morgan.

GEOLOGY - The area consists of an extensive zone of pyritic sericite-clay alteration within a thinly bedded, nearly flat-lying sequence of acid lithic fragmental rocks and cherts.

GEOCHEMISTRY - Soil sampling was completed. Copper values show two highs associated with the exposed alteration zone. A low order lobe of copper values appears to be associated with a dolerite intrusive in the N of the grid. Lead values are not associated with the copper, but occur in a discrete zone in the SW part of the grid. Maximum value for lead was 240 ppm. Zinc values are spread widely, occurring both over the lead anomaly and the copper anomaly, excepting for a discrete "hole" in the centre of the NW anomaly, which is coincident with that copper high.

GEOPHYSICS - An IP survey was carried, out returning a complex pattern of resistivity highs and lows over the alteration zone.

8) Raspberry Creek area - This area is 14 km SE of Mount Morgan, and is the along-strike extension of the Upper Nine Mile Creek area.

GEOCHEMISTRY - Soil sampling revealed a large, broad copper anomaly with values over 50 ppm occupying two distinct zones within a large area above 25 ppm Cu. The N zone is a linear anomaly with a strike length of 1 km and width up to 200 m, and contains a core with up to 200 ppm Cu. This anomaly sits just above the bottom contact of the pyritic acid volcanics with the underlying Mt Dick Fragmentals, but below the continuous, well bedded manganese siltstone horizon. The S anomaly has a diffuse, irregular pattern and overlies the manganese siltstone. This anomaly is like the footwall zone to the N, open ended to the E. Lead values, like copper, form a broad, long, irregular anomalous zone. There is good correlation between zones of >20 ppm Pb, and outcrops of pyritic rocks. The footwall fragmentals, hanging wall tuffs, and fine acids contain value all below 20 ppm. There are two distinct lead highs over 40 ppm Pb. The N one has the highest value of 500 ppm Pb. This lead high is displaced relative to the copper high by 400 m to the E. The other significant lead high has a maximum of 310 ppm Pb, is an elongate irregular zone, up to 400 m wide, and it is open ended. Zinc values are low throughout the grided area with the highest value being 600 ppm Zn.

SUMMARY:

LOCALISED EXPLORATION/PROSPECTS

1) Upper Nine Mile Creek area GEOLOGY - The sequence within the grid is dipping moderately SW. The lowermost rock unit on the grid is the Footwall Tuffs, comprising coarse fragmental and agglomeratic quart-chlorite-rich rocks. These rocks occur along the Dee Range for a strike length of over 7 km. The rocks are characterised by very coarse fragments of varying lithologies, including chert, quartz-feldspar porphyry, and chloritic rocks, all in a chloritic tuffaceous andesitic matrix. No significant fine-grained sediments occur within this unit. Overlying the Footwall Tuffs is the "Bedded Formation", which consists of an interbedded sequence of layered rhyolitic ash tuff, crystal tuff, jasper-chert-chloritic siltstone, and lithic lapilli tuffs. Jasper or hematitic siltstone occurs sporadically within the unit, and some stratiform sulphides have been found in drill core. Certain chloritic schist beds occur which are usually highly cleaved. In the N part of the area a "fine acid" volcanic rock occurs (probably an ash tuff or fine quartz-feldspar porphyry) together with a zone of limestone and chert. The Bedded Formation is about 200 m thick. At the top of the Bedded Formation is a distinctive unit of manganiferous hematitic siltstone and jasper about 10 m thick. This unit is called the "Manganese Marker" and is traceable for over 10 km in the area. Overlying the Manganese Marker is a sequence of massive and banded fragmental and lithic tuffs of rhyodacite composition. A sill of magnetic andesitic feldspar porphyry intrudes the sequence.

DRILLING - DDH 77/2 was originally described in CR 7230, but more detail was given in this report. The hole was collared in the Manganese Marker. It passed into banded rhyolitic tuffs of the Bedded Formation at 22 m. The Feldspar Porphyry sill was intersected from 73-83.6 m. From 83.6 to 88.3 m, the characteristic banded cherty-tuffs continued. At 88.3 m, pyrite began to appear both in cherty rocks and as disseminations in the matrix of fragmental rocks. Small stratiform pyrite layers began to appear in the rock, particularly in cherty units, e.g. at 92-93 m. At one point several 1 cm beds of banded jasper were associate with banded pyrite in cherts within a few centimetres of each other in the core. At 97.0 m, zinc mineralisation in the form of very light-coloured white-grey sphalerite (iron-poor) appeared in sub-ore grade amounts. The sphalerite is variable, occurring as discrete zoned crystals in tuffaceous or chloritic rock and also as thin massive zones, or banded pyrite-sphalerite with blebs and veinlets of chalcopyrite in a siliceous gangue. From 108 m, sphalerite gradually decreases in the hole but chalcopyrite continued at a low level, usually less than 0.5% Cu, but reaching a value of 2.24% in a sheared chloritic zone from 118.7 to 119.7 m. The host rocks continued to be banded quartz-feldspar crystal-lithic tuffs and chloritic zones. Mineralisation generally decreases gradually, and dropped considerably after 134 m, though still carrying anomalous geochemical values. A zone of massive hematite-chlorite rock with minor sulphides forms a marker unit near the base of the Bedded Formation, which is considered to be at 172 m in the hole. From 172 m to the end of the hole at 278.74 m, the rocks consist of barren dacitic footwall tuffs. These rocks are distinct from the Bedded Formation and represent the unmineralised basal part of the sequence.

2) Hamilton Creek area GEOLOGY - A large, intensely altered and pyritic zone occurs in rocks of the (?) Capella Creek beds immediately S of a block of the Mine Corridor rocks. The (?) Capella Creek beds in the area consist predominantly of intermediate lithic tuff, feldspar porphyry, and minor limestone. The Corridor rocks in the area consist mainly of fine quartz-feldspar porphyry. A limestone bed occurs within the Corridor rocks. The Capella Creek beds in the area are gently folded into a S-plunging anticline in the area of the alteration zone. The anticlinal structure is more or less concentric with the occurrence of the Corridor rocks, which appear to be a faulted-in block. This block is suggestive of a domal structure, although no dome can be defined on present information. The alteration zone consists mainly of a clay mineral with lesser amounts of calcite, sericite, and chlorite, with pyrite up to about 8% in places. The alteration crosses the stratigraphy. Several relatively minor faults cut across the area. The Dee Volcanics occurs on the W side of the grid, but its contact with the underlying Capella Creek beds is uncertain owing to similarity of lithological types and lack of fossil evidence.

GEOCHEMISTRY - Material from the percussion-drilled part of DDH 32/11 returned 12 to 136 ppm Cu, 8 to 70 ppm (with one high of 300 ppm) Pb, 36 to 220 ppm Zn, and traces to 1.2 ppm Ag. The results from the cored part of the hole were 5 to 230 ppm Cu, 10 to 30 ppm Pb, 5 to 380 ppm Zn, and <1 to 2 ppm Ag. Skarn and granitised rocks where present showed slightly higher values than intrusive rocks. None of these values are significant with respect to mineralisation, tending to reflect variations in rock geochemical background.

DRILLING - Drilling in the area showed that the alteration zone is intense and extensive, but has only low base-metal geochemical values. Diamond drill hole DDH 32/11 was sited on the westernmost of two intense centres within the zone, more or less on the axis of the poorly defined S-plunging anticline. The hole was precollared to a depth of 198 m, intersecting intensely altered siliceous rock (possibly silicified rather than originally siliceous) for the entire length. The rock contained of the order of 10% pyrite throughout. The diamond drill core began to show some lithological variation. The rock became more fragmental and although still intensely altered, could be recognised as similar to the quartz- feldspar porphyry tuffs of the UMP. Small dykes of pyritic microgranite intrusions began to appear after 205 m. These microgranite intrusions became larger with depth in the hole, and showed a clear relationship with alteration. The host rock is gradually granitised with depth, showing a clear gradation between ungranitised quartz-feldspar porphyry tuff, through epidotised and partially granitised tuffs, to granitised rocks with relict fragmental textures (238.5 to 322.67 m). The alteration assemblage associated with the microdiorite intrusive is clearly superimposed upon the granitisation assemblage. Lower in the hole all granitisation textures disappear and a "cleaner" intrusive granodiorite phase apparently intrudes the granitised (syenitic) host rock, e.g. 403.7-404.2 m. From about 381.8 m onwards, the entire assemblage of rocks shows a complex pattern of brecciation which is thought to be a "roof-breccia" assemblage typical of the margins of some porphyry coppers. This assemblage consists of large fragments (>10 cm) of both altered syenitic host rock and less altered microgranite intrusive, both of which appear to have been further altered. From about 512 m to the end of the hole at 550.6 m the rock consists of relatively homogeneous hornblende syenite, which appears to be the last intrusive phase in the area apart from some minor late dykes.

3) Mine Corridor South - This drilling was already covered in CR 7230.

SUMMARY:

LOCALISED EXPLORATION/PROSPECTS

1) Upper Nine Mile Creek area

GEOCHEMISTRY - Analysis of material from PDH 9-DDH 77/3 returned only one significant interval, 204.5-205.0 m, which yielded 1.57% Zn. Analysis of material from PDH 10-DDH 77/4 yielded 0.21% Cu and 0.39% Zn from 66 to 70 m. The interval of 48 to 52 m from PDH 11 returned 0.27% Zn. Analysis of material from PDH 12-DDH 77/5 returned 1.17% Zn from 130 to 133 m, and <0.5% Cu from 133 to 142 m. Assay of material from PDH 13-DDH 77/6 returned 0.78% Cu from 241 to 242 m. Analysis of material from PDH 14-DDH 77/7 returned 23.4 g/t Ag from 111 to 132 m, and 125.5 g/t Ag, 0.51 g/t Au, 1.8% Zn, 0.5% Pb, and 0.15% Cu from 152.9-163.6 m.

DRILLING - Two percussion drill holes were put down prior to the major diamond drilling program. PDH 7 was drilled to 105 m as a precollar hole for future diamond drilling. No mineralisation was intersected in the hole. PDH 8 was designed to test a sharp IP anomaly within the Manganese Marker horizon. The hole was drilled to a depth of 103 m without intersecting mineralisation. The hole was cased for diamond drilling at a later stage. The major program of drilling which followed this was a pattern of holes around the intersection made previously in the Mines Department drill hole DDH 77/2. The first hole, PDH 9-DDH 77/3, was designed to intersect the mineralisation horizon at 120 m down dip from the previous intersection. The percussion part of the hole was collared in the Manganese Marker (to 113.0 m), then intersected a jasperous horizon (to 122 m), the Bedded Formation (to 130 m), and passed into coarse porphyritic magnetic dyke. The hole was cased and diamond drilling commenced. The hole passed out of the dyke at 143.7 m, and penetrated the Bedded Formation to 264.3 m. Fine grained sphalerite and pyrite are present as thin bands in a crystal lithic tuff in the interval 204.5-205.0 m. After this, PDH 10-DDH 77/4 was designed to test the strike extension of the mineralised horizon to the S at a depth of 70 m. The hole was collared in the Manganese Marker and passed into the Bedded Formation at a depth of 8 m. At 40 m, the hole intersected a magnetic hornblende feldspar porphyry intrusive and then passed back into the Bedded Formation at 56 m. The hole was diamond drilled from 76 m and was stopped in Bedded Formation at 147 m. The final 8 m of core is characterised by quartz-hematite zones. Minor mineralisation was intersected over a 4 m interval from 66 to 70 m. The strike extension of the mineralisation to the N was tested by PDH 11 which was collared in the Bedded Formation and expected to intersect the mineralisation at 80 m. The hole passed into the footwall at 97 m and stopped at a depth of 130 m. Minor sphalerite was noted from 48 to 52 m. PDH 12-DDH 77/5 was designed to test the extension of the mineralised horizon down dip from PDH 11. It was collared in the Manganese Marker and penetrated 26 m before entering the Bedded Formation. Diamond drilling began at 53.2 m. At 61.4 m, the hole entered a feldspar hornblende porphyry intrusive and then passed back into the Bedded Formation at 80.2 m. The hole passed into the Footwall Tuffs at 191 m, and the hole was ended at 207.1 m. Disseminated sphalerite and fine grained pyrite were noted from 130 to 133 m and sporadic disseminated chalcopyrite occurred from 133 to 142 m. PDH 13-DDH 77/6 was designed to test the mineralised horizon down dip from DDH 77/4. The hole was collared in the Hanging-Wall sequence, passed into the Manganese Marker at 64 m, and entered the Bedded Formation at 124 m. Diamond drilling commenced at 201.5 m, and penetrated the Footwall Sequence at 287.85 m. Disseminated chalcopyrite was noted from 241 to 242 m, and the lowermost 10 m of the Bedded Formation is characterised by quartz-hematite zones. PDH 14-DDH 77/7 was designed to test down dip from 77/1. The hole was collared in the Hanging- Wall sequence, entered the Manganese Marker at 20 m, passed into the Bedded Formation at 31 m, and entered a zone with significant pyrite at 106 m. Diamond drilling commenced at 108 m and finished at 253 m without leaving the Bedded Formation. Sub-massive pyrite was intersected from 111 to 132 m, and massive to semi-massive pyrite and sphalerite bands from 152.9 to 163.6 m. The down dip extension of the mineralisation in PDH 14-DDH 77/7 was tested by PDH 15-DDH 77/8. The hole was collared in the Hanging-Wall sequence, and diamond drilling commenced at 81 m. The hole entered the Manganese Marker at (?)91 m, passed into the Bedded Formation at (?)101 m, and entered the Footwall sequence at 446.5 m. The hole was stopped at 545.1 m. Disseminated pyrite and pale yellow sphalerite occur in tuffs from 384 to 430 m.

2) Upper Raspberry Creek area - approximately 20 km SE of Mount Morgan. This area is the along- strike extension of the Upper Nine Mile Creek and Raspberry Creek areas.

GEOLOGY - Units outcropping are a strike continuation of the Bedded Formation. Units strike between 110 and 120° and dips vary from horizontal to about 60° to the SW. Stratigraphically, the lowermost unit of the grid is a pyritic rhyolite tuff which is overlain by a sub-gossanous sericitic and limonitic zone. Overlying the pyritic tuffs is a sequence of manganiferous horizons consisting of siltstone, jasper, chert and interbedded pyritic and non-pyritic, rhyolitic lithic and crystal-lithic tuff and breccia. The uppermost rhyolitic lithic tuff of this group is immediately overlain by a geochemically anomalous magnetic, sulphide-rich manganiferous chert-siltstone unit known locally as the Yarrawonga bed. This horizon is open to the E, and thickens towards the Dee Range. Rhyolitic tuff, lava breccia and ignimbrite overlies the Yarrawonga bed, and are in turn overlain by a jasper horizon which marks the uppermost limit of the sequence of rocks considered equivalent to the Bedded Formation at UNMC. The Bedded Formation at Upper Raspberry Creek is overlain by chloritic, calcareous and fossiliferous fragmental tuff, agglomerate, and intermediate ash tuff. Dolerite and feldspar porphyry sills have intruded the sequence and some transcurrent faulting is evident.

GEOCHEMISTRY - B-horizon soil samples were collected and assayed. Copper defined two large anomalies with core values in excess of 200 ppm, and a number of smaller anomalies have values exceeding 100 ppm Cu. These anomalies occur within a large area of above background copper values. The W anomaly is open to the W, has a maximum value of 295 ppm Cu, and occurs near the stratigraphic top of the Bedded Formation. The E anomaly is open to the NE, has a maximum value of 320 ppm Cu, and overlies the Yarrawonga bed. Lead values define an irregular, broad zone of anomalous values over 40 ppm Pb which extends over much of the N part of the Upper Raspberry Creek grid. It contains a number of discrete highs above 80 ppm and two significant zones with values in excess of 160 ppm. The W anomaly is open to the E, has a maximum value of 250 ppm Pb, and lies above a manganiferous sedimentary horizon. The E anomaly is open to the N, has a maximum value of 290 ppm Pb, and is coincident with the copper anomaly over the Yarrawonga bed. Zinc values were low throughout the area. An elongate anomaly with a maximum value of 230 ppm Zn was defined. Several small zinc anomalies correlate with the lead and copper anomalous zone over the Yarrowonga bed. The highest zinc value on the grid is a spot high of 340 ppm Zn which lies over a manganiferous siltstone horizon. Silver values are uniformly low over the grid. High silver (3 ppm Ag) is noted to correlate with the anomalous Cu, Pb, and Zn over the Yarrawonga bed. Manganese values clearly differentiate the Hanging Wall tuffs on the S side of the grid. Values above 1000 ppm are usually coincident with manganiferous rocks, e.g. the Yarrawonga bed or any of the manganiferous jasperous siltstone horizons. The intrusive dolerite horizon also yielded manganese values over 1000 ppm, as did any of the areas of observed pyritisation.

SUMMARY:

LOCALISED EXPLORATION/PROSPECTS

1) Upper Nine Mile Creek area (UNMC)

GEOCHEMISTRY - Material from drill hole PDH16/DDH77/9 returned 130 ppm Cu and 360 ppm Zn between 141 and 150 m. The "crenulated cherty tuff" sequence from PDH17/DDH77/10, PDH18/DDH77/11, and PDH19/DDH77/12 was assayed. DDH77/10 intersected 10 m of 1.4% Zn associated with a limestone unit. DDH77/11 intersected 16 m of 0.8% Cu beneath a limestone unit and associated with the hematite marker bed which is usually near the base of the "crenulated cherty tuff". DDH77/12 intersected 11 m at 7.3% Zn beneath the limestone bed, with some 1 m intervals reaching values over 20% Zn. Analysis of material from the "crenulated cherty tuff" sequence in PDH20/DDH77/13 and PDH21/77/14 returned maximum values of 2.5% Cu over 1 m, and 7.6% Zn over 2 m. The mineralised horizon in DDH77/15 yielded 6.2 m of 7.1% Zn and 6.4 g/t Ag, with 2 m averaging 3.3% Cu.

DRILLING - The hole PDH16/DDH77/9 was put down to test the extension of the Springs Creek geochemical anomaly. The hole collared in Manganese Marker, and drilled through the Bedded Formation to 150 m. From 150 to 190.8 m the hole intersected the crenulated cherty tuff unit, then entered the Footwall Sequence and was terminated at 209.6 m. The only mineralisation was pyritic material between 141 and 150 m. Small highly pyritic chloritic beds were intersected lower in the hole but contained no significant values. Three holes (PDH17/DDH77/10; PDH18/DDH77/11; and PDH19/DDH77/12) were put down adjacent to PDH 14-DDH 77/7. All holes collared within or above the Manganese Marker horizon (about 10 m thick). They then drilled through an approximately 90 m thick sequence of variable ash tuffs (usually andesitic and granular), with minor chert, jasper interbeds, and limestone. The holes then intersected a 50 m thick, homogenous, quartz-feldspar crystal-lithic tuff. This was followed by approximately 10 m of fine banded chert and minor sulphides, usually fine stratiform, but sometimes semi-massive. Beneath this is a characteristic laminated crenulated cherty tuff unit which has a contorted slumped appearance with a variable thickness. All three holes bottomed in the Footwall Sequence. Each hole intersected mineralisation in the "crenulated cherty tuff". A further two holes (PDH20/DDH77/13 and PDH21/77/14) were put down adjacent to PDH 14-DDH 77/7. The holes collared in or above the Manganese Marker and penetrated a 75 m section of variable ash tuffs with minor jasper and limestone. A pyritic tuff zone, 3 to 5 m thick, marks the top of the massive quartz-feldspar crystal-lithic tuff zone (pyritised in DDH14, but barren in DDH 13). A pyritic bed with high silver occurs near the base of this tuff and is underlain by Zn-Ba rich zones lower in the holes. The massive quartz-feldspar crystal-lithic tuff is 55 m thick. The "crenulated cherty tuff" unit is approximately 95 m thick in these two holes, and both holes intersected narrow beds of mineralisation associated with limestone. The holes were terminated before the footwall rocks were reached. Two holes (PDH23/DDH77/15 and PDH24/DDH77/6) were put down to follow the mineralisation intersected in DDH77/12. DDH77/15 intersected an approximately 90 m thick "crenulate cherty tuff" unit containing the mineralised horizon, but DDH77/16 intersected almost no mineralisation at all. Three percussion holes (PDH 22, 25 and 26) were put down in the Springs Creek area to test an IP anomaly. PDH 22 was placed too far to the E and reached only 30 m depth before entering the Footwall Sequence. PDH 25 tested the modified target and intersected the mineralised horizon which carried sufficient sulphides to account for the IP anomaly. PDH 26 was put down to test the E extension of the IP anomaly but did not intersect any mineralisation.

2) Mount Dick area - extension of the grid between Raspberry Creek and UNMC.

GEOCHEMISTRY - Rock chip sampling was carried out over the grid. Copper showed low anomalous values on the S flank of the silicified zone and the jasperous area. Slightly higher but only moderately anomalous values of copper occur along the manganiferous siltstone horizon. Lead values identify a discrete anomaly occurring on the manganiferous siltstone horizon. Anomalous zinc values occur both on the jasperous zone and on the manganiferous siltstone, reaching values of 580 and 680 ppm Zn respectively. Anomalous trends up to 700 ppm Zn also occur in the footwall rocks on the N of the grid. Manganese showed a pronounced high in the manganiferous siltstone, reaching values of over 1%. Silver returned no significant results, and barium showed no obvious trends.

3) Raspberry Creek/Upper Raspberry Creek area GEOCHEMISTRY - Soil sampling was begun, but the results are not yet available.

4) Ajax Mine area GEOCHEMISTRY - Of the first three percussion drill holes (PDH 25, 26 & 27), PDH 27 returned the best intersection, yielding 14 m averaging 7.98% Zn, 0.87% Pb, 0.23% Cu, 40.4 g/t Ag, and 0.36 g/t Au. The mineralisation in PDH 43 returned 1.22% Zn, and the mineralisation in PDH 31 returned 1.69% Zn with some Cu, Pb, and Ag. The mineralised zone in PDH 38 returned 2.5% Zn, and the mineralised zone in PDH 36 returned 6.45% Zn. PDH 42 returned 22.7 g/t Ag, and 0.4 g/t Au.

DRILLING - A program of percussion drilling was carried out. The holes PDH 25, 26, and 27 were the first to be put down, and were designed to test for trends in the mineralisation intersected in DDH4. The results indicate a shallower dip to the W for the mineralisation, and confirm that the nature of the mineralisation is patches of zinc with minor values of copper and gold. The mineralisation remains open at depth. PDH 28, 29, 31, and 43 were put down to test the mineralised zone on either side of Ford's shaft. PDH 28 apparently did not reach the mineralised horizon; PDH 29 & 43 drilled into old workings, presumably connected with a small shaft W of Ford's shaft; PDH 43 intersected 9 m of mineralisation; and 31 intersected 17 m of mineralisation. PDH 30, 32, 33, and 35 were put down to test the area either side of where DDH 3 had been drilled. PDH 38 and 36 intersected 3 m and 20 m of mineralisation respectively. PDH 42 was put down on the peak Cu-Pb anomaly and yielded 9 m of mineralisation.

SUMMARY:

LOCALISED EXPLORATION/PROSPECTS

1) Upper Raspberry Creek area

GEOLOGY - The sequence is the same for the UNMC area, with the Footwall Volcanics (sugary ash tuffs which are variably fragmental and are characterised by fine chloritic shards of fiamme), Bedded Formation (interbedded quartz-feldspar crystal-lithic tuffs and cherty rocks, some of which are jasperous and manganiferous), Hanging-wall Sequence (quartz-feldspar crystal-lithic tuff which has gradational variations down to sandstone and siltstone, and the Andesite Sequence (fine feldspar porphyritic andesite lava, but often contains thinly bedded cherts and andesitic to dacitic lithic lapilli tuffs.

GEOCHEMISTRY - The results of the soil sampling from the previous year were received. The altered Footwall Volcanics display low-order anomalous values of copper, lead, and zinc (maximums of 345 ppm Cu, 500 ppm Pb, and 535 ppm Zn). The Bedded Formation shows weakly anomalous trends in copper (60 to 295 ppm Cu), lead, and zinc (maximum of 250 ppm Zn) coincident with manganiferous beds, but no pronounced anomalies are present.

2) Mount Hopeful area - Adjacent to the Upper Raspberry Creek area.

GEOCHEMISTRY - Soil sampling was carried out. Copper defined a weak zone trending along the top of the range (peak of 290 ppm Cu), corresponding with a manganiferous siltstone horizon. Lead values shows the same zone as copper, and peaks at 290 ppm Pb. Zinc values further define the trend at the top of the range, and show that it extends down the E slope of the range as marginally anomalous values between 100 and 200 ppm.

3) Fern Hills area

GEOLOGY - In the SW corner of the grided area is a sequence of andesitic tuffs which probably represent the basal part of the Capella Creek beds. These may be unconformable on the predominantly acid volcanic rocks in the rest of the grid. The acid volcanic rocks are a series of ferruginous and cherty ash tuffs, usually siliceous but quite variable. In some places these are well-bedded and contain stratiform pyrite. Some of these bedded rocks contain jasper and manganese, and are considered to be the equivalent of the Bedded Formation of the Moongan Rhyolite sequence in the UNMC and Raspberry Creek area. Beneath these bedded rocks is a sequence of massive andesitic fragmental rocks. Thin section work suggests that the rock is in part a chloritised acid volcanic rock rather than an andesitic rock. The lower part of this unit is fine-grained (lapilli tuff) and contains apparent fragments of sulphides, mainly sphalerite. Although sub-ore grade, these sulphides is of the style which could occur in the peripheral environment of a major BMS deposit. Beneath the andesitic fragmental rocks is a sequence of ferruginous ash tuffs and some andesitic fragmentals which apparently represent the lowest part of the stratigraphy in the grid area. Further E, with a very irregular contact, is a variable but mainly massive hornblende andesite rock unit. The irregular nature of this unit is suggestive either of an intrusive rock or an unconformably overlying, E-dipping sequence. Within the hornblende andesite are several prominent occurrences of ferruginised, silicified rock mapped as "ferruginous ash tuff". These localised units in places appear to be tuffaceous owing to an apparent fragmental texture, but in other places show characteristic dyke-like patterns. An apparent structural break, marked by changes of lithology along strike, crosses the grid in a NE trend. The break is complex, apparently consisting of several faults and an andesitic dyke. In the NW of the grid is a major unit of weakly foliated, siliceous chloritic fragmental rock. This unit has no clear correlative with the section S of the structural break, although it may be equivalent to the "cherty ash tuff" unit. Beneath this unit is a complex andesitic tuff- ferruginous ash tuff-fragmental rhyolite unit. The "ferruginous ash tuff" may represent an intrusive unit such as that enclosed within the hornblende andesite. This unit may be equivalent to the andesitic fragmental tuff in the S of the grid. Beneath this complex unit is a hornfelsed, highly silicified, cherty ash tuff which usually carries significant pyrite.

GEOCHEMISTRY - Soil sampling was carried out. Copper values defined a zone of poorly clustered low-order anomalous values (peak of 410 ppm) in the area of the mineralised andesitic fragmental horizon in the S of the grid. A broader zone of low-order anomalous values (up to 260 ppm Cu) occurs in the NE end of the grid, mostly associated with the pyritised siliceous rock, but some are in andesite, or the intrusive "ferruginous ash tuff". Sporadic low anomalous zones occur on the E margin of the grid and on the S margin of the grid, mostly associated with the "ferruginous ash tuff". Lead values show two irregular closed clusters of low-order values centring on the mineralised andesitic tuff unit in the S of the grid. No anomalous lead values are associated with the copper zone in the N. The highest lead value was 490 ppm Pb. Zinc values tend to repeat those of copper but show a more consistent pattern, with two significant anomalous zones corresponding to the mineralised tuff in the SW and the silicified zone in the NE. Zinc peaks at 0.25% and 0.21% Zn in the two zones respectively. Manganese values are uniformly high over most of the grid (i.e. above 500 ppm). A definable zone of over 2000 ppm with a low in its centre occurs over the mineralised tuff zone.

4) Belgamba area - 8 km ENE of Mount Morgan

GEOLOGY - This area was investigated as the apparent source area for the Dee River alluvial gold deposits. A grid was surveyed to cover a lobe of acid volcanic rocks containing jasper adjacent to the Struck Oil fault in the area just SW of Bouldercombe. S of the Dee River the rocks are all andesitic (Capella Creek beds) which are apparently nearly flat lying. A series of sub-parallel strong linear features mark the boundaries of the lobes of acid volcanic rocks within the grid. These features have been identified as faults. The westernmost lobe consists of fine quartz-feldspar crystal tuff, which contains rare thin jasper beds and is weakly altered, bleached, and silicified. The central lobe is similar but is less altered with no jasper. The southernmost area of acid volcanic rocks consist of quartz- feldspar crystal ash tuff which is more chloritic and somewhat coarser. N of the acid volcanic lobes the rocks are all andesite, andesitic tuff, apparently equivalent to the andesitic tuff S of the Dee River.

GEOCHEMISTRY - The area was soil sampled. Copper values are low over the grid, with values in the andesitic rocks in the W slightly higher than values in the acid rocks on the E of the grid. Lead values are uniformly low. Zinc values are slightly higher in the W of the grid but could not be considered anomalous. The area is low in gold, returning a peak value of 15 ppb against a background of 5 ppb or less. This indicates that the acid volcanics are not the provenance of the alluvial gold. Silver values are uniformly low. Magnesium values showed no district trends, but the acid volcanic rocks tended to have a lower background for manganese.

GEOPHYSICS - A magnetic and IP survey were carried out. The magnetics revealed no discrete contourable anomalies. The local highs and sharp contrasts appear to relate to the fault zones. The andesitic rocks tend to have a higher and more erratic magnetic character than acid rocks. The only conclusive trend in the IP survey was low resistivity in alluvium. The centre of the grid shows a comparatively high chargeability, reaching a broad peak of 4%. The implications of this response are uncertain.

5) Upper Don area - 50 km SE of Mount Morgan. The grid in the area was extended to the N and SW.

GEOCHEMISTRY - Soil sampling in the S extension of the grid showed broad zones of low-order anomalous copper (50 to 200 ppm) occurring within andesite and represents background for that rock. Lead shows no significant values. Zinc shows low values reflecting the main anomalous zinc zone in the adjacent original grid on the E. Gold returned low-level values with only one spot high associated with old gold workings, and a local zone of high background in the NW corner of the grid. Silver values were uniformably low, and manganese showed a broad irregular zone corresponding very roughly with the area of andesite. Soil sampling in the N grid showed a low-order copper anomaly trending in a NW direction, with a maximum value of 330 ppm Cu in the S part of the grid. The trend correlates approximately with local zones of pyritisation and ovoid alteration within the acid volcanic rocks. Low-order lead values appear to be fringing the copper trend, but have an almost antipathic relationship in detail. The maximum lead value is 300 ppm on the E central part of the grid. Zinc values show a very broad anomalous zone peaking at 0.17% Zn and trending diagonally NW across the grid. The trend is open to the S and decreases but does not close to the N. The zinc overlaps both the lead and copper trends. Manganese values show two trends of moderate anomaly. The W trend follows the course of the river but is too broad to be a secondary anomaly. The E trend is very broad and appears to reflect the mineralisation in zinc, lead, and copper

6) Upper Nine Mile Creek area

GEOCHEMISTRY - An orientation geochemical survey was carried out using core and drill cutting material from the earlier drilling.

SUMMARY:

LOCALISED EXPLORATION/PROSPECTS

1) Upper Nine Mile Creek area

GEOPHYSICS - One SIROTEM traverse was completed in the area. Initial single loop traverses suggested a small anomaly, but later displaced loop traverse yielded no anomaly. The data for the UNMC area are not complete due to lack of time available for the survey.

2) Mount Dick area

GEOPHYSICS - Two SIROTEM traverses were carried out in the area. Both traverses displayed a clearly developed anomaly which could indicate massive sulphide mineralisation.

3) Raspberry Creek area

DRILLING - The circular anomaly was investigated by percussion-diamond drilling. Drill hole 62/2 penetrated a thick section of interbedded variable tuffaceous rocks with manganiferous jasper beds, as inferred from surface mapping. The remainder of the hole consisted of interbedded variable tuffaceous rocks including mainly "crenulated cherty tuff" with minor finely bedded chert units. Jasperous colouring appeared in the lower part of this unit and a few small jasper beds also occurred. A thin zone of ?andesite lava occurred near the bottom of the hole with the rocks adjacent being magnetite-rich quartz-feldspar crystal-lithic tuff. The lower part of the hole correlates well with the geology found up dip on the surface, but virtually no sulphides are present compared to the altered and pyritised rocks on the surface in this area. The reason for the lack of sulphides in the drill hole compared to the surface is not known. It is possible that a penecontemporaneous fault may occur between the drill hole and the surface, giving rise to a possible concentration of sulphides such as occurred associated with the penecontemporaneous fault at UNMC.

4) Upper Raspberry Creek area

GEOPHYSICS - Two SIROTEM traverses were completed, but detected only low order anomalies.

5) Fab area

GEOPHYSICS - SIROTEM traverses were conducted over the whole grid. A major anomaly which is in the appropriate position to reflect a massive sulphide body was discovered on the NE part of the grid. It is larger and broader than the anomalies in the other areas, and it has associated IP character.

DRILLING - Drill hole PDH9 - DDH69/6 was drilled to test the SIROTEM anomaly. It was collared in manganiferous siltstone which are probably equivalent to the lowermost jasper horizons from the Raspberry Creek area. It cored high-grade hornfelsed acid volcanic rocks, essentially biotite gneiss, for its total length. The top 290 m was finely bedded with beds generally moderately dipping. Lower in the hole the dips became steeper. A fine-grained skarn horizon occurred from 225-239 m. Sulphides in abundance, averaging about 10% but reaching 20%, occurred in the lower part of the hole from 290 m to the bottom of the hole at 452 m. Sphalerite appeared at 390 m but values did not exceed 1% Zn. The amount of sulphides, particularly around 290-350 m, was probably sufficient to account for both the SIROTEM and the IP character of the grid

6) Mount Hopeful area - the grid was extended over the E side of the range to tie in with the Fab grid.

GEOLOGY - The newly covered area consists essentially of the same acid volcanic sequence, consisting mainly of cherty quartz-feldspar crystal-lithic tuffs with minor interbedded jasperous units, dipping shallowly to the SW. The andesite unit was also mapped.

GEOCHEMISTRY - The grid was soil sampled. A small copper anomalous zone, peaking at 320 ppm Cu, was confirmed near the top of the ridge. Other than this, andesitic rocks tend to have a higher background than the acid rocks. Lead values were mostly uniformably low (<50 ppm Pb), with spot highs peaking at 100 ppm Pb. Also the previously defined lead anomaly was confirmed. Zinc values were below 200 ppm and are not considered anomalous. Manganese showed a pronounced trend at the approximate level of the manganiferous and jasperous siltstone, reaching values above 1% Mn. These results show no obvious or significant geochemical trends, but the area remains of interest because of its proximity to the Fab pyritic alteration zone.

7) McKnight's area - this is the NW extension of the UNMC area

GEOLOGY - The geology is the same in the UNMC area.

8) Fern Hills area

GEOLOGY - The units previously designated as "ferruginous ash tuff" appear on subsequent examination to be altered, sericitised, pyritic intrusive rocks.

GEOCHEMISTRY - The grid was extended and soil sampled to try and close off the open ended anomalous zone. The zones of copper with values above 100 ppm Cu remain open ended and appear to occur over the ferruginous (?) intrusive rocks, although some occur over the andesitic rocks as well. Lead values show no significant variations over the extended lines except for a spot high of 320 ppm Pb. Zinc values show pronounced anomalous values peaking at 0.11% Zn in the southernmost part of the area. This coincides with an area of the ferruginous (?) intrusive rock.

9) Upper Don River area - infill griding was done in areas where previously major grid extension had been put in.

GEOCHEMISTRY - Soil sampling was carried out over the new grid. Copper values from the new sampling show a weak trend continuing S across the grid from the previously defined anomaly in the N grid. Lead values are low in the N but show a pronounced anomaly of 800 ppm on the southernmost line of the grid. Zinc values show a continuing trend across the whole grid in a N-NW direction, peaking at 0.18%. Manganese values show a continuing trend of over 0.2% Mn all along the E side of the grid. The investigations in the Upper Don River area showed that the geochemical anomaly is continuous over a length of 2.5 km in this favourable acid volcanic sequence.

10) Upper Manton Creek area - the headwaters of Manton Creek immediately N of the Upper Don River catchment area. Low order anomalous copper and zinc geochemical values were recorded from the early stream sediment survey.

GEOLOGY - The oldest rocks in the area are the acid volcanic rocks which extend from the Upper Don River area. On the divide between the Don River and Manton Creek catchment areas are variable acid lithic tuffs including quartz-feldspar crystal-lithic tuff, siliceous green lithic tuffs, and fine (?) dacite flows. These rocks extend W, under outliers of sandstone thought to be part of the Dee Volcanics, to the central part of the area around a horse-shoe bend in Manton Creek. The rocks in the central part of the area are mainly variations of the siliceous lithic tuff characterised by chloritic shards (? fiamme) and a fine ashy or siliceous matrix. On the W side of the horseshoe is a prominent cherty very fine-grained ash tuff with rare feldspar phenocrysts and minor chloritic fragments. This rock has an unusual siliceous spotted alteration pattern. In the N part of the area is a zone of "acid lithic tuff" which is not as well indurated as the remaining acid volcanic rocks and weathers more deeply. On the surface it has a bumpy texture suggestive of fragments. On the SW side of the area a sequence of andesitic rocks and sediments lies unconformably above the acid sequence. These are thought to belong to the Dee Volcanics of Pond Formation. The rocks consist of a basal unit of medium to coarse-grained green volcaniclastic well-bedded sandstone, ranging up to lithic lapilli tuff. These are overlain by coarser lithic tuffs. Finer-grained sedimentary rocks including siltstone, chert, and fine sandstone also occur in this upper sequence. Fossils occur in some of these units but these have not yet been dated. Fossils from slightly higher in the sequence W of the Upper Don area yielded Early Carboniferous ages. A large area of alteration occurs in the N part of the area W of the horseshoe bend. It consists of highly silicified zones in the acid volcanic rocks which carry pyrite or gossan up to 15% but average somewhat less. Minor occurrences of secondary copper mineralisation were found in the rocks of the (?) Dee Volcanics, and one occurrence of native copper was found in a small dyke on the SE end of the area.

GEOCHEMISTRY - Ridge and spur soil sampling program was undertaken. Copper values were very low within the acid volcanic rocks, including the alteration zone. The only areas of anomalous copper (over 60 ppm Cu) were from within the (?) Dee Volcanics on the SW of the area. These are considered to reflect an erratic high copper background in these andesitic volcanic rocks, which is a characteristic feature of the Dee Volcanics. Lead values are all uniformly low. Manganese values display several zones of over 1000 ppm Mn within mainly the acid volcanic sequence. These do not correlate with any mineralisation and are considered to reflect the geological environment as in the Upper Don area.

DRILLING - hand augering was used to collect soil samples.

SUMMARY:

GEOLOGY -

REGIONAL - Goldfields Research Group-Canberra reinterpreted mapping and drill-log data and postulated a caldera margin, defined by the axis of an asymmetric anticline in the Capella Creek beds. The caldera is postulated to have dimensions of about 12x26 km. The earliest rocks in this sequence belong to the footwall sequence. It is generally a quartz-feldspar crystal-lithic tuff containing some fiamme but generally without a well defined pumice lenticle foliation. The caldera formation is a direct result of the evacuation of the magma chamber by the large volume of magma which formed the pyroclastic flow. Eruption duration would have likely been 2-3 days. Following caldera collapse a caldera lake formed within which the Banded Mine Sequence of the mine corridor and the Banded Sequence of the Dee Range area were deposited. Following the banded sequence a second caldera forming event must have occurred. The Upper Mine Porphyries of the Mine Corridor and the Hangingwall sequence of the Dee Range again exhibit features of large pyroclastic flow deposits. The location of this second caldera is not known. At least two vents have been tentatively located for the basal eruptions of the hangingwall sequence. The two main centres of "massive sulphide" mineralisation, the Mount Morgan and UNMC, occur close to vents on the postulated southern caldera margin. Mount Morgan and Mount Usher are considered to occur where the caldera margin is cut by the extremities of a ring fault system. Anomalies at Fab, Grillo Hill etc. are interpreted as minor leakages along fractures on the caldera floor. Vein mineralisation in the Mt Usher area hangingwall sequence may be related to underlying volcanogenic mineralisation in the Banded sequence.

REGIONAL EXPLORATION

GEOCHEMISTRY

- stream sediment sampling - Previous stream sediment geochemical data from various sources was re-assessed and 18 areas anomalous for Cu and/or Zn were selected for follow-up stream sediment sampling and analysis for gold. Eleven of the areas were sampled during 1983, and results are awaited.

LOCALISED EXPLORATION/PROSPECTS

1) Mount Usher - 12 km ENE of the Mount Morgan open pit. Approximately 30,000 oz gold was produced from the workings which include the Mount Usher, Caledonian, Anglo Saxon, and Victor workings.

GEOLOGY - The workings exploited two narrow sub-parallel reefs. Three levels at Mt Usher and two levels at the New Golden Cave (80 m S) were geologically mapped and sampled. Mapping at Mt Usher indicates two steeply dipping reefs separated by 8 m of barren material (? carbonate). In the New Golden Cave workings, a thin (10 cm) quartz reef occurs. Minor quartz/sulphide filled joints/shears also occur. Pyritisation is commonly associated with many of the deposits and an intensely pyritised zone over 2 km in length has been mapped closely associated with the Victor mine along the inferred Mt Usher fault system.

GEOCHEMISTRY - Wall samples from Mt Usher and the New Golden Cave returned no significant gold values except in some of the thin reefs.

2) North Mine Corridor

GEOCHEMISTRY - Rock chip sampling was carried out but the results are not yet available.

3) Champion area - 3 km ENE of the Mount Morgan open pit and includes the Champion, South Champion, Golden Cross, Welcome, Peuts and Retrieve mines which occur within a zone approximately 1300x700 m. Numerous other small pits and workings also occur within the zone.

GEOCHEMISTRY - Rock chip samples were collected from the country rock and results are awaited.

4) Belgamba

GEOPHYSICS - The geophysical data on Belgamba was re-appraised. Further ground magnetics and EM are recommended over an area of coincident IP and magnetic anomalism.

5) Clanricarde area - 3.3 km NW of the Mount Morgan pit. The area includes the Clanricarde, Midas and Crows Nest Mine. Production to July 1949, was 2000 oz Au (grade approximately 1.4 oz/t), 5.5+t Cu (grade approximately 2.1%), and 146+ oz Ag (grade approximately 0.6 oz/t).

6) Grillo Hill area - including the area to the NW, towards the Eureka mine.

GEOLOGY - Reconnaissance mapping was carried out in this area to locate possible skarn type, low grade gold, near the edge of the Station Creek Granodiorite.

GEOCHEMISTRY - Rock chip samples returned high values from weakly pyritic limestone dump material from the adit at Eureka, and from the adit entrance wall.

7) Fab area

GEOLOGY - Seven samples from drill hole DDH 69-6 were sent for a petrological/mineralogical study and comparison with Ajax mineralisation. Results are awaited.

8) Fern Hills area

GEOCHEMISTRY - Rock chip samples were collected from pyritic rocks at the E edge of the grid. Results indicate very low gold values. One line of soil geochemistry was re-assayed, and results indicate no Au values greater than 0.05 ppm.

9) Mount Dick area

GEOCHEMISTRY - Gossanous-ferruginous rocks were re-sampled and analysed for gold. Results indicate a maximum value of 0.60 ppm Au in the N gossan. Samples from two previous lines of soil geochemistry were sieved and analysed for gold. Results indicate no values greater than 0.05 ppm Au.

10) King Solomon - These workings are situated 37 km SE of the Mount Morgan pit, and the workings consist of several shafts, pits and an adit.

GEOLOGY - The country rocks are andesitic tuffs. No large zones of alteration or quartz veining were noted. A large (100 m diameter) diorite intrusive occurs to the E of the prospect.

11) Queen of Sheba - These workings occur approximately 1.8 km S of the King Solomon workings.

GEOCHEMISTRY - The costeans were sampled and revealed low gold values except for some quartz veins in the southern costean.

12) Diggers Dive - These workings include several pits, adits, and shafts near the top of a small peak above Kangaroo Creek, 3.25 km SE of the Queen of Sheba workings.

GEOLOGY - Reconnaissance mapping confirmed a tuff (andesitic), sedimentary sequence, overlain by Pond Formation conglomerate. No significant areas of alteration were seen.

13) Upper Manton

GEOCHEMISTRY - Previous soil sampling was re-assayed for gold. Maximum value recorded was 0.05 ppm Au.

14) Upper Don

GEOCHEMISTRY - Several rock samples were collected and assayed, and one line of soil samples were re-assayed. The results indicate a maximum value of 0.05 ppm Au.

Exploration was carried out on four areas within ATP 654M.

Rookwood Homestead -

Several small prospecting pits had been dug on copper stained gossan formed on spilitic and andesitic lavas east of Rookwood Homestead. A number of costeans were cut to provide better exposure. It was evident from the costean exposures that sulphide mineralisation was completely leached and that it was restricted to light coloured rhyolitic rocks. In most cases copper and zinc values were less than 1% but because of the presence of lenticular massive leached sulphide zones there was some chance that if the rhyolites thickened down dip substantial sulphide masses might exist. An IP survey was conducted to test this theory, but in general responses were poor over the rhyolite. An indeterminate source produced strong IP anomalies along the approximate contact between Rookwood Volcanics and Boomer Formation to the north of the area.

Ohio -

Ridge and spur sampling was conducted to test an area of Rookwood Volcanics in which a number of stream sediment samples gave higher than background values. Results indicate that the high drainage values are merely expressions of above background rock values throughout the area as opposed to definite mineralisation.

Balcomba Creek headwaters -

High zinc values occurred in a number of creeks in this area both on the original and follow-up surveys. A close interval stream sediment sampling programme was then carried out over the whole area. Subsequent ridge and spur soil sampling over the two highest drainage systems led to soil sampling on a 100' x 20' grid. The commonest rock type in the area is micaceous schist of the Rannes beds. Anomalous values were found to be due to very narrow (0.5 - 3.0 inch) ferruginous veins, mostly conformable with the schistosity, which individually assayed up to 2000 ppm Zn.

Four Mile Creek -

Ridge and spur soil sampling was undertaken at two localities near the headwaters of Four Mile Creek some 5 miles NE of Balcomba Homestead. The drainage systems in this area had slightly anomalous values for copper and to a lesser extent zinc.

Soil sample assays gave copper values up to 410 ppm. Detailed mapping attributed the cause of the anomaly to malachite as vugh fillings and staining of tuff and agglomerate or to malachite associated with irregular quartz veining.

Report for quarter ended 31/3/1971

Following the defining of IP anomalies over the Rookwood Volcanics/Boomer Formation contact in December 1970, field work was initiated to find the reasons for these anomalies.

The soil grid was extended to take in all previously unsampled IP lines. Soil samples were collected at 50' intervals.

Detailed geological mapping of the Boomer Formation/Rookwood Volcanics contact.

The geochemical results did not show anomalous results over the IP anomalies and the refined mapping showed that in all cases black or grey shales (boomer Formation) occurred in the anomalous IP areas.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -No further work was recommended and the ATP was relinquished.

SUMMARY:

GEOLOGY -

LOCAL -Silurian-Devonian trachyandesite and andesite flows and flow-breccias are the most common rock types in the ATP area and crop out predominantly west of Mt Cassidy. Siltstone, sandstone and greywacke (possibly tuffaceous) outcrop mainly on the eastern side of the ATP, commonly associated with narrow limestone lenses, volcanic flows and breccias.

Lower Carboniferous sediments unconformably overlie the Siluro-Devonian sediments on the east and west sides of the ATP where they crop out as part of the eastern and western limbs of the Craigilee Anticline. The sediments consist predominantly of banded light to dark grey siltstone, oolitic limestone and sandstone. Black, well bedded tuffaceous siltstone is well exposed in small creeks just north of the Rosewood road near Ten Mile Creek headwaters.

Disconformably overlying the Lower Carboniferous sediments are Upper Carboniferous Neerkol Formation sediments consisting of siltstone, limestone, sandstone and pebble conglomerate.

Deeply weathered outcrops of Permian intrusives are found within the ATP area.

Small dolerite and andesitic dykes cross-cut the Siluro-Devonian sediments and volcanics. These dykes trend east-west and are generally narrow.

Structural geology - Siluro-Devonian rocks in the ATP area represent the basement onto which sediments of the Yarrol Basin sequence were deposited. The Siluro-Devonian sequence occurs as an easterly-dipping wedge, with strikes varying between 340 and 70o and dips between 30 and 70o east. The granitic intrusion near the Fitzroy River has caused some warping and displacement of beds.

Minor local folding occurs in some of the less competent sediments.

The ATP area is cut by north-south and east-west trending faults. The main fault in the area is a north- south trending fault through Jenny,s Gully.

A major east-west zone of weakness exists in the immediate area of the granite intrusive. The Fitzroy River appears to have been diverted along this zone of weakness, and it has also been the site of intrusion of granite and east-west trending dykes.

MINERALISATION/ALTERATION -The Siluro-Devonian rocks in the area are generally extensively altered. Alteration is predominantly silicification, accompanied by epidote, chlorite and calcite mineralisation. Albitisation of silicified volcanics is also noticeable.

Quartz veins are common, and gold has been reported associated with these in the Mt Cassidy area.

Weak copper mineralisation was found associated with silicified volcanic flows at various localities within the ATP. This mineralisation is associated with pyrite but is extremely irregular in distribution and sparsely disseminated.

Pyrite mineralisation is widespread occurring in most volcanic rocks and some altered sedimentary rocks.

East of Ten Mile Creek in the northeast of the ATP, malachite is associated with a small skarn-type outcrop approximately 70 m x 3 m.

REGIONAL EXPLORATION

GEOCHEMISTRY

stream sediment sampling - 356 samples were collected at an average density of nine per square mile. The minus 80 mesh fraction was analysed for Cu, Pb, and Zn.

Very anomalous copper values were obtained from stream sediment samples in the drainage basin east of Mt Cassidy. A reconnaissance soil grid 1.6 km long x 0.8 km was constructed over this area.

Other copper anomalies were located SSW of Mt Cassidy in the area just north of the granitic intrusive. These were examined in the field but appear to be associated with small, erratic sulphide patches derived form the granite.

Spot anomalies were located at various other points in the ATP area but were of no significance.

Lead and zinc anomalies are generally spot anomalies and are of no significance. Some anomalous lead and zinc is associated with the major copper anomaly east of Mt Cassidy.

After field examination, the few small base metal anomalies associated with streams underlain by Carboniferous sediments were considered to be of no further interest.

LOCALISED EXPLORATION/PROSPECTS

GEOCHEMISTRY -

soil sampling - Mt Cassidy Grid - Soil samples were taken from the "B-C" horizon and the -80 mesh fraction assayed for Cu, Pb and Zn. Samples were collected at 100 feet intervals on a line spacing of 400 feet.

Statistical analysis of the results indicated the possibility of there being two different populations. To clarify the situation, rock chip samples were taken at 100 feet intervals over 800 feet spaced lines over the soil grid. Detailed geological mapping and petrographic analyses accompanied the rock chip sampling.

Results of rock chip assay compilation indicated clearly that the original soil anomalies were a reflection of the underlying rock types.

Ten Mile Grid - A small area of gossanous material 140 m x 3 m located in the northeastern corner of the ATP gave grab sample assay values of up to 2.4% Cu.

A soil grid constructed over the area gave high Cu values over a small area. Zinc values were quite low with anomalous areas confined to the major anomalous copper zone. Lead values were insignificant.

Follow up mapping and petrographic analysis indicated the gossanous material was associated with a small skarn-type area carrying minor amounts of malachite and azurite. The area was considered to be of no further interest.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -Reconnaissance geological mapping and stream sediment geochemistry outlined two areas of potential interest. Follow-up detailed geological mapping and rock chip geochemistry showed the anomalous areas to be associated with high background base-metal values.

Further exploration was not justified and the ATP was relinquished on 15/10/1972.

SUMMARY:

This area was previously held by BHP under ATP 294M.

GEOLOGY -

REGIONAL -Because the regional geology has been outlined in detail in BHP's reports on ATP 294M, it is not discussed in detail in this report on ATP 1224M.

LOCAL -The Great Northern copper mine lies within the Ridgelands Granodiorite. The Golden Bar and unnamed diggings (designated "B" on the report map) lie within a sequence of Silurian-Devonian basic volcanics and sediments. A number of roof pendants exist within the granodiorite.

Hydrothermal alteration of the Silurian-Devonian rocks occurred when they were intruded by the Ridgelands Granodiorite. The intensity of the hydrothermal alteration is largely related to proximity to the contact. The presence of broad, altered roof pendants, and the distribution of the more intensely altered zones of alteration (as mapped by BHP) suggest that the granodiorite has a much wider lateral extent below the surface.

Mapping by BHP showed good correlation between the intensity of hydrothermal alteration and mineralisation. A further control on mineralisation in this area is the presence of east-west trending shearing accompanied by quartz veining. Barite is commonly associated with this quartz veining, as a gangue mineral.

LOCALISED EXPLORATION/PROSPECTS

Great Northern Mine

Historic small scale mining operations have been conducted in this area in the search for copper mineralisation. The host rock is an altered mid-grey porphyritic intermediate igneous rock containing quartz and altered feldspar phenocrysts. Disseminated pyrite occurs in association with quartz veining striking 250o and dipping steeply to the south. The quartz veining is accompanied by barite and "knots" of chlorite.

Despite an abundance of copper carbonate minerals in the mullock heaps, no primary copper mineralisation was observed suggesting that the original workings were confined mainly to the oxidised zone.

Because of the obvious indications of copper mineralisation, this locality was chosen as the site for a drillhole designed to evaluate the potential of the previously mapped zone of intense alteration. The hole was drilled to 35m passing through mainly "altered siliceous igneous rock" (probably the Ridgelands Granodiorite). The best copper assay was 10ppm from a 15cm interval at approximately 10m below ground level. All gold assays were below 0.2ppm Au. Lead values were all below 10ppm. Zinc assays ranged from 10-20ppm.

Locality B

These unnamed workings, located approximately 1km east of the Great Northern mine, comprise shallow trenches sunk on quartz veins with associated pale- and dark-green quartz-epidote rocks. The veins strike 245o and possess steep dips. In places, very fine pyrite is disseminated through this vein material. No evidence of either primary or secondary copper mineralisation was noted at this locality.

The host rock is a coarsely porphyritic, altered andesite, associated with sheared and altered medium grained pink adamellite.

Golden Bar

A quartz vein, varying from 15cm to 30cm in thickness has been worked for gold at this locality. The vein strikes 255o and dips 80o to the north. The hanging wall comprises a dark-green, chloritic, altered basic igneous rock, possibly having an original porphyritic texture (andesite??). The footwall is sheared quartz-epidote rock containing minor chlorite. Barite is associated with the quartz vein.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -Mineralisation in the area is related to zones of intense hydrothermal alteration caused by the intrusion of the Ridgelands Granodiorite into Silurian-Devonian basic volcanic rocks. Further localisation of mineralisation is provided by east-west trending shear zones accompanied by quartz veining.

Drilling at the Great Northern zone of intense alteration yielded disappointing results. Further work on the Golden Bar and locality "B" was not justified and the area was relinquished.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -The ATP was acquired to search for refractory minerals, in particular chromite, within ultrabasic rocks of the Marlborough Block.

REGIONAL EXPLORATION

Geological mapping -Interpretation of aerial photographs identified zones of serpentinite in which to explore for chromite. Ground traverses located outcrops and areas of alluvial float of chromite.

GEOCHEMISTRY -- rock chip sampling -Two or three samples were collected from each sample site and submitted for analysis by AAS. Assay results were subjected to statistical analysis.

LOCALISED EXPLORATION/PROSPECTS

GEOPHYSICS - ground surveys -

An orientation geophysical survey including magnetics, resistivity and gravity was conducted over five small chromite deposits.

An experimental gravity geophysical survey was conducted over two surface deposits of chromite to determine if there is any significant excess mass associated with these deposits. No significant gravity anomalies were detected which is interpreted as indicating that there is no substantial tonnage of chromite at either deposit.

The magnetic contour plan of the Rosehill deposit indicates that the chromite occurs along the southern gradient of a magnetic low, very close to one end of the low.

The resistivity survey at the Balnagowan and Rosehill deposits revealed that the chromite deposits occur at the centre of resistivity highs. At Rosehill a small central low, very closely associated with the chromite ore, can be observed within the resistivity high.

GEOLOGY -Chromite deposits were bulldozed to determine lateral and vertical extent. In many cases bulldozing obliterated all traces of chromite, which in these case was thought to represent residual occurrences.

During the final six months of tenure three prospect areas were evaluated. In decreasing order of importance these are Merimal (including "The tube", "Dingo lode" and "13B").

Merimal

Three chromite outcrops occur in the Merimal area and are identified as "The tube", 13B, and "Dingo lode". A drilling grid was surveyed over the area.

Geological mapping was performed at 1:100 scale. Several rock samples were collected for petrological and XRD analysis. Serpentinite is the major rock type in the area and generally strikes north-south and dips to the east. A dyke of microgabbro 5 to 10m in width strikes 345o and dips 49o to the east.

The outcrop at "The tube" has a strike parallel to the host serpentinite. The chromite veins were up to 1m wide and cropped out discontinuously over a length of about 60m. The "Dingo lode" occurs roughly along strike about 100m south of "The tube". This occurrence was about 50cm wide and 4m long. The chromite outcrop "13B" consists of a series of small pods that have no apparent relationship to the host serpentinite.

Blues lodes

The geology of the Blues lode is similar to the Merimal area.

Roys lode

At this occurrence, the host serpentinite strikes east-west. Chromite occurs as boulders up to 1m diameter. Although a small drilling grid was surveyed at this location, it was not considered worthy of further investigation.

DRILLING

90mm diameter open holes were drilled using a crawlair rig. Access was a major problem. Of the forty holes that were drilled deeper than 3m none encountered any chromite. About fifteen large diameter holes were drilled at "The tube" to determine whether the chromite veins persist at depth. No chromite was found at depths greater than 2m.

All traces of the "Dingo lode" were removed during development of the access road. Subsequent drilling in this area failed to reveal further extensions to the mineralisation.

At the "13B" occurrence, the terrain was too treacherous to use the crawlair rig. About 25 holes were put down to a depth of 3m using a hand-held drill. Eleven holes encountered chromite, three of them encountered only chromite giving an ore thickness of 3m. The estimated reserve at this locality is at least 300t.

At "Blues lode" a few test holes were unsuccessful and the area was subsequently abandoned.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -Bulldozing of the chromite outcrops generally removed all traces of ore indicating that the chromite was of very limited extent. Open hole drilling had very limited success in finding sub-surface chromite. A reserve of about 300t was outlined at the "13B" occurrence. Additional reserves may be present in the form of alluvial chromite at the base of the mountain hosting the chromite pods. The "Blues lodes" were considered to be too disturbed to contain any substantial massive chromite ore. Any further exploration in the area should be concentrated around the "Merimal" area.

SUMMARY:

REASON FOR ACQUISITION OF TITLE - Investigation of area around Mount Chalmers for Mount Chalmers (?Kuroko) style deposit.

GEOLOGY -

REGIONAL -

Photo-interpretation of the area was attempted but the area was not conducive to this method of study due to the homogeneity of rock textures and culture.

Regional mapping at 1:10 000 scale was completed over an area west of Mount Chalmers covering 70 sq km. Preliminary findings of the programme were:-

- Between Mt. Chalmers and the Berserker Range the sequence can be divided into three major volcanic series: rhyolite-shale series andesite-dolerite series dacite-feldspar porphyry series

- Each volcanic series (or sub belt) has a north-south trend and shows complex interfingering with the adjacent series.

- North toward Yeppoon road an additional massive rhyolite series leads to a more complex stratigraphy.

- Mineralisation at Mt Chalmers, Wood Shaft, and Botos occurs at the same stratigraphic level in the middle of the rhyolite-shale series.

- A second horizon occurs at the top of the rhyolite-shale series below the andesites. This includes Hunter 1 and the gold-quartz mineralisation around the North Star gold mine (Hunter 5) and south towards Sleipner (Hunter 6).

LOCAL -

The area mapped by Geopeko can be divided into 3 areas, the first between Cawarral and the Emu Park road, the second area is south of Emu Park road, and the third is north of Yeppoon road. A description is provided for the major rock units in these areas and these units are listed by area and then oldest to youngest:-

CAWARRAL TO EMU PARK ROAD

- Mount Chalmers Rhyolite - Ellrott Rhyolite - Sleipner Andesite Tuff - Woods Andesite - Dacitic Feldspar Porphyries and Tuffs - Intrusive Dolerite Dykes and Sills - Intrusive Quartz-Feldspar Porphyries

SOUTH OF EMU PARK ROAD

- Tungamull Andesite Lavas - The Hunter 11 Horizon - Tungamull Dacite Tuffs - Intrusive Rocks

NORTH OF YEPPOON ROAD

- Feldspar Porphyries - Tuffs and Fragmentals - Rhyolites - Sediments - Intrusive Rocks

A brief description of each of these units is provided in the summaries for CRs 6720, 6957, 7696, and 7876.

Structure

Detailed structural analysis of the area was limited by the scarcity of bedding in outcrop due to the predominance of massive volcanics in the area. Regionally, however, beds in the area are observed to dip to the west at 200 to 700 and the sequence is interpreted to be younging in this direction. Minor dip reversals are thought to be caused by local folding. Detailed mapping in the northern part of the area mapped enabled a reasonable interpretation of the local structure of the geology. Major faulting is absent and the rocks are gently folded about a north-west to north trending axes giving rise to shallow dips of 150 to 400 with steepening along the fold hinges, especially adjacent to dolerite contacts (e.g. Woods Shaft).

At the southern end of the Hunter 11 Horizon (CRs 6951 & 7696) a major fold structure is apparent on the air photos and has been confirmed by mapping on the ground. Inspection of the photo to the south (no. 54, Q2691) by the company indicated that this may be a large scale anticlinal fold effecting a stratigraphic thickness of 2 to 3 km of rock.

GEOCHEMISTRY

- stream sediment sampling -

Data was collated from reports of previous work done in the area (reports held by the Mines Dept.) including reports by International Nickel of Australia Limited and Electrolytic Zinc Company of Australasia Limited. This data was being plotted onto a compilation map at the time the company report was written. Results plotted in time for the report were shown in a number of plates.

LOCALISED EXPLORATION\PROSPECTS

MOUNT CHALMERS

A brief description of the stratigraphy of the Mount Chalmers Mine is provided in company reports 6720 and 6951 after Large (1978). The footwall rocks are described as massive, altered, siliceous pyroclastics (probably originally of rhyolitic to dacitic composition) which have undergone various types of alteration. The hanging wall sequence is unaltered but mildly chloritic and dominated by feldspar crystal tuffs, lithic tuffs, and cherty siltstones. The hanging wall rocks are intruded by transgressive dolerite sills and quartz feldspar porphyry sills.

HUNTER 1

GEOLOGY -

This prospect was discovered during reconnaissance of a grid extended from the Mount Chalmers mine grid. Outcrop is confined to the southern and western sides of the grid and a discussion of the alteration zone is given in the summary for company report 6951. A detailed discussion of the geology and geological maps of the area are included in company report 6951.

GEOCHEMISTRY -

Rock chip analyses from isolated outcrops along the Hunter 1 zone are given in the company report. The gold and silver values on the barite zone are significantly anomalous despite the fact that copper, lead and zinc values are generally low. Silver varies from 3 to 80 g/t (average 26 g/t) while gold varies 0.03 to 0.8 g/t (average 0.31 g/t). Background values for these metals within the Berserker beds are about 1- 2 g/t Ag and 0.02 g/t Au.

HUNTER 2

The prospect was discovered by Geopeko in an I.P. survey of the Hunter 1 grid (see CR 6951).

GEOCHEMISTRY -

Rock chip analyses of selected samples of the limonitic and weakly gossanous siltstone from Hunter 2 were provided in the report and included the following ranges:-

Cu - 10 to 110 ppm Pb - 10 to 75 ppm Zn - 60 to 940 ppm Ag - 1 to 2 ppm Au - 3 to 10 ppb Ba - 220 to 1500 ppm

Geopeko considered the zinc values to be moderately anomalous. A few traverses of hand auger soil samples were taken over the outcrops and intervening alluvium and zinc values from these samples showed an increase from 40 to 155 ppm south of the main outcrop area. Anomalous zinc rock chip values were not repeated in the soil sampling.

GEOPHYSICS -

The grid area described above was covered by magnetics and gradient array I.P. with resistivity. Two anomalies were found in the magnetics. The first anomaly strikes north-west across the grid and peaks at approximately 900nT. It appears to cut across north of the barite zone at Hunter 1. A hole augered on the anomaly intersected weathered magnetic andesite believed by Geopeko to be the cause of the anomaly. The second anomaly was narrow (30 - 50m wide) and trended north-south immediately south into the dolerite. This anomaly was reported to be caused by a narrow basic dyke.

HUNTER 11

GEOLOGY - A detailed description of the geology in the Hunter 11 grid was provided in company reports 6951 & 7691. The units identified by further mapping during the reporting period are listed in stratigraphic order (from youngest? to oldest?) below:

- Ellrott Rhyolite - Andesitic Lava, Microdolerite - Rhyolitic Tuff, Pyritic Siltstones, Greywackes, Minor Fragmental Tuff - Dacitic Tuff - Andesitic Tuff

The sequence dips moderately westward and flexures in the geophysical data (see CR 6951 & 7696) suggest cross-faulting occurs in the area.

GEOCHEMISTRY - Not all of the Hunter 11 grid was soil sampled because of extensive areas of flat alluvial cover. In areas of outcrop and rock float, hand-auger samples were taken at 25m intervals on crosslines 200m apart to a depth of 30 to 50cm. B-horizon copper values were low throughout the gridded area, the highest being 420 ppm Cu on calcareous ash tuff which previously gave rock chip values of 270 ppm Cu, 460 ppm Pb, and 310 ppm Zn. A broad roughly strike conformable zone above 50 ppm Cu and up to 200 ppm Cu covers an area of andesitic lavas, microdolerite intrusives, rhyolitic tuffs, and calcareous, pyritic siltstones and shales in the southern part of the grid. Values elsewhere are spotty, with only low values over the pyrophyllite zone.

Generally, the company found that the Hunter 11 sequence was a low zinc environment whereas copper and lead (and also barium) reach high levels in rock-chip and soil samples.

No silver anomalies were found in the soil samples but rock chip samples gave results of up to 6ppm from the central part of the Hunter 11 grid.

A prominent nickel soil geochemical anomaly with values above 25 and up to 320 ppm Ni extends south from the feldspar porphyry intrusive unit outcropping on line 10400N from 10200E to 10500E. Nickel was also uniformly high over andesite lava ( over 25 ppm, up to 110 ppm).

HUNTER 18

GEOLOGY - Reconnaissance mapping of south of the Hunter 11 grid (see CR7696) led to the discovery of jasperous boulders and weakly gossanous altered rocks in a restricted stream catchment. The Hunter 11 grid was extended and this new area defined as Hunter 18. A gossanous alteration zone with associated anomalous geochemistry was delineated. The sequence is an extension of the Hunter 11 sequence and dips at about 600 west (see summary for CR 7876).

GEOCHEMISTRY - B-horizon soil samples were taken with a hand auger over the whole of the grid. Results are summarised as follows:

- Copper values showed a discrete anomaly peaking at 0.18% coincident with the alteration zone. - Lead values show a discrete anomaly in the same position as the copper anomaly peaking at 0.4% Pb. - Zinc values show a coincident anomaly with Cu and Pb but zinc is more broadly dispersed. The peak value is 1500ppm but the anomaly is over 800ppm for 400m strike length. - Silver values also have a coincident anomaly peaking at 11ppm Ag. - Low level gold values reach a one-point peak on one line but generally are scattered and low and thought to be due to analytical variation.

BROADMOUNT BLOCK

GEOLOGY - The southernmost section of the ATP, the Broadmount Block ( see CR 8164), consist of a prominent central core of dacitic lithic tuffs which are fragmental in the western side. This central domal core is overlain by the favourable rhyolitic tuff horizon which is dipping away from the core on the north and west. Minor pyritic alteration zones occur within the rhyolitic tuff unit on the north and on the south at Thompsons Point. On the west the well bedded shale-siltstone sequence lies above the rhyolitic tuff, probably unconformably but without the andesite unit intervening.

HUNTER 19

GEOLOGY - A southern extension of the Hunter 18 mineralised zone was gridded and mapped (see CR 8786). This stratiform pyritised horizon was traced south from the Rockhampton Emu Park road along the Hunter 11 grid. The H18-H19 areas were found to be the only geochemically anomalous zones of any significance within the horizon.

The stratigraphy of the Hunter 19 grid, described in more detail in the report, dips moderately to steeply west. There is a suggestion, however, of dip reversals to steeply east in the southern end of the area mapped. The dominant feature of the geology is the broad pyritised chloritic rhyolitic tuff occurring in the centre of the grid which was believed to be block faulted. Overlying the alteration zone is a sequence of non- pyritic rhyolitic tuff with minor interbeds of feldspathic crystal tuff and andesitic tuff. Higher in the sequence, towards the west, is a black shale unit and a second area of patchy pyritic alteration. A thick andesitic to dacitic tuffaceous sequence is reported to unconformably overly the mixed rhyolitic to dacitic sequence which contains the mineralised zone.

The stratigraphy underlying the pyritic alteration zone on the western side of the grid is complex. It consists of an interbedded sequence of sandy rhyolitic tuff, crystal tuff, and minor black shale and large areas of intrusive andesite. The dip of the sequence is uncertain.

The mineralised zone on H18 is reported to be a complex faulted anticline and it was believed that this complexity extended southwards to the H19 grid.

GEOCHEMISTRY - Hand auger b-horizon soil sampling was completed on a 25m line spacing. The results of analyses of these samples are summarised as follows:-

COPPER - Andesitic rocks within the grid show a higher copper geochemical background than the rhyolite-dacite suite. A discrete anomaly occurs in the grid reaching values of 0.17% Cu. The anomaly is terminated to the south by a fault.

LEAD - The distribution of the values shows a much more discrete anomaly coincident with the copper anomaly but extending across the fault line to the south in two discrete trends.

ZINC - shows a broader distribution around the copper-lead anomaly and trends further south and southeast. Other localised zones of weak anomaly occur sporadically but appear insignificant.

SILVER - Two values of 3ppm coincide with the centre of the copper-lead-zinc anomaly. Two other values of 3ppm occur on the eastern end of line 5700N in andesite.

MANGANESE - Small zones of magnesite above 1000ppm occur coincident with the copper-lead-zinc anomaly, and also on the southeast of the area sampled at the time the report was written.

DRILLING -

Four percussion drill holes were put down on the geochemical anomaly. One hole was put down as a water supply.

HUNTER 15

GEOLOGY - Anomalous gold values (to 1.35 g/t Au) found during the previous period (see CR8786) on the north end of Hunter 11 grid, south of the Emu Park - Keppel Sands road junction, were investigated with a detailed grid, rock and soil sampling, and an I.P. survey (see summary for CR 10593).

The mineralised zone at Curlew Hill is part of the rhyolitic volcanoclastic sequence striking north-south through the Hunter 11 area. GEOCHEMISTRY - B-horizon soil samples were taken at depths of 0.3 - 0.5m. Results for Cu, Pb, Zn, Ag, Ni, and Au are detailed in Figs 5 - 10 in the company report 10593.

Copper values are very low, the highest being 65ppm on the edge of the flat. Lead results era also disappointing, the highest being 30ppm on the siltstone horizon. Zinc values are poor, the highest results being 60ppm. Silver values are spotty with the gossan and the siltstone horizon being less than 1ppm. Nickel displays the boundary of the Tungamull Fault, with values over 100ppm lying to the east of the fault; and values up to 200ppm occur on the alluvial cover to the west of Curlew Hill.

Gold in soils forms three distinct anomalies (threshold taken as 100ppb). The main anomaly is centred over the gossan zone and reaches a peak of 270ppb to the west.

Rock float geochemistry was carried out Cu, Pb, Zn, Ag, Ni, and Au and results are brief results are available in company report summary for CR7876.

DRILLING -

A single percussion drill hole was dropped to test a discrete anomaly on the H15 grid. The hole was drilled to 150m and intersected pyritic carbon-rich shale from 27m to 63m which was interpreted to be the source of the I.P. anomaly.

MOUNT SLEIPNER

A ridge and spur soil sampling programme was carried out over the eastern portion of the Mt Sleipner area and 134 samples were analysed for Au, Cu, Pb, and Zn. Peak values of 140ppm Au, 200ppm Cu, 190ppm Pb, and 310ppm Zn were recorded but these were isolated values and no broad anomalies were defined (see CR 11588 and summary).

NORTH STAR

GEOLOGY -

A background to the geology of the area and a description of favourable horizons can be found in company reports 6720, 6951, 7696, 7876, and 7877. Further mapping confirmed that the Mount Chalmers mineralised horizon continued southwards from the northern edge of ATP 1896M along the western flank of the regional syncline (see CR10594 $ 11588). Fact geology sheets are included in report 10594.

GEOCHEMISTRY -

A ridge and spur soil sampling programme was conducted over the area during the reporting period. Detailed results are given in tables in the report and are summarised as follows:-

COPPER - values were generally low except for an a area near old mine workings where one high spot reaches 2000ppm.

LEAD - values correspond with copper value highs but Pb values are also anomalous in the north and centre of the area sampled reaching peaks of 1000 and 1400ppm.

ZINC - values were high in the area of the old workings, central and southern parts of the area sampled reaching a peak of 1900ppm.

Field examination showed that all anomalous areas relate to weakly altered rocks of the favourable Mt. Chalmers mineralised horizon and was considered of prime interest for further exploration for a Mt. Chalmers type copper-gold orebody.

Anomalous areas for Cu, Pb, and Zn were investigated to determine the cause of the anomalies. The areas were found to be associated with quartz veining with gossanous (after sulphide?) material. The base metal sulphides are thought to be due to base metal sulphides associated with the quartz veining. No gold values were detected in the soil geochemistry and no gold workings occur in the area.

DRILLING -

HIDDEN KING

GEOLOGY -

Gold Fields Exploration mapped the mine workings of the Hidden King mine in 1983 (see company report 12276 and summary).

Stoping has occurred in thin shallow-dipping siliceous ash tuff and graphitic shale horizon that occur above a quartz feldspar porphyry and an andesite ?sill. The sill/ore sequence appears to occupy an axial position in a gently north plunging syncline. The sequence occurs within a broader sequence of rhyolitic, lithic, crystal tuffs. No production figures were available but sampling of material in wells of the stopes revealed maximum gold values of 0.29g/t indicating a very patchy distribution which has been completely removed.

GEOCHEMISTRY -

NEW ZEALAND GULLY

Soil sampling was carried out at New Zealand Gully and North Star grid in 1983 (see CR 12276 and summary).

A grid measuring 450m x 300m was surveyed over the area of anomalous gold values detected in reconnaissance sampling. Line spacing was 50m and pegs were spaced 25m along lines. Soil samples (-80#) were taken at each peg and assayed for Au, Cu, Pb, and Zn. Rocks on the grid consist essentially of massive sericitic tuffs, probably stratigraphically equivalent to the sequence at Hidden King. Strongly silicified to vitric, pyritic tuffs ?overlie the sequence to the south.

Base metal values were generally low with four spot highs for lead (max 840ppm) and five spot highs for zinc (max 1100ppm). A trend of higher than background Pb and Zn values from NW to SE is indicated, which coincides with a trend in gold values (max Au values are 2.29 and 1.12 g/t). No pattern of distribution of old workings or quartz veining was recognised and the bulk tonnage potential of the grid was thus downgraded.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE - The results of mapping and geochemical sampling of some of the areas which contain old gold workings did not reveal any indication of bulk mineable gold deposits and, accordingly, the Authority was terminated (see CR 12276).

SUMMARY:

REASON FOR ACQUISITION OF TITLE - Investigation of area around Mount Chalmers for Mount Chalmers (?Kuroko) style deposit.

GEOLOGICAL MAPPING -

Photo-interpretation of the area was attempted but the area was not conducive to this method of study due to the homogeneity of rock textures and culture. Regional mapping at 1:10 000 scale was completed over an area west of Mount Chalmers covering 70 sq km. Preliminary findings of the programme are:-

- Between Mt. Chalmers and the Berserker Range the sequence can be divided into three major volcanic series: rhyolite-shale series andesite-dolerite series dacite-feldspar porphyry series

- Each volcanic series (or sub belt) has a north-south trend and shows complex interfingering with the adjacent series. - North toward Yeppoon road an additional massive rhyolite series leads to a more complex stratigraphy. - Mineralisation at Mt Chalmers, Wood Shaft, and Botos occurs at the same stratigraphic level in the middle of the rhyolite-shale series. - A second horizon occurs at the top of the rhyolite-shale series below the andesites. This includes Hunter 1 and the gold-quartz mineralisation around the North Star gold mine (Hunter 5) and south towards Sleipner (Hunter 6).

SUMMARY:

GEOLOGY -

REGIONAL - The report provides a description of the Berserker beds and divides them into three "series" based on composition. The series identified are listed as follows:-

- rhyolite series - andesite series - dacite series

The author of the report, Alex Taube, notes that detailed structural analysis of the area is limited by the scarcity of bedding in outcrop due to the predominance of massive volcanics in the area. Regionally, however, beds in the area are observed to dip to the west at 200 to 700 and the sequence is interpreted to be younging in this direction. Minor dip reversals are thought to be caused by local folding.

LOCAL - A brief description of the stratigraphy of the Mount Chalmers Mine is provided in the report after Large (1978). The footwall rocks are described as massive, altered, siliceous pyroclastics (probably originally of rhyolitic to dacitic composition) which have undergone various types of alteration. The hanging wall sequence is unaltered but mildly chloritic and dominated by feldspar crystal tuffs, lithic tuffs, and cherty siltstones. The hanging wall rocks are intruded by transgressive dolerite sills and quartz feldspar porphyry sills.

The area mapped by Geopeko is then divided into an area between Cawarral and the Emu Park road and an area south of Emu Park road. A description is provided for the major rock units in these areas and these units are listed by area and then oldest to youngest:-

CAWARRAL TO EMU PARK ROAD

SOUTH OF EMU PARK ROAD

- Tungamull Andesite Lavas - The Hunter 11 Horizon - Tungamull Dacite Tuffs - Intrusive Rocks

STRUCTURE

Detailed mapping in the northern part of the mapped area enabled a reasonable interpretation of the local structure of the geology. Major faulting is absent and the rocks are gently folded about a north-west to north trending axes giving rise to shallow dips of 150 to 400 with steepening along the fold hinges, especially adjacent to dolerite contacts (e.g. Woods Shaft).

At the southern end of the Hunter 11 Horizon a major fold structure is apparent on the air photos and has been confirmed by mapping on the ground. Inspection of the photo to the south (no. 54, Q2691) by the company indicated that this may be a large scale anticlinal fold effecting a stratigraphic thickness of 2 to 3 km of rock.

MINERALISATION/ALTERATION - chloritisation, sericitisation

REGIONAL EXPLORATION

GEOCHEMISTRY

- stream sediment sampling - data from all pre-existing surveys was obtained from the Department of Minerals and Energy and collated and plotted on a series of 1:25 000 sheets. Sample locations were shown on maps in the report and the results for copper, zinc, and lead were tabulated.

- soil sampling -

Ridge and spur soil samples from previous work done in the area were compiled and the results of analyses of these samples for copper, zinc, and lead were tabulated.

LOCALISED EXPLORATION/PROSPECTS

GEOLOGY -

Detailed exploration work was carried out in the area north of ATP 1565M extending northwards from the Mount Chalmers Mine, known as Mitchell's Flat. A reconnaissance grid was surveyed from the Mount Chalmers baseline using a line spacing of 200m and covering an area of 1600 x 2600m. Fill in lines were used over the Hunter 1 prospect discovered during the survey. Outcrop is confined to the southern and western sides of the grid and a discussion of the rocks in the area is included in the report. The Hunter 1 alteration zone is in a complex zone of rhyolitic and sedimentary rocks which are cut off by a large body of fine-grained dolerite similar to those at Mount Chalmers. The alteration zone consists of a weakly pyritic barite-quartz zone about 400m long by 50-100m wide, reaching its widest point at the north end.

In the southern part of the grid are a number of low outcrops of weakly pyritic tuffs and siltstones with some isolated, brecciated, gossanous patches. The central part of this area coincides with a major I.P. anomaly and has been designated Hunter 2. The eastern part of this area is known as Hunter 3.

GEOCHEMISTRY - B-horizon auger samples and surface rock chip samples were collected in the outcrop areas of Hunter 1 and Hunter 2. The results are summarised by Taube as follows:-

HUNTER 1

Significant comments on commodities from Hunter 1 which were given in the report include:-

LEAD: shows a circular anomaly varying 100 to 1200ppm measuring about 200m long by 150m wide. Background is 10 - 20 ppm.

ZINC: an anomaly with value from 100 to 3800 ppm covers a similar area to the lead. Background varies 10 to 80 ppm.

COPPER: no anomaly defined. A zone of 50-110 ppm covers the northern end of the barite zone and transgresses into the andesite passing south.

BARIUM: a well defined anomaly varying from 1000 ppm to 3.9% covers the barite-quartz zone.

MANGANESE: an anomaly from 1600 ppm to 6400 ppm occurs along the western edge of the barite zone.

GOLD: only one traverse was analysed for gold. An anomaly with values from 50 to 250 ppb coincides with the barite-quartz outcrop. Background is 2 to 25 ppb.

NOTE: the highest values of zinc and lead sit over the siltstone-chert-jasper horizon to the west of the barite zone.

HUNTER 2 Rock chip analyses of selected samples of the limonitic and weakly gossanous siltstone from Hunter 2 were provided in the report and included the following ranges:-

Cu - 10 to 110 ppm Pb - 10 to 75 ppm Zn - 60 to 940 ppm Ag - 1 to 2 ppm Au - 3 to 10 ppb Ba - 220 to 1500 ppm Geopeko considered the zinc values to be moderately anomalous. A few traverses of hand auger soil samples were taken over the outcrops and intervening alluvium and zinc values from these samples showed an increase from 40 to 155 ppm south of the main outcrop area. Anomalous zinc rock chip values were not repeated in the soil sampling.

GEOPHYSICS -

Resistivity profiles for the grid are strongly attenuated due to the highly conductive alluvial cover and as a result the data were not very useful.

I.P. data collected over the grid indicates a constant background over the alluvium of 5mv/v, with background across the outcrop areas variable from 5 too 15mv/v. Geopeko identified two anomalous areas above this background:-

1) A distinct anomaly with values up to 25mv/v occurs in the south-central portion of the grid, adjacent to the pyritic shale that outcrops at Hunter 2. The main anomaly (over 25mv/v) is centred over the alluvium between the pyritic shale outcrops. Geopeko thought that the anomaly was caused either by polarised clays in the alluvium or a body of disseminated sulphides at depth. The results of an I.P./resistivity depth probe showed that the zone of greatest polarisation was below 35m in depth and, therefore, supported the interpretation that a sulphide body was causing the anomaly. Whether the body is disseminated, stringer-type, or massive is not discernible.

2) A weak anomaly of 15mv/v on a background of 10mv/v occurs over the baritic outcrops at Hunter 1 and extends south as a broad flat topped anomaly over the dolerite outcrops.

SUMMARY:

GEOLOGY -

REGIONAL -

The geological mapping programme referred to in company report 6951 continued during this reporting period. The area from Yeppoon road and northwards was mapped and included relatively thick homogeneous sequences of rhyolites, feldspar porphyries, and dacitic tuffs. These units were subdivided as follows:-

- Feldspar Porphyries - Tuffs and Fragmentals - Rhyolites - Sediments - Intrusive Rocks

A brief description of each of these units was provided in the report.

MINERALISATION/ALTERATION - sericitisation

LOCALISED EXPLORATION/PROSPECTS

GEOLOGY - A detailed description of the geology in the Hunter 11 grid (see CR 6951) was provided in the report. The units identified by further mapping during the reporting period are listed in stratigraphic order (from youngest? to oldest?) below:

- Ellrott Rhyolite - Andesitic Lava, Microdolerite - Rhyolitic Tuff, Pyritic Siltstones, Greywackes, Minor Fragmental Tuff - Dacitic Tuff - Andesitic Tuff

The sequence dips moderately westward and flexures in the geophysical data (see CR 6951) suggest cross-faulting occurs in the area.

Outcrop of pyritic Tuffs and siltstones which gave rock chip values of 205 ppm Cu, 440 ppm Pb, 260 ppm Zn, and 2400 ppm Ba, did not cause any high values in the soils.

Similarly, the Curlew Hill gold diggings did not reveal any high copper values in the soils.

B-horizon lead values gave better definition with steeper gradient anomalies over the favourable horizon at Hunter 11 than copper. The most prominent feature of the lead soil geochemistry is the group of high values (>20 ppm Pb) directly west of, and along strike from, Pyrophyllite Hill. A more detailed discussion of lead geochemical data in the grid and its correlation to I.P. contour plans is provided in the company report.

Generally, the company found that the Hunter 11 sequence was a low zinc environment whereas copper and lead (and also barium) reach high levels in rock-chip and soil samples.

No silver anomalies were found in the soil samples but rock chip samples gave results of up to 6ppm from the central part of the Hunter 11 grid.

GEOPHYSICS - Further refinement of the I.P. survey, referred to in CR6951, was completed during this reporting period. A weak anomaly extended over the length of the grid and appeared to delineate the pyritic siltstone unit which is the favourable horizon. A broader anomaly was related to a pyritic pyrophyllite rock. Dipole-dipole I.P./resistivity results from line 8800N showed an anomaly related to a steeply dipping, near surface sulphide source within the shale-siltstone unit. Further discussion on the interpretation of this survey was provided in the report.

LOCALISED EXPLORATION/PROSPECTS

HUNTER 15 GRID

GEOLOGY - Anomalous gold values (to 1.35 g/t Au) found during the previous period on the north end of Hunter 11 grid, south of the Emu Park - Keppel Sands road junction, were investigated with a detailed grid, rock and soil sampling, and an I.P. survey.

The mineralised zone at Curlew Hill is part of the rhyolitic volcanoclastic sequence striking north-south through the Hunter 11 area. The Hunter 11 sequence is thought to dip moderately westward and on Curlew Hill one dip measurement of 600 W was obtained from a foliated limonitic siltstone outcrop. The Curlew Hill volcanic-sedimentary horizon is stratigraphically lower than the Pyrophyllite Hill sericitic-limonitic tuff horizon, and extends northwards into the Striker 1 grid. The horizon may be a northern facies variation of the andesitic-dacitic lithic/fragmental tuffs.

The gossan zone consists of silicic and argillaceous, banded, massive, and disseminated gossan float within a banded chloritic and limonitic siltstone horizon. The banded gossan consists of interconnected limonite bands in a cream argillite. The massive gossan is black to deep red in colour, heavy, with a vuggy texture. The vughs are coated with brassy iron oxides and filled partly with a white clay mineral. Remnant quartz can be seen, and a fine banding is evident in some samples. Wiry and contorted foliae of free gold were observed in specimens held by Mr. Fred Ellrott and reported to have come from this prospect. The disseminated gossan is a strongly limonitic to fine grained equigranular silicic rock. Examples of massive gossan occurring as veins in the disseminated limonitic rock can also be seen.

The siltstone horizon containing the gossan zone strikes at 3400 and dips westward at 600 . The horizon has been delineated by float mapping over an area of 200m x 70m. Lithologically it consists of calcareous, manganiferous, and chloritic siltstone, andesitic ash tuff, black chert, and strongly limonitic argillaceous siltstone.

Stratigraphically below the siltstone horizon is a sequence of pyritic, silicic micro-crystal tuff, spherulitic, fine acid rock, and cherty tuff. Above the siltstone horizon lie pyritic (vein and disseminated) silicic ash tuff.

The eastern side of the pyritic horizon abuts the Tungamull Fault, which strikes NW. A transcurrent fault may exist south of the Curlew Hill zone with a horizontal sinistral movement of 200m. The effects of faulting and folding are poorly known because of absence of outcrop.

To the northwest, the mineralised zone disappears below alluvial covered flats to reappear as a moderately pyritic barren acid tuff horizon (Striker 1) extending 1km north west.

GEOCHEMISTRY - B-horizon soil samples were taken at depths of 0.3 - 0.5m. Results for Cu, Pb, Zn, Ag, Ni, and Au are detailed in Figs 5 - 10 in the company report.

Gold in soils forms three distinct anomalies (threshold taken as 100ppb). The main anomaly is centred over the gossan zone and reaches a peak of 270ppb to the west.

Rock float geochemistry was carried out Cu, Pb, Zn, Ag, Ni, and Au and results are detailed in the company report. These results are summarised below.

A copper anomaly was found reaching a value of 560ppm.

Lead values reached a peak of 210ppm and two distinct anomalies were found trending north-south.

Zinc results were very low with the highest being 155ppm.

Barium values in the float samples are relatively low, the highest being 1470ppm in rhyolitic crystal tuff.

The highest gold value was 1.1ppm within the gossan zone. Gold over 100ppb forms two distinct zones trending north-south.

Comparing Au, Cu, Pb, and Ba results over the Curlew Hill mineralised zone it was noted that the 100ppm Cu contour closely follows the 100ppb Au contour. The lead values lie towards the eastern side of the zone, following the siltstone horizon. Lead and copper are both open toward the north. The barium zones over 500ppm overlie the western gold anomaly and also flank the copper and gold zones to the north and south, along strike.

GEOPHYSICS - An I.P. anomaly was revealed over the H15 area during the reconnaissance survey of the Hunter 11 grid. Five lines of dipole-dipole I.P. were surveyed over the Hunter 15 grid to cover this anomaly.

A clear double peaked anomaly was revealed by the survey. The major peak on the eastern side reached a peak of 3.5% at approximately 10575E and a lesser peak was also noted. The larger easternmost peak may reflect a black slate bed at depth. The smaller westernmost peak was considered to be associated with the gossanous zone and was thought to represent a small sulphide accumulation at depth.

HUNTER 18 GRID

GEOLOGY - Reconnaissance mapping of south of the Hunter 11 grid, surveyed in the previous reporting period, led to the discovery of jasperous boulders and weakly gossanous altered rocks in a restricted stream catchment. The Hunter 11 grid was extended and this new area defined as Hunter 18. A gossanous alteration zone with associated anomalous geochemistry was delineated.

The sequence is an extension of the Hunter 11 sequence and dips at about 600 west. The oldest rocks gridded are in the northeast corner of the sheet and consist of feldspar-quartz porphyry lavas, (fqp) which are glassy and fresh on the surface, occurring as bold outcrops and rubbly hills. Overlying the fqp to the west is a sequence of rhyolitic tuffs (Rt). These are acid lithic tuffs, generally fine-grained, rarely fragmental and monotonous in character. There are minor sandy horizons with rare bedding in the sequence. Pyrite is common within the unit at about 2-3%. Minor pyritic alteration zones occur but appear insignificant. Minor intrusive dolerites occur within the sequence. South of the major E-W fault the dolerites increase in thickness and minor lenses of feldspar-quartz porphyry occur. Near the top of the Rt are lenses of black shale. These are apparently discontinuous and interfingering with the rhyolitic tuffs. They contain disseminated pyrite.

At the top of the Rt sequence is the major alteration zone (Alt. Rt) which appears to be part of the Rt. This zone consists of an intensely altered, variably pyritic and gossanous muscovite-sericite-chlorite zone. The zone is recessive except where silicified, and one siliceous part of the zone forms a high central hill on the prospect.

Minor cherts occur within the alteration zone. Jaspers, which occur as float in creek beds, probably derive from this zone.

Local small rich gossans occur within the alteration zone and appear to be stringer zones rather than massive gossan.

Overlying the alteration zone south of the main E-W fault is a continuation of the Rt sequence. These are, in turn, overlain by a major sequence of andesite and dolerite (dol). These are apparently extrusive, consisting of breccias and vesiculated andesites, with some lapilli tuff.

In the northwest corner of the sheet stratigraphically above the dolerite is a complex sequence of rocks which were mapped as part of the Hunter 11 grid. These consist of rhyolitic tuffs, andesites, black shales, and feldspar-quartz porphyry.

GEOCHEMISTRY - B-horizon soil samples were taken with a hand auger over the whole of the grid. Results are summarised as follows:

GEOLOGY -

LOCAL - see company report 6720

MINERALISATION/ALTERATION - Weakly mineralised alteration zones were defined in several areas within the Hunter 18 southern extension and occur within the rhyolitic tuff horizon. Further investigation in this southern extension is foreshadowed in the report. Mineralised zones elsewhere in the ATP are discussed in company reports 6720, 6951, 7696, and 7876.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION - see company reports 6720, 6951, 7696, and 7876.

GEOLOGICAL MAPPING - The company completed some reconnaissance mapping during the reporting period and results are summarised (from the report) below.

The southernmost section of the ATP, the Broadmount Block, consist of a prominent central core of dacitic lithic tuffs which are fragmental in the western side. This central domal core is overlain by the favourable rhyolitic tuff horizon which is dipping away from the core on the north and west. Minor pyritic alteration zones occur within the rhyolitic tuff unit on the north and on the south at Thompsons Point. On the west the well bedded shale-siltstone sequence lies above the rhyolitic tuff, probably unconformably but without the andesite unit intervening.

Further mapping is envisaged by the company to investigate the extension of the favourable geological horizon of the Hunter 18 prospect (see company reports 7696 and 7876) southeast along the Flat Top range. The domal structure in the Broadmount area was also considered to be of interest.

LOCALISED EXPLORATION/PROSPECTS

HUNTER 19 GRID

GEOLOGY - A southern extension of the Hunter 18 mineralised zone was gridded and mapped during the reporting period. This stratiform pyritised horizon was traced south from the Rockhampton Emu Park road along the Hunter 11 grid. The H18-H19 areas were found to be the only geochemically anomalous zones of any significance within the horizon.

The mineralised zone on H18 is reported to be a complex faulted anticline and it was believed that this complexity extended southwards to the H19 grid.

GEOCHEMISTRY - Hand auger b-horizon soil sampling was completed on a 25m line spacing. The results of analyses of these samples are summarised as follows:-

LEAD - The distribution of the values shows a much more discrete anomaly coincident with the copper anomaly but extending across the fault line to the south in two discrete trends.

ZINC - shows a broader distribution around the copper-lead anomaly and trends further south and southeast. Other localised zones of weak anomaly occur sporadically but appear insignificant.

SILVER - Two values of 3ppm coincide with the centre of the copper-lead-zinc anomaly. Two other values of 3ppm occur on the eastern end of line 5700N in andesite.

MANGANESE - Small zones of magnesite above 1000ppm occur coincident with the copper-lead-zinc anomaly, and also on the southeast of the area sampled at the time the report was written.

DRILLING -

Four percussion drill holes were put down on the geochemical anomaly. One hole was put down as a water supply.

The percussion drilling program confirmed the presence of a high anomalous mineralised zone within the alteration horizon with zinc values reaching 1.8%. It also showed the structural complexity in the area of the anomaly (i.e. faulted anticlinal structure). A more detailed discussion of the results of the drilling programme and the lithologies intersected in each hole is given in the report. Diagrams and cross sections of each hole are also provided.

GEOLOGY -

Regional mapping continued in areas of interest surrounding existing grids during the reporting period to decide whether further gridding was required.

LOCALISED EXPLORATION/PROSPECTS

HUNTER 15 GRID

GEOLOGY -

A small I.P. anomaly was discovered during a previous reporting period in the central part of the ATP about 2.5km southeast of Tungamull on the Rockhampton-Emu Park road (see company report 6720 & 6951). Infill gridding and mapping was complete in this area and the maps included in the report. No discussion was included in the report.

GEOCHEMISTRY -

A detailed I.P. geochemical survey was carried out over the grid during the reporting period and a small anomaly tested with a percussion drill hole. Drilling results showed that the discrete anomaly represented dispersion from the small gold-quartz veins which were investigated in the early part of the century.

GEOPHYSICS -

An I.P. survey was carried out over the Hunter 15 grid and a discrete anomaly was observed and investigated with a single percussion drill hole (see drilling below). Details of the survey are in company report 7876.

DRILLING -

Ash Tuff (12 - 27m) Pyritic Carbon-Rich Shale (27 - 63m)

Ash Tuff (63 - 81m) Coarse Ash Chloritic Tuff ( 81 - 132m) Ash Tuff (132 - 150m)

LOCALISED EXPLORATION/PROSPECTS

NORTH STAR - MT. NICHOLSON AREA

GEOLOGY -

GEOCHEMISTRY -

A ridge and spur soil sampling programme was conducted over the area during the reporting period. Detailed results are given in tables in the report and are summarised as follows:-

COPPER - values were generally low except for an a area near old mine workings where one high spot reaches 2000ppm.

LEAD - values correspond with copper value highs but Pb values are also anomalous in the north and centre of the area sampled reaching peaks of 1000 and 1400ppm.

ZINC - values were high in the area of the old workings, central and southern parts of the area sampled reaching a peak of 1900ppm.

DRILLING -

Following up from previous drilling of the Hunter 18 anomalous area, one percussion-diamond hole was drilled during the reporting period. Five percussion holes previously put down had intersected sub-ore grade mineralisation with the best intersection yielding 1.84% Zn (PDH2). PDH6/DDH1 was sited to test the mineralisation intersected in PDH2 at a depth of approximately 100m down dip from that intersection. The hole penetrated a different section of lithology suggesting that faulting or some other complication occurs along the section. This is shown particularly by a large section of andesite intrusive intersected near the top of the hole which has no equivalent mapped on the surface and within PDH2. Lower in the hole rhyolite tuffs are the predominant lithology, however, the thick section of alteration and mineralisation found in PDH2 was not intersected. Minor zones of weakly disseminated mineralisation and very localised irregular vein-type blebs of chalcopyrite were found.

A decision was made for Geopeko to dilute equity in the Berserker ATP.

SUMMARY:

GEOLOGY -

REGIONAL -

In previous reports (cr 8786 and 10594), regional mapping showed that the favourable horizon containing the Mt Chalmers mineralisation has been traced southwest from the Mt Chalmers mine through the Mt Nicholson - North Star areas to the Emu Park road. Consequently, detailed mapping of two locations in this area, North Star and Mt. Sleipner, was undertaken during the reporting period.

LOCALISED EXPLORATION/PROSPECTS

GEOLOGY -

NORTH STAR The strata at North Star dip gently westward and are folded about a synclinal axis down the western side of the gridded area, having a 5-100 plunge toward 3500. A pervasive foliation cleavage parallels the mean strike having an average dip of 800 E. A system of quartz veins is developed along the strike of this cleavage in some areas and these have been extensively exploited by early prospectors as a source of gold.

The stratigraphy of the North Star area is given in detail in the report and can be summarised as follows:-

Sericitic Altered Tuffs -

Oldest rocks at North Star and comprised of two members: the lower member is iron rich,variably chloritic and occasionally bleached, the upper member is moderately chloritic and cherty.

Substantially Unaltered Fine Grained Quart-Feldspar-Lithic Tuff -

Overlies the Sericitic Altered Tuff and is cross-cut by discontinuous dolerite dykes.

Andesite - Argillic Horizon overlying Tuff sequence with small feldspar and occasional quartz phenocrysts. Occurs on the eastern boundary of prospect.

A very fine grained rhyolite occurs along the western boundary of the andesite but its relationship is not understood.

All of these rocks are intruded by another andesite which is brecciated in places. The western margin of the gridded area is bordered by another andesitic unit which appears faulted into this position.

MT SLEIPNER AREA

The sequence at North Star is almost duplicated at Mt Sleipner. The pervasive foliation cleavage is not as persistent as at North Star and the quartz veining is not as well developed. A more detailed description is given in the report.

MINERALISATION/ALTERATION - sericitisation, chloritisation

GEOCHEMISTRY

- soil sampling -

NORTH STAR AREA

A grid was pegged over the North Star Prospect and soil sampling was carried out at 50m intervals along 200m spaced lines. A total of 318 samples were collected and analysed for Au, Cu, Pb, Zn.

Three areas of interest were detected. A discrete anomaly in the south-east where peak values of 660ppm Cu, 960ppm Pb, and 970ppm Zn were recorded, extended for 500m along strike with a maximum width of 250m. A somewhat less distinctive anomaly in the south-west where peak values of 250ppm Cu, 880ppm Pb, and 0.11% Zn were recorded, extended 1000m along strike with a maximum width of 400m. A third, though not clearly definable, anomaly extended across the north of the prospect where peak values of 0.2% Cu, 660ppm Pb, and 0.26% Zn were previously recorded by Geopeko.

To confirm the anomalous values, 38 rock chip samples were collected over the three anomalies. The maximum results obtained were 300ppm Cu, 0.18% Pb, and 460ppm Zn for the south-east anomaly and 30ppm Cu, 170ppm Pb, and 200ppm Zn for the south-west anomaly. No significant anomalies were obtained over the northern anomalies.

SUMMARY:

LOCALISED EXPLORATION/PROSPECTS

GEOLOGY -

Geological mapping on the ATP was continued around the mine workings of the Hidden King mine.

HIDDEN KING Stoping has occurred in thin shallow-dipping siliceous ash tuff and graphitic shale horizon that occur above a quartz feldspar porphyry and an andesite ?sill. The sill/ore sequence appears to occupy an axial position in a gently north plunging syncline. The sequence occurs within a broader sequence of rhyolitic, lithic, crystal tuffs. No production figures were available but sampling of material in wells of the stopes revealed maximum gold values of 0.29g/t indicating a very patchy distribution which has been completely removed.

GEOCHEMISTRY -

Soil sampling was carried out during the reporting period at New Zealand Gully and North Star grid.

NEW ZEALAND GULLY A grid measuring 450m x 300m was surveyed over the area of anomalous gold values detected in reconnaissance sampling. Line spacing was 50m and pegs were spaced 25m along lines. Soil samples (-80#) were taken at each peg and assayed for Au, Cu, Pb, and Zn. Rocks on the grid consist essentially of massive sericitic tuffs, probably stratigraphically equivalent to the sequence at Hidden King. Strongly silicified to vitric, pyritic tuffs ?overlie the sequence to the south.

NORTH STAR GRID Anomalous areas for Cu, Pb, and Zn were investigated to determine the cause of the anomalies. The areas were found to be associated with quartz veining with gossanous (after sulphide?) material. The base metal sulphides are thought to be due to base metal sulphides associated with the quartz veining. No gold values were detected in the soil geochemistry and no gold workings occur in the area.

SUMMARY:

GEOLOGY -

LOCAL -Geological targets were three small areas of Tertiary cover consisting of ferruginous sandstones, claystones and mudstones.

REGIONAL EXPLORATION

GEOLOGICAL MAPPING -A photogeological study was conducted by Hunting and Associates.

DRILLING -Ten holes totalling 448.5 m were drilled but failed to intersect any oil shale. Target depth of each hole was 60 m but only 2 holes reached this depth. Bore M.O.S. 2 bottomed in the upper Permian Back Creek Group. M.O.S. bottomed at 54 m in a quartzose, slightly ferruginous, gravelly-looking agglomerate. A similar lithology found as sub-crop was interpreted as Carmila beds. It was therefore interpreted that the Tertiary cover was very thin and downgraded the prospects of discovering significant deposits of oil shale. The ATP was relinquished on 31/8/1979.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -The ATP is one of two contiguous authorities (ATP 2055M and ATP 2140M) taken out as part of a regional search for subsurface Tertiary basins that might contain oil shale.

DRILLING -Three shallow rotary drillholes were drilled for a total of 99.5 m. A further seven rotary holes were drilled in October 1979 for a total of 331 m. None of these holes were drilled in the relinquished portion of the ATP.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -The rotary drilling programme has established the presence of a Tertiary basin beneath the alluvial flats in the northeast of the ATP but these sediments do not extend into the area relinquished, which comprises pre-Tertiary basement flanking the basin.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -To search for belts of possible Middle Devonian acid volcanics within the Connors Volcanics which may be prospective for Mount Morgan type gold-base metals mineralisation.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION -Part of ATP 2063M lies within the relinquished ATP 1444M and the reduced portion of ATP 1445M previously held by Marlborough Mining Syndicate.

GEOLOGICAL MAPPING -Exploration during the first six month period involved geological mapping aimed at outlining areas of an older series of volcanic rocks (Clements Creek beds) beneath the thick, previously undifferentiated sequence of the Connors Volcanics. These older volcanics and, to a lesser extent, some parts of local acid volcanics within the Permian Lizzie Creek Volcanics represent the main exploration targets within the authority.

Within the authority area, rocks assigned to the Connors Volcanics can be subdivided into two major stratigraphic units separated by a regional unconformity. The older unit comprises steeply dipping acid pyroclastics and bedded fine grained volcanic-derived sediments believed to be at least partly marine. This subunit is restricted to the southern part of the Connors Arch and is tentatively correlated with the Mount Holly beds and Capella Creek beds of the western Yarrol Basin. This older sequence is intruded by a series of granites and fine grained acid intrusives which are believed to represent a Middle Devonian intrusive event of comparable age to the Mount Morgan Tonalite.

The younger unit lies unconformably upon the older sequence and intrusives. Dips are comparatively shallower although some zones of steeper dips are present along the eastern margin of the Arch. This younger unit is intruded by Middle Carboniferous (305my) granite near Burwood (north of ATP 2063M) and is correlated with the Upper Devonian - Lower Carboniferous acid and intermediate volcanic sequence of the western Yarrol Basin.

The younger sequence makes up the bulk of the outcropping Connors Volcanics in the southern Connors Arch, and due to its resemblance to the type area of Connors Volcanics (25km north of the ATP area) the term Connors Volcanics is reserved for this upper unit. A new name the Clements Creek beds is introduced for the older sequence.

Within ATP 2063M the Clements Creek beds comprise blue-white weathering, finely banded silicified fine acid tuffs associated with black quartz-feldspar porphyry tuff or dacitic crystal tuff.

The Connors Volcanics comprise acid and intermediate lavas and pyroclastics. Prominent interbedded conglomerates are developed toward the base of the unit. The volcanics are characterised by rapid lateral variation and interfingering between acid and intermediate volcanic facies. Lithologies in the Connors Volcanics south of the Bruce Highway are similar to those in the Dee Volcanics in the western Yarrol Basin.

The Lower Permian Carmila beds extend up the eastern flank of the Connors Arch along the eastern boundary of ATP 2063M. Lithologies include grey and grey-green acid lapilli tuff, volcanic conglomerate, bedded volcanolithic sandstone, siltstone and tuffaceous siltstone.

GEOCHEMISTRY

- stream sediment sampling -Some of the authority area was covered by a stream sediment sampling program performed by the Marlborough Mining Syndicate in late 1974. No anomalous values were reported from this area. Geological mapping during the present survey has shown that most of the samples collected in the 1974 survey were taken over the unprospective Connors Volcanics and Lizzie Creek Volcanics. The more prospective Clements beds occupy only a small area in ATP 2063M. Stream sediment sampling during the current survey has been confined to the small areas of outcropping Clements Creek beds.

Sampling conducted in 1974 indicated extremely low values of lead and zinc within areas of Connors Volcanics. Comparatively high values were recorded over outcrop areas of Clements Creek beds which produced 41 samples with zinc higher than 90ppm. However, copper values were often higher over the Clements Creek beds.

Stream sediment sampling in the ATP during the reporting period was confined to areas of outcrop of the Clements Creek beds. Results were not available at time of writing and are to be included in the next six-monthly report.

- soil sampling -Soil sampling was carried out over an area of altered pyritic acid volcanics in the Lizzie Creek Volcanics 5km east of Clarkwoods homestead. The altered volcanics are finely banded in places and associated with some red jaspers. Minor galena is visible in some fresh pyritic samples. Results are included in the relinquishment report (CR 7959). No significant metal values were returned.

-rock chip sampling - Rock chip sampling was conducted over the altered volcanics in the Clarkwoods area. Analyses of four samples of fresh pyritic acid volcanics, some of which contain galena, indicated maximum lead values of 450ppm and no other significant metal values.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE - It was concluded that the Connors Volcanics were quite barren and the tenement was relinquished.

ATP/EP No.:ATP 2376M COMPANY HOLDING TITLE:Getty Oil Development Company COMPANY SUBMITTING REPORT:Getty Oil Development Company DATE GRANTED:27/3/1980 PERIOD: 1:100 000 SHEET NAME(S):Rookwood (8851) 1:250 000 SHEET NAME(S):Duaringa (SF55-16) LOCATION:80 km west of Rockhampton MINING DISTRICT: MINES/PROSPECTS:Rookwood Grid EXPLORATION TARGETS\MODELS:Volcanogenic massive sulphide mineralisation.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -The area was selected after a review of published literature and open file reports based on exploration work carried out by Bligh Oil and Minerals N.L. on ATP 654M in 1970. Bligh Oil located a number of thin gossans in the Lower Permian Rookwood Volcanics which were never drilled.

Getty Oil concluded that further exploration in the area was warranted because of - (1) the Rookwood gossans could reflect volcanogenic base metal mineralisation, (2) the lack of stream sediment cover of Rookwood Volcanics to the south of ATP 654, and (3) the possible metallogenic significance of mineralisation close to the Rookwood Volcanics/Boomer Formation contact.

GEOLOGY -

REGIONAL -The major rock units within the immediate vicinity of the ATP are Rannes beds, Rookwood Formation (both lower Permian), Boomer Formation (Upper Permian) and an unnamed Upper Permian adamellite intrusive near Rookwood homestead.

LOCAL -The Rannes beds crop out only in the northwest of the ATP. The predominantly sedimentary sequence consists of mudstone, siltstone, greywacke and conglomerate with minor acid to intermediate volcanics and volcanic agglomerate.

Within the ATP, the Rookwood Volcanics are comprised predominantly of vesicular and fine- to coarse- grained andesite and andesitic lapilli tuff. There are minor outcrops of variolitic and tholeiitic basalts. Base metal mineralisation is associated with rhyolite intrusives within the volcanics.

The Boomer Formation is represented in the eastern portion of the ATP by volcanolithic sandstone, siltstone, carbonaceous claystone and conglomerate.

Adamellite, diorite and gabbro intrude the Rookwood Volcanics near Rookwood Homestead. These intrusives have been dated isotopically at about 240 million years.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION -The northern parts of the ATP comprised parts of earlier ATP's 786M and 654M held by Bligh Oil and Minerals N.L. in 1969-70. Exploration during that period included-

(1) Reconnaissance stream sediment sampling at approximately 2 samples per square mile.

(2) Follow-up stream sediment sampling over anomalous areas.

(3) Ridge and spur (soil?) sampling on anomalous drainage systems.

(4) Detailed geological mapping.

(5) Grid soil sampling at Balcomba Creek and Rookwood Homestead.

(6) Costeaning and rock chip sampling of geochemical anomalies within the Rookwood Homestead anomaly area.

(7) IP survey over the Rookwood Grid.

A stream sediment survey largely to the north and northeast defined a number of low order anomalies in four locations. Only one anomaly near Rookwood Homestead was deemed to be of further interest. At this locality, a series of thin gossanous rhyolite horizons in the Rookwood Volcanics were found associated with a few shallow pits containing copper-stained boulders. Trenching and soil sampling indicated that three main gossans are present in an area about 500m x 600m. The gossans appear to be thin (up to 5 m, but generally < 2 m) and east-dipping. Copper and zinc values range up to 1% but average less than 0.5%. An IP survey indicated a weak anomaly over the widest gossanous unit. After detailed mapping, these strong anomalies were linked to black or grey shales of the Boomer Formation, apparently overlying or faulted against the Rookwood Volcanics. Although further detailing of the IP was recommended, no further work was carried out and the title was surrendered on the basis that the IP survey had not indicated the presence of a large, buried sulphide deposit.

LOCALISED EXPLORATION/PROSPECTS

Rookwood Homestead Area-

GEOLOGY -A new metric grid was set out using the same orientation as the Bligh Oil and Minerals imperial grid. The grid area covers poorly outcropping Rookwood Volcanics comprising jointed and faulted andesitic flows with thin (to 1 m) ferruginous rhyolite intrusives. The rhyolites are gossanous in part, and occupy shear or fault zones in the andesites. These zones dip steeply to the east (60o)) and truncate poorly developed flow-banding in the andesites (35o easterly).

The development of gossans in the rhyolites is irregular producing scattered outcrop. Highest assay values were recorded from chip samples in costeans in the gossanous rhyolites and immediately adjacent sheared andesite. Typical assay values are 2400 ppm Cu, 600 ppm Pb, 880 ppm Zn, 2 ppm Arsenic. As indicated by reconnaissance sampling Ag and Au values are insignificant. The primary sulphides are pyrite with minor chalcopyrite and sphalerite.

Rocks in the area surrounding the gossans are silicified and epidotised andesite. Because of poor outcrop and extensive soil cover, alteration zones were not mapped.

GEOCHEMISTRY -31 rock chip samples were collected from the Rookwood area, and 14 of these were analysed for Cu, Pb, Zn, Ag, Au. Analyses revealed that copper is the dominant metal with minor zinc and less lead. Gold and silver values were insignificant.

GEOPHYSICS -A magnetic survey using a Geometrics Cr 816 Magnetometer, and a radiometric survey using a Geometrics GR 310 Gamma Ray Spectrometer were carried out. The radiometrics revealed a featureless picture over the grid. Minor magnetic anomalies were found but ground evaluation revealed these to be ferruginous andesites.

Southern half of ATP 2376M

GEOCHEMISTRY - A stream geochemical survey was carried out over the Rookwood Volcanics and Boomer Formation on the southern half of the ATP, on area not covered by previous surveys. The survey covered approximately 120 km2 and 210 minus 80 mesh sediment samples were collected and analysed for Cu, Pb, Zn and As. With the exception of some slightly elevated Zn values (100-200 ppm) in the eastern portion of the ATP, all values were very low. The anomalous area is underlain by the volcaniclastic sandstones of the Boomer Formation and jointed white cherty rhyolite. The rhyolites are considered to be the source of the zinc anomalies.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -The mineralisation and alteration in the Rookwood Grid area are believed to be related to Upper Permian intrusives near Rookwood Homestead. Shear zones may have provided a permeable area in which solutions were able to deposit mineralisation. The original VMS model was abandoned.

Drilling was not justified.

SUMMARY:

REASON FOR ACQUISITION OF TITLE- Due to the presence of outcropping Tertiary sedimentary rocks, the ground was taken up as an oil shale prospect.

GEOPHYSICS

A gravity survey was completed over the area of the ATP. A total of 65 Bouguer gravity stations have been established over, and adjacent to the ATP. All new data have been tied into the National Grid through ties to previously established stations which form part of the reconnaissance gravity survey of Australia conducted by the BMR. The resultant gravity map over the ATP shows an anomaly of 15 milligals relief. The interpreted depth to Devonian-Carboniferous or Permian basement rocks depends on the density contrast with the Tertiary and younger cover rocks. Assuming a density contrast of 0.2, 0.3 and 0.4, the interpreted thickness of younger rocks can be 1800, 1200 and 900 metres respectively.

DRILLING -Three vertical drillholes were drilled for a total of 445 m. The holes were sited along a southeasterly trending section-line across the Tertiary rocks. The holes were a combination of open hole and HQ core drilling. Geological logs are provided in the report. In summary, the drilling confirmed the presence of a Tertiary sedimentary basin containing siltstones, sandstones and claystones.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -No oil shale was observed in any of the Tertiary sediments, and this fact combined with the limited areal extent of the basin led to the conclusion that further exploration for oil shale was not justified and the ATP was relinquished.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -The ATP was taken out to resolve the oil shale potential of the Tertiary Redbank Basin.

GEOLOGY -Geological investigations of the Redbank area were carried out by logging drill core and chip samples, combined with a limited amount of geological mapping. Initially it was believed that the Redbank Basin extended the full length of the ATP, however drilling indicated that the basin occupies only the northern half of the ATP. The northern Redbank Basin appears to be an asymmetrical, fault- bounded, westerly-thickening basin or half-graben, while to the south it may change to a fault-bounded (western edge) shallow basement syncline. Faulting is present in the surrounding basement rocks but no mappable features (on air photos or ground) could be identified in the Tertiary.

DRILLING -Two cored and two non-cored holes were drilled in the Redbank area to intersect pre- Tertiary basement. The average hole depth was 211 m. Drilling results indicate the existence of a shallow, fault-bounded Tertiary basin in the north. South of this area, no Tertiary sedimentation is evident, the area comprising mainly Quaternary sediments directly overlying Permian basement. The northern portion of the ATP shows a somewhat shallow Tertiary cover to the east becoming rapidly deeper towards the down-faulted western flank.

GEOPHYSICS -A resistivity survey was conducted concurrent with drilling. The high resistivity values recorded led to the interpretation that there is negligible Tertiary sediment cover in the southern section of the Redbank area. This confirms the result from drillhole CR4 which passed through Quaternary alluvium into pre-Tertiary basement.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -No potentially economic oil shale intersections were encountered during exploration. Minor seams were intersected but gave very low yields. No other minerals of significance were encountered and the area was relinquished.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -This area was selected for detailed exploration following regional geochemical sampling for base and precious metals in the Upper Palaeozoic sequences of the New England Orogen. Sampling in the Britannia Mine area indicated that there was potential for both low grade disseminated precious metal mineralisation and stratiform base metal mineralisation in the Berserker beds.

GEOLOGY -

LOCAL -See under GEOLOGICAL MAPPING in CURRENT EXPLORATION section of this summary.

MINERALISATION -Apart from minor base metal sulphide mineralisation occurring in mine dumps from the Britannia area no mineralisation of any significance has been recognised.

Fine disseminated pyrite and blebs of pyrite in narrow quartz veins are a feature of fine-grained to microcrystalline siliceous cherty argillites and siltstones forming distinctive horizons within the Berserker beds.

Between Planted and Sandy Creeks a variably gossanous (silica-haematite-goethite-carbonate) and jasper- rich horizon may represent a brecciated sinter. Analysis of selected specimens from this, and similar gossanous zones indicate that apart from isolated weakly anomalous arsenic and gold values and high nickel values related to garnierite, no base metal enrichment is present.

ALTERATION - No evidence of hydrothermal alteration was observed in the Ridgelands Granodiorite. Weakly developed chlorite-sericite deuteric alteration was observed in granophyric textured felsic rocks of this pluton. The general lack of alteration, significant fracturing and quartz veining in this unit indicates that it has little potential for hosting significant base or precious metal mineralisation.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION -Modern exploration of the district commenced in 1964 when BHP conducted a regional search for Cu, Ni and Cr in the serpentinised ultramafics of the Marlborough and Coastal Blocks. Although BHP recognised sporadic local nickel enrichment in laterites, most prospects are small in size and of low grade. A total of 29 million tonnes of mineralisation grading 1.28% Ni at 1% Ni cutoff has been demonstrated to occur at four localities; Brolga, Canoona, South Slopeaway and Coorumburra.

Although BHP conducted a large scale aeromagnetic survey of the region and performed adequate regional mapping, no systematic detailed geochemical or geological work was carried out away from the ultramafics. Little attention was paid to the base metal potential of the Palaeozoic sequences in the Canoona District.

Minor amounts of chromite have been won from numerous small deposits within the Marlborough ultramafics. The large lode north of Princhester Creek is estimated to contain at least 40,000 tonnes of low grade (28% Cr2O3) mineralisation in the form of disseminated crystals and larger irregular masses of chromite.

IN 1974 Esso Australia Limited conducted base metal exploration within ATP 1362M. Exploration was concentrated on the search for replacement and contact pyrometasomatic deposits around the margins of the Ridgelands Granodiorite. Anomalous zones delineated by a detailed aeromagnetic survey were found to be unrelated to base metal mineralisation and the area was relinquished.

CURRENT EXPLORATION

GEOLOGICAL MAPPING -Reconnaissance mapping was conducted at 1:31 000 scale.Units defined within the ATP include undifferentiated Lower Palaeozoic metamorphics, Devonian strata, undifferentiated Lower Carboniferous volcaniclastics and sediments, Permian Berserker beds, ultramafics and Ridgelands Granodiorite.

GEOCHEMISTRY

- stream sediment sampling -A stream sediment survey covering the entire ATP was conducted during the first six-month period of tenure (CR 9889). A total of 456 samples collected. Sample density varied from 4 samples per sq km over well drained Berserker beds, to 2 samples per sq km over metamorphic and intrusive rocks. Samples were analysed for Cu, Pb, Zn, Ag, As, Ni and some for Sb. The presence of serpentinite lenses within the Palaeozoic sequences has complicated the analysis of drainage anomalies. Nickel has been used as a discriminator here, in that samples with nickel values greater than 400 ppm are considered to have been largely derived from serpentinite. Seven distinct anomalous zones were defined within and adjacent to the ATP and are discussed in the report.

During the second six-month period of tenure (CR 9890) detailed stream sediment sampling of anomalous zones (as defined by reconnaissance sampling in the previous period) involved the collection of a further 271 samples at a density of 6-8 samples per sq km. Rock chip sampling was also conducted over the anomalous areas. In general the programme provided confirmation and redefinition of the anomalism.

Details of the individual geochemical anomalies are outlined in the appropriate section of the CR 9890.

Soil sampling - During the second six-month period of tenure (CR 9890) a 1600 x 2600 m grid was laid over the Britannia Mine area and subsequently soil sampled. A total of 340 samples were collected. Weak As anomalism (10 ppm As) with locally associated low Cu, Pb, Zn and Au values occurs in four broadly strike orientated zones within the grid. Arsenic appears to be the most useful pathfinder element for gold in this environment.

This geochemical work showed that no substantial base metal halo exists around the gold mineralisation, and that stratabound base metal and precious metal mineralisation is probably not significant in this area.

GEOPHYSICS

- ground surveys -A ground magnetic survey was conducted to locate unexposed ultramafic contacts and to define poorly outcropping serpentinite lenses within the Berserker beds. Magnetic readings were also taken on a grid laid over the Britannia Mine.

Results of the magnetic survey clearly outline the major serpentinite body that outcrops along the first and second Sugarloaf hills. This body appears to be displaced along a NW trending zone which corresponds with a photolinear and suspected dextral fault zone. Other features highlighted by the magnetic survey include minor anomalies which are thought to correspond with narrow lenses of serpentinite parallel to the strike of the surrounding Permian rocks.

The magnetic survey also highlights significant magnetic variations within the Berserker beds.

PETROLOGY - Twenty petrological descriptions are presented in the report.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -After all geochemical anomalies had been assessed the ATP was relinquished.

SUMMARY:

GEOLOGY -

REGIONAL - The Yaamba Oil Shale Project area covers three oil shale basins, the Yaamba, Rossmoya, and Herbert Creek. These basins belong to a group of fault controlled basins extending some 600 km, from Gladstone in the south to Proserpine in the north. Other oil shale basins in this group occur at Rundle, Stuart, Condor, and Nagoorin.

The system of basins developed as a result of Late Cretaceous and Early Tertiary block faulting within a basement of Palaeozoic and Mesozoic sediments, volcanics and intrusives. The three basins in the project area are completely covered by Quaternary alluvium up to 46 m thick. Both the Yaamba and Rossmoya Basins are closely associated with Upper Cretaceous basalts which subcrop beneath much of the alluvial cover adjacent to the basin. These basalts form basement to the Tertiary sequences in both basins.

The Yaamba and Rossmoya Basins are separated by an uplifted north-westerly elongated block of Palaeozoic acid and intermediate volcanics and serpentinite intruded by diorite and feldspar porphyry. The Yaamba Basin sequence is faulted against these rocks along its north-eastern and northern margins but overlies the Cretaceous basalts along its south-western and eastern margins.

In the Herbert Creek Basin, no basalts or other volcanics had been found in association with the Tertiary sequence. This sequence probably overlies a basement of Palaeozoic or Mesozoic granite which crops out over a large area to the east of the basin. Palaeozoic acid volcanics, sediments, metamorphics and serpentinite, intruded by stocks of granite, crop out in the high hills along the western margin of the basin.

Reports 11179 and 12140 detail logs of rotary drillholes sunk within relinquished areas of ATP 2673M.

Most of the reports on this project are still confidential and cannot be incorporated into any publications.

SUMMARY:

REASON FOR ACQUISITION OF TITLE - To examine areas of undifferentiated acid volcanic rocks to determine their potential for massive sulphide mineralisation of the Mount Chalmers type.

GEOLOGY -

REGIONAL - Undifferentiated Siluro-Devonian rocks in the area consist mainly of acid to intermediate tuffs and sediments with prominent limestone interbeds. The sediments have a pronounced slaty cleavage and are lithologically very similar to the Lower Devonian Mount Holly Beds to the south.

The Permian Ridgelands granodiorite intrudes these rocks in the SE of the ATP; gabbro intrudes in the north-central part of the ATP. Carboniferous rocks occur on the west; ultrabasic rocks of the Marlborough Complex occur in the north of the ATP.

LOCAL -

MINERALISATION/ALTERATION - Secondary copper mineralisation observed in small shaft sunk on a skarn (Ellrott Skarn).

LOCALISED EXPLORATION/PROSPECTS

GEOLOGY -

GEOCHEMISTRY - Three rock chip samples were collected from a small shaft sunk on a skarn containing secondary copper mineralisation. Assay values (determined by Mount Morgan Ltd) returned:

Sample Depth Au g/t Ag g/t Cu % Pb ppm Zn ppm WO3ppm 41197 0-2 m 1.50 14.0 4.76 20 460 1350

The significant gold, silver and copper assays warranted further investigation. The tungsten assays were suspect as no scheelite was observed when specimens were examined under ultraviolet light.

GEOPHYSICS - A tape and compass magnetic survey was carried out over the Ellrott Skarn area. Small discrete magnetic highs are associated, but not coincident, with the Ellrott Skarn.

DRILLING - Two percussion drill holes were drilled to test the magnetic anomalies. C1 was drilled to 90 m to test the westernmost anomaly. It penetrated dolomitic siltstone and biotite gneiss in its upper portion and was completed in granodiorite. No significant mineralisation was intersected.

C2 was drilled to 150 m to test the magnetic anomaly associated with the Ellrott Skarn shaft. It intersected various types of dolomitic hornfelses over the entire length. A small zone of pyrite mineralisation was noted between 95-105 m. No significant mineralisation was detected.

Logs of the drill holes with analytical values are included in the report.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE - No significant mineralisation was detected, therefore the area was relinquished.

REASON FOR ACQUISITION OF TITLE - The area was taken out with the intention of delineating magnesite and other mineral occurrences in the area.

GEOLOGY -

LOCAL - The area covers two belts serpentinised ultramafic rocks (serpentinised Harzburgite). Minor Permian granodiorite intrusives occur in the area. Much of the area consists of Quaternary alluvial flats.

MINERALISATION/ALTERATION -

REGIONAL EXPLORATION

PREVIOUS EXPLORATION - Reference is made of chromite, magnesite, and chrysotile asbestos occurrences in the area (no details given).

LOCALISED EXPLORATION/PROSPECTS - During the first six month period, reconnaissance work was undertaken mainly within the eastern section of the area. This work involved identifying rock types and delineating magnesite and other mineral occurrences in the area.

GEOLOGY - Areas which contain magnesite veins and nodules were delineated, as well as areas of silica alteration, and metasomatic and silica alteration associated with a gabbroic intrusion. Surface samples of magnesite and country rock were collected for analysis and interpretation.

Magnesite was found to be widely distributed, but no major target could be defined for follow-up work. The magnesite and magnesite/country rock samples indicated a high level of calcium. Silica contamination in the magnesite nodules was noted. The calcium and silica content was perceived as a problem.

The few chromite occurrences were regarded as not significant during the exploration period.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE - The area was relinquished because the magnesite was thought to be either too impure or too disseminated to warrant further exploration, especially when purer magnesite was available at the surface in adjoining ATP 3003M to the west.

SUMMARY: (extracted from CR 10433 summary)

REASON FOR ACQUISITION OF TITLE - To check for any relationship between the previously known copper anomalies and old gold workings.

GEOLOGY -

REGIONAL -

LOCAL - The ATP is located in the Craigilee Anticline which consists of a core of Upper Silurian - Lower Devonian volcanics unconformably overlain by Lower Carboniferous sediments of the western Yarrol Basin.

The Upper Silurian - Lower Devonian sequence consists predominantly of tough, massive, greenish grey, silicified fine grained tuffs and flows described as 'keratophyre'. These keratophyric rocks include sequences of very thin bedded, cherty tuffaceous siltstones and mudstones. Sequences of reddish brown andesitic lavas, lava breccias and tuffs occur in the sequences, and limestone lenses occur southeast of Melrose Homestead.

The lower Carboniferous sediments that unconformably overlie the Siluro - Devonian rocks in the southeast of the area consist of indurated mudstone and siltstone, sandstone and oolitic limestone.

MINERALISATION/ALTERATION - Gold mineralisation at Mt Cassidy; nearby geochemical Cu anomalies associated with andesitic volcanics. They appear to be unrelated.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION - Geochemical anomalies were outlined in 1972 by International Nickel Australia Ltd (ATP 1007M).

LOCALISED EXPLORATION/PROSPECTS

GEOLOGY - A base map from 1973 air photos at 1:32 000 was prepared; field inspections were carried out to determine relationships between Mt Cassidy gold workings and the geochemical copper anomalies.

GEOCHEMISTRY - Geochemical anomalies outlined in 1972 by International Nickel Australia Ltd (ATP 1007M) were assessed. Threshold (x + 2s) values of 125 ppm for Cu, 54 ppm for Pb, and 108 ppm for zinc were determined. Additional geochemical soil samples and rock chip samples were collected and analysed for Cu, Pb, Zn, Au, and Ag.

A belt of anomalous copper values was defined in the area east of the Mt Cassidy gold workings. This anomaly follows a belt of reddish brown andesitic lavas and pyroclastics (Cu values commonly between 200 and 300 ppm) that continue to the southwest of the ATP where they are reflected by other drainage anomalies of Cu. These volcanics are strongly hematitic and both the drainage and soil anomalies reflect the high Cu background content of the rocks. No visible sign of Cu mineralisation was seen in these andesitic volcanics in outcrop or creek float. No detectable gold was found in these andesitic volcanics and their derived soils, except for one sample from the base of the andesitic sequence which contained 0.1 ppm gold. However, detectable gold was found in a silicified fine grained pyritic keratophyre dyke in the andesitic volcanics (Cu 80 ppm).

The old gold workings at Mt Cassidy are very small and occur in silicified pyritic fine grained (?keratophyric) intrusives that are aplitic in places, within a sequence of pyritic cherty (?keratophyric) lava and fine grained tuffs and tuffaceous sediments that are locally very thin bedded. Samples of the pyritic material from the old workings contain detectable gold (4 samples at 0.02, 1.5, 17.7, 0.2 ppm), whereas other metal values are very low, particularly Cu (2 ppm or less).

The gold mineralisation at Mt Cassidy appears to be related to shallow sub-volcanic keratophyric intrusives within the cherty pyritic sequences. This gold mineralisation is divorced from the geochemical anomalies reflecting the high Cu background of the andesitic sequences which may reflect the low grade native copper type mineralisation in the altered andesites.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -

GEOLOGY -

REGIONAL - The oldest rocks in the area are the Siluro-Devonian rocks which occur mainly in the south-western part of the ATP with minor occurrences in the northern part. These rocks consist of dacitic crystal tuff, vitric tuff, andesitic tuff, mudstone and limestone.

The Siluro-Devonian rocks are unconformably overlain by undifferentiated Lower Carboniferous rocks. These younger rocks occur mainly in the southern and south-western part of the ATP with minor occurrences in the north-western part. Lithologies consist of siltstone, mudstone, tuff, tuffaceous sandstone and conglomerate. The finer grained sediments are dominantly tough, cherty, banded mudstones with minor soft fissile mudstone and interbedded vitro-tuffs. The sandstones are commonly medium to coarse grained and are associated with granite conglomerate containing bands of rounded pebbles. Some of the sandstones contain a high percentage of tuffaceous material, whereas others consist almost entirely of andesitic material.

Rocks of the Lower Carboniferous Rockhampton Group conformably overlie the undifferentiated Lower Carboniferous unit. Lithologies in the Rockhampton Group include siltstone, mudstone, tuff, tuffaceous sandstone, conglomerate, and oolitic limestone. The oolitic limestone is a characteristic lithology in the unit. In the lower section of the unit mudstone dominates over sandstone and is highly silicified, whereas in the upper section the sandstone becomes more abundant and the mudstone is less silicified. The grains consist generally of equal proportions of tuff and feldspar. Massive coarse grained sandstone and conglomerate beds form a large part of the sequence. The oolitic limestone indicates shallow water deposition whereas the rhythmically bedded unfossiliferous sandstone and mudstone sequences suggest deep water deposition.

A small section of the Upper Carboniferous Neerkol Formation occurs towards the north-western part of the ATP. It consists dominantly of fine grained silty sandstone, coarse sandstone, conglomerate and minor limestone. The unit is similar to the Rockhampton Group and appears to disconformably overlie it. The main difference is the greater abundance of quartz in the sandstone layers. The sandstones are fine to medium grained and occur as thin interbeds in the mudstones. Fossils are abundant in this unit (suggest shallow marine environment).

During the Permian, the Palaeozoic sediments were intruded by the Ridgelands Granodiorite (outcrop in the NE part of the ATP). The granodiorite is thought to have introduced the mineralisation into the area.

MINERALISATION/ALTERATION - Two styles of gold occur in the area: 1) lode gold which appears to have been introduced by late stage fluids associated with the granodiorite intrusion 2) ancient deep lead gold in Mesozoic sedimentary rocks

LOCALISED EXPLORATION/PROSPECTS Gold was first discovered in the alluvials in the Morinish area in 1866. Within the ATP three main gold areas were of interest:

1) WELCOME MINE (MORINISH MINE) - Mineralisation occurs within the undifferentiated Lower Carboniferous tuffaceous rocks. The Welcome Reef was described as a quartz reef containing gold, pyrite, arsenopyrite, minor galena, and sphalerite in a fine grained greywacke. The gold appears confined to narrow reefs contained within silicified tuffs and chert, as well as greywacke.

The general Morinish area was explored by ESSO Minerals in the early 1970's and later by Mineral Deposits in the late 1970's. ESSO carried out a geochemical program which delineated an anomalous area over a silicified brecciated ridge in the NE corner of ATP 2862M. An IP survey was conducted with follow-up drilling, however, no economic mineralisation was detected. Mineral Deposits followed up ESSO's work but also without success.

2) ALLIANCE MINE - Mineralisation occurs within breccias and shear zones in the Siluro-Devonian andesites and limestones. The gold occurs in a quartz reef which also contain various copper ores. The main shaft is situated at the intersection of two or more breccia zones.

3) HUNTER VALLEY LEAD - Placer gold occurs in the Mesozoic sedimentary wash of probable Cretaceous age, overlain by basalt and rhyolite. The wash is 3 - 4 m thick and consists of pebbles of chert, shale, quartz and rare cobbles of igneous rocks up to 0.15 m in diameter, set in a cemented gritty matrix. The gold, which is patchy in occurrence, was reported to occur only in the basal 0.6 m. No gutters were defined. The wash zone which dips to the north and north-east at 14 - 40° and unconformably overlies the basement, was defined over a length of about 0.7 km.

Old workings in the Hunter Valley Lead area include: Newman's No 1 Shaft, Newman's No 2 Shaft, Thomsons Mine, as well numerous shallow pits near the up-dip limit of the lead.

Although no further work was done on the ATP, further exploration was recommended in CR 10644 is as follows: - concentrate on the Morinish 'Deep Lead' areas and Alliance Mine

- in the Morinish 'Deep Lead' areas: - construct a 1:2 000 map of the area of the potential lead - limited resistivity profiling to locate the centre of the lead - costeaning in the upper parts of the lead to determine its extent, evaluate the lithologies present, and determine the nature of the lead - possible drilling to determine the central part of the lead

- in the Alliance Mine area: - structurally map the area - sample and analyse breccia and shear zone within the existing adit and old workings

Mineralisation in the Welcome Mine appears too small to have commercial potential.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE - No reasons were given for relinquishing the ATP.

SUMMARY:

REASON FOR ACQUISITION OF TITLE - Exploration mainly for placer gold, also looked at local lode gold potential.

GEOLOGY -

MINERALISATION/ALTERATION - Alluvial gold occurs in the Native Cat area with gold values of about 0.75 g/m3 in reserves of 60 000 to 100 000 m3. The alluvial gold appears to be derived from the gold mineralisation associated with the intrusion of diorite into the Native Cat Andesite.

LOCALISED EXPLORATION/PROSPECTS - Alluvial deposits in the creeks in the area were prospected using a gold panning dish and a small portable dry blower (16 bulk samples were tested). Areas of old diggings were also defined and assessed where possible. A geological map over the area was produced from 1:25 000 and 1:30 000 black and white air photos.

GEOLOGY - The alluvial gold appears to be derived from the gold mineralisation associated with the intrusion of diorite into the Native Cat Andesite. The gold mineralisation, it seems, occurs in association with iron and minor copper sulphides in chloritic, altered rocks within the andesites adjacent to the diorite contact. The alluvial gold is coarse grained in nature reflection its original grain size. As the alluvial deposits are not high it is assumed that the gold is either widely disseminated through the original host rock, or confined to narrow, rich zones. No mineralised quartz was found in the Native Cat area and no quartz pebbles were observed in the gold bearing alluvials. Rock chip samples from the hydrothermally altered andesites near the diorite intrusion returned values at 0.1 ppm with on at 0.5 ppm. There does not appear to be any potential for economic hard rock gold mineralisation. However, all the alluvials derived from the andesite/diorite are prospective.

GEOCHEMISTRY - Rock chip samples from the hydrothermally altered andesites near the diorite intrusion returned values at 0.1 ppm with on at 0.5 ppm.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE - There does not appear to be any potential for economic hard rock gold mineralisation, but all alluvial deposits from andesite/diorite contact must be considered prospective. Although no reason for the relinquishment was stated, mention was made of the scarcity of surface and underground water.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -To search for magnesite in an area of known ultramafic rocks.

REGIONAL EXPLORATION

Field reconnaissance was carried out in the search for magnesite occurrences. The most prospective area was around the old "Jack Young" leases adjoining the Bruce Highway. Chromite was noted in several places within the authority.

LOCALISED EXPLORATION/PROSPECTS

GEOLOGY -Six rock samples were submitted for petrological examination

DRILLING -Four costean sites were drilled using a percussion air-trac rig to determine the depth to which magnesite would be encountered. Each hole revealed traces of magnesite down to the 15m maximum penetration of the rig. Each site was pattern drilled and fragmented to a depth of 5m using explosives. Costeans were then dug using a track mounted excavator to depths of about 5m. Bulk magnesite samples were transported to Rockhampton for beneficiation tests. It was deemed that the finely porous nature of the magnesite particles prevents effective gravity separation. Flotation or tabling is possible but would require fine grinding. Optical sorting is another possibility but would require high capital expenditure.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -It was considered that the minerals found within the authority, in particular magnesite and chromite, do not warrant further expenditure and it was therefore recommended that the tenement be relinquished.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -The area was chosen to incorporate areas where ultramafic rocks had been mapped.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION -Magnesite is noted in available literature and the old workings of the Mount Morgan magnesite mine are shown on the Port Clinton 1:250 000 Sheet.

Chromite is known to occur throughout the serpentinite and alluvial areas. The occurrences are marked and described in the BHP final reports on ATP 1753 (CR's 6641) and ATP 1754M (CR 6423).

RECONNAISSANCE- The ATP was traversed on foot, by motor vehicle and by light aircraft. Most traverses were designed to locate magnesite occurrences but rock sampling was also performed.

LOCALISED EXPLORATION/PROSPECTS

Magnesite occurrences are noted in this report. The most prospective area is that of the old "Jack Young" leases adjoining the Bruce Highway on the property "Lowville". Chromite was noted in small quantities in several locations.

GEOLOGY -Petrographic examination of six samples collected from the project area are reported on in an Appendix to the report.

DRILLING -An attempt was made to assess the quality, continuity and depth of the magnesite which crops out strongly in the old "Jack Young" leases south of the Bruce Highway at Princhester, on the property "Lowville". Four (4) costean sites were drilled by percussion to determine the depth at which magnesite would be encountered. In each case, traces of magnesite, variably contaminated, were indicated at depths up to the maximum penetration of the drill stem (15m). Each site was pattern drilled and material fragmented to a depth of 5 m using explosives. Costeans were subsequently dug to 5 m depth using an excavator. Magnesite was trucked to Rockhampton, crushed and screened and then forwarded to the Kaiser Refractories laboratory in Oakland California USA and AMDEL Adelaide for further attempts at beneficiation. The results were largely unsuccessful. The finely porous nature of the magnesite particles prevents effective gravity separation. Flotation or tabling are possible methods of beneficiation but would require fine grinding. Optical sorting is another possibility but would require high capital expenditure.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -The area was selected because of its content of ultramafic rocks believed to be prospective for the target minerals.

REGIONAL EXPLORATION

RECONNAISSANCE -Prospecting was limited to foot traverses in the central part of the Authority, motor vehicle traverses in the central and southern areas and visual prospecting and colour air photograph coverage from light aircraft. Some limited sampling of surface magnesite outcrop was carried out.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -Analysis of the samples collected revealed that the magnesite within ATP 3004M has silica and lime contents far too high for refractory use. ATP 3004M was relinquished and exploration efforts were to be transferred to the adjoining ATP 3003M which from initial investigations showed more promise.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -The area was applied for to investigate the base metal (volcanogenic massive sulphide) and gold potential of the Connors Volcanics.

GEOLOGY -

REGIONAL -The ATP was located within the Connors Arch comprising the Devonian-Carboniferous Connors Volcanics, Lower Permian Carmila beds and Lower to Upper Permian Back Creek Group. A Permian to Mesozoic diorite intrudes the western portion of the ATP.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION -Only one ATP (654M, Bligh Management Pty Ltd in 1970-71) has previously covered a portion of the current ATP area. Several stream sediment samples were collected by Bligh within this area and assayed for Cu, Pb, Zn and Mo. No anomalies were determined.

Exploration on previous ATP's 1444M, 1446M (Layton Associates, 1975), 1445M (Dear, 1980) held by L.H. Corser, and 2063M (Dear, 1980) held by the Marlborough Mining Syndicate, failed to delineate potentially economic mineralisation.

GEOLOGICAL MAPPING -Consultants N.F. Stuart and Associates were engaged to undertake a photogeological interpretation of the ATP in collaboration with Samantha technical personnel who provided ground control. 1:25 000 scale air photos were used as a base.

Petrographic work was performed by Dr S Joyce of Brisbane and details are presented as Appendix A.

GEOCHEMISTRY

- stream sediment sampling -A total of 255 samples were collected at an average density of 2 samples per square kilometre. A further 44 closely- spaced samples were collected to confirm and more accurately define the sources of a number of anomalies determined during the regional survey. Samples were assayed for Cu, Pb, Zn, As, Mo, and Sb. Results were statistically evaluated and threshold values determined for Cu, Pb, Zn and As.

Follow-up detailed sampling and field observations in most cases did not confirm, or failed to locate the cause of metal anomalies.

- heavy mineral sampling - A number of heavy mineral samples were collected by panning coarse stream sediment obtained from heavy mineral traps as close as possible to stream bedrock in areas shown to be geochemically anomalous in certain elements from the regional stream sediment survey. Each sample was examined microscopically for direct and indirect evidence of mineralisation. No free gold, evidence of hydrothermal activity, or diagnostic suites of minerals were noted.

- rock chip sampling -A number of rock chip samples were assayed in an attempt to determine the causes of the stream sediment anomalies. No definite indications of mineralisation were observed in the field, but samples were selected from Fe-stained material where present, otherwise random samples of country rock were taken in the vicinity of anomalous samples. Many of the anomalies were interpreted as a reflection of high background values in country rocks.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -Work during the term of the ATP consisted of a literature review, airphoto interpretation, regional geological mapping, stream sediment geochemistry, heavy mineral sampling and rock geochemistry. Several areas defined by groups of low order stream sediment anomalies in either Cu, Pb, Zn or As were investigated but no anomalies were determined to be significant. It was concluded from the results of the exploration programme that the potential for the occurrence of mineralisation was low and the ATP was subsequently relinquished.

SUMMARY:

GEOLOGY -

REGIONAL -The two predominant units in the area are the Upper Carboniferous Rockhampton Group comprising shallow marine sediments including mudstone, siltstone, feldspathic and lithic arenite, conglomerate, oolitic limestone and arenite, and the Lower Permian Berserker beds, a terrestrial and marine felsic volcanic sequence with minor sediments. The ATP lies along the fault-bounded western margin of the Berserker beds.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION -Esso Exploration held the area of interest under ATP 1075M in 1973. At this time a multi-technique airborne geophysical survey was flown involving E.M. (Barringer Mark V, 6-channel INPUT system), magnetics (Geometrics G803 nuclear precession magnetometer), and radiometrics (Exploranium DGRS 1000 differential spectrometer). Of the numerous INPUT anomalies defined, ten were chosen for follow up by either frequency domain IP or stream sediment geochemistry. No INPUT anomalies proceeded to the detailed gridding or drilling stage, nor were any of the stream sediment anomalies followed up.

GEOCHEMISTRY

- stream sediment sampling - 37 minus 80 mesh stream sediment samples were collected within the area of the ATP. All samples were assayed for Cu, Pb, Zn, Fe, Mn and As plus either Ni or Ag. Apart from an isolated Ni response indicating the underlying ultramafic rocks, no significant results were produced by this sampling programme.

- soil sampling - 429 reconnaissance soil samples were collected from five traverses at a sample spacing of 20 m. The traverses were laid out to cover the area of Esso Explorations large INPUT EM anomaly at Etna Creek. All samples were analysed for Cu, Pb, Zn, As, Ni, and Cr using AAS. Apart from elevated Ni and/or Cr values reflecting underlying ultramafic rocks, and elevated Zn values over subcropping basalts and andesites, no significant geochemical anomalies were found.

GEOPHYSICS

- ground surveys -

TEM Surveys A total of 40 x 200 m TEM loops have been read over the ATP. Contoured results are presented in plan form. This initial 200 m loop survey substantiated the previous INPUT EM anomaly and subsequently 77 overlapping 100 m loop TEM readings were taken over the main 200 m loop anomaly using a SIROTEM instrument. Stacked profiles are presented in plan form.

This survey defined very broad TEM anomalies which were interpreted as being due either to (a) a thin conductive sheet at a depth of around 50 m, or (b) conductive overburden of up to 200 m thickness. Additional time delay analysis on Line 7225N indicated that the response in this area was more probably due to conductive overburden.

IP Surveys In an attempt to resolve the conflicting TEM interpretations, two lines of 100 m dipole-dipole IP were read over the TEM responses on Lines 7175N and 4525N. Field sheets and pseudo sections are presented as Appendix 4 and 5 respectively.

The survey resulted in anomalously low resistivities of about 4-7 Ohm metres compared with background values of around 15-20 Ohm metres. However, there was no associated frequency percent anomalies. This IP response indicated a thick, gently west-dipping conductor, but the lack of a frequency effect response suggested that it was probably not due to sulphides but rather due to either a conductive overburden or a lithological change.

Ground magnetics A total of 6.95 km of ground magnetics have been recorded over the areas of TEM response. Field sheets and stacked profiles are included as Appendix 6 and 7 respectively.

LOCALISED EXPLORATION/PROSPECTS

GEOCHEMISTRY -Rock chip sampling was performed over the conductive zone identified in the previous six-monthly period. Ten samples were collected and assayed for Cu, Pb, Zn, As, Au, Ag, Ni, Cr. Some samples were also analysed for Fe, Mn, Sn, Sb, Hg, Mo, Ba and Bi.

DRILLING -Seven percussion holes were drilled on two drill traverses spaced 2650 m apart.

The initial phase of the drilling programme was designed to test for massive sulphide mineralisation near the eastern contact of the large conductive zone where a weak I.P. response and volcanic stratigraphy is present. Six holes were drilled for a total of 318 m (53 m each). This drilling intersected an essentially unmineralised sequence of felsic to intermediate volcanics, argillites and mafic to ultramafic volcanics and intrusives. Weak disseminated pyrite was present predominantly in the argillites.

A single, follow-up hole was subsequently drilled to a depth of 104 m in an attempt to conclusively define the source of the strongly anomalous conductivity. This hole intersected three different mafic lithologies, each of which contain magnetite, titanomagnetite and/or ilmenite and montmorillonite alteration after olivine. These lithologies comprise an upper dolerite with partially martitized magnetite, a thick middle zone of amygdaloidal, flow-lineated ex-olivine basalt with partially oxidised titanomagnetite and ilmenite, and a lower amygdaloidal dolerite with fresh titanaugite, calcic plagioclase, titanomagnetite and ilmenite.

All holes were sampled at 2 m spacing and analysed for Cu, Pb, Zn, As, Ag, Ni, Cr, and Au. Some samples were also assayed for Mo, Fe and/or Mn.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -A percussion drilling programme designed to test the source of an electromagnetic anomaly resulted in seven holes being drilled for a total of 422 m. The source of the anomaly was believed to be magnetite present in mafic lithologies intersected at shallow depth (< 100 m).

After testing the electromagnetic anomaly defined during the first six-monthly period it was decided that no further potential for volcanogenic massive sulphide mineralisation existed and the ATP was subsequently relinquished.

SUMMARY:

REGIONAL EXPLORATION

PREVIOUS EXPLORATION -In 1965 BHP Co. Ltd and International Nickel Ltd explored for lateritic nickel within ATP 294M which covered parts of ATP 3440M. Some stream sediment sampling was carried out in the current ATP area, however most was conducted further east.

Austral-Pacific Mining Corp. Pty Ltd and Mt Coora Mining N.L. assessed ATP 904M the chromite potential of serpentinites to the north on the current ATP.

ATP 1007M covering Mt Cassidy and its surrounds was granted to International Nickel Australia Ltd in 1971 to explore for base metals. Reconnaissance geological mapping and stream sediment geochemistry assaying for Cu, Pb and Zn outlined two areas of interest. Follow-up detailed geological mapping, rock chip and soil geochemistry showed that base metal anomalies were related to high background values in country rock.

The western portion of ATP 1362M held by ESSO in 1974 extended into the northern part of ATP 3440M. Base metal skarn deposits were the exploration targets. An aeromagnetic survey followed by ground magnetics and an IP survey failed to locate sulphide mineralisation.

BP Australia searched ATP 2510M for oil shale.

Peabody Australia Pty Ltd searched ATP 2817M for volcanogenic gold-copper mineralisation of Mount Morgan type. Stream sediment and soil geochemical copper anomalies in the vicinity of the Mount Cassidy mines were of particular interest. Soil and rock chip samples were collected across the anomalous copper zone to test for possible associated gold mineralisation. It was concluded that the gold mineralisation is unrelated to the anomalous copper values.

Reid (1931) visited and reported on the Mount Cassidy workings.

GEOLOGICAL MAPPING -N.F. Stuart and Associates were engaged to undertake a geological airphoto interpretation of the entire ATP area. Field control was provided by the consultants and Samantha staff. The report entitled "Authority to Prospect 3440M, Photo-interpretation and reconnaissance geology" is included in this company report as Appendix 1.

GEOCHEMISTRY

- stream sediment sampling -Approximately 500 samples were collected during a regional program at an average sample density of 2 samples per km2. Threshold values were determined for Cu, Pb and Zn and several samples were found to be anomalous. Field examination of each of these areas showed no obvious geological features of interest. Detailed stream sediment sampling was undertaken to confirm and more accurately define the sources of the anomalies. In no case was it possible to repeat or to determine the cause of the original high Au values. It was concluded that at least a large proportion of the original assays were in error.

Pan concentrate samples were also collected from trap sites. Each sample was examined microscopically for direct evidence of mineralisation. No evidence of hydrothermal activity or diagnostic suites of minerals was noted. No free gold was observed except in samples collected from the Mount Cassidy area.

- rock chip sampling -Apart from elevated Cu values on a small gossanous outcrop in Area A, rock chip results were poor.

- soil sampling -Samples were collected along ridges and spurs to test the drainage basins of streams indicated as being anomalous from the original work. No significant results were returned.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -As a result of the geochemical surveys conducted, the potential of the ATP is downgraded and no further work is recommended.

SUMMARY:

REGIONAL EXPLORATION

PREVIOUS EXPLORATION -The area covered by EPM 3470 was initially held by Central Oil Shale Pty Ltd under ATP's 1946M, 2196M and 2295M during the late 1970's. These authorities were joint ventured with Peabody Australia Pty Ltd and Beloba Pty Ltd (now jointly owned by Southern Pacific Petroleum N.L. and Central Pacific Minerals N.L.) in 1979. The authorities were conditionally surrendered in 1980 and two new authorities (2672M and 2673M) were granted for two years. In 1982 these two ATP's were conditionally surrendered in favour of a single ATP (3470M) covering the areas of interest. ATP 3470M was granted for five years from 5 May 1983. This authority was renewed for a further five years from 5 May 1988. The present Joint Venture was established in December 1988 when Central Oil Shale disposed of its' equity and The Shell Company of Australia purchased an equity. ATP 3470M became EPM 3470 on 1 September 1990 in line with the introduction of the new Mineral Resources Act.

GEOLOGY -The Rossmoya basin, which underlies the central-western part of the Hedlow Creek Plain, is as elongate north-west trending basin, 15 km long and up to 4 km wide. Rotary drilling (reported later) has shown that most of the plain surrounding the basin is underlain by basalt which forms basement to the Tertiary sequence. The basalts are laterally continuous with outcropping basalts at the south-eastern end of the plain which basalts are closely associated with a series of Late Cretaceous plugs of riebeckite trachyte in the Mount Hedlow area.

The Yaamba and Rossmoya basins and the associated Late Cretaceous basalts are separated by an uplifted block of Devonian Etna beds and Early Permian Berserker beds intruded by serpentinites, small stocks of diorite, andesite and feldspar porphyry. A series of limestone lenses in acid and intermediate volcanics of the Etna beds in the Mount Yaamba area represents a north-west extension of the Devonian limestone belt in the Mount Etna area.

The Hedlow Creek Plain is flanked to the northeast by sedimentary rocks of the Upper Palaeozoic Doonside and Wandilla Formations.

The Tertiary sediments intersected in the cored holes have consisted of pale grey and pale greenish grey mudstone, sandy mudstone, medium and fine grained lithic quartz sandstone and interbedded carbonaceous sequences of black lignitic oil shale, and carbonaceous mudstone. No thick or high grade oil shale section was located by drilling in the Rossmoya basin.

GEOCHEMISTRY -A small geochemical survey was carried out to complement work carried out in the 1960's by BHP. Thirteen stream sediment samples were taken from the main drainages emanating from Mt Yaamba. Thirty nine soil samples were collected from along a bulldozed fenceline which cuts across the top of the main peak. Samples were analysed for Hg, Cu, Pb, Zn, Ag, Au, As, Mn, Co and Ni. Essentially, all samples revealed only background levels.

GEOPHYSICS -A gravity survey carried out over the Rossmoya basin in 1982 indicated a gravity low with an anomaly amplitude of probably no greater than 50 um sec-2 and thus a probable maximum depth of 200 to 300 m. Drilling has confirmed that the depth of the basin is of that order..

DRILLING -The approximate extent of the Rossmoya Basin was defined by the drilling of 37 rotary holes over the Hedlow Creek Plain during the first phase of regional exploration carried out under ATP's 1946M and 2295M. Twenty one of these holes were drilled in the relinquished area, the subject of this report. Twelve of the holes intersected basalt immediately beneath the Quaternary alluvials. The other nine holes intersected Tertiary sediments, two of which penetrated to an 'andesite' basement. Logs of all 21 holes are provided in Appendix 1 of CR 24922.

Two cored stratigraphic holes (CPR400 and CPR401) were drilled in the basin in 1981, both penetrating to basalt basement. This drilling indicated a Tertiary sedimentary sequence of about 160 m with only minor oil shale in the lower part of the sequence. Another cored hole (CPR404) drilled in 1982 again penetrated to basalt basement and indicated a slightly thinner Tertiary sedimentary section of about 130 m. However this hole revealed a much better development of carbonaceous oil shale and lignitic oil shale. Lithological and graphic logs of these holes are presented in the company report. Another hole (CPR405) was drilled in 1991 to determine if there was further improvement in the oil shale section in the southeastern part of the basin. This hole was terminated at 210.5 m before reaching basement, when no worthwhile sections of oil shale had been encountered. A further hole was drilled in the north of the relinquished area in 1991 during geological reconnaissance of an adjoining EPM.

SUMMARY:

REGIONAL EXPLORATION

PREVIOUS EXPLORATION -BHP explored ATP 532M for base metals, principally copper. Eight areas were investigated in detail but no economic mineralisation was discovered. None of the eight detailed areas were located within ATP 3544M.

Mineral Deposits Ltd explored for base and precious metals using stream sediment sampling and IP geophysical surveys within ATP 1585M. One combined percussion/diamond hole was drilled. Investigations were centred on the northern edge of the Stanwell Valley where an anomalous copper zone was interpreted as being associated with the contact of the Native Cat Andesite and sediments of the Stanwell Valley. No economic mineralisation was found.

MINING HISTORY - At the time of writing of CR 12990, small scale alluvial gold mining was being carried out by J.W. Richardson near the Native Cat Prospect. A summary of production figures and geological notes on previous mines within the tenement is presented below.

Stanwell Goldfield

Native Cat Mine - Produced 6.2 kg Au from 270 t of ore at 23 g/t. Gold occurs in a pyritic quartz reef. Country rock is the Native Cat Andesite consisting of andesitic flows, tuffs and minor trachyandesite (Lower Permian Rookwood Volcanics).

Westwood Gold Mine - Located 16 km WSW of Mount Morgan. Produced 4 kg of gold from 230 t of ore at 17.4 g/t. Mineralisation occurs within a few feet of the underwall of a dolerite dyke where it intrudes slates. Gold is associated with quartz and arsenopyrite. Country rocks are possibly Lower Permian Youlambie Conglomerate.

Ridgelands Goldfield

Gold in this area is probably related to the Lower Permian Ridgelands Granodiorite, as is the gold in the Canoona and Morinish Goldfields.

Morning Star Mine - Locality stated in this report as "unknown". Produced 0.3 kg of gold from 8 t of ore. Small quartz reef 0.5 m wide assaying 50 g/t.

Rosewood Goldfield

Gold from this area is probably related to the Lower Permian Ridgelands Granodiorite. Several nuggets up to 100 ozs were found by alluvial mining. Little information is available on reefs.

Caledonia Reef - Location unknown. Quartz with pyrite and chalcopyrite.

Great Northern Copper Mine - Location unknown. Quartz reef with chalcopyrite and copper oxides.

MINING LEASES - Two mining leases are held within the tenement area. MLA 1047 "Golden Horseshoe" (Parish Morinish, Livingstone) granted for a period of ten years from 1/4/82. MLA 1079 "Morinish Ore" (Parish Morinish, Livingstone) applied for on 29/3/83.

GEOCHEMISTRY

Stream sediment sampling - 61 samples were sampled during the reporting period. At each site, a 5 kg bulk gold sample and a ferruginous gravel sample was collected.

Rock chip sampling -Six rock chip samples were collected during general reconnaissance of the tenement.

LOCALISED EXPLORATION/PROSPECTS

NATIVE CAT MINE AREA

GEOLOGY - Quartz-sericite-pyrite alteration is abundant at, and hydrothermal breccias occur at the Native Cat Prospect. Four grab samples of altered andesite taken at random from small dumps near the prospect returned values ranging from 14 to 118 ppm Au.

A total of 427 dip and strike measurements of joint planes were taken in the grid area. Rose diagrams were plotted and highlighted three principal joint sets.

11 rocks were collected in the Native Cat grid for petrological investigation. Two main rock-types are present - andesite and quartz-trachyte.

GEOCHEMISTRY - 9 stream sediment samples and four rock chip samples were collected and assayed during the first six-monthly period to 24 January 1984.

The old Native Cat Mine was gridded and soil samples collected at 50 m spacing. Composite rock chip samples were collected from trenches excavated in the Native Cat Mine area (see "trenching" below). Five dump samples were collected from old spoil heaps on the gridded area. 17 composite channel samples were collected from two trenches which had been excavated near the present alluvial workings at the head of Golden Spur Creek.

TRENCHING - 11 trenches were excavated in the Native Cat Mine area. Trenches ranged from 10 to 120 m with an average depth of 2 m. A total of 108 composite rock chip samples were collected from 9 of the 11 trenches. Samples were mainly 1 m composite channel samples taken along the base of one wall of each trench sampled.

MINERALISATION -Soil and rock chip sampling have outlined a zone of Au, Cu, Pb, Zn and Co anomalism centred around old workings over an area of 450 x 150 m. A lode zone consisting of microfractured, silicified and altered andesite was intersected in three trenches, TA, TC and TJ. The highest results were obtained in trench A where consecutive 1 m composite trench wall samples averaged 6 m of 7.1 g/t Au or 4 m of 10.3 g/t Au. The true width of the mineralised zone is uncertain but rock chip samples taken from similar lode material taken from old dumps adjacent to small pits returned assay results ranging from trace to 112 ppm.

The mineralisation is considered to be of hydrothermal origin, derived from the intrusive diorite and localised in fracture zones in the andesite. The shear zones are possibly related to movement along the margins of the intrusive diorite or associated with extensional stresses along the Stanwell Fault.

DRILLING -A total of 13 reverse circulation percussion holes were drilled on the Native Cat Grid. The drillholes were selectively sampled for geochemical analysis. Minor base metal and gold anomalies were recorded with the highest values in drillhole NCRC-13, where an average of 2.48 ppm gold was recorded in altered andesite between 6 and 13 m.

Supergene enrichment in poddy haematitic shear zones in the Native Cat Andesite is considered to account for the majority of the anomalous gold and base metal values returned from the drilling program.

Primary hydrothermal-style mineralisation was intersected in drillhole NCRC-1 at 26 m (0.4 m of pyritic quartz) and is similar to dump material located near NCRC-3, presumably derived from an adjacent major shaft which is still standing to 15 m. The shallow, highly oxidised (supergene) mineralisation intersected in NCRC-13 is of limited extent and follows a line of old workings for about 70 m.

ROSEWOOD AREA

Six stream sediment samples were collected and assayed.

GOLDEN SPUR

Five rock chip samples were collected and assayed. One rock from the Golden Spur area was also submitted for petrological examination.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE - It was concluded that the Native Cat grid area showed little economic potential and the tenement was surrendered and the joint venture terminated.

TRANSFERS, JOINT VENTURES, etc: LEASES TAKEN OUT: COMPANY REPORT Nos: Open File-12900, 13895 Confidential- SUMMARY:

GEOLOGY -

LOCAL Sedimentary rocks in the area mapped have steep dips (60-75o) to east. The oldest sediments are acid tuffs and tuffaceous sandstones and greywackes and are seen in contact with the intrusive Bouldercombe Complex and have been metamorphosed by the intrusives. These sediments may be equivalents of the upper units of the Pond Formation of lower Carboniferous age. These are overlain by a limestone unit (50 m maximum thickness) probably marking the beginning of the Neils Creek clastics. The basal limestone is skarnised in the vicinity of the Hidden Star and garnet, epidote and hornblende occur in more pelitic units. This unit contains the Hidden Star mineralisation.

This unit is overlain by a thick sequence of spotted silty phyllites, shales and fine greywackes (450 m maximum thickness). The silty phyllites are spotted by carbonate growths due to contact metamorphic effects and are ferruginous between Hidden Star and Gavial Creek where they exhibit IP effects.

A very thick (approx. 700 m) sequence of interbedded black cherty mudstones and arenaceous greywackes with minor quartzites overlies the phyllites. Individual units vary in thickness but average 5-10 m. A sequence of black cherty mudstones and siltstones overlies the interbedded sequence before passing abruptly into a thick (550 m) sequence of fine to coarse-grained greywackes up to conglomerate size. The top of this sequence is not seen in the area mapped.

Bouldercombe Complex - The Upper Permian Bouldercombe Complex is represented in the area by poorly outcropping granodiorite, hornblende gabbro, dolerite and aplitic phases. Aeromagnetics indicate a strongly magnetic body in contact with the sediments in the area mapped and this is probably represented by the granodiorite phase. Minor hornblende gabbro occurs near the intersection of the Burnett Highway and Midgee-Gracemere Road with closely associated finer grained phases. Aplitic rocks occur near the Burnett Highway and are seen cutting the granodiorite in the vicinity of Hector Reef. Contact metamorphic effects related to the Bouldercombe Complex appear up to 1 km from the surface contact of the intrusives.

Structure - Sediments in the area generally strike NNW and possess steep (60-75o) easterly dips indicating little deformation. Considerable faulting interpreted in a radial pattern about the intrusive mass causing offsets up to 100 m of marker units. This is related to the relatively passive intrusion of the Bouldercombe Complex.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION - Gold was mined at two locations within the ATP - Hector Reef (1890- 1913, 27.5 kg Au from 6335 t of ore) and Hidden Star (1934-1937, 50.9 kg Au from 3314 t of ore). Production was from quartz reefs within granodiorite in the case of Hector, and within altered slates and skarnised limestones at or near the granodiorite contact in the case of Hidden Star.

The area has been covered in part by ten previous ATP's, however only three of these entailed any work in the area of ATP 3546M.

Consolidated Zinc carried out soil sampling over an area west of the Burnett Highway in the search for copper mineralisation. The Hector Reef area showed a zone of broad but low tenor copper anomalism, considered not worthy of follow-up.

Mines Exploration Pty Ltd (MEPL) performed IP profiling over the granodiorite contact after anomalous results were discovered during broad spaced reconnaissance style IP traversing in the search for "porphyry copper" style targets. A zone of "low-order, real anomalies" was found in sediments, near and parallel to the contact. One diamond drillhole was drilled south of the Hidden Star area, and intersected hornfelses, mica schists, andesites and trachytes with some evidence of skarn. Disseminated pyrite, pyrrhotite, marcasite and trace chalcopyrite were observed as "macroscopically abundant over a few inches in several places".

BHP explored for copper, nickel, platinum group metals,and uranium mineralisation under ATP 532M. Aeromagnetics were flown which showed up the Kabra magnetite skarn deposit. An aeromagnetic high at Midgee was drilled and intersected barren gabbro. No specific ground work was conducted in the area of ATP 3545M.

GEOLOGICAL MAPPING -Regional geological mapping was conducted using 1:10 000 scale photo- enlargements of 1:30 000 scale air-photos. Mapping was conducted along traverses spaced at 500m.

LOCALISED EXPLORATION/PROSPECTS

Old diggings have been found in five different areas within the area mapped, however only 3 areas show evidence of mineralisation.

Mystery Reef - A shaft 10 m deep was dug on vertical quartz reef (trending 304 MN) averaging 10-20 cm wide, cutting through sedimentary rocks containing thin limestone lenses, and diorite and aplite intrusions. At the end of a drive 20 cm of reef grades 39.8 g Au, 4 g Ag.

Hidden Star (Gleaming Star) - Gold occurs in "bedded replacement veins" up to 1.5 m wide but averaging less than 1 m. The "reefs" comprise vitreous or porcelanous quartz with biotite, garnet and chlorite.

The deposit was worked via 4 shafts to 19 m maximum depth. Table 1 of this report lists grades as quoted in Denmead (1935).

Geophysics - A geophysical consultant G.O. Dickson reviewed data produced by BHP and MEPL in the Hidden Star area. Points of note include

1. The magnetic response is disturbed in the Hidden Star area and probably represents faulting.

2. The granite contact appears to dip west.

3. The granite body is interpreted as a late stage episode, radial fractures are related to the centre of intrusive activity further west.

4. A resistivity contact parallels the magnetic contact but is displaced eastwards.

5. There is some chance of a massive conductor on line 175N.

6. There is some chance of a narrow conductive zone along strike between lines 175N and 205N.

7. MEPL drillhole DA-1 did intersect the IP responsive zone.

Geochemistry -An auger soil sampling programme was conducted in two parts. The Hidden Star trend was sampled at 2 m spacings with 50 m traverse spacings. A more regional survey with a sampling interval of 25 m on 100 m traverse separations to encompass the immediate extent of old workings. Assay results, calculated background and threshold values are presented in this report in table form as well as plots.

The auger soil geochemical copper assays broadly follow the granodiorite outcrops. Within this geochemical cupriferous zone zinc-arsenic values show a more specific but as yet unconfirmed trend, that may be coincident with old workings.

No geochemical pattern has specifically identified the Hidden Star workings. At this stage, separate arsenic and copper geochemical trends suggest more of a lithological control which also hosts the known gold mineralisation in this area.

Geology -A geological map at 1:5 000 scale was produced coincident with the area of the soil surveys.

SUMMARY:Auger geochemical sampling of the prospective trends within the "Hidden Star" ATP commenced during this period, but has yet to be completed. The most prospective areas have been sampled.

Results to date show a variable lithological response by separate elements, consistent with the known regional geology.

Old workings in the granodiorite horizons appear to lie within a more specific zinc-arsenic trend with a broader ill-defined copper halo. The geochemical-lithological coincident within the sediments shows a different response which has yet to be shown as indicative of the known gold mineralisation in the area.

A landsat interpretation and data compilation of Mines Department Open File reports were completed over the area covered by ATP 3630M.

Geological investigations and rock chip sampling were completed over a portion of the New Zealand Gully workings. Gold mineralisation at New Zealand Gully in general appears to be restricted to narrow quartz lodes and shears cutting through acid/intermediate tuffs and agglomerates of the Berserker beds. The maximum lode thickness was 1.5 m observed at Olsen's Gold Prospect, however most were considerably narrower.

Despite the occurrence of minor quartz veining within the country rocks adjacent to the auriferous lodes, no gold mineralisation was found to occur outside these auriferous lodes.

At the Keppel Bay View Prospect mineralisation consists of significant widths of essentially sulphide- silica rock. Patches of what appear to be strongly silicified tuffs indicate this to be a replacement body. A stockwork of quartz veins occurs within country rock adjacent to the sulphide-silica lenses.

The best assay result was 41.7 ppm Ag at Keppel Bay View Prospect. Widespread kaolinistaion of the host volcanic rocks as observed in surface exposures appears to be a function of weathering and not true alteration.

LOCALISED EXPLORATION/PROSPECTS - Detailed geological mapping at 1: 1000 scale was conducted over the Hunter 4-5 area (MLA 1078). A grid was bulldozed and surveyed. Orientation soil sampling program was completed. An IP survey was conducted over the area.

GEOLOGY -The Hunter 4 alteration zone represents the core of an anticline or partial domal structure in rocks equivalent to the Mt Chalmers mine hanging-wall rocks. Abundant old gold workings occur in these rocks in shears, minor quartz veins, and altered rocks. Anomalous gold and base metal values are indicated over a wide area of the exposed altered horizon, as indicated by previous Geopeko results and a recent soil sampling traverse done by Newmont.

The Hunter 5 area, south of Hunter 4, includes alteration zones in acid and andesitic rocks, some of which may represent lateral equivalents of the Hunter 4 alteration zone. Major workings also occur in quartz veins, shear zones and quartz-feldspar porphyry intrusives.

GEOCHEMISTRY -Soil sampling in the Hunter 4 & Hunter 5 alteration zones yielded significant anomalies.

135 rock-chip samples of outcrop and mine dump material were taken from the Hunter 4 area and 30 samples from the North Star area at Hunter 5. Gold values to 1.184 ppm and silver to 6.0 ppm as well as anomalous copper, lead and zinc define a geochemical anomaly centred at 9800N, 9950E in the Hunter 4 area corresponding to the area where old workings are most numerous.

Of the 30 samples from the North Star area of workings, 9 returned gold values greater than 3 ppm up to 24.8 ppm and up to 20.5 ppm Ag. 8 of these samples were quartz vein material and one was an altered tuff.

GEOPHYSICS -A gradient array survey conducted over the Hunter 4-5 grid defined an anomaly in the area 9400N to 9800N and 10 500E to 10 300E. A dipole-dipole survey covering this anomaly was carried out to define drill targets.

DRILLING -Three percussion holes totalling 342 m were drilled on the Hunter 4 area to test the resistivity and chargeability anomalies defined by the IP survey. Samples were collected at two metre intervals and submitted for assay by AAS.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -Anomalous, but economically insignificant gold, silver, copper, lead and zinc concentrations are widespread throughout the pyritic ash tuff unit at Hunter 4. The drill holes testing the IP anomaly intersected pyrite in concentrations higher than seen elsewhere, however assay results are similar and probably reflect high background values at the same stratigraphic position as the Mt Chalmers mineralisation. No other significant IP anomalies remain to be tested in the survey area.

Further work in the Hunter 5 area could be undertaken to evaluate the significance of the high gold and silver values from the North Star and the gold, silver. arsenic and barium values from the small bedded gossan at 9430N, 10640E. Because of the negative results of drilling in the Hunter 4 area, no further work is recommended.

EXPLORATION TARGETS\MODELS:Gold and VMS base metals.

SUMMARY:

GEOLOGY -

LOCAL -The geology of the ATP area is described as consisting of.. "Silurian-Permian, basic-acidic, extrusive-chemical-argillaceous sequences intruded by basic to ultrabasic rocks and the Permian Ridgelands Granodiorite. In several areas pyrometasomatism has developed magnetite-garnet-epidote skarns." The geology of the major mines and prospects within the ATP is also described.

REGIONAL EXPLORATION

PRODUCTION HISTORY - Recorded production for the Morinish Gold Field totals 10 377 t yielding 303 kg Au at 29 g/t. The largest producers were the Welcome Reef which yielded 81.7 kg, the Alliance Mine (84.6 kg and the Mt Morinish Mine (32.4 kg). The Morinish Gold Field was mined predominantly during the period 1890 to 1909.

PREVIOUS EXPLORATION -A detailed literature review encompasses state archive material, wardens reports from Annual Reports Department of Mines, Queensland Government Mining Journal and more contemporary company reports.

GEOCHEMISTRY

- rock chip sampling - Rock grab sampling was conducted during reconnaissance fieldwork. All samples were submitted for assay. Some rock samples were also submitted for petrological analysis.

FINAL COMMENTS - It was concluded that (1) the ATP area had potential to host volcanogenic and pyrometasomatic base and precious metal mineralisation. Of particular interest was the RG 42 anomaly where gossanous ironstone of possible syngenetic origin assayed 2.61g/t gold. (2) past exploration had not exhausted the potential of the tenement area. (3) the Blackfellows Gully gold prospects are simple quartz fissure reef deposits which would not support a viable company size mining venture. (4) anomalous gold values (Mineral Deposits Ltd) at the Esso B siliceous zone are attributed to a Cretaceous-Tertiary deep lead. (5) there is a highly speculative potential that the gold mineralisation at the Hector-Alliance mines may be associated with a volcanogenic system rather than a simple quartz fissure vein.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -To test the potential of the outcropping Connors Volcanics for gold mineralisation similar to that occurring in the Connors Volcanics in the Broadsound Range to the northwest in ATP 3234M.

GEOLOGY -

LOCAL -Results of geological mapping indicated that the Connors Volcanics outcropping within the ATP comprise a thick sequence of andesitic volcanics which are lithologically identical to the Macksford Volcanics exposed in the Broadsound Range to the northwest. The andesitic volcanics in the main trend approximately N-S and dip east.

Copper mineralisation is present as malachite staining in vesicles and quartz veins, as well as disseminated specks . A similar style of copper mineralisation occurs in andesites in the lower part of the Macksford Volcanics in ATP 3234M, but occurs several hundred metres stratigraphically above the highest occurrences of gold mineralisation.

Regional mapping indicated correlations between the Connors Volcanics in the two areas but indicated that the sequence outcropping in ATP 3854M was too high within the Connors Volcanics to contain equivalents of the prospective acid volcanic sequences represented in ATP 3234M.

Limited rock chip sampling in the area confirmed copper mineralisation but failed to locate any significant gold grades.

MINERALISATION/ALTERATION -No indication of significant zones of hydrothermal alteration or sequences of pyritised volcanics were found.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE - Geological mapping indicates that the thick andesitic sequence represented within the Connors Volcanics in the authority area can be correlated with the Macksford Volcanics which crop out toward the top of the Connors Volcanics in ATP 3234M, and is therefore too high in the Connors Volcanics section for the occurrence of the favourable stratigraphy containing gold mineralisation present in the latter area.

LOCALISED EXPLORATION/PROSPECTS Gold panning was undertaken initially to determine areas of higher gold concentrations. Follow-up sampling involved collecting 6 kg samples from pit excavations to a depth of 1.75 m from the main creek bed and alluvial banks along the western side of the creek (total of 16 pits; locations are shown on a map in the report). Samples were washed in a dish, visual estimations made, and gold averages were calculated for each pit (range from nil up to 0.67 g/t).

SUMMARY:

GEOLOGY -

REGIONAL - The ATP's include the northern portion of a northwest trending belt of ultramafic rocks which extend some 30 km from Rockhampton to Marlborough. These ultrabasics are thought to have intruded the Palaeozoic metamorphics in the Middle Devonian and block faulted to their present position during the Upper Permian.

The western part of the area is dominated by Palaeozoic mica schists (north trending foliation) near Marlborough Creek.

LOCAL - The ultramafic rocks are predominantly serpentinite (dominant mineral is antigorite) formed by the metamorphism of original dunite, harzburgite or Lherzolite. Near the contacts it is schistose, but elsewhere it is generally massive with a mottled appearance due to ghosting of the original pyroxene. Faulted contacts with adjacent units are common. Small granodiorite bodies intrude the serpentinite in the north of the ATP area.

MINERALISATION/ALTERATION - Within the area sub-economic deposits of nickel/cobalt, chromite, chrysoprase, magnesite, and gold have been reported.

Chromite is predominantly associated with serpentinite and peridotitic serpentinite. It occurs mainly as lenses and bands. At some locations (Flying Fox, Racecourse, and Mt Redcliffe), the serpentinite bodies are tectonically disrupted and cut by faults. Six major occurrences occur in the area, these include Big Boy, Racecourse, Flying Fox, Fraser's Workings, Mt Redcliffe, and Nine Mile Creek. Macroscopically, the ores can be subdivided into three types: 1) Massive ore consists of >70% by volume of coarse grained chromite with little interstitial serpentine. 2) Disseminated ore contains mostly xenomorphic chromite crystals <1 mm in diameter, in a matrix of serpentine. 3) Leopard ore is formed by orientated spindle shaped chromite aggregates with internal cumulus texture and massive chromite rims within a serpentine matrix.

This phase of exploration has concentrated on the occurrence of podiform chromite deposits within the ultramafics. Approximately 30 occurrences of refractory chromite were delineated in the area. These range from restricted areas of chromite float or sub-crop to the Princhester disseminated chromite deposit (approx 40 000 t of 28% Cr2O3)

Magnesite occurs mainly in the northern part of the area.

REGIONAL EXPLORATION The exploration program concentrated on the location of all the primary chromite occurrences within the ATP area.

PREVIOUS EXPLORATION - BHP and International Nickel (INAL) carried out extensive exploration in the 1960's for Ni-Co mineralisation under ATP 294M. Four large areas of ultrabasics were defined, the largest is situated south of Marlborough (560 sq km), another in the Canoona area (240 sq km). Four deposits of lateritic nickel with minor cobalt mineralisation were defined: Brolga (10.76 Mt), Canoona (3.65 Mt), Coorumburra (4.02 Mt), and South Slopeaway ((5.06 Mt). The deposits were considered to be uneconomic and were covered by Departmental Area 130D.

Limited evaluation of the chromite potential was carried out in the Princhester area, and limited chrome assays were reported from the Brolga, Canoona, and Mt Slopeway prospects. It appears that the presence of refractory grade chromite deterred further exploration.

Numerous mining leases have been held in the vicinity of the chromite occurrences. During the nickel boom of the late 1970's, Meekatharra Minerals held much of the ground over the ultrabasics and laterite outcrop south of Marlborough. Significant production from underground workings at Delandelles (Racecourse) is apparent. Recorded production of disseminated chromite ore for the period 1962-1965 from the general region totalled 600 t.

Vein magnesite had been mined in the area, the most important mine was Frasers Workings, 10.5 kms south-southeast of Marlborough. In 1985 the very large Kunwarara Magnesite deposit was defined.

Gold has been won from alluvial and hard rock mines in the Canoona area, and traces of gold have been reported from the serpentinite south of Marlborough Homestead.

Chrysoprase deposits have been mined from the laterites developed on the serpentinites south of Marlborough Homestead.

GEOLOGICAL MAPPING - 1:25 000 scale mapping was undertaken.

GEOCHEMISTRY - Extensive sampling of the chromite lodes and float was undertaken to determine the grade of the deposits. Microprobe analyses of selected samples was carried out to determine the chemical composition of the chrome spinel.

LOCALISED EXPLORATION/PROSPECTS

CHROMITE

The following prospects were examined:

Racecourse Prospect (MLA 1105) Princhester BS 6 Prospect Eastern Hill Western Hill Nine Mile Creek area - Rockabilly, Lucky Strike, Johns No 2, Mongrel Creek, Top of the Hill Spring Creek area - Blue Camp Hills, Emu Lode, Spring Creek West Flying Fox area - Flying Fox East, Flying Fox East No 2 Marlborough Mine Area - Bill 4, High Lode, Emu Lode, Kay's No 1, Stony Creek, Big Boy Fraser's Prospect

Drilling and costeaning was carried out at several of the prospects with very little success.

Chromite mining proved unfeasible due to the additional cost of benefaction, the small size of the local market, and the high cost of shipping of small orders to overseas markets.

MAGNESITE

The most significant occurrences of magnesite was found to be in the area east and west of Fraser's mining lease (ML 1104). The magnesite occurs as veins or irregular shaped bodies (ranging from few cm to >1 m) within the serpentinite bodies. Most of the work in the area included trenching and sampling. The most favourable areas were defined as: Location 17, Location 30, and West of Fraser's. Other areas examined include:

The magnesite deposit was thought to have significant potential, however, as it was not possible to attract a joint venture partner, the deposit had to be abandoned.

GOLD

Areas explored include: Princhester area Spring Creek Gold values were disappointing with the best result of 0.44 ppm. No further work was proposed for the area.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -

GEOLOGY -

The western part of the area is dominated by Palaeozoic mica schists (north trending foliation) near Marlborough Creek.

LOCALISED EXPLORATION/PROSPECTS

GEOLOGY - As a result of geological mapping in the area, several rock types were identified within the ultramafic complex. Serpentinite is dominant with subordinate peridotitic serpentinite, minor dunite, as well as irregular shaped lenses or dykes of gabbro and small anorthosite bodies. Generally the serpentinites are dense and range from light to dark grey-green. In the south and west parts of the area they are laterised, red and strongly weathered.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -

Regional Mapping located over 30 occurrences of refractory grade chromite in the ATP's. These occurrences range from restricted areas of chromite float or sub-crop to the Princhester disseminated deposit (approx 40 000t of 28% Cr2O3).

GEOLOGY -

REGIONAL - Exploration concentrated on ultramafic units which are widespread in the region.

LOCAL -

MINERALISATION/ALTERATION - Mineralisation in the area was characterised by structurally complex pods of chromite which were difficult to delineate with the drilling programs outlined below.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION -

GEOLOGICAL MAPPING -

LOCALISED EXPLORATION/PROSPECTS

FLYING FOX

GEOLOGY - Chromite pods were found in the quarry face of the Flying Fox Prospect and in small outcrops on the old track to the summit of the hill in the southwest corner of ATP 4149.

DRILLING -

Seven percussion holes were drilled around the old workings of this prospect.

The first two were drilled to test the assumption that the chromite was in a flat lying sheet dipping to the north. These holes were unsuccessful and it was assumed that a north-south fault must have cut the chromite body off between the exposures and the drill hole.

The third hole was drilled to the east to intersect the fault postulated from holes 1 and 2 and, hopefully, to intersect the chromite ore body but the hole was unsuccessful.

The fourth hole was drilled vertically to see if the sheet (interpreted in holes 1 and 2) was beneath the platform. This hole was also unsuccessful.

Hole number 5 and 6 were drilled at the outcrop in the northern face and one intersection was found in hole 6.

Hole 7 was drilled to see if the intersection in hole 6 could be extended to the east but this hole also failed.

The drilling at Flying Fox was completely unsuccessful but further excavation is planned to better define the complex structural nature of the structural features controlling the chromite pods.

FRASERS

GEOLOGY - The Frasers Prospect on ATP 4150M was mainly defined on the basis of dense chromite float in the creek and on the nearby hillsides. However drilling and costeans placed in the area did not reveal any chromite body.

COSTEANS - A delay in arrival of drilling equipment was used to dig costeans on the prospect. Approximately 110m of north-south trenches were dug which failed to show any bedrock chromite although a zone of magnesite up to 15m wide was discovered.

DRILLING - A total of 213 R.A.B drill holes were sunk to test for chromite. All of these holes were unsuccessful.

RACECOURSE

GEOLOGY - Racecourse prospect (MLA 1105) was mined by earlier tenement holders and approximately 2000 tonnes of chromite were removed. Chromite was encountered in three out of 117 holes supporting the companies interpretation of the ore as being structurally complex and having a poddy nature. The pods appeared to be en echelon to a structural trend of approximately 0650 despite the fact that individual pods trended slightly east of north.

REDCLIFFE

GEOLOGY - Old workings on the flanks of Mt Redcliffe in ATP 4150M were examined by excavation and drilling. Chromite is exposed along a fault plane which forms a 5m high cliff on one side of the workings. The drillholes intersected a number of substantial occurrences of chromite but all of these occurrences were characterised by low Al2O3 chromite and, therefore, was not attractive.

BIG BOY

GEOCHEMISTRY - The outcrop of chromite ore at Big Boy is approximately 9m long, 3m high, and 2m wide. Assays of samples from this outcrop were high in SiO2 (up to 8.27%) considering the good appearance of the chromite in hand specimen. Further excavation revealed a better grade low silica core surrounded by disseminated or "leopard ore"material.

SPRING CREEK

GEOCHEMISTRY - Six trenches were dug at Vic's Find on Spring Creek to investigate small outcrops of chromite in an area of heavy float. No assays were available at the time the report was written.

PRINCHESTER

GEOLOGY - The largest of the occurrences on the two ATPs were mapped and revealed that most of the occurrences at the Princhester prospect were high silica porphyry or "leopard" chromite which was not considered to be of interest to the company holding the lease.

EXPLORATION TARGETS\MODELS: Refractory grade chromite; magnesite; gold

SUMMARY:

LOCALISED EXPLORATION/PROSPECTS CHROMITE Racecourse Prospect (MLA 1105) - Further pitting was undertaken to better define the three larger pods already outlined. Tonnage and grade available for development was determined and a conceptual pit plan was developed. However, the ore below the immediately surface zone is 1% to 3% higher in silica rendering it unmarketable in this form. This ore may possibly be improved by benefaction and tests are proposed.

Princhester - This deposit was previously mapped and drilled by Australian Industrial Refractories Ltd (BHP) from 1976 - 1978 who determined a probable ore reserve of about 86 000 tonnes of disseminated chromite. Boulder Gold carried out trenching to determine whether significant pods of massive chromite were present within the disseminated material. The results of the work were inconclusive.

BS 6 Prospect - 800 tonnes of eluvial chromite bearing material was gathered for washing and sorting at the upgraded plant. Trenches were excavated to determine whether hard rock lode material occurs beneath the eluvial ore.

Eastern Hill - consists of massive serpentinite with NW trending veins and layers of chromite (crystals 1- 5 mm in serpentinite matrix) passing through the top of the hill. Magnesite veins are also present.

Western Hill - The ore occurs in serpentinite masses, a large percentage of which consists of disseminated and 'leopard ore'. A series of trenches (568 m) were excavated to determine the amount of massive chromite in the deposit. Results to date were inconclusive.

The viability of a refractory grade chromite operation in the area was investigated by assessing the base line production costs. In addition, chromite samples were sent to Balfour McLaine Metals in New York for distribution to various possible consumers.

MAGNESITE The most significant occurrences of magnesite was found to be in the area east and west of Fraser's mining lease (ML 1104). The magnesite occurs as veins or irregular shaped bodies (ranging from few cm to >1 m) within the serpentinite bodies. Most of the work in the area included trenching and sampling. The most favourable areas were defined as: Location 17, Location 30, and West of Fraser's.

GOLD Princhester area - Nine trenches were excavated (241 m) and sampled (46) in an area which included old workings. The gold proved to be related to quartz veins (2-10 cm) in brecciated mafic intrusive rocks. Au assay results were disappointing, the best value was 2.38 g/t, but most ranged from 0.01 g/t to 0.04 g/t.

Spring Creek - The rocks in the area consist of mica schist, quartzite, quartz, and quartz rich ironstone. Eight old gold diggings were located and samples were collected and analysed. Results were dominantly low, ranging from 0.04 g/t to one sample at 11 g/t. Follow-up work was proposed for this area

Other areas were also examined. Additional work included 1:25 000 mapping, pitting, trenching, sampling, and assaying. New colour photography over selected areas was flown for the Joint venture??

SUMMARY:

LOCALISED EXPLORATION/PROSPECTS CHROMITE - Further reconnaissance exploration was carried out to determine the chromite potential of the area. Areas were inspected, sampled, and samples analysed. Additional deposits were delineated (listed below) and air-photos were flown over selected areas for follow-up mapping.

Nine Mile Creek - This is the most promising area in terms of abundance and quality of chromite. The ore varies from dense monomineralic chromite to medium to coarsely crystalline disseminated material. The deposits defined in this area include: Rockabilly - This deposit consists of a layer of chromite which pinches and swells (1 m - 4 m thick) over a distance of about 100 m. The ore appears massive in the centre and disseminated towards the margins. Large floats of ore are abundant over the area. Lucky Strike - This deposit is located north of Rockabilly, on the opposite slope. The ore, which is 70% massive and 30% very fine grained disseminated, was traced 20 m - 30 m up the slope, and along the slope for about 30 m. Johns No 2 - It is located 600 m north of Lucky Strike on the same hill range. The ore, which outcrops over an area of 50 m by 20 m, consists of chromite outcrop, scree occurrences, and large boulders, on top of a hill. The chromite outcrops consist of layers or lenses with an average thickness of one metre. The quality of the ore is very good. Mongrel Creek - It is located west of Mongrel Creek on the upper part of a hill where the ore consists of disseminated chromite over an area of about 50 m by 50m. The quality of the ore is medium and would require some benefaction. Top of the Hill - The deposit outcrops on the top of the hill of 'Lucky Strike' over an area of 2 m by 4m. The immediate area (area of about 50 m by 50 m) is covered with large boulders of chromite and other small outcrops. The ore is 90% massive and 10% disseminated.

Spring Creek Area - Three promising looking chromite deposits were found in this area, however, mining of Blue Camp Hills and Emu Lode could be a problem due to the steep topography. Blue Camp Hills - The outcrop, which extends some 50 m, is located close to the top of a steep hill 2 km NE of the chromite sorting plant. It occurs as a layer? about 2 m thick at the western end, and 1.5 m at the eastern end. The ore is 30% massive and 70% disseminated. The area is covered by a thick scree of chromite. Emu Lode - The deposit occurs on the slope of a steep hill, some 1250 m NNE of Moessingers Mine. The outcrop is 7 m long by 3 m wide at its widest point. The ore is predominantly massive (approx 10% disseminated) chromite. Spring Creek West - It is located north of Prospect 5 on the slope of a small hill. The outcrop is a layer of coarsely disseminated, good quality chromite, 5 m long by 2 m wide. The slope is covered by a dense scree of chromite.

Flying Fox Area - The area east of ML Flying Fox includes a number of chromite occurrences. These consist mainly of disseminated chromite which would require some benefaction. The two most significant deposits are: Flying Fox East - This deposit occurs as a chromite outcrop (7 m by 7 m) located on a spur about 900 m east of Flying Fox. The ore is disseminated with grains to 2 mm common. Flying Fox East 2 - The deposit is located in a valley 1km east of Flying Fox. It occur as a layer, about 4 m long by 3 m wide with smaller associated lenses, in an outcrop of about 9 m by 5 m. The ore is disseminated.

Other Chromite Lodes - Spot samples from other localities were collected and analysed as part of the regional evaluation process.

The grade of the ore (high, medium, or low Al2O3) was thought to be stratigraphically controlled, however, as all individual occurrences were located in shear zones, they were also subjected to structural controls. Chemical specification of the ore and ore treatment proposals were also presented. FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -

SUMMARY:

LOCALISED EXPLORATION/PROSPECTS CHROMITE - No chromite exploration work was undertaken during this period. The work concentrated on: - testing of ore for grade and product suitability - ore benefaction tests - test assay result variability - examine export methods - rehabilitation of previously trenched areas

MAGNESITE - No magnesite exploration work was undertaken during this period. Markets for natural magnesite as distinct from dead burned material were investigated.

GOLD Spring Creek Area - As a result of mapping, sampling, and assay results, a favourable area of about 150 m by 75 m was defined in rocks consisting of silicified limonitic schist with occasional zones of brecciation. Follow-up trenching revealed that the ore was restricted to a very narrow, probably fault related zone, where quartz infilled zones of brecciation and silicification coincided with sulphide introduction. Gold values were disappointing with the best result of 0.44 ppm. No further work was planned for the area.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE - Although a great deal of data and information on chromite has been compiled for the area, a number of geological and economic factors combined to mitigate against the development of the resource: - The small size and scattered nature of the occurrences, together with the variable grade of the ore, make the deposits uneconomical to mine. - The larger deposits contain the less desirable 'leopard' ore, ie marble size chromite concentrates encased in the serpentinite host rock. - Market requirements are specific and require stringent specifications, particularly with regard to silica content. Ore would have to be blended and/or benefacted.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -To explore for magnesite and gold.

GEOLOGY -

REGIONAL -The metamorphic rocks within the prospect area may be a metamorphosed equivalent of the Curtis Island Group.

LOCAL -The existing Britannia mine shaft and smaller workings are confined within a northerly dipping sequence of fine-grained grey dolomitic and carbonaceous siltstones interbedded with medium-grained lithic-vitric-tuffs of the Permian Berserker beds. Rocks within the immediate vicinity of the main shaft and smaller workings are marked by intensive hydrothermal alteration and randomly oriented pyritic quartz-carbonate veining frequently oxidised to a spongy limonite. Material in the mine dumps is mainly of this type. Siltstones further away from the alteration zone lack the intense quartz-carbonate veining but nevertheless contain abundant fine-grained disseminated pyrite.

MINERALISATION/ALTERATION -An oval-shaped zone of intense hydrothermal alteration and quartz veining, measuring 140 x 100 m is centred on the Britannia Mine.

QMC inferred (1) that the original hydrothermal fluids may have been focused along the permeable faulted argillite/serpentinite contact and then into faulted or fractured zones within the argillites and (2) that some gold may have precipitated in the contact zone in response to the chemically reactive nature of the serpentinites. Mineralised wall rocks rather than veins may be the dominant style of mineralisation within the fault zone (see figure 4)./

REGIONAL EXPLORATION

PREVIOUS EXPLORATION -The occurrence of magnesite in the area has been known about for a long time, with references generally confined to occurrences of magnesite in veins within weathered ultramafic rocks. Reports on magnesite occurrences within the Marlborough area include Ridgeway (1941), Brooks (1964) and Cuttler (1958).

The most comprehensive evaluation of magnesite deposits in the Marlborough region was undertaken during 1981 and 1982 by Kaiser Aluminium and Chemical Corporation under ATP;s 2778M, 3003M and 3004M. Although Kaiser noted the occurrence of nodular magnesite in the area its evaluation was never pursued (Kaiser Refractories 1982a & 1982b).

Working on behalf of Cudgen RZ Ltd and its subsidiary Industrial Minerals Pty Ltd, Union Corporation (Australia) Pty Ltd reported on work undertaken on ML 444 in 1978 (Union Corporation 1979). Union Corporation recognised the sedimentary nature of the magnesite occurrence 5 km SSW of Marlborough. A Cudgen subsidiary (Omya Pty Ltd) has subsequently extracted small quantities of material for the fertiliser market. The only mine working consists of a single cut in a creek bank on ML 444 where a 2.5 m thick seam of good quality nodular magnesite has been exposed beneath 1 m of black soil cover.

During 1985 Queensland Metals Corporation expanded the known reserves of magnesite around ML 444 within ATP 4009M before announcing the discovery of the very large (> 550 x 106 tonnes) Kunwarara magnesite deposit.

ATP 4209M contains the Canoona Goldfield which was discovered in 1857 and represented the first discovery of payable gold in Queensland. The field was largely an alluvial producer with 40 000 oz of gold produced prior to 1860.

Only two hardrock gold occurrences have been documented in ATP 4209M.

Keiths Hill - 2 km south of Canoona, a total of 2.3 kg gold slugs were recovered from fissures in serpentinite (Reid 1931).

Britannia Mine - 1 km north of Mona Vale homestead 14.2 kg of gold was extracted from 862 tonnes of ore. Dunstan (1913) reported that the ore came from a quartz reef in diorite.

Modern exploration of the Canoona Goldfield was carried out by the following companies:

1964 - BHP explored for Cu, Ni and Cr in the serpentinites under ATP's 242M and 294M. Little attention was paid to the gold and precious metal potential of the Palaeozoic sequence.

1974 - Esso Australia Ltd conducted base metal exploration under ATP 1362M for replacement and contact pyrometasomatic deposits around the edges of the Ridgelands Granodiorite without success.

1982 - Electrolytic Zinc Company of Australia Ltd explored the Britannia Mine area under ATP 2608M for stratiform base metal and low-grade disseminated precious metal mineralisation in the Berserker beds. The exploration target was presumably a volcanogenic model based on the Mount Chalmers deposit. The exploration programme conducted by EZ consisted of : * Geological mapping at 1: 31 680 scale. * Stream sediment sampling of the entire ATP for Cu, Pb, Zn, As, Ag and Ni. 456 samples were collected at a sample density of 4 per sq km over the Berserker beds and 2 per sq km over metamorphic and intrusive rocks. * Auger soil sampling at the Britannia Mine.

EZ identified seven anomalous zones (A-G) but only Zone A, which covers the Britannia Mine, is presently considered. The main conclusions drawn by EZ were - Gold and silver mineralisation is confined to narrow quartz carbonate veins in shear zones transecting the sediments at high angles. - Chip sampling and soil sampling eliminated the possibility of extensive stratabound or disseminated base metal/precious metal mineralisation in felsic volcaniclastics. - Arsenic is the most useful pathfinder element for gold.

LOCALISED EXPLORATION/PROSPECTS

GEOLOGY & GEOCHEMISTRY -A program of 1: 10 000 scale alluvial mapping and stream sediment sampling was conducted on Bonnie Doon and Canoona Creeks. It was found that Canoona Creek contains very little gravel and that the alluvium is dominated by silt and soil. It was concluded that Canoona and Bonnie Doon Creeks had no potential for alluvial gold.

During the course of mapping, several areas of extensive diggings in shallow colluvial serpentinite wash were located in the headwaters of Bonnie Doon Creek. The larger of these covers an area approximately 700 x 60 m.

A total of 165 trap samples were collected at nominal spacings of 500 m. Each sample comprised approximately 9 kg of -5 mm material which represented 20-40 kg of unseived alluvium. Trap samples were concentrated to about 200 g and then panned to assess the size and number of gold particles. Visible gold was present in 27 samples and up to 8 particles were found in a single sample. The majority of gold was extremely fine with no grains coarser than fly speck size. Pan concentrate samples were analysed for Au, Ag, Cr and W. Au and Cr values ranged up to 40 ppm and 10.5% respectively but Ag and W were within normal background levels.

Where silt was available, a -80 mesh sample of active alluvium was collected. Silt samples were analysed for Au, Cu, Pb, Zn, Ag, Co, Cr, As, Ba, Hg and Mo. Gold was anomalous in a few samples up to a peak of 150 ppb, and Co and Cr ranged up to 250 ppm and 6100 ppm respectively.

The high levels of Co and Cr are attributed to the nearby serpentinite.

DRILLING

A 5 hole (476 m) percussion drilling program was conducted on the Britannia lode. All holes were angled at approximately 60o. No significant mineralisation was encountered. The drilling revealed that carbonaceous shales which crop out poorly in the grid area are in fact relatively common in the subsurface. Disseminated pyrite is practically ubiquitous in all lithologies. Cuttings samples from the more promising intersections were submitted for assay but results were not at hand at the time of reporting.

Limited drilling conducted in the north-east sector of EPM 4209 revealed that the EPM has little potential for an economic magnesite deposit.

SUMMARY:

REGIONAL EXPLORATION

PREVIOUS EXPLORATION -A review of available information was conducted at the Dept. of Mines library. Useful information on old workings in the area were gleaned from the three local Rockhampton newspapers, namely The Rockhampton Bulletin, The Northern Argus, and The Capricornian, together with Department of Mines records. Interviews were conducted with former miners, and farmers who are the descendants of miners. Information from interviews has been transcribed, and is available upon request from Crusader Oil (the parent company of Saracen). This material has been compiled both chronologically and by individual mineral occurrence. A total of 1406 references to individual occurrences has been extracted from this data.

The ATP was overflown by both helicopter and fixed-wing aircraft. All observed diggings were photographed in colour and form part of the archive on the area.

MINERALISATION - Nine distinct types of gold deposit have been identified and examined within the ATP as listed below.

1. Structure-controlled lineations within a granite pluton - Ridgelands.

2. Gold on the contacts between a granodiorite pluton and metamorphosed hornfelses.

3. Gold in linear tension features on the margins of a granodiorite pluton in a chloritic quartzite - Rosewood

4. Gold in quartz veins in an outer ring of mineralisation surrounding a granodiorite intrusion - Rosewood.

5. Gold in shale - Slaughteryard Gully, at Rosewood.

6. Gold in quartz veins within volcanogenic extrusives and sediments - Morinish and Blackfellows Gully.

7. Gold in interbedded conglomerates - Hunters Gully and McMasters Gully at Morinish.

8. Eluvial gold derived from weathering of all of the above - all areas

9. Alluvial gold transported by streams from the above - Rosewood, Morinish and Blackfellows Gully.

LOCALISED EXPLORATION/PROSPECTS

RIDGELANDS GOLDFIELD- Two sets of soil samples were collected from a grid established over the main diggings at Ridgelands. The mean value for the first set of samples is 184 ppb. The mean of the second set is 86.8 ppb.

8 samples, each of approximately 2/3 of a tonne, were taken from previously assayed sites on the Ridgelands Grid. These samples were washed through the mobile plant for minimal returns.

During the period ended 20/8/1988 27 rock chip samples were collected and analysed. The layered gabbro samples had consistently low gold values (<0.02 - 0.03 g/t). Similarly hornfels from the country rock/intrusive contact had values of 0.02 - 0.06 g/t Au. Quartz vein samples had a greater range in values <0.02 - 14.60 g/t, although only five samples had significant values 3.39-14.60 g/t.

In addition to gold analyses, three samples of gabbro and one sample of granodiorite were analysed for Cr, Pt and Pd with no significant results.

MORINISH GOLDFIELD

Geology -The rocks at the old Mt Morinish and Alliance Mines are predominantly made up of intermediate to basic volcanics and volcanogenic sediments. The typical splintery fracture and generally indistinct hornfels-like texture suggests silicification induced by the emplacement of the Ridgelands Granodiorite. This is further evidenced by (1) the occurrence of a banded 'spotted' lithology about 150-200 m west of the Mt Morinish mine and also 250 m north of the Alliance mine. (2) an outcrop of garnet skarn 250 m north of the Alliance mine and (3) the occurrence in the same area of radiating sillimanite crystals within a hornfels host rock. In both the Mt Morinish and Alliance areas, the ridgetops are characterised by a distinctive, poorly sorted conglomerate.

The structure of the reefs can only be evaluated from the occurrence of old mine shafts and adits. At the Alliance Mine the line of collapsed adits strikes approximately 020 degrees. At the northern end of the line, about 150 m in a WNW direction, a large shaft is found suggesting that the reef does dip to the west, consistent with state archives which report the reef struck 010 and dipped 45o west. At Mt Morinish the trend of the old mine workings is similar to that of the Alliance Mine although the whole area appears to have been offset about 200 m in a WNW direction.

Geochemical exploration- 90 rock samples were collected from mullock heaps around the Welcome mine (GR 101247 Ridgelands). The samples were dollied and crushed on site and despatched for assay for gold only. The western group of mullock heaps shows a range of average values from 117 ppb to 1616 ppb.

Test dredging was carried out using a two inch intake portable Keene suction dredge, at six mine sites on the Welcome Flats, three on the lower reaches of Hunters Gully, two in the gully west of, and draining the Welcome Mine area, two sites on Louisa Creek, and three sites in the vicinity of sparse diggings at GR 107258 Ridgelands. Five minute runs were done at each site, and all produced fine colours except Hunters Gully which was barren. Results are presented on page 31 of this report.

30 soil samples were taken from holes dug by pick and shovel at ten metre intervals, along a line traversing the shallow diggings centred on GR 087255 Ridgelands. The original name for these diggings is unknown but they have been labelled the Grasshole Diggings in this report. Most assays were below detection limit.

Four alluvial test pits were dug by hydraulic excavator, and one costean by bulldozer at Morinish.

During the period 21/8/1987 to 20/2/1988 (CR 18718) rock chip sampling was conducted in the McMasters Gully, Alliance, English Bee, Golden Rose and Last Chance areas. Gold mineralisation in these areas is present in quartz veins in metamorphosed sediments and volcanics. Sixteen samples were collected, of which eleven gave results of above 1 ppm.

In the northwestern portion of the Morinish Goldfield, twelve rock chip samples were collected from the Blackfellows Gully - Homeward Bound Connors Relief and Sleeping King areas. Five samples (all from mine dumps) gave results greater than 1 ppm (CR 18718).

During the period ended 20/8/1988 (CR 18795), 25 rock chip samples from this area were analysed. At Mt Morinish, quartz vein material collected from mullock heaps ranged from 0.02 - 8.40 g/t Au with 5 of the 8 samples being greater than 1.2 g/t Au. Country rock samples had gold values greater than 3 g/t with a maximum of 37.20 g/t Au. North of the Alliance mine, the range in values was 0.02 - 48.00 g/t. Ten rock chip samples were collected from the Sleeping King area. Values ranged from 0.06 to 18.50 g/t.

Drilling

Two diamond drillholes were placed to the north of the old Alliance Mine in a bid to intercept the gold-bearing veins beyond the reported workings. The main rock type encountered was a light to dark grey, slightly siliceous metasediment with bands of poorly sorted conglomerate up to 3 m thick. Drillhole MMA/2 intercepted a gold- bearing (21.8 g/t) quartz vein at 32 m which is possibly related to the original Mt Morinish/Alliance lode.

Blackfellows Gully

Geology -The majority of mullock heaps comprise volcanic/volcanogenic rocks typically showing feldspar phenocrysts with a groundmass of variable texture and composition. Fine-grained, dark grey mudstones were found in some piles but were not as widespread as the volcanics. Minor granitic material was found in some piles. Quartz veins appear to be located within the fractured volcanic host rocks. The veins (and fractures) strike NW-SE and dip to the SW (CR 18795).

Geochemical exploration -A mullock heap sampling program was conducted over the Blackfellows Gully Mines, Morinish No. 2 Goldfield. These mines worked 1 to 12" quartz reefs in a medium to dark grey, microcrystalline volcanic rock.

51 tractor-mounted auger drillholes were sunk and soil samples collected and analysed.

A five tonne bulk sample of alluvial wash was collected from a gully draining the Homeward Bound group of mines, and treated in a mobile plant. The net grade recovered was 3 g/t.

Six Mile Creek was tested using a 2" Keene dredge at five sites between GR 019346 and GR 017341 (Ridgelands). Between 2 and 10 fine colours were obtained at these sites in five minute runs. No coarse gold was recovered. Lack of water in the creek prevented testing with the 5" dredge.

During the period ended 20/8/1988, 74 rock chip samples were analysed and returned gold values ranging from 0.02 - 37.80 g/t (CR 18795).

Welcome Flats - Two excavator pits, and the bulldozer costean were sited in the Welcome Flats alluvial diggings area. Gold won from these apparently washed down from the Welcome Hills area which includes the Welcome Mine. Most of the old pits were apparently relatively shallow, but a single deep shaft is known to have reached well-rounded boulders at 80'. 20 t of material from each pit was trucked to Rosewood and washed in the alluvial plant there. Very little gold was recovered. Logs of the pits, and assay values reported from the test plant are presented on pages 35 - 37.

The brick clay potential of the area was also evaluated. A 30 t sample of clay was collected.

McMasters Gully - These old diggings are centred on GR 095265 Ridgelands, and extend over 250 m on the north flank of German Hill and on the southern side of what is now termed McMasters Gully. The diggings appear to be very shallow (1 -1.3 m). The first test pit dug by the excavator unearthed timbered drives in an interbedded conglomerate of unknown age, at 15'. It would therefore appear that the diggers were working a deep lead as the conglomerate is overlain by a shaly bed.

A second test pit dug at the western end of the McMasters Gully workings tested the report of Mr Frankish and Mr Richards that a shaft at the site sunk by Mr Frankish's grandfather (Charles Frankish) had worked a conglomerate at 80'. The shaft, its ladder and a tin bucket were excavated with work stopping at 8 m (the excavators depth limit). The mullock shows that the wash they worked was a partially cemented, well-rounded pebble conglomerate. A five tonne sample yielded only a trace of gold. This shaft and pit suggest that either the main conglomerate dips to the west or that a second deeper auriferous conglomerate exists at the site. Dips measured on the overlying shale suggest the latter.

It is reported in CR 18795 that mineralised volcanics were found only on top of the hill to the western side of the area. Minor sulphides occur within a fine-grained, splintery rock.

All non-alluvial workings at McMasters Gully are associated with a dolerite dyke. CR 19997 reports that four trenches were dug at right angles to the strike of the dolerite dyke. All of the trenches extended through the dyke into country rocks on either side. The difference between the two rock types was clearly visible, with the darker brown dolerite contrasting sharply with the surrounding light grey metasediments. The contact between the two rock types was frequently characterised by a narrow zone (up to 60 cms) of highly altered and fractured calcareous material. Channel samples were taken along the entire length of each trench at 1-2 m intervals depending upon the presence or not of visible quartz veins. The highest gold value recorded was 12.70 g/t in trench 4 (48 m long; strike 071o). From preliminary field investigations, a relationship between the vein quartz and free gold had been established. The quartz veins were found exclusively in the dyke rock and did not extend into the surrounding country rocks which were devoid of gold. The visible quartz veins were invariably flat lying with a shallow dip to the NE up to 2.5 cm wide. The quartz found in the trenches was mostly gossanous with iron oxides visible along fractures and within vughs, however, boxwork structures were not observed.

Diamond drilling - Three diamond drillholes were put down adjacent to the most prospective trenches. The holes ranged in depth from 35 to 55 m and had various inclinations (CR 19997).

A total of 19 samples were analysed, 4 from country rock and the remainder from or associated with the dolerite dyke. Dyke rock values ranged from 0.05 - 0.12 g/t Au and associated quartz vein material ranged from 0.02 - 15.00 g/t (CR 18795).

ROSEWOOD GOLDFIELD

Geology-The are of worked ground follows closely the contact between granitic rocks and hornfelsed country rocks. The most extensively worked over ground is 50-150 m N of Rosewood Creek, however pits can be found along the entire length of the observed contact, a distance of 750 m. The contact is irregular but generally trends NW-SE. The granite contains abundant xenoliths and enclaves of country rock (grey-green hornfels). The workings are found exclusively within the country rock and are associated with veins (possibly up to 30 cm wide) of a quartz-calcite assemblage with minor sulphides.

Geochemical exploration - A total of 605 soil samples were taken on the old Rosewood Goldfield. Here the gold and copper mineralisation is hosted by quartz veins in andesite and associated volcaniclastic rocks which have been hornfelsed by the nearby Rosewood Granite.

During the period 21/8/1987 to 20/2/1988 (CR 18718) rock chip samples were collected from the Caledonian and Golden Bar mines within the ATP, and the Rosewood Copper Mine and Lucky Hit to the west of the ATP boundary. Eleven samples were collected from within the ATP and six of these gave results of more than 0.5 ppm. All samples were collected from mine dumps.

During the period ended 20/8/1988 (CR 18795) rock chip sampling yielded the following results in the Caledonian and Golden Bar areas. Golden Bar - Gold values for 13 samples collected ranged from 0.02 to 7.08 g/t. Caledonian - 12 samples were analysed. Values ranged from 0.1 to 10.00 g/t.

GEOPHYSICAL EXPLORATION

During the period 21/8/1987 to 20/2/1988, several aeromagnetic anomalies outlined in ESSOs 1974 report were investigated and their causes are reported in CR 18718. Some geochemical exploration was conducted over a number of these anomalous zones.

ESSO's anomaly B - This anomaly corresponds with a small granitic intrusion in silicified and hornfelsed metasediments. Magnetite sand is common, and there are prospecting pits, showing secondary copper minerals in siliceous skarn on the southwest side.

Rock chip sampling was conducted over anomaly B with no significant gold results.

ESSO's anomaly D Mt Eagle - Rocks in this area comprise a sequence of variably hornfelsed and metamorphosed andesitic to dacitic volcanic rocks and volcanogenic sediments of dacitic composition. Within the volcanogenic sequence minor bands of cherty metasediment, probably a reconstituted mudstone occur. The rocks possess a NNE - SSW strike and dip moderately (15-35) to the east. 16 samples were analysed. Only 4 samples of quartz vein material, taken from the mullock heap of the only working in the area, had significant gold values (0.15 - 9.23 g/t) (CR 18795).

FINAL COMMENTS/REASON FOR RELINQUISHMENT

No fieldwork was performed during the six-month period ended 20/2/1990 (CR 21476). Results of previous exploration were reviewed and assessed indicating that only the region surrounding the Homeward Bound - Carnarvon Castle Mine areas warrants further investigation. It was recommended that the area surrounding the Homeward Bound and Sleeping King areas should be retained and should be investigated in detail.

CR 22170 reports that the mapping programme in the Blackfellows Gully area failed to locate any auriferous quartz veins other than those previously worked. It was deemed that this left little potential for an economic sized deposit within the ATP and it was recommended that the tenement be surrendered in full.

LOCALISED EXPLORATION/PROSPECTS

Blackfellows Gully - A mullock heap sampling program was conducted over the Blackfellows Gully Mines, Morinish No. 2 Goldfield. These mines worked 1 to 12" quartz reefs in a medium to dark grey, microcrystalline volcanic rock.

51 tractor-mounted auger drillholes were sunk and soil samples collected and analysed.

A five tonne bulk sample of alluvial wash was collected from a gully draining the Homeward Bound group of mines, and treated in a mobile plant. The net grade recovered was 3 g/t.

Ridgelands - Two sets of soil samples were collected from a grid established over the main diggings at Ridgelands. The mean value for the first set of samples is 184 ppb. The mean of the second set is 86.8 ppb.

8 samples, each of approximately 2/3 of a tonne, were taken from previously assayed sites on the Ridgelands Grid. These samples were washed through the mobile plant for minimal returns.

Morinish - 90 rock samples were collected from mullock heaps around the Welcome mine (GR 101247 Ridgelands). The samples were dollied and crushed on site and despatched for assay for gold only. The western group of mullock heaps shows a range of average values from 117 ppb to 1616 ppb.

Four alluvial test pits were dug by hydraulic excavator, and one costean by bulldozer at Morinish.

The brick clay potential of the area was also evaluated. A 30 t sample of clay was collected.

Rosewood - A total of 605 soil samples were taken on the old Rosewood Goldfield.

SUMMARY:During this reporting period, work consisted of examination and sampling of old goldfields and ESSOs (1974) aeromagnetic anomalies.

LOCALISED EXPLORATION/PROSPECTS

GEOCHEMISTRY -Rock chip samples were collected from the Ridgelands Morinish and Rosewood Goldfields.

In the Morinish Goldfield (McMasters Gully, Alliance, English Bee, Golden Rose, Last Chance) the gold mineralisation is present in quartz veins in metamorphosed sediments and volcanics. Sixteen samples were collected, of which eleven gave results of above 1 ppm Au. Some specimens contained visible gold.

MINING DISTRICT: MINES/PROSPECTS: EXPLORATION TARGETS\MODELS:Gold in the vicinity of the Ridgelands, Morinish, Blackfellow,s Gully and Rosewood goldfields.

SUMMARY:

GEOLOGY

LOCAL -Igneous rocks assigned to the Ridgelands Granodiorite in fact constitute a gabbroic rather than granitic intrusion. No outcrops of gabbro were observed but abundant large boulders with variable mineralogy show that the gabbro is differentiated and in places phase layering is clearly seen. One sample of granodiorite was found on the NW edge of the mapped area. The nature of the relationship between the gabbro and the granodiorite could not be established.

Country rocks where exposed consist of interbedded grey limestones and calcareous mudstones. Bedding thickness varies from a few mm up to 30 cm. The beds generally strike NW and dip to the NE.

LOCALISED EXPLORATION/PROSPECTS

GEOCHEMISTRY -Ridgelands Mining Field - 27 samples were collected and analysed. The layered gabbro samples had consistently low gold values (<0.02 - 0.03 g/t). Similarly hornfels from the country rock/intrusive contact had values of 0.02 - 0.06 g/t Au. Quartz vein samples had a greater range in values <0.02 - 14.60 g/t, although only five samples had significant values 3.39-14.60 g/t.

In addition to gold analyses, three samples of gabbro and one sample of granodiorite were analysed for Cr, Pt and Pd with no significant results.

ESSO's anomaly B - Rock chip sampling was conducted over ESSO's anomaly B with no significant gold results.

McMasters Gully - Mineralised volcanics were found only on top of the hill to the western side of the area. Minor sulphides occur within a fine-grained, splintery rock.

All non-alluvial workings at McMasters Gully are associated with a dolerite dyke.

16 samples were analysed. Only 4 samples of quartz vein material, taken from the mullock heap of the only working in the area, had significant gold values (0.15 - 9.23 g/t)

Mt Morinish - Alliance Mines - The rocks at the old Mt Morinish and Alliance Mines are predominantly made up of intermediate to basic volcanics and volcanogenic sediments. The typical splintery fracture and generally indistinct hornfels-like texture suggests silicification induced by the emplacement of the Ridgelands Granodiorite. This is further evidenced by (1) the occurrence of a banded 'spotted' lithology about 150-200 m west of the Mt Morinish mine and also 250 m north of the Alliance mine. (2) an outcrop of garnet skarn 250 m north of the Alliance mine and (3) the occurrence in the same area of radiating sillimanite crystals within a hornfels host rock. In both the Mt Morinish and Alliance areas, the ridgetops are characterised by a distinctive, poorly sorted conglomerate.

25 samples from this area were analysed. At Mt Morinish, quartz vein material collected from mullock heaps ranged from 0.02 - 8.40 g/t Au with 5 of the 8 samples being greater than 1.2 g/t Au. Country rock samples had gold values greater than 3 g/t with a maximum of 37.20 g/t Au. North of the Alliance mine, the range in values was 0.02 - 48.00 g/t.

Blackfellows Gully (Homeward Bound/Connors Relief) - The majority of mullock heaps comprise volcanic/volcanogenic rocks typically showing feldspar phenocrysts with a groundmass of variable texture and composition. Fine-grained, dark grey mudstones were found in some piles but were not as widespread as the volcanics. Minor granitic material was found in some piles. Quartz veins appear to be located within the fractured volcanic host rocks. The veins (and fractures) strike NW-SE and dip to the SW.

74 rock chip samples were analysed and returned gold values ranging from 0.02 - 37.80 g/t.

Sleeping King - The geology of the Sleeping King area comprises a succession of metamorphosed and hornfelsed interbedded tuffaceous sediments, feldspathic agglomerates, and occasional mudstone horizons. The major metamorphic effect appears to be moderate recrystallisation of the primary textures and variable chloritisation to produce a distinctive green appearance to the rock. Complete chloritisation is accompanied by pyrite mineralisation. The area which has been most extensively worked is strongly chloritised and suggests that the process of chloritisation and mineralisation are related. Samples collected from mullock heaps indicate that the mineralisation was associated with both quartz and calcite veins.

The volcanogenic/sedimentary sequence strikes NNE - SSW and dips 35-50o to the east. The alignment of workings does not coincide with the attitude of the host sequence and indicates that the mineralised quartz and calcite veins are not concordant with the regional structure.

10 rock chip samples were collected with values ranging from 0.06 to 18.50 g/t.

Golden Bar - Caledonian Mines, Rosewood - The are of worked ground follows closely the contact between granitic rocks and hornfelsed country rocks. The most extensively worked over ground is 50-150 m N of Rosewood Creek, however pits can be found along the entire length of the observed contact, a distance of 750 m. The contact is irregular but generally trends NW-SE. The granite contains abundant xenoliths and enclaves of country rock (grey-green hornfels). The workings are found exclusively within the country rock and are associated with veins (possibly up to 30 cm wide) of a quartz-calcite assemblage with minor sulphides.

Gold values - Golden Bar - Gold values for 13 samples collected ranged from 0.02 to 7.08 g/t.

Caledonian - 12 samples were analysed. Values ranged from 0.1 to 10.00 g/t.

SUMMARY:

LOCALISED EXPLORATION/PROSPECTS

McMasters Gully - Trenching - As reported earlier, all non-alluvial workings in the McMasters Gully area are associated with a dolerite dyke. Four trenches were dug at right angles to the strike of the dolerite dyke. All of the trenches extended through the dyke into country rocks on either side. The difference between the two rock types was clearly visible, with the darker brown dolerite contrasting sharply with the surrounding light grey metasediments. The contact between the two rock types was frequently characterised by a narrow zone (up to 60 cms) of highly altered and fractured calcareous material. Channel samples were taken along the entire length of each trench at 1-2 m intervals depending upon the presence or not of visible quartz veins. The highest gold value recorded was 12.70 g/t in trench 4 (48 m long; strike 071o). From preliminary field investigations, a relationship between the vein quartz and free gold had been established. The quartz veins were found exclusively in the dyke rock and did not extend into the surrounding country rocks which were devoid of gold. The visible quartz veins were invariably flat lying with a shallow dip to the NE up to 2.5 cm wide. The quartz found in the trenches was mostly gossanous with iron oxides visible along fractures and within vughs, however, boxwork structures were not observed.

Diamond drilling - Three diamond drillholes were put down adjacent to the most prospective trenches. The holes ranged in depth from 35 to 55 m and had various inclinations.

Mt Morinish - Alliance Mine - Two diamond drillholes were placed to the north of the old Alliance Mine in a bid to intercept the gold-bearing veins beyond the reported workings. The main rock type encountered was a light to dark grey, slightly siliceous metasediment with bands of poorly sorted conglomerate up to 3 m thick. Drillhole MMA/2 intercepted a gold-bearing (21.8 g/t) quartz vein at 32 m which is possibly related to the original Mt Morinish/Alliance lode.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -The Authority was acquired to explore for secondary magnesite mineralisation in the Cainozoic Jim Crow Basin

GEOLOGY -

REGIONAL -ATP 4474M straddles the northwestern contact between Palaeozoic carbonates and argillites of the Devonian/Carboniferous Curtis Island Group to the north, and inferred extensions of the Permian Cawarral Serpentinite Belt (concealed beneath Cretaceous basalt and Cainozoic alluvium) to the south.

Cainozoic cover over the southern portion of the ATP is believed to represent a southern extension of the Jim Crow Basin.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION -An office-based literature review was conducted .

GEOPHYSICS

Airborne surveys -Aeromagnetic data previously acquired by BHP was examined. Magnetic zones were identified which probably reflect greenstones of the Cawarral Serpentinite Belt beneath cover.

LOCALISED EXPLORATION/PROSPECTS

DRILLING -11 holes were drilled for a total of 192 m. Only minor traces of magnesite were observed in one hole over an interval of 1 m and at a depth of 14 m.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -Analytical results of basement rock samples showed no anomalous values of base metals or gold. Drilling has shown that the area is not underlain by an extension of the Cawarral Serpentinite Belt. The airborne magnetic features previously believed to represent the Cawarral Serpentinite Belt were more likely due to extensive Cretaceous basalt beneath Quaternary/Cainozoic cover.

The 1: 50 000 scale geological map covers the majority (northwestern part) of the Rockhampton 1: 100 000 Sheet area. No geological boundaries are presented for areas west of the Berserker Graben.

SUMMARY: GEOLOGY REGIONAL -A folded sequence of Siluro-Devonian to Permian volcanics and sediments dominates the ATP. Permian to Mesozoic granitoids intrude most lithologies. The area consists of two anticlines (the Craigilee Anticline to the east (and passes through Mt Cassidy itself) and another to the west. A syncline occupies the central portion of the ATP. All fold axes strike north-south. Siluro-Devonian spilitic volcanics are exposed in the core of the anticlines and are overlain by Carboniferous sediments. Permian sediments are exposed in the synclinal closure.

The Siluro-Devonian volcanics are the host to all known mineralisation on the ATP and are the preferred lithology in the nearby Morinish Goldfield. They consist of a sequence of trachytic felsic-intermediate tuffs and lavas, spherulitic rhyolites and possible intrusive porphyritic dacitic rocks. The volcanics appear to be largely subaerial although limestone beds high in the sequence suggest some marine incursion. Some previous explorers have drawn analogies between these rocks and the sequence at Mt Morgan.

The intrusive rocks are mostly grey granodiorite stocks that cause skarn/marble formation where in contact with limestone units in the Siluro-Devonian volcanics and overlying Carboniferous sediments.

PREVIOUS EXPLORATION

The area has been previously explored for both gold and base metals including:

INCO - 1972 - ATP 1007M - Stream sediment sampling around Mt Cassidy delineated Cu anomalous zone east of the old gold workings.

PEABODY - 1980/81 - ATP 2817M - Followed up the Cu anomaly found by INCO by conducting two rock/soil sample traverses, and sampled the pits on Mt Cassidy.

SAMANTHA - 1983/84 - ATP 3440M - Stream sediment, soil and rock chip sampling.

THOMDRILL - 1986/87 - ATP 4553M - 128 BCL samples, rock-chip follow up of anomalous zones.

Stream sediment sampling by Thomdrill has defined a 2 km2 gold anomalous zone within which lies the Mt Cassidy workings. The main area (with historic production) was reportedly a siliceous pyritic lode in porphyritic volcanics. 500 m west of these shafts, shallow pits in a saddle contain siliceous pyritic breccias. Samples from this zone (collected by Thomdrill) returned an average of 5.5 g/t (max. 25 g/t) with 12 of 23 samples > 1.0 g/t. Percussion drilling of the west Mt Cassidy area was completed in 1987 with disappointing results.

GEOCHEMISTRY

Stream sediment sampling -A stream sediment sampling programme, designed to infill coverage in an area south west of Mt Cassidy, where previous samples are consistently anomalous over a large area, was carries out in February 1988. Samples were also collected from areas not previously sampled. Samples were assayed using BCL method. Prospecting and rock chip sampling were carried out simultaneously.

Rock chip sampling -35 rock chip samples were collected during the stream sediment sampling programme particularly in areas previously defined as anomalous.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -There are several groups of minor workings on the slopes of Mt Cassidy and surrounding hills. Only the largest of these have recorded production; 435 Tonnes for 121 oz Au to the end of 1935.

Infill and follow-up sediment samples in the area south west of Mt Cassidy were generally disappointing and indicate that the source(s) of anomalous drainage are small and isolated. Sample density in this area is now 6 samples per square kilometre and further sampling is not justified. Two areas of highly Au anomalous drainage remain unexplained; 2 km west of Mt Cassidy where recent sampling produced a result of 18.2 ppb Au upstream from an initial anomaly of 6.7 ppb Au, and 1 km south of Mt Cassidy where several anomalous samples appear to coincide with a fault block of limestone. Geological prospecting in both areas failed to explain source of the anomaly, but ruled out the possibility of a major alteration/mineralisation system.

To date over 200 BCL samples and over 100 rock chip samples have been collected from the area and analysed. The majority of anomalies were from the Mt Cassidy and West Mt Cassidy workings. Ten (10) percussion holes (total 365 m) tested the near surface potential of the West Mt Cassidy area without success. Other areas of anomalous drainage have been prospected and it is concluded that the elevated gold values are due to sources of restricted size. Withdrawal from the joint venture was recommended.

A map at 1: 50 000 scale shows sample locations as well as geological observations and interpretive boundaries. This could be "plugged in" to a pre-field-season compilation map.

SUMMARY:

LOCALISED EXPLORATION/PROSPECTS

DRILLING -A 10 hole percussion drilling programme totalling 356 m was completed at West Mount Cassidy. Holes were designed to test an area of alteration, quartz veining and pyritic breccias 400 m SW of the Mount Cassidy Mine. Most holes intersected widespread zones of weak propylitic alteration and disseminated pyrite within a sequence of NE dipping andesitic lavas and tuffs below the mineralised structure. All but two (2) holes returned anomalous gold values (> 0.10 g/t). Only one (1) hole returned > 1.0 g/t.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -Drilling indicated that quartz veining and brecciation do not persist beneath surface outcrops and exposures in pits and shafts west of Mount Cassidy. Although both steeply dipping and flat lying quartz veins can be observed at the surface, it appears that the major structure in the drilled area dips shallowly to the northeast.

REASON FOR ACQUISITION OF TITLE -The authority was considered prospective for epithermal style gold mineralisation associated with Permo-Carboniferous igneous activity and major lineaments.

GEOLOGY -

REGIONAL -Lower Permian Camboon andesite and the associated Lower Permian sediments and volcanics of the Rannes beds occupy the central and southern parts of the authority. The northern part is underlain by the Lower Permian Rookwood Volcanics comprising mainly spilitic lavas. The Rookwood Volcanics are intruded by undated (Permian to Mesozoic) stocks which range in composition from granite to diorite/gabbro.

The rocks have been deformed and now form part of the Gogango Overfolded Zone.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION -Previous exploration for volcanogenic base metal mineralisation has been carried out in the Rookwood Volcanics in the northern part of ATP 4713M by Bligh Management Pty Ltd (under ATP 694 in 1969 - 1971) and Getty Oil (under ATP 2376M in 1980). Getty Oil followed up Cu,Pb, Zn mineralisation located by Bligh Management, a few kilometres east of Rookwood Homestead. The base metal mineralisation is associated with gossanous rhyolitic breccias which crosscut the Rookwood andesites along faults in shear zones. Outcrop is poor in the area of interest. The base metal mineralisation was uneconomic (1000-5000 ppm Cu, +/_ 600 ppm Pb and 500-5000 ppm Zn. Getty Oil located a number of other base metal anomalies of similar style but these were not sampled or followed up. Petrological studies carried out by Getty Oil indicated propylitic alteration (calcite, epidote, chlorite).

GEOCHEMISTRY

REGIONAL EXPLORATION

- stream sediment sampling -A total of 79 BCL stream sediment samples were collected within the ATP. The Thuriba area has a moderate BCL gold background. The threshold level for BCL anomalies was therefore arbitrarily set at 0.7ppb. Eleven anomalous samples outline five areas which required follow up. In order of interest these were:

1. Southern Thuriba - Dumfries Creek - 3.1, 13.4, 11.1 ppb 2. Southern Thuriba - Three Mile Gully - 1.6 and 15.5ppb 3. Grantleigh Siding 4. Southern Thuriba - Twelve Mile Creek - 1.05ppb 5. Southern Thuriba - Twelve Mile Creek

- rock chip sampling -31 rock chip samples were collected from within the tenement. At the Rookwood Homestead Grid Bligh Management Pty Ltd sited a soil sample grid over an area of ferruginous and gossanous rubble 2.5km E of Rookwood Homestead. All rock chip samples collected by Ross Mining contained only background levels of gold except one sample which returned 0.16ppm Au and 105ppm As. Samples collected from the Grantleigh diggings contained only background values of Au, As and Ag. Rock chip samples collected from the Thuriba Homestead area returned low gold values.

LOCAL EXPLORATION

Southern Thuriba area stream sediment sampling -Follow-up sampling of BCL anomalies confirmed the Twelve Mile Creek East anomaly. The creek drains Rannes Beds phyllites which contain sporadic quartz veining. rock chip sampling -Mapping and rock chip sampling of the Camboon Andesite, Oxtrack Formation and Boomer Range sediments failed to locate any mineralisation.

Grantleigh area stream sediment sampling - Anomalous samples in the Grantleigh area were not confirmed during follow up sampling. rock chip sampling - Background Au values were returned from rock chip samples of quartz vein in the Rannes Beds sediments.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -Gold diggings have been recorded in the Rannes Beds west of Grantleigh Siding but no production details are available.

SUMMARY:

GEOLOGY

REGIONAL -The ATP is dominated by The Devonian-Carboniferous Connors Volcanics, flanked by tightly folded and strongly cleaved Permian sediments of the Upper Permian Boomer Formation. Spilitic lavas of the Rookwood Volcanics occur in the southern part of the ATP.

MINERALISATION/ALTERATION -Copper mineralisation has been recorded in the Connors Volcanics within the ATP area. It occurs as native copper, oxides, sulphides and in irregular veins.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION -Samantha explored the western half of the ATP for volcanogenic base metals, and gold using stream sediment sampling (-80 mesh). An area anomalous in arsenic was highlighted but follow- up sampling failed to locate any mineralisation.

The SE half of the ATP was briefly held by Peabody of Australia Pty Ltd. Rock-chip sampling was conducted.

GEOCHEMISTRY

Stream sediment sampling -Four anomalous BCL samples outlined three (3) areas which require further investigation.

(1) Western Melaleuca Creek - An anomalous sample (0.95 ppb Au) drains Rannes Beds and Connors Volcanics.

(2) Four Mile and Paddock Creek - Two anomalous samples drain Rannes Beds and Connors Volcanics.

(3) Upper Four Mile Creek - An anomalous sample (1.6 ppb Au) drains Rannes Beds.

Rock chip sampling -No significant Au values were recorded from rock-chip sampling. Regional reconnaissance has outlined two areas of hydrothermal breccia development in the western part of the ATP. The northern-most breccia (1.1 x 0.3 km) on the eastern side of the diorite intrusive south of Mount Benmore, comprises angular fragments of andesite, amygdaloidal basalt, conglomerate, shale and sandstone in a carbonate/quartz cement. Only minor sulphides were observed. No gold was reported from rock-chip samples collected from this unit.

Extensive brecciation and silicification were also developed adjacent to a thin (50 m) porphyritic quartz feldspar rhyolite SE of Leura Homestead. No Au mineralisation was recorded from rock-chipping.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -Follow-up rock chip, and BCL stream sediment sampling failed to repeat earlier anomalous values (believed to be due to analytical errors by Australian Laboratory Services) and therefore no further work was carried out on the ATP.

SUMMARY:

GEOLOGY -

REGIONAL -The oldest rocks in the prospect area are folded Early Carboniferous tuffaceous sediments which are overlain by oolitic limestones of the Rockhampton Group.

Much of the region is covered by Cretaceous basalt, in turn overlain by indurated coarse-grained, well- rounded alluvial gravels which may also be Cretaceous. Cretaceous trachytic plugs and flows also occur in the area.

There is no recorded mining activity within the tenement area.

GEOCHEMISTRY One soil sample, three rock-chip samples and twenty three stream sediment samples were collected and assayed for gold using the BCL method. No anomalous gold values were identified.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -Geological reconnaissance by P. Ravenscroft and M. Scott identified two areas of very old alluvial workings, one at upper Limestone Creek and one at Black Flat on Limestone Creek crossing. The Upper Limestone Creek workings are in stream alluvium while the Black Flat workings contain some of the slightly indurated gravels above the Cretaceous basalt.

Another area on the basalt between Bonley Creek and Middle Creek shows evidence of somewhat more recent digging - possibly involving treatment of gravels overlying the basalt for gold.

SUMMARY:

GEOLOGY -

REGIONAL -The Authority to Prospect covers approximately 60% of a block of andesitic and tuffaceous volcanics known as the Native Cat Andesite, which is overlain unconformably by Upper Cretaceous basalt and trachyte. The Lower Cretaceous Stanwell Coal Measures are partly exposed in the south-east corner of the ATP.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION -BHP conducted extensive base metal exploration between 1968 and 1972, in an area immediately south of the prospect. No economic mineralisation was encountered.

In 1977, Mineral Deposits Limited explored for base metals and precious metal mineralisation, southeast of ATP 4868M. Stream sediment sampling outlined an anomalous zone associated with the contact of the Native Cat Andesite and sediments of the Stanwell Valley. Ground geophysics was run, and one core hole was drilled but gold was below detection limit.

In 1982, Golden Reef Mines explored the Golden Spur Creek and associated workings for placer gold deposits. This creek drains south from the boundary of the ATP. A total of 16 bulk alluvial samples were collected and analysed for coarse gold. A reserve of 60 000 to 100 000m3 with an average grade of 0.75 g/m3 Au was defined, but lack of water precluded mining.

The source of the gold was attributed to a dioritic intrusion in the Native Cat Andesite. At the intrusive contact, gold seems to occur in association with iron and copper sulphides in chloritic altered andesite. No mineralised quartz veins were identified.

The Stanwell Gold Field was gazetted in 1889. The Native Cat Mine was the only mine worked on the field. Production figures are not available. It appears that the gold was associated with pyrite in quartz veining in the Native Cat Andesite.

Although alluvial gold was found in several creeks draining the Native Cat Andesite, the only workings were in Golden Spur and Native Cat Creeks.

GEOLOGICAL MAPPING -

GEOCHEMISTRY

STREAM SEDIMENT SAMPLING -Stream sediment anomalies defined by the initial sampling programme were followed up with little success. Rock-chip sampling and geological mapping were conducted simultaneous with stream sediment mapping in order to gain an overview of the Native Cat Andesite. Five main areas of interest were investigated.

Within area 3, a flow-banded ignimbrite (?) unit was mapped on the crests of ridges. The ignimbrite (?) contains small lithic and andesitic clasts and fine pink quartz veining. Overall the unit shows strong flow characteristics and varies from horizontal to vertical in dip. It is weakly siliceous in areas and may be distinct from the Native Cat Andesite, although this is not mapped as such on the Rockhampton 1: 250 000 Sheet.

SUMMARY:

GEOLOGY -

LOCAL - The tenement is within the Rockhampton Block which contains structurally preserved remnants of the Yarrol basin. The area basically comprises a N to NW striking sequence of Devonian to Upper Carboniferous marine sediments (Yarrol Basin Sequence) and Upper Permian lacustrine sediments (Dinner Creek Conglomerate) which has been irregularly intruded by the Bouldercombe Intrusive Complex (quartz gabbro to diorite and monzonite). At Mt Lion near the NW corner of the ATP, there is a small acid to intermediate volcanic complex of Upper Cretaceous age which intrudes and overlies the Yarrol Basin sequence. An extensive NW trending belt of volcanics occurs at Native Cat Range to the W of the area. NE & NW trending fault sets predominate.

MINERALISATION/ALTERATION - Known gold mineralisation within the ATP have a spatial relationship with N trending intrusive contacts along the E periphery of the Bouldercombe Complex. The work in this tenement (5029M) is concurrent with work in ATP 5128M. Nine goldfields have been proclaimed in the Rockhampton 1:250,000 sheet area, and parts of five of them (Morinish, Ridgelands, Rosewood, Stanwell and Mt Morgan) occur within, near, or between the two ATP areas. Hector Reef is in the Gavial Creek catchment in the SW corner of ATP 5029M. The ATP is within an area of scattered but widespread, small scale historic gold production.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION - Previous exploration by CSR Aluminium Ltd. (ATP 3544M); Haoma North West NL. (ATP 3546M); BHP Co. Ltd (ATP 426M); and Dampier Mining (ATP 532M).

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE - The most prospective targets are the old Hector Mine and the N & W continuation of the intrusive-sedimentary contact that hosts the mineralisation; the Mt Lion acid volcanic/intrusive plug; and the Gracemere area. But due to circumstance beyond the control of Andsus, no additional work on the title area was conducted and the ATP area lapsed at the conclusion of the first year of tenure.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -To evaluate auriferous alluvial and eluvial deposits along Golden Spur Creek and its tributaries.

GEOLOGY

LOCAL -The local geology comprises the Triassic Native Cat Andesite which consists of andesitic flows, tuffs, quartz trachytes and minor trachyandesites. Osborne (see PREVIOUS EXPLORATION below) reported a previously unmapped dioritic intrusion located in a NS trending zone along Golden Spur Creek near the Native Cat Mine. Diorite intrudes the Native Cat Andesite and is considered to be of Upper Triassic age.

PREVIOUS EXPLORATION

The area has been previously mapped by M.E. I'ons and R.J. Osborne (CR's 11536 & 13789).

GEOCHEMISTRY - stream sediment sampling -limited alluvial sampling was carried out.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -Limited alluvial sampling was conducted. Time was spent searching for a suitable dam site to establish a water supply for an alluvial testing plant.

Approaches were made to the holder of an adjacent lease (ML 1047) with a view to a joint venture , however a third party was already negotiating with the holder.

In the second six-monthly period further negotiations took place, however poor gold price and low value of the dollar prompted relinquishment of the title.

TRANSFERS, JOINT VENTURES, etc: Mr Sam Munn's prospected in the area of Cox Creek on behalf of Andsus Pty Ltd. A total of 60 samples of about 20-30 kg each were collected and processed through Mr Munns gravity separation plant. All samples contained visible gold which attracted some interest from potential joint- venture partners, and in July 1988, Northpac Resources NL conducted a limited rock chip sampling programme in the Cox Creek area with disappointing results. A limited programme of BCL sampling was completed in November 1988 by Applied Geology Associates on behalf of Andsus, and returned results supporting the earlier work of Mr Munns. LEASES TAKEN OUT: COMPANY REPORT Nos: Open File-18328, 20250,21073 Confidential-

SUMMARY:

Exploration was confined to two main areas

Initial work at Cox Creek revealed traces of fine gold. Limited mapping and rock-chip sampling was conducted by a potential farm-in partner but results were negative. BLEG samples collected by Andsus Pty Ltd yielded consistent, low positive assays for gold but neither the significance of the results or the origin of the gold was determined.

Rock-chip samples from the Emu Creek area returned highly anomalous gold values. Later mapping and more widespread sampling outlined a zone of low grade surface gold mineralisation associated with fracturing and quartz veining within acid-intermediate lavas. An area of 350 x 70 m may have subsurface potential, however due to the results obtained and the lack of widespread diagnostic alteration, further work cannot be justified.

The ATP was allowed to lapse at the conclusion of the second year of tenure.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -To search for gold mineralisation in an area known to have sustained historical gold production.

GEOLOGY -

LOCAL -Table 3 presents a useful stratigraphic section. The 1: 100 000 geology map would be useful to copy.

EXPLORATION

PREVIOUS EXPLORATION -1984/5 CSR Aluminium Pty Ltd held ATP 3555M (CR 14883). 1968 - BHP held ATP 294M (CR 2505). 1980 - BHP explored under ATP 3150M (CR 11322).1968-70 - Dampier Mining held ATP 523M (CR 4359).

This report presents a reasonably detailed literature review of the goldfields of the area, including but not limited to, Ridgelands, Rosewood and Mount Morgan.

GEOLOGICAL RECONNAISSANCE - There is quite extensive evidence of alluvial workings in the upper tributaries of Bottle Tree and Cedar Creeks (Known as the Herbert Creek Diggings). According to local residents, the workings may extend downstream onto the western extremities of the ATP.

In the 1940's an adit was driven into the adjacent foothills of the Gogango Range at approximately GR 993 607 (8950). It is believed that auriferous quartz veins in this area may have been the source of some of the gold recovered from the nearby alluvial workings.

Chinamans Gully-Stockyard Creek area - This prospect lies to the east and just beyond the boundary of the ATP and was another area of minor historical gold production.

Gold has been reported from the extensive lateritised Tertiary deposits to the southeast of the ATP, near Wowan. The presence of similar Tertiary sediments within the ATP warranted further exploration.

Cox's Creek - Pan concentrate sampling during this period revealed fine gold. A detailed soil and/or rock chip sampling programme is proposed for the future. The geology of this area appears more complicated than the simplified geology map indicates. Andesitic and gabbroic rocks were noted during field inspections. Intrusive contacts with granitic-textured rocks, localised quartz and calcite veining and minor zones of alteration were noted in the vicinity. It is probable that the alluvial gold in Cox's Creek is derived from gold-quartz veins related to granitic intrusions and hosted by the Lower Permian Rookwood Volcanics near the catchment divide. A local resident reports auriferous quartz veins from the Ram's Head Gully area but this has not been substantiated.

Cobbler Mountain and adjacent hills - All the streams and gullies draining west from these hills were sampled and panned with a few colours showing up (eg. GR 955 907-8950). The catchment of this creek is immediately west of the headwaters of Fred Creek which BHP previously outlined as anomalous and drilled. Mr Peter Ravenscroft indicated the possibility of old workings (hard rock quartz veins/fissures) at about GR 8950 - 022 920, but this area was not visited and cannot be substantiated.

Emu Creek - Emu Creek Workings was the site of fairly extensive alluvial diggings in the 1870's to 1880's. During field reconnaissance by Applied Geology Associates, Mr Sam Munns demonstrated evidence of considerable pitting for about 1 km along the unnamed creek at GR 8950 - 020 927 approx. This creek is known by locals as Emu Creek, although another Emu Creek is shown on the Ridgelands 1: 100 000 topographic map and is some kilometres further north. Mr Munns is not aware of any gold workings in the latter vicinity and presumes that the latter is indeed the Emu Creek.

Rosewood Scrub Diggings - These diggings are reputed to occur in the vicinity of GR 8951 - 950120, within the current ATP area. This area was examined and although no evidence of old workings were visible, a sample of alluvium from GR 8951 - 943 135 returned a single large colour of very clean gold.

The Champion Mine - This mine at GR 8851 - 013139 lies to the south of, and outside the main part of the Rosewood Goldfield, but within the boundary of the current ATP. Field inspection failed to locate any evidence of previous mining. There is reference to this mine in the 1898 ARDM which states that "exceedingly good returns from the Rosewood Champion P.G. United" and .." since this claim first started, 21 tons of stone crushed gave the handsome return of 210 oz 4 dwt of gold". The mine struck heavy water problems at 90'. Descendants of Alfred Kele, who first opened the mine, still live in Rockhampton and may be able to provide more information on the further history of the mine and it's precise location.

SUMMARY:

EXPLORATION -

Cox Creek prospect - Mr Sam Munns has been prospecting in the area of Cox Creek on behalf of Andsus Pty Ltd. A total of 60 samples of about 20-30 kg each were collected and processed through Mr Munns gravity separation plant. All samples contained visible gold which attracted some interest from potential joint-venture partners, and in July 1988, Northpac Resources NL conducted a limited rock chip sampling programme in the Cox Creek area with disappointing results. A limited programme of BCL sampling was completed in November 1988 by Applied Geology Associates on behalf of Andsus, and returned results supporting the earlier work of Mr Munns. One shallow pit and mullock heap was located in the area during reconnaissance. It is more likely that documented gold occurrences in Cox Creek refer to areas further up creek and closer to the old Westwood gold-platinum workings.

Work by other companies locally within the Rookwood Volcanics suggests that the formation may be prone to high background concentrations of gold and other elements.

Emu Creek Prospect - This area was the focus of considerable historical prospecting and alluvial mining but production figures are unavailable and are assumed to be relatively insignificant.

Several grab samples returned high gold values and prompted further drainage and rock-chip sampling. Detailed mapping with the view to delineating drill targets was proposed. other areas - Reconnaissance failed to find the "Rosewood Scrub Workings" however the Champion Mine was located. Further work is proposed to explore the vicinity of the mine and surrounding areas.

FINAL COMMENTS - This report contains good location diagrams with some geology plotted also. Copy at a later date.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -To search in an area with historical gold production, for epithermal/mesothermal gold mineralisation.

GEOLOGY -

REGIONAL -Regional mapping of the area by Kirkegaard (1970) has shown this area to be underlain by the Early Permian Rookwood Volcanics. For the current investigation, the area was mapped with the aid of a 1: 5000 scale black and white airphoto (8950 Mt Morgan, Run 2, No 261 flown 10.6.86). Airphoto lineaments within the area are predominantly orthogonal (N-S and E-W) and are defined by the drainage pattern which appears to be partly joint-controlled in a north-south direction.

EXPLORATION -Exploration consisted of a literature review, geological reconnaissance, and limited geochemical sampling and mapping. Results of this work is detailed in summaries for CR's 18328 & 20250.

Initial exploration involved low-density stream sediment sampling with two stages of high-density follow-up stream sediment sampling. Limited rock-chip sampling was also carried out. Two areas (named Area A and Area B) were considered to have low-order BCL anomalies.

Follow-up work during the second six month period highlighted two prospects.

Folly 236 Prospect - Follow-up investigations were conducted in the vicinity of a silcrete outcrop which returned anomalous assay values. Resampling returned background values for Au and most other elements except for slightly anomalous Hg (600ppb) and Te (1000ppb). A combined -80 and -40 mesh reconnaissance soil survey conducted across the subcrop returned consistently low values for all elements analysed.

Rock-chip sampling of limonitic gossanous float on top of a weakly siliceous calcrete horizon returned anomalous geochemical values as well as confirming the rocks represented hydrothermally silicified, pyritised and weathered facies. Most high values were attributed to scavenging and leaching processes.

3 costeans were put in to improve exposure. The walls of the costeans were mapped and channel sampled.

Treepusher Prospect - Ground reconnaissance located highly siliceous pyritic material approx. 5 km north of the Folly 236 Prospect costeans. Follow-up surveys included medium-density -80 mesh stream sediment sampling and minor rock chip sampling. The -80 mesh stream sediment samples returned consistently low analytical values. The rock chip samples returned significant anomalous values including 0.46ppm Au, 900ppm Cu, 175ppm Pb, 54ppm Ag, 200ppm Mo, 1% As, 20ppm Bi, 3ppm Hg, 11ppm Sb(Maximum values recorded for all samples).

Ground reconnaissance in the vicinity of the Treepusher Prospect located a highly lateritised breccia within an area of extensive Tertiary laterite cover. A costean 20 m long cut perpendicular to the breccia subcrop exposed a highly ferruginous/lateritised soil horizon overlying the leached horizon and poorly distinguishable breccia and gossanous fragments. Channel sampling of the costean resulted in anomalous Au, As, B and Sb.

Three (3) reconnaissance -80 mesh soil sampling traverses were conducted with samples collected every 100 m.

Early in June 1989, QMC announced cessation of all minerals exploration activity in order to concentrate on developing the Kunwarara magnesite deposit. The ATP was relinquished on 7th June 1989.

GEOLOGY

The stratigraphy of ATP 5340M is represented from oldest to youngest by -: Yarrol Basin Sequence, Rannes Beds, Youlambie Conglomerate, Rookwood Volcanics, Cretaceous sediments and Quaternary cover. Palaeozoic serpentinite, Siluro-Devonian granodiorite, and a small undifferentiated Permian/Mesozoic intrusive, crop out near the boundary of the ATP.

Geology is presented at 1: 50 000 which gives quite a good topographic base, however, the geology is an enlargement from the BMR 1: 250 000 Sheet (Duaringa) and appears unmodified.

GEOCHEMISTRY

Stream sediment sampling - exploration involved low-density stream sediment sampling with two stages of high- density follow-up stream sediment sampling. Limited rock-chip sampling was also carried out. Two areas (named Area A and Area B) were considered to have low-order BCL anomalies.

Area A comprises greenish, fine-grained intermediate volcanics or tuffaceous rocks containing carbonate/calcite veining and minor quartz veining. Dolomitic limestones (variably oolitic), and fine-grained sedimentary rocks are also present. The rocks are moderately to very highly sheared, and locally brecciated. Sporadic silicification and widespread epidotisation are evident. Initial follow-up stream-sediment sampling in Area A revealed an increase in BCL results from 450 to 1500 ppt approximately 1 km upstream, but follow-up ground investigations and sampling were not encouraging.

Rocks of Area B include dark-green, fine-grained volcanic and/or tuffaceous rocks, brown-yellow siltstones and other fine-grained sedimentary rocks. The rocks are moderately to highly sheared and contain abundant carbonate veins and minor epidote veins. Second stage follow-up stream sediment sampling failed to indicate significant mineralisation.

One silcrete outcrop yielded anomalous assay values.

SUMMARY:

Reason for acquisition - The area was acquired to follow up a previously reported (BHP/INSEL) rock sample (RG42) anomaly of 2.61 g/t Au. The anomalous rock chip was mapped as being in a coarse volcanic breccia zone between a volcanic sequence (basic lavas, tuffs, cherts, dacites and limestones) a gabbro/diorite.

Exploration -

Stream sediment sampling - Preliminary stream sediment sampling showed two samples in Stoney Creek with values of 11.4 ppb and 5.05 ppb Au, and this creek is thought to drain the anomalous area.

Stream sediment sampling was conducted over the ATP. BCL samples were analysed for gold; -80 mesh samples were assayed for Cu, Pb, Zn, As, Bi, Sb, Fe, Mn, Ni, Cd, Mo, Co, Cr. Anomalous values (5 to 89 ppb Au) in stream sediment samples collected from Stoney Creek and its' tributaries suggested a target somewhere on the south-west side of Stoney Creek. Although some high Au values were recorded form - 80 mesh samples (430 & 410 ppb) taken from Stoney Creek, most were unremarkable.

Soil sampling - A grid was defined and then sampled at 25 m intervals. BCL assays show spot highs of 90-118 ppb in a zone of greater than 5 ppb which measures 225 m x 500 m. Within this zone there are two zones of >10 ppb. These zones appear to be related to a vesicular andesite (or possibly thinner, unmapped epidotised andesite bands) and gabbro respectively.

Rock chip sampling - Epidotised andesites were suspected as the cause of the soil anomalies and were subsequently sampled and assayed. The highest value was 0.42 ppm.

Drilling - Five (5) reverse circulation percussion drillholes were drilled for a total of 478 m. Assays of cuttings, and drill logs are provided. Only one assay reported Au greater than 0.04 g/t (MRDH2 which reported 0.34 g/t Au). Ag assays were all <1 ppm. Problems were encountered differentiating between a fine-grained gabbro intrusive and altered andesite in chip samples and the intrusive boundary is not particularly clear.

Local Geology - Company mapping shows a sequence of limestone (marble), chlorite schist, andesite lava, calc-silicates, andesites and andesite/basalts, and gabbro/dolerite. Epidote rich zones within the andesites are thought to be associated with the gold mineralisation.

SUMMARY:

REASON FOR ACQUISITION - This ATP was acquired for gold exploration in an area which showed lithological similarities to another area (ATP 5371M - "Matryoshka") which returned anomalous gold values.

GEOLOGY - Local - Mudstone, sandstone and greywacke are the dominant lithologies within the A to P but float of ultramafic rock is plentiful in the north of the area. Minor andesitic volcanics occur in the far west of the ATP.

EXPLORATION

GEOCHEMISTRY

Stream sediment sampling- BCL and -80 mesh samples were collected during first phase stream-sediment sampling. Anomalous gold values (5.3 to 8.2 ppb Au) are believed to be related to the ultramafic rocks or units in contact with them. Assay values and sample-location maps are included.

Assay results from follow-up sampling in the "Just in time" area yielded 8 - 33 ppb Au; values in the "Kunwarara" area recorded 4 - 19 ppb Au.

Soil sampling - Just in Time Prospect -Two soil lines were run. The first around the main Just in time Workings (max. value of 139 ppb Au), and the second along a spur between the creeks (returned generally low values). Kunwarara Prospect - A 500 x 400 m grid was laid out and soil samples collected every 25 m. A linear gold anomaly within the schist had a maximum value of 143 ppb.

PROSPECTS

Just in Time Prospect - This prospect covers Upper Native Bear Creek and the contact between the ultramafics and feldspathic schists. A number of old pits and trenches were found in the area, predominantly within the schists. The majority of the creeks had previously been worked for alluvials. The Just in Time Workings were dug on thin (< 0.5 m) quartz veins with a maximum strike length of approximately 70 m. Assays of rock chip samples taken from these quartz veins returned values from <0.1 to 22.2 g/t Au.

Kunwarara Prospect - This prospect is situated along the contact between quartz-feldspar schists and fuchsite altered metamorphics. A 500 x 400 m grid was laid out and soil samples collected every 25 m. A linear gold anomaly within the schist had a maximum value of 143 ppb.

SUMMARY:

REASON FOR ACQUISITION OF TITLE - To target the Native Cat Andesite which may host epithermal precious metal mineralisation.

GEOLOGY -

LOCAL - The ATP is in two blocks, and covers the S and W parts of the Triassic Native Cat Andesite. The Andesite is exposed along the areas of the Mount Candlelight Syncline, forming a high plateau up to 250 m above the surrounding country. It is thought to be a terrestrial volcanic pile resulting from post-orogenic volcanism, following late Upper Permian orogeny. The volcanics dip gently towards the axis of the syncline, which trends N-S. Within the E block of the ATP, the Native Cat Andesite is overlain by Quaternary alluvium and gravel. The E-W Stanwell Fault runs along the S edge of this block, and this fault terminates the andesitic outcrop. In the W block of the ATP, the Native Cat Andesite unconformably overlies the Upper Permian Dinner Creek Conglomerate (conglomerate, lithic arenite & mudstone). The Upper Permian Moah Creek beds of similar composition, crop out in the west of the block.

MINERALISATION/ALTERATION - The ATP covers part of the Stanwell Gold and Mineral Field.

REGIONAL EXPLORATION

PREVIOUS EXPLORATION - Previous exploration by BHP (ATP 5488M); Mineral Deposits Limited; and Golden Reef Mines. The Stanwell Gold Field was gazetted in 1889 but only one mine, the Native Cat, was worked on the field. It appears the gold was associated with pyrite in quartz veining in the Native Cat Andesite. Alluvial gold was found in several creeks draining the Native Cat Andesite, although the Golden Spur and Native Cat Creeks were the only ones worked.

GEOCHEMISTRY

- stream sediment sampling - A stream sediment program was completed over the ATP, with 57 samples collected. Only four samples assayed greater than 0.90 ppb Au. The maximum assay was 1.59 ppb Au and was located adjacent to an assay of 1.07 ppb Au. This area of the ATP is the only one with a multiple anomaly, the other two being isolated stream anomalies with no support from surrounding watercourses. All four anomalous creeks drain S from the Native Cat Range in the E block of the Authority.

- rock chip sampling - Six rock chip samples of veining, alteration and breccia were collected from the area with the two adjacent stream sediment anomalies. The results were discouraging. After further reconnaissance of this area with negligible results it was concluded the anomalous stream samples were a result of veining and faulting, but due to poor assay results and the small size of the quartz veining, no further work is warranted on this area.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE - No economic precious metal mineralisation was located, therefore no further exploration is considered justified.

SUMMARY:

GEOLOGY -

LOCAL - The three anomalous drainages were investigated in an attempt to define a possible source of the anomalies. The adjacent creeks that returned 1.07 & 1.59 ppm Au are moderately to deeply incised. Geology of the area includes purple to green andesite, predominantly fine-grained and very weathered. Minor amounts of fine rhyolite float was also present in the creeks. Between the two creeks, approximately 300 to 400 m upstream, sparse outcrops of weathered andesite containing small stockwork quartz and calcite veins are present. Minor epidote and zeolite alteration is observed and the quartz is massive to vuggy and crystalline, with minor limonite after pyrite cubes. Veining is only centimetre scale. Heavily iron-stained andesite fault breccia is also present in this area, although sparse in occurrence. Investigations of the drainage area that returned 1.31 ppb Au revealed no obvious source of this anomaly. The creek drains low hills comprising very weathered, fine to porphyritic green andesite, with minor diorite float in the watercourse itself. No mineralisation or hydrothermal alteration was observed in this area and it is concluded that the anomaly may be related to a diorite intrusion. Diorite intrusions in the Native Cat Andesite have been the subject of previous exploration and gold productions to the immediate W of this area.

SUMMARY:

REASON FOR ACQUISITION OF TITLE -To evaluate limestone deposits on land adjacent to the existing Mt Etna Limestone Mine.

GEOLOGY -

Local -The limestone at Mt Etna is of Lower to Middle Devonian age and is underlain by older shales and greywackes of marine origin, and also underlain by serpentinite and minor gabbros.

EXPLORATION -

Drilling -Two diamond core drillholes (DDH 88-1, DDH 88-2) were sunk in 1988. Drill core was logged and sectioned for storage and assaying. Two angled rotary-percussion holes (DHH 90-1 and DHH 90-2) were drilled in 1990. Drill-cuttings were sampled and split for assaying. The drilling proved that limestone of suitable grade and quantity extends beyond the existing lease boundary. Apart from this earlier drilling (reported in CR 22296), ten drill holes were sunk to enable water monitoring to be conducted.

Geotechnical investigations - Highwall and slope-stability studies were conducted in the mine area to determine the quantity of limestone sterilised along the northern boundary of the Mining Lease and the ultimate depth to which mining could extend. Blast design considerations were also investigated.

FINAL COMMENTS/REASON FOR RELINQUISHMENT OF TITLE -Results of the studies conducted indicate that significant resources of limestone suitable for cement making extend northwards from the existing area being mined.
