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. RECORDER:G.Simpson DATE:12/12/94. COMPANY REPORT (and ATP) SUMMARY SHEET CR:1562 STATUS:open file TITLE:Three separate reports on operations in respect of ATP 234M for the three month periods ended 2/4/1964, 2/7/1964, & 2/10/1964. AUTHOR(S):D.J. Matheson DATE: ATP/EP No.:ATP 234M COMPANY HOLDING TITLE:Capricornia Mineral Development Company Pty Ltd. COMPANY SUBMITTING REPORT:Capricornia Mineral Development Company Pty Ltd DATE GRANTED:20/1/1964 PERIOD: 1:100 000 SHEET NAME(S):Marlborough (8852) 1:250 000 SHEET NAME(S):Saint Lawrence (SF55-12) LOCATION:17 km SSW of Marlborough MINING DISTRICT: MINES/PROSPECTS: EXPLORATION TARGETS\MODELS:Chrysoprase 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. RECORDER:M.A. Hayward DATE:21/11/1994.

Moore DATE GRANTED:10/4/1964 PERIOD: 1:100 000 SHEET NAME(S): Marlborough (8852), Ridgelands (8951) 1:250 000 SHEET NAME(S): St Lawrence (SF55-12), Rockhampton (SF56-13) LOCATION: Region south of Marlborough MINING DISTRICT: MINES/PROSPECTS: EXPLORATION TARGETS\MODELS: Chrysoprase TRANSFERS, JOINT VENTURES, etc: LEASES TAKEN OUT: COMPANY REPORT Nos: Open File- 3357 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. RECORDER: Simon Crouch DATE: 28/03/1994.
