Abstract
The Maniwaki Basin Project was initiated in late 1979 following
Shell's decision to explore for Balmat-Edwards type Pb-Zn deposits in the main sedimentary basin of the Grenville Supergroup in the Gatineau region of Quebec. A specific area was initially selected within the framework of the larger exploration program to carry out orientation surveys. The area located 80 km north of Hull and covering approximately
280 sq. km was selected on the basis of its well known high grade zinc occurrences and good geological control provided by the very recent detailed mapping of M. Gauthier for the Quebec Government.
An Input survey was flown over the area in April 1980 to a) establish the airborne responses of the known Zn occurrences and b) to obtain structural information from the A.E.M. and aeromagnetic data. Ground work in 1980 included detailed mapping, geochemical surveys (rock, soils and stream sediments) and V.L.F. coverage over the
Lafontaine &posit, ..eitch and Parker zinc zones and similar reconnaissance surveys over 14 selected Input anomalies to evaluate the effectiveness of these techniques in the project area.
'rile Leitch occurrence, essentially massive sphalerite mineralization only, produced no Input response. The Lafontaine deposit, which has associated conductive iron sulphides (hand specimens) could not be properly evaluated because of culture noise interference (nearby electric transmission line). Aeromagnetic data proved useful in outlining formational units in areas of overburden cover.
Distinct zinc, lead and cadmium anomalies are associated with the known zinc occurrences as shown by the soil (A+B horizons) and stream sediment surveys. Minor element (Pb + Zn) dispersion in host
rocks however appears to be very restrictive W/P mineralized zones
ie., strong anomalies detectable for only several meters away from deposits. V.L.F. survey., over mineralized zones produced weak to i questionable responses. Reconnaissance work identified the presence of magnetite/graphite and/or pyrrhotite mineralization as the probable cause for several of the selected Input anomaly areas, although most
to date remain unexplained. Several of the Input anomalies have f associated soil geochemical anomalies with zinc concentrations ranging from 700 ppm to 4800 ppm. The selection of geophysically anomalous
areas was guided largely by the recognition of the favorable lithological association of dolomitic marble and/or calc-silicate rocks. On the
basis of this data, six of the fourteen anomalies were staked and
negotiation for acquisition of the remaining patented lands was undertaken.
Subsequent detailed mapping/geochemical su.veys would thus enable
target selection for the first phase of drilling. Reconnaissance
mapping/geochemical surveys are proposed for the 1981 field season for
those areas north, south and east of the present project area to evaluate the potential of other sectors in Font Laurier Basin. As these more conventional exploration surveys are being carried out on
the regional scale, it is intended the Maniw:aki Basin Project area will
continue to be the lieu of further diverLfied orientation work. Worthy of further consideration as alternate exp$oraticn•techniques appear to
be basal till, well water, I.P. and possibly gravity surveys. Table of Contents page

Efflowsawsurn 1.0 INTROD':;'C:TI ON
The Maniwaki rasin Project was initiated in late 1979 following recommendations by R. Van Ingen to work in an area recently mapped by Michel Gauthier (1978: masters thesis). By closely examining Gauthier's geological mapping efforts in an area known for its zinc mineralization, it was Shell's intention to establish the exploration applicability of this data as well as the economic base metal potential of the area as a whole. Orientation,geological, geophysical and geo- chemical surveys were also carried out over known zinc occurrences to determine the effectiveness of specific ground techniques to guide future exploration work. Finally, an A.E.M. Input survey was flown over the study area to test the usefulness of this system in providing structural (aero- magneticcs) and possibly drill target selection (electromagnetics) information.
Compilation based on assessment and government geological reports of this region was prepared by Joan Castonguay in the fall of 1979. Sub- sequently, a 1500 line-km Mark VI lncut survey was completed in May 1980. Field work began in early July and consisted largely cf mapping the Lafontaine deposi'.. and Leitch and Parker showings. Systematic close-spaced geochemical surveys including whole rock (major & minor elements), soil profiles (A, B & C horizons) and stream sediment sampling (where possible) were carried out over these siowings. Attempts at determining Ph in streams and soil did not prove sufficiently sensitive to be of any practical use. Geophysical E. M. 16 rJ..L.F.) profiles were also obtained over the same flagged lines of th soil survey grids.
Dering the latter part of thr„ field season similar, but less detailed, surveys were undertaken over fourteen (14) selected airborne anomalies (azu x 4). Selection Of the anomalies was based on the standard conductor parameters as well as favorable gec.logicel setting. This report presents a) the results of the orientation surveys over the zinc occurrences in section I and b) the results of the field investigation over the seleci'r°d airborne anomalies.
2.0 PROPERTY, DESCRIPTION AND LOCATION
The study area covers approximately 265 sq. km and is bounded by latitudes 40° 17' 20" and 46° 04' 2G" and longitudes 760 02' 00" and 75° 53' 30". The center f the area is located 80 km north of Hull and 10 km south of Maniwaki (Fig. 1) . The region is well develop ed with about one half of the surface area being open farmland. All townships have been subdivided into ranges and surveyed lots, a great nus er of which the mineral rights belong to the land owner and not the crown as is the case for the others. 2

FIG.1 Laa<<•tian MaA The four known zinc occurrences are presently held directly by St. Joseph Exploration, as is the case for the Bouchette Showing or they have been optioned to St. Joe from Cominco (ex. the Lafontaine deposit in Northfield Twp and the Leitch and Parker showings in Northfield and Wright Twps respectively) (see Fig. 2).
Shell staked a total of forty-three (43) claims in late October 1980 over seven airborne anomalies, namely anomalies E,I,J,K,N,O, and S (annex 4 - property map). Acquisition of the remaining lands is currently being negotiated by Shell's Land Dent. from Calgary. Lands set for acquisition cover anomalies C,D,H,P,Q,R, F and G.
3.0 ACCESS AND LOCAL RESOURCES
The topography of the region is generally subdued but locally quite hummocky. Local re'ief likely results from .ronounced preferential weathering due to the great variability of bedrock lithologies. The flat areas clay and sand covered river valleys,account for the majority of the agricultural lands while the more hilly terra.ns are forest covered with an equal mixture of coniferous and deciduous (hard and soft wood) trees.
Access in this area is excellent. Numerous secondary lumbering and agricultural roads connect with Highway 105, the principal N-S artery which parallels the Gatineau River on its west shore across the entire map area. A small airport (non-commercial) is located just south of Maniwaki on the east side of Highway 105 and a railroad system joins Maniwaki with the Hull/Ottawa district.
4.0 PREVIOUS WORK
The region has been prospected since at least the beginning of the .century. Reconnaissance mapping was done by Aubert de la Rue (1944,47, 53,57) at the scale 1:63)360 for the Bureau des Mines du Quebec. The Geological Survey of Canada also produced a map of the area. The area in which we worked was mapped at the scale of 1:50,000 by Michel Gauthier in 1978.
A lot of exploration work by private companies was done between 1948 and 1952. During this period the Lafontaine prospect entered production (1950-•1951) and.produced some twenty thousand tons of concentrated ore. Norzinc Mines, Consolidated Mining and Smelting, Learidge, Cherry Lake Mines, Leitch Mines, Bowsingues, Tower Mine, St-Joseph Exploration are among the companies that spent considerable time and money during this period to find more zinc mineralization. All the work done was essentially concentrated around the known zinc occurrences.

More recently, Cominco Ltd., Selco, St-Joseph Exploration, Beth Canada Exploration Limited and Lynx Canada Exploration Ltd. worked in the region but very limited assessment has been filed with the government.
For more details the author refers the reader to Table 1, taken from a report by D. Fisher dated January 1980 which reviews exploration in the Grenville Province.
The showings were studied using geochezai.cal sampling, (streams and soils), geophysics (mag. and H.E.M.). Drilling,of course,took place on the main showings. (See Annex 6: Compilation of previous work).
5.0 GEOLOGY
The project area is situated in the west central portion of the Central Metasedimentary Belt (Wynne-Edwards, 1969) of Paleo-Helikian age in the Grenville Tectonic Province. This metasedimentary belt, also known as the Mont Laurier Basin is predominantly underlain by structurally complex marbles, cale-silicate rocks, quartzites and aluminous paragneisses of the Grenville Supergroup. These sediments are underlain by an Archean basement complex consisting mainly of•granitic and migmatitic gn-eisses. Younger intrusions, of anorthositic, charnockitic, syenitic and granitic composition cross cut the supercrustal rocks at various localities. (See Annex 5: Geology Map).
High grade metamorphism characterizes this region. Middle and upperamphibolite facies prevail in the immediate study area.
At least two major periods of folding have been recognized: one of north-south direction and a second of north-east direction. The extent of deformation is obviously severe and the distribution (behavior) of the various units, particularly on the local scale, is very much a function of the composition i.e. competence of the associated rock types. Indeed, this is most apparent when comparing the deformation styles of the incompetent, plastically folded marbles adjacent to the more competent (+ brittle) quartzites and/or quartz-feldspathic paragneisses.
M. Gauthier's examination of the known zinc occurrences led him to recognize two significant associations common to all of the zinc showings namely that a) dolomitic and not calcitic marble is very closely associated with the zinc mineralization, and that b) the transition from chemical sediments i.e. marbles, to clastic sediments i.e. quartzites and/or metapelites, represents a strategic site for potential zinc mineralization. Mineralogically this is reflected by the presence of diopside and forsterite very close to zinc mineralization. Diopside is thought to derive e tamorphically from quartz and dolomite. Zinc mineralization is not found within pure quartzite nor within pure marble but rather in marble containing a substantial amount of calc-silicate minerals. Thus, it is concluded that the original site for zinc mineralization was a dolomite-quartz rock (transitional sediment).

Gauthier also reports having recognized two stratigraphic horizons of marbles: one occurring between the quartzo-feldspathic paragneisses and the rusty paragneisses and the second, stratigraphically overlying the rusty paragneisses. The first horizon is dolomitic and contains all of the known zinc occurrences while the latter is calcitic and contains no known mineralization.
On the basis of these findings, the majority of Shell's field work was concentrated in areas of reported dolomitic and calc-silicate rocks. Rapid field discrimination of dolomitic and calcitic marbles was obtained by the use of hydrochloric acid. Any subsequent recognition of calc-silicate rocks (olivine, diop^ide rich units) in association with dolomitic marbles would thus be regarded as an area of potential zinc mineralization worthy of fu>: ther investigation.
The Principal Lithologies encountered during the 3980 Field Work include:
5.1 CALC-SILICATE UNITS
5.1.1 Ouartz-diopside-tremolite rock: hard, medium to coarse grained rock. Prior to metamorphism, this rock probably contained considerably more quartz than dolomite.
5.1.2 White pyroxenite
White to Light green, medium to coarse grained rock composed almost exclusively of diopside. Color and hardness distinguish it from the marbles. It is thought to represent a metamorphic product of a rock originally composed of about 50% dolomite and 50% quartz. This unit often occurs very proximal to massive sphalerite mineralization. In fact, when the pyroxenite is associated with mineralization, it invariably contains disseminated sphalerite.
5.1.3 Calcitic marble with >30% quartz
A calcitic marble with an appreciable amount of quartz contains in fact calcium and silic, making it a calc-silicate rock. This rock does not contain diopside, forsterite or tremolite because the original rock did not contain dolomite.
5.2 MARBLES Marbles form a very distinctive unit. They are white, coarse grained and soft. Graphite and phiogopite are the accessory minerals. With weathering, they become black. Dolomitic marbles are somewhat darker than calcitic marbles.
5.2.1 Calcitic marble
The dominant type of marble is the calcitic marble. It can contain up to 10% graphite-phiogopite as flakes homogeneously distributed in the matrix which often contains traces of pyrite. This rock effervesces strongly to dilute.HCI. 5.2.2 Diopside-Forsterite rich calcitic marbles
The calcitic marbles can contain appreciable amounts of diopside and forsterite In fact 30% or mare of calc-silicate minerals in the calcitic marble makes it a distinct unit. This unit is important because of its close association with massive sphalerite in all the showings.
5.2.3 Dolomitic marble
This marble is undistinguishable from the calcitic marble other than by its very weak or non-effervescence with dilute HCl. This unit is usually iron sulphide free. Dolomite can be observed as individual grains in a calcitic marble or as 100% dolomitic beds. In both cases (grains and beds) the dolomitic portion is in positive relief (greater hardness) compared to the calcitic marble.
5.3 Rusty Paragneisses
The rusty paragneisses include an entire group of clastic metasediments containing a relatively strong percentage of graphite and iron sulfides. Quartz, biotite, hornblende, plagioclase, calcite and dolomite are the principal minerals. Depending on the main fraction,it will be a biotite-hornblende paragneiss or a quartzite etc. The granulomeiiry varies from medium to coarse.
5.4 Amphibolite
This is a hornblende rich rock with quartz and biotite. It is medium to coarse grained and is dark green. The amphibolite occurs as isolated fragments within the marbles, or as relatively thick formations(sills?).
5.5 Geology of the showings
Provided in a back pocket of this report, are the geological maps of the Lafontaine Leitch and Parker zones. Mapping of these zinc occurrences confirmed that dolomite is associated with every mineralized zone. Also, it is true that diopside-forsterite rich marbles occur with the mineralization. White pyroxenite was found only in the immediate vicinity of the ' mineralization,
6.0 Geophysical. Surveys
A Questor Input survey was flown over a 280sq. km surface area in late April 1980. The survey, which generated 1500 line-km of flying (200 it spacing) was flown in two directions: a rorth-west direction for the southern one third of the area and an east-west direction for the remainder in accordance with the general trend of the formations. 9
Aeromagnetic data enabled the tracing of the biotite paragneiss units acrosa the entire map area. A better definition of the iron formation in the Lake Roddick area was also obtained with the aermagnetics. Numerous A.E.M. anomalies were detected from this survey, a number of which are formational in appearance and apparently associated with some of the rusty paragneisses. Other anomalies, on the other hand, present short isolated characteristics, some of which occur within the favorable dolomitic marble units.
Not surprisingly, no Input responses were obtained over the Bouchette and Leitch* showings where, in the case of the latter, mineralization consists exclusively of massive sphalerite. Culture interference (nearby transmission line) unfortunately hampered an unambiguous interpretation of the Input data over the Lafontaine* deposit where known ircn sulphide mineralization (gossan) associated with the sphalerite ore, is conductive in hand specimens.
Preliminary results from test V.L.F. (E.M -16) surveys (readings at 25m spacing on lines 50m or 100 m apart) over Lafontaine, Leitch and Parker were spotty indicating definite but weak one-line anomalies. More detailed surveys would be needed to fully evaluate the effectiveness of this technique. Results of these surveys are presented on the compilation map of each zinc occurrence at the back of this report.
* Annexes 7,8,9,10, & 11 are geology and compilation maps for Lafontaine Leitch, and Parker zones.
7.0 Geochemical Suiveys
Orientation soil, stream sediment and rock sampling was carried out over the Lafontaine, Parker and Leitch zones. Ph determinations in soils and streams were simultaneously made bat, little if any variations were detected. In fact, Ph values remained fairly coestant at 6.3 in soils and 6.8 in streams water. It is possible the Alkacd Ph Kits(Litmus Paper) used in these tests was not sufficiently sensitive to respond to lithological variations as was hoped.
7.1 Soil Surveys
The object of these surveys was to determine which elements and which specific horizon(s) would respond best to the zinc mineralization. Thns, horizons A,B and C were sampled (organic layer, leached layer, unleached layer) and analysed for the following elements: Cu, Ph,.Zn, Cd, Mn, Ba, Ag, Hg, as recommended by Richard Cote.
The samples were taken twenty-five (25) meters apart on lines perpendicular to the stratigraphy and the showings. Depending on the size of the showing the lines themselves were 50 or 100 meters apart (50 m at Leitch and Parker and 100 m at Lafontaine). Samples were collected after digging a hole with a shovel to expose the soil profile. The samples were out into paper bags, identified, dried and sent to the Chimitec Ltee. Laboratory in Ste-Foy, Quebec.
Profiles were drawn for each element and for each line sampled on the showings. A total of 114 samples were taken (63 at Lafontaine on 4 lines, 18 at Parker on 2 lines and 33 at Leitch on 3 lines). Only infrequently were specific horizons at certain. sample sites not obtainable.
Figure 3 shows a typical response of the soil over a showing, and Tables 2-3-4 give some data on each element in the soils around the showings.
Not all the soil profiles are included in this report but from the data the following can be included:
- A Horizon gives a very g00%: response and has the advantage of being almost always available. Its disadvantage: more easily contaminated.
-B Horizon gives a very good response also, is less subject to contamination but is not always well defined in the soil.
-C Horizon gives poor response and therefore should not be considered further in future surveys.
-Zn, Cd and Hç are the best elements to locate the showing. They give high peaks very close to the mineralisation.
-Cu, Pb and Mn give a medium response and are not constant.
-Ba and Ag are very erratic: Should eliminates.
It is also felt that twenty-five (25) peters is the minimum .spacing to be used on the lines for a reconnaissan^e survey. Distance between lines should be approximately one hundred (100) meters.
The data for this work have been statistically treated by Data Plotting Services Incorporated. The mean, standard deviation, variance and histograms can be seen in Tables 2,3 and 4.
From the above it is recommended that in future reconnaissance surveys, for this type of mineralization, that A and B horizons be collected every twenty-five (25) meters on parallel lines no greater than one hundred (100) meters apart. The samples should be analysed for Zn, Pb at least and possibly Cd and Mn the latter which might provide some information on possible contamination effects.
It is felt that lead should be included in the determinations not because of the response it gave in these surveys, but because the mineralization sought, might contain lead such as is found at New Calumet.
N.B. Contour maps for Leitch and Lafontaine of zinc in B horizon are included in back pocket (see compilation maps).

The stream adjacent to the Leitch showing was not sampled for it is reported to have provided a good zinc anomaly from Cominco's earlier work. Samples were analysed for Cu,Pb,Zn,Cd,Hg,Ba,Ag and Mn. At Lafontaine, the closest streams to the deposit were sampled and a few away from the deposit to determine background values. It was found that twi of the three highest zinc values were the closest to the mineralization. The other high value has associatea very high values in Cu,Pb,Ag,Ba and particularly Mn. It is felt that, here, Zn co-precipitated along with the other metals in what is probably an organic rich sample as is suggested by the high manganese oxide content. (For detailed results see Annex 1) In future campaigns, therefore, Zn and Mn should be the elements analysed. To these can be added Pb and Cd to mcnitor more closely the effects of the Mn content. We should also note any sample that obviously contains organic matter. 7.3 Geochemical Rock Surveys A total of fifty-seven (57) samples on the three showings (Lafontaine (33), Letich (18), Parker (6)) were collected. Two sections crossing the stratigraphy and the mineralization at Lafontaine and one at Parker wire completed. The Leitch zone being structurally more complicated could rot warrant systematic sampling. In all cases mineralized zones, hangi^^ walls and foot walls were sampled. In addition, all other rock types were ,alapled: rusty paragneisses, dolomitic and calcitic marbles, calc- silicated rocks and amphibolites. Analyses for major and minor elements including Cu, Pb, Zn, Ag, Ba, Cd, Fe, Hg were made. All analyses were done by X-rays laboratories in Toronto. The complete results are included in Annex 3. From this data the following observations can be made: The only values of cadmium detected are directly associated with zinc mineralization. - Mercury gives a good response for the mineralization but not as good as Cadmium - The walls of the mineralization, which usuallÿ consist of calcitic marble with diopside - forsterite- pyrite - pyrrhotite, have a much higher content in zinc than the other calcitic r..arbles or any other rock type. For example, at Lafontaine, the walls contain an average of 1120 PPM in Zn compared with the 30 PPM average for the other calcitic marbles. The same phenomena can be observed at Leitch. - The white pyroxenite and dolomitic marbles which are supposed to host disseminated sphalerite near a zinc occurrence (M. Gauthier 1978) have respectively 2820 and 650 PPM in Zn. These values are well over the 16 (3\ 31 J/4 W \LA2 R , ~ - L.

LTD STREAM SAMPLING AROUND LAFONTAINE PROSPECT (,#) C F oafflaI 2 3lCm L~ J SCALE 1:50000 17 40 PPM average contained in the other rock types. These values are from Lafontaine. - All the lead detected at Lafontaine is in samples coming from the mineralization and immediate foot and hanging walls. - The zinc content in :he mineralization at Lafontaine seems to decrease from east to west. - The zinc content of the rusty paragneisses increased to 200 PPM in one case, although the average content was 50 PPM. One magnetite sample returned a value of 400 ppm zinc. It is apparent from these surveys that In, Cd, Hg, Pb, and Cu are the elements which sould be analysed for in rock samples. Also, any calcitic marble containing pyrite and diopside, even if sphalerite is not visible, should be analysed for its minor elements. White pyroxenites and any mineralized dolomites should also be systematically analysed. 8.0 CONCLUSIONS The orientation surveys over the known zinc occurrences have provided Shell with many answers to the questions regarding the applicability of certain exploration techniques in looking for Balmat-Edwards type of zinc mineralization in the geologically complex terrains of the Grenville Province. The geological mapping and interpretation presented by Michel Gauthier appears to have been largely confirmed during Shell's initial field investigation. However, due to the rapid lithological changes even on the local scale (possibly largely due to the tectonic complexity of this region) extreme care should be taken in attempting to select or evaluate large areas on the basis of cursory mapping. Geochemical soil surveys A & B horizons, appear effective in defining near surface zinc mineralization although anamolies are typically very punctual. The 25 meter sampling interval is probably adequate for reconnaissance work but should at least be reduced by half for more detailed surveys. Geochemical stream sediment surveys also seem to be a valid reconnaissance exploration technique in this area where clays are largely restricted to the river valleys. A 500 m spacing for initial surveys is probably adequate although 100m spacing would likely be required for any follow-up, more detailed survey. 18 Minor element (metals) determination in rock samples appears particularly valid with respect to the favorable or potential host lithological units which include all dolomitic marbles, diopside, forsterite, pyrite rich calcitic marbles, calc-silicate units and white pyroxenite. It is important to note that the geochemical halos are, however, very restricted to perhaps within only 1 meter of massive sphalerite mineralization as is seen at Lafontaine and Parker. Finally, it is apparent that a certain type of zinc mineralization such as the Lafontaine deposit which hosts appreciable amounts of iron sulphides (Py Po) would likely produce E.M. responses and that the Input system could be capable of detecting such mineralization. Whether follow- up to some of these airborne responses will lead Shell 'directly or indirectly to (economic) zinc mineralization has yet to be tested. However, initial reconniassance work, as described in the following section, is promising. ; I Men% 161,331 triardningnanMillakkb,a 4 12, IN' 19 1. 0 IL1TRO0UCTI ON This section presents the results of the 1980 field investigation of the fourteen selected airborne anomalies. The selection, based on best geophysical parameters and promising geological environment, was made by J. Castonguay, A. Tremblay, D. McAuslan and P. Lortie in mid July 1980. Fieldwork consisted of reconnaissance mapping along with soil sampling (B horizon only) and V.L.F. profiling. Minor element analyses were also made on all bedrock exposed in the vicinity of the conductors. Soil and/or bedrocking sampling was not feasible on all of the selected targets. The diagrams which follow present in this order: location, 'local geology, V.L.F. data and soil profiles for Zn, Pb and Cd for each anomaly. The reader is referred to section I for the regional geologic setting. For convenience, a brief summary of the above data is provided for each anomaly. References to recommendations for additional geophysical work implies in this report, H.E.M. and magnetometer surveys. It is conceivable however, that test spectral I.P., conventional I.P. or gravity may be warranted in future investigations. 2.0 LOCATION The reader is referred to figures 5,6,7,8,9,10 and 11 which indicate the location, Input responses and recon grid lines for the group of anomalies visited in the field which include anomalies A to N.

Of interest, however, was the presence of two outcrops of diopside bearing calcitic marbles. The Input signals were located on the grid by the VLF survey. Another conductor just south of the previous conductor was also detected. Unfortunately, no zinc anomaly was detected in the soil and only traces of pyrite were identified in bedrock. On the basis of these findings, no further work is recommended in this area.

No dolomite, cal:-silicate rocks, on diopside marbles were identified. The VLF conductor is strong and corresponds exactly with the Input responses which have associated magnetics. A sample of rùsty paragneiss (#2605) was shown to contain 200 PPM zinc. This corresponds very closely with the values in the soils. Sample 2606 is magnetite mineralization from an old nearby trench. The presence of magnetite most likely accounts for the aeromagnetic anomaly while graphite/magnetite mineralization as found in the old trenches may explain the A.E.M. anomalies. The weak zinc values in the soil appear to correspond to bedrock values suggesting no significant bedrock zinc mineralization is present over the immediate grid area. No further work is recommended in this area.

Dolomitic marble is a major rock type in this area. Diopside-forsterite rich calcitic marbles outcrop at several localities and a large outcrop of white pyroxenite was identified at the eastern limit of the base line on the reconnaissance grid. A thin section of the pyroxenite shows this unit to be compared almost exclusively of medium grained equigranular diopside. V.L.F. profits were inconclusive but soil geochemistry proved quite encouraging. In fact, first order anomalies were obtained for Zn, Pb and Cd at one locality. This area definitely warrants follow-up work including more detailed soil sampling and mapping along with ground magnetometer and H.E.M. surveys.

Some bands of rusty paragneisses are interbedded within the marbles. One such band, in the centre of the grid area, was sampled and found to contain very little zinc. The VLF conductor coincides well with the rusty paragneiss, which also appears to coincide with two of the Input responses. The geochemical survey showed one very strong zinc value: sample E-38-S contains 4800 PPM. This is the highest zinc content of any sample collected from the soil surveys over the airborne anomalies. On the other hand, the zinc profiles indicate the background values for zinc are somewhat erratic. Detailed soil geochemistry is, therefore, needed to better define the zinc distribution in the overburden. Also, detailed mapping along with ground geophysical surveys (mag. and H.E.M.) should be completed over this A.E.M. anomaly.

Calcitic marbles with diopside and pyrite outcrop at many localities. The calcitic marble may be very rusty. Dolomitic marbles were not identified . A pyrrhotite bearing quartzite was found on L2+00SW. Pyrrhotite may be responsible in part for the strong magnetic anomaly associated with the A.E.M. conductor. A very weak VLF conductor appears to coincide with the Input responses. The available information suggests the conductor may occur within the marble units however, the soil geochemistry does not indicate any significant values in zinc. Rock sample 2612 reveals 110 PPM zinc in the quartzite. It is probable this quartzite is the cause of the weak peaks obtained in the soil profile for zinc. On the basis of this information it does not appear this conductor warrants further investigation at this time.

Rusty paragneisses outcrops abound in the grid area while calcitic marbles occur on the eastern and western extremeties. A strong VLF conductor was detected in the centre of the grid which grossly corresponds to the Input signal which has an associated medium magnetic anomaly. A small outcrop of rusty paragneiss with pyrite and graphite occurs near the Input anomaly. Geochemistry is indeed the reason why follow-up work is recommended on this anomaly. A very strong zinc (Pb &.Cd) anomaly was detected in the soils proximal to the Input response (see Figures 51,52, 53, 54 & 55). The geochemical data collected in the initial 1980 'survey suggests the rusty paragneiss units do not contain more than about 200 PPM zinc. Whether this particular area proves different has yet to be determined. Detailed mapping, geochemistry and geophysics will hopefully provide more information on the probable cause of this conductor and geochemical anomaly.

A dolomitic marble was found in the north-east part of the grid. In the central part of the grid a band of rusty biotite paragneiss with iron sulfides was identified. Rock sample 2617 is from this unit. Rock sample 2616 is a calcitic marble with some sulfides. Both show:.weak values in zinc. A boulder with sphalerite in it was found on L24-00S, at the east extremity. The rock analysis of this sample (2615) confirmed the presence of sphalerite in the boulder with 680 PPM zinc. The VLF survey localized one relatively strong conductor and another weak one. The strongest cdrresponds with the rusty biotite paragneiss. The Input responses are situated on either side of the VLF conductors. The geochemical profiles show two 3rd order anomalies in zinc and a first order anomaly in lead. Considering the presence of a boulder with sphalerite, the proximity with the Bouchette zone and the anomalies in the soils it is recommended that detailed mapping as well as detailed geochemistry and geophysics be completed over this area.

Dolomites and calc-silicate rocks cccur in the central portion of both lines. Elsewhere rusty paragneisses and pegmatite are found. The rock samples (2618, 2619) are mineralized (Py) dolomite and calcitic marbles. They did not contain any zinc, however. The VLF survey depicts one strong and one weak conductor with which a medium magnetic anomaly is associated. Geochemistry indicates two 3rd order anomaly in lead. No anomaly in zinc was detected. Considering the relatively good geology, it is suggested that geophysical surveys be completed over what looks to be a very good conductor.

The anomaly consists of two three channel Input signals with an associated weak to medium magnetic anomaly. The regional aeromagnetic survey sees to indicate this zone is related to the Bouchette zone. It is for this specific reason that this anomaly was selected. Geophysical surveys are recommended over this anomaly. Visited by Jean Castonguay Georges Dagenais 3.12 Group L The L anomaly consists of a group of eight(8) Input responses that cover quite a large area. Only one outcrop was located: dolometic and calcitic marbles with minor feldspar-biotite paragneisses. Clay overburden extends over almost all of the area. Consequently, no geological or geochemical maps were produced. A few stream samples were taken. These are identified on the location map. The analysis showed a very constant 35 PPM zinc in all samples. The lack of information and the low values of zinc in streams places this area on a low priority at the present time:. Visited by Jean Castonguay Georges Dagenais 3.13 Group M The geology of this anomaly consists mainly of calcitic marbles with layers of rusty paragneisses (quartz-feldspathic ones). Interestingly, tremolite and white pyroxenite (in minor quantity) were identified in the south-western part of this area. Significant amounts of graphite were recognized in a few places and it is suspected this mineralization may be the cause of some of the Input responses. Clays and swamps cover large portions of this area so that soil geochemical profiles could not be obtained. The white pyroxenite will be sampled in 1981 to test for the presence of zinc. Should the analyses prove uninteresting, no further work would be reccr'r'ended in this area.

Sulfides in trace amounts were found in a dolomitic marble (rock samples no. 2622), but analyses showed this to be pyrite. No explanation was obtained for the Input responses from initial field investigation. Geochemical profiles for the zinc show an interesting 2nd order anomaly and a third order anomaly. A first order anomaly in lead on Line 2+OON can be noted. Due principally to the favorable results of the geo- chemistry, it i- recommended that detailed mapping, geochemical sampling and geophysics be carried out in this area in 1981.

Of the numerous airborne anomalies examined during the 1980 field season, several were eliminated on the basis of graphite and/or pyrrhotite mineralization although the majority remain unexplained to date. For a complete summary of the anomalies and the recommendations please refer to the following Table 6. The anomalies on which more work is recommended are: groups C, D, E, H, I, J, K and N. These anomalies should be staked or acquired through negotiation as soon as possible. Groups 0, P, Q, R, and S should also be staked because of their interest on the basis of available geophysical and geological data. The mineralogical/ stratigraphic criteria presented by M. Gauthier with respect to the zinc mineralization appears to be largely correct as established from Shell's first field season work. It appears likely, therefore, that the geological context will be the important guiding factor in selecting future areas for exploration of this kind. In a mature exploration area such as the Maniwaki region of the Mont Laurier Basin where exploration companies such as St. Joe's, Cominco,Uranetz, Inco, Lynx-Canada and Beth Canada have explored for Pb-zinc deposits within the last ten years (particularly), it was decided Shell should establish its own exploration approach based on as innovative an exploration technique as possible to improve the chances of discovery. The choice of an airborne E. M. system reflects, in part, this innovative approach - a method not tested by others. The recommendations presented on the following pages will hopefully lead to a more thorough evaluation of the economic potential of this area. Furthermore, it is expected that any encouraging results derived from the various orientation surveys will provide the necessary incentive in applying these techniques (new or old) to other, less explored portions of the Mont Laurier Basin. k J GEOLOGY GEOPHYSICS ANOMALY GEOCHEMISTRY TOWNSHIP I NERALI- ♦ INPUT REMARKS — RECOMMENDATIONS VLF AEROMAG.

Detailed mapping and geochemical surveys should be completed where possible while ground geophysical surveys (mag. & H.E.M.) should be completed on same as well as on those properties with thick clay/sand overburden situations. Orientation overburden drilling would be considered also in the latter cases. While this detailed work is being carried out, it is proposed that other promising areas ie, north, south and east of the present study area, be examined on a reconnaissance level in 1981 to define other favorable areas over which detailed exploration programs could be planned. Should the time permit, other reconnaissance work could involve the follow-up work recommended by J. Castonguay in 1977 for similar Pb-Zn mineralization in the eastern portions of the Grenville Province. Because graphite is present in so many of the lithological units, a discriminating tool, such as Spectral I.P. or even gravity (might also be effective for detecting massive non conductive sphalerite) may be techniques worthy of serious consideration when attempting to screen numerous airborne anomalies.
