Location

This claim group is situated on the south side of Opapimiskan Lake at latitude 52 0 37' and longitude 900 22'.

Previous Work

Kenpat Mines Limited held this gold prospect during the early 1960's. At that time a UOO foot grid was cut over the greatest part of the above numbered claims. A magnetometer survey was conducted over the grid with station intervals of 100 feet. Extensive trenching was done and several drill holes were cored in iron formation.

See "Kenpat Mines Limited" - O.D.M. assessment work files,Red Lake, Ontario.

In 1973 the property was restaked "by A.L. and W. H. Musselwhite. Geological napping was done followed by a considerable amount of gold panning in soil covered sections which outlined several anomalous high gold areas. One of these high gold anomalies was cross-sectioned by diamond drilling and a mineralized gold bearing zone was intersected in iron formation. The sulphide-oxide-arsenide mineralization intersected in this drilling appeared to be sufficiently concentrated to cause a ground S.M. conductor, therefore, limited E.M. work was done by Canadian Nickel Company, or. behalf of the Musselwhite Syndicate, in June of 1975 in an effort to prove continuity to the zone of interest.

Object of Surveys

The main purpose of the magnetic survey was to outline the magnetite rich iron formation and also to locate sulphide concentrations with high pyrrhotite content in areas covered by overburden.

The electromagnetic survey was done to outline ground conductors that might represent heavily mineralized sulphide zones which could be either magnetic ornon magnetic.

Magmetometer Survey (Procedure)

The instruments used are Sharpe MF-1 fluxgate magnetometers which measure the vertical component of the earth's magnetic field directly in gammas, positive or negative, over a range of 100,000 gammas. These hand held magnetometers require no orientation and after coarse levelling the magnetic reading is recorded from a meter mounted on top of the instrument.

In order to establish a network of reliable base stations the following procedure was used: Starting from 00-30S all the 00 base line stations at the grid line intersections were read twice, first going southward to 00-603 and again when returning northward to the starting point. These readings were then drift corrected to a background magnetic reading at 00-32S and the average of each set of readings was plotted.

The above procedure was repeated for establishing magnetic reference stations along the 20E control line from 20S to 60S and again all readings were made relative to the base station at 00-32S.

During this survey most of the magnetic readings were recorded in the 10,000 gamma instrument range, however, all ranges both positive and negative had to be used during the course of the survey.

Diurnal corrections were made to the pre-established base station readings thereby making all magnetic readings relative to the magnetic background readingtaken at- 00-323.

Electromagnetic Survey (Procedure)

The equipment used is INCO designed and known as Mark III and Mark IV ground E.M. units. Both units operate at 1000 C.P.S. and are battery powered.

The Mark III utilizes a large transmitter coil suspended in the vertical plane by an aluminum East then formed into a triangular shape by placing a 15 foot aluEiinum spreader bar horizontally across the base of this coil.

The Mark IV transmitter is a small, circular, hand held coil which is operated in the vertical plane.

The receiving equipment is identical for both of the above transmitters; it consists of a snail circular coil with detachable earphones. This coil is held in the horizontal plane while reading and it measures the dip of the total magnetic field through a process of null detection.

The survey procedure used is commonly called the "FAN" method. The transmitter remains at a fixed location while hOO foot grid lines are read across the geologic strike, usually on both sides of the transmitter setup. Readings are taken when the receiver is positioned along strike from the transmitter and this is generally attained by shouting back and forth and then pointing the transmitter coil at the receiver. Any conductor within range of the transmitter produces a

- 3 -

secondary electromagnetic field distorting the primary field. TYiis distortion is measured in terms of dip angles, in degrees, on a clinometer attached to the receiving coil. These angle readings indicate the direction of the source of the secondary field and a zero reading at the cross-over represents the axis of the conductor'.

Survey Data^

Working from-a tent camp on the south shore of Opapimiskan Lake two Canadian Nickel Company employees were involved in'all phases of the survey work including '- cutting of new grid lines and the re-cutting arid re-chaining of old grid lines. . Both of the I-Iusselwhite brothers were also involved in .line cutting and chaining.

Dates when work vas performed by Canico employees are:

Grid lines are spaced mainly at ^00 foot intervals, however, in complex magnetic^ areas, or in areas containing multiple short, conductors, it was necessary to cut and chain 200 fcot spaced grid lines to help define the" anomalous picture.'' Chainage pickets are 100 feet apart along the grid lines. Magnetic readings were take.i at 50 foot station intervals while 100 foot electromagnetic stations were read. . .

^An accompanying plan shows the contoured results of the magnetic survey,^

on a scale of l" s 200 feet. Magnetic readings are plotted in gamma values ".V^T'../' relative to an arbitrary base station of 5300 gammas located at 00-3PS.

The general area covered by this survey is intensely and erratically magnetic. Spotted anomalies range from +105JOOO gammas to -86,000 gammas. The eastern half of the claim group contains the most -uniform and continuous magnetic anomalies which are undoubtedly caused by bands of magnetite rich iron formation. The more important magnetic anomalies are briefly described as follows:

Two very strong, parallel, linear magnetic zones strike northwestward from the southeast corner of the grid, through claims Pa 3697^9, 3697^6, 3697H5, 369766, 369765, entering Opapimiskan Lake in claims 36976!* and 369771.

A prominent folded magnetic zone was delineated in the central part of the survey area. The east flank of this structure seems to originate in the southeast corner of claim Pa 369765, strikes southeastward through claim 3697^5, southward into 3697^8 then folds and strikes northwestward through claim 3697^7, to terminate in the south half of claim 3697** 1*.

The west half of the survey area consists mostly of short, strong, erratic anomalies, however several broad weak negative zones were outlined.

Claims Pa 369755 and 369757 do contain several small positive linear anomalies which are aligned with the regional strike direction.

Electromagnetic Survey Results

E.M. results are also shown on an accompanying plan on a scale of l" ^ 200 feet. Readings are plotted as left or right {L or R) and the number following denotes the size of the angle in degrees.

Parallel ground electromagnetic conductors are common within the surveyed area and are generally spaced about 300 to 500 feet apart.

In the east half of the area two strong, parallel conductors extend from the southeast corner of the grid in claims Pa 3697^*9, 3697^6 through 3697)45, 369766 into 369765 where there appears to be a break or offset. Two nearby strong conductors in claia 369771 continue along the same northwestward strike direction into Opapimiskan Lake.

The most outstanding conductor is a long strong folded zone located near the center of the survey area, conforming with the folded magnetic anomaly pre viously described. The western part of this conductor begins in the southeast corner of claim 369753 then strikes southeastward through 3697^1*, 36971*7, halfway through 3697^8, where it folds and begins striking northwestward through 3697^5 into 369765. Here the conductor weakens noticeably and probably does not connect with another nediua-strong conductor, part of which lies directly on Strike.

A cluster of three medium-strong conductors occur between major magnetic anomalies in the southwest corner of claim 369765 and the southeast corner of claim 36976^. All three of these conductors enter Opapimiskan Lake. A medium strength conductor in the southwest part of claim 369771 is situated on the east flank of a major magnetic anomaly.

- 5 -

The west half of the grid contains a number of discontinuous conductors varying from weak to strong. The longest conductive zone enters Opapimiskan on the northwest side of the grid and strikes southeastward through claims Pa 369753, 369T55 deep into claim 3697^7. A parallel medium-strong conductor occurs on the east side of the long zone Just described. This conductor strikes southeastward through 3697^7 into 3697148 where it runs off the south end of the grid.

Other medium-strong conductors with various strike lengths occur in claips 369750, 369755, 369756 and 369757. Two of these conductors are strong where they run off the south side of the grid.

Several short weak conductors are scattered about the work area but these are not considered important.

Conclusions

The magnetometer survey was quite effective in outlining the banded iron formation.

In general the magnetic anomalies definitely correlate with strong sections of the E.M. conductors, however, this is not saying that the conductors are due to magnetite. Within a strong magnetic anomaly at ^US-17E the conductor proved to be caused by sulphides in iron formation seen in mineralized rock exposures and intersected at depth by drilling.

Recommendations

Diamond drilling is recommended to test all conductors where gold panning has indicated anomalous gold values.
