INTRODUCTION

This report outlines the results of ground geophysical sur

veys completed on Tully A-ll, 12, 13.

l. LOCATION

The property consists of 8 contiguous unpatented mining

claims straddling the Buskegau River in the southwest

portion of the township. The claims are numbered P512687

to P512694 inclusive and occupy the N 1/2 of Concession 11

Lots 8 and 9 of Tully township (see Figure 1).

2. ACCESS

Access to the west side of the property is afforded via

a bush road which extends from Feldman Lake on highway

665 north of Timmins northeastward into the southwest

corner of Tully township. A network of old logging

roads facilitates access to various portions of the

grid.

3. LINE CUTTING

An east-west baseline was established on the property ex

tending 1.6 km west from a point 400m south of Lot 7-8,

Con.11. Crosslines were cut at 125m intervals. The

baseline and all crosslines were chained and picketed at

25m intervals. A total of approximately 14 km of line

was cut, chained and picketed.

4. TOPOGRAPHY

The property is covered mainly by black spruce and al

der. There is no appreciable relief.

5. GEOPHYSICAL SURVEYS

5.1 Electromagnetic Survey

Electromagnetic surveying was carried out with

a MaxMin II E.M. unit. A 200m cable was used

for routine coverage at operating frequencies of

444 Hz and 1777 Hz. Technical and operational

details of the MaxMin II are presented in Appen

dix I.

The results of the E.M. surveying are shown in

the prints accompanying this report. Map I pre

sents the low frequency data and Map 2 the high

frequency results.

Two east-west striking, conductors ("A" and "B"),

were located; "A" extends from line 1625W to line

1250W in the north portion of claim P512687. A

second, discontinuous zone, "B", is present on claim

P512692-693. Both conductors dip approximately

vertically and are indicated to lie beneath 60m to

90m of glacial overburden. Inphase to quadrature

ratios at 444 Hz indicate moderate conductivity.

There is no direct magnetic correlation with either

conductor.

The indefinite conductive response on Conductor "B"

at 1777 Hz on line 750E was subsequently checked with

a 250m cable. The presence of a bonafide bedrock con

ductor was verified.

Electromagnetic readings on the grid were often ex

tremely noisy due to highly conductive overburden

conditions.

5.2 Magnetic Survey

A Geometrics G-816 proton precession magnetometer was

employed for the magnetic survey. Correction for diur

nal variation was made using a Geometrics Barringer Re

search BM-123 base station magnetometer. Details of

the magnetic method and technical specifications of

the instruments employed are presented in Appendix I.

The magnetic pattern is dominated by an approxi

mately 500 gammas magnetic high centred on claim

P512692 (Map 3).

Magnetic gradients indicate a steeply dipping body

beneath a substantial overburden cover. The north-

south magnetic trends in the area of lines 750W to

1375W are a reflection of the above anomaly. These

do not reflect bedrock strikes which are indicated

to be approximately east-west considering the E.M.

results.

The magnetic high appears to be truncated to the

west, in the area of line 750W, possibly by a

north-south fault.

6. CONCLUSIONS AND RECOMMENDATIONS

Conductors "A" and "B" are probably due to graphitic

units, possibly with some associated sulphides. The

magnetic anomaly appears to represent an ultrabasic

intrusive. Neither conductor appears to have been

drilled although an attempt was made to drill Conduc

tor "A" by Questmont Mines Ltd. in 1974. The hole

was abandoned due to drilling problems before the

conductor was intersected.

tBoth conductors should be drill tested as follows:

Conductor Collar Dip Azimuth Length

A 1375W, 250N -6QO 360O 170m

B 750W, 137.5N -50O 180O 220m

Consideration should be given to testing the magnetic

anomaly on line 625W at 75S in a 200m hole drilled grid

south (ISO0 ) at -550 .

Further work will be contingent on the results of the

above.
