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.
