Dear Mr. Harquail:
Submitted herewith is our report entitled:
GRID K
MAGNETOMETER AND ELECTROMAGNETIC SURVEYSWILKIE TOWNSHIP
DISTRICT OF COCHRANE LARDER LAKE MINING DIVISION
ONTARIO
The ground geophysical surveys extended and further defined the regional geology as mapped by the Ontario Division of Mines.
A northwesterly trending fault zone was mapped in the western portion of the survey area, the relative position and sense of which adds supportive evidence to the right-hand displace ment indicated along the Black River Fault zone mapped on Grid J, located in Walker Township.
The magnetometer survey also identified two diabase dikes and a large metamorphosed mafic intrusive body mapped along the southern property boundary. It is felt that this intrusive body either lies along the northern contact of or is synonymous with the Pipestone Fault zone.
The electromagnetic survey mapped a near surface bedrock conductor, C-l, located in the southeast corner of the survey area exhibiting a conductivity thickness of 10 mhos. This conductor is believed to be the mappable expression of a finely disseminated

sulfide band associated with a tuffaceous horizon lying within the metavolcanics.
In light of the proven structural significance of the Pipestone Fault System as a known channel way for gold bearing mineralizing solutions, it is strongly recommended that the structural relationship between the metamorphosed mafic intrusive body and the Pipestone Fault zone be determined. It is also recommended that additional ground geophysics be carried out in the vicinity of Conductor C-l. This additional work would consist of several selected I.P. profiles carred out across the inferred axis of Conductor C-l.
GENERAL
The following geophysical report details the results
of the ground magnetometer and electromagnetic surveys under
taken by W. G. Wahl Limited on behalf of Surveymin Limited.
The property is situated in the southwest corner of
Wilkie Township, District of Cochrane, and is accessible by a
four-wheel drive vehicle east from the village of Monteith on
concession road II, then south along Lot road 5 to the first
concession road, then east to the Black River, a total distance
of 10.3 km. From this point the property is accessible by
canoe, l km down the Black River and then east upstream l km
on the Shallow River.
The Wilkie Township property consists of the following
sixteen unpatented mining claims, all of which are duly recorded
with Mr. G. J. Koleszar, Mining Recorder, Larder Lake Mining
Division:

LINE CUTTING
The linecutting was conducted under the direct super
vision of Mr. S. Wabananik of Timmins, Ontario, during the
period from March 9, 1980 to April l, 1980. The sarvey grid
consisted of 3.2 kilometres of baseline trending E-W and 25.74
kilometres of grid line trending N-S, established at one hundred
metre intervals along the entire baseline. Thirty metre
stations were established on all lines.
The thirty metre station interval was apparently
established by the line cutting crews using an imperial chain
oh the grid lines with the assumption that 100 feet was equal
to 30 metres.
MAGNETOMETER SURVEY
The magnetometer survey was carried out by R. Harwood
of W. G. Wahl Limited during the period from September 8 to
September 14, 1980, employing a Scintrex MP-2 total field
proton precession magnetometer in conjunction with a Scintrex
MBS-2 total field magnetic base station attached to a Simpson
M2750 strip chart recorder.
The magnetic data was observed at a 15 metre station
interval on all lines of the established grid. The data was
corrected for diurnal fluctuations, reduced to a local datum
and presented as a contoured interpretation of these data.
MAXMIN II HORIZONTAL LOOP ELECTROMAGNETIC SURVEY
The horizontal loop electromagnetic survey was carried
out by J. Palladini of W. G. Wahl Limited during the period
from September 8 to September 14, 1980, employing an Apex Para-
metrics MaxMin II horizontal loop survey unit in the maximum
coupled mode. The inphase and quadrature response parameters
were recorded at 444 Hz and 1777 Hz utilizing a 600 foot coil
separation and a 30 metre station interval. These data are
presented in profile form.
VLF ELECTROMAGNETIC SURVEY
The VLF electromagnetic survey was conducted by R.
Harwood of W. G. Wahl Limited during the period from September
8 to September 14, 1980, employing a Crone Radem VLF EM survey
unit. This unit measured the inclination or dip angle and the
total field strength. The VLF station used was Cutler, Maine,
having a frequency of 17.8 KHz. All observations were taken
facing east at 30 metre stations on the lines of the grid
which were interrupted by open water.
DISCUSSION
The magnetometer survey extended and further defined
the regional geology as mapped by the Ontario Division of Mines
and presented on Map No. 2205.
A major lenticular magnetic expression of up to
2,OOOnT was mapped transecting the survey area trending north
easterly from a point 700 metres south of the baseline on line
HW to the baseline on line 8E at which point the magnetic
anomaly appears to be open to the northeast. This anomaly is
thought to be the mappable expression of a late precambrian
diabase dike, the western-most end of which has been faulted
and structurally offset by a northwesterly trending fault zone.
Movement along this fault zone appears to be a right-hand
displacement and is up to 200 metres.
A younger, early precambrian, diabase dike was also
mapped trending N-S, lying parallel to and coincident with
line 14E. This lenticular magnetic expression is characterized
by a total magnetic field intensity of up to 793nT.
The large regional magnetic feature of up to
16,OOOnT, located in the southeastern portion of the survey
area, is thought to be the mappable expression of a metamor
phosed mafic intrusive body.
The MaxMin II horizontal loop survey identified two
anomalous conductive zones lying within the survey area, both
of which will be discussed in the following section of the
report.
Conductor C-l;
Conductor C-l is located in the southeast corner of
the survey area and is characterized on lines 9E through 12E
inclusive, lying roughly parallel to and 600 metres south of
the baseline. This anomaly is interpreted to be a vertical,
near surface ( <']-5 metres) conductor, up to 4 metres wide,
exhibiting a conductivity thickness of 10 mhos at the low
frequency (444 Hz) response.
Conductor C-2;
Conductor C-2 is located in the west central portion
of the survey area and is characterized on lines 3 and 4W
inclusive, lying roughly parallel to and 480 metres south of
the baseline. This anomaly is interpreted to be a very poor
conductor and is thought to be an overburden response related
to the beaver pond.
CONCLUSIONS
The apparent right-hand displacement interpreted
along the northwesterly trending fault zone mapped in the
western portion of the survey area adds supportive evidence to
the right-hand displacement indicated along the Black River
Fault zone mapped on Grid J, located in Walker Township.
The metamorphosed mafic intrusive body mapped in the
southeastern portion of the survey area is thought to be either
associated with or lying immediately north of the Pipestone
Fault.
The causative body of conductor C-l is thought to
be a finely disseminated sulfide band associated with a tuff
horizon lying within the mafic metavolcanics.
RECOMMENDATIONS
In light of the proven structural significance of
the Pipestone Fault System as a known channel way for gold
bearing mineralizing solutions, it is strongly recommended that
the structural relationship between the metamorphosed mafic
intrusive body and the Pipestone Fault zone be determined. It
is also recommended that additional ground geophysics be
carried out in the vicinity of Conductor C-l. This additional
work would consist of several selected I.P. profiles carried
out across the inferred axis of Conductor C-l.
All of which is respectfully submitted.
