Dear Mr. Harquail:
Submitted herewith is our report entitled:
GRID A
MAGNETOMETER AND ELECTROMAGNETIC SURVEYSSTOCK TOWNSHIP
DISTRICT OF COCHRANE PORCUPINE MINING DIVISION
ONTARIO
The Pipestone Fault zone was further defined during the course of the ground geophysical surveys. Magnetically, the fault zone is characterized by the sharp magnetic susceptibility con trast exhibited by the two adjacent rock units, the metasediments to the south and the metavolcanics and gabbroic rocks to the north. Conductivity along the fault zone is generally unremarkable.
In light of the proven structural significance of the Pipestone fault System as a known channel way for gold bearing mineralizing solutions, it is recommended that additional ground geophysical investigations be carried out in the vicinity of the Pipestone Fault in order to further define the magnetically in ferred location of the fault. The ground geophysics would consist of several selected I.P. profiles carried out across the fault zone in an attempt to define possible disseminated sulfide zones (<S% sulfides). The ground geophysics will be followed up by detailed section diamond drilling along the fault trace.
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 northwest corner of
Stock Township, District of Cochrane, and is accessible by truck
south from the village of Monteith or north from the village of
Shillingdon on Highway 577, then east on a concession road
between Concession V and VI, a distance of 6 km, to the claim
group.
The Stock Township property consists of the following
twenty unpatented mining claims, all of which have been duly
recorded with Mr. E. Craig, Mining Recorder, Porcupine Mining
Division.

LINE CUTTING
The line cutting was conducted under the direct
supervision of Mr. Gordon Mcintosh, Timmins, Ontario, during
the period from September 22, 1979 to September 28, 1979. The
survey grid consisted of 1.21 miles of baseline trending 80O and
13.78 miles of grid line trending 170O on the northern block,
and 0.45 miles of baseline trending E-W and 1.72 miles of grid
line trending N-S on the southwest block. All grid lines were
established at four hundred foot intervals along the entire
baseline. One hundred foot stations were established on all
lines.
MAGNETOMETER SURVEY
The magnetometer survey was carried out by R. Harwood
of W. G. Wahl Limited during the period from August 26 to
September l, 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 50 foot 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 Mr. J. Palladini of W. G. Wahl Limited during
the period from August 26 to September l, 1980, employing an
Apex Parametrics 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 100 foot station interval. These
data are presented in profile form.t
DISCUSSION
The ground magnetometer survey extended and further
defined the regional geology as mapped by the Ontario Division
of Mines and presented on Map No. 2205.
The Pipestone Fault, believed to transect the central
portion of the property, was mapped at 3+0ON on line O through
to 5+50S on line 64W in the northern block and line 20+OOW at
12+50N and 24+OOW at 11+OON in the southwestern block, trending
approximately N80OE.
The fault zone itself is defined by the sharp magnetic
susceptibility contrast exhibited by the metasediments mapped
south of the fault zone and by the intermediate to mafic meta-
volcanic sequence mapped north of the fault zone. The meta-
sediments are characterized by low uniform magnetic relief in
the range of 250 - 450nT which is in sharp contrast to the
450 - SOOnT associated with the metavolcanic sequence. Lying
with the metavolcanic sequence are several major lenticular
magnetic expressions of up to 3,OOOnT, all of which are thought
to be the mappable expression of metamorphosed mafic rocks,
possibly gabbro or diorite intrusive bodies.
The electromagnetic survey identified three anomalous
conductive zones, two of which are classified as cultural
anomalies, ie. anomalies whose causative bodies are man-made.
Conductor C-l:
Conductor C-l transects the southern portion of both
the north block and the southwest block, and identifies a
buried section of the Trans-Canada Pipeline.
Conductor C-2:
Conductor C-2 lies roughly parallel to and 3,500 feet
north of Conductor C-l from lines O through 28W, then swings
southwesterly to line 24+OOW in the southwest block, at a
point 1,000 feet north of the baseline. This is the mappable
expression of a power transmission line.
Conductor C-3;
Conductor C-3 is located on line 4W at 8+50N and line
8W at 8+50N and has been interpreted to be a bedrock rise.
CONCLUSIONS
The Pipestone Fault zone was further defined during
the course of the ground geophysical surveys. Magnetically,
the fault zone is characterized by the sharp magnetic suscepti
bility contrast exhibited by the two adjacent rock units, the
metasediments to the south and the metavolcanics and gabbroic
rocks to the north. Conductivity along the fault zone is
generally unremarkable.
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 recommended that additional
ground geophysical investigations be carried out in the vicinity
of the Pipestone Fault in order to further define the magneti
cally inferred location of the fault. The ground geophysics
would consist of several selected I.P. profiles carried out
across the fault zone in an attempt to define possible dissemi
nated sulfide zones ^51; sulfides) . The ground geophysics will
be followed up by detailed section diamond drilling along the
fault trace.
All of which is respectfully submitted.
