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

Page 7: MAGNETOMETER AND ELECTROMAGNETIC SURVEYS STOCK … · 42aieswei27 2.3569 stock 010 report o n grid a magnetometer and electromagnetic surveys stock township district of cochrane porcupine

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-

Page 8: MAGNETOMETER AND ELECTROMAGNETIC SURVEYS STOCK … · 42aieswei27 2.3569 stock 010 report o n grid a magnetometer and electromagnetic surveys stock township district of cochrane porcupine

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.
