Dear Mr. Harquail:

Submitted herewith is our report entitled:

GRID C

MAGNETOMETER AND ELECTROMAGNETIC SURVEYSWALKER 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.

Two magnetically inferred fault zones were identified during the course of the survey, both of which are believed to be related to the Pipestone Fault system and reflect two periods of structural deformation. Conductivity along the fault zone is unremarkable. Conductor C-2, located in the south-central portion of the survey area exhibits a very weak conductivity response and is interpreted to be either a zone of finely disseminated sulfide mineralization or a region of highly conductive overburden.

In light of the 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 inferred location

of the Pipestone 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 ^5?; 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 lies in the southwest corner of Walker

Township, District of Cochrane and is accessible by truck

approximately l mile east from the village of Monteith on

Highway 626, then west onto a Lot line which swings south along

the eastern boundary of the property.

The West Railway property consists of the following

four 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

supervision of Mr. Gordon Mcintosh of Timmins, Ontario during

the period from October 18, 1979 to March 27, 1980. The survey

grid consisted of 0.7 kilometres of baseline trending E-W and

6.24 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

on 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 August 14 to

August 16, 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 drom August. 14 to August 16, 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 30 metre station interval. These

data are presented in profile form.

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.

Two magnetically inferred fault zones were identified

during the course of the survey. These appear to be related

to two distinct periods of structural deformation. In the

south-central portion of the survey area, a fault zone, charac

terized by a trough of low magnetic relief of up to 250nT

within a region of high magnetic relief, was mapped on line

5W at station 3+90S, trending east-northeasterly to a point

270 metres south of the baseline on line 1W. At this point

the fault appears to be terminated by a north-northwesterly

trending fault zone, characterized by moderately low, below

background magnetic relief and the disruption of adjacent

established magnetic trends.

A lenticular magnetic expression of up to SOOnT, was

mapped on line 2W at station 120S trending north-northwesterly

across the property to a point 390 metres north of the base

line on line 3W.

The electromagnetic survey identified two anomalous

conductive zones lying within the survey area, both of which

will be discussed in the following section of the report. The

somewhat erratic response parametres recorded on line O are

attributable to cultural interference and related to the town

ship road which lies parallel to and coincident with line 0.

Conductor C-l;

Conductor C-l transects the northwest corner of the

area trending NE from L7W to L5W and is classified as a cultural

anomaly, ie. caused by man-made bodies. Conductor C-l is the

mappable expression of a power transmission line.

Conductor C-2;

Conductor C-2 is located in the east-central portion

of the survey area and was mapped on line 1W at station 45S

trending southwesterly across the survey area to a point 100

metres south of the baseline on line 2W. This anomalous

conductive zone exhibits a very poor conductivity response and

has been interpreted to be either a zone of finely disseminated

sulfide mineralization or a region of highly conductive over

burden.

CONCLUSIONS

The ENE trending fault zone is believed to be a

portion of the Pipestone Fault zone which has been offset by

the NNW fault zone. Conductivity along the fault appears

unremarkable as far as the electromagnetic data can be extra

polated; however, since the data does not extend far enough to

the south, it is inconclusive.

RECOMMENDATIONS

In light of the structural significance of the

Pipestone Fault system as a known channel way for gold bearingt

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 Pipestone 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 (<5% sulfides). The ground

geophysics will be followed up by detailed section diamond

drilling along the fault trace.

All of which is respectfully submitted.

Sincerely yours,
