INTRODUCTION

Over the period of July 10th to 26th, 1964, a

geophysical party, under the direction of Mr. H. Beckmann,

carried out electromagnetic, magnetic and gravity surveys

of an area in Township 25, R. XV, Sault Ste. Marie Mining

Division, Ontario. The object of these surveys was to

precisely locate, delimit and investigate two conductors

indicated by an earlier electromagnetic survey and designated

E- 3 and E-6.

The area covered by these surveys includes all or

part of unpatented claims 67112, 67113, 67114, 67115 and

It lies about one mile northwest of Doyle Lake.

Access is by means of charter aircraft from Sault Ste. Marie,

Ontario, a distance of approximately 45 miles due south, to

Doyle Lake. (See location map Dwg. L-2336)

An Electronic Associates E. M. 5 portable vertical

loop unit was employed on the electromagnetic survey with

an operating frequency of about 1000 c. p. s. The transmitter

coil is maintained with its plans vertical and oriented towards

the receiver location. The receiver coil is tilted about a

a horizontal axis joining it to the transmitter to obtain

the dip of the resultant electromagnetic field. Conductors

are deduced from the presence of appreciable tilt angles of

the electromagnetic field from the horizontal plane.

The survey lines were initially covered by a

reconnaissance parallel line technique, followed by fixed

transmitter locations to improve the conductor definition.

An askania torsion vertical component magnetometer

was employed on the magnetic survey. Appropriate corrections

for diurnal varriations were made by tying back, about once

per hour, to a base station previously occupied.

A World Wide gravimeter was employed on the gravity

survey. Station elevations were measured to a relative

accuracy of about 0.1'. Appropriate corrections were made to

the observed gravity values for instrumental drift and station

elevation.

GEOLOGY

Mapping of the grid area has revealed it to be

underlain largely by acid to intermediate volcanic and minor

sediments, intruded by diabase dykes and granitic bodies of

uncertain extent.

The observed strike direction is approximatelyx.

N 400 W and dips are steep to the northeast, in general.

DISCUSSION OF RESULTS

The electromagnetic results (Dwg. Nos. E-4097-1

and E-4098-1) are presented on two plans, each on the scale of

l" - 2O0 , and the second shows the detail (fixed transmitter)

tilt angle profiles, on the same scale. The latter shows

the conductors deduced from the electromagnetic data.

Two conductors have been located with certainty

and a third possible conductor as well, all strike about

N 400 W. There is one main conductor 2,000 feet in length

and still open to the southeast. It is of very strong

amplitude. The second definite conductor is only about 400

feet in confirmed length and moderately strong.

The magnetometer survey results are presented on

Dwg. M-4099-1, in profile form, on the profile scale of

l" - 1000 gammas. There is considerable magnetic relief,

rangin from 4600 gammas positive to 5400 gammas negative.

The E-3 - E-6 Conductor System displays direct magnetic

correlation on a number of sections, up to 2200 gammas peak

amplitude.

The gravity and elevation survey results are shown

on Dwg. GR-4100-1, in profile form, on the profile scale of

l" - l milligal. There is no significant positive gravity

expression corresponding to any conductor indication on E-3

or E-6. In fact several sections exhibit a negative gravity

correlation.

CONCLUSIONS AND RECOMMENDATIONS.

Two conductors have been confirmed which are

undoubtedly caused by graphite and/or very narrow sulphide

zones.

It is recommended that each of these conductors

should be examined by trenching, if possible, or by

drilling if trenching is not feasible, in order to determine

the conductor cause.

follows:-

Suitable exploratory drill holes would be as

(a) Collar on line 12W at 250 feet north.

Orient southwest along the line for

400 feet @ 45O dip.

(b) Collar on line 16W at 225 feet south.

Orient southwest along the line for

300 feet @ 45O dip.
