INTRODUCTION

A horizontal loop electromagnetic survey, an

EM-16 VLP survey and a magnetic survey were carried out on

Project 159L for Dome Exploration (Canada) Limited in

November, 1983.

The property comprises 16 claims and is located in

the Tomorrow Lake area - Detour Lake, Ontario. The grid is

located approximately 6k miles northeast of Cochrane, Ontario.

Access to the property was by helicopter from La Sarre, Quebec,

The purpose of this survey was to locate conductive

zones which might be related to economic sulphide bodies. No

conductors were located. The accompanying maps show the area

surveyed and the results obtained.

A technical data sheet is appended to this report.

METHOD AND INTERPRETATION OF RESULTS - ELECTROMAGNETIC SURVEY

Operating Principle; When an electrical conductor is subjected to a

primary alternating field, a secondary current is induced in the

conductor. This current produces a secondary alternating field

which together with the primary field produces a resultant field of

different amplitude and phase from the applied primary field. These

differences may indicate the presence of a conductor*

Operation; The battery-powered transmitter sets up a primary field

while the in-phase and out-of-phase (quadrature) components of the

complex secondary vertical field are detected by a receiving coil

and measured by means of a compensator-amplifier unit located a fixed

distance from the transmitter unit. These parameters are expressed

in percentage of the primary field*

Conductor Recognition; The typical curve over a steeply-dipping conductor

shows a low (negative - greater than 5/") over the centre of the

conductor, flanked by positive readings on both sides of the conductor.

Both the in-phase and the out-of-phase components usually produce

the same general shape of curve. An asymmetrical curve may indicate

one or more of the following conditions: (l) more than one conductor

(2) variable conductive overburden (3) a shallow dipping conductor.

Conductivity Determination; The ratio of the amplitudes of the two

measured components, in-phase to out-of-phase, is directly proportional

to the conductivity of the conductor, in areas of non-conductive

overburden .

Conductor Location; For a single conductor, both component readings are

normally zero when either the transmitting or receiving coil is

directly above the conductor. The location of the conductor is cal

culated by adding one-half the distance between the transmitting coil

and the receiving coil (coil interval) to the co-ordinate at which

the readings are zero. A unique solution is generally not possible

in the case of multiple conductors spaced less than one coil interval

apart. This results in the possibility that an apparently wide

conductor may actually consist of two or more narrow conductors.

Depth of Penetration; The maximum depth of penetration for detection of

a steeply-dipping conductor in a geo-electrically neutral background

is about O.? times the coil interval. Over horizontal or flatly-

dipping conductors, penetration of up to 1.5 times the coil interval

is possible.

RESULTS

The horizontal-loop E.M. survey (Map 83-28O) Tailed

to outline an anomalous zone that could be considered a drill

target. The lack or response could be due in part to the fact

that the area is wet, mostly swamp covered and the depth to

bedrock is unknown.

The VLF survey (Maps 83-282 and 83-283) is uninter

esting with no significant response worth drill testing. At

the northern end of Line 6E there is a slight E.M. response.

However, with no corresponding horizontal-loop or magnetic

anomaly this zone is unimportant.

The magnetic survey (Map 83-281) has outlined a zone

with a maximum intensity of 6O,219 gammas on Lines OE, IE and

2E. This feature may continue to the west of the surveyed

area. A minor magnetic feature is outlined on Lines 4E and

5E which appears to have a north-south strike.

On the basis of the geophysical results, no drill

targets are indicated.

Re; Your File Nos. 2.6701 - 2.6703 incl.

Dear Sir:

Further to your letters of July 9, 1984 and our recent telephone conversation regarding the plotting of the actual reading at each station on the V.L.F. Survey plans which were returned with your letters, we indicated, that due to the cost factor, the con siderable amount of time required and the shortage of personnel to post these readings, would delay the return of these plans to you.

We, therefore, request you waive this requirement as to the above-mentioned surveys and we will make certain that future submissions will have all readings plotted as per your requirements.

Tour favourable consideration to this request will be greatly appreciated.
