INTRODUCTION

An electromagnetic and magnetic survey were carried out

for Placer Dome Inc. on Project 282, Keezhik Lake, Ontario in

September 1986, and March and September 1987. The south west

corner of the claim group was completed in February and March

1988, in conjunction with the adjoining Project 318,

A list of the 31 claims covered by this assessment report

is appended to the report. The claim group is located on and

north of Keezhik Lake, which is located 120 km. east from the

town of Pickle Lake, Ontario. Access to the property was made

via fixed wing aircraft from Pickle Lake, Ontario.

The purpose of the survey was to locate subsurface, geo-

electrical conductors, and outline geological structures as

defined by the magnetics, which may prove conducive for gold

mineralization.

Fifteen conductors were located. The magnetic survey out

lines a major iron formation unit which reveals one tight fold,

plus six transcurrent faults.

The accompanying maps show the area surveyed and the results

obtained.

A technical data sheet is appended to the 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: (1) 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 calculated 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 0.7 times the

coil interval. Over horizontal or flatly-dipping conductors, penetration of up

to 1.5 times the coil interval is possible.

RESULTS

The magnetic data collected was contoured by Dome

Exploration (Canada) Ltd.

The magnetic survey outlines a broad band of

highly magnetized rock with amplitudes in excess of 60,000

gammas above a background of 59,000 gammas.

This banded iron formation reveals many structural

features, namely a tight fold and six apparent transcurrent

faults. To aid in the discussion of these features,

reference will be made to numbers on the accompanying

schematic of the magnetic anomalies, Fig. IV. Two base

lines were used in this survey, with similar line numbers.

To avoid confusion, reference will be made when a line is

part of the Brash Lake Grid and none will be made when the

lines correspond to the Keezhik Lake Grid (Fig. III).

1. This long, linear IF band extends from L14+OOE,

5+25N (Brash Grid, Map 16) to L39+OOE, 7+OON (Brash Grid,

Hap 13). This vertical dipping band is less than 100 metres

wide. Magnetic values are up to 46,000 gammas above

background, being highest on L21+OOE (Brash Grid, Map 17)

where the band is widest.

2. Parallel to this is a second band of IF. This

latter unit is the north limb of a tight fold. It extends

from the edge of the surveyed area at L14+OOE, 1+50S (Brash

Grid, Map 16) to the nose of the fold at L45+OOE, 3+OOS

(Brash Grid, Map 13). The southern limb extends from the

l

- 4 -

nose to L31+OOE, 2+OON (Hap 12), where It Is truncated by a

fault, F2. The northern limb is approximately 100 metres

wide and is vertically dipping. The nose of the fold is

elongated with a large concentration of magnetite at its

tip, centred on L41+OOE, 3+OOS (Brash Grid, Map 13). The

southern limb, which is wider than the northern limb, dips

to the south/southeast. The western extremity of this band

is over 300 metres wide and consists of two distinct

magnetic bands, 250 metres apart,

ie) l - L32+OOE, 2+OON to L36+OOE, 0+00 (Map 12)

2 - L32+OOE, 0+50S (Map 12) to L38+OOE, 3+OOS (Map 13).

There appears to be a dextral fault, FI, passing

through this fold. The fault axis is almost coincident with

L40+OOE of the Keezhik Lake grid. The fault is suggested by

the narrowing of the magnetic contours on the southern limb

between L40+OOE and L41+OOE at 6+25S (Map 13) and the break

in the contour lines of the northern limb at L20+OOE, 1+50S

(Brash Grid, Map 17). The fault appears to displace the

southern limb by 100 metres. No displacement is observed on

the northern limb.

Fault F2 displaces the southern limb of the fold

approximately 600 metres to the south east. This sinistral

fault is located along a line connecting L33+OOE, 8+OOS (Map

13) and L31+OOE, 2+OON (Map 12).

- 5 -

3. The IF unit to the south west of this fault, F2,

Is over 300 metres wide and also consists of two narrower

highly magnetic bands. One of these narrow bands extends

from L29+OOE, 3 + 62S to L12+OOE, 0+25S, (Hap 9). It 1s 50

metres wide and appears to be slightly folded, the nose of

which is centred on L23+OOE, 250S (Map 9). The second more

southerly band extends from L31+OOE, 6+OOS to Lll+OOE, 1+25S

(Map 9). It has a variable width on the order of 150

metres. The entire unit dips to the southeast.

This IF band is truncated by a dextral fault, F3,

located from L7+OOE, 6+OON (Map 8) to L12+OOE, 4+25S (Map 9.

There is an apparent 200 metre displacement along this

fault.

4. The IF unit continues southwest of the fault, F3,

extending from L9+OOE, 0+50N (Map 9) to L6+OOW, 2+50S (Map

6). This 400 metre wide unit dips to the southeast and

still consists of two narrow bands, however the two bands

become less distinct toward the western fault, F4,

boundary.

There is a very pronounced break in the IF unit

between units 4 and 5. A dextral fault extends from

l

- 6 -

L4+OOW, 8+OOS (Map6) to L10+OOW, 3+50N (Map 8) yielding a

300 metre displacement.

5. Southwest of this fault, F4 , the IF extends from

L9+OOW, 0+00 (Map 8) to L15+OOW, 3+OOS (Map 6). The IF unit

continues to consist of two narrow bands which are 200

metres apart. The individual bands are becoming more

narrow. This IF unit dips to the south east, however the

strike is becoming more northerly due to the series of

dextral faults. This unit terminates on a dextral fault,

F5, located between L13+OOW, 7+25S to L18+OOW, 3+75N (Map

6). The apparent displacement 1s 130 metres.

6. The IF band south west of fault F5 extends from

L16+OOW, 2+75S (Map 6) to L29+OOW, 7+OOS (Map 4). The pair

of narrow IF bands are still distinct however they are

becoming narrower and more closely spaced. The entire unit

still dips to the south east. A narrowing of the contour

lines at L29+OOW, 7+OOS (Map 4) suggests a dextral fault,

F6.

7. The iron formation extends from this fault, F6, to

the edge of the surveyed area at L52+OOW, 3+50S (Map 3).

Within this section the magnetic high values are spotted

creating less resolution for the pair of narrow magnetic

bands. This unit dips to the south east and 1s on the order

of 200 metres wide. It is within this section that

conductors #13 and 14 are located.

- 7 -

8. Parallel to this highly magnetic IF there are a

number of less magnetic, 5000 gamma, lineaments. These are

located approximately 200 to 400 metres north of the IF

extending from L22+OOE, 4+OON (Map 12) to L53+OOW, 0+00 (Map

3). These are narrow, non-continuous linear features which

form a definite trend parallel to the IF units. It 1s

within these lineaments that most of the conductors are

located.

The horizontal loop electromagnetic survey located

fourteen conductors. #6 and #7 are long parallel

conductors. #13 and #14 are associated with the iron

formation. Many are one Hne, short strike length

conductors. The following table lists the conductors and

defines their characteristics. The depth estimates and

conductivity thickness product are calculated using the thin

ribbon model.

RECOMMENDATIONS

The magnetic survey outlines a long IF unit which

is broken up by many apparent faults. These structural

features should be investigated and verified by geological

mapping. The absence of outcropplngs may require drilling

for geology.

- 8 -

The conductors are concentrated 1n one general

area, mostly away from the iron formation. Based on

conductivity and width the following are recommended drill

targets.
