INTRODUCT10N;

A total field magnetometer and VLF-EM survey was

performed over the Corrie Copper Ltd. property in the Lower

Detour Lake area of northeastern Ontario in April, 1983.

The survey was an attempt to define regions of

sulphide mineralization believed to be associated with gold

deposits in the region.

Survey techniques, results and recommendations

for further exploration are discussed in the following text.

LOCATION AND ACCESS:

The property consists of forty-seven (47) mining

claims numbered 622330 to 622349 inclusive, 624503 to 624517

inclusive, and 624789 to 624800 inclusive. The claims are

located approximately three (3) kilometers east of Lower

Detour Lake, in the Lower Detour Lake area, Porcupine Mining

Division, situated approximately 140 kilometers northeast of

Cochrane, Ontario and 120 kilometers north of La Sarre,

Quebec.

Access to the property during the winter months

is by winter road to the Detour Mine site area, and then by

snowmobile to the property. Access during the summer months

is by float plane to Lower Detour Lake, and then on foot to

the property.

to be completed by the autumn of 1983, will provide all year

access to the general Lower Detour Lake area.

SURVEY PARAMETERS;

An approximate east-west baseline runs along the

northern boundary of the Corrie Copper Ltd. property. Cross-

lines were cut on 100 meter centers along the baseline and

extended to the property's southern boundary. Stations were

located at 25 meter intervals along the crosslines.

Approximately 92 kilometers of line were cut and

chained.

VLF-EM Survey;

Approximatley 87 line-kilometers were surveyd

with a Geonics EM-16 VLF Electromagnetic Unit at 25 meter

interval stations along north-south crosslines. The trans

mission source was Cutler, Maine, transmitting at 17.8 KHz,

Survey results were recorded and are presented

here in Fig. 3 .

Proton Magnetometer Survey :

Approximately 91 line-kilometers were surveyed

REGIONAL GEOLOGY

"The sequence of rocks in the Detour Lake Area

consists of Pre-Cambrian mafic to felsic metavolcanics and

metasediment s of the Abitibi Greenstone Belt. The meta

volcanics and metasediment of this area were later intruded

by both felsic and mafic plutons and dykes.

The mafic metavolcanics are fine grained and

have well preserved primary structures. The main lithologic

types are as follows: flows, tuffs, pillow flows with auto

clastic breccia, lapilli-breccia to pyroclastic breccia andporphyritic flows.

The felsic to intermediate units are not exposed

in outcrop and have been delineated using diamond drill hole

logs and ODM-GSC aeromagnetic maps. Chemically all the felsic

to intermediate metavolcanics are calc-alkaline rhyolites

and dacites with minor tholeiitic dacite.

The "clastic metasediments are found stratigraph-

ically above the metavolcanics. Diamond drill hole logs

also show that they are interbedded with metavolcanics.

The metamorphosed mafic and ultramafic intrusive

rocks consist of gabbro, porphyritic gabbro and amphibolite.

These occur as feeder dykes and sills. The ultramafic

intrusive rocks are not exposed on the surface.

The felsic to intermediate intrusive rocks are

mainly quartz monzonites that are occasionally pegmatitic.

-5-

The metavolcanic-metasedimentary rocks of the

northern supracrustal belt in the Detour Lake Area lie at/

or within the nose of a fold structure which extends west

from the main body of the Abitibi volcanic belt in Quebec.

The northern supracrustal belt is isoclinally folded into

an anticline and a series of antiforms and synforms. The

emplacement of the Detour Lake diorite warped the fold

axis of the and induced minor folding in the metavolcanics

surrounding the body. The anticline found north of Detour

and Lower Detour Lakes plunges gently to the northwest at

about 45 degrees. The location of the axis of the anti

cline is delineated by lithologic changes found in diamond

drill logs and opposing pillow tops found on the north and

south limbs.

Major faults have not been proposed for the

map area because the amount of outcrop is insufficient and

the overburden too deep for such interpretation.

The foliation in the Detour Lake Area tends to

parallel bedding and is defined by the planar orientation

of platy and acicular minerals such asbiotite, chlorite,

muscovite and amphibole and by flattening of clasts and

pillows.

The rocks in the Detour Lake Area have under

gone regional and contact metamorphism, ranging from upperi

greenschist to almandine amphibolite facies."

INSTRUMENTATION:

Total Field Magnetometer;

The proton (or nuclear precession) magnet

ometer 'utilizes the precession of spinning protons in a

sample of hydrocarbon liquid to measure total magnetic

intensity. The protons, or hydrogen nucleii, within the

sample : .are polarized normal to the terrestrial field

by means of a current through a surrounding coil. Upon

sudden removal of the polarizing field the protons precess

about the direction of the earth's magnetic field at an

angular velocity (the Larmar precession frequency) pro

portional to the magnetic field strength. The processing

protons being moving charges, induce a voltage in the same

coil used to polarize them, which is measured by a digital

counter to obtain the Larmar precession frequency. The

total magnetic field F is then determined from the relation

Larmar precession frequency

"J^B- Gyrometric ratio of the proton

(ratio of its magnetic moment to

its spin angular momentum).

The advantages of the proton magnetometer over

other types include its high sensitivity, its lack of mech

anical parts in its detector element, and the fact that it

has no orientation or levelling requirements.

The McPhar GP-70 proton magnetometer, the model

used for this magnetic survey measures the absolute magni

tude of the total magnetic field within the range of 20,000

-7-

to 100,000 gammas, to an absolute accuracy of -l gamma.

Additional instrument specifications are presented in

Appendix I.

Repeated readings at a specified base station

at a miximum of 90 minute intervals enabled correction of

diurnal variations in the magnetic field and to a lesser

extent instrument drift.

VLF-Electromagnetic Unit;

The VLF-EM method - utilizes the worldwide

network of high-powered VLF (very low frequency) trans

mission stations used for air and marine navigation. The

VLF antenna is effectively a grounded vertical wire several

hundred feet high, emitting a near vertical electric field

component and corresponding concentric horizontal magnetic

field. The large power output of the stations (500 -1000 KW),

along with minimal attenuation, make it possibe to use VLF

transmitters as EM sources at distances of 2000 - 3000 miles.

At these distances it is reasonable to consider the magnetic

field as being uniform over areas of up to a square mile of

ground surface.

When the primary horizontal magnetic field

encounters conductive sub-surface bodies, secondary fields

are induced. The VLF receiver measures the vertical

component of the resulting secondary fields, determining

tilt angle and quadrature component by means of two mutually

perpendicular coils wound on ferrite cores. That is, if the

secondary signals are small in comparison to the primary '

filed, the mechanical tilt angle is an accurate measure of

-8-

the vertical real-compinent, and the compensation

signal from the horizontal coil is a measure of the quad

rature vertical signal.

The advantages of the VLF-EM include its rel

ative ease and low cost of operation. Although minimal

interpretation of anomaly depth, depth extent and dip

angle is possible, due largely to the lack of control

over the primary field direction with respect to conductor

strike, the VLF system provides a usually reliable method

of defining the conductor strike and extent.

The Geonics EM-16 was used in the VLF-EM survey

of the Corrie Copper Ltd. property of the Lower Detour Lake

area, specifications for which are presented in Appendix I.

The transmission station used was Cutler,

Maine, transmitting at 17.18 KHz.

INTERPRETATION:

VLF-EH Survey;

Nine predominent conductive zones are apparent

from the accompanying VLF-EM profile map (Fig. 3), defining

a general NW-SE trend.

Conductor "A"- Centered on Line 4 at station

5+00 S, conductor "A" shows moderately strong in-phase

response with well-defined crossover points. Negative quad

rature response suggests a bedrock source.

Assymmetry of the in-phase profile indicates a

slight northerly dip. Depth is estimated at 80 meters.

A very slight magnetic response coincides with

the conductor, possibly indicative of pyrrhotite or magnetite

mineralization at depth.

Conductor ^B" - Located on Line 9 at station

8+OOS, conductor "B" is of limited extent (approximately

200 meters). Weak to moderate in-phase response with a

definite crossover point is evident.

The nature of the quadrature profile and the

absence of coinciding magnetic response strongly suggests

an overburden source.

-10-

Conductor "C" - is of relatively large extent

(approximately 500 meters), spanning Lines 19 to 23 to the

north of the property. Moderate to strong in-phase response

showing definitive crossover points with weak to moderately

negative quadrature response suggest primarily a bedrock

source with some degree of overburden contribution. Depth

is estimated to range from 40 meters to in excess of 100

meters.

No magnetic response is associated with the

conductor, suggesting possible pyrite mineralization at

depth.

Conductor "D" - Spanning Lines 23 to 28 towards

the north boundary, Conductor "D" shows strong in-phase

response with a relatively flat quadrature profile, sugges

ting contribution from a surface conductor.

Erratic magnetic response in the region might

indicate sulphide mineralization beneath conductive over

burden .

Depth is estimated at 50 to 100 meters.

Cgnductor- "E" - is of limited extent showing

moderate to strong in-phase profiles with corresponding

negative quadrature response. No coinciding magnetic

response is observered.

The conductor may be attributed to pyrite mine^r-

alization at an estimated depth of 100 meters.

-11-

Conductor^'F" ~ Similar in nature and extent to

Conductor "E", this may also be due to a sililar bedrock. source.

Conductor "G" - Extending approximately 500

meters from Line 12 to Line 17, Conductor "G" shows moderate

to strong in-phase response with a strong negative quad

rature profile. Depth is estimated at 80 neters. A bedrock

source similar to Conductors "E" and "F" is suspected.

Conductor "H" - also shows the characteristics

of pyrite mineralization at an estimated depth of 50 to 100

meters .

I^ - spans Lines 1 to 11 in the south-

west corner of the property. Although strong in-phase

values are indicative of a bedrock source, a relatively flat

quadrature profile suggests evidence of conductive over

burden.

-12-

PROTON MAGNETOMETER SURVEY;

Fig. 4 shows relatively flat magnetic response

over the majority of the property, with the exception of the

northeast corner. Several strong anomalies are evident in

this region, defining a genral east-west trend. Based on profiles along Lines 27 and 32, depth is estimated at 30 to

60 meters.

Minimal VLF-EM correlation may suggest some

degree of disseminated mineralization, possibly pyrrhotite,

in this region. i

A zone of somewhat weaker magnetic response

spans Lines 11 to 16 at station 21+00, similar in strike and

extent to VLF-EM Conductor "G", though displaced to the

south. Based on coarse half-width analysis depth is estimated

at 25 meters below surface.

-13-

CONCLUSIONS AND RECOMMENDATIONS;

The total field magnetometer survey conducted

over the Corrie Copper Ltd. property in the Lower Detour

Lake area shows high magnetic relief in the northeast

corner, with minimal VLF-EM response, suggesting areas of

ultramafic intrusions and/or disseminated sulphides. This

region may be investigated further by Induced Polarization

survey, a method proven successful in neighbouring prop

erties, in an attempt to identify regions of sulhide

dissemination and/or resolve apparent multiple anomalies.

j

VLF-EM survey result reveal several conductors

of varying strength. The nature of a number of the VLF-EM

profiles, however, tend to indicate that conductive over

burden is a contributing factor. Overburden depths of up

to 50 and 60 meters are not uncommon in the Lower Detour

area, and can effectively abstruct VLF-EM detection of

possible sulphide mineralization. It is therefore suggested

that other methods, such as a horizontal loop EM or Induced

Polarization survey be used, particularly in those areas

of greater depth penetration and of somewhat more conclusive

differentiation between surface and bedrock sources.

In conclusion, it is recommended that the

following surveys, or variation thereof, be performed in

order to properly evaluate the significance of the detected

VLF-EM and magnetic anomalies;

Induced Polarization: Line 6, stations 16+00 S to 25+00 S

Line 14, stations 16+00 S to 21+00 S

Line 23, stations 5+00 S to 9+00 S

Line 26, baseline to 9+00 S

Line 32, baseline to 9+00 S

EM16 rLF Electromagnetic Unit

Pioneered and patented exclusively by Geonlcs Limited, themethod of electromagnetic; mirveylng has been proven to

be a major advance In explninllon isophysical Instrumentation.

Since the beginning ol 1965 H IHMJH numbur of mining companies have found the EM II) kyttom to meet the need for a simple, light and effective exploration tool for mining geophysics.

The VLF method uses the military and time standard VLF transmissions as primary field. Only a receiver is then used to measure the secondary fields radiating from the local con ductive targets. This allows a very light, one-man instrument to do the job. Because of the almost uniform primary field, good response from deeper targets is obtained.

The EM16 system provides the In-phase and quadrature components of the secondary field with the polarities indicated.

Interpretation technique has been highly developed particularly to differentiate deeper targets from the many surface indications.

Principle of OperationThe VLF transmitters have vertical antennas. The magnetic signal component is then horizontal and concentric around the transmitter location.
