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.

Cochrane to the Amoco-Campbell-Dome minesite, expected
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

with a McPhar model GP-70 magnetometer to determine total
magnetic field strength.
Survey results were recorded and are presented
here in Fig. A.

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.
