INTRODUCTION
Oeophysical surveys, consisting of electromagnetic
and magnetometer, have been completed on the property of
Conwest Exploration near Princess Lake in the Sturgeon
Lake area of Ontario.
The following report and accompanying maps describe
the results of the surveys and give an interpretation of
same.
PROPERTY AND LOCATION
Only a portion of the claim group was surveyed, as
shown on the accompanying maps. The claims covered
included all or part of the following, registered with the
Ontario Department of Mines:

Tha property is situated at Prinoaaa Lake, east of
Sturgeon Lake, and about 60 miles by air from the basa at
Ignace. It is located 16 miles east of highway 599 and
about 13 miles northeast of the Mattagami discovery.
GEOLOGY
The geology of the area is described in Geological
Report No. 24 with accompanying map 2044 and also Pre
liminary Map No. P 353, all published by the Department
of Mines of Ontario*
From this data, the property surveyed appeara to be
largely underlain by meta-sediments which are known to
include conglomerate, arkose, greywacke and derived
schists. The extreme northwest corner of the surveyed area
is shown to be underlain by syenitic rocks that have intru
ded the surrounding meta-sediments and roeta-volcanics. Tha
general trend of the rooks is northeast.
SURVEY METHODS AND INSTRUMENT DATA
The survey was carried out using a network of picket
- 3 - PROSPECTING GEOPHYMC* LTD.
lines cut in a northwest direction at 400 foot intervals,
as shown on the accompanying maps. Stations were at 100
foot Intervals along the lines.
The electromagnetic survey was carried out using
the Ronka Mark 32 horisontal loop equipment with a 300 foot
coil interval. In the horisontal loop type of survey
bofih the in-phase and out-of-phase components of the
secondary field are measured, whose special characteristics
make possible a fairly accurate evaluation of the conduc
tivity. A conductor caused by sulphide mineralization
wixl produce a curve going from positive readings through
zero to negative and back again to positive. Both the
in-phase and out-of-phase readings show the same general
curve. The ratio between the in-phase and out-of-phase
readings over a conductor is an indication of the con
ductivity of the body. A good conductor would cause a
greater deviation of the in-phase component than the out-
of-phase component. The opposite is true of a poor .
conductor.
The magnetic readings were taken over the same net
work of lines with a Sharpe MF-1 Fluxgate in.^etometer

measuring the variations of the vertical component of the
earth's magnetic field. Readings were plotted as gammas
on a separate map after correction for diurnal variation.
RESULTS OF THE GEOPHYSICAL SURVEYS AND INTERPRETATION
The magnetometer survey outlined a number of
irregular magnetic anomalies that trend in a northeast
direction. The magnetic anomalies are all located in the
northeast portion of the property and appear to be located
along a northwest trending structure. The anomalies hare
values in the thousands of gammas, as compared to a back
ground of 500 to 600 gammas. The magnetic anomalies in
all probability represent more basic rocks with a higher
magnetite content than the balance of the property.
The electromagnetic survey outlined several conduc
tive cones trending in a northeast direction, all within
the magnetic anomalies. The conductive tones are quite
strong and from the intensity of the readings there ia very
little overburden covering the conductors. The major
conductors are located in the eoutheast corner of the area
surveyed and these appear to be en echelon with two of
these going off the area surveyed. The dip appears to be

near vertical and one of the zones has a width of approxi
mately 50 feet. Since the conductors are within the magnetic
anomalies, it is difficult to determine if there is a
magnetic high coincident with the conductor.
In the northwest corner of the area, a similar con
ductive zone within a strong magnetic anomaly was outlined.
On line 40E, the profile has been interpreted as two con
ductive sones rather than one fairly wide tone.
CONCLUSIONS AND RECOMMENDATIONS
The geophysical surveys outlined several strong con
ductive zones trending northeast within magnetic anomalies.
There is a good probability that sulphides are at least a
contributing cause for the conductivity. The intensity of
the readings suggests that the overburden is light and it
is recommended that geological examination is made prior to
investigation by diamond drilling. There is a possibility
that the cause can be determined by trenching, but, if not,
diamond drilling is recommended for the major sones.
