SUMMARY AND RECOMMENDATIONS
HLEM and magnetic surveys were carried out over the Wark 12 property for Falconbridge Limited in
November 1997.
The magnetic survey outlined two areas of higher magnetic field which are believed to be underlain by
volcanics. The HLEM survey outlined three bedrock conductors. Anomaly 'A' and 'B' appear to have been
the target of holes drilled by Hollinger in 1974; the conductivity is due to graphite close to the contact
between sediments and volcanics. Anomaly 'A' should be tested on Line 1100 South where, although the
EM anomaly is poorly defined, the magnetics are the strongest. Anomaly 'C' is a questionable response
in the high frequency results and it is recommended that the grid is extended to the north and east to better
define this anomaly.

INTRODUCTION
Magnetic and horizontal loop electromagnetic (HLEM) surveys were carried out on the Wark 12 property
for Falconbridge Limited during November of 1997.
The property is located approximately 17 kilometres north of the city of Timmins (Figure 1(a)) in the
Porcupine Mining Division. It was accessed from Highway 655 which cuts through the southwest corner of
the property.
The grid on the property covered part of claim 1203786 which consists of 8, forty acre claim units in the
south half of Concession l, Lots 9 and 10 (Figure 1(b)).
The magnetic survey was run by C. McKay and the HLEM survey was carried out by B. LeRoy and the
author of this report.

GENERAL GEOLOGY
The geology of Wark Township was first mapped by Berry (1939) as part of eight townships comprising
the Bigwater Lake area. Most recently, Berger (1994), mapped Murphy and Wark Townships at a scale of
1:20,000.
The geology of Wark Township consists of Archean ultramafic to felsic metavolcanics and clastic
metasediments which have been intruded by ultramafic, mafic and felsic plutonic rocks and Nipissing
diabase dikes (Berger, 1994).
The Wark 12 property is underlain by north northeast to north northwest striking volcanics which are
surrounded by sediments. Previous drilling intersected graphitic horizons close to the contact between the
sediments and volcanics. Minor zinc mineralization was noted in a lot of the holes.
PREVIOUS WORK
The following is a description of previous exploration work carried out on the property (Table 2).

Table 2. Summary of previous assessment work.
In the early 1970's, Hollinger Consolidated Gold Mines Ltd. carried out an exploration program in Wark
Township on ground held by Victoria Algoma. The program included EM and magnetic surveys over the
south half of Concession l, Lots 9 and 10 and the north half of Concession l, Lot 9. The surveys were run
on lines spaced every 200 feet and oriented at 90 degrees Az. and 60 degrees Az. A number of holes were
drilled to test EM anomalies, four of which are located within the present survey area.
Four holes were drilled directly to the east and north of the present survey area by Bruce-Presto. The
exact year of this work is unknown to the author.
In 1988, the Ontario Geological Survey (OGS, 1988) conducted a combined airborne magnetic and
electromagnetic survey in the Timmins area which included Wark Township. The survey was flown along
north-south lines spaced approximately every 200 metres.
SURVEY DESCRIPTIONS
A north-south base line, designated 14000 East was established at the boundary between Lots 9 and 10
and east-west grid lines were cut every 100 metres and picketed every 20 metres (Figure 1(b)). Tie lines
were also established at 13600 and 14400 East.
The magnetic readings were taken every 10 metres with a Scintrex IGS-2/MP-4. This instrument is a
proton precession magnetometer which measures the earth's total magnetic field to an accuracy of 0.1
gammas. Diurnal variations were monitored every 10 seconds with a Scintrex MP-3 base station
magnetometer which was located off the property at 10200 East, 10360 North; the base station value, to
which all of the readings were levelled to, is 59237 nT.. A total of 962 readings were taken along 9.5
kilometres of line.
The horizontal loop EM survey was carried out with the Apex Parametrics MaxMin I-5. This instrument
measures the in-phase and quadrature components of the secondary field as a percentage of the primary
field; the depth of penetration is approximately half of the coil separation. Readings were taken every 20
metres along all of the grid lines using a coil separation of 160 metres and frequencies of 444 and 1777
Hertz. A total of 338 stations were sampled along 7.7 kilometres of line.
MAGNETIC RESULTS
The magnetic results are posted and contoured every 25 nT on Map 1 at a scale of 1:5000. A colour
image of the total magnetic field is also given in Figure 3 at a scale of 1:10,000.
Two areas of high magnetic field were outlined in the survey area. One trends north northeast between
13600 East on Line 1400 South and 13800 East on Line 900 South. This low amplitude anomaly is believed
to reflect volcanics which were intersected in Holes 6,12 and 13, drilled by Hollinger in 1974. The second
area of high magnetic field is located in the northeast corner of the survey area. This much higher response

is also believed to reflect volcanics .
HLEM RESULTS
The results of the HLEM survey are given in maps 2 and 3 at a scale of 1:5000; the profile scale is 1cm
= 200Xo for both frequencies. The results are also presented in Figure 3 at a scale of 1:10,000. The readings,
particularly in the low frequency results, are quite noisy because of the power line on the west edge of the
survey area.
Three bedrock conductors, labelled 'A1 , 'B1 and 'C' on the maps, were detected in the survey.
Anomaly 'A' represent a faulted or tightly folded zone of conductivity which strikes north northeast from
13620 East on Line 1200 South to 13780 East on Line 800 South. The anomaly is difficult to interpret
because of the noise level and the low amplitude , however, the fact that the anomaly is only a quadrature
response in the low frequency results indicates a very poor conductivity.
This anomaly was tested by Holes VA5-6, 12 and 13, all of which intersected graphitic sediments. It
should be tested on Line 1100 South where, although the EM anomaly is poorly defined, the magnetics are
the strongest.
Anomaly 'B1 strikes north northwest from 14340 East on Line 1400 South to 14080 East on Line 900
South and north-south between Lines 900 and 800 South. This anomaly also has very little in-phase
response in the low frequency results which suggests a very poor conductivity. It is located along the west
flank of a high magnetic anomaly which is believed to represent intermediate to mafic volcanics.
This anomaly was tested by Hole VA5-2 to the north of the present sgrid and Hole VA5-11 on Line 1400
South; both of these holes also intersected graphitic sediments.
Anomaly 'C* is a questionable anomaly in the high frequency results at 14240 East on Lines 800 and 900
