1. Jntroduction

During the period March 16-24, 1987, a coombined airborne

magnetometer and V.L.F. survey was completed by Terraquest

Surveys for Noranda Exploration Company Limited. The survey

covered a group of fourteen claims within Keefer Township.

2. Location of Survey Area

The fourteen claims covered by this report are P781305,

781306, 781308, 781310, 781314, 781315 and P835703 to 835710

inclusive. The claims are located in southern central Keefer

Township, approximately 45 kilometers southwest of the City of

Timmins, Ontario. Map l presents the location of-the claims.

Excellent road access to the property is afforded by Highway

101 west from Timmins. The highway passes through the eastern

portion of the claim group.

3. Survey Equipment. Specifications and Procedures

The survey aircraft utilized was a Cessna 182, registration

C-FAKK.

The magnetometer employed for the survey was a GEM Systems

GSM-9BA proton precession unit which measured the earth's total

magnetic field with an accuracy of 0.5 nT. The sensor was

mounted in an extension of the right wing tip of the survey

aircraft. A GEM Systems total field magnetometer was*employed as

a base station to monitor the duirnal variation of the earth's

magnetic field and to enable correction of the survey data.

A TOTEM 2A V.L.F. unit was employed for the survey with the

sensor mounted in an extension of the left wing tip. The total

field strength and quadrature components of the secondary E.M.

field were measured with an accuracy of 11. The transmitter used

for the survey was NAA, Cutler, Maine operating at a frequency of

24 k Hz.

Other equipment within the aircraft included a King KRA-10A

radar altimeter, an URTEC UDAS-100 digital data acquisition

system with bigidata nine track tape recorder and a Geocam video

flight path tracking camera and recorder.

The survey was flown with a line spacing of 200 metres and

at an average terrain clearance of 100 metres. The survey

aircraft was maintained at an average airspeed of 155 km/hr.

Navigation was visual based on 1:20000 scale photomosaics.

The navigator manually recorded fiducials over recogniziable

terrain features and these fiducials were later verified by

comparison with the video flight path record.

A total of approximately 800 line km was flown over the

survey block.

4. Data Presentation

Total field aeromagnetic data are presented on Map 2 in

contoured plan format at a scale of 1:20000. A contour interval

of lOnT has been employed in the presentation.

t

VLF data are presented as contours of total field strength

and profiles of the quadrature component on Map 3 at a scale of

1:20000. A contour interval of 2% has been employed in the

presentation of the total field strength.

Prominent topographic features, claim boundaries flight

lines and fiducials are also shown on Maps 2 and 3.

5. Discussion of Results

a) Magnetometer Data

Available geological information indicates that te claim

group is underlain by a greenstone sequence of intermediate to

mafic volcanics intruded by felsics and diabase dykes.

Two dominant trend directions are displayed by the magnetic

data - an easterly and a northerly direction.

The easterly trend direction relfects the presence of mafic

volcanic flows. Within the claim group, this magnetic signature

is best displayed over claims P781305 and 781306 where a

lenticular, narrow magnetic high is defined. Similar mafic flows

are suggested as the source of the magnetic high south of claim

835706.

The lenticular easterly trending high over a claim 835703

displays the greatest magnetic relief in the area of the claim

group. An iron formation may be inferred as the probable

causative source.

Northerly magneic trends are defined with claims 781305 and

781315 and within 835704 and 835705. These trends are

characterized by generally linear responses due to diabase dykes.

The large northerly trending area of low magnetic relief

over the central portion of the claim group is inferred to be due

to a granitic intrusive.

b) V.L.F. Data

The V.L.F. data are characterized by few consistent

indications of bedrock conductivity.

Two east-northeasterly trending zones of conductivity, as

defined by the total field strength, appear along the northern

boundary of the property.

The first zone is defined close to the northern boundaries

of claims 781305 and 781306 and appears as a discontinuous

feature. This discontinuity, in the vicinity of flight lines 353

and 354 probably reflects the presence of the northerly trending

diabase dyke defined front the magnetic data. This conductive

feature displays no magnetic association and a graphitic/pyritic

source may be suggested.

The second zone, extending through claim 83S703, appears as

a linear feature displaying a coincident magnetic expression. A

sulphide iron formation is suggested as the probable causative

source of this feature.

The remaining V.L.F. responses over the property are poorly

defined and have little correlation with trend dirrections

discernible from the magnetic data.

6. Conclusions

The magnetometer data have aided in the definition of

certain lithologies within the claim group.

The E.M. data have defined two conductive trends

underlyingthe property. The most prominent response within the

northeastern portion of the property is suggested as having a

sulphide iron formation as its causative source.
