Report for Mattagami Lake Mines Limited covering MAGNETIC and ELECTROMAGNETIC surveys over their NO. 10 CLAIM GROUP, Sturgeon Lake area, Patricia Mining Division, Ontario.

LOCATION AND ACCESS;

This group of 16 contiguous claims numbered P212743 to P212758 inclusive is located in Sturgeon Lake. The group is staked around an island located approximately 1J miles south east of Granite Bay. Access is via Sturgeon Lake.

PREVIOUS WORK;

The GSC airborne magnetic map No. 52-G/14 flown at 1000' shows that the claim group flanks a very strong magnetic high towards the southeast. This magnetic high occurs within the Iak9", but is^attributed to iron formation associated with a band of sediments that strike up Sturgeon Lake then turn towards Barge and Port Lakes. The ODM geological map No. 2169 shows the island as being composed of mafic metavolcanics. The area was flown by Questor for Mattagami Lake Mines with the claim group being staked to cover four airborne EM anomalies located on the island and the bay on its eastern shore.

EQUIPMENT USED;

Magnetic- A McPhar fluxgate magnetometer K-700 was used measuring the vertical component of the magnetic field directly in gammas. Accuracy of the instrument is 10 gammas. Normal Procedures using base stations and applying drift corrections were carried out.

Electromagnetic- A Crone Shoot back JEM unit was used with a coil separation of 300' and a basic operating frequency of 1800 Hz with readings also being taken at 480 Hz in anomalous areas. The "resultant dip angle" in degrees is recorded using the mid point between the two operators. This instrument was also used for some detail work from line 12E to line 32E adjacent to the base line using the fixed transmitter vertical loop method and running the 400* line with a receiver.

A Crone RADEM-VLF-EM instrument was also used for detail work measuring both the dip angle of the field in degrees and the Field Strength as a percent of normal Held Strength.

LINECUTTING:

A baseline was established with an azimuth of 40 0 and a grid cut with a 400' time interval over the entire claim block. Linecutting and picketing over the lake was conducted by Mattagami Lake Mine's own crews. A total of l mile of hase line and 13.2 miles of line were established.

INTERPRETATION:

Three conductors were detected no. 10-1, No. 10-2 and No. 10-3.Conductor No. 10-1 is a well defined anomaly with high

conductivity/ a length of 600* and a width that could be as much at 50'. The conductor dips at approximately 60 0 towards grid north with magnetic correlation being poor to nil.

Conductors 10-2 and 10-3 are weak and poorly defined even with the considerable detail work carried out. A banded deeply buried bedrock conductor or a near surface clay bed could explain the anomaly.

^Two drill holes are proposed.

No. l Line 32E, 8 4- 00 N drilling at -45 0 in a grid south direction for 400'

No. 2 Line 20 E, l -f 50 N drilling at -45 0 in a grid south direction for 500'
