CLAIMS 201101 TO 201118 PATRICIA MINING DIVISION

This report describes results of ground magnetic and

electromagnetic surveys undertaken during June 1970 over 18 claims

in the vicinity of Pashkokogan Lake, Patricia Mining Division.

Location and Access

The claims are on the south shore of Pashkokogan Lake

near the mouth of the Pashkokogan River and six miles east of the

Savant Lake-Pickle Crow highway. Access is by this highway,

thence by canoe, or by float- or ski-equipped aircraft landing on

Pashkokogan Lake.

Description of Claims

The property consists of eighteen contiguous unpatented

mining claims, Nos. 201101 to 201118 inclusive.

Survey Procedure

The claims have been covered by a grid of control lines

comprising an easterly trending baseline, 1.3 miles long, and 11.2

miles of northerly trending offsets at intervals of 400 feet, a

total of 12.5 mile? of line.

Offsets have been picketed at intervals of 100 feet and

ground magnetometer readings have been taken along these lines at

intervals of 100 feet, and, in some instances, at intervals of 50

feet. Electromagnetic surveys have been run along the lines and

conductor indications traced in detail.

The surveys were performed by C. Parks and I. Charles

between June 1 and June 10, 1970.

Magnetometer Survey

The magnetometer survey was performed using a Barringer

GM 102 nuclear precession magnetometer measuring the total magnetic

field in gammas. Corrections for diurnal drift have been made

using a series of base stations.

Readings are plotted on the accompanying map, Plan SE 397,

and have been contoured at intervals of 100 gammas.

Electromagnetic Survey

The electromagnetic survey was performed using Barringer

LEM 2 vertical field dip angle electromagnetic equipment. Recon­

naissance traverses have been made along the offsets with a sepa­

ration of 400 feet between receiver and transmitter. Conductor

indications detected by these parallel traverses have been traced

in detail by fixed transmitter techniques. Reconnaissance

readings have not been recorded but results of the detailed

tracing are shown on the accompanying plan.

Results

The contoured magnetic map indicates three discontinuous

easterly trending linear positive magnetic anomalies of peak am­

plitudes up to 8,000 gammas above local background. Cause of

these anomalies are unknown but they probably are related to

magnetic metasedimentary horizons.

The electromagnetic survey has indicated six conductors,

three of which are coincident with a long linear magnetic anomaly

through the centre of the block, and the others of which are

associated with other linear magnetic anomalies.
