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.
