Q. ?4sy

tt INTRODDCTIOM

Geophysical surveys were completed over DIGHEM anomaly

3190A on claims SSM665610, SSM665615 and SSM665616.

LOCATION AND ACCESS

The claims are located approximately 15 miles north of

White River. Access is via helicopter from a base in White

River or by fixed wing aircraft to Dayohessarah Lake. The

grid is approximately 1/2 mile west of the lake.

GEOLOGY

The claims are underlain by northwesterly trending

intermediate to mafic volcanics.

TOPOGRAPHY

The area is relatively flat with a maximum of 25 metres

oL" relief. Outcrop covers approximately 5 to 1(^ of the

area.

METHOD OP SURVEY

Two shoot back lines were run over the area of the

DIGHEM anomaly. When the conductor was located a base line

was cut along the axis and cross lines cut at 200 foot

intervals perpendicular to the axis. An, attempt was made

to trace the anomaly by the vertical loop method and all

lines were read with a magnetometer.

Magnetic readings were corrected for diurnal change by

establishing a base station and checking-in hourly or less.

RESULTS

The anomaly was located on two shootback lines but was

only picked up on one line using the vertical loop mode.

The magnetics are erratic but relatively stable in the

vicinity of the axes.

RECOMMENDATIONS

As some mystery surrounds this conductor, a Pulse EM

survey should be done as an attempt to sort it out.

FLUXGATE MAGNETOMETER

Ihe MF-2 is a completely new concept in vertical force fluxgate magnetometers. These instruments, which are designed for f.ast and accurate mineral ground surveys, are orientation independent, self levelling and require no tripod. The MF-2 combines the electronics and sensor in one compact 3Vj Ib. package. An external dry cell battery pack is provided as standard power source for the instrument. As an-option, recharge able batteries may be provided and housed direct ly in the instrument.With the latest I.C. and F.E.T. circuitry and high precision components, a temperature stability bet ter than 1 gamma per "C is .standard (with .25 gamma on special order) over a range of —40 0 to -f 40*C.The instrument has a built-in hemisphere polarity switch providing two overlapping ranges. For the Northern hemisphere the full range is + 80.000 lo —20,000 gammas, and reversible for the Southern hemisphere.A calibrated feedback system can be provided which makes it possible to determine the total vertical component strength.Measuring resolution, on the 100 gamma scale (optional) is 0.5 gamma, and on the 1000 gamma scale is 5 gammas.The Scintrex MF series of magnetometers have been In use for many years in varied applications, e.g. ground reconnaissance, base station recording and monitoring, study of magnetic properties of rocks, observatory monitoring and recording of both vertical and horizontal components. A high Impedance recorder outlet Is standard.OPTIONAL 8) MF-2G

Tho MF-2G Fluxgate Magnetometer has the

same electronics and specifications as the MF-2, but the sensor is detached and enclosed In a small cylindrical tube which permits it to be oriented and tilted in any desired direction. A 25 foot cable connects the sensor to the Instrument housing. This version is particu larly suitable for the study of the magnetic properties of rocks, and the measurement of magnetic field components of any orientation, etc

b) MF-2GSThe MF-2GS Magnetometer has the same electronics and specifications as toe MF-2 but has two sensors, the enclosed self-levelling sensor of the MF-2 as well as the detached geoprobe of the MF-2G, either one of which can be employed at any one time. Thus, this Instrument can be employed as the standard MF-2 and for the determination of the magnetic properties of rocks, etc.

c) MF-2-100100 gammas and 300 gammas full scale ranges are added to the standard MF-2 and its options.
