"conomic Geological Conditions

About 3000 feet south of the area of the present

survey geological condition* favorable for the deposition of

nickel and copper sulfides are found near the south contact

of the large basic mass on this property.

As a result of geophysical surveys, drilling has

located massive sulfides in a number of places along an east-

vest zone more than 5000 feet long. At this time nickel and

copper values are of less than economic grade,

The present survey covers the northern edge of this

basic mass, and was laid out in order to determine if con

ductive sulfide deposits also occur nearby.

THE GEOPHYSICAL

General

Two geophysica^aethodg. are used for this examination,

The Very Low Frequency (VLF) method, made possible by

the development of the RonkaEtt^rgggijej^ is used to indicate

the location of zones of relatively higher conductivity; usually

caused by shearing, faulting, fracturing and conductive sulfide*

in the bedrock.

The accurate recording of the vertical component of

the earth's magnetic field at the surface will show the relative

distribution of magnetic minerals in the underlying bedrock.

This knowledge will assist in the interpretation of the geo

physical data into geological terms and possibilities.

The writer, Douglas Burton, supervised theJyiF

the magnetic field observations .during the course of the

physical exandnation-PJLJ-hiB property,

The VLK Itethod and procedure for Geophysical Prospecting

Many Very Low Frequency (VLF) transmitters are located

all over the world. These transmitters origin&te Morse Code and

pulsed continuous wave carriers. Their particular application

is for world-wide communication with submarines! under conductive

seawater. VLF radiation has.considerable penetration into the

earth.

Page 10: RPT ON VLF AND MAG SUR - PROP OF NICKEL RIM MINES LTD

~ 7 ~ DOUGLAS BURTON. F. ENQ

GEOPHYBICAlr SURVEYS

COBALT. ONT

The radiation is vertically polarized and propagates

radially in straight lines concentrically from, the transmitter.

The radiation is characterized by low path attenuation which is

relatively stable with time,

Changes in the usual propagation pattern of VLF radia

tion are introduced by such factors as land-sea boundaries, and

changes in the ground characteristics. Good conductors in the

earth such as sulfides and graphite cones, and shears and faults

of some considerable dimension, will have a tendency to concen

trate and locally distort VU radiation. Artificial conductors1 " " " * L ' . *

such as pipe lines, fences, electric lines and railroad tracks•' * ' ' " - ' ' f,'-'-'

distort these fields. '•••* - - "' -.' ":- -' " -. *'*- ' : ' -VLF transmissions are most strongly concentrated by

electrically conductive zones with a strike or longitudinal

dimension along the radial path of propagation from each trans

mitter. In order to adequately explore an ftre.it where the strike

of conductive zones nay be at any angle it is advisable to use

two transmitting stations so that the radiation direction is

at right angles in order that the conductive zones may develop

strong anomalous conditions.

The Ronka EKL6 receiver for VIF radiafrien* haa two

directional antenna at right,anslgB,.- It will determine the

dip of the field and the phase difference from point to point

in the area of survey. Usually two transmitting stations arfl-

used for determining these parameters. Readings are usually

GEQPHVSICAL S URVEYS

taken at ICO foot intervals along a profile line crossing

the general geological strike of the area examined. Con-

ductive zones are indicated by anomalous dips of the field

in the vicinity, with a vertical orientation directly over

a conductive zone. When the dips are recorded and plotted

on a map the approximate position of a conductive bod/ is

indicated, and possibly the dip of the conductive zone is

shown.

The Magnetic Survey

The recordings are made by means of on accurate

vertical component Eero balance adjusted to a sensitivity of

ten gammas per scale division.

The magnetic intensity at any point on the surface

will usually differ from the average value for the region.

Anomalous intensities are caused by changes in the magnetic

minerals below. The magnetic susceptibility ( of rocks is

generally accounted for by the contained magnetite although

other magnetic minerals such as pyrrhotite may contribute to

the observed intensity.

This method is used for the direct location of

magnetic minerals such as magnetite. Magnetic surveys may

assist in geological mapping. The plotted results, when

compared with the known geological conditions, frequently

yield information for the solution of geological problems,

especially where rook outcrops are hidden by overburden.

GEOPHYSICAL SURVEYS

COBALT, ONT

Magnetic anomalies are oftwi found associated with forrtational

contacts and structural features. Dikes and faults nay be

located and traced.

Zones of stronger magnetic intensity indicate con

centrations of magnetite and pyrrhotite. These often accompany

valuable non-magnetic mineral concentrations. On the other

hand lower magnetic intensities nay indicate important zones

of alteration where magnetite is changed to non-magnetic

minerals.

THE RESULTS OF THE GEOPHYSICAL SURVEYS

The Maps (numbered 70-72-1. -2 an^ -3)

Accompanying this report are three maps drawn on a

scale of one inch equals 200 feet . On these maps the taped

and picketed north-south lines are shown with their eastHjest

base- and tie-lines^. Lakes, creeks and marked topographic

relief are shown, together with roads and access trails, the

gas pipe line, and mining claim numbers.

Map70-72-l shows the results of the magnetic

examination. The relative magnetic vertical component in

tensity is shown in gammas on the profile lines examined.

Lines of equal intensity are drawn. Areas with less intensity

than 7600 gammas are tinted in red. The contour lines of 9000

gammas and above are colored blue.

In order to avoid continuous repetition in the

mapping of the magnetic results, 50,000 gammas are deducted

from the calculated magnetic intensity.

Maps 70-72-2 and -3 show the results of the VLF

examination from two VLF transmitters with the Konka EML6

receiver. Map 70-72-2 shows the results frcj fl^ Craelc.

The interpretation of the geophysical results are

shown on all of the maps. Fault nones and dikes a&gnetieally

indicated are shown as well as the conductive cones indicated

by the VJJ1' cross-overs.

The locations chosen for exploration are shown on

all of these maps,

The Results of the VLF Surveys

The VLF radiation from

west, and from ^^Sm^^^^

distorted in a few places to indicate conductive tones. V1F

anomalies have been selected for further exploration by drilling.

The electrically conductive gas pipe line on the east

portion of the property distortsy^the VIF field so strongly

that naturally conductive zones that may be in the ground nearby

are completely masked.

The Results of t he Magnetic Survey

The magnetic intensities in the area surveyed varied

from 5000 gammas to 20,000 gammas with an average value of about

8000 gammas. The large variations are caused 'tjy a mss of mag

netic basic rock in the south central portion of the area. The

greater portion of the property has a magnetic variation between

#000 gammas and 8500 gammas indicating weakly inagnetic rooks

such as greywacke and conglomerate, and granite.

ing. The targets selected in the order of their priority are

centered at the following coordinates:

(1) W2600 N550 and west(2) W5500 W)(3} W4700 N2400

During this period, the applicant may apply to the Mining Commissioner for relief if his claims are jeopardized for lack of work or, if he wishes, may file with the Department, normal assessment work breakdowns listing the names of the employees -and the dates of work. The survey would then be re-assessed to determine if higher credits may be allowed under the provisions of subsections 8 and 9 of section 84 of the Mining Act.

If new breakdowns are not submitted, the Performance and Coverage credits are confirmed to the Mining Recorder at the end of the fifteen days.
