LOCATION

Noranda Exploration Co. Ltd., staked fourteen claims

TB 277354 to TB 277367 in Horne Township, the Thunder Bay

Mining Division. The Weigand River passes through the north

west claims.

ACCESSIBILITY

The claim group can be easily reached by truck. About

26 miles west of Thunder Bay on the 11A 17A Highway, the Glen-

water Road cuts off to the south and along this road the pro

perty can be located. The claim group is about 6 miles from

the Highway turn off.

LINECUTTING

The baseline was cut on an azimuth of 135 in accordance

with what the general strike is considered to be.

Parallel lines were cut perpendicular to this at spacings

of 400 feet. All the lines are picketed every 100 feet.

There is a total of BJJLjriiJLe-^,oJL--LJ-ii-e- C-U-L-

GENERAL GEOLOGY

The main rock types are extrusives in the form of tuffs,

rhyolites, andesites, breccias and agglomerates. Iron formation

is also present in two lineations striking generally N.60 0 W.

Along the south boundary there are rhyolites with some

local shearing. To the north near the #2 baseline the rhyolite

blends into an acidic tuff which has local brecciation. To the

east the rhyolites predominate, but they become more ferrugenous.

North of the second baseline there are large low outcrops

of tuffaceous agglomerates and rhyolite,

ELECTROMAGNETIC SURVEY

PURPOSE

To determine whether there is any sulphide mineralization.

COMPANY CONDUCTING THE SURVEY

Geophysical operators employed by Noranda Exploration Co.,

Ltd., did the survey under supervision of Peter G. Cooper,

Geophysicist, who planned and is responsible for the survey,

INSTRUMENT & SENSITIVITY

The Electromagnetic survey was carried out using the

* This unit is manufactured

by Crone Geophysic's Ltd., for Noranda Exploration Co. Ltd.,

under Patent No. 63156.

Survey data is obtained by a two man crew. Each man is

equipped with a coil capable of receiving and transmitting, an

amplifier, earphones, and a power supply of three 6 volt bat

teries. The crew uses the "in line shootback" method of sur

veying. One man transmits while the other man receives, and

then they reverse the procedure at the same station. The trans

mitter has an output of 5 watts, and it operates at frequencies

of 1800 Hz and 480 Hz.

The magnetic field caused by an alternating current in

the transmitting coil induces an alternating current into any

conductive medium within the range of the magnetic field. The

conductive medium emits its own magnetic field (secondary mag

netic field), and the combination of these two fields produces

a resultant magnetic field. When the plane of the receiving

coil is positioned in the direction of the resultant field,

there is a minimal amount of current induced into the coil,

and an audial null is noticeable in the earphones. A dip angle

is read from a clinometer when the receiving coil is in this

position. After the two men have reversed this procedure and

they each have taken a reading at the same station, the readings

are added together to obtain a resultant dip angle. When the

readings cancel each other out and the resultant dip angle is

zero, then there is not any subsurface conductivity. But when

the resultant dip angle is ;f3 or greater then an anomaly exists

and detailed readings are taken. This shootback method helps

to eliminate effects due to topographical relief and coil mis-

orientations. The readings are plotted always at the "chief's

position" which is either to the north or east of the helper

depending on the direction of the lines.

RESULTS ^ DISCUSSION

The claim group was staked to include nine airborne con

ductors. It is quite possible that we do not have all of these

conductors particularly the six channel anomalies recorded in

the western portion of the claim group.

The J.E.M. survey recorded an anomaly on all but one line

on this property. Unfortunately the western half of the pro

perty is covered with a thick layer of conductive overburden

which is disguising if not completely masking the effects of

a true conductor. The poor frequency ratios and the noisey

nulls are inductive of the terrain found on this portion of the

property. From line 20SE to line 36SE the anomalous readings

are due to conductive overburden and to small streams. This is

also true of the three channel airborne anomalies recorded in

this area. From 12SE to the west and north the overburden is

masking some very strong airborne anomalies. Several vertical

loop set ups were made; however nothing was found. Some of

these anomalies may be off the property to the west. We will

do a Radem search for these anomalies and then check our find

ings with the vertical loop.

From line 40Se there are several conductive axial trends

and isolated conductors but only two of these have any interest,

On line 40SE at 14 4- DON we pick up a stream which runs north

west to south east. This same stream gave a J.E.M. indication

on line 44SE at 17 + 3 5N. The stream then turns and runs para

llel to the 19 + DON tie line and continues off the property.

A conductor of interest starts on line 40SE at 25 -*- OON.

and runs parallel to strike over to line 60SE. Due to several

reasons the J.E.M. does not have distinct crossovers and the

axial trend does not appear continuous over the complete length

such as on 52SE and 56SE; however the Radem carries the con

ductor off the east end of the property. This conductor para

llels the high magnetic anomaly, but just to the north. The

second conductor of interest is on the top end of line 56SE.

Both the J.E.M. and Radem picked this anomaly up and it may

very well extend to the east off the property. The rock here

is a chert, but there is not any indication of a conductor.

MAGNETIC SURVEY

The magnetometer survey was conducted at the same time

as the E.M. with equally qualified personnel using a

Fluxgate M

The same grid was used with readings everyllOO feet, this

being reduced to 50 foot readings over anomalous areas.

The idea of the survey was to give additional information

to the E.M. survey.

RESULTS 6-jnSCUSSIQN

The airborne survey indicated two magnetic areas on the

claim group, and this is what the ground survey found. The

first anomaly is on the bottom aid of lines 32SE, 36Se and 40SE.

This area is well covered with overburden and we have no idea

what is the cause of this anomaly.

The second magnetic anomaly is in a linear belt of sedi

ments stretching from line 28SE around 21 * OON. over to line

60Se. There is a strong concentration of iron in many places

in this belt.

CONCLUSION

There are a few additional checks to be made on this pro

perty and in particular the locating of the six channel anom

alies on the west end. Many of the other anomalies on this

property are not of significant interest to do more work on

them * Submitted by,

it will qualify for a credit of 40 assessment work days for each claim so covered. It will not be necessary for the applicant to furnish any data or breakdown concerning the persons employed in the survey except for the names and addresses of those in charge of the various phases (linecutting contractor, etc.). It will be assumed that the required number of man days were spent in producing the survey to qualify for the specified credit.

i * Each additional ground geophysical survey using the same grid system and otherwise

meeting these requirements will qualify for an assessment work credit of 20 days.

A geological survey using the same grid system, and meeting the requirements for submission of geological surveys for maximum credits will qualify for an assessment work credit of 20 days. If line cutting has not previously been reported with any other survey and is reported in conjunction with the geological survey a credit of 40 days per claim will be allowed for the survey.

Similarly, a geochemical survey using the same grid system with the average number of collected samples per claim being not less than 40 samples, and meeting the requirements for the submission of geochemical surveys for maximum credits, will qualify for an assessment work credit of 20 days. If line cutting has not previously been reported with any other survey and is reported in conjunction with the geochemical survey a credit of 40 days per claim will be allowed for the survey.

Credits for partial coverage or for surveys not meeting requirements for full credit will be granted on a pro-rata basis.

If the credits are reduced for any reason, a fifteen day Notice of Intent will be issued. 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.
