Hew Fortune Mines Limited, 22 Toronto Street, Toronto, Ontario.

Gentlemen*

The following report describes the electrical

resistivity surrey conducted over twenty-six Mining claims

held by New Fortune Mines Limited and located four miles east

of Manitouwadge Lake, District of Thunder Bay, Port Arthur

Mining Division, Ontario*

The survey was conducted by Qao-Teehnioal Development

Company Limited during the period from February 7th to March 7th,

19514.* The results obtained on this survey are depicted on

Plan Ho. l accompanying this report*

Summary and Recommendations

The survey indicated three fairly well defined north

east trending linear zones showing relatively lower resistivity

and which have been interpreted as representing shearing or

faulting. Two possible geological contacts were alio suggested

by the electrical resistivity results. Throe anomalous sones

suggesting possible sulphide mineralisation are identified on

the accompanying plan by the letter,* - *A\ "B* and "C". Two of v~~- -' . i - -

these cones are associated with interpreted shearing or faulting

and the third with an Interpreted geological contact*

It is recommended that the next step in the exploration

of this claims group be confined to geological mapping and

detailed prospecting to be followed by diamond drilling where

deemed necessary*

The property of New Fortune Mine* Limited discussed

in this report consists of 26 mining claims located in the

Manitouwadge area, District of Thunder Bay* Ontario. The claims

form an almost rectangular block approximately one and a quarter

miles square and are further described as t

Claims numbered T. B. 14-7968 to T. B* 1^.8013 Inclusive.

The southwest corner of the claims group is roughly fc alio

north of Mileage Post 88 on the Regional Bast-West base lino.

Location and Access

The Manitouwadge Lake area la located approximately

65 airline miles southeast of Geraldton, Ontario and 1*0 airline

miles northeast of Heron Bay. The area is reached by air from

either of the two points mentioned above and various airway

companies operate chartered flights Into Manitouwadge Lake as

well as other small lakes in the general vicinity. Helicopter

service is also available and is very useful for reaching properties

where there are no lakes suitable for providing landing facilities

for standard aircraft.

A truck road constructed by companies engaged in

lumbering in the general area extends from Stevens, a point

on the Canadian National Railway, south to Camp 12 located la

the west part of the Manitouwadge Lake area mining camp. Several

bush roads service the immediate area around Camp 12 and ara suit

able for truck travel. The distance from Stevens to Camp 12 i*

approximately 30 miles. A winter road also extends north from

Helmo on the Canadian Pacific Railway and services legging camps

in the south part of the general Manitouwadge area.

Topography

The topography of the Hew Fortune Mine* Limited claim*

group is fairly rugged and consist* of low rook outer*? hills

timbered with spruce and Jackpine but whioh have beei in part

burned over in recent years. Conaiderable windfalls U* the ve)*t-t-s* .f l '

ern half of the claims group make* line cutting and traversing

quite difficult. However in the eastern part the teptfraphyiIs

lower with the result that the timber has been damaged very

little by bush fires. V ;v ~

A small lake known as Oauginopikima Lake ia Jtoated

just off the southwest corner of the claims group. A Jwminent•' " 1T' ,: '" " - n f*

Mines and is shown on Map 1*1 j "Heron Bay and White L*J|f Area"

w However, without any geological iaformation it i*

generally possible to differentiate between banded rook* sueh

as volcanics, sediments or gneiss snd large bodies of massive

intrusives, due to the difference of electrical oonduotlvity

between the various flows or beds. Strike trends, folding,

etc., are therefore readily picked up. In some oases, rook

contacts may be inferred.

Shear or fracture zones are relatively better con

ductors due to their higher water eon tent* Where extreme low

resistivity values are found, graphite or sulphides ir* indi

cated. Graphite is found in schist or shear zones or sedi

mentary horizons, which are shown by electrical Methods as,

generally, narrow low linear trends* Unfortunately, fro*

the point of view of interpretation, sulphides nay be present

with the graphite or may occur in shear zones giving similar

low linears.

Interpretation of Resistivity Results

The results of the electrical, resistivity survey

conducted over the property of Hew Fortune Mines Limited and

discussed herein is depicted on Plan No. l accompanying thin

report. The resistivity readings over the entire area varied

within a fairly narrow range but sufficient variations wore;

obtained to suggest significant structural features, the

contour pattern for the most part strikes in a north-east

direction which conforms with the general geological strike

of the area. Three quite well defined linear trends 0onform-

ing to this strike have been Interpreted as representing fault

ing or shearing. The location of these f suits are shown on

the accompanying plan.

A variation between the reading* obtained In the

extreme east part of the property aa well as In th* northwest

corner y as compared to those obtained over the regaining part

of the claims group, suggests geological contacts whieh are

shown on Plan No. l by heavy dash lines. A strong anomalous

condition indicated by quite low resistivity readings and

identified as the "A" anomaly occurs In the southeast oorner

of the claims group. This anomaly strikes northwest and is

normal to the regional strike in tile area* The association

of this anomaly with the interpreted geological contact sug

gests that the low readings could represent a oontaot sulphide

deposit.

A second small anomaly occurs immediately south from

the east end of the north base line and is associated with an

interpreted fault or shear zone. ThlB anomalous zone Is ref-1 : ' ."- ~" - -*;!* ' '

erred to on the accompanying plan as the "B" anomaly. A some

what similar structure referred to as th* "C" anomaly la

located near the north end of lines 28B and 32E and is also

associated with an interpreted shear or fault cone. Both of

these anomalies are important as possible s one s of stt&phlde

mineralization* j

Several other minor low resistivity *ones, for the

most part confined to one reading, were obtained Iforoughout

the surveyed area,

A general reconnaissance of the property during the

course of the survey indicated a considerable amount of rock

outcrop so that it may be possible to investigate some of

Survey Data

An electrical resistivity survey waa oonduoted oTar

the property of New Fortune Mines Limited located in th*

Manitouwadge Lake area, Diatrict of Thunder Bay, Port Arthur

Mining Division, Ontario.

The survey was conducted by Qeo-Teohnlcal Development

Company Limited during the period from February 7th to March

7th, 19514-f a nd the results are shown on Plan Mo. l accoiapanying

this report.

Two ea st-we s t baae lines war* eatablished, one nev

the south boundary and the other through the central portion

of the property* North-south traverse Unas were t or ne d of f

at 1^.00 foot intervals from these base lines. A lino waa ex

tended north from Mileage Post 86 on the regional east-west

base line and this waa established aa Lin* 0+00 on the Haw

Fortune Mines Limited property. The diatanoa from Mileage

Post 88 to the south baae line on the claims group vaa fount

to be 2,510 feet. The traverse linea were out during t h*

winter in heavy anow oonditiona ao that considerable bruah

and deadfalls will have to be removed to make theae iinea

amenable to summer traveraing.

Electrical resistivity readinga wore taken at 50

foot intervals along the north-aouth picket linea. These read

ings are shown on Plan Nn . l to the weat of t ho traverse linea
