Mr. Alex Mosher, President, Chimo Gold Mines Limited, Suite 1000, 11 King Street West, Toronto l, Ontario.

Dear Mr. Mosher:

Submitted herewith is a report on:

ELBO LAKE CLAIMSPATRICIA MINING DIVISION

ONTARIO

Ground geophysical surveys mapped four anomalous zones which may be caused by sulphide mineralization. It is recommended that prospecting be carried out to determine the cause of these anomalous zones and that diamond drilling be consi dered if sulphide are found or if the cause cannot be determined by prospecting.

GENERAL

The Elbo Lake area is located approximately 40 miles

north of Ignace on Highway 599 which provides easy access to

the property. The survey was run over the following mineral

claims:

245540 245541 245542 245543 245544 24-6545

245551 243572 243573

203345 225830

which are held under option by Chimo Gold Mines Limited with

Knappitt Se Smith.

The geology of this area is shown as Geological Map

No. 2169 "Sioux-Lookout - Armstrong Sheet" by the Ontario

Department of Mines. Airborne magnetometer data covering this

area is published in Geophysical Paper 1127-G "Witcomb" by the

Geological Survey of Canada. This area is coded under the

National Topograph Series 52-G-14.

A grid system comprising of 57,600 feet including tie

lines was carried out under the supervision of Mr. K. Kuhnert

of Port Arthur, Ontario, during the latter part of March, 1970.

The baseline trends N 45 0 W with picket lines trending N 45 0 E

at 400 foot intervals. One hundred foot stations were estab

lished on all lines.

MAGNETOMETER SURVEY

The ground magnetometer survey was completed under

the direct supervision of D. G. Wahl, P.Eng., during the period

of April 7 to April 11, 1970. A Barringer GM 102 Magnetometer

with a sensitivity of 10 gammas recorded the total field

magnetic intensities at fifty foot intervals on all lines. In

excess of 900 stations were occupied.

The magnetic data was reduced to a local datum and

adjusted for magnetic diurnal. The data is presented on the

enclosed maps as corrected station values and as a contoured

interpretation of these data.

The rhyolite flows have a relative low uniform

magnetic susceptibility. The andesite flows have a relative

low magnetic susceptibility but are characterized by linear,

trending anomalies marking individual flows.

The porphyritic rocks have moderate magnetic suscep

tibility in the range of 500 to 1000 gammas. The rhyolite

pyroclastic rocks have a high magnetic susceptibility in the

range from 1000 gammas to 1500 gammas.

Associated with the pyroclastic and porphyritic rocks

are strong elongate units having a magnetic susceptibility range

o

from 1000 to 5000 gammas. These elongate units are thought to

be tuffs.

EM SURVEY

The electromagnetic survey was conducted by D. G. Wahl,

P.Eng., during the period from April 7 to April 11, 1970,

employing a Crone Radam VLF EM Survey Unit. This unit measured

the inclination or dip and the total field intensity with a

sensitivity of l 0 of dip and 19& field intensity. The VLF station

used is located at Seattle, Washington, having a frequency of

18.6 KH,. All observations were taken facing west. StationsZ

were occupied at 50 foot intervals on the established grid.

Two very strong conductive zones were mapped lying

within the rhyolite pyroclastic rocks. These anomalous areas

will be discussed in detail in a following section of this

report.

GEOLOGY

The geology as published by the Ontario Department

of Mines was extended and defined by the geophysical surveys

and a compilation of the data is appended.

It appears that a volcanic series ranging in compo

sition from andesitic through rhyolitic containing flows,

5.

C

pyroclastic and porphyritic rocks with associated tuffaceous

bands was folded into an easterly plunging syncline of whichi

the property occupies a portion of the southern limb.

The lowermost member of the volcanic series consists

of andesitic flows which occupies the southern portion of the

property. The porphyritic rocks, probably coarse-grained

quartz feldspar porphyry with tuffaceous interbands, lies atop

the andesite. A small volcanic pile whose center is located

between Line 16+00 West and 20+00 West 250 feet north of the

baseline was formed on these older volcanic rocks. The

pyroclastic rocks and associated tuffs are thought to be

directly related to and a result of this local volcanism. The

youngest member in the volcanic series occupying the central

portion of the syncline is the rhyolitic flows which covers the

northern portion of the property.

No fault systems were detected yet a strange feature

exists between line 48 West and 52 West trending roughly N 45 0 E

which does give the indication of a possible offset of the

pyroclastic rocks. The possibility of this structure being

a dike exists although the major dike pattern in this area

trends north to north northwest.

With the additional information acquired from the

extended survey the cause of this feature should be determined.

o

6.

ANOMALY l

This .anomaly lies within the volcanic tuffs associated

with the pyrclastic rocks and striking roughly- parallel to,

and 300 feet south of the baseline extending between 35 West to

45 West. It is up to 1000 feet long, up to 50 feet wide and

has exceptionally good conductivity with strong magnetic relief.

Attached are sections showing the geophysical responses and

possible causative bodies.

There is strong possibility that this anomalous zone

is caused by sulphide mineralization. It is felt that the

overburden in the vicinity of 3+00 South on line 40+00 West is

in the order of from 10 feet to 15 feet which is in the

feasibility range of bulldozer.

ANOMALY 2

Anomaly 2 lies coincident with the baseline between

39 W and 45 W. This anomaly as in the case of anomaly l is

associated with the volcanic tuffs and pyroclastic rocks.

j Unlike the first anomaly, anomaly 2 appears to be flanking the

tuff horizon. It is up to 600 feet long and up to 50 feet wide

and exhibits similar electromagnetic response as anomaly 1. The

anomaly is flanked to the north by a region of strong magnetict

relief similar to that of anomaly 1. There appears to be an

..JBfHT'"-.'-- mi/Ai:-" '

O

o

7.

old trench in the area of anomaly 2 but due to the snow con

ditions no samples were obtained.

Based on the geophysical response over the area of

anomaly 2, a strong possibility exists of sulphide mineralization

being present.

ANOMALY 3 and 4

These anomalies lie within the pyroclastic rocks

associated with volcanic tuff and are marked by good electro

magnetic response with high associated magnetic relief.

FUTURE WORK

It is strongly recommended that all the anomalous

zones be investigated by surface prospecting and diamond drilling.

A detailed sampling program should be carried out in the area

of the old trench workings consisting of the following:

(1) Random grab samples

(2) Selected grab samples

(3) Latitude and longitude chip sampling.

DIAMOND DRILLING

It is recommended that 1250 feet of diamond drilling

be initiated as summarized in the following table.
