GEOPHYSICAL SURVEY

The geophysical survey was carried out in the fall of 1951, under

the supervision of Mr* S. L* Spafford, Readings with an Aakania magnetometer

were made at regular intervals on a systematic grid, (see appendix).

INTERPRETATION OF GEOPHYSICAL SURVEY

Magnetic readings range from a base level of about 400 gaomas

(referred to an arbitrary base-level) to 3,500 gammas. The trends of the

readings indicate a southwest-northeast strike.

The nore magnetic zones coloured in brown on the accompanying

map, are interpreted to be due to sill-like intrusives of gabbro, with some

peridotite in the centre of the largest body to the south* Minor iron

formation may be present.

All of the magnetic zones should be investigated in the field,

but the most interesting section is interpreted to lie along the southern

part of the claim group. Two diamond drill holes are reconu-.ended to test

the larger magnetic zone, one near its centre, and the other at the eastern

end where the intrusive may be displaced by a fault* TMs zone lies close

to the property boundary with Taehota Gold Mines Limited.

^*hile one of the objectives is to locate gold-bearing mineral

ization, the southern anomaly zone is recommended particularly for further

investigation, to test the base-metal possibilities.

IKTRODUCTIU,

The Lee Group Ho* 2 under option to Rouandah Gold and Metal B

ia favourably located, but no detailed information about the property is

available* Accordingly a geophysical survey was aiade in the fall of 1951.

LOCATION AND ACCESS

The property is located between the Onaman River and the south

branch of the Onaman River four miles west of the property of Tashota Gold

Mines. The claims may be reached by snowmobile on a winter road 20 miles

from Tashota, Ontario, or in summer by canoe 15 miles from the Onaman River

bridge up the South Onaman River. The land is generally flat and swampy,

with good stands of spruoe, balsam, Jaokpine, poplar and white birch*

GENERAL GEOLOGY

The area is described by Kindlel and a general report on the

property has been made by Hopkins'*

The rooks of the area, whioh are all of Precambrian age, are

similar to those found in the Sturgeon River in Little Long Lac area to the

south. The area in the vicinity of the property is underlain by rooks,

presumably Keewatin in age, whioh include basalt, andesite, some tuffs,

diorite and thin beds of iron formation*

An Algoman batholith lies north and west of the property, and

porphyry dikes have been mapped in this section* Diabase dikes occasionally

intrude the older consolidated rocks of the region.

The ore bodies in the aroa are replacement deposits and nay be

expected to be irregular in shape. Hopkins has noted that "there is apparent

K OF GSQHiYSIGAL SURVEY

Irregular ruai'.iiotio readings were obtained in the northeastern

section of the property northeast of an interpreted fault (see accompanying

oap). The contrast exceeds 10,000 gamins (-6799 to +4075). An east-west

strike of the for:;.at;ion3 is 3Uf,j,c3ted in this zone and. the result* indicate

tho base netal pocsibilities. Before drilling, however, the anomalous sections

of the property should be geologically liiapped ana prospected.

A second drill hole is tentatively suggested to test the anomaly

in the southwestern part of the property. Tho anomaly is across foraational

strike in this section, and is probably duo to local basic intrusives.

KQUANDAH GOLD & METALS LIMITS

INTRODUCTION

The Lee Group Ho. 3 under option to Houandah Gold A: Metals Limited

is favourably located in the Onaman River Area, the scene of considerable

recent aining activity. The present report deals with a magnetometer survey

which was completed in Kay 1952. The group consists of 9 unpatented contiguous

c la ins numbered TB-41278 to 86 inclusive.

LOCATION Alii) ACCESS

The property is located in the nipigon Forest Reserve half a mile west

of the oast Reserve Line opposite mileage 53. It lies about 40 miles northwest

of CJeraldton. The property may be reached by pack trail frccu the South Onaman

River, which is accessible by canoe. A motor road from the trans-Canada high

way at Nezah is being completed. This will simplify the transportation problems

in the area*

GSi&KAL GEOLOGY

The consolidated rocks of the area are a typical early Precambrian

assemblage consisting of Kecwatin-type lavas and Timiskaming-type sodinents

intruded by G oeriea of granitic intrusives and basic intrusives of several

ti t.;oD. The volcanic rocks on tho property are highly sohisted and carbo:iatizod.

Several large porphyry.' dikes cut t\o lavas. Tho ^ouandah Mo. 3 Group lias closo

ECOMOMIO GEOLOGY

Deposits of gold, copper, zinc, lead, and silver are known in a

belt extending ton niloa from the Tashota-Nipigon on the northeast to the

Craibbo (Yfells find) on the southwest. The base netal deposits are largely of

the replacement type. In some oases they contain magnetite and pyrrhotite in

sufficient quantities to make the magnetic nothod effective in the location of

new oro bodies. At scrao of the deposits porphyry dikes appear to have controlled

the deposition of the metallic minerals*

GEOPHYSICAL SURVEY

The geophysical survey was carried out in May 1952 under the super

vision of S. L* Spafford. Headings of vertical magnetic intensity were taken

using an Askania-'type nafpietameter along north-south picket lines*

INTERPRETATION OF GEOPHYSICAL SURVEY

The effictivenesB of the magnetic method in locating mineral deposits

depends either on tho presence of magnetic rdnorals associated with the ore-

ninerals, or on the recognition of structures known to be favourable for ore-

deposition in a particular area. A number of anomalies have been located by the

magnetometer survey. One of these appears to be due to a wido porphyry dike.

Probably other anomalies can be assigned to the same cause* Tho interpretation

of the magnetic data is raade i.iore difficult by the general north-south trend of

the formations parallel to the traverse lines*

It is reccEsnendod that all magnetic anomalies on the property be

3.

examined, both Franz, the standpoint of association with magnetic minerals

and porphyry dikes* It should be possible to determine the causes of most

of the anomalies by stripping or shallow trenching.f
