Timmins, Ontario

February 1978

R. J. Roussain

A group of eight (8) claims were staked in Cook township by

Amax Potash Limited in April 1977. The claims were acquired as a re

sult of an assessment file search that revealed several apparently un

tested conductors detected in surveys completed by Noranda and Imperial

Oil.

A geological-prospecting survey was carried out over the

claim group in August 1977 to search for outcrops and any evidence of

diamond drilling. No outcrop was found on the property.

INTRODUCTION

A series of VEM and Turam conductors outlined by Noranda and

Imperial Oil respectively, were staked by Amax in April 1977.

In August 1977, a geological-prospecting survey was com

pleted over the property.

This report describes the methods and results of the survey.

LOCATION AND ACCESS

Cook township is located south-east of the village of Ramore,

Highway 11 and the Ontario Northland Railway main line bisect the extreme

south-west corner of the township.

The claim group is situated in that part of Cook township des

cribed as follows: Sh o f Lot 10, Con. II and the Sh of Lot 9, Con. II.

CLAIM MAP

PROJECT 839-01

COOK - l Cook Township l" " k m ile

NTS: 42-A-O

Access to the property is best through the use of the Black

River which traverses the claim group. A boat landing at a bridge on

a concession road near the siding of Wavell is the most convenient.

Alternately, a number of old logging roads that extend south from the

area of the claims can be used as foot routes.

TOPOGRAPHY AND RESOURCES

The area covered by the claims is typified as being over

grown with a thick growth of black spruce and tag alder swamp. A low

ridge extends in a north south direction through claims L-499474 and

L-499479. This ridge is covered with birch and poplar.

Some logging activities were carried out in the past but

were confined for the most part near the river banks.

PREVIOUS HORK

Observed in Field:

Old claim posts and the Noranda grid were observed in the field

as well as the two drill sites reported by Noranda and Imperial Oil.

Scattered blazes and very old picket lines were seen but

could not be related to any work in the assessment files.

Assessment Files:

In 1971-72, Noranda Exploration and Imperial Oil both completed

A.E.M. (Input) surveys in the area and then followed up with ground geo

physical surveys arid diamond drilling. Their efforts appear to have been

carried out simultaneously.

Noranda surveyed their claims with the Crone VEM unit and

magnetics and defined several northwest trending conductors A through

F. Zone "B" was selected for drilling at L16W; 60+OON. The hole in

tersected basic volcanic rocks with minor sulphides and a trace of

chalcopyrite. At 479' a sand seam was intersected and the hole was

lost and abandoned.

No conductor was intersected leaving the anomaly cause un

explained.

Imperial Oil detected an. A.E.M. feature in the NWs of the

Hk of Lot 9, Con. I. which adjoins the present Amax and former Noranda

claim groups. This feature probably represents the southern extension

of the multiple conductive zones as defined by Noranda.

Imperial Oil completed Turam surveys and then attempted to

test the anomaly by diamond drilling. A hole was put down to a depth

of 335' where it was lost in overburden. The Turam anomaly remains un

explained.

Traverses were completed on the central and eastern claims

at 400' intervals in a north-south direction wherever the bush condi

tions allowed. There is extensive flooding in the northern part of the

claim group along a meandering creek.

R. Roussain and Daryl Bremner completed the traverses using

the Noranda grid and Ontario Government 1:15,000 scale air photo number

2.71-4816 43-51. All roads, posts and previous grids were located and

plotted along with physical features.

GE^ERALJSEOLOGY

The rocks underlying the Cook township area are of Archean

age and are composed of intercalated volcanic flow rocks and contem

poraneous sedimentary sequences. Cutting the volcanic rocks are acid

and basic intrusives including granite feldspar porphyry, diorite and

ultramafic dykes and sills.

All of the above units are cut by north south trending dia

base dykes.

Regional mapping indicates that the rocks in the vicinity of

the claim group are acid and basic volcanic flow rocks.

PROPERTY GEOLOGY

No outcrop was observed on the property. A thick cover of

glacial clay and boulder moraine covers the bedrock surface.

Diamond drilling completed by Noranda on claim L-499477

intersected a basic volcanic environment including pillowed andesites

and andesite tuffs.

The magnetic survey carried out by Noranda indicates a con

tact zone striking in a north west direction through the central por

tion of the claim group. On the north side of the contact, magnetic

relief is in the order of 100 - 200 gammas greater than the southern

unit. Two distinct "highs" are located on the eastern boundary area

suggesting the presence of a basic intrusive or other magnetite rich

rock type.

CONCLUSIONS AND RECOMMENDATIONS

There is no outcrop on the property and the conductor is

not exposed.

It is concluded that the rocks underlying the claim group

are volcanic flow rocks with the basic phase intersected in drilling

by Noranda.

Detail lines of long wire horizontal loop survey should be

completed over the VEM conductive axis as defined by Noranda on claims

L-499478 and 1-499477 to determine if they are valid bedrock features

or overburden conductors.
