SSM 76690 to SSM 76707 inclusive (18 claims)

LOCATION

The property is situated in the northeast quadrant of Striker Township

of the Sault Ste. Marie Mining Division of Ontario. The group abuts

the eastern boundary of the Township with Long Township and extends

from the north shore of Lake Lauzon to within two claim lengths of

the Township's north boundary.

ACCESS

The property is readily accessible from Sudbury or Sault Ste. Marie

via Trans-Canada Highway #17 to villages of cither Algoma Mills or

Blind River. From village of Algoma Mills, access is by boat across

Lake Lauzon, a matter of only seven miles. From village of Blind River,

access is via Highway #555 to McGiverin Lake and then a bush walk for

about two miles to the north-west corner of the property. Suvibury and

Sault Ste. Marie are both served by Air Canada and Canadian Pacifi:

Railways.

\P-.-* '. . -. *

Hydro electric power is available from the Ontario Hydro grid which

supplies the Sudbury-Sault Ste. Marie-Blind River area.

Timber and other building materials are available locally.

Transport via Highway #17, the Canadian Pacific Railway and/or Air

Canada to Sudbury or Sault Ste. Marie is no problem.

An old lumber road trending north-east passes through the property.

It has been obscured by later beaver work and is overgrown at places.

On the accompanying geological and magnetometer survey maps, the

road has been shown by double dashed lines where obvious and by a

single dashed line interspersed with question marks where flooded or

too overgrown to recognize.

HISTORY

The general area of the property has been prospected for copper over

many years and for uranium during the 1953-1956 era. Some of the

drilling done in this general area is inconclusive as a fe\v of the drill

holes failed to reach the basement. The location of the earlier diamond

drill holes is shown on the attached property map and the drilling da:a

2. Gwillim Lake Gold Mines Ltd., drilled a hole in 1955 to a

depth of 830' in now claim #SSM 80991. The hole passed

through quartzites up to a depth of 267' and between 267' and

823' it ran through diabase. From 823* onwards the hole was in

hornblende granite (basement) but no radioactive conglomerates

were encountered.

3. Fitzpatrick Uranium Mines drilled seven holes in now claim

HSSM 76697 in 1955. All the holes were very shallow (ranged

in depth from 25' to 59") and ended in quartzite.

TOPOGRAPHY

The relief of the country is fairly high and a scarp and dip slope topography

prevails in the sediments. The drainage is controlled by the geology,

creeks flow either along the strike or along the weak zones, i. e. contart

zones. The diabase dykes of the Keweenav.ar. type are less resistant to

erosion and usually form small stream channels. There has been fairly

Both coniferous and deciduous trees are common. A lot of forest cover "-- 1 1

has been destroyed by previous forest fires and there is practically no

soil over the quartzite areas.

LINE CUTTING

Line cutting was done on the property during the month of November, 1967

and a total of 46 miles of lines were cut. Three major east-west base

lines were necessary and cross lines were cut north-south from the

base lines at 300 foot intervals.

GENERAL GEOLOGY

The property lies on the southern limb of Chiblow anticline and is

underlain by a thick (about 500') gabbro body in the eastern part and by

Huronian sediments belonging to Lower and Middle Mississagi Formations

in the western part. In the north eastern part of the property Archean

basement rocks of granitic to granodioritic composition outcrop. These

formations are cut by a number of thin east-\vest running diabase dykes.

A vertical fault of no significant throw runs cast-west in the middle of

the property. Following is a brief description of the formations h

chronological order.

Nipissing Diabase

The gabbro sill is about 500" thick and covers about 307r of the map area.

At its contact with quartzites it shows a chilled edge. The body is almost

barren and only at one place (Line 18W. 18N) slight traces of sulphide

mineralization were observed.

Lower and Middle Mississagi Formations

Middle Mississagi Formation outcrops in the western part of the area and

is represented by arkosic quartzites and interbedded argillltes. Lower

Mississagi Formation outcrops in the central and north-west part of the

property and is represented by pink to light colored quartzites and light

greenish arkosic quartzites. The quartzites arc medium to fine grained

and fairly well sorted. The sediments are frequently cross bedded and

show well developed mega-ripple marks, which suggest north westerlyt

current directions. At the contact with Nipissing Diabase the quartzite*

arc slightly bleached and show slich*. concent rations of magnetite anrl

othor mafic minerals.

Magnetometer Survey

A magnetic survey using a Sharpe Fluxgate magnetometer MJ

carried out during November, 1967. Magnetometer readings•: ; itaken both on base lines and cross lines at 100* intervals. Technical

details of the instrument can be found in Appendix "A".

Discussion of the Magnetometer Survey Results

A base control station arbitrarily assigned a magnetic value of 1500

gammas was established at HOON, 33+50E and all the readings were

adjusted to it. Ir. general, the quartzites and arkosic quartzites produce

fairly constant magnetic susceptibility but higher readings are obtained

on the diabase body. Some of the highs in the diabase may be attributed

to concentration of magnetite in the diabase, other high readings occur

on the tops of ridges where tile soil cover is minimum. Higher magnetic

readings were also obtained in the stream channels, this is probably

due to concentration of magnetite in the sand in the stream bed.

Discussion of Scintillometer Results

A scintillometer traverse \\as run following the old road and then along

Line 6W from base line 39 + 60N. The instrument used was a S. R. A. T.

scintillometer of S. P. P. 2. NF type. Usuall-- very low counts were

obtained on the sediments but some of the higher readings correspond

to more arkosic and sericitic bands in the quartzite.

CONCLUSIONS-- :

The results of the geological survey indicate that the general picture

of rock type distribution as shown in the Ontario Department of Mines

P304 and Compilation Series 2108 is quite accurate. The detailed

geological map accompanying this report shows the detail as mapped.

The magnetometer survey suggests no unexpected complications relative

to intrusives with the readings being generally rather uniform.

The diamond drilling carried out by earlier exploration efforts give

inconclusive results in view of either their local and/or the failure to

penetrate to sufficient depth.

In view of the presently known geological data, it would appear that the

obvious location for any exploratory drilling to cross section the favorable

lower Mississagi Sediments in the vicinity of the basement complex,

would be from the middle Mississagi outcrop area on the south and west

part of the claim group.

on claim #SSM 76690 with actual collar location dependent on local

topography. It would be advisable to provide for a minimum of three

holes with any decision relative to the second and third drill dependent

on the data resulting from No. 1. These holes should reach basement

at approximately 1500 feet, thus three holes would involve a total or

an estimated 4500 feet of drilling.
