Placer Deposits

A little placer gold has been found in Peters Creek
and claims have been staked there, but as the values scldom ran
more than four to five colours a pan little work was dono. A
few nuggets valued from 50 cents to $2 have been found in Poters
Creck.

Gold colours have been obtained on panning several
other crecks flowing out of tho Middle River Range, but as yet
sufficicnt values have not been obtained to encourage further work.

Prospecting Possibilitics

As some of the veins exposed in the Topley map-area
lic close to rhyolite intrusives, and as the silver-lead mineral-
ization at Silver Island occurs at the contact of a rhyolite body
with an older body of diorite, it is possible that other mineral
deposits may occur near the contact of some of these bodies of
rhyolite intrusives with older rocks clsewhere in the map-area.

The Taltapin silver-lead property occurs in
Carbonifcrous greenstones near the contact of a granodiorite body, +
The Radio Gold mine is located at the contact of metamorphosed
Carboniferous rocks and a body of granodiorite and diorite. The
Boling property is underlain by Carboniferous greenstones near a
diorite body. On the south slope of Tsitsutl Mountain pyrite and
chalcopyrite have been formed in a band of Carboniferous limestone
near its contact with a granite body. In view of the above facts
the Carboniferous rocks near the borders of the Mesozoic (?) acid
intrusives would appear to be favourable to future prospecting.

The showings of asbestos observed in the peridotite
body on the north slope of Mount Williams indicate that asbestos of
good quality and perhaps in quantity may be present in the serpentinized
peridotites outcropping between Cunningham and Stuart Lakes and in the
Middle River Range. Chromite is another mineral to be looked for when
prospecting the peridotites as it is associated with these rocks.

The platinum group of minerals are associated with basic igneous rocks,
so when panning the streams flowing through areas of these rocks a
careful watch should be kept for indications of this group of minerals.
