possibilities of the discovery of large, low-grade deposits.
Mony of the Tertiary granitic intrusives probably are too snall,
too far renoved from the main magma source, and probably were
formed too near the surface to be expected to produce deposits
of economic value. Most of the mineral deposits in the western
part of the Plateau belt are believed to be associated with

Tertiary granitic intrusives. The position of these intrusives

In the eastern part of the Central Interior belt some

‘minerals, the relationships of which are largely unkmown, have

been reported in the following localities: copper volcanics

north of Nechako river 7 miles below Nautley river, and in gneiss

and schist west of Sinkut mountain. Quartz veins are abundant

in some of the schists, especially around Stuart lake and west of
Prince George, and in places these rocks are similar to the gold-

bearing series of Cariboo district, but so far the veins have not

yielded ore and they are more probably a characteristic: of the

rocks than an indication of mineral possibilities. A stibnite

deposit is reported west of Stuart lake and gold deposits are.

said to occur on Sowchea river. No important ore dcposits were

noted near the granitic masses on Sinkut mountain or near

Prince George.
