“A 2-pound sample of the clay was submitted to the Bureau of Mines,
Department of Mines and Resources, Ottawa, and the following report was
received:

Nature of material—a buff-coloured, smooth clay that was found to be
non-caleareous by the dilute hydrochloric acid test.

Water required to temper to stiff plastic state—27 per cent.

Working properties—plastic, works well.

Drying behaviour—satisfactory.

Average drying shrinkage—6 per cent.

“Heonomic Considerations. From the limited amount of testing that
could be carried out on the size of sample submitted, this clay is considered
as having good possibilities for the production of such ceramic products as:
sewer-pipe, pottery, stoneware jugs, bowls, etc., acid-proot brick, buff-
coloured tace brick, and other products for which a stoneware clay is
required. Its refractoriness is too low for it to be of any value as a fireclay.

“The close proximity of clay and fuel in the form of lignite is to be
noted in making an appraisal of the possibilities of either of these mater-
ials.”’

C. O. Hage (1944) reports that:

“Beds of glacial-lake clays are found along Halfway, Beatton, Minaker,
and Prophet Rivers. The deposit on Halfway River is 3 miles east of
Pink Mountain, is 5-0 feet thick, and is varved in beds ranging from 3 to
24 inches in thickness. No samples were analysed, but the clay should be
suitable for making bricks.”

There is an unlimited supply of Cretaceous shales in the Foothills
that might be used in the manufacture of bricks and tile.

COAL DEPOSITS
GENERAL STATEMENT

Large deposits of good quality bituminous coal occur in northeastern
British Columbia in the Gething formation of Lower Cretaceous age. The
deposits are found in the following localities: Peace River Canyon coal area,
Dunlevy Creek-Cust Creek-Butler Ridge area, Carbon Creek coal basin
area, Fisher Creek-Pine River area, Hasler Creek coal area, and Halfway-
Sikanni Chief Rivers area. The Peace River Canyon coalfield is the best
