In the gorge of a small brook entering Pine River South near Table
mountain, four seams of bright coal occur in 90 feet of alternating beds of sand-
stone and shale. These seams in descending order are 6, 8, 24, and 6 inches
thick.? On the lower part of Coal brook, which flows into the east branch of
Pine River South, there are several thin seams, the thickest being 6 inches.
Coal also occurs on the east branch of Pine River South, A seam of lignite
of inferior quality, 12 inches thick, occurs on Brulé river, near its mouth, about
14 miles below Dunvegan.?

' 'F. H. McLearn states that “ Lignite occurs in the upper sandstone member
of the Peace River sandstone, approximately 25 feet below the top at a point
about 10 miles below Peace River. It is also found at a similar horizon near
Peace River on Heart river, etc. Owing to the lateral changes in composition
and thickness this coal horizon can hardly be considered from the standpoint
of large scale operations. However, where locally the coal is of good quality '
and of sufficient thickness and is of marketable value not far (a few feet) from
the face, i.e., all coal removed can be sold, small scale operations may be advisable.

A sample of a layer of lignite 7 inches to 1 foot 2 inches thick, underlain by 44
feet of lignite shale (ash 58-29 per cent) gave the following analysis (Mines
Branch, E. Stansfield, Chief Engineering chemist).

“The greatest thickness of clean lignite measured in the cliffs by the writer
was 1 foot 6 inches. Marketable coal of greater thickness, however, may be
hae present in places.

“The Dunvegan sandstone cannot be looked upon as a coal producer. A
small lignite seam is present in the cliffs below Montagneuse river, but is never
thicker than 6 inches.”
