The Precambrian slates, quartzites, etc., are cut by massive
dykes of basic type, and show some quartz stringers and veins. The
strata are generally rusty weathering, but mineralization is. represented
on & very small scale. As this’formation is dated as Precambrian, it _
holds possibilities and deserves more attention, especially in the. upper
Toad River Valley and west of Muncho Lake. Trails lead into both OL
these areas. a

The Pennsylvanian (or Permian) chert beds may be correlative
with the Rocky Mountain quartzites of the more southern Rocky Mountains,
in which phosphate deposits occur. The chert may be examined at mile 92
on the Highway. It outcrops in a narrow band, but extends northward
into a hill of considerable size.

Coal

Sandstones and bituminous shales, classed.as Lower Cretaceous
in age, occur between miles 85 and 87. No coal has.yet been found in
them, but they appear to represent the northern extension of the Bull-
head group of Peace River in which valuable deposits of high-grade coal
have been found. ithe) es y

A 3-inch coal seam was seen in later ‘Lower (eoenresvone (Fort
St. John) shale near mile 53, and a 1-foot seam of coal was found near
the top of. ae cin just beneath the Upper Cretaceous be’s on Table
Mountain.

An occurrence of brown lignite on Coal River has been desoribed
above. Masses of drift lignite, collected from the river bars, were
used in heating the nearby army camp. A sample of this lignite was .
analysed by the Bureau of Mines, Department of Mines»and Resources;
Ottawa. The results pretes follows:

The amount of coal accessible cannot be determined without .
extensive field work and drilling. At least 15 feet of lignite, such as
represented by the analysis, outcrops for some 600 yards along the river
bank and for the width of the river flats, or about 300 yards. The _
extent of the basin is about 10 miles by 2 to 3 miles.. The direct dis-
tance from the Highway is estimated at about 6 miles, and road building
along the west side of the stream would involve terracing along high
gravel banks for a part of the distance. A winter road along the. frozen
