No. 3 adit (See Figure 11) is at elevation 2,700 feet, its portal being
400 feet south of the portal of the main adit and 250 feet higher. It is
203 feet long, with a 25-foot crosscut to the northeast 40 feet from the
face. For the first 180 feet from the portal, the drift follows a coal seam
that ranges from 3 to 4 feet in width. At 180 feet from the portal a fault
crosses the coal seam at a small angle. The coal is squeezed out along
the fault and its easterly extension has not been located. The coal seam
exposed along the roof of the adit has suffered only minor crushing. It
varies from glistening black to dull graphitic black and is comparatively
firm and clean, with only minor slickensided cross fractures. The follow-
ing analyses of this coal are of channel samples taken across the roof
of the adit by the writer and analysed by the Fuel Testing Division at
Ottawa. Sample No. 109 was taken 18 feet from the portal across 46
inches of coal. Sample No. 110 was collected 155 feet from the portal
where the seam measured 37 inches, but included two beds of bone, 2 and
3 inches thick, respectively, which were excluded from the sample.

At elevation 3,000 feet, and roughly 500 feet south of No. 3 adit,
three groups of coal seams are exposed by a number of open-cuts (See
Figure 11). The first group consists of five seams, which form part of
a section, from north to south, as follows: 30 inches coal, 18 inches rock,
12 inches coal, 6 feet rock, 6 inches coal, 18 inches rock, 6 inches coal,
4 inches rock, and 24 inches coal. These seams strike south 45 degrees
east and dip 55 degrees northeast. The 30-inch seam may be the upward
continuation of the large coal seam in the main adit drift.

In open-cuts 75 feet farther south an 18-inch and a 12-inch coal
seam, with 10 inches of intervening shale, are exposed. Carbonaceous
shale immediately below the 12-inch seam is matted with stems and
other plant remains. The 12-inch coal seam has undergone very little
crushing and is comparatively clean and hard. A channel sample, No.
114, taken across it was analysed by the Fuel Testing Division at Ottawa,
and has the following composition:
