southern states, sold for 30 to 40 cents per pound for 14 by 2-inch sheets,
for $1.30 to $1.55 for 3 by 3-inch sheets, $3 to $3.80 for 6 by 6-inch sheets,
and $5.65 to $7.50 per pound for 8 by 10-inch sheets. The price varied
according to whether the mica was spotted or clear. Slightly stained
Indian muscovite sold at about the average price of the United States
product.

A hasty visit was made‘ to an occurrence of muscovite mica situated
in the Clearwater (or Cariboo) mountain (Figure 2. locality 19). This
property, owned by F. D. Foster, lies on one of the western ridges of the
range between Clearwater and Crooked lakes, about 15 to 20 miles from
the east end of Canim lake, in a direction north 2 degrees west, magnetic
(approximately north 26 degrees east true azimuth). The location as
given on the index map with this report may be in error as much as several
miles. The elevation as determined by aneroid in unsettled weather, is
6,450 feet above sea-level. The claims were reached by two and a half
days of hard riding from the west end of Canim lake over an Indian hunting
trail. From the east end the trip would occupy one and a half days.

The mica occurs in a series of parallel pegmatite dykes lying in mica
schist. The easterly dyke strikes east 53 degrees south, dips 54 degrees
to the northeast, and is ‘from 10 to 20 feet wide; its outcrop could be traced
for about 500 feet. Other dykes lying parallel to and within a few hundred
feet of each other are from 5 to 25 feet wide and form a belt that was
traced a distance of about three-quarters of a mile. One opening is 20
by 15 by 8 to 10 feet deep. The mica crystals occur in bands in the pegma-
tite, the bands being up to a foot in width. The individual crystals seen
varied from 6 inches to 12 inches in greatest dimension, through a distance
of about 100 feet along the length of the easterly dyke. An outcrop of
one of the dykes contained crystals 6 inches in diameter, but the diameter
in general wasrarely more than 3 inches and the greater part of the out-
crop was barren. The thickness of the crystals was as a rule about one-
third of the greatest dimension of the leaves. The crystals are in many
cases wedge-shaped, books of leaves overlapping and ‘‘feathering out.”
A considerable amount of so-called ‘‘A”’ mica occurs, in which only a small
part of the sheets is of any commercial value. The best crystals were
perhaps removed from the open-cut before the writer’s visit. The mica
seen was white or nearly colourless with a greenish to amber tint. A
great many crystals are stained yellowish by surface weathering.

The condition of the mica crystals at the surface, indicating that
they have been subjected to pressure and contortion after their formation,
is to be expected throughout the deposit, but the yellow stain on the
mineral is likely to disappear in depth.

The dykes cross a nearly flat-topped ridge about half a mile wide,
from both sides of which the land slopes steeply for several hundred feet.
The dykes were not followed down the sides of the ridge for any great
distance. If development is ever undertaken both depth and drainage
~ could be obtained by a tunnel driven from the southeast slope of the ridge.
The outcrops are above timber-line, but mine timber can be obtained
within a short distance.

An expenditure of $600 to $800 would be necessary to construct a
first class pack trail from the property to the east end of Canim lake.
This trail could be travelled by heavily loaded pack trains during August
