south 60 degrees east and dips 30 degrees southwest. A channel sample
taken here gave negative values in gold and silver. Another quartz vein is
exposed 600 feet north along the steep edge of the cirque, but is inaccessible
due to the steep slope.

A 6-foot quartz-albite dyke with a 12-inch quartz vein lying along its
upper contact is exposed on the north side of the cirque at elevation 4,500
feet. Vein and dyke strike south 20 degrees west and dip 30 degrees north-
west into the hill-side. They are exposed on the east side of a narrow draw,
southwest of which their projection is covered by a talus slope. To the
northeast the dyke pinches out in about 100 feet, but the vein continues
beyond the dyke an additional 100 feet before pinching. The andesite
above the vein is rusty brown over a width of several feet, particularly
where the vein rests on the dyke, and where alteration is most pronounced
the andesite is cut by a stockwork of small 2-inch quartz veinlets. The
vein quartz contains up to 1 per cent of chalcocite irregularly distributed.
No work has been done on this showing.

There are several other small quartz veins at a higher elevation north
of the cirque.

The Toulon group of Crown-granted mineral claims is 3 miles east of
Usk on the mountain slope on the south side of Chimdemash creek, and is
reached by a branch from the Chimdemash Creek trail. These claims were
first located in May 1899, and three short exploratory adits were driven
between 1900 and 1910 by the Bornite Mining Company of Portland,
‘Oregon.

At an elevation of 1,200 feet an adit (No. 1 adit) has been driven 80
feet along a quartz vein (No. 1 vein) in schistose andesite. The vein occurs
along a fault of small displacement that lies parallel to the schistosity of
the andesite. Its strike is approximately south 60 degrees west and the
dip is 40 degrees northwest. The vein has an average width of 3 feet, but
a lens-like nature is apparent at the portal where an initial vein width of
5 feet pinches to 5 inches only 20 feet above the portal. The quartz carries
about 1 per cent of sulphide, chiefly chalcocite and chalcopyrite. The vein
is cut by two faults, one 40 feet and the other 80 feet from the portal. The
first shifts the vein a few feet northwest, and at the second one the vein
disappears. It appears to have been downfaulted. The adit was continued
beyond this second fault an additional 60 feet in a direction south 15
degrees west, but did not locate the faulted part of the vein. There is a 6-
or 8-foot dyke of andesine diorite porphyry at the face of the adit and a
5-foot dyke of fine-grained diorite 35 feet from the face. Both dykes strike
north.

A 31-inch channel sample taken across the vein 70 feet from the portal
assayed: silver, 2-16 ounces a ton; gold, 0-02 ounce a ton; copper, 1°32 per
cent. A sample of quartz containing bornite and chalcopyrite was picked
from the dump at the portal and assayed: silver, 17-52 ounces a ton; gold,
