trail from Usk. A switchback trail leads up to the workings from the north fork trail at a point 14 miles above the forks. Two adits were driven in 1928 and 1929, by R. W. Seeley of Seattle, to explore silver-copper deposits. No work has been done since.

The mountain is comprised of a thick assemblage of andesites and basalts, which strike southeast and dip 50 to 60 degrees south. The flows are intruded by several small stocks and tongues of porphyritic erano- diorite.

At elevation 4,800 feet on the summit of the mountain, a sulphide vein of chalcocite and bornite occurs along the contact of two flows strik- ing southeast and dipping 55 degrees southwest. The foot-wall is ereyish brown andesite and the hanging-wall very fine-grained, purplish brown albite andesite, both flows being about 50 feet thick. On the south side of the knife-edge summit, which trends north 80 degrees east, the vein pinches out in less than 30 feet, and on the north side it is hidden 20 feet down the slope by glacial snow and ice. One hundred feet below the summit an adit was driven north 30 degrees east for 220 feet in an endeavour to locate a downward continuation of the vein, but without success. A 6-inch sample taken across the vein in a cut, 10 feet below the summit, assayed: gold, a trace; silver, 74-50 ounces a ton; copper, 24-90 per cent.

About 1,000 feet farther east, at elevation 4,600 feet, an adit drift was run easterly along a sheared zone and quartz vein for about 170 fect. The sheared zone has been traced by test pits along the steep south slope of the mountain for over 1,000 feet. It contains a narrow quartz vein, averaging one foot in width over most of its length. The vein strikes south 80 degrees east and dips 40 degrees north into the mountain. It contains up to 6 per cent of chalcopyrite as irregular impregnations in the quartz and as small lenses. In several pits lenses of chalcopyrite 2 inches wide and 4 feet long were seen in the quartz. An average sample of the mineralized vein quartz from the ore dump assayed: gold, 0:02 ounce a ton; silver, 2:62 ounces a ton; copper, 2-94 per cent.

This group of claims is 5 miles east of Usk, on the north side of Bornite mountain south of Chimdemash creek. The mineral showing is in the Continental basin and is reached from the Chimdemash Creek trail by a well-graded pack-horse trail. No work has been done on the claims since 1914.

At an elevation of 3,900 feet on the west side of Continental basin a strong quartz vein in andesite strikes north and dips west into the mountain slope at 30 degrees. It outcrops close to Continental creek, and from there is exposed in a northerly direction along a steep slope for about 250 feet. In this distance it ranges in width from 8 inches at its southern exposure to 24 inches at its northern exposure. Farther north its continuation is hidden by a talus slope about 1,000 feet wide.

A 45-foot adit has been driven west on the vein near its southern end. The vein narrows from 15 inches at the portal to 5 inches at the face. One
