these veins, 7 inches in width, is exposed in a rock pit 50 feet west of the
claim post. It is exposed again in a second pit 90 feet southeast of the
claim post, where its width is 3 inches. The vein strikes south 45 degrees
east and dips 75 degrees southwest and has a total length of about 150 feet.
The vein quartz is mineralized with about 3 per cent of sulphide, chiefly
pyrite, chalcopyrite, and tetrahedrite. A 7-inch channel sample taken across
the vein in the first-mentioned pit assayed: gold, 0-02 ounce a ton; silver,
4-38 ounces a ton; copper, 1-24 per cent.

The second vein outcrops in a pit 150 feet northeast of the claim post.
It is exposed for only 20 feet, beyond which it is covered by light drift.
The vein is only 5 inches wide, but the quartz is well mineralized with
chaleocite and tetrahedrite. A 5-inch channel sample across it assayed:
gold, 0-02 ounce a ton; silver, 38-18 ounces a ton; copper, 7-66 per cent.

The foot-wall of the altered quartz diorite dyke is everywhere drift
covered in the vicinity of the veins, so that the possible occurrence of a
vein along it has not been ascertained.

The group comprises three claims staked by R. Moore 20 years ago
on the mountain on the south side of the east fork of Legate creek, about
15 miles by trail southeast of Pacific. The Legate Creek pack-horse trail
follows along the south side of the east fork for a mile and then climbs
by a series of switchbacks to the workings, which are between elevations
of 4,300 and 4,650 feet. The Consolidated Mining and Smelting Company
of Canada did a little work on the claims in 1928 and 1929, but nothing
has been done since.

A series of approximately parallel quartz veins occur near the top of
the mountain in coarsely crystalline albite diorite. The veins occupy faults
or shear zones that strike southeast and dip steeply south.

The upper vein has been traced by a series of test pits for about 600
feet along the north slope of the mountain, at an elevation of 4,600 feet.
It ranges in width from 55 inches at the west end to 6 inches at the east
end, and averages about 2 feet. The strike is north 60 degrees west and
the ‘dip 60 degrees southwest. The vein quartz is bordered on both sides
by several feet of brown, altered diorite. Pyrite, galena, tetrahedrite,
and chalcopyrite are sparsely disseminated throughout the vein quartz,
with occasional rich sections containing up to 5 per cent of sulphide. The
writer collected a 30-inch channel sample across the vein at one of the
richer sections, 100 feet from the west end of the vein, which assayed: gold,
0-02 ounce a ton; silver, 39-28 ounces a ton; copper, 0-36 per cent; lead,
0-82 per cent.

Other veins outcrop on the steep west side (46-degree slope) of the
mountain overlooking the middle fork of Legate creek. “Their upward ex-
tension is terminated by a cross fault striking north and dipping 45 degrees
east at elevation 4,550 feet. One of these veins is best exposed in a ravine
