0-08 ounce a ton; copper, 13-38 per cent. In 1914, W. M. Brewer collected
a sample here that assayed: “gold, 0-84 ounce; silver, 11-0 ounces; copper,
8-0 per cent.”

No. 2 adit was driven for 130 feet in a direction south 16 degrees east
to intersect the downward extension of the No. 1 vein at an elevation of
1,100 feet. About 70 feet from the portal a 12-inch shear zone with a few
quartz stringers was encountered, but it dips 60 degrees southeast rather
than 40 degrees northwest. At 130 feet from the portal the adit turns at
right angles and continues an additional 60 feet southwest. Fifteen feet
from the face the andesite is cut by a 6-foot dyke of andesine diorite
porphyry striking north.

No. 3 adit is 75 feet distant from and 25 feet below No. 2 adit. It
follows a quartz vein that strikes south 12 degrees east and dips 25 degrees
west. The vein carries a little chalcopyrite and bornite, but is narrow,
ranging from 12 inches at the portal to 3 inches at the face. There it meets
a cross vein that strikes at right angles and dips 40 degrees north. This
vein consists of 8 inches of barren-looking quartz, for the few feet exposed
in a 5-foot cross drift.

A 10-inch channel sample taken 11 feet from the portal assayed: silver,
0-50 ounce a ton; gold, a trace; copper, 0-26 per cent. A sample taken
from the 8-inch vein at the face showed neither gold nor silver.

No. 4 adit, 90 feet to the northwest and at 50 feet lower elevation,
follows a quartz vein which may connect with the vein in No. 3 adit. The
vein strikes south and dips 35 degrees west. The adit is only 12 feet long
and the vein ranges from 14 inches in width at the portal to a few inches
at the face. Neither vein nor schistose andesite wall-rock shows sign of
mineralization.

Half a mile farther east, at an elevation of 2,100 feet, a quartz-albite
dyke cutting massive andesitic lavas strikes southeast across the bed of a
small mountain stream. West of the dyke the andesite is mineralized with
sparsely distributed chalcocite and chalcopyrite over a width of 100 feet.
The sulphides occur along fine joint fissures and as replacements of the
andesite near the joints. Stripping and trenching done here eight years
ago failed to reveal commercial grades of copper ore.

Madden Claim (24)

Reference: Ann. Rept., Minister of Mines, B.C.: 1914, p. 135.

This claim is on Chimdemash creek 2 miles east of Skeena river. It
was first staked in 1894 by Captain Madden, pioneer placer miner, who
drove a 20-foot adit, at elevation 500 feet, into the south bank of the creek
along a quartz vein. The vein outcrops at the water’s edge in andesitic
voleanics and is exposed by natural agencies for 75 feet in a southeast
direction up a steep bank, above which bedrock is drift covered. The
vein is very sparsely mineralized, containing only a little chaleocite and
specularite. A 16-inch channel sample taken across the vein at the entrance
to the adit assayed: gold, a trace; silver, 0:02 ounce aton. Another 16-inch
channel sample taken across the vein at 50 feet higher elevation assayed:
gold, a trace; silver, 0:15 ounce a ton.
