zinc, 0-25 per cent; antimony, 0-98 per cent; arsenic, 0-12 per cent.
Kighty feet northeast of the crosscut, a raise is driven up 175 feet to the
surface. At the foot of the raise and continuing for 75 feet to the northeast,
the vein ranges from 3 to 12 inches in width and the quartz gangue is well
mineralized with jamesonite. A typical 4-inch channel sample taken across
the vein at the foot of the raise, consisting of about 60 per cent sulphide
and 40 per cent quartz, assayed: gold, a trace; silver, 14:67 ounces a ton;
lead, 6-90 per cent; zinc, 9-75 per cent; antimony, 4:01 per cent; arsenic,
0-05 per cent. For 100 feet at its northeast end, the vein is very sparsely
mineralized and in a number of places the fault fissure contains no vein
filling whatsoever. Two hundred feet north of the raise, the vein splits
and one branch, consisting of 12 inches of sheared tuff veined with quartz
and siderite, passes into the north wall of the drift. The east branch is
drifted along, but ends suddenly where the drift enters a body of
granodiorite.

The drift continues 60 feet northeast from the end of No. 2 vein
through granodiorite, then follows No. 3 vein for 120 feet along the fault
contact between granodiorite on the northwest and altered tuff on the
southeast to where the vein ends abruptly against a strong cross fault and
sheared zone that strikes north and dips 75 degrees east. The vein has an
average width of 6 inches and is generally only sparsely mineralized,
but in several places carries from 3 to 5 per cent of jamesonite and pyrite.

No. 4 vein lies approximately 800 feet northeast of the main vein at
elevation 2,225 feet. It is enclosed in a small body of fine-grained,
recrystallized, tuffaceous rock. The vein is 100 feet long and ranges from
4 feet in width at its southwest end to 4 inches in width at its northeast end.
It is developed by a 50-foot shaft that follows the vein down on an incline
of 65 degrees. Twenty feet south of the shaft the vein ends abruptly -
against a cross fault that brings in a V-shaped wedge of the main body of
granodiorite along the strike of the vein. The quartz gangue is well
mineralized in the wide part of the vein south of the shaft and for 40 feet
north of the shaft, and carries up to 30 per cent of jamesonite, sphalerite,
galena, and tetrahedrite. An 18-inch channel sample taken across the
vein 12 feet northeast of the shaft assayed: gold, 0:01 ounce a ton; silver,
4-19 ounces a ton; lead, 8-38 per cent; zinc, 1-73 per cent; antimony,
3°84 per cent; bismuth, nil; arsenic, 0-87 per cent.

There are a few tons of hand-sorted ore piled on the rock dump at
the main adit. A hand specimen of this ore, consisting of banded, finely
crystalline jamesonite and sphalerite with fine stringers of argentite
replacing the jamesonite, assayed: gold, 0-015 ounce a ton; silver, 116-06
ounces a ton; lead, 22-33 per cent; zinc, 7-98 per cent; arsenic, 0-61 per
cent; antimony, 11-54 per cent; bismuth, nil; cobalt, 0-21 per cent.
Another sample, composed of 50 per cent grey quartz replaced by
jamesonite and with a few nodules of sphalerite, assayed: gold, 0-01 ounce
a ton; silver, 49-26 ounces a ton; lead, 11-45 per cent; zinc, 3-40 per cent;
arsenic, 0:06 per cent; antimony, 6-45 per cent; bismuth, nil; cobalt,
0-21 per cent.
