of jamesonite, sphalerite, galena, and tetrahedrite. The vein is stoped
out above this level for 40 feet along the vein, beginning 65 feet north of
the shaft. Along the surface the vein ranges from 1 to 3 feet in width
and carries disseminated sulphides, with occasional narrow seams of high
sulphide content within the wider vein. In a rock cut 45 feet north of
the shaft the vein consists of 16 inches of vein quartz with a 4-inch seam
near its centre, rich in sulphides. A sample from the 4-inch seam assayed:
gold, 0-01 ounce a ton; silver, 38-6 ounces a ton; lead, 7-24 per cent;
zinc, 15:04 per cent; antimony, 0:25 per cent; arsenic, 0-14 per cent.
In a pit 30 feet farther northeast the vein carries about 3 per cent of
sulphides throughout its width of 30 inches, and there is in addition a
central 3-inch sulphide seam. In the most northerly pit, 180 feet north
of the 38-foot shaft, the vein consists of about 50 per cent quartz and
50 per cent brecciated, altered, tuffaceous wall-rock, containing about
5 per cent of sulphides. A 30-inch channel sample taken across the vein
in this pit assayed: gold, 0:01 ounce a ton; silver, 1-73 ounces a ton;
lead, 0-41 per cent; zinc, 0-56 per cent; antimony, 0-25 per cent; arsenic,
2-37 per cent.

In the long crosscut adit driven at elevation 2,000 feet, the main vein
is intersected at 450 feet from the portal and a drift runs northeast
following the vein for 260 feet. At the crosscut intersection the vein is
sparsely mineralized. Sixty feet northeast along the drift the vein widens
to 4 feet of quartz, 18 inches of which carries about 2 per cent of sulphide,
with a central 3-inch seam containing better than 50 per cent of sulphide.
An 18-inch channel sample taken across the mineralized part of the vein
assayed: gold, a trace; silver, 0:24 ounce a ton; lead, 0-05 per cent;
zine, a trace; antimony, a trace. Forty feet farther northeast, the vein
has narrowed to 5 inches of quartz carrying about 50 per cent of grey
sulphides, chiefly jamesonite. A 5-inch channel sample taken across the
vein at this place assayed: gold, 0:01 ounce a ton; silver, 18-33 ounces
a ton; lead, 4-44 per cent; zinc, 8-33 per cent; antimony, 2:13 per cent;
arsenic, nil. Another 40 feet northeast the vein has widened to 2 feet of
quartz and carries only a sparse mineralization, chiefly sphalerite. One
hundred and ninety feet northeast of the crosscut, there is an ore shoot
12 inches wide and 25 feet long containing about 50 per cent of jamesonite
and sphalerite. A 12-inch channel sample taken here across the vein
assayed: gold, 0-015 ounce a ton; silver, 14-67 ounces a ton; lead, 6:90
per cent; zinc, 9-75 per cent; antimony, 1-39 per cent; arsenic, 0-42 per
cent. Near the end of the drift, the vein splits into three parts, two of
which die away on entering a tongue of granodiorite, and the third, 6 inches
in width, continues northeast into the wall, along the faulted contact
between granodiorite and altered tuff.

No. 2 vein lies 100 feet east of the No. 1 vein, and is reached by a
crosscut from the north end of the drift on No. 1 vein. The vein is followed
by drifting for 138 fect southwest and 300 feet northeast from the 100-foot
erosscut. In the south drift, the vein maintains an average width of
1 foot, but is sparsely mineralized. Fifty feet south of the crosscut some
of the best-looking vein gangue carries about 5 per cent of jamesonite
and sphalerite. An 11-inch channel sample taken across the vein at this
point assayed: gold, a trace; silver, 2-14 ounces a ton; lead, 5-35 per cent;
