where the vein widens to 2 feet. A 20-inch channel sample taken across
the vein 6 feet south of this raise assayed: gold, 0:02 ounce a ton; silver,
19-64 ounces a ton; lead, 18:41 per cent; zinc, 1-63 per cent. There is
another raise 145 feet north of the shaft and there a stope about 30 feet
wide extends through almost to the 100-foot level. Forty feet north of
this raise the vein narrows to 12 inches and splits into two parts. The
east branch pinches to 3 inches, and in a few feet passes into the east wall
of the drift. The main branch ranges from 4 to 6 inches in width for 45
feet to the face of the drift and contains from 1 to 2 per cent of sulphides.
A 6-inch channel sample taken across the vein at the face of the drift
assayed: gold, 0-06 ounce a ton; silver, 0:21 ounce a ton. A 12-inch channel
sample taken across the vein 8 feet south of the junction of the two arms
of the vein assayed: gold, 0-04 ounce a ton; silver, 0-085 ounce a ton; lead,
nil; zine, nil; arsenic, 2-86 per cent.

The No. 5 or “Mullan” vein is developed by a vertical shaft 25 feet
deep and a rock cut and adit 65 feet in length, which connect with the shaft.
The vein has an average width of 14 inches and contains irregular ore
shoots. In the shaft the vein quartz appears relatively barren. A 14-inch
channel sample taken across the vein at the bottom of the shaft assayed:
gold, 0-01 ounce a ton; silver, 5:38 ounces a ton. Samples of ore piled
near the portal of the adit carry from 5 to 10 per cent of sulphide. The
quartz gangue is cut by rusty carbonate stringers and carries galena,
sphalerite, tetrahedrite, and a little chalcopyrite. A representative sample
of the ore dump assayed: gold, 0:01 ounce a ton; silver, 27-89 ounces a
ton; lead, 2-91 per cent; zinc, 5-64 per cent; copper, 0:62 per cent.

Attention is drawn to the high gold content of the arsenopyrite ore
of the No. 8 vein. Ore of similar appearance occurs on the surface in No.
4 vein, 150 feet north of the main shaft. Should surface trenching prove
Nos. 3 and 4 veins to be one vein, the ore could be efficiently handled by
an adit run as a drift.

The Surprise claims are immediately north of and adjoin the Silver
Standard property. In 1912 and 1913 a crosscut adit was driven and one
vein was explored by a drift and raise. There is no record of work done
since 1917 when the original owner, W. Thompson, sold the claims to B. R.
Jones.

The Surprise adit is at elevation 1,485 feet, the portal being 1,250
feet northeast of the portal of the main crosscut adit on the Silver Standard
property. The adit is driven south 37 degrees east for 740 feet, and 200
feet from the portal a drift runs northeast for 96 feet and southwest for 20
feet from the crosscut. From the northeast drift two raises were driven
through to the surface. The drift follows along a 6-inch vein of quartz and
calcite, which is sparsely mineralized with pyrite. At the face of the north-
east drift the vein has decreased to a 1-inch stringer, and 6 feet from the
face of the southwest drift the vein ends against a cross fracture.
