Goldpan vein is about 18 inches wide. Specimens from both veins have
assayed 0-3 ounce of gold and 15 ounces of silver a ton. The McGee vein is
1 to 4 feet wide, and contains sphalerite, pyrite, galena, .nd chalcopyrite.
An assay shows 11 ounces of silver a ton but less than 0-1 ounce in gold.
The Stimulator vein is about 18 inches wide, but where sampled is of very
low grade.

Black Bear Claim (Locality 87)
Reference: Annual Report of the Minister of Mines, British Columbia, 1924.

The Black Bear claim adjoins the Gypsy claim of the Portland Canal
Mining Company’s holding on Glacier creek. At an elevation of 1,500
feet in argillite there is a quartz vein 10 feet wide containing pyrite,
galena, sphalerite, and fragments of argillite.

Black Bear Group (Locality 83)

Reference: Geol. Surv., Canada, Memoir 32.

The Black Bear group is on the west side of Bromley glacier 24 miles
from its lower end. The claims are at the contact between argillites and
a belt of dykes. Several crushed zones up to 20 feet wide in the argillite
are silicified and mineralized with pyrite.

Black Hill Mining Company (Locality 91)
References: Annual Report of the Minister of Mines, British Columbia, 1928 and 1929.

The holdings of the Black Hill Mining Company are on the east side of
the south fork of Glacier creek and consist of the Black Hill group and other
claims that are a relocation of the older Excelsior group.

The country rock is a body of augite porphyrite holding inclusions of
argillite and of volcanic rocks. The edges of the porphyrite body show
concordant relations in many places with the bedding of the intruded
argillite.

The mineral deposits consist of two series of veins. The veins of one
series strike north, are about a foot wide, consist of quartz, calcite, and
barite, are well mineralized with sphalerite, galena, tetrahedrite, and
jamesonite, and carry good silver values. The veins of the other series
strike east, are about 8 inches wide, and consist of quartz sparsely mineral-
ized with sphalerite, galena, tetrahedrite, and chalcopyrite.

Twenty tons of ore shipped in 1929 yielded 2,920 ounces of silver and
6,460 pounds of lead. One ton shipped in 1930 yielded 112 ounces of silver
and 168 pounds of lead.

Bornite Group (Locality 24)
Reference: Annual Report of the Minister of Mines, British Columbia, 1930.

The Bornite group is north of upper Bear river and adjoins the Red Top
and Barite groups. Chalcopyrite and galena mineralization is reported.
