Grey Copper Group (Locality 29)
Reference: Annual Report of the Minister of Mines, British Columbia, 1917,

The Grey Copper group of claims is on the south side of upper Bear
river about 5 miles above its junction with American creek. A brecciated
zone, 6 feet wide, in argillite, is cemented with calcite and contains a 6-inch
streak of tetrahedrite. Several tons of ore extracted from this paystreak
assayed 375 ounces of silver a ton.

Hallie Claim (Locality 88)
Reference: Annual Report of the Minister of Mines, British Columbia, 1909.

The Hallie mineral claim is on the south fork of Glacier creek near
the forks. A brecciated zone up to 8 feet wide in argillite is mineralized
with quartz and pyrite.

Harner Group (Locality 111)

References: Annual Report of the Minister of Mines, British Columbia, 1926 and 1928 ;
Geol. Surv., Canada, Memoir 159.

The Harner group is at an elevation of 4,500 to 5,000 feet in Magee
pass, Marmot river, 1 mile east of the Washington group. The country
rock is argillite and overlying volcanic rocks of the Hazelton group
intruded by a stock of augite porphyrite. Coast Range intrusives out-
crop half a mile west of the property.

Two veins are exposed by open-cuts for lengths of 500 feet each. The
difference of elevation between the lowest and highest outcrops of each vein
is 150 feet. The upper vein strikes north-northwest and dips 40 to 70
degrees east, and the lower vein strikes west-northwest and dips 40 to 70
degrees north. The upper vein is 2 to 9 feet wide. As the exposures are
oxidized, some rust may have spread laterally beyond the vein boundaries,
making the vein appear wider than it actually is. The lower vein is 1,000
feet south of the upper vein and is similar in size and appearance. A short
adit driven to the upper vein exposes only a few, rusty, quartz stringers
instead of a good-sized vein as was to be expected from surface exposures.
The veins consist of quartz mineralized with pyrite, galena, and sphalerite.
Good values in silver and gold have been obtained from the outcrops.

Heywood Mining and Development Company
References: Annual Report of the Minister of Mines, British Columbia, 1928 and 1929,
The Heywood Mining and Development Company was organized in
1928 to develop fourteen claims on the east side of American creek north
of Basin creek. It is stated that silver-lead float was found on the north
side of Basin creek.

High Grade Group (Locality 111)
Reference: Annual Report of the Minister of Mines, British Columbia, 1927.

The High Grade group of mineral claims adjoins the Harner group
in Magee pass, Marmot river, and is held by the Marmot River Gold
Mines, Limited. There are three veins on the group, two of which are
continuations of veins on the Harner group.
