The Red Cliff group of claims is on the west side of American creek
near its mouth. Early development work disclosed moderate-sized bodies
of copper ore, but as the deposits were on a very steep hillside subject to
snowslides a long adit was necessary to provide safe working conditions.
In 1910, 14 tons of ore were shipped that returned 8-20 per cent copper,
and 2-24 ounces of silver, and $5 in gold a ton. In 1912, 1,249 tons of ore
were shipped, but as the grade of ore was rather low work was supended.
Four levels 100 feet apart have been driven and several thousand feet of
underground work has been done.

The ore-bodies occur in irregular masses in volcanic rocks of the Hazel-
ton group. The largest body is 75 feet long and 5 to 17 feet wide. Another
is 100 feet long and 4 to 6 feet wide. The metallic minerals are pyrite,
pyrrhotite, chaleopyrite, and sphalerite. The gangue is mostly country
rock, silicified to some extent and seamed locally with quartz and calcite.
Deposits of similar appearance have been discovered but have not been
developed.

Red Reef Group (Locality 97)

Rees. Annual Report of the Minister of Mines, British Columbia, 1912, 1913,
and 1928.

The Red Reef group of claims is on the east side of Bear river near
its mouth. Considerable development work was done on the property in
1910 and 1912. The mineral deposit is locally 100 feet wide and has been
traced for 2,000 feet or more. The deposit is mineralized with quartz,
pyrrhotite, and chalcopyrite. Locally the deposit is a quartz vein 25 feet
wide.

Red Top Group (Locality 24)

The Red Top group is on the north side of upper Bear river opposite
the George Copper group. The mineral showings were discovered many
years ago and have been developed in a small way from year to year. The
development work, consisting of two adits 200 and 300 feet long, respec-
tively, and several open-cuts, has been done on a chalcopyrite-bearing
replacement deposit and a vein of the silver-lead type.

The rocks traversed by the vein are tuffs and lava flows of the Haze!-
ton group. They strike northeast, and dip gently northwestward, and are
cut by dykes, some of which can be followed for distances of over a mile
and vary little in width. The vein is 4,100 feet above sea-level, strikes
north 80 degrees east, and dips 50 to 60 degrees southward. It has been
traced by open-cuts for a distance of 800 feet. A crosscut adit 200 feet
long has been driven northward from a point 300 feet below the outcrop of
the vein but has not been driven far enough to encounter the vein. The
vein varies from 1 to 8 feet in width and contains galena, sphalerite, pyrite,
and a little chalcopyrite in a gangue of quartz, calcite, barite, and Jasper.
