Comments
Comment (Deposit): Model Name = Placer gold deposit (Cox and Singer, 1986; model 39a), residual placer gold deposit, lode gold deposit?
Comment (Reference): Primary Reference = Singer and others, 1976
Comment (Workings): Workings / Exploration = Some surface exploration. Claim staking activity reported in 1977 by Eberlein and others (1977).
Comment (Geology): Geologic Description = The mine is both a placer and a lode deposit since it consists of eluvial and gold-bearing bench gravels about 20 feet thick which overlie decomposed Mesozoic granodiorite that contains gold-bearing quartz veins. The eluvial gold has delicate wire and crystal forms (Eberlein and others, 1977, p. 101). The regional geology surrounding the mine consists of undivided granitic rock; mostly hornblende granodiorite (Foster, 1970). Similar prospects exist on the Canadian side of the border. There are also many other placer claims along McArthur Creek (TC014) to the west.
