Location and accuracy The B.C. mine is located in sec. 22, T. 15 N., R. 23 E., of the Copper River Meridian, about one mile from the Canadian border, along a tributary of McArthur Creek. It is location 14 of Singer and others (1976), and locality 2 of Eberlein and others (1977). The location is accurate to within a mile.

Geologic setting

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.
