Geologic setting

Geologic description

The Great Bear prospect is in black phyllite and felsic phyllite that have been intruded by Cretaceous metagabbro (Redman and others, 1989). The deposit was discovered in 1900 and diamond drilled that fall, but there are no other workings. The deposit was reported to contain gold and nickel, but U.S. Bureau of Mines samples failed to detect any elevated metal values (Redman and others, 1989). The rocks in the general area are Lower Permian through Upper Triassic volcanic rocks, with subordinate clastic and carbonate strata, and their metamorphosed equivalents (Gehrels and Berg, 1994).
