Geologic setting

Geologic description

Placer gold occurs in alluvial deposits overlying kyanite schist on Gold Run Creek. A few ounces of placer gold were recovered during assessment work in 1931 or earlier. Scheelite is a common mineral in the placer concentrates, and kyanite, scheelite and wolframite make up a considerable portion of a sample obtained about 11 miles upstream from the mouth. Kyanite in the schist bedrock occurs in bands of coarse, bladed crystals, some as much as 10 inches in length. The width of the zone of kyanite in one prospect cut is 2 feet. It is exposed for a distance of 18 feet. Other narrower bands have been encountered in the same area (Anderson, 1947).
