Geologic setting

Geologic description

Gold is found in shallow bench and creek placers. Bedrock at the mouth of the creek is metabasalt; in the middle of the creek, the bedrock is chert and silicified dolomite; and serpentinite bedrock is near the head (Eberlein, 1977, p. 64) Concentrates contain gold, magnetite, ilmenite, picotite and zircon (Mertie, 1918, p. 256).

Production and reserves

Workings or exploration Shallow bench and creek placers were mined intermittently from 1915 to 1918 and from the 1930s to the 1960s (Eberlein, 1977, p. 64). Overbeck (1920) reported that the bench at the mouth was hydraulicked and 12,000 feet of bedrock cleaned.
Indication of production Yes; small
