Mineralization is a Cu vein deposit hosted in greenstone. The ore body strikes NW and dips NE. The vein is pyritized and kaolinized greenstone with chalcopyrite. Local rocks include Mesozoic volcanic rocks, unit 2 (Western Sierra Foothills and Western Klamath Mountains).
Workings include underground openings comprised of a shallow shaft that was dewatered in 1943.
Produced $8,000 (period values) during WWI.
