Production Produced and estimated $2 million in Ag, Pb, Zn, and Au from 1899-1960s.
Status Past mining.
Estimated resources Unknown.
Geologic maps Browne (2012), scale 1:24,000; Kun (1974), scale 1:24,063.
Geophysical data Inadequate aeromagnetic and aeroradiometric coverage.
Favorable rocks and structures Fracture-hosted vein systems on the Middle and Lower Members of the Wallace Formation.
