A former Ag-Zn-Sb-Cu-Pb mine on the Comstock lode.
Structure: North-Trending Anticline; Regional Dip To West Or Northwest Faults
Alteration: Propylitization, Oxidation,Pyritization
Deposit: This deposit is found on the comstock vein proper, and consists fo silver sulfide ore with a substantial gold content. The deposit is part of the comstock lode, epithermal precious-metal veins generally found in the alta andesite. The mine is 2500 feet deep and explores the comstock vein, outliers of the consolidated virginia bonanza, and the hardy vein. Sporadic production from 1859 to 1873, but wellover 40,000 tons ore at from $8 per ton to $2500. Per ton production from 1874 to 1925 was 439,137 tons ore averaging $41.16 per ton in mostly silver values. ; info.src : 1 pub lit vein, comstock fault
Deposit type: Epithermal vein, Comstock
