Arizona Bureau of Mines file data.

A Pb-Ag-Zn-Au-Cu mine group located in the SE ¼ sec. 2, T.18S., R.10E. Owned at times, or in part, by the Francis Hagerman Mining Co.; and the Banner-Sierrita Mining Co.

Mineralization is oxidized, narrow, stranded, and lenticular quartz-calcite veins with disseminated argentiferous galena and spotty pyrite. Other sulfides and sulfosalts occur in sheared and metamorphosed Paleozoic limestone.

Workings include tunnel and shaft operations. 'Chloriders' produced high-grade silver ore in the late 1800's and early 1900's. Total sporadic production would be some 700 tons averaging about 60 oz. Ag/T, 40-50% Pb, 2% Cu, and minor Au.
