A former small surface and underground Pb-Cu-Ag-Au-Zn-Baryte mine located in the SE¼ sec. 12, T18s, R10E. Produced 1880-1959. Operators included Arizona Lead Mines Co., Dry Concentrates, Ramsdell Mines Co., and the Shafer Mining and Milling Co.
Mineralization is a tabular ore body in a permeable shear zone with fractured limestone that facilitated or controlled replacement. Ore occurs on both walls of the fault where limestone is highly fractured. Limestone is veined with quartz-pyrite-galena-sphalerite, a little Cu staining, and a yellow Pb mineral. The ore body is 15.24 meters thick, strikes N20W and dips 24W. An associated rock unit is a granite. Alteration included quartz-sericite-pyrite; pyrite-gossan.
Workings included the main shaft with short drifts & crosscuts; open cut with a stope. Workings are 42.67 meters deep.
