A Pb-Ag-Zn-Cu-Au mine located in sec. 11, T.17S., R.12E. Owned at times, or in part, by the Prosperity Smelting & Mining Co.; Helmet Peak Mining & Milling Co.; and the Great Northern Exploration Co., Inc.

Mineralization is complex, partly oxidized silver-lead-zinc-copper minerals in irregular pockets, lenses and pods along fracture zones in brecciated, altered, Late Cretaceous andesite volcanics and clastic sediments within the San Xavier thrust fault block.

Workings include shaft operations. Worked sporadically from the late 1880's to 1955. The group produced an estimated and reported total of some 1,000 tons of ore averaging about 7% Pb, 7 oz. Ag/T, 1% Zn, 0.5% Cu and minor Au. Most high-grade ore was mined prior to 1900.
