A former underground Au-Ag-Fe-Cu-Mn mine located in secs. 26 & 35, T7S, R21W, on the SE margin of the Laguna Mountains, about 1½ miles N of the Gila River, on a military reservation.
Mineralization is free, often ragged, gold with silver and minor copper, in lenticular and brecciated quartz veins, usually containing abundant iron oxides and some manganese oxides, siderite, gypsum and gouge, along a fault or fracture zones in Mesozoic schist cut by dikes and irregular masses of granite and pegmatite. The gold is related to Early Tertiary muscovite pegmatites. A quartz vein outcrops a feet feet west of a parallel dike of aplitic granite. The vein is 2 feet or more wide, dips westward and extends S.15ºW. for about 300 feet, then changes strike and narrows.
Workings are relatively shallow shafts, tunnels and open cut operations. Workings consist of a stope from the surface to a depth of 25 feet and for a length of 75 feet, and an inclined shaft. The mine group was worked intermittently from the 1860's to about 1940. They produced some estimated and recorded 500 tons of ore averaging about 0.4 oz. Au/T, 0.1 oz. Ag/T and 198 pounds of copper.
