A former surface and underground Au-Ag-Fe-Cu-Mn mine located in sec. 26 & 35, T7S, R21W, 400 feet NW of the Traeger Mine on the SE margin of the Laguna Mountains. Owned by C. Baker & A. McIntyre (1931).
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.
Workings are shallow cuts and an old shaft, probably about 190 feet deep that inclines 30ºW. near surface, plus tunnels. 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.
