A former underground Au-Ag-Fe-Cu-Mn mine located in secs. 26 & 35, T7S, R21W, about ¼ mile North of the Traeger Mine, on the SE margin of the Laguna Mountains, on federal land. Owned by Messrs. C.D. Schoening, C.G. Norton, C.O. Baker, A. McIntyre, W.L. Kerr & J.C. Martin.
Mineralization is a sedimentary deposit with free, often ragged, gold grains to 1/20 inch diameter, 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 and considerably fractured and iron-stained. The vein is 0.46 meters thick, and strikes S.15ºW. Several lenticular quartz veins occupy divergent fault zones. The principal vein strikes Eastward and dips irregularly Southward and is from a few inches to 1½ feet thick. White to gray, brecciated quartz is somewhat intermingled with gouge, sericite and yellow iron oxide.
Workings are relatively shallow shafts (22 feet deep - circa 1931; 80 feet deep 50 feet North of the vein (1932)) with a few shallow old stopes, tunnels and open cut operations. The mine group was worked intermittently from the 1860's to about 1940. During 1931 a small quantity of rich ore was mined combined production of the Las Flores group. 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.
