A former small surface and underground Cu-Ag-Au-Mo-U mine located in the NW¼SW¼NW¼ sec. 20, T. 11 S., R.16E., near Mount Bigelow, NE of Stratton Camp Spring and S of Marble Peak. Owned at times, or in part, by the Stratton Copper Co.; and the Stratton Consolidated Copper Co.
Mineralization is a skarn deposit with thin fracture fillings and disseminations of chalcopyrite and pyrite in garnet-epidote skarn in pyrometamorphosed Paleozoic limestone along a bedding plane fault. Bornite and molybdenite are associated with quartz in depth. The ore zone is 106.68 meters long and 0.76 meters wide strikes NW and dips 27NE. The host rock units are the Abrigo Formation, the Martin Formation, and the Escabrosa Limestone. An associated rock unit is the Leatherhead Quartz Diorite. The mineralization is restricted to the bottom 5 feet of tactite and forms a zone 2.5 feet thick.
Local structures include a N45-55E fault shifts the tactite zone 500 feet NE. Bedding plane faults strike NW and dip NE & SW.
Workings include an 80 foot long inclined shaft and prospect adits. The lower 30 feet of the shaft is flooded. 2 adits about 50 feet long are located about 800 feet N of Stratton Spring. A few hand-sorted tons of high-grade ore were shipped in the past.
Reserves in the south mineralized zone are estimated at 2,000 tons indicated ore and 8,000 tons inferred ore at 2-3% Cu. The north mineralized zone is estimated to contain 15,000 tons of tactite, probably too low in grade.
