A former Ag-Au occurrence/mine located in the N½SW¼ sec. 2, T21N, R21W, G&SRM, 6 miles W of Union Pass and 3 miles East of the Katherine Mine, on Bureau of Land Management administered land. Owned by G. J. Alton, H. Williams and Anita G. Williams (1977). The USGS MRDS database stated accuracy for this locality is 500 meters.
Mineralization is a deposit hosted in granite. The ore body is comprised of stringers that strike NW and dip 30SW at a width of 45.72 meters and a length of 914.4 meters. Free gold occurs in clean, oxidized quartz and calcite. A large vein comprised principally of calcite, cut by a great number of small stringers of quartz. The vein takes a curved course trending NW and a length of ½ mile (about 1 km). About midway between the ends it is 150 (46 meters) feet wide. It appears to occur in a shattered rhyolite which may have been replaced to a certain extent by both the calcite and quartz. Associated rocks include Pliocene-Neoproterozoic rhyolite. Local rocks include Middle Miocene to Oligocene volcanic rocks.
Regionally Tertiary flows strike NW and dip 30 to 40NE, and overlie Precambrian granite and gneiss with NW to NNW-trending normal faulting.
Workings include underground openings comprised of a small inclined shaft plus a number of small tunnels beneath the outcrop.
Gold values are about $2.40/ton (period values).
