A former surface Au-Fe-Mn mine located in sec. 13 and in West-central sec. 12, T1N, R16W, in Cemitosa Wash, a short distance West of Cemitosa Tanks, about 7 air miles E of Ocotillo, northern Kofa Mountains (Alamo region), on federal land.
Mineralization is spotty, finely divided, free gold in fractures and breccia with gouge, calcite, and iron and manganese oxides, in a 10 foot (3.05 meters) wide brecciated zone in andesitic volcanics (andesite porphyry). This zone trends N.50ºW., has a vertical dip, and can be traced for 1,500 feet (457 meters) along the westerly slope of a basalt-capped mesa north of the Cemitosa tanks. The country rock is a reddish to brown andesite porphyry which apparently grades into the basalt capping the mesa. The brecciated zone is iron-stained and contains numerous stringers oc calcite, some of which are 1 foot wide. Part of tjhis calcite is dark-colored and probably contains manganese. Gold can be obtained by panning.
Workings include small discovery holes. $3 a ton in Au. No production record.
