A former surface and underground Silica flux-feldspar-scrap mica-U mining operation located in the North-central sec. 2 & East-central sec. 11, T.13S., R.7W. (protracted)., 11 road miles SW of Ajo on the Cabeza Prieta Game Range.
Worked since about 1946 from a small open pit. Owned at times, or in part, by the Pumice Corp. of Arizona; Ballestreras; and the San Antonio Mine Co.
Mineralization is irregular pegmatite dikes and masses in Mesozoic granitic intrusive. Uranium minerals are coatings on fractures in pegmatite and granite.
Workings are open pits with overall workings at 15.24 meters long and 4.57 meters wide. Small lots of scrap mica and feldspar were recovered. Several tens of thousand tons of silica flux were shipped to smelter. Flake and ground mica used for mud and roofing material.
