A U-Cu-Pb-Zn claim with surface and underground workings located in secs. 5 & 8, T.18S., R.11E., on the western flank of the Sierrita Mountains, 11 miles W of Twin Buttes and about 25 air miles SW of Tucson. Owned by Manuel Obregon of Tucson.
Mineralization is a radioactive fissure vein in a light-colored, slightly foliated granite. In some places the granite contains irregular xenoliths of impure quartzite and consists of of steeply-dipping layers, of NW-trend. The ore body is lenticular at6 1.22 meters wide, striking N25W and dipping 75SW. Alteration is argillitic and partly silicified.
Local structures include fractures, dikes, and foliation of granite, all of which trend NW.
Workings include a 16 foot (4.88 meters) deep shaft.
