A former surface and underground Ba-Cu-Pb-Ag mine located in sec. 26, T9S, R12E, about 3 miles ENE of Owl Head Buttes, on private land.
Mineralization is a vein deposit hosted in the Pinal Schist. Veins are 1 to 2 cm distributed sparsely over a 500 foot width. The ore zone strikes N30-60W, dips 45-80W, at 152.4 meters wide and 2133.6 meters long. Gossan is seen on the outcrop. One prospect pit is salted with Laramide porphyry. Mineralization is largely baryte along a fault with some copper oxide and occasional galena. Veins are crosscut by faults. Alteration is propylitic, sericitic with oxidized veins, illite. Related structure is a fault trending N35W, dipping 65S.
Workings include a major shaft deeper than 675 feet; a minor shaft approximately 610 feet; an adit with raises to the surface; and 10-15 prospect pits. No production data is available. A likely producer.
