A Cu-Ag-W-F-U, silica mining area located in the Whetstone Mountains.

Mineralization is of several types: (1) Copper oxides, carbonates, and sulfides with pyrite as veinlets and disseminations in fractured porphyry dikes and Laramide granodiorite, and in pyrometasomatic lenses in folded and faulted Pennsylvanian and Permian limestone; (2) Tungsten mineralization with sparse sulfides in quartz veins cutting Precambrian granitic rocks, pegmatite dikes, or Pinal Schist; (3) Fluorspar along a quartz vein in Precambrian Pinal Schist; (4) Relatively weak oxidized uranium mineralization along an andesite dike cutting Precambrian granitic rock; and, (5) A large Precambrian quartz body, (6) Spotty copper minerals, mostly oxidized, in Cretaceous sediments intruded by Laramide rhyodacite intrusives, strong faulting.

Operations include shaft and open pit mining. Worked in 1955-1956 and 1962-1963.

Workings include several, scattered, relatively small mines and prospects. About 2,100 tons of copper ore, a few tons of tungsten concentrates, some 20,000 tons of fluorspar, minor shipments of uranium ore, and 50,000 or more tons of silica flux were produced in this district.
