A former surface Mn mine located in West-central sec. 36, T10N, R14W, GSRM, 9.6 km (6.0 miles) SW of the Alamo Lake Dam, on state land (located claim/state lease). Discovered 1953. Owned by the State Of Arizona(1973). Operated by Mr. D.C. Roberts, Sub-Lessee (1973). MRDS database accuracy for this location is not stated.
Mineralization is mainly pyrolusite, mixed with sandstone and calcite, in relatively short, lensing, overlapping bands, separated by barren sandstone of Tertiary age. Local rocks include Middle Miocene to Oligocene sedimentary rocks.
Workings include surface and underground openings comprised of tunnels, cuts and an open pit. A small tonnage of ore at about 10% Mn was produced in the 1950's.
