‡Ref.: Jones, E.L., Jr. & F.L. Ransome (1920), Deposits of manganese ore in Arizona, USGS Bull. 710-D: 134; MRDS file #10048186.
A group of manganese claims located about 2 miles west of the Derby claims. Owned by W.W. Howard & Associates.
The deposit occurs in a small area of vesicular lava, which is surrounded and partly overlain by detrital material. It is exposed for 75 feet in an open cut, is about 6 inches (15 cm) thick, and dips about 10ºN. The manganese oxides are small crystals of manganite in minute seams or crevices in black siliceous material, which is partly replaced by fine-grained, amorphous manganese oxides. The siliceous material looks like chert, but it is probably a phase of the lava flow, and apparently the manganese oxides are closely associated with it.
Workings include an open cut.
