‡Ref.: Jones, E.L., Jr. & F.L. Ransome (1920), Deposits of manganese ore in Arizona, USGS Bull. 710-D: 134; MRDS file #10092679.
A group of 2 Mn claims about 2 miles east of the Road Tanks and about 32 miles SE of Salome. Located in May, 1918, and owned by T.G. Derby (circa 1920).
The deposit is a replacement deposit and lies in a detrital plain at an altitude of 1,300 feet.
The low hills north of the deposit are composed of lava flows, principally rhyolite, and these flows appear in patches scattered about the detrital plain where they have become exposed by erosion. The deposit occurs in one of these patches 100 feet in diameter. Dense, fine-grained,banded rhyolite about 2 feet thick is stained with manganese oxides, with here and there some softer material. The chief interest in connection with this deposit lies in the association of manganese oxides with a siliceous phase of rhyolite.
