A manganese-iron mine located in the East-central sec. 24, T7N, R18W. Owned at times, or in part, by Townsend; and, the Manganese Co. of America.

Mineralization is irregular, lenticular masses and strands of manganese oxides mixed with iron oxides and calcite in breccia, along a fracture vein in metamorphosed Mesozoic sedimentary rocks.

Workings included an adit and tunnel operations. The mine produced a small amount of high-grade, picked manganese ore during WWII, and some 2,000 long tons mined and milled in 1953.
