A former surface and underground Mn mine located in sec. 13, T8S, R5E, about 1¾ miles S of Chuichu, and about 12 miles W of Eloy, on Indian Reservation land. Discovered in 1955 and produced 1955-1956 by Bethel I. Richardson, Ernest Wilkinson, and Leonard J. Hamelitz, of Casa Grande.
Mineralization is a replacement deposit in fracture zones in coarse-grained granite. Ore bodies are pods and irregular and are 9.14 meters long, striking N25E, and dipping 55NW. Related structure is block faulting trending NNW. Some mineralization occurs around fault breccia.
Workings include a 55 foot inclined shaft, and a 30 foot drift with shallow open cuts on either side of the shaft. All equipment except the headframe was removed and the property was idled in 1956.
Assay data: Sorted ore contained 29% Mn.
