A former small surface and underground Au-Ag-Mn mine located in the SE ¼ sec. 22, T.14S., R.27E, approximately 3 miles NE of Dos Cabezas, N end of Bean Canyon, on private land. Owned and operated by Mr. Hyde Bean (1973- ).

Mineralization consists of spotty gold and minor silver values associated with irregular quartz veins along fault fissures cutting Cretaceous schistose rocks and with minor manganese oxide in limy beds. The host rock unit is the Bisbee Group, including limestone and schistose rocks.

Local structures include an E-W fault south of the mine juxtaposes Precambrian quartz monzonite to the south with the Cretaceous Bisbee Group.

Workings include a shaft and surface workings. A few hundred tons of ore were produced from 1884 to 1933.
