A former small underground Ag-Pb mine located in East-central sec. 16, T.20S., R22E, 2 miles SW of Tombstone, on private land. Operated at times, or in part, by the Mellgren Group and the Tombstone Silver Fields Co.
Mineralization is silver values in an oxidized fissure vein cutting Cretaceous Bisbee Group beds. The host rock units are the Bisbee Group beds and the Ajax Quartzite.
Workings include a shaft(s). Several huindred tons of ore were produced intermittently in the late 1800's and during the 1920's and 1930's.
Pre-1932 production figures were included under the Mellgren group, mixed with Bunker Hill and Bonanza figures.
