A former small underground Pb-Ag-Zn-Cu-Au-V-(Cd) mine located in the center of sec. 11 and 14, T.20S., R.22E, ¼ mile south of Tombstone, on private land. Discovered by A.E. Sheiffelin, February, 1878. One of Tombstone's first mines, included in the Tombstone group, adjoins the Empire shaft. Owned at times, or in part, by the Tombstone Mill & Mining Co., Tombstone Consolidated Mines Co., Bunker Hill mines Co., and the Tombstone Development Co.
Mineralization is a replacement deposit oxidized base metal sulfides in replacement orebodies in the lower section of the Cretaceous Bisbee Group beds along anticlinal rolls and in pipes where rolls are cut by 'northeast' fissures.
Local structures include the Tombstone Basin; N-trending dikes and NE fissures.
Workings include shafts, drifts, winzes and open cuts. Workings length is 1,219.2 meters in overall area 304.8 meters long, 228.6 meters wide and 152.4 meters deep, including the Empire and adjoining shaft. Several thousand tons of ore were produced in the late 1800's and early 1900's. After 1883 production was included under the Goodenough and the Tombstone group in ABGMT-USBM file data.
