A former small surface and underground Ag-Pb-Au mine located on 1 claim, in the center of sec. 11, T.20S., R.22E, approximately 1/4 mile
S of Tombstone, on private land. Discovered, and claim patented, in 1880. Owned at times, or in part, by Costello and Giacoma Brothers (sic).

Mineralization is a replacement deposit of irregular, oxidized orebodies of argentiferous galena along a 'northeast' fissure zone cutting Cretaceous Bisbee Group limestone and shales.

Local structures include the Tombstone Basin. Faulting occurred on WNW and NNW trends, post-mineralization.

Workings are both on surface and underground. A shaft at 200 feet deep existed in 1947. A relatively small, sporadic production occurred in the late 1800's and early 1900's, and a few hundred tons in the 1940's.
