Other/historical names associated with this locality:
Silver Bill Mine; Costello claim


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 0.25 mile (ca. 402 m)
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 (ca. 61 m) deep existed in 1947. A relatively small, sporadic production occurred in the late 1800s and early 1900s, and a few hundred tons in the 1940s.
