A former small surface and underground Mn-Ag mine located in West-central sec. 14, T.20S., R.22E, approximately 1½ miles S of Tombstone, on private land.
Mineralization is small, irregular pipe-like bodies of argentiferous manganese in fault breccia in Pennsylvanian-Permian Naco Group limestone on the Anchor Fault, which srikes N-S and dips 45E. Breccia and orebodies are 1.5 to 3 feet thick. The Mn mineralization phase occurred after the main Fe-Pb-Zn phase in the district.
Local structures include the E-W-trending Prompter Fault, south edge of the Tombstone Basin.
Workings include tunnels and surface openings. The tunnel is 300 feet long and follows the fault. A relatively small production occurred around 1916-1917.
