A former small underground Ag-Mn-Au mine group located in the southern border area of secs. 14 & SE¼ sec. 15, T20S, R22E, G&SRM, 1½ miles S of Tombstone, on private land. The Prompter shaft is in the NW¼SW¼ sec. 14 & about 1250 feet E of the Oregon Mine. Owned by the Boston & Arizona Smelting & Reduction Co. and the Tombstone Development Co.

Mineralization is irregular, pipe-like to tabular replacement ore bodies, mainly oxidized manganiferous-silver ores, along the footwall of the Prompter fault zone in Pennsylvanian-Permian Naco Group limestone and controlled by bedding plane slips and 'northeast' fractures.

Local structures include the Prompter Fault, a reverse fault with E-W trend and a steep south dip.

Workings include shaft openings and total 1371.6 meters in length and 167.64 meters deep. There are 2 shafts, 5 levels. The length of the workings is estimated from mine map. A few tens of thousands of tons of ore were produced in the group at irregular intervals from 1883 to 1950. The 1883 to 1891 production figures were reported under the Vizina Mine in ABGMT-USBM files. Other Oregon-Prompter data are included under the Tombstone group.
