A former small underground Pb-Zn-Ag-Cu-Au-Mo-Mn-Gemstone mine located in the North-central sec. 32, T.19S., R.25E. (Outlaw Mountain 7.5 minute topo map), on the west slope of Gleeson Ridge, immediately north of the Tom Scott Mine, approximately 100 yards (95 meters) SE of the Defiance Mine, ¾ mile (1.2 km) NE of Gleeson, and about 25 km East of Tombstone. Discovered 1890. Produced 1893-1978. Owned/Operated by the Gleeson Heights Minerals Co. (1978)

Mineralization is irregular, small stringers, pockets, and replacement bodies of oxidized base metal sulfides in Pennsylvanian-Permian Naco Group limestone adjacent to a quartz monzonite porphyry contact. Ore control was faults and fractures in the limestone; also along the dike perpendicular to bedding; and the contact of the limestone and intrusive bodies. Ore concentration was strong oxidation, resulting in the redeposition of malachite and azurite. Associated rock units are the Gleeson Quartz Monzonite and the Sugarloaf Quartz Latite Porphyry.

Workings are within a relatively elevated block bounded on the north and south by two subparallel faults which strike N.65º to 80ºS. This block ranges in width from approximately 50 feet at the surface to 80 feet on the 200 level.

Local structures include an eastward-dipping fault, possibly a segment of the Tom Scott fault zone, extends northward through the collar of the shaft. The limestone near the quartz monzonite contact strikes N30W, 40-50NE, N50-80E with a 40-80 dip. Faults cut by another fault system at right angles.

Workings are 160 meters long and 53.34 meters deep and include an inclined shaft 271 feet deep, together with several hundred feet of drifts, winzes and stopes. The bottom or 200 level connects with the Mystery adit. A large tonnage was mined during the late 1800's. 6,570 tons were produced during the periods 1922-1930 and 1938-1941.
