A former small surface and underground Ag-Mn-Pb-Cu-Zn-Au-Sb occurrence/mine located on one patented claim in the center of sec. 4, and the NE¼ of sec. 9, T23S, R16E (protracted), ¼ mile S of the Hardshell Mine; ¼ mile NE of the Black Eagle Mine, 1½ miles SW of Harshaw, adjoining the Hermosa property on the west and situated in the east slope of the same ridge, on private (patented) land. Produced 1900-1944. Owned at times, or in part, by the Hermosa Mining Co., New York; Miller; Mr. L. Rochine; Mr. T. Farrell; and Mr. A.R. Byrd. Owned by Mr. Grover Marstellar and Otto Herald and Associates (1938). Operated by Mr. L.R. Brown (1944).

Mineralization is shear veins and replacement bodies of manganiferous silver ore in faulted, brecciated, silicified, and kaolinized limestone conglomerate and rhyolite in Jurassic-Triassic volcanics. Minor, mostly oxidized base metal sulfides and gold. The manganese replacement bodies occur in fracture zones. The other ores occur in subparallel shear vains cutting limestone blocks or along bedding planes of the limestone. Ore concentration was secondary enrichment along fracture zones. The ore bodies are separated by various sized bodies of lower grade material or by barren siliceous limestone. Associated rock units include the Chief Conglomerate, Breccia Member. Silver ore was mined from a vein located several 100 feet east of the Salvador manganese deposit. Limestone bedding planes containing ore bodies strike W and dip about 35N. Ore bodies range from small high grade bunches to average grade masses a few tens of feet in length and several feet in width. The Salvador vein is located almost on the projected course of the Hermosa vein, but is separated from it by a zone of upfaulted quartzite. Other local structures include the NW-trending American Fault. Limestone block covers a surface area 900 feet long and 200-300 feet wide, and is completely surrounded by volcanic rocks. Small amounts of manganese minerals are found in limetsone but the principal deposits crop out along the SW end of the limestone blcok. Cryptomelane and braunite are the chief hypogene minerals.

Tectonic features include the Corral Canyon Fault Block with downthrow to the SW.

Workings include a 200 foot tunnel; a 50 foot shaft; various drifts, crosscuts, and stopes; plus 2 50 foot adits; several shallow open cuts. Openings aggregate some 1,000 feet of work, including a 200 foot long tunnel, a 50 foot deep shaft, drifts, crosscuts and stopes. Some 1,000 tons of 30 oz. Ag/T ore was mined in the 1880's and 2,800 tons of 20 oz. Ag/T, with minor Pb, Cu, Zn and Au, and a high Mn content were shipped in 1936-1944. Manganese ore production is not known from this deposit; a few shipments of hand-sorted manganese ore may have been made during WW I. Early 1900's assay values averaged 30 oz/ton Ag; 19% Mn. 1941 values averaged 13.5% Mn, 0.12% Cu, 1.1% Pb, 1.3% Zn, 1.9% Fe, 67.4% Si, 10.7 oz/ton Ag.
