A former small surface and underground Zn-Pb-Cu-Ag-Au-Quartz mine located in the center of sec. 3, T24S, R16E (protracted), in the southwestern part of the camp, nearly ½ mile south of the Pride of the West Mine, adjacent on the SW to the Dudley Mine, and 2/3 mile west of Duquesne, on the south fork of Duquesne Gulch, 2.5 miles N of Mexico, 3/4 mile SW of Washington Camp, at an elevation of about 5,800 feet. Located in 1880 by Henry Holland, who shortly thereafter sold it to Dr. Luttrell & others, from California. Owned at times, or in part, by the Holland Smelting & Mining Co.; B. Coughlin (1891); F.L. Bartlett, of Denver (1896- ); the Duquesne Mining & Reduction Co. (1905- ); Callahan Zinc Lead Co. (1940-1944); Nash Mines (1951-1957); E.W. McFarland (1952-1957); and, Byrd (1945-1949); Carl Sandberg & Fred Williams (1964); Luttrell and Partners; and, A.B. Elder. Operated by the Simplot Mining Co. (1970). Owned by Rosario Exploration Co. (1973).
Mineralization is sulfides oxidized to iron oxides and carbonates with manganese oxide near the surface, in massive, irregular, lens-like orebodies with a gangue of silicated limestone, quartz, and calcium silicates, in pyrometasomatized Permian Naco Group limestone. Mineralization is along a garnetiferous zone close to Laramide granodiorite. The ore zones dip 45-65W between surface and 100 feet, then abruptly become nearly vertical between 100-200 feet, when the sulfide zone thins. Molybdenite appears to replace chalcopyrite & galena in isolated occurrences. Ore control was the contact of the Epitaph Dolomite with the Scherrer Quartzite; and bedding planes.
The mine is in the crystalline limestone near the contact of the quartz monzonite on the west and is probably on the southerly extension of the same general mineralized zone as the Pride of the West. The deposit occupies a zone about 50 feet in width, which dips about 60ºW., conformably with the limestone. It has a fairly regular footwall of crystalline limestone on the east, from which it is separated by about 2 feet of gougelike material containing a mineral that is mostly iron. The deposit and enclosing limestone are cut by a jointing or coarse sheeting that dips 25ºE. Sulphides are cut off by post-ore faulting.
The ore occurs chiefly in irregular, crudely tabular bodies, mostly dipping to the west. The lead ores, which contain most of the silver, occur mainly on the footwall side of the deposit; toward the hanging wall side the ores contain principally zinc with a little copper.
Mineral deposits of the Washington-Duquesne area occupy a limestone-sediment belt (2.5 miles long by 1.25 miles wide) surrounded by igneous rocks which also form detached masses and dikes within the belt.
Workings include a nearly 100 foot deep shaft (1881) and open cut operations. There are 4 inclined shafts, 100 by 40 foot open cut in 1915. Later it had 4 inclined shafts, opening it to a depth of 200 feet, which decend from the bottom of an open cut 100 feet long and 40 feet wide in the east side of the mineralized zone. Worked extensively prior to 1900 for high-grade, oxidized Pb-Ag ore. Total production would be some 80,000 tons of ore averaging about 18% Zn, 10% Pb, 2% Cu, 12 oz. Ag/T and minor Au.
