And sphalerite appear to have preserved original bedding structure. Another Moyer orebody was composed of mixed sulfides thoroughly shot through with secondary cerussite and limonite (Emmons et al., 1927).The Moyer has produced lustrous, black, 2.5-cm sphalerite crystals on pyrite matrix (Henderson, 1926; Kosnar, 1976); hemimorphite; some very nice, although small (1.2-cm) modified crystals of galena; and some beautiful pyrite specimens showing combinations of the octahedron and pyritohedron (ER collection).CARBONATE HILLCarbonate Hill lies between the Pendery fault on the west and the Iron fault on the east. The Tucson-Maid reverse fault passes through the hill and appears to have been a factor in the development of sulfide replacement orebodies at the Wolftone mine.The mines on Carbonate Hill were the second major group developed on secondary lead-silver bonanza deposits in the early days. As in the California Gulch area, the orebodies occur mainly in the upper Leadville limestone. Just below and sometimes adjacent to these orebodies lay the oxidized zinc ores for which the area is best known; these were not considered economical in the early days of mining and were temporarily bypassed.Common botryoidal smithsonite was reported from the Maid of Erin mine (Loughlin, 1918), and other mines in the area reported fine smithsonite druses and mixtures with iron and manganese oxides. When the district finally did begin to produce zinc, the result was significant: $43,000,000 worth from 1910 to 1916, most of it from Carbonate Hill.Wolftone Mine/A. M. W. PropertiesThe Wolftone mine, named for Theobald Wolfe Tone, the spiritual father of modern Irish nationalism, was located in 1876 by Samuel Morgan and Aden Alexander. Situated on Carbonate Hill, California district, 1.6 km (1 mile) from Leadville, five shafts were sunk ranging from 9 to 25 meters in depth and the ore was said to have a value of $250 per ton (Corbett, 1879).Dumps of the Maid of Erin mine, ca. 1892 (from Engineering Magazine).Malta Smelting and Mining Company was the claimant requesting a survey in 1880; patent was granted later that year (Bureau of Land Management files).“At a depth of 633 feet ore was first struck, and a body of iron
