A former underground Pb-Ag-Cu-Zn-Au mine located in the SW¼SE¼ sec. 3, T.21S., R.15E., just opposite the Anaconda camp, on National Forest land. Owned at times, or in part, by Parks; Anaconda-Arizona Mining Co.; Altamirano; and the Boulder Mining Co.
Mineralization is lensing quartz-fissure veins containing calcite and barite, and with shoots, stringers, and seams of argentiferous galena and other sulfides and sulfosalts. Veins are often vuggy with mineralization banded or lining vugs. The wall rock is Triassic rhyolite and latite volcanics.
The vein strikes N.62ºW. in crushed tuffaceous andesite. The wall rock on the south side of the vein consists of 16 feet of crushed and brecciated andesite, mineralized with pyrite and chalcopyrite, and constitutes a body of ore. In the vein seams open into small ore lenses about 2½ inches (6.25 cm) wide composed of quartz, barite and sulphides. In the shaft the vein is about 1 foot wide and contains principally banded ore in a quartz-barite gangue.
Workings include a 20 foot long crosscut tunnel containing 65 feet of drift and a 30 foot deep shaft. This group was worked from the early 1870's and intermittently through 1949. The group produced some 300 tons of ore averaging about 5% Pb, 30 oz. Ag/T, 3% Cu, and minor Au.
