Deposit: The first discovery in the district in 1891, with the greatest period of development and productivity between 1893 and 1905. Early production was of free mining Au-Ag ore from the shallow oxidized zone. Development work totals nearly 5 miles. The mines are extensively developed by tunnels and drifts that cut at least 15 veins. ; info.src : 1 pub lit; 2 unpub rept; 3 field observ at least 15 veins. Sulfides occur in quartz veins cutting diorite. Biotite-bearing granite porphyry occurs on the dump, and some samples of vein matter contain fragments of a granite porphyry wall (?) most of the veins in the district were reported to trend n W to nnw. Some rocks on the dump are silicified. Quartz veins exhibit some open-space textures. Tourmaline may be present in quartz vein matter, As well As calcite.
Deposit type: Polymetallic veins
Development: Most production 1893-1905 period
Geology: Mineralized area consists of a network of intersecting quartz-pyrite veins covering area 5 mi. Long and 1 1/2 miles wide. The top zone is oxidized, 50-125 feet in depth. The secondary sulfide zone is 50-75 feet in depth below the oxidized zone, and contains some cu, pb, zn with high-grade Au-Ag values. The primary sulfide zone averages 65 feet in depth below the secondary sulfide zone.
