Locality type:Deposit
Köppen climate type:BSk : Cold semi-arid (steppe) climate


Structure: The deposit occurs along the northern projection of the Carlin Trend, just south of the Midas Trough.

Alteration: The deposit is affected by silicification, argillization, and propylitization. The ore is generally argillized beneath a barren near surface silica cap. The ore is also locally silicified. Tuffaceous rocks are altered to quartz, chalcedony, kaolinite, adularia, and alunite. The andesite is altered to montmorillonite, nontronite, and chlorite, and is crosscut by fractures which contain silica, pyrite, and adularia.

Commodity: Ore Materials: native gold grains. quartz, chalcedony, kaolinite, adularia, alunite, montmorillonite, nontronite, chlorite, calcite, sulfosalts, very fine-grained pyrite Gangue Materials: quartz, chalcedony, kaolinite, adularia, alunite, montmorillonite, nontronite, chlorite, calcite, sulfosalts, very fine-grained pyrite

Deposit: In the sulfide zone, gold is associated with pyrite, marcasite, and trace amounts of chalcopyrite, cinnabar, stibnite, realgar, tetrahedrite-tennantite, and sphalerite. Arsenopyrite, covellite, galena, millerite, and pyrrhotite have also been tentatively identified. In the oxidized zone, gold is associated with goethite and limonite. Gold occurs as discrete native gold particles attached to or included in pyrite and marcasite or their oxidized equivalents. Gold is not encapsulated by silica.

Deposit type: Hot-spring Au-Ag

Development: The opalite at the mine site has been used for toolmaking by native Americans for some 8000 years. Prospecting of the surface mercury showings began at the turn of the century. Between 50 and 150 flasks of mercury were produced from 1915 to 1917. The district was idle from 1918 to 1929. From 1929 to 1943, 1032 flasks were produced from the Butte #1, Butte #2, and Clementine mines. Other mines in the district produced a total of less than 1000 flasks. Auric Metals drilled 100 shallow rotary holes around the Velvet Mine for mercury in 1969-70. APCO Oil drilled a porphyry molybdenum target during the 1970's. Noranda drilled a core hole in 1980 on a uranium target. Homestake explored for a McLaughlin-type gold deposit in 1979-80. Placer Amex drilled several rotary holes in 1982 for Au, Ag, and Hg. In 1984, Kennecott drilled 13 rotary holes for gold in the area. From 1980-86, United States Steel Corp. Completed detailed geologic mapping, rock chip and soil geochemical grids, and geophysical surveys over the Hollister deposit area. Anomalous surface rock chip assays at the extreme southwestern end of the deposit led to drill intercepts of ore grade gold in 1982. USSC completed 123,031 ft. of drilling (195 rotary and 33 core holes), then sought a JV partner or buyer for the property in 1986. Touchstone acquired the property in 1987 and a JV with Galactic was formed later that year. By the end of 1987, Touchstone had completed 240 holes for 127,950 ft. of drilling. A feasibility study was initiated in 1987. Continued drilling identified four mineralized zones that correspond closely with historic mercury mines. Mining commenced in 1990 and continued through 1995. In 2005, Great Basin Gold Ltd.(50%) announced that the access decline at the Ivanhoe Project has now intersected the Gweniver Vein system at a depth of roughly 2,720 feet from the portal.

Geology: The south boundary of known ore is controlled by an arcuate east-trending, near-vertical fault. Siliceous lake bed sinter occurs only north of this fault (probably a caldera margin fault). Alteration is best developed on N-S trending faults. Hg, As, Sb, and Tl all form geochemical haloes that extend above the gold deposit.

Ore(s): The gold is closely related to mercury-bearing sinter and associated silicification that resulted from hot spring activity. The ore is semi-concordant and favors the disconformity between the Valmy Formation and the overlying tuffs and andesite in the lower portion of the volcanic sequence, and fractures in quartzite and argillite of the Valmy Formation. Local gold concentrations are controlled by the intersections of prominent northeast, northwest, and minor east-west striking structures.

Stratigraphic Name: Bates Mountain Tuff; Caetano Tuff; Edwards Creek Tuff; New Pass Tuff; Fish Creek Mountains Tuff; Fraction Tuff; Pancake Summit Tuff; Northumberland Tuff; Shingle Pass Tuff; Darrough Felsite

Description: Welded and nonwelded silicic ash flow tuffs. Aside from alluvium, this unit covers more of Nevada than any other rock, with over 4,000 polygons representing it on this map. It is principally exposed in the central regions of the State. It locally includes thin units of air fall tuff and sedimentary rocks. It includes rocks mapped on the Washoe South, Lyon, Douglas, and Carson Counties maps as the Hartford Hill Rhyolite Tuff (now abandoned); on the Nye South map as the tuff of White Blotch Spring, the tuffs of Antelope Springs, and the tuff of Monotony Valley; in Lander County it is mapped as the Bates Mountain Tuff, Caetano Tuff, Edwards Creek Tuff, New Pass Tuff, tuff of Hall Creek, and the tuff of McCoy Mine; in Lander and Pershing Counties it is the Fish Creek Mountains Tuff; on both of the Nye County maps it is the Fraction Tuff; it also includes the Pancake Summit Tuff, Northumberland Tuff, Shingle Pass Tuff, some outcrops of Darrough Felsite shown to be Tertiary (other outcrops have been shown to be Mesozoic or Paleozoic), tuffs of Moores station, tuffs of Peavine Canyon, tuffs of the Pancake caldera complex, the Stone Cabin Formation, tuff of Saulsbury Wash, tuff of Kiln Canyon, the Tonopah Formation, tuffs of Hannapah, tuff of Bald Mountain, the Needles Range Formation, and the Calloway Well Formation on the Nye North map; in Esmeralda County it is the Kendall Tuff and latite; and in northern Nye and Lander Counties it is the Toiyabe Quartz Latite (now abandoned), and other unnamed units. It corresponds to unit Tt2 on the 1978 State map. It crops out in every county except Clark.
