Alteration: Wallrock Sericitized & Silicified; Gabbro Highly Altered Resembling Limestone

Deposit: The ore occurs As small lenses and pods in a mineralized fault zone. Antimony minerals are most abundant in the NE part of fault zone, but do occur more rarely to s W in fault zone. Some of the richest ore was found near the intersection of the main fault zone and small cross faults that offset the fault zone 1 to 2 feet. First located during world war i. Small quantity of ore was shipped in 1918. Green bros. (averill & frank) worked mine for 3 years (1933-36?) stockpiling 30 tons of ore. Greenmine also worked during the periods 1936-37, 1952-54 and 1962-67. Developed by 4 adits, totaling 410 feet explore a mineralized fault zone 120 feet along strike and 55 feet down dip. Some stopes driven from adits. South of main workings six short adits explore complex fault zone. ; info.src : 1 pub lit; 2 unpub rept; 3 field observ

Deposit type: Polymetallic veins

Development: First located during w.w.i. A small quantity of ore was shipped in 1918. The green brothers (averill & frank) worked the mine for 3 years (1933-36?), stockpiling 30 tons of ore. The green mine was also worked during the periods 1936-37, 1952-54, and 1962-67. Exploration done in 1970's. No activity in 1985.

Early Cretaceous - Middle Jurassic
100.5 - 174.1 Ma



ID: 2746427
Gabbro complex, anorthosite, and albitite

Age: Mesozoic (100.5 - 174.1 Ma)

Description: A large complex of gabbroic rocks forms a series of related intrusions in the northern parts of the Stillwater Range and Clan Alpine Mountains of Churchill County and in the West Humboldt Range of Pershing County (Willden and Speed, 1974). It also may extend into the Trinity Range and Shawave Mountains in western Churchill County (Greene, Stewart, and others, 1991). The complex contains highly differentiated facies near the periphery of the body and more homogeneous gabbro in the interior. Layered rocks near the margins include picrite, olivine gabbro, hornblende gabbro, and anorthosite. The homogeneous rocks consist largely of feldspathic hornblende gabbro and analcite gabbro. The complex is interpreted to be part of a continental Jurassic volcanic arc that is the northern continuation of a Jurassic continental margin arc that extended from the Sonora Desert region in the south to northern California in the north (Dilek and Moores, 1995; Zientek, Sidder, and Zierenberg, 2004). Biotites from several places in the gabbro have been dated by K/Ar and range from 140 to 170 Ma.
