Gangue: Cassiterite We mobilized in the last half of 2020 and are still working here. Hydrothermal alteration consists chiefly of decarbonatization accompanied by silicification in the limestone beds. The low-angle faults and associated folds are the result of Devonian and Permian-age compressional events and the higher angle faults and fracture sets formed during Tertiary extension. Our initial scope was to install high capacity ground support around one of the third shaft stations prior to sinking efforts reaching this station. extensional event, basalt erupted and flowed up to the WNW-trending topographic barrier. Nevada Gold Mines Executive Managing Director Greg Walker said operating the Turquoise Ridge and Twin Creeks mines as one one entity under the joint venture is resulting in a synergy savings of . The older east-west fault and joint sets produce graben structures throughout the mine area, some of which drop the Valmy Formation down to become juxtaposed with the Comus Formation.

This ore was to be mined when the pit level was deep enough to provide lateral access. Because of its refractory nature, ore was being processed at Newmont?s Twin Creeks Sage Mill facility. Our employees devote countless hours to volunteerism in Nevada communities. Later basalt eruptions, this green unit, occurred and basalt flowed up to this WNW topographic barrier. Gangue: Cinnabar Joralemon (1951) observed microscopic metallic grains in the Getchell ore that he concluded were native silver, although the particles were so small that conclusive chemical tests were not possible. Production of oxide open pit ore commenced at the nearby Turquoise Ridge mine in 1991 and in the same year, an underground orebody adjacent to the pit area.

The Twin Creeks operation produced 453,000 ounces of gold in 2016, and at December 31, 2016, reported 4.9 million ounces of attributable gold reserves. Gold is associated with arsenic, mercury, and to a lesser extent antimony, and commonly with pervasive decalcification, silicification and carbonaceous alteration. Gold production resumed in June 1962 and continued to December, 1967, when the mine was closed and the mill dismantled. The Turquoise Ridge Underground deposit is a typical Carlin-type deposit and is characterized by structurally and stratigraphically controlled, sediment-hosted, replacement deposits containing micron-sized gold. The underground mines include Leeville , which is a shaft mine , along with Chukar, Pete Bajo and Exodus , which are portal mines. Initial production took place in 1938 and overall output was considered to be large size. McCollum and McCollum (1991) indicate that the sense of movement on the Getchell fault is right lateral.
