Working with government and other partners to mitigate the impacts of our operations and ensure the benefits associated with mining activities are equitably distributed. The basin margin is defined by a sharp, N60-70?W-trending southern margin to a lower sequence of pillowed basalt and underlying sedimentary breccias. pler, Alacer Gold, Turkey: TR review of mineral resource estimates on epithermal property, and review of three TR updates on mineral resources and mineral reserves. Organization: * as of December 2019. Most of the gold is intimately associated with the fine grained quartz-carbon matrix of the altered rock termed "gumbo" by Joralemon (1951). The ore body is described as tabular shaped of unknown dimensions.

Mineralization is both structurally and stratigraphically controlled. Gangue: Covellite These north-east and north-west cross-structures tend not to be displaced, but commonly coalesce with the Getchell Fault Zone, favouring the interpretation that they are largely contemporaneous. No other silver minerals have been recognized except for very rare grains of electrum. 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. .

Gold production resumed in June 1962 and continued to December, 1967, when the mine was closed and the mill dismantled. Geology comments: Bagby and Cline (1991) offer preliminary results from research which indicate that confining pressures on the Getchell ore system varied from approximately 370-430 bars either during, or at some time subsequent to mineralization. In 1981, Conoco purchased the property from Goldfield Corp., but by 1983 had sold the property to First Mississippi for $5 million. In 1995, FirstMiss Gold changed its name to Getchell Gold. Mining feasibility and metallurgical studies were initiated in 1984. The Granite Creek Property is strategically located proximal to Nevada Gold Mines' Turquoise Ridge and Twin Creeks mines at the north end of the Battle Mountain-Eureka Trend, at its intersection . The geometry of the margin and its control on gold mineralization have been refined in the last 12 months during re-logging of close-spaced underground holes and development of a 3D geology model for Turquoise Ridge. Carlins integrated mining operations consist of three open pits and four underground mines. Later basalt eruptions, this green unit, occurred and basalt flowed up to this WNW topographic barrier. - Find out more about subscriptions.

Lone Tree is an open pit operation and was acquired through the Santa Fe merger and began operations in 1991. McCollum and McCollum (1991) indicate that the sense of movement on the Getchell fault is right lateral. The US Bureau of Mines developed a carbon recovery process on site and the mine reopened in 1948 with expanded mill capacity and more underground development, but closed again in mid-1950 when known oxide reserves were exhausted. Peer representatives, known as Opinion Leaders, analyze each story to determine common themes. Gold is micron-scale generally intergrown with arsenical pyrite, which in turn, is encrusted in barren, diagenetic pyrite. Gangue: Realgar. Mine Type: Surface and underground Tertiary: Barium-Barite Long, K.R., DeYoung, J.H., Jr., and Ludington, S.D., 1998, Significant deposits of gold, silver, copper, lead, and zinc in the United States: U.S. Geological Survey Open-File Report 90-206A, 33 p.; 98-206B. Maximum width of ore is 200 ft., with an average width of 40 ft. This ore was to be mined when the pit level was deep enough to provide lateral access. Hydrothermal alteration consists chiefly of decarbonatization accompanied by silicification in the limestone beds. Tertiary: Tungsten The normal faulting caused local instability and the emplacement of multiple sedimentary debris flow breccias. The Twin Creeks mine is an open pit mine that began operations in 1987 and was acquired through the Santa Fe merger in 1997. NGM produces approximately 3.5 million ounces of gold a year. Gangue: Orpiment On May 27, 1999 Placer Dome completed a merger with Getchell Gold Corporation, resulting in Placer Dome owning 100% of the Getchell gold property. These will come mainly from integrated mine planning, optimized mining and processing, cost reductions and the combination of the adjacent Turquoise Ridge and Twin Creeks, which will be operated as a single mine. Conoco leased the property from Goldfield in 1972 and completed exploration including over 300 drill holes. Tungsten production ceased in 1957. in 1960, Goldfield Consolidated Mines Co. purchased the interests in Getchell Mine, Inc. from the estates of Wingfield and Getchell.

The Carlin and Goldstrike mines are both located within the northern Carlin Trend, Nevada, and the pair combined to produce 1.665 million troy ounces of gold in 2020. We mobilized in the last half of 2020 and are still working here. Because of its refractory nature, ore was being processed at Newmont?s Twin Creeks Sage Mill facility. These fluid pressures are greater than those which are normally accepted as epithermal. As of 1951, the gold:silver ratio in bullion ranged from 2:1 to 134:1 and averaged 10:1 for the entire bullion production to that date. Prior to July 1, 2019 Twin Creeks production was included within our Newmont Nevada mine profile. 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. At that time the property consisted of 14,100 acres of fee land and almost 5000 acres of unpatented claims, and reserves at the time of purchase were in excess of 750,000 ounces of gold. Identified synergies are expected to deliver up to $500 million per year over the first five years from 2020, stepping down over time after that.
