Nevada Exploration Inc. announced the company has added economic geologist Nancy Richter to the company's board of directors as Nevada Exploration pursues exploration at its South Grass Valley. Gangue: Laffittite Gangue: Scheelite 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. Both programs are about employee engagement by identifying hazards in the work place and then management providing support to correct those hazards. Newmont is committed to increasing educational opportunities, not only in the mining sector, but also in other disciplines critical for the ongoing sustainability of our economy and way of life. The project is expected to facilitate an increase in the mining rate to 1.4Mt/a.

We interpret this buried WNW fault to be linked to underlying basement rift faults that formed during the Proterozoic. Metals Mined: Gold Prospectors Edward Knight and Emmet Chase discovered gold in 1933 and located the first claims in 1934. Organization: The Getchell Mine is an underground gold mine in the Potosi Mining District of Humboldt County, Nevada, on the east flank of the Osgood Mountains, 35 miles northeast of Winnemucca. We take our responsibility for preserving the regions natural resources very seriously. In 1995, FirstMiss Gold changed its name to Getchell Gold. Turquoise Ridge Complex A historic mine and mill combined in the joint venture into a Tier One i operation i A Tier One Gold Asset is an asset with a reserve potential to deliver a minimum 10-year life, annual production of at least 500,000 ounces of gold and total cash costs per ounce over the mine life that are in the lower half of the . Conoco subleased the property from 1975 to 1978 to General Electric Co. who conducted tungsten exploration along the margins of the Osgood Stock. The main deposit is confined to a zone nearly 7000 ft. long at the northern end of the Getchell fault zone. Role: Host Mines: Long Canyon. By mid-1985, the Getchell property had increased the area of unpatented claims to 13,900 acres. The basin margin was originally identified by Placer Dome Exploration geologists in 1999. PLACER DOME has given the 300,000-oz/year project the green light. The Turquoise Ridge Mine is located approximately 1 km to the east of the Getchell Main Pit; UTM is to center of Main Pit, which has encompassed earlier South and Central pits. Within ore zones, gold occurs as native grains that range in size from <1 micron to nearly 1 mm, with smaller grains more abundant than larger grains. . * as of December 2019. We are committed to the development of meaningful and measurable programs within our communities through volunteer efforts and financial support. Date of First Production: 1964 You can email the site owner to let them know you were blocked. Turquoise Ridge's production forecast for 2005 calls for an increase in Placer Dome's share of production to 150,000 ounces and its cash and total costs per ounce forecast is $310 and $350, respectively. The Twin Creeks property is comprised of the Twin Creeks mine and the Turquoise Ridge Joint Venture. All of Newmonts Nevada sites, facilities and projects are subject to environmental regulations. Age Young: Late Cambrian > Granitoid Similar relationships are seen in the northern Carlin trend. These teams also test their preparedness, skills and speed against industry peers in mine rescue competitions across the country. 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.

Nevada, County: Within ore zones, gold occurs as native grains that range in size from <1 micron to nearly 1 mm, with smaller grains more abundant than larger grains. Age Old: Middle Cambrian, Ore: Gold The mill started up on oxide ore in February, 1989. Prior to July 1, 2019 Twin Creeks production was included within our Newmont Nevada mine profile. They also appear to exert a major control on ore deposition. The themes are further analyzed to develop three to four key Vital Behaviors that, when followed, will prevent injury and loss. Please include what you were doing when this page came up and the Cloudflare Ray ID found at the bottom of this page. 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. The Long Canyon mine is an open pit mine that began operations in 2016. Gangue: Guerinite Age Young: Late Cretaceous, Role: Host Deep exploration shows that the mineralization persists at least 1 km down-dip on the Getchell fault system and also occurs along the parallel Village fault. Nevada Gold Mines is a joint venture between Barrick Gold Corporation (61.5%) and Newmont Goldcorp Corporation (38.5%), combining their significant assets across Nevada to create the single largest gold-producing complex in the world and realize the full potential of these mines through synergies and best-in-class operational improvements.

Gangue: Molybdenite Age in Years: 90.000000+- Production will continue to increase in 2005 as mining moves from the topcuts to the more productive undercuts. Turquoise Ridge Underground currently has two roadheaders in operation. The ore mined is composed of sphalerite, chlorite and scheelite with waste material consisting primarily of realgar. Modeling of low-grade (~0.01 opt Au) shows NNW-elongated shapes below and within the breccia, suggesting Getchell fault parallel structural fabrics served as conduits for upwelling auriferous hydrothermal fluids. County: Humboldt This ore was to be mined when the pit level was deep enough to provide lateral access. Igneous dikes and portions of the main stock are altered such that plagioclase is altered to sericite and kaolinite and biotite is altered to sericite, chlorite, and pyrite. Gold is associated with arsenic, mercury, and to a lesser extent antimony, and commonly with pervasive decalcification, silicification and carbonaceous alteration. Gangue: Pyrite In 1938, the mining rate was about 500 tpd of oxide ore and 150 tpd of sulfide ore. Sulfide ore was roasted at 1500 degrees Fahrenheit for one hour and fifteen minutes preparatory to cyanidization. Sedimentary Rock As of July 1, 2019 Barrick entered into a 61.5:38.5 joint venture with Newmont, concerning their Nevada based assets.

Many of our employees are involved in regional environmental and resource conservation programs. Land ownership: Private 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. Gold production has been suspended since July 1999 and the property is on care and maintenance. 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. It employed more than 420 persons. Tertiary: Thallium Cyprus Mines formed a joint venture with Goldfield in 1970, with Cyprus as operator. 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. Gold mineralization is found in a number of different rock types generally at the intersection of a number of high-angle and low-angle fault sets. Mine rescue contests are designed to sharpen skills and test the knowledge of team members who would be called on to respond to a mine emergency. Nevada Gold Mines (NGM) is a joint venture between Barrick (61.5%) and Newmont (38.5%) that combined our significant assets across Nevada in 2019 to create the single largest gold-producing complex in the world. Gold production from Nevada was higher than any other U.S. state, 4,632,690 troy ounces (144,090 kg) in 2020 (a decrease of 4.8% on 2019), accounting for 76% of gold produced in the United States and 4.5% of the world's production. Heap leaching continued beyond this date using oxide reserves from the Summer Camp orebody discovered in 1985.

Phoenix is an open pit operation and was acquired through the Battle Mountain Gold merger and began operations in 2006. 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. This syn-sedimentary faulting was further supported by logging of close-spaced underground drill hole fans. Mining feasibility and metallurgical studies were initiated in 1984.
