Rawhide, Nevada, 1915
Rawhide, Nevada, 1915

Gold mining in Nevada, a state of the United States, is a major industry, and one of the largest sources of gold in the world. Rawhide Nevada was a town in Mineral County Nevada, approximately 55 miles southeast of Fallon. The United States of America —commonly referred to as the Nevada currently produces 82% of all the gold mined in the United States. Nevada ( is a state located in the western region of the United States of America. [1] Almost all the gold in Nevada comes from large open pit mining and cyanide heap leaching recovery. Open-pit mining, also known as opencast mining and open-cut mining and strip mining, refers to a method of extracting rock or Minerals Heap leaching is an industrial Mining process to extract Precious metals and Copper compounds from Ore. A number of major mining companies, such as Newmont Mining, operate gold mines in the state. Newmont Mining Corporation ( based in Denver Colorado, USA, is one of the world's largest producers of Gold, with active mines in Nevada Active gold mines include those at Jerritt canyon.

Although Nevada was known much more for silver in the 1800s, many of the early silver-mining districts also produced considerable quantities of gold. The Comstock Lode, for instance, produced 8. The Comstock Lode was the first major US deposit of Silver Ore, discovered under what is now Virginia City Nevada on the eastern slope of Mt 6 million troy ounces (267 tonnes) of gold through 1959, and the Eureka district produced 1. Eureka is an unincorporated community in Eureka County, Nevada, in the United States. 2 million troy ounces (37. 3 tonnes).

Goldfield

Goldfield was discovered in 1900, and began major gold production in 1902. Goldfield, an unincorporated community, is the County seat of Esmeralda County, Nevada, United States. The ore occurs in altered shear zones in Tertiary dacite and andesite. The chuprichondira geological time interval covers roughly the time span between the demise of the non- avian Dinosaurs and beginning of the most recent Ice Age, approximately Dacite ( deɪsaɪt) is an igneous, volcanic rock with a high iron content For the extinct cephalopod genus see Andesites. Andesite (ˈændəsaɪt is an igneous, Volcanic rock, of intermediate Total gold production through 1959 was 4. 2 million troy ounces (131 tonnes). [2]

Carlin

Gold was discovered in the vicinity of Carlin in Eureka County in the 1870s, but production was small. Carlin is a town located near the western border of Elko County in northeast Nevada, 23 miles (37 km west of the city of Elko. Eureka County is a County located in the US state of Nevada. As of the 2000 census, the population was 1651 Placer deposits were discovered in 1907, but the deposits were too small to cause excitement. It was not until 1961 that the Newmont Mining Corporation found the large low-grade gold deposit at Carlin that the mining industry began to take notice. Newmont Mining Corporation ( based in Denver Colorado, USA, is one of the world's largest producers of Gold, with active mines in Nevada The Carlin mine began producing gold in 1965, but at the then price of $35 per troy ounce, the ore grade was still too low to cause a rush to northern Nevada. It was not until the gold price shot up in the late 1970s that mining companies rushed to look for similar deposits. [3] The Carlin Trend, part of what is also known as the Carlin Unconformity by geologists, is 5 miles wide and 40 miles long running northwest-southeast, has since produced more gold than the any other mining district in the United States. The Carlin Unconformity or Carlin Trend is a geologic feature in northeastern Nevada which represents a period of erosion or non-deposition likely associated with The trend surpassed 50 million troy ounces (1,555 tonnes) of gold in 2002. The Carlin and other mines along the trend pioneered the method of open-pit mining with cyanide heap leach recovery that is today used at large low-grade gold mines worldwide.

New ore deposits are still being opened along the trend. The South Arturo deposit was discovered by Barrick in 2005. Barrick Gold Corporation () is the largest pure Gold mining company in the world with its headquarters in Toronto, Ontario, Canada The deposit contains an estimated 1. 3 million ounces (40 tonnes) of gold.
