Gold mining in Nevada
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. In 2014 Nevada produced 4,940,540 troy ounces (153.668 t), representing 73% of gold in the United States and 6% of the world's production. Total gold production recorded from Nevada from 1835 to 2008 totals 152,000,000 troy ounces (4,700 t), worth over US $228 billion at 2011 prices. Almost all the gold mined in Nevada comes from large open pit mining using cyanide heap leaching recovery.
The Nevada mining industry supported an average of 14,413 direct employees in 2014, with about 65,000 additional jobs related to providing goods and services needed by the mining industry. The average pay for mining industry employees during this time was $88,634 per year, the highest for any employment sector in Nevada.
Although Nevada was known much more for silver in the 19th century, many of the early silver-mining districts also produced considerable quantities of gold. The Comstock Lode produced 8,600,000 troy ounces (270 t) of gold through 1959, and the Eureka district produced 1,200,000 troy ounces (37 t). The Robinson copper mine has produced well over 2,700,000 troy ounces (84 t) gold, along with over 4 billion pounds (1,500,000 tonnes) of copper.
Gold was discovered in the vicinity of Carlin in Eureka County in the 1870s, but production was small. Placer deposits were discovered in 1907, but the deposits were too small to cause much 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. The Carlin mine began producing gold in 1965, but at the price then 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.
The Carlin Trend, part of what is also known as the Carlin Unconformity by geologists, is 5 miles (8 km) wide and 40 miles (60 km) long running northwest-southeast, has since produced more gold than any other mining district in the United States. The trend surpassed 50,000,000 troy ounces (1,600 t) 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.
Dun Glen Mine
The Dun Glen Placer Mine is situated in Pershing County, Nevada, along Dun Glen Creek, which drains from the west side of the East Range Mountains. Reports indicate lode gold was discovered and vein deposits were mined in Dun Glen Canyon during the early 1860s. Chinese miners attempted drift mining of the gold laden placer gravels between 1880 and 1890 with limited success due to the water table. Further exploration of the deposits in the 1920s to 1930’s led to the first mechanized placer operation in 1931.
Golden Fleece Mine (Nevada)
The Golden Fleece Mine, Washoe County, Nevada, near Poeville site, was operated by the Golden Fleece Gold & Silver Mining Company, incorporated on February 2, 1875, which held one patented claim on the site. W. F. Stewart had published a geological report on the mine in 1879, which had an eight-foot vein of ore. The small mining site was located at latitude: 39.584753, longitude: -119.903055 and has received more interest from historical point of view, than for its yield of gold. Several other mines were operating in the Poeville Mining District during 1863 and mid 1880.
Goldfield was discovered in 1902, and began major gold production in 1904. The ore occurs in altered shear zones in Tertiary dacite and andesite. Total gold production through 1959 was 4,200,000 troy ounces (130 t).
All mineral and gold production on public and private lands in Nevada is subject to a Net Royalty payable to the State. The gross proceeds from the sale of minerals minus allowable deductions determine the taxable net proceeds. If the net proceeds from sales by a mine in the taxable year total $4 million or more, the tax rate is 5%. For less profitable mines the tax rate is graduated down to 2%. Miners' net proceeds are also subject to federal corporate income tax of 35%.
Because the NPM tax is an ad valorem property tax, the amount of the net proceeds times the property tax rate goes to the county where the mineral was extracted. Any additional amount of tax paid up to the 5% goes to the State.
In 2013 the Nevada net proceeds royalty raised $162.8 million from gold and silver production, of which the counties received $88.7 million.
