The Marigold mine is one of the largest gold mines in the United States.[1]
Gold mineralization at Marigold is finely disseminated within sedimentary and metasedimentary rocks, including limestone, siltstone, breccias, meta-basalts and quartzite. The mining operation comprises 11 open pits, eight waste rock stockpiles, three leach pads, two carbon-in-leach processing facilities and a carbon processing and refining facility.[2]
At 31 December 2012 the mine had Proven and Probable Reserves of 294.5 million tonnes of 0.52g/t gold, containing 4.92 million ounces of gold. Another 2 million ounces were in Measured, Indicated and Inferred Resource categories.[1][3]
The mine is located in northeastern Nevada, in eastern Humboldt County, 36 miles east of Winnemucca and four miles south of Valmy.[1] The mine was owned 66.7% and 33.3% by Goldcorp Inc. and Barrick Gold respectively, until February 2014 when Barrick and Goldcorp sold the mine to Silver Standard Resources Inc. for $275 million.[3]
