Elephants in the Nevada Desert: Carlintype Gold Deposits

Carlintype gold deposits account for 9% of the world's gold production. These deposits are typically low grade, high tonnage and they appear to be largely confined to Nevada, USA.While gold was first discovered in Nevada in the 1870's, it wasn't until 1961 when Newmont discovered and developed the first mine along a structurally faulted area now known as the Carlin Trend.
