One of the largest industries in Nevada is gold mining and the majority of those mines are in the Humboldt River Basin on the Carlin Trend. Gold mines in Nevada produce close to 80 percent of all the gold in the U.S. and are the 4th largest in the world. In 2010, Nevada mines produced 5,338,559 ounces of gold (Nevada Division of Minerals).
