gold in the USA

Gold mining in the United States has taken place continually since the discovery of gold at the Reed farm in North Carolina in 1799. The first documented occurrence of gold was in Virginia in 1782. Some minor gold production took place in North Carolina as early as 1793.

US gold production greatly increased during the 1980s, due to high gold prices and the use of heap leaching to recover gold from disseminated low-grade deposits in Nevada and other states.

In 2007 the United States produced approximately 240 tons of gold, making it the fourth-largest gold-producing nation, behind Australia, South Africa, and China.
