For the first half of 2012, the agency report a total of 113,000 kg (3,633,034 oz)of U.S. gold production, down 3 percent from the same period of last year. Of that January through June 2012 production, 85,900 kg (2,761,750 oz) were mined in Nevada, while 12,300 kg (395,454 oz) were mined in Alaska, according to the USGS.

Beginning in 2019, Bingham Canyon is expected to have an average annual output of 5,750 kg (184,867 oz) of gold, 180 kt (198,000 st) of copper, and 13.8 kt (15,200 st) of molybdenum.
