U.S. gold mine production increased 6% in August, the U.S. Geological Survey has reported.
Meanwhile, year-to-date mined copper output was 10% higher in July of this year that during the same period of last year, according to the USGS.
August production of gold by U.S. mines was 20,700 kilograms (665,520 troy ounces), up 6% from 19,600 kg (630,154 oz) for August 2012. Nevada led August 2013 output with 14,200 kg (456,540 oz) of gold, followed by other states at 2,880 kg (92,594 oz) and Alaska at 2,490 kg (80,055 oz).
For the period from January through August of this year, U.S. gold mines yielded 152,000 kg (4,886,913 oz) of gold with Nevada mines producing 113,000 kg (3,663,034 oz), followed by Alaska mines at 20,600 kg (662,305 oz) and other states combined at 18,200 kg (585,143 oz).
Daily gold production for U.S. mines in August 2013 was 669 kg (21,508 oz), according to the USGS.
Year-to-date U.S. copper mined production through July was 10% higher at 708,000 metric tons that during the same period of last year, the Geological Survey reported.
U.S. mines reported 106,000 tonnes of copper production in July 2013, up from a total of 88,400 tonnes during the same period of last year. Arizona led U.S. copper output with 68,200 tonnes in August 2013, while other states contributed 37,900 tonnes.
The U.S. year-to-date smelter and electrolytic refinery production through July were 15% and 10% higher, respectively, than that in the same period of 2012, said the Geological Survey.
Preliminary data from the International Copper Study Group estimated world copper mine production at an estimated 8.7 million metric tons in the first half of this year, an 8.8% increase compared with production in the first half of last year. The ICSG reported that refined copper production exceeded consumption by 18,000 metric tons during the first half of this year.
