GOLD By Earle B. Amey Domestic survey data and tables were prepared by Mahbood Mahdavi and Wanda G. Wooten, statistical assistants. The world production table was prepared by Regina R. Coleman, international data coordinator. In 2003, domestic mine production of gold fell to its lowest on December 31. The average for the year was, to the nearest level since 1989. The continuing trend toward consolidation dollar, $365 per ounce. The previous year’s price ranged from among the major gold companies was the primary cause of the 7% about $279 to $357 per ounce and averaged $311 per ounce. decline from the 2002 level. Although gold output fell by 21,000 The 12-month London, United Kingdom, gold lease rates in kilograms per year (kg/yr), the value of the U.S. gold production 2003 remained in the doldrums because the demand for lent gold increased to about $3.3 billion in 2003. Stronger global gold fell more quickly than the reduction in the amount of gold lent to prices and the weakening of the U.S. dollar resulted in an increase the market by central banks. Short-term lease rates continued to in gold value for 2003. The United States dropped to the world’s remain near zero (CRU International Ltd., 2004, p. 31). third leading gold producer (behind South Africa and Australia) Total world mine production of gold was about the same as the after being second since 1991 when U.S. production surpassed level reached in 2002. South Africa decreased its annual output that of the Soviet Union. Nevada accounted for more than 80% after a small increase in 2002 but remained the leading producer of domestic production in 2003. The remaining output came from among more than 80 gold-mining nations, followed by Australia, eight other States. Gold was produced at 50 lode mines, about a the United States, China, and Peru. Identified world gold resources dozen large placer mines (all in Alaska), and numerous small placer at yearend 2003 were estimated to be 100 million kilograms mines (mostly in Alaska and the Western States). In addition, a (Mkg), of which 15% to 20% were byproduct resources; the world small amount of domestic gold was produced as a byproduct of reserve base was estimated to be 90 Mkg, and reserves, 42 Mkg. processing base metals, principally copper.
