Meeuwig This report highlights activities through 2001 in metals, production of gold. Only the countries of South Africa and industrial minerals, geothermal energy, and petroleum. Australia produced more gold than the State of Nevada Numerous graphs and charts are incorporated for rapid in 2001. Second to gold in terms of Nevada’s mineral inspection of trends in production and price. Overall value in 2001 was construction aggregate, $158 million. mineral and energy production in Nevada in 2001, valued Electrical power from geothermal energy production in at $2.9 billion, dropped slightly from the previous year. Nevada in 2001 was valued at $87 million. Silver, chiefly Gold production decreased from 8.6 million ounces in a by-product or co-product of gold production, ranked as 2000 to 8.1 million ounces in 2001, the fourth highest the fourth leading mineral commodity in 2001, with a value level in history. Nevada led the nation in the production of $86 million. of gold, silver, and barite and was the only state that The contributions that mining makes to the produced magnesite, lithium, and the specialty clays, economies of Nevada and the U.S. are significant in terms sepiolite and saponite. Other commodities produced in of jobs, commerce, taxes, improvements to the Nevada in 2001 included construction aggregate (sand, infrastructure, and lowering of the U.S. trade deficit. gravel, and crushed stone), geothermal energy, lime, Because of Nevada’s production, the U.S. is a net diatomite, gypsum, cement, silica (industrial sand), exporter of gold, most of which is sold on the international dimension stone, semiprecious gemstones, perlite, salt, market for jewelry and arts and some of which is sold for and petroleum. its superior qualities in computers and other electronics. Nevada ranked second in the United States in terms The U.S. is a net exporter of few mined commodities of value of overall nonfuel (excluding oil, gas, coal, and and a net importer of many. Among the major mined geothermal) mineral production in 2001 (according to the products in Nevada, the U.S. relies upon imports for barite U.S. Geological Survey, Mineral Commodity Summaries (87% of total U.S. consumption from imports, according 2001, http://minerals.usgs.gov/minerals/pubs/mcs/). to the U.S. Geological Survey, used primarily to prevent California, with its large population and commensurate blowouts in oil and gas drilling), silver (44%, used in demands for construction raw materials, was first; Texas, photographic and other applications), copper (31%, used also a populous state and major producer of construction primarily to conduct electricity), and gypsum (25%, used raw materials, was third; and Arizona, the nation’s leading in wallboard). Our exports of gold help offset the copper producer, was fourth. staggering U.S. trade deficit (difference between imports Nevada’s production of gold, valued at nearly $2.3 and exports of goods and services), which amounted to billion, was 76% of the U.S. total and helped make the $344 billion in 2001 (according to the Department U.S. the second leading gold producer in the world in of Commerce, Bureau of Economic Analysis, 2001. Nevada alone accounted for 10% of world www.bea.doc.gov/bea/).
