Book Description
As part of its regular program to provide timely information on domestic mineral commodities, the Bureau of Mines conducted an engineering appraisal of more than 1,300 lode and placer gold deposits in the United States to determine their gold production potential. While these deposits were estimated to contain over 400 million ounces of gold, only 9 million ounces, or slightly more than 2 percent, was found to be producible at $35 per ounce under prevailing mining and metallurgical technologies. The study revealed that any significant increase in available gold in the United States is most likely to come from the discovery of new sources, intensive exploration and development of the more promising known mineralized areas, and development of new or improved mining and metallurgical techniques.

Book Description
Virginia was one of the first major gold-producing states in the U.S., but it has seen only limited and intermittent gold mining activity in the last 70 years. Recent increase in gold prices and other factors have brought renewed attention to mining gold at both new and historical sites in Virginia. This report provides an evaluation of the gold deposits in Virginia, the probable modern mining techniques that could be used at such deposits, and whether existing regulations in the Commonwealth are sufficient to protect air and water quality and human health from potential impacts of gold mining activities. The report concludes that the regulatory framework of Virginia appears to have been designed for operations like crushed stone quarrying and sand and gravel operations, not gold mining. Thus, the current regulatory framework is not adequate to address the potential impacts of commercial gold mining and lacks an adequate financial assurance system, which poses a fiscal and environmental risk to the Commonwealth. Additionally, Virginia lacks opportunities for the public to be engaged in permitting processes and a modern system for review of environmental impacts from potential gold mining projects.
