Gold Deposits and Their Geological Classification

2016-11-20  2. Geological Survey of Canada, Ste-Foy, Québec, Canada ABSTRACT Classifications of ore deposits provide essential frameworks for designing exploration strategies, evaluating prospects, and performing resource assessments of selected areas. A rational geological classification of the commonly recognized lode gold

2010-9-19  Since the British Gold Standard was established in 1717, the price of gold generally has been fixed officially, and thus it has tended to remain stable. The U.S. Congress in 1792 adopted a gold standard of $19.39 per troy ounce, which lasted to 1834 when the official price was set at $20.67.

Gold. Gold reserves at the beginning of 1988 was estimated at 101.6 million metric tons (MT), equivalent to about 240 MT of gold metal. Between 1988 and 1994, a total of 27.7 million MT of gold ore, containing about 36 MT of metal was extracted. On the average, this is equivalent to an annual extraction of 3.9 million MT of gold ore.
