Some deposits were discovered and mined out prior to 1930, but new resources and/or reserves were discovered on the site afterwards. The resources are classified as gold or silver according to which commodity has the higher value based on a gold:silver ratio of 1:64. This ratio is based on the average gold and silver prices between 2000 and 2004: $328 per ounce of gold and $5.08 per ounce of silver (U.S. Geological Survey Mineral Commodity Summaries, 2005). Several base-metal and industrial-mineral deposits are also shown because they contain significant gold and/or silver. The major commodity of these particular deposits is given in parentheses. The sources of information include published and unpublished literature, company reports, NBMG Mineral Industry series and county Bulletins, the Internet, and individuals working in the mining industry.
