    Gold is not known to occur in minable deposits anywhere in Illinois, so prospecting essentially refers to recreational panning. Gold has never been mined in Illinois, not even as a by-product of other types of mining such as fluorite, zinc-lead, or sand and gravel. Information about panning for gold is available at sites such as Mining Links

    In Virginia, gold was mined from near-surface lode deposits, veins, mineralized zones, and placer deposits. Most of Virginia’s gold mining was in the “gold-pyrite belt”, a nine-mile to sixteen-mile-wide, nearly 140 mile-long northeast trending volcanic-plutonic belt that extends from Fairfax County to southwestern Buckingham County

    Most gold mined in Australia today cannot be seen in the rock, it is very fine grained and mostly has a concentration of less than 5 grams in every tonne of rock mined. The feasibility of mining low concentrations of gold largely depends on the price of gold. Gold is bought and sold every day on international gold markets
