What type of rock is gold most commonly found in?

quartz rockGold is most often found in quartz rock. When quartz is found in gold bearings areas, it is possible that gold will be found as well. Quartz may be found as small stones in river beds or in large seams in hillsides.

How much gold is still undiscovered?

In 2018, U.S. gold mine production totaled about 210 tonnes, down 11 percent from 2017, according to the USGS. The estimated price tag of all that gold was $8.6 billion. The USGS reports that about 18,000 tonnes of gold remain undiscovered in the U.S., with another 15,000 tonnes having been identified but not mined.

Where are gold deposits found?

Gold minerals form in hot rocks in and around volcanoes. Low sulfur, gold-bearing hydrothermal fluids form when hot rocks heat ground water. An example of these low-sulfur fluids are hot springs like those at Yellowstone National Park. The ores of Round Mountain, Nevada, are typical low-sulfur deposits.

Where is gold most commonly found?

Gold is primarily found as the pure, native metal. Sylvanite and calaverite are gold-bearing minerals. Gold is usually found embedded in quartz veins, or placer stream gravel. It is mined in South Africa, the USA (Nevada, Alaska), Russia, Australia and Canada.
