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.
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. The white color of quartz makes it easy to spot in many environments.
How deep is gold usually found?
Hard rock mining Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world’s deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground.

Is gold found in metamorphic rock?
The abundance of gold in crustal rocks is an important constraint on the formation of gold deposits. Gold concentrations in unmineralised igneous, sedimentary and metamorphic rocks range from 0·05 to 20 ppb with average concentrations commonly between 0·5 and 5 ppb.
How can you tell if a rock has gold in it?
To identify gold inside of a piece of quartz, hold a magnet against the rock. If the quartz sticks to the magnet, then it contains iron pyrite, or fool’s gold.
