Where does gold come from?

In its natural form, gold is found abundantly as a solid in siliceous rocks, and in the form of granules, nuggets, or even powder in riverbeds. Although many believe gold also exists in vast quantities at the bottom of the world’s oceans, no one has been able to mine this purported gold to date.

Gold producing regions

The yellow metal is one of the rarest elements in the Earth’s crust, and one-fourth of it is found in South Africa. Australia, Russia, Canada, Russia, and the United States are the other leading producers of gold. Nevada, South Dakota, Alaska, Montana, and California are notable gold-producing states in the USA.
