Veins of gold in bedrock are called "lode" deposits, and "placer" deposits are concentrations of gold that accumulated in unconsolidated sediments.
Another source of gold is as a by-product of copper and silver mining. Gold is so valuable that it is worth the effort to recover even minute amounts from copper and silver ore. It is estimated that the total amount of gold yet to be removed from the Earth is 100,000 tons.
