Information About Gold - Sources
Gold is found in two major types of deposits.
Lode deposits are deposits where gold is found in cracks and veins in rocks.
These are also called vein deposits.
The second type of gold deposit is called a placer deposit.
Placer deposits are formed by moving water that has eroded gold out of lode deposits.
When the speed of the water in a river slows sufficiently, the heavy gold falls to the bottom and accumulates in the sand of the riverbed.
A third major 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.
