  Gold Mining Methods

  Today, gold is extracted in hardrock mines that directly mine the source rock, or "lode" of gold, where it was originally deposited by geochemical processes. Most ore accessed this way today contains only microscopic grains of gold, and it takes tons of rock to produce ounces of gold. Hardrock mines can be either underground mines or strip mines, and are usually more .
