Summary. Historically, the majority of gold was mined from quot;placer depositsquot;, where gold has settled out of an existing or ancient waterway downstream of where nuggets had eroded out of rock outcrops.Some early miners also used an early form of hardrock mining, digging solid veins of gold out of rock, where mineralized water had deposited it over thousands of years.
