SummaryPlacer MiningHardrock LODE MiningImpactsGold Mining in Alaska

Historically, the majority of gold was mined from placer deposits, 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. Today, gold is extracted in hardrock mines that directly mine the source rock, or lode of gold, where it was originally deposited by gSee more on
