The Basic Economics Of Gold Mining
A better-quality underground gold mine might yield 8-10 grams of gold per ton of ore that is extracted. Marginal underground mines may only yield 4-6 grams of gold per ton of ore. Open pit mines, which have lower infrastructure costs, may be profitable with a yield of just 1-4 grams of gold per ton of ore.
