The Largest Copper Porphyry Resources

With open pit mining operations beginning at Bingham Canyon in 1906, porphyry copper deposits were the first type of metallic mineral deposit to be mined by largescale, bulk tonnage, open pit mining methods. Economies of scale and advances in technology have made it possible to profitably mine these deposits despite their relatively low ore grades.
