Porphyry Copper Deposits | Geology for Investors

Porphyry Copper Deposits | Geology for Investors

Porphyry copper deposits are typically very-low grade with between 0.4 and 1% copper. The main mineral is chalcopyrite, which is finely disseminated through the host porphyritic rocks. The only reason these ore bodies are economic is because porphyries are huge, with hundreds of millions of tonnes available in a fairly low-cost mining setting.
