GEOLOGY AND EVOLUTION OF THE COPPER FLAT PORPHYRY …

The Copper Flat porphyry copper deposit in the northern part of the Hillsboro district was discovered in 1975 (Castellano et al., 1977; Dunn, 1982, 1984), although alteration and mineralization in the area suggested to earlier geologists that a porphyry copper …

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.
