2. What is a Porphyry? What is a Porphyry Copper Deposit?

3. Porphyry (por’phy-ry) An igneous rock of any composition that contains conspicuous phenocrysts in a fine-grained groundmass.

5. Porphyry

6. Porphyry Copper Deposit A large low- to medium-grade deposit, of primarily of pyrite, chalcopyrite and molybdenite with characteristic concentric zoning of mineralization and alteration around calc-alkaline porphyritic intrusion (typically quartz monzonite to granodiorite)
