Porphyry Copper Deposits Porphyry-type ore bodies are low-grade, high-tonnage accumulations of mineralized rock associated with intrusive magmatic bodies. They are most commonly mined by open-pit methods, and are by far the biggest single orebodies exploited at present. They can range from hundreds to thousands of millions of tonnes of ore Example: Giant Chuquicamata deposit in Chile In India Malanjkhand Deposit in Madhya Pradesh.

They include diorites, monzonites, granodiorites, tonalites alkalic intrusions 1
