bodies are very large, generally containing from 100 million to several billion tons of copper ore with a copper content of 0.2% to 2.0%. The majority of porphyry copper deposits occur adjacent to subduction zones (i.e. Ring of Fire around the Pacific Ocean), which form along continental margins (i.e. Andes Mountains) and island

Oct 17, 2019· Most of the world’s copper is extracted from a type of mineral deposit called a “porphyry copper”. If you’ve seen a picture of a great big open-pit mining operation odds are that it was a porphyry copper deposit. Some of the biggest man-made holes in the ground are porphyry copper mines: Bingham Copper Mine, Utah, and Chuquicamata in Chile, and two of the largest.

So how do we explore for Porphyry Copper Deposits which are completely covered by barren younger rocks? Well let’s back up a bit, we know that porphyries form under large subduction related volcanoes and that most of these are located under the ring of fire around the subducting pacific plate another fertile subduction zone occurs in Balkans, Turkey, Iran and Pakistan. So this gives us a ...

Porphyry copper deposits and their relationship to felsic intrusions are of considerable economic as well as academic interest. They generally occur near continental margins and in island arcs. Although some conjecture exists as to the ultimate source of transition metals associated with the deposits, a growing body of evidence suggests the metals are principally derived from a magmatic source ...

Porphyry deposits have several characteristics that make them attractive investments for major mining companies – companies which focus on profitability and mine life, not on grade. They can be gigantic – for example, as at 31 December 2011 Escondida had sulphide reserves of 4.9 billion tonnes at 0.71% copper and a staggering sulphide ...
