This report contains a revised descriptive model of porphyry copper deposits PCDs, the worlds largest source about 60 percent and resource about 65 percent of copper and a major source of molybdenum, gold and silver. Despite relatively low grades average 0.44 percent copper in 2008, PCDs have significant economic and societal impacts
A recent technical review of the Joshua Copper Porphyry project by well-regarded geologist Mr Robert Perring has identified new and exciting drill targets seeking potential higher grade ones 0.5Cu in the Joshua system which, if discovered, could potentially lead to a significant economic copper porphyry deposit discovery
2016-11-5Copper is a moderately incompatible chalcophile element. Its behavior is strongly controlled by sulfides. The speciation of sulfur is controlled by oxygen fugacity. Therefore, porphyry Cu deposits are usually oxidied with oxygen fugacitiesnbspgtnbspFMQ 2 Mungall 2002 Sun et al. 2015. The problem is that while most of the magmas at convergent margins are highly oxidied, porphyry

2009-10-11The Yulong porphyry copper belt is the most economically significant porphyry copper belt in the region. It is up to 300 km in length and 15 to 30 km wide and hosts one giant de-posit, two large deposits, and two medium-sied deposits, in addition to doens of mineralied porphyry bodies. Although much research has been conducted on the belt e
