A tabulation of grade and tonnage of porphyry copper ores of the region has been published by Gilmour (1982) and sum marized by Titley and Anthony (1989) and Titley (1994). Re serves in 1989 have been listed by Beard (1989). Production figures summarized for 45 porphyry copper deposits in the
Oct 30, 2018· A detailed investigation into the source of Alacran mineralization has led to the identification of a potential porphyry coppergold source located immediately west of the Alacran Deposit.
An important feature of the porphyryepithermal mineral system is the telescoping of different deposit types, for instance porphyry CuAuMo deposits and epithermal deposits of various types. Sources of fluid, metals and energy
Porphyry copper deposits sometimes form during the solidification of stocks of relatively oxidized magma of intermediate composition. Most workers have assumed oreforming systems have special chemical attributes, but none has been found that is useful to guide exploration efforts.
Introduction PORPHYRY Cu systems are defined as large volumes (10−>100 km3) of hydrothermally altered rock centered on porphyry Cu stocks that may also contain skarn, carbonatereplacement, sedimenthosted, and high and intermediatesulfidation epi .

tion from a recognized porphyry deposit did not begin until 1955, from the Copper Mountain deposit at Mines Gaspé, Quebec. Copper production from porphyry deposits increased rapidly in the 1960s and early 1970s with the development of deposits in British Columbia such as Bethlehem and Lornex in the Highland Valley district,
Porphyry copper deposits are the world's most important source of Cu but other elements such as Mo, Au, Ag, Re, Sn, W, PGE, In, Se, Te, Bi could be recovered from these deposits as subproducts or coproducts of Cu extraction (Berger et al., 2008; Sinclair, 2007).
Participants on this field trip to the Ordovician porphyry coppergold province of central NSW will gain a brief overview of the Macquarie Volcanic Province that hosts the operating Cadia, Northparkes and Cowal mines, and of these deposits themselves. The many unusual features of this province have
PORPHYRY COPPER MINERALISATION OF WESTERN USA Allan VIEPS, The University of Melbourne, Victoria 3010, Australia Porphyry copper deposits of western USA are very large low grade deposits dominated by disseminated Cu mineralisation but commonly with appreciable Mo and Au. Many deposits began as gold camps.
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 deposit should occur in .
porphyry copper deposits were the first type of metallic mineral deposit to be exploited by largescale, bulk tonnage, open pit mining methods. Economies of scale and advances in technology have made it possible to profitably mine these deposits despite their relatively low ore grades.

Porphyry copper deposits are copper orebodies which are associated with porphyritic intrusive rocks and the fluids that accompany them during the transition and cooling from magma to rock. Circulating surface water or underground fluids may interact with the plutonic fluids.
Porphyry copper deposit densities vary from 2 to 128 deposits per 100,000 km 2 of exposed permissive rock, and the density histogram is skewed to high values. Ninety percent of the control areas have densities of four or more deposits, 50 percent have densities of 15 or more deposits, and 10 percent have densities of 35 or more deposits per 100,000 km 2 .
