US Copper Porphyry Mines Report, Copper porphyry is a form of copper deposit that is often characterized as low-grade, typically with 04% and 10% concentration of copper, and containing other minerals such as gold, molybdenum, and other trace elements in the ore body Copper porphyry deposits are almost always mined in industrial-scale open pit operationsPorterGeo Database, The Ok Tedi porphyry and skarn copper-gold deposits on Mount Fubilan (2053 mASL) are located in the Star Mountains of far western Papua New Guinea, 18 km east of the Indonesian border The pre-mining deposits contained approximately 48 Mt of copper and 490 tonnes of gold (actual metal production + full metal content of reserve)History of the Ok Tedi porphyry copper prospect, Papua New ,, The Ok Tedi porphyry copper-gold deposit in western Papua New Guinea was discovered and tested by a subsidiary of Kennecott Copper Corporation in 1968-1971 Exploration lapsed in 1972-1975 while Kennecott and the government of Papua New Guinea sought agreement on terms which would apply to any future mining operationRegional mineral resources assessment based on rasterized ,, The copper resources of the Wunugetushan copper molybdenum deposit total 2,232,000 tonnes, those of the Badaguan deposit 140,000 tonnes, and those of the Babayi deposit 61,000 tonn These resources are not generated within a single pixel; it is therefore necessary to consider which pixels are able to provide these resourcHIDDEN MINERAL DEPOSITS IN Cu, The Ok Tedi Cu-Au-Ag deposit of western Papua New Guinea also is generally thought of as a major porphyry Cu deposit, yet hosts both porphyry and skarn mineralization Current reserve estimates indicate that the majority of the contained metal within the deposit is hosted by skarns rather than porphyry bodi.
Copper: resource distribution,production and consumption ,, Currently, the explored copper is about 035-057 billion tonnes, and porphyry copper accounts for about 76% of total explored copper Resources distribution in the world is as follows: Area distribution: Copper ore resources are abundant in the world, and mainly distributed in North America, Latin America and central AfricaCadia East Underground Gold and Copper Mine, New South ,, Jan 12, 2021· The ore reserves are 187Moz of gold and 316Mt of copper The exploration activities resulted in increase of about 24 million ounces of gold and 040Mt of copper reserv The total mineral resources as of 2009 were 2,347Mt (including measured, indicated and inferred) graded at 044g/t Au and 028% copperAbout Us | AMD Resources, Imwauna High-Grade Epithermal Au deposit + 8 other known gold prospects Maiden JORC 2012 Inferred Resource of 1196 Mt at 531 g/t Au and 106 g/t Ag for 204,200oz of gold and 407,000oz of silver as at May 2019 Aim to establish oxide reserve at Imwauna by further drilling and trenching in ,Fresh Drilling Results Point to Significant Maiden ,, Total 2143 048 010 138 1,029,000 675,000 29,000 Note 1: Figures in the above table are rounded, reported to two significant figures, and classified in accordance with the Australian JORC Code 2012 for Mineral Resource and Ore Reserve reporting Mineral Resource and Ore Reserve ConfirmationBAGUIO MINERAL DISTRICT THE BAGUIO MINERAL DISTRICT, ,, Bajo de la Alumbrera Porphyry copper 362 13 Ok Tedi Porphyry / Skarn copper-gold 291 14 Sto Tomas II (Philex) Porphyry copper-gold 203 ranked 3rd and 6th largest in the world Rank Deposit Name Deposit Type Moz Au 1 Ladolam (Lihir) Epithermal Low-S veins 239 2 Porgera Epithermal Low-S / Transitional 198.

Exploration & Geology, Porphyry deposits discovered along the coast of South America and North America are examples of porphyry deposits fashioned by a subduction setting During the 1990s, through ongoing studies, the USGS concluded that approximately 350 million tons of copper had been discovered in the USA, and that about 290 million tons remained undiscovered(PDF) Skarns in the Porphyry Copper, For example, the Ok Tedi deposit has several large skarn deposits, but relatively restricted, albeit very intense vein-hosted porphyry Cu-Au mineralisation (Table 1) The enormous Ertsberg skarns in the Gunung Bijih district Irian Jaya (239 Mt of Cu-Au ore) and the Galore Creek deposits (284 Mt of Cu-Au ore) are not known to be directly ,Solaris Resources: Reserves & Resources, The resource is reported using a cut-off of 02% copper Copper equivalent calculations were made for reporting purpos Copper-equivalence calculated as: CuEq (%) = Cu (%) + 333 × Mo (%) + 073 × Au (g/t), utilizing metal prices of Cu - US$300/lb, Mo - US$1000/lb and Au - US$1,500/oz Mineral Resources are not Mineral Reserves and do not ,PorterGeo Database, Phu Kham Porphyry Deposit - Measured + indicated + inferred resources for, TOTAL (025 g/t Au cut-off) - 227 Mt @ 048% Cu, 022 g/t Au, 20 g/t Ag The most recent source geological information used to prepare this summary was dated: 2006 This description is a summary from published sources, the chief of which are listed belowTypes of Copper Deposits in the World | An Investor's ,, Copper deposit grades are usually expressed as a weight percentage of the total rock For example, 1,000 kilograms of copper ore containing 300 kilograms of copper metal has a grade of 30 percent.
