Porphyry copper deposits ppt. Here let's understand the geology of porphyries and iron oxide copper gold deposits or IOCG as they are known. These are somewhat the giants of the ore deposits world. As a mining interested learner, the geology of porphyry copper deposits is vital to your education.. Now in the first Exploration Geology Course I discussed how because our current mining ...
The locations of 88 porphyry and related copper and molybdenum occurrences are shown on a 1:1,000,000-scale topographic base map of Nevada. In addition to porphyry copper the map includes copper skarn deposits, copper-bearing high-level alteration zones, and …
Porphyry Cu and porphyry Mo deposits are large to giant deposits ranging up to >20 and 1.6 Gt of ore, respectively, that supply about 60 and 95% of the world's copper and molybdenum, as well as significant amounts of gold and silver. These deposits form from hydrothermal systems that affect 10s to >100 km 3 of the upper crust and result in ...
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 the district (Kuelmer, 1954).
When it comes to porphyry deposits, size counts. These multigenerational monsters are responsible for ~60 per cent of the world's copper, most of its molybdenum, and significant amounts of gold and silver. Their easy-mining large volumes make up for the low grades, typically between 0.3 per cent to 1 per cent copper equivalent. But these […]
Porphyry (/ ˈ p ɔːr f ɪ r i / POR-fih-ree) is a textural term for an igneous rock consisting of coarse-grained crystals such as feldspar or quartz dispersed in a fine-grained silicate rich, generally aphanitic matrix or groundmass.The larger crystals are called phenocrysts. In its non-geologic, traditional use, the term porphyry refers to the purple-red form of this stone, valued for its ...
The Cadia, Grasberg, Oyu Tolgoi, Kalmakyr, Pebble Copper and Bingham deposits in red symbols are the six largest Au-rich porphyry Cu deposits based on Au endowments.
Porphyry copper deposits, which are associated with igneous intrusions, yield about two-thirds of the world's copper and are therefore the world's most important type of copper deposit. Large copper deposits of this type are found in mountainous regions of western North America and in the Andes Mountains of South America.
Porphyry copper deposits are one of the most important sources of copper and molybdenum, and are also major sources of silver, gold, and tin.In addition, porphyry …
Porphyry Copper Opportunity The Opportunity The East Tintic district has historically been recognized as an area prospective for large porphyry style Cu-Au-Mo mineralization, displaying many similar hallmarks to and having a larger surface geochemical footprint than the area surrounding Kennecott's (RTZ) iconic Bingham Canyon Cu-Au-Mo ...
Porphyry copper deposits are typically very-low grade with between 0.4 and 1% copper. The main mineral is chalcopyrite, which is finely disseminated through the host porphyritic rocks. The only reason these ore bodies are economic is because porphyries are huge, with hundreds of millions of tonnes available in a fairly low-cost mining setting.
World Copper has laid claim to four copper porphyry targets, one with estimated resources, significant soluble copper mineralization, and exciting potential to expand the resource base. The World Copper team has a unique skill in navigating the mining sector within Chile, with some members having worked in the country for more than 40 years and ...
About the Mocoa Porphyry Copper-Molybdenum Deposit . The Mocoa deposit is located in the department of Putumayo, 10 kilometres from the town of Mocoa. It …
Porphyry copper deposits are also important sources for other metals, including molybdenum, gold and silver. Minor amounts of rhenium, tellurium, arsenic, zinc and platinum group elements are also present in elevated concentrations within these systems and are recovered at some mining operations. ...
The Dexing porphyry copper and Yinshan polymetallic deposits in Dexing City, southeastern China are both giant porphyry ore systems. Located 15 km apart, they formed synchronously and share a similar magma source and metallogenic evolution, but their metal endowment, dominant rock types, and alteration assemblages differ significantly. In this contribution, we …
Porphyry copper deposits are the world's largest sources (approximately 60%) of copper and the major sources of molybdenum and gold (John et al., 2010). Most porphyry copper deposits worldwide are related to calc-alkaline felsic magmas in subduction zones of convergent plate margins (Cooke et al., 2005, Richards, 2003, Sillitoe, 1972).
The Practice Lead- Porphyry Copper will define and influence leading practice in the understanding and application of mineral systems to porphyry copper deposits, lead research in this field, and provide technical guidance to all Metals Exploration activities focused on porphyry copper deposits globally.
Porphyry Copper Systems* RICHARD H. SILLITOE† 27 West Hill Park, Highgate Village, London N6 6ND, England Abstract Porphyry Cu systems host some of the most widely distributed mineralization types at convergent plate boundaries, including porphyry deposits centered on intrusions; skarn, carbonate-replacement, and sediment-
This report contains a revised descriptive model of porphyry copper deposits (PCDs), the world's 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 ...
Porphyry copper deposits are generally composed of a "plug-like" igneous intrusion – a large magma body that is emplaced beneath a volcanic system. On average these deposits can have a vertical and horizontal extent of 1-2 km and can range from tens of …
A probabilistic mineral resource assessment of undiscovered resources in porphyry copper deposits in the Tethys region of western and southern Asia was carried out as part of a global mineral resource assessment led by the U.S. Geological Survey (USGS). The purpose of the study was to delineate geographic areas as permissive tracts for the occurrence of porphyry copper deposits at …
Geology of a major new porphyry copper center in the Superior (Pioneer) District, Arizona. Manske, S.L., and Paul, A.H., 2002, Geology of a major new porphyry copper center in the Superior (Pioneer) District, Arizona: Economic Geology, v. 97, no. 2, p. 197-220. Read more. about Geology of a major new porphyry copper center in the Superior ...
Porphyry copper deposits in the district, exposed in the Singatse Range, are associated with granite prophyry dike swarms emanating from a deep granite cupola emplaced into an earlier quartz monzodiorite batholith. Based on U-Pb dates, the batholith and its related granite dike swarms and hydrothermal systems had a total life span of less than ...
Porphyry copper deposits result from the complex interactions and feedbacks of many processes. Owing to the complexity, a succinct definition that includes the essential attributes of this deposit class is elusive. Consequently, this descriptive model uses a working definition of a porphyry copper deposit.
Porphyry deposits are very large, polymetallic systems that typically contain copper along with other important metals. Much of today's mineral production depends on porphyries: 60% of copper, 95% of molbdenum, and 20% of gold comes from this deposit type.
2 Libero Copper & Gold Corporation is pleased to announce that the company has made 32 mining title applications totaling 103,578 hectares covering a significant portion of the Jurassic porphyry ...
Porphyry deposits produce approximately 60% of the world's copper. Most of these deposits lie in the Pacific Rim, also known as the Ring of Fire, an arc that stretches from Papua New Guinea to the southern tip of Chile. The copper is contained within roughly cylindrical granitic bodies that are remnants of the magma core beneath volcanoes.
This was the start of the porphyry era, which continues to this day. Bingham Canyon was the first low grade porphyry copper deposit off the rank. Operations commenced in 1905 on a reserve of about 40 million short tons at the then very low grade of 1.98% copper. Today the median copper grade for porphyry mines is around 0.5% and still falling.
