San Jorge is a porphyry copper deposit (PCD). It is hosted by the Carboniferous clastics, a felsic porphyry intrusive, dacitic dikes, and a tourmaline breccia. The formermost is host to highergrades of hypogene mineralisation. The tourmaline breccia and dacite dikes host a volumetrically small portion of the deposit.

These deposits are called porphyry copper deposits. In addition, search for rocks that are green or pieces of ore that have green flecks. The green hue is characteristic of copper. Remove samples of the rocks and take them back to the lab for testing.
The Jebel Ohier porphyry copper deposit bears many similarities to well documented Phanerozoic analogues elsewhere in terms of (1) the mapped style and zonation of hydrothermal alteration (, proximal Ksilicate–dominated, to sericitic, to distal propylitic alteration), (2) the occurrence of intense Cubearing A and Btype vein stockwork, as well as sulfideonly Ctype veins, anhydrite veins, and .
Jul 24, 2012· The Dexing ore deposit, Jiangxi Province, is the largest porphyry copper deposit in China. Controversies exist regarding the oreforming source of this deposit. We have conducted Pb isotope analyses of pyrites from the Tongchang and Fujiawu mines.

The company said an analysis of multielement geochemical data by industry expert Dr Scott Halley provides strong geochemical evidence that a coppergold porphyry intrusion may be ...
Santiago has a Masters Degree from The Mineral Deposit Research Unit at the University of British Columbia in Canada, where he studied the proliferous CuAu porphyry belt hosted in the Nicola/Takla group. This included the Copper Mountain, Mount Polley and Mount Milligan mines and the Woodjam deposit.

Porphyry deposits are the most important source for the metals copper, molybdenum and gold (more than 50% of the globally mined copper comes from porphyry systems). Additionally, significant quantities of other metals are mined from porphyry deposits, such as tin, silver, lead and zinc .

Porphyry deposits are the world's principal resources of Cu, Mo, and Re, and are major resources of Au and Ag. Since 1905, more than 700 articles concerning porphyry deposits have been published by the Society of Economic Geologists in its various publications (Economic Geology,
Preservation of what is considered the first documented porphyry CuAu deposit in the NE African portion of the Arabian Nubian Shield can probably be related to the accretion of the magmatic arc to a stable continental margin within a few million years of mineralization, thus enabling the deposit to escape excessive uplift,...
Jan 19, 2013· Porphyry copper and molybdenum deposits have a disturbingly phallic shape; a tall, rough cylinder capped by a bellshaped zone of mineralisation. And they are pretty big, the largest at Bingham Canyon in Utah, USA once having been ~ km tall and km wide, with a 2 km, bellshaped zone of mineralisation affecting the intrusion and its surrounding country rock.
Preservation of what is considered the first documented porphyry CuAu deposit in the NE African portion of the Arabian Nubian Shield can probably be related to the accretion of the magmatic arc to a stable continental margin within a few million years of mineralization, thus enabling the deposit to escape excessive uplift, erosion and structural dismemberment.

of copper deposit, the socalled porphyrytype, that is estimated to contain nearly 50% of the worlds' preserved of this strategic metal (Gustafson, 1978; Guilbert and Park, 1986). Estimated preserved of the Haib deposit are about one billion tonnes of very low grade copper ore (~ % Cu), with traces of Mo and Au (Minnitt, 1986).
Jul 28, 2014· Approximately 60% of the world's copper and 95% of the world's molybdenum is sourced from porphyry copper deposits. Distribution Porphyry copper deposits are distributed along 'convergent' tectonic margins, where oceanic tectonic plates subduct down into the earth's mantle.
This is an ore from a zone of Copper Porphyry which was located in southeastern New Brunswick. The overall grade of the ore was assayed at .35% copper and 600ppb AU or gold. This deposit is actually a project which myself and another prospector have been looking at over the last year.
