Chapter 8, Porphyry Deposits (with a focus on copper porphyries) Highland Valley, British Columbia Porphyry: textural. porphyry deposit 1. Porphyry copper occurs as large copper deposits centred around stocks of intermediate to acid, porphyritic, igneous rocks. Most occur in Mesozoic and Tertiary orogenic show concentric zones of minerals; for example at Bingham, Utah, there is an inner zone of Cu/Mo and an outer zone of Pb/Zn/ deposits are also characterized by .

Western Canada has been thoroughly explored for porphyry copper deposits. The total estimated copper contained in known deposits is about Mt (based on data), as compared to a 49 Mt mean of estimated copper in undiscovered deposits and a 34 Mt median of estimated copper in undiscovered deposits.

Published: (). Other clay deposits within British Columbia are predominantly glacial, and thus generally contain only un-weathered clay-sized particles instead of clay minerals. Furthermore, the overall quartz diorite composition of the country rocks that underlie the Fraser River drainage basin generally results in Ca-rich bricks which form a generally.
Porphyry copper deposits (PCDs) typically have large alteration haloes that extend several kilometers from economic mineralization providing a geochemical footprint potentially an order of magnitude larger than the deposit. The Paleocene (64±2 Ma) Los Morteros batholith comprises four granodiorite units and hosts four syn-mineralization porphyry units.
These units are Author: Lauren Greenlaw. Other arc-related porphyry Mo deposits in British Columbia, such as Boss Mountain and Davidson, and other deposits around the world, also have reported bismuthinite. Bismuth is considered a secondary commodity at the Koktenkol W-Mo porphyry deposit in Kazakhstan.
Some of B.C.’s largest copper and gold deposits are porphyry deposits. Notable deposits include the Highland Valley Copper mine, KSM, Prosperity, and New Afton. This Google Earth compatible map shows the contained metal(s) for each deposit.

Exploration for these polymetallic Cu-Mo-Au-Ag deposits has produced a database of over 1, Located in northwestern British Columbia within the Stikine terrane, the Red Chris Cu-Au porphyry deposit is hosted in the Late Triassic Red Stock (~ Ma).
The Red Stock is a quartz monzodiorite to monzonite intrusion hosted in the broadly contemporaneous volcanic rocks of the Stuhini Group. Red Chris has features that are characteristic of calc-alkalic and alkalic porphyry deposits. British Columbia is remarkably well-endowed with porphyry deposits.
Associated with episodes of arc magmatism, these deposits include porphyry Cu-Mo ± Au (calc-alkaline) and porphyry Cu-Au deposits (alkaline). The deposits formed in island-arc settings, represented by Quesnel and Stikine terranes, on the fringes of ancestral North America. In porphyry Cu deposits, for example, Cu grades range from % to more than 1% Cu; in porphyry Mo deposits, Mo grades range from % to nearly % Mo.

Drahota, Z. Pertold, M. Pudilová. Book Edition: 1. porphyry copper deposits were the first type of metallic mineral deposit to be exploited by large-scale, 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 Size: KB. So this gives us a start in deciding where to focus our exploration because of the extensive subduction during the tertiary i.e.
in the l, years many porphyry deposits are of this age in other words porphyries are relatively young by geological standards; just put that comment in context although 65 million years sounds a long time ago if the earth’s history was.
The term porphyry is also used for a mineral deposit called a "copper porphyry". The different stages of cooling that create porphyritic textures in intrusive and hypabyssal porphyritic rocks also lead to a separation of dissolved metals into distinct zones.
This process, which occurs primarily when fluids are driven off the cooling magma, is one of the main reasons for the existence in. Porphyry copper deposits carrying more than gm/ton gold are briefly described from northwest Argentina, northwest Pakistan, the Intermontane belt of British Columbia, the Philippines, Sulawesi, Papua New Guinea, Sabah and Puerto Rico.
