Porphyry deposits are copper-rich orebodies formed by precipitation of metal sulphides from hydrothermal fluids released from magmatic intrusions that cooled at depth within the Earth's crust. Finding new porphyry deposits is essential because they are our largest source of copper and they also contain other strategic metals including gold and molybdenum. However, the discovery of giant porphyr...

The Qulong porphyry copper and molybdenum deposit is located at the southwest margin of the Lhasa Terrane and in the eastern region of the Gangdese magmatic belt. It represents China’s largest porphyry copper system, with ∼2200 million tonnes of ore comprising 0.5 % Cu and 0.03 % Mo. The mineralization is associated with Miocene granodiorite, monzogranite and quartz-diorite units, which intrude...

In 2003, Red Chris Development Company started collecting baseline data to support its application for environmental approvals to mine the Red Chris porphyry copper-gold deposit located in northwestern British Columbia, Canada. An extensive geochemical testing program revealed that the majority of the waste rock has the potential to generate acid. However, the presence of significant quantities...

Abstract Porphyry-type deposits are the world’s main source of copper and molybdenum provide a large proportion gold other metals. However, mechanism by which mineralising fluids extracted from magmas transported upwards into ore-forming environment is not clearly understood. Here we use field, micro-textural geochemical techniques to investigate field relationships samples circa 8 km deep cros...

The Poplar copper-molybdenum porphyry deposit, 50 kilometres south-southwest of Houston, is centred near 54 degrees 01 minute north and 126 degrees 50 minutes west. The property is accessible from Houston via 80 kilometres of forest access roads along the Morice River, Owen Lake, Tahtsa Reach, and Poplar Lake. The deposit is situated on the northeast shore of Tagetochlain (Poplar) Lake in an ar...

The task of the tests was to study material composition in order develop a rational technology for enrichment porphyry copper balance and off-balance ores Yoshlik I Kalmakyr deposits obtain collective, copper- molybdenum-containing concentrates, finished products form copper, molybdenum pyrite concentrates. ore samples studied using spectral, chemical, assay, granulometric, phase, gold silver, ...

Abstract Porphyry copper deposits, the principal source of and molybdenum, form at convergent margins. Copper is precipitated from fluids associated with cooling magmas that have formed in mantle evolved mid- to lower crustal levels, before rising toward surface where they saturate exsolve an aqueous fluid copper. Despite advances understanding their formation, there are still underexplored asp...

Abstract Many porphyry molybdenum deposits are hosted in multi-phase plutons, but it is unclear some how these magmas originated and whether the pluton intruded as fractionated or was by new batches of magma. New mapping has clarified field relationships between units White Pine Mo system Little Cottonwood stock, Utah (western United States), including intrusion, Red porphyry, rhyolite dikes, p...

We present high-precision chemical abrasion-isotope dilution-thermal ionization mass spectrometry (CA-IDTIMS) U-Pb zircon and isotope dilution-negative-thermal ionization mass spectrometry (ID-N-TIMS) Re-Os molybdenite geochronology of the world-class Tibetan Qulong porphyry Cu-Mo deposit. The data is used to constrain the timing, duration, and to yield implications for the ore-forming processe...
