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...

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...

kalchoye copper-gold deposit is located about 110 kilometers east of esfahan province and within the eocene volcano sedimentary rocks. sandy tuff and andesite lava are important members of this complex.the form of mineralization in area is vein and veinlet and quartz as the main gangue phase. the main ore minerals are chalcopyrite, chalcocite, galena and weathered minerals such as goethite, iro...

The effect of sulphuric acid concentration on the kinetics of silver ion cementation on copper in the electrolyte containing 0.5 M CuSO4 was investigated at 25 oC at a rotating cylinder system. The morphology of the silver deposit cemented in the presence or absence of oxygen was studied. Additionally, the influence of the concentration of H ion on the mechanism of the cementation, proposed by ...

Abstract At the Exótica deposit, south of giant porphyry copper deposit Chuquicamata (Atacama Desert, Chile), Cu-rich groundwater seeped out at several locations in open pit (Mina Sur) during sampling 2009–2011. their outflows, these solutions formed blueish and greenish copper-bearing gel-like precipitates. These gels contained atacamite sulfate hydroxides such as devilline, spangolite, posnja...

The Lut Block is a potential porphyry-style mineralized region in Iran including the well-explored Shadan porphyry gold-copper deposit, which has an extensive zone of gold- and copper-bearing stockwork-like sheeted veins. structural setting this deposit key to understanding genesis mineralization. Our field studies show that mineralization occurs as steeply dipping ore bodies along NW–SE transp...
