Daniel Philco has written: 'An open pit design for the naranjos porphyry copper deposit, Ecuador'. Book Description. Building on the success of its predecessor, this 3rd edition of Open Pit Mine Planning and Design has been both updated and extended, ensuring that it remains the most complete and authoritative account of modern open pit mining available.
Five new chapters on unit operations have been added, the revenues and costs chapter has been substantially revised and updated, and. Porphyry deposits and IOCG’s are the world’s primary source of copper and they account for more than 60% Ecuador book the copper production globally but in addition to copper they also supply % of the world’s molybdenum production, 10 to 15% of global uranium production and a significant proportion of the world’s gold production in short they.

Optimum conditions for development of giant porphyry copper deposits Porphyry Copper Deposit Model porphyry copper deposits generally form in the upper crust (less than 5–km depth) in tectonically active convergent margins and commonly in areas that are elevated and(or) subject to high uplift rates.
MILES Figure D4. Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name.
In later stages, circulating meteoric fluids may interact with the magmatic. The Chaucha porphyry copper deposit, located in the northern Andean Cordillera of Azuay Province, Ecuador, is related to the quartz dioritic Andean batholith intruded in the Paleozoic metamorphics and "Diabase and porphyrite formation" of Cretaceous age.
The intrusive complex is constituted of quartzdiorite, granodiorite, tonalite and quartz Cited by: 1. The images of visible spectrum satellite image of a porphyry mine in the Chilean Andes you can see the open pit and the leach pads as well as the white dust covered areas surrounding the mining operation beyond that you can see the brown and gray volcanics, what you can’t see is the mineralization and the alteration of the volcanics.
The Llurimagua porphyry Cu-Mo deposit (previously Junín) is located in the Intag River Region, west of Cotacachi City in northwestern Ecuador, ~75 km north of Quito (#Location: 0° 19' 1"N, 78° 39' 6"W). Tectonic and Regional Setting The bulk of Ecuador's porphyry Cu±Mo±Au±Ag and porphyry-related epithermal Au±Ag±Cu deposits are of Jurassic and Tertiary (mostly Miocene) age, that define.
The Chaucha porphyry Cu-Mo system is located ~75 km SE of Guayaquil, and 40 km west of Cuenca in southwestern Ecuador, at an altitude of ~ m asl. (#Location: 2° 56'S, 79° 25'W). It is one of a number of Miocene porphyry and epithermal copper-gold deposits that occur in two main clusters, which define two mineral districts in western Ecuador, including Chaucha, Gaby-Papa Grande.
located in central British Columbia and is Canada’s second largest open pit copper mine processing an average of 85, tons per day of ore and producing copper and molybdenum concentrate for sale around the world.

In northern Ecuador, porphyry and epithermal deposits of predominantly Miocene age occur within the Imbaoeste Mineral District, and include the Mt @ % Cu Junin porphyry Cu-Mo deposit (Gribble, ).
Cornerstone has been exploring in Ecuador since and has a portfolio of drill-ready projects there targeting epithermal gold-silver and porphyry copper-gold deposits. An important part of the future valuation of Cornerstone derives from its minority financed interest in the Cascabel copper gold project in northern Ecuador (see Cascabel page).

A mineralized volcanic edifice remains at Chocaya and is believed to overlie a subjacent Bolivian porphyry tin deposits differ from many porphyry copper deposits: in not being susceptible to supergene enrichment; in not possessing known potassium silicate alteration; in being associated with stocks that have the form of inverted cones Cited by: It probably had a long dimension of fifty kilometers.
There was also some porphyry copper skarn mineralization that cropped out in one place and peripheral small vein deposits. One contained lead and zinc, which is diagnostic of porphyry copper systems. Most of what became the Escondida pit – I was just there last month – was covered.
Copper is the primary commodity of economic interest in most porphyry copper deposits, although some deposits with low to very low copper grades are mined principally for their gold (e.g., Çopler.
