In comparison, the southern subzone contains numerous skarn–porphyry copper, molybdenum, gold, tungsten and antimony deposits. The middle subzone hosts the majority of the mineralization (in the form of both skarn–porphyry and Fe-oxide–apatite deposits) within the MLYRMB and is split into seven individual ore districts ( Chang et al ...

Accompanied by hypabyssal emplacement of high-potassic alkali-rich porphyries," paired " Cenozoic intracontinental porphyry copper-molybdenum-gold belts,controlled by large strike-slip faults,occurred on the eastern margin of the Qinghai-Tibet Plateau formed by India-Asia collision.Of the two metallogenic belts,the west belt is the Jomda-Markam …

January 1, 2016. Porphyry Cu and porphyry Mo deposits are large to giant deposits ranging up to >20 and 1.6 Gt of ore, respectively, that supply about 60 and 95% of the world's copper and molybdenum, as well as significant amounts of gold and silver. These deposits form from hydrothermal systems that affect 10s to >100 km 3 of the upper crust ...

6.5 billion tonnes in the combined Measured and Indicated categories at a grade of 0.40% copper, 0.34 g/t gold, 240 ppm molybdenum and 1.7 g/t silver, containing 57 billion pounds of copper, 71 million ounces of gold, 3.4 billion pounds of molybdenum and 345 million ounces of silver; and

The project is expected to process 43.8 million dry tonnes a year to produce 5.72 million ounces (Moz) of gold, 30.26Moz of silver, 3.58 billion pounds of copper, and 325 million pounds (Mlb) of molybdenum. It is anticipated to have a mine life of 22 years. CMC updated the project feasibility study (FS) for the Casino project in January 2013 ...

The Gajah Tidur copper-(molybdenum) and Main Grasberg copper-gold porphyry centers overlap in space and formed within ~250,000 years of one another. However, their distinct metal endowment, depth ...

A second magmatic-hydrothermal event resulted in a sericite- and pyrophyllite-rich advanced argillic overprint, which introduced more copper and gold to the system and recrystallized preexisting sulfides into both high and low sulfidation assemblages with high-fineness gold inclusions in pyrite and chalcopyrite and solid …

The value (-0.11 for gold, 0.84 for copper, 0.46 for molybdenum) reflects the trend at the time the chart was created, while the curves instead show the relationships between Western Copper and ...

In May 2021, Copper Fox filed an NI 43-101 Technical Report which included the results of an updated mineral resource for the Schaft Creek copper-molybdenum-gold silver porphyry project (click for report). To date the limits of the Schaft Creek deposit have not been defined and the area surrounding the deposit is considered to have excellent ...

Electrical conductivity in metals is a result of the movement of electrically charged particles. The atoms of metal elements are characterized by the presence of valence electrons, which are electrons in the outer shell of an atom that are free to move about. It is these "free electrons" that allow metals to conduct an electric current.

This publication contains the results of probabilistic estimates of the amounts of copper (Cu), molybdenum (Mo), gold (Au), and silver (Ag) in undiscovered porphyry …

NORTH AMERICA. In North America, FCX operates seven open-pit copper mines — Morenci, Bagdad, Safford, Sierrita and Miami in Arizona, and Chino and Tyrone in New Mexico; and two molybdenum mines — Henderson and Climax in Colorado. Molybdenum concentrate, gold and silver are also produced by certain of FCX's North America …

Nature Geoscience - Porphyry ore deposits supply much of the copper, molybdenum, gold and silver used by humans. A review of the main processes that …

The survey was designed to define potential porphyry copper-gold targets to a depth of 1,200 feet or more. Prior to the IP/Resistivity survey, a district-scale helicopter airborne magnetics radiometric survey was flown in September 2017 with 100-meter spaced N-S flight lines with 1000-meter tie lines flown E-W (see Figure 3).

When developed, we expect Michiquillay to produce 225,000 tons of copper per year (along with by-products of molybdenum, gold and silver) for an initial mine life of more than 25 years and at a competitive cash-cost. We estimate an investment of approximately $2.5 billion will be required and expect production start-up by 2032.
