Robinson Mine. The Robinson Mine is a porphyry copper deposit located at Ruth, White Pine County, Nevada, in the Egan Range, 4 miles (6.4 km) west of Ely. The mine comprises three large open pits: Liberty, Tripp-Veteran and Ruth. The ore is extracted using conventional surface methods, and is then processed into a copper-gold concentrate, and a ...
Porphyry copper deposits represent an important resource and the dominant source of copper that is mined today to satisfy global demand. [6] Via compilation of geological data, it has been found that the majority of porphyry deposits are Phanerozoic in age and were emplaced at depths of approximately 1 to 6 kilometres with vertical thicknesses on average of 2 kilometres.

The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [ 1 ] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals.
Classification. Iron oxide copper gold (IOCG) deposits are considered to be metasomatic expressions of large crustal-scale alteration events driven by intrusive activity. The deposit type was first recognised by discovery and study of the supergiant Olympic Dam copper-gold-uranium deposit (Olympic Dam mine), and South American examples.
Peak copper is the point in time at which the maximum global copper production rate is reached. Since copper is a finite resource, at some point in the future new production from mining will diminish, and at some earlier time production will reach a maximum. When this will occur is a matter of dispute.
Mirador mine. 137 Million lbs of copper; 34,000 oz gold; and 394,000 oz silver per year. [2] The Mirador mine is a large copper mine located in the Amazonian province of Zamora-Chinchipe in southern Ecuador. It is one of the largest copper reserves in Ecuador, [1] and the first industrial-scale copper project to be developed in the country.
Mineral Park was a mining town, now a ghost town in the Mineral Park valley of the Cerbat Mountains in Mohave County, Arizona. [6] Its ruins and cemetery are now located within the property of the mine. [7] Mining in the area began in 1871 and a camp was established soon after. The mines produced primarily silver, gold, copper, lead and zinc.
