Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper . Deposits, prospects, and permissive tracts for porphyry and sediment-hosted copper resources worldwide, with estimates of undiscovered copper resources.

North America has a lot of mining knowledge and expertise when it comes to discovering and mining copper porphyry deposits. Here in British Columbia we have built a reputation for building quality copper-gold mines from enormous copper-gold and copper-molybdenum porphyries, such as Red Chris and Highland Valley. Jaguar habitats have also been harmed by burning their homeland in order to place buildings. El Jefes habitat is currently endangered due to Trump's border wall and the copper mine. Coyote. The Coyote (Canis latrans) is a canine that lives in North America, roaming the plains, deserts, mountains, and forests (Bradford, ).

Porphyry copper provinces are time-space clusters of porphyry copper deposits (PCDs) that form in magmatic arcs. The evolution of the Laramide arc of southwestern North America, which hosts the Laramide porphyry copper province—the second-largest in the world—provides insight into factors contributing to its transient and localized metallogenic fertility.
This volume, prepared as part of the Geological Society of America Annual Meeting in Phoenix, includes field guides covering aspects of the spectacular geology of southwestern North America.
Field guides tackle the geology of the southern Colorado Plateau, from paleoenvironments of Petrified Forest National Park, to Jurassic sand dunes of. works on porphyry copper deposits which have pre ceded it. Beginning in with Titley and Hicks' volume Geology of the Porphyry Copper Deposits, Southwestern North America, numerous anthologies have been dedicated to these deposits.
Such volumes have focused on deposits of the Canadian Cordillera. Porter, T.M. (ed.), - Super Porphyry Copper & Gold Deposits: A Global Perspective; PGC Publishing, Adelaide, v. 1, pages - ISBN This two volume set describes the great porphyry Cu-Au/Mo deposits and provinces around the globe and throughout geological time.

The use of the porphyry name became accepted and more widespread in the late s following the first dedicated book, Geology of the Porphyry Copper Deposits, Southwestern North America, in.
underlying porphyry systems and to predict the location of porphyry systems in districts that have dozens of breccia pipes. The Sombrero Butte breccia pipe system is located at the southern end of the Copper Creek (Bunker Hill) mining district in the Laramide porphyry copper province of southwestern North America (Titley, ).
The Chuquicamata porphyry copper deposit (22°′S, 68°54′W; – m-a.s.l.) in northern Chile and the other giant porphyry deposits of the Central Andes orogen were formed along a non-collisional convergent margin above a long-lived, currently-active subduction ore deposits have a direct genetic link to magmatic activity associated with subduction (Clark and Zentilli.
The Caspiche porphyry gold-copper deposit, part of the Maricunga gold-silver-copper belt of northern Chile, was discovered in beneath postmineral cover by the third company to explore the. Sulphide and flotation concentrates from 33 porphyry copper deposits have been investigated for platinum-group elements (PGE), Au, Cu and platinum-group minerals (PGM).
The major sulphides in the samples studied are chalcopyrite and pyrite. Bornite is less frequent and molybdenite occurs in traces only. PGM (merenskyite, sperrylite and an unidentified Pd-Sb telluride) have been found as.
13 equal horizontal stripes of red (top and bottom) alternating with white; there is a blue rectangle in the upper hoist-side corner bearing 50 small, white, five-pointed stars arranged in nine offset horizontal rows of six stars (top and bottom) alternating with rows of five stars; the 50 stars represent the 50 states, the 13 stripes represent the 13 original colonies; blue stands for loyalty.

Robinson is considered by the USGS to be one of the?Giant Porphyry-Related Metal Camps of the World. Bywhen the large porphyry copper mines closed, the Robinson mine area deposits had produced nearly million tons of 1% copper ore, which included million ounces of byproduct gold.

New soil geochemistry and airborne magnetic data from Impact Minerals Limited's (ASX:IPT) Apsley Prospect within its % owned Commonwealth project in the Lachlan copper-gold province of New South Wales (Figure 1) have defined almost text book examples of the zonation expected around a large porphyry copper-gold deposit with three priority areas defined for follow up work.
North America hosts highly mineralized porphyry copper tracts that include supergiant (>25 million tons copper) porphyry deposits in northern Mexico, the western United States, and Alaska, as well as giant deposits in western Canada.
The estimated undiscovered porphyry copper resources are approximately equal to the identified resources. Description: There were 4 characteristics used in making the Chalcophanite identification. First is the tetragonal crystal habit, second is the elongated, columnar habit when you view any of the broken crystalized areas from the side, color is another, when seen as individual tiny, free standing crystals they are jet black and the last is the hardness, they are about on the mohs scale.
Porphyry Copper Spence was a world authority on porphyry copper systems, metal provinces and metallogenesis. The books he wrote and edited and the scholarly articles he published on porphyry copper deposits of southwestern North America have been read by.
