Porphyry copper deposits are generally composed of a "plug-like" igneous intrusion– a large magma body that is emplaced beneath a volcanic system. On average these deposits can have a vertical and horizontal extent of 1-2 km and can range from tens of millions to more than one billion tons in size. While coppe…See more on geologyforinvestors
WEBEconomic analysis of 143 major deposits found between 1985-2003 showed that much of the industry's wealth is captured in a handful of discoveries. For gold: Of those >0.5 mt …
1. What are the types of copper deposits? Porphyry copper deposits are low grade, but are important sources of copper because they can be worked at a large scale for low costs. They typically...
Copper (Cu) ore is a naturally occurring mineral deposit that contains copper in varying concentrations. It is an important industrial metal that has been used by human civilizations for thousands of years due to its excellent electrical and thermal conductivity, high ductility, and resistance to corrosion. Copper is widely used in various …
The world-class San Rafael tin (-copper) deposit (central Andean tin belt, southeast Peru) is an exceptionally large and rich (>1 million metric tons Sn; grades typically >2% Sn) cassiterite-bearing hydrothermal vein system hosted by a late Oligocene (ca. 24 Ma) peraluminous K-feldspar-megacrystic granitic complex and surrounding Ordovician …
The scale at which a particular deposit becomes world class depends on the metal. For example, Singer describes a world-class gold deposit as containing at least 3.2 million ounces of the yellow metal. In contrast, he believe world-class copper deposits should host at least 2 million metric tons of the base metal.

About 75 percent of the world's copper comes from porphyry copper deposits. That's three-quarters of the copper in your phone, your laptop and other high-tech devices that use the metal in their circuits. New research at the University of Idaho and the University of Michigan unearths how porphyry copper deposits are distributed around the ...
World-class Copper Deposits Copper occurs in many forms, and in a variety of geological settings. Here's what makes a world-class copper deposit....
What makes a world-class copper deposit? While there are other factors to consider when valuing a copper deposit, the upshot is that a world-class copper deposit holds a copper resource whose ...
Tonnage of mineralized rock is an even better predictor of contained metal with over 96 percent of each metal's total residing in deposits having greater than median size and between 47 and 79 percent of metal contained in the largest 10 percent of deposits. World class deposits, defined as the upper 10 percent of deposits in terms of contained ...
Geological Requirements. There are four requirements necessary to form an oil deposit: 1) there must be a source rock, 2) there must be a heating event, 3) there must be a reservoir rock, and 4 ...
While there are other factors to consider when valuing a copper deposit, the upshot is that a world-class copper deposit holds a copper resource whose value far exceeds the cost of mining and ...
Detailed studies of the host lithologies, mineral textures, metal zoning and configurations of numerous sediment‐hosted stratiform copper deposits have established a post‐sedimentary (diagenetic) timing and overprint concept for the genesis of this important mineral deposit type. Metals were probably deposited from low‐temperature oxidised …
World class deposits, defined as the upper 10 percent of deposits in terms of contained metal, account for over 86 percent of all gold, 79 percent of silver, 84 …
Copper deposits derived from porphyry magmas are the largest sources of copper and molybdenum, and are a significant source of gold to world markets 1.
According to research in the area, key factors that led to the development of the world-class Antamina deposit include: (i) mantle-derived intrusions; (ii) favourable …
The Alpala porphyry copper-gold deposit is a recent discovery in northern Ecuador (Figure 1). The deposit lies within the Cascabel Project which is about 100 km north of Quito, the capital of Ecuador, and 50 km north-northwest of Ibarra in Imbabura Province. The project is located about 20 km south of the border with Colombia and 130 km east of the Pacific …
The deposits that contain the largest quantities of copper are called porphyry deposits, and the process of extracting it usually involves drilling an open pit into a …
