HIDDEN MINERAL DEPOSITS IN Cu-DOMINATED PORPHYRY
Aug 01, 2013The Ok Tedi Cu-Au-Ag deposit of western Papua New Guinea also is generally thought of as a major porphyry Cu deposit, yet hosts both porphyry and skarn mineralization. Current reserve estimates indicate that the majority of the contained metal within the deposit is hosted by skarns rather than porphyry bodies.

Resources and Reserves CliffsNotes
A resource is that amount of a geologic commodity that exists in both discovered and undiscovered deposits—by definition, then, a “best guess.”. Reserves are that subgroup of a resource that have been discovered, have a known size, and can be extracted at a profit. For example, of the world's estimated oil resource of three trillion

Porphyry Deposits: The World’s Largest Source of Copper
May 28, 2014These deposits provide over 60% of the world’s copper and include other important metals such as molybdenum, gold and silver. Porphyry copper deposits are known for their low grades and very high tonnage. A porphyry is not a rock type, but rock with a particular texture. This porphyritic rock has large feldspar crystals in a finer grained matrix.
