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…
