Porphyry deposits are the most important ores of copper and molybdenum in western North and South America, and in other areas of the Pacific Rim. Most porphyry deposits also include some gold, and in a few cases gold is the primary commodity. A porphyry deposit forms around a cooling felsic stock (magma chamber) in the upper part of the crust.

Hydro thermal systems have been defined (Lindgren, 1922, 1933; Berger and Eimon, 1983) as epithermal systems if they formed within 1 km of the surface, at temperatures less than 300°C (mainly 150°-250°C), and from a fluid of meteoric origin, possibly with some magmatic input (White and Hedenquist, 1990; Simmons, 1995).

Collision and accretion of dozens of terranes for a 100-m.y.-long period against the western margin of North America and eastern margin of Eurasia led to widespread, latest Jurassic to Eocene gold veining in the northern Pacific basin.
This tendency is particularly contrasting along the northern Pacific Rim, in the North American Cordillera (e.g., Pogo, Fort Knox, and Dublin Gulch on the one hand and Caribou and Juneau on the other hand) and in Northeastern Asia (Chistoe, Malysh, Teutedzhak and Natalka, Nezhdaninskoe (Goryachev, 2003).

More than 420 million oz of gold were concentrated in circum-Pacific synorogenic quartz loades mainly during two periods of continental growth, one along the Gondwanan margin in the Palaeozoic and the other in the northern Pacific basin between 170 and 50 Ma.
This workshop demonstrates and describes ore deposit styles as well as exploration and conceptual exploration models as aids to the exploration and evaluation of southwest Pacific Rim magmatic arc mineral resources. However, careful consideration of the nature of these exploration models is necessary before any reliance can be placed upon them.
