Freeport-McMoRan Copper & Gold Inc.
Freeport-McMoRan Copper & Gold (FCX) really digs its profits. Its 91%-owned subsidiary, PT Freeport Indonesia (PT-FI), operates the vast open-pit Grasberg gold, copper, and silver mine in Indonesia, whose government owns the other 9%. FCX controls proved and probable reserves of about 100 billion pounds of copper, 47 million ounces of gold, and 2.5 billion pounds of molybdenum. Copper, in the form of concentrates and in refined products such as cathodes and anodes, accounts for most of FCX's sales. It's the world's #2 copper company behind Codelco. FCX is also engaged in smelting and refining through PT-FI's 25% stake in PT Smelting, which operates a copper smelter and refinery in Indonesia.
