FCX has signicant reserves, resources and future development opportunities within its
portfolio of assets. FCXs estimated consolidated recoverable proven and probable reserves as
of December 31, 2011, include 119.7 billion pounds of copper, 33.9 million ounces of gold,
3.42 billion pounds of molybdenum and 0.86 billion pounds of cobalt. ese estimates of
recoverable proven and probable reserves were determined using long-term average prices
of $2.00 per pound for copper, $750 per ounce for gold, $10 per pound for molybdenum and
$10 per pound for cobalt.
FCX’s operating mines and other properties also contain mineralized material that it believes
could be brought into production should market conditions warrant. As of December 31, 2011,
FCX identied estimated mineralized material totaling 115 billion pounds of incremental
contained copper, which was assessed using a long-term average copper price of $2.20 per pound.
FCX continues to aggressively pursue opportunities to convert this mineralized material into
reserves, future production and cash ow.
