Freeport-Mcmoran Copper & Gold Inc. Announces Molybdenum
Financial Contacts: Media Contact: One North Central Avenue Phoenix, AZ 85004 Kathleen L. Quirk David P. Joint William L. Collier (602) 366-8016 (504) 582-4203 (504) 582-1750 Freeport-McMoRan Copper & Gold Inc. Announces Molybdenum Production Curtailment and Plans to Defer Restart of Climax Molybdenum Mine PHOENIX, AZ, November 10, 2008 – Freeport-McMoRan Copper & Gold Inc. (NYSE: FCX) announced today in response to the recent sharp decline in molybdenum prices plans to reduce production from its Henderson primary molybdenum mine and to defer the restart of the Climax molybdenum mine. Molybdenum markets have been strong in recent years, averaging $30 per pound in 2007 and $33 per pound in the nine months ended September 30, 2008. Slowing demand for molybdenum in the metallurgical and chemicals sectors during October 2008 combined with weak global economic conditions and turmoil in credit and financial markets has resulted in a sudden and sharp decline in molybdenum prices in recent weeks. The Metals Week Molybdenum Dealer Oxide price declined from approximately $30 per pound in mid-October 2008 to $12 per pound on November 10, 2008. In response to these conditions, FCX has revised its mine plans at its Henderson primary molybdenum mine near Empire, Colorado to operate at a reduced rate. This will result in a reduction in expected annual molybdenum production of approximately 10 million pounds, reflecting a 25 percent reduction in Henderson’s approximate annual production. FCX is also assessing the potential to curtail molybdenum production at its by-product mines. FCX also announced the suspension of construction activities associated with the restart of the Climax molybdenum mine near Leadville, Colorado. -

Vicki Seppala General Manager, Climax Mine Freeport-Mcmoran Inc
Vicki Seppala General Manager, Climax Mine Freeport-McMoRan Inc. 2019 Medal of Merit Recipient Non-traditional was a label used to describe Vicki Seppala when she returned to college. Returning to university after working in another industry was difficult but a path desired in her quest for a better life for herself and young son. It was just a Mine and Geological Engineering recruiting brochure on the science wall at Glendale Community College, but it caught her eye and Seppala soon found herself moving to Tucson with her fourth grade son and enrolling in the University of Arizona Geological Engineering program where she earned her Bachelor of Science Degree. She received scholastic scholarships each year and graduated with honors; she also was chosen the 1994 Outstanding Senior for the College of Engineering and Mines. After graduation, although the industry was in a down cycle, Seppala was hired as a Geological Engineer with the Phelps Dodge Sierrita mine (now Freeport-McMoRan Inc.). Her leadership skills and enthusiasm of new challenges propelled Seppala into operational roles of increasing responsibility rapidly rising to Mine Operations & Maintenance Superintendent. In 2003 she was promoted to Mine Technology Manager responsible for investigating, developing, and introducing new/existing technology to Freeport’s copper mines in North and South America. In 2006 Seppala was promoted to Mine Manager at Freeport’s Candelaria operation near Copiapo, Chile, becoming the first woman Mine Manager in Chile. The Mining Industry in Chile was rapidly changing with respect to women in nontraditional roles at that time, and Seppala became a part of that change.
