Century Issues Conditional WARN Notice and Announces the Curtailment of One Potline at Ravenswood, WV Smelter

MONTEREY, CA--(Marketwire - December 17, 2008) - Century Aluminum of West
Virginia, a wholly owned subsidiary of Century Aluminum Company (NASDAQ: CENX),
today informed employees at its Ravenswood, WV aluminum smelter of a possible
curtailment of 100% of plant operations in 60 days. The announcement was made
pursuant to the federal Worker Adjustment and Retraining Notification Act
(WARN). In a related move, the company also began the orderly curtailment of
one potline. 

The conditional WARN notice specifies that the plant could be curtailed unless
the LME selling price for aluminum stabilizes and the company is able to
materially reduce costs and stem monthly losses. Century Aluminum of West
Virginia will be actively seeking cost reductions in power, alumina, coke,
pitch, labor and other materials and services. If the LME price for aluminum
does not stabilize and/or the company is unable to obtain the necessary monthly
cost savings, the company will curtail 100% of smelter operations, beginning
February 15, 2009. 

The orderly curtailment of one potline will begin immediately and will be
completed by December 20. The action will reduce plant primary aluminum
production by approximately 3,540 tonnes per month. The potline curtailment
will ultimately impact an estimated 100 hourly and 20 salaried employees, who
will be temporarily redeployed throughout the Smelter on December 20 after the
curtailment is completed. 

"These are economic decisions based on the global economic crisis and the
unprecedented decline in aluminum prices," said Ravenswood plant manager Jim
Chapman. "We are experiencing significant losses at the current aluminum price.
The potline curtailment will allow us to immediately reduce our cash losses
while we work diligently over the next 60 days with suppliers, customers,
employees and government officials to explore all avenues for improving plant
economics and maintaining operations." 

Century Aluminum Company, the parent of Century Aluminum of West Virginia, owns
primary aluminum capacity in the United States and Iceland, as well as an
interest in alumina and bauxite assets in the United States and Jamaica.
Century's corporate offices are located in Monterey, California.
