CENTURY REPORTS 2004 FINANCIAL RESULTS

         MONTEREY, CA. Feb. 22, 2005 - Century Aluminum Company (NASDAQ:CENX)
today reported fourth quarter net income of $20.9 million, or $0.65 a common
share. The equipment failure at the St. Ann bauxite mine in Jamaica had an
estimated negative impact on fourth quarter net income of $2.2 million, or $0.07
a common share.

         The company reported a net loss of $6.3 million, or $0.32 a share after
preferred dividends for the fourth quarter of 2003. The 2003 quarter included
net after-tax charges of $6.3 million, or $0.30 a share, for mark-to-market
adjustments, the departure of an executive and an after-tax credit for lower of
cost or market inventory adjustments.

         Sales for the fourth quarter of 2004 were $290.6 million compared with
$205.8 million for the fourth quarter of 2003. Shipments of primary aluminum for
the 2004 fourth quarter were 346.7 million pounds, up over 20 percent from 286.9
million pounds shipped in the year-ago quarter.

         For all of 2004, Century reported net income of $28.0 million, or $0.95
a common share after preferred dividends. Total year results include a charge
for the early extinguishment of debt, $31.0 million after-tax, or $1.08 a common
share. In 2003, net income totaled $1.0 million with a loss of $0.05 a common
share after preferred dividends. Sales for 2004 were $1.06 billion compared with
$782.5 million for 2003, and total 2004 primary aluminum shipments of 1.32
billion pounds were up 17 percent from the 1.13 billion pounds shipped in 2003.

         Financial and operating results for 2004 include Nordural from the
April 27, 2004, acquisition date.

         "2004 was an outstanding year for Century Aluminum Company," said
chairman and chief executive officer Craig A. Davis. "We benefited from robust
aluminum prices. Primary aluminum production, shipments and sales were all-time
records. We completed the acquisition of the Nordural plant in Iceland and plan
to more than double its capacity to 212,000 metric tons per year (mtpy) by 2006.
In the strong markets that prevailed during the fourth quarter, we were able to
put in place a significant five-year forward sale. At the same time, a
substantial portion of our capacity remains unhedged, allowing us to participate
in the event of even stronger markets in the future. We also acquired an
interest in bauxite and alumina assets that will ensure supply to our
Hawesville, KY reduction plant."




         "We continued to improve our financial flexibility by strengthening our
balance sheet and significantly reducing our annual interest expense. For the
full year of 2004 we generated cash from operating activities of $105.8 million,
an increase of over 21 percent from 2003. Our operating income grew to $151.6
million, a five-fold increase from 2003."

         Century owns 615,000 mtpy of primary aluminum capacity. The company
owns and operates a 244,000 mtpy plant at Hawesville, KY, a 170,000 mtpy plant
at Ravenswood, WV and a 49.67-percent interest in a 222,000-mtpy reduction plant
at Mt. Holly, SC. Alcoa Inc. owns the remainder of the Mt. Holly plant and is
the operating partner. Century also owns a 90,000 mtpy plant at Grundartangi,
Iceland, and will expand that plant to 212,000 mtpy by 2006. After the
completion of the 122,000 mtpy Iceland expansion, Century will own 737,000 mtpy
of primary aluminum capacity. In addition, Century holds a 50 percent share of
the 1.25 million mtpy Gramercy Alumina Plant in Gramercy, LA. Century's
corporate offices are located in Monterey, CA.
