              CENTURY ALUMINUM REPORTS SECOND QUARTER 2005 EARNINGS

MONTEREY, CA. July 27, 2005 -- Century Aluminum Company (NASDAQ:CENX) reported
net income of $40.7 million, or $1.27 a share, fully diluted, for the second
quarter of 2005. Reported after-tax net income was positively impacted by the
following items:

   -  $15.7 million or $0.49 a share, for mark to market adjustments on forward
      contracts that do not qualify for cash flow hedge accounting.

   -  The Company has recorded income taxes on Nordural earnings assuming that
      they will be subject to United States income taxes from the date of
      acquisition, April 27, 2004 to March 31, 2005. During the second quarter
      of 2005, management determined that certain Nordural earnings would remain
      invested overseas indefinitely to fund growth opportunities in Iceland and
      elsewhere. Accordingly, United States income taxes are no longer provided
      on such earnings.

In the second quarter of 2005, the Company changed from the last-in first-out
(LIFO) inventory valuation method to the first-in first-out (FIFO) method.
Management believes that the change will provide a better matching of costs and
revenues. The change did not have a material impact on net income in the second
quarter. Financial statements for periods prior to second quarter 2005 have been
restated to reflect this change.

For the second quarter of 2004, the Company reported net income of $19.2
million, or $0.63 a share, fully diluted ($18.3 million, or $0.60 a share, fully
diluted, before restatement).

Sales in the second quarter of 2005 were $283.3 million compared with $263.7
million in the second quarter of 2004. Shipments of primary aluminum for the
quarter totaled 339.5 million pounds compared with 330.4 million pounds in the
year-ago quarter.

Net income for the first six months of 2005 was $52.5 million, or $1.63 a share,
fully diluted ($51.9 million, or $1.61 a share before restatement). This
compares with net income of $24.8 million, or $0.94 a share, fully diluted in
the year-ago period ($23.1 million, or $0.87 a share, fully diluted before
restatement).

Sales in the first six months of 2005 were $568.7 million compared with $495.8
million in the same period of 2004. Shipments of primary aluminum for the 2005
period were 676.5 million pounds compared with 627.2 million pounds in the
year-ago period.

Financial results and shipment data for 2004 include Nordural from April 27,
2004, the date of acquisition.

"Although aluminum prices were off somewhat from the first quarter, we continued
to benefit from a favorable market," said Craig Davis, chairman and chief
executive officer. "All of our facilities exceeded expectations except for
Hawesville, which continued to experience operational difficulties, including a
higher than average level of pot failures. The strong forward market that
prevailed in the quarter allowed us to put in place a significant eight-year
forward sale, beginning in 2008. As is our practice, however, a substantial
portion of our capacity remains unhedged, which allows us to participate in the
event of even stronger future markets."

Century presently owns 615,000 metric tonnes per year (mtpy) of primary aluminum
capacity. The company owns and operates a 244,000 mtpy plant at Hawesville,
Kentucky; a 170,000 mtpy plant at Ravenswood, West Virginia; and a 90,000 mtpy
plant at Grundartangi, Iceland that is being expanded to 212,000 mtpy. The
company also owns a 49.67-percent interest in a 222,000 mtpy reduction plant at
Mt. Holly, South Carolina. Alcoa Inc. owns the remainder of the plant and is the
operating partner. With the completion of the Grundartangi expansion, Century's
total capacity will stand at 737,000 mtpy. Century also holds a 50-percent share
of the 1.25 million mtpy Gramercy Alumina refinery in Gramercy, Louisiana and
related bauxite assets in Jamaica. Century's corporate offices are located in
Monterey, California.

  1)The forward priced sales in 2005 exclude July 2005 shipments to customers
    that are priced based upon the prior month's market price.

  2)Certain financial sales contracts included in the forward priced sales base
    volume for the period 2006 through 2015 contain clauses that trigger
    potential additional sales volume when the market price for a contract month
    is above the base contract ceiling price. These contracts will be settled
    monthly and, if the market price exceeds the ceiling price for all contract
    months through 2015, the potential additional sales volume would be
    equivalent to the amounts shown above.
