Exhibit 10.1

EXECUTION COPY

CONSENT AND SECOND AMENDMENT TO
REVOLVING CREDIT AGREEMENT

        This CONSENT AND SECOND AMENDMENT TO REVOLVING CREDIT AGREEMENT, dated
as of March 31, 2004 (this “Amendment”), is by and among (a) Century Aluminum
Company, a Delaware corporation (“Century Aluminum”), Berkeley Aluminum, Inc., a
Delaware corporation (“Berkeley”), Century Aluminum of West Virginia, Inc., a
Delaware corporation (“Century WV”), Century Kentucky, Inc., a Delaware
corporation (“Century K”), Metalsco, Ltd., a Georgia company (“Metalsco”) and
NSA Ltd., a Kentucky limited partnership (“NSA” and, together with Century
Aluminum, Berkeley, Century WV, Century K and Metalsco, collectively, the
“Borrowers” and each individually a “Borrower”), (b) the lending institutions
which are or may become parties to the Credit Agreement (as defined below) from
time to time (collectively, the “Lenders”) and (c) Fleet Capital Corporation as
agent (“Agent”) for the Lenders. Capitalized terms used herein without
definition shall have the meanings assigned to such terms in the Credit
Agreement referred to below.

        WHEREAS, the Borrowers, the Lenders and the Agent are parties to a
Revolving Credit Agreement, dated as of April 2, 2001 (as amended, restated,
supplemented or otherwise modified and in effect from time to time, the “Credit
Agreement”), pursuant to which the Lenders have committed to make loans or
otherwise extend credit to the Borrowers on the terms and subject to the
conditions set forth therein;

        WHEREAS, Century Aluminum has entered into that certain Stock Purchase
Agreement by and among Century Aluminum, as Buyer, Columbia Ventures
Corporation, a Washington corporation, as Seller, and Nordural (as hereinafter
defined), which Stock Purchase Agreement will be amended and restated
substantially in the form attached hereto as Exhibit A (as amended and restated,
the “Stock Purchase Agreement”), pursuant to which Century Aluminum shall cause
the Nordural Acquisition Subsidiary (as hereinafter defined) to consummate the
Nordural Acquisition (as hereinafter defined).

        WHEREAS, Century Aluminum intends to issue shares of its Common Stock,
par value $.01 per share, in a public offering (the “Offering”), with estimated
net proceeds of up to $285 million (the “Net Offering Proceeds”).

        WHEREAS, Century Aluminum intends to contribute or lend all or a portion
of the Net Offering Proceeds to the Nordural Acquisition Subsidiary to fund the
Nordural Acquisition, to finance a portion of a planned expansion by Nordural
and to provide working capital to Nordural (the “Nordural Investment”). Under
the Credit Agreement, (i) the Nordural Investment is not permitted and (ii) the
Nordural Acquisition Subsidiary is not permitted to consummate the Nordural
Acquisition because it is a Subsidiary of Century Aluminum.

        WHEREAS, in accordance with the terms hereof, the Lenders and the Agent
have agreed to consent to the Nordural Investment and specify that the Nordural
Acquisition Subsidiary is not a Subsidiary of the Borrowers or the Guarantors.

--------------------------------------------------------------------------------

        NOW THEREFORE, in consideration of the foregoing premises and for other
good and valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the Borrowers, the Lenders and the Agent hereby agree as follows:

        §1.  Amendment to Section 1.1 of the Credit Apreement.

          (a) Section 1.1 of the Credit Agreement is hereby amended by adding
the following new definitions to such Section 1.1 in the appropriate
alphabetical order:

          “Nordural.” Nordural hf, an Icelandic company that owns and operates a
primary aluminum plant in Grundartangi, Iceland.

          “Nordural Acquisition.” The purchase on one occasion by the Nordural
Acquisition Subsidiary of 100% of the outstanding shares of capital stock of
Nordural pursuant to the terms of the Stock Purchase Agreement.

          “Nordural Acquisition Documents.” All agreements, documents and
instruments executed and/or delivered in connection with the Nordural
Acquisition (other than the Stock Purchase Agreement), in form and substance
consistent with the Stock Purchase Agreement.

          “Nordural Acquisition Subsidiary.” One or more direct or indirect
subsidiaries of Century Aluminum (which are not Borrowers or Guarantors) formed
for the purpose of, and used to consummate, the Nordural Acquisition or which
are used from time to time to hold direct or indirect ownership interests in
Nordural.

          (b) The definition of “Subsidiary” is hereby amended by deleting such
definition in its entirety and substituting the following definition in lieu
thereof:

          “Subsidiary. Any corporation, association, trust, or other business
entity of which the designated parent shall at any time own directly or
indirectly through a Subsidiary or Subsidiaries at least a majority (by number
of votes) of the outstanding Voting Stock; provided, however, that when used
with respect to the Borrowers and the Guarantors, the term Subsidiary shall not
include the European Subsidiary or the Nordural Acquisition Subsidiary.”

        §2.  Consent to the Nordural Investment. The Borrowers have requested
that the Agent and the Lenders consent to the Nordural Investment.
Notwithstanding the provisions of Section 9.3 of the Credit Agreement which
might limit or prohibit the Borrowers’ ability to make the Nordural Investment,
the Agent and the Lenders hereby consent to the Nordural Investment in
connection with the Nordural Acquisition provided that (a) the amount of the
Nordural Investment shall not exceed the amount of the Net Offering Proceeds,
(b) no Letters of Credit are issued in connection with the Nordural Acquisition
and (c) for the three (3) days immediately following the closing of the Nordural
Acquisition, no Loans are outstanding.

-2-

--------------------------------------------------------------------------------

        §3.  Application of Section 10.1 of the Credit Apreement. For the
avoidance of doubt, the Agent and the Lenders confirm and agree that the
Nordural Investment will not be considered to be a Capital Expenditure which
would otherwise be restricted under the terms of Section 10.1 of the Credit
Agreement.

        §4.  Conditions to Effectiveness. This Amendment shall become effective
upon the satisfaction of each of the following conditions precedent; provided
that if the Stock Purchase Agreement is terminated by Buyer or Seller (as
defined therein) pursuant to Article XI thereof, this Amendment shall be null

Amendment duly executed and delivered by each of the Borrowers and the Majority

          (b) the Agent shall have received an executed copy of the Stock
Purchase Agreement which shall be substantially in accord with the draft Stock
Purchase Agreement attached hereto as Exhibit A with such material deviations or
changes as are otherwise satisfactory to the Agent;

          (c) the Agent shall have received evidence reasonably satisfactory to
the Agent that the Offering has been consummated; and

          (d) the Agent shall have received payment from the Borrowers, for the
account of each Lender which returns an executed counterpart signature page to
this Amendment to the Agent on or prior to 5:00pm (Chicago time) on March 31,
2004, of an amendment fee equal to $5,000 for each such Lender.

        §5.  Affirmation of the Borrowers. Each of the Borrowers hereby affirms
all of its Obligations under the Credit Agreement and under each of the other

Documents.

        §6.  Representations and Warranties. Each of the Borrowers hereby
represents and warrants to the Lenders and the Agent as follows:

          (a) Representations and Warranties. Each of the representations and
warranties contained in Section 7 of the Credit Agreement were true and correct
in all material respects when made, and, after giving effect to this amendment,
are true and correct in all material respects on and as of the date hereof,
except to the extent of changes resulting from transactions contemplated or
permitted by the Credit Agreement (as amended hereby) and the other Loan
Documents, changes occurring in the ordinary course of business that singly or
in the aggregate do not result in a Material Adverse Effect and to the extent
that such representations and warranties relate specifically to a prior date.

          (b) Enforceability. The execution and delivery by each of the
Borrowers of this Amendment, and the performance by each of the Borrowers of
this Amendment and the Credit Agreement, as amended hereby, are within the
corporate authority of such Borrower and have been duly authorized by all
necessary corporate proceedings. This Amendment and the Credit Agreement, as
amended hereby, constitute valid and legally binding obligations of each of the
Borrowers, enforceable against it in accordance with their terms, except as
limited by bankruptcy, insolvency, reorganization, moratorium or similar laws
relating to or affecting the enforcement of creditors’ rights in general.

-3-

--------------------------------------------------------------------------------

          (c) No Default. No Default or Event of Default has occurred and is
continuing, and no Default or Event of Default will result from the execution,
delivery and performance by each of the Borrowers of this Amendment or from the
consummation of the transactions contemplated herein.

        §7.  No Amendments, etc. Except as expressly provided in this Amendment,
(a) all of the terms and conditions of the Credit Agreement and the other Loan
Documents remain unchanged, and (b) all of the terms and conditions of the
Credit Agreement, as amended hereby, are hereby ratified and confirmed by each

construed to be an amendment, consent or a waiver of any requirements of any of

other Loan Documents except as expressly set forth herein. Nothing in this
Amendment shall be construed to imply any willingness on the part of the Agent
or the Lenders to grant any similar or future amendment, consent or waiver of
any of the terms and conditions of the Credit Agreement or the other Loan
Documents.

        §8.  Execution in Counterparts. This Amendment may be executed in any
number of counterparts and by each party on a separate counterpart, each of
which when so executed and delivered shall be an original, but all of which
together shall constitute one instrument. In proving this Amendment, it shall
not be necessary to produce or account for more than one such counterpart signed
by the party against whom enforcement is sought.

        §9.  Governing Law. This Amendment shall for all purposes be construed
in accordance with and governed by the laws of the State of New York (excluding
the laws applicable to conflict of laws, other than Section 5-1401 of the New
York General Obligations Law).

        §10.  Miscellaneous. The captions in this Amendment are for convenience
of reference only and shall not define or limit the provisions hereof.

        §11.  Fees and Expenses. Each of the Borrowers agrees to pay to the
Agent, on demand by the Agent, all reasonable out-of-pocket costs and expenses
incurred or sustained by the Agent in connection with the preparation of this
