Cambior Calls for Rejection of Aur Offer.

Business Editors

MONTREAL--(BUSINESS WIRE)--Feb. 9, 2000

(TSE:CBJ.) (AMEX:CBJ)

In connection with the offer (the &uot;Offer&uot;) dated January 24, 2000 by Aur Resources Inc. (&uot;Aur&uot;) to acquire all outstanding Common Shares of Cambior Inc. (&uot;Cambior&uot;), Cambior's Board of Directors recommended in a Supplemental Circular dated today that Cambior Shareholders REJECT the Offer, subject to any further communication from the Board.

The Board of Directors of Cambior has received an opinion from Bunting Warburg Dillon Read Inc., its financial advisors, stating that the consideration under the Offer is INADEQUATE from a financial point of view to Cambior Shareholders. A copy of the opinion is included with the Supplemental Circular.

The Board continues to view the Offer as deficient in several other material respects noting, among other things, that:

* The Offer is highly conditional;

* There is a potential immediate acceleration of Cambior's
  obligations to its financial creditors upon a change of control
  of Cambior;

* The Offer is coercive because it is open only for a period that
  falls well short of the 60-day period contemplated for a Permitted
  Bid under Cambior's Shareholder Protection Rights Plan;

* The Offer seeks to pre-empt and truncate Cambior's value
  maximization process which contemplates divestitures of particular
  assets to purchasers likely to pay the maximum price for such
  assets;

* The timing of the Offer is opportunistic having regard to the
  depressed condition of the market for gold and shares of gold
  producers;

* The effective premium under the Offer is significantly reduced by
  the dilutive effect of the Offer;

* The Offer fails to unlock or fully recognize the value of
  Cambior's assets; and

* Other offers or alternatives may emerge.

Cambior will mail the Supplemental Directors' Circular in response to the Offer today to all of its shareholders. The Supplemental Circular will also become available today on Cambior's web site &uot;www.cambior.com.&uot; Shareholders are urged to read the Supplemental Directors' Circular and the opinion of Bunting Warburg Dillon Read Inc. in their entirety.

The Board continues to explore, with the advice and assistance of Cambior's financial and legal advisors, various alternatives in order to maximize shareholder value. These alternatives include a competing bid for all of the Common Shares of Cambior, a sale of Cambior's gold division or individual gold assets, and a sale of all or some of Cambior's non-gold assets. Although there can be no assurance, Cambior believes that a financially superior alternative to the Offer may emerge from the process currently under way. The Board also intends to engage Aur in discussions concerning the Offer.
