Cambior Responds to Unsolicited Tender Offer.

MONTREAL--(BUSINESS WIRE)--June 4, 1999--

CAMBIOR (ME:CBJ.) (TSE:CBJ.) (AMEX:CBJ) Cambior Inc. ("Cambior") has become aware that an entity calling itself "Bezira Gold Inc." has circulated an offer to purchase up to 1.0 percent of the outstanding common shares of Cambior at a price of U.S. $2.75 per share.

Cambior strongly recommends that shareholders NOT tender their shares into this offer. Cambior's common shares trade actively on the Montreal Exchange, The Toronto Stock Exchange and the American Stock Exchange. The price offered by Bezira falls well below the current bid price for Cambior shares on each of the above-mentioned exchanges. Indeed, Cambior shares have never traded at a price as low as U.S. $2.75 per share in the Company's 13 year history.

Cambior has no knowledge of Bezira Gold and has had no communications with any person purporting to represent Bezira Gold. However, the offer appears to follow a pattern recently observed in relation to various other companies. In each case the companies appear to be targeted by bids for a relatively low volume of shares at a price substantially below the published market price for such shares on recognized stock exchanges. As an example, we refer to an article appearing on page B-1 of the May 31, 1999 edition of the Globe and Mail entitled "Mini-tenders invade Canada".

Investors requiring further information regarding current and recent price ranges and trading volumes for Cambior's shares should contact their investment advisors or brokers or Cambior's Investor Relations department at the numbers indicated below.

Cambior Inc. is an international diversified gold producer with operations, development projects and exploration activities throughout the Americas. Cambior is the first gold mining company to receive ISO 14001 certification of its environmental management system. Cambior's shares trade on the Toronto, Montreal and American (AMEX) stock exchanges under the symbol "CBJ".
