Cambior Inc.: Temporary Reduction of Production at Omai Bauxite Mine in Guyana

LONGUEUIL, QUEBEC--(CCNMatthews - June 5, 2006) - Omai Bauxite Mining Inc. ("OBMI"), a subsidiary of Cambior Inc., has advised the Government of Guyana that it will temporarily suspend part of its operations on July 1, 2006, for two months, thereby reducing its workforce by approximately 350 employees. The suspension results from lower demand for its Refractory "A" Grade Super Calcined Bauxite ("RASC") during the summer months, and will allow OBMI to reduce its RASC inventories.

Although significantly reduced, Omai Bauxite Mine operations will be maintained as the production of chemical grade bauxite will be increased to minimize the impact. Fixed costs for the 2-month RASC production shutdown are estimated at $1 million.

Cambior Inc. is an international gold producer with operations, development projects and exploration activities throughout the Americas. Cambior's shares trade on the Toronto (TSX) and American (AMEX) stock exchanges under the symbol "CBJ". Cambior's warrants "CBJ.WT.C" and "CBJ.WT.D" trade on the TSX.
