Cambior (AMEX:CBJ)(TSE:CBJ.)

New Chief Financial Officer

Cambior Inc. announces the appointment of Bryan A. Coates, 43 years old, as Vice President, Finance and Chief Financial Officer.

Mr. Coates will be responsible for the management and administration of the finance, control, treasury, gold marketing and investor relations departments.

Prior to his appointment, Mr. Coates was Vice President, Finance and Administration at Compania Minera Antamina S.A. where he participated in the development of one of the world's largest base metals mine. He has more than 15 years experience in the mining industry, including 5 years with Cambior from 1991 to 1996.

Mr. Coates received an Honors Bachelor of Commerce degree from Laurentian University in Sudbury, Ontario and is a member of the Institute of Chartered Accountants of Ontario.

"Bryan will quickly be able to contribute to Cambior's management, due not only to his financial experience and expertise, but also because of his familiarity with the Company's assets and employees," said Louis P. Gignac, President and CEO of Cambior.

New Vice President Industrial Engineering and Environment

Cambior also announces the appointment of Serge Vezina, 58 years old, as Vice President, Industrial Engineering and Environment. Mr. Vezina joined the Company in 1988, and for the last several years has been responsible for improving and adapting the Company's environmental management system to bring it up to the ISO 14001 standard. Cambior is very proud to be the first and only North American gold mining company to be fully certified under this standard.

In the newly-created position, Mr. Vezina will first identify and study proven industrial techniques and methods at other mining and industrial companies, then train and coordinate personnel at the Company's operations in their use and application. The goal of this initiative is to improve productivity and efficiency, cut costs and enhance profitability. He will report to the President and CEO and will work closely with Messrs. Raynald Vezina, Senior Vice President, Canada, and Rejean Gourde, Senior Vice President, Guyana Shield. "Serge brings strong leadership and technical skills to his new position. His contributions at the senior management level will enhance our results," said Mr. Gignac.

"We have always aimed for continuous improvement in our operations, and we have made great strides, particularly in the past five years, in very difficult times for the metals markets. We are pleased with our progress, but we must strive to build on the achievements to date, as markets remain difficult and highly competitive. Our objective is to train our personnel and provide them with the tools and support they need to pursue their efforts systematically and with ongoing success," also noted Mr. Gignac.

Mr. Vezina's prior experiences include employment with QIT-Fer et Titane inc. in various progressive positions and with Laval University as Professor of Mining and Mineral Processing. He holds a Ph.D. in Metallurgy and a Bachelor's degree in Mining Engineering from Laval University. He is Chairman of the Board of COREM (a mineral research consortium) and is also involved in various technical, governmental and university committees. He is a member of the Quebec Order of Engineers and the Society of Mining Engineers of AIME, and is also a Fellow of the Canadian Institute of Mining and Metallurgy.
