BLIND RIVER, Ontario--(BUSINESS WIRE)--March 13, 2002

Cameco Corporation's (NYSE:CCJ)(TSE:CCO) Blind River uranium refinery officially received today, during a ceremony at the plant, certification under the ISO 14001 program, one of the most internationally recognized standards for environmental management systems.

"This achievement is the result of several years of planning and preparation by our employees," said Bob Steane, Cameco's vice-president of fuel services. "It demonstrates how seriously we take environmental responsibilities and our ongoing commitment to the community of Blind River."

"We are very proud of our accomplishment here at Blind River and are pleased to showcase our commitment to the environment through this international recognition" said Catherine Green, manager of the Blind River refinery.

ISO 14001 is an international standard through which a company can demonstrate its commitment to sound environmental performance in compliance, pollution prevention and continual improvement. It establishes a permanent framework to assist companies in reaching their environmental protection goals. This framework calls for annual independent audits and for re-certification every three years. The International Organization for Standardization issued ISO 14001 in 1996.

The Blind River operation received certification following an audit conducted by the Quality Management Institute (QMI) of Mississauga, Ontario, a division of CSA International.

"Most of the components of an environmental management system have been in place at all our operations, including Blind River, for some time," said Bernard Michel, Cameco's chair and chief executive officer. "We have decided to introduce and implement a more formal system, based on ISO 14001, to ensure greater consistency across the company and to foster among our employees an attitude of continual search for improvement in our environmental protection performance." Cameco received ISO 14001 certification for the Port Hope conversion facility in 2000 and will seek certification at the McArthur River and Key Lake operations later this year.

Cameco, with its head office in Saskatoon, Saskatchewan, is the world's largest uranium supplier. The company's uranium products are used to generate electricity in nuclear energy plants around the world, providing one of the cleanest sources of energy available today. Cameco's shares trade on the Toronto and New York stock exchanges.
