Cameco Acquires Interest in Uranium Exploration Company

Saskatoon, Saskatchewan, Canada, June 19, 2006 . . . . . . . . . . . . . . .

Cameco Corporation announced today that it has acquired a 19.5% share of UNOR Inc. and signed a strategic alliance with the company.

UNOR (formerly Hornby Bay Exploration Ltd.) is a uranium exploration and development company with its head office in Toronto, Ontario. Its principal properties are 226 mineral claims in northwestern Nunavut on the Hornby Basin, a geological formation with similar characteristics to the uranium-rich Athabasca Basin in northern Saskatchewan. UNOR’s shares trade on the TSX Venture Exchange.

Cameco purchased 22.9 million common shares of UNOR at $0.40 per share through a private placement for $9.2 million. The strategic alliance agreement concluded between Cameco and UNOR includes the following terms:

•		As long as Cameco continues to hold 10% of UNOR’s outstanding common shares, it will have the right to nominate one person for election to UNOR’s board of directors, and UNOR will consult with Cameco on its exploration and development programs;
•		As long as Cameco continues to hold 16% of UNOR’s outstanding common shares, it will have the right to participate in any future equity issues, match equity or debt required for mine development, operate any mine developed on UNOR’s properties and market any uranium produced; and
•		Cameco and UNOR each have right of first refusal on each other’s uranium projects in a specified area of Nunavut and the Northwest Territories.

“This agreement strengthens our effort to identify new uranium reserves for the future,” said Cameco president and CEO Jerry Grandey. “Cameco gains the right to participate in the exploration of new regions and adds the expertise of a solid technical team to our knowledge base.”

Cameco, with its head office in Saskatoon, Saskatchewan, is the world’s largest uranium producer. 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.
