Cameco to provide toll processing services for Uranerz’s new uranium mine in Campbell County

Smith Ranch-Highland, November 30, 2011

Cheyenne, WY - Cameco Resources and Uranerz Energy Corporation have entered into an agreement by which material from Uranerz's recently licensed Nichols Ranch in situ uranium mine in Campbell County will be processed into uranium concentrate (yellowcake) at Cameco's central processing plant at the Smith Ranch-Highland Project in Converse County.

Smith Ranch-Highland is America's largest uranium operation and has the licensed capacity to mill four million pounds of uranium concentrate per year. Recent production has been just under two million pounds per year. Commercial in situ operations at the combined Smith Ranch-Highland Project began in 1988.

“Adding processing from Uranerz under a tolling agreement will help make both of our operations more efficient, ensuring jobs and continued growth in Wyoming's uranium industry,” said Cameco Resources' President Paul Goranson.

Uranerz is hiring additional personnel to work at its site during construction and operation, and announced it is focused on achieving commercial production as soon as practical.

“The addition of up to 800,000 pounds a year from Uranerz will still allow full growth from our own new sites that we are working to bring into production,” Goranson said.
