From its discovery in 1968 to its legacy as North America’s longest-operating uranium facility, Cameco's Rabbit Lake’s story is one of resilience, teamwork and a few legendary safety awards along the way. Rabbit Lake uranium deposit was discovered in 1968. The site began production in 1975. “Fifty years is a remarkable milestone, and it’s all thanks to the many people who have made Rabbit Lake what it is,” said CEO Tim Gitzel. “Your dedication, innovation and teamwork have not only powered our operations, but have helped set the standard for safety and community spirit at Cameco."
