Cameco is one of the world’s largest providers of the uranium needed to generate clean, reliable baseload electricity around the globe. Our tier-one operations in Canada and Kazakhstan have the licensed capacity to produce more than 53 million pounds (100% basis) each year.

Our operations and projects are diversified by geography and deposit type, backed up by extensive mineral reserves and resources. All of Cameco's operations demonstrate the company's high standards for safety, health and environmental performance.


Cameco and its predecessor companies have been mining uranium for more than 60 years. We have extensive knowledge of all aspects of uranium mining and are global leaders in exploration, mine engineering, environmental protection, and worker health and safety.

Most of Cameco's operating experience is in the Athabasca Basin of northern Saskatchewan, home to the world's largest, high-grade uranium deposits. Mining in this area presents geological, technical and logistical challenges that Cameco has effectively managed using innovative methods such as raise boring and jet boring.

Cameco is also a leader in low-cost in situ recovery (ISR) mining. We use ISR methods at our uranium operations in the United States and Kazakhstan.
