Cameco Corporation (NYSE: CCJ) is one of the world’s largest publicly traded uranium producers, specializing in the exploration, mining, milling and processing of uranium for nuclear power generation. Headquartered in Saskatoon, Saskatchewan, Cameco operates a diversified portfolio of uranium mining assets in Canada and the United States, and holds an interest in uranium production joint ventures in Kazakhstan. The company’s activities span the full spectrum of the fuel cycle, including the production of uranium concentrate (U3O8), conversion services, and fuel manufacturing services for utilities worldwide.
Cameco’s Canadian operations include the McArthur River and Cigar Lake uranium mines in northern Saskatchewan, two of the highest‐grade deposits in the world, as well as the Key Lake processing facility.

In addition to uranium mining, Cameco provides uranium conversion and fuel manufacturing services through its subsidiary, Cameco Fuel Manufacturing, which supplies fuel pellets and fuel assemblies to utilities operating light water reactors. The company leverages established relationships with major nuclear power producers and invests in research and development to enhance its proprietary processing and manufacturing technologies, supporting the long‐term sustainability and safety of nuclear energy globally.

The company emphasizes strong environmental stewardship, community engagement—particularly with Indigenous partners in Canada—and rigorous safety standards across all its operations, aligning with its mission to responsibly supply low‐carbon fuel for clean energy generation worldwide.
