Cameco Resources is America's largest uranium producer, providing more than half of domestically produced uranium for nuclear power plants.

We are a wholly-owned subsidiary of Cameco Corporation, one of the world's largest uranium producers. Our US headquarters is in Casper, Wyoming. We own and operate the Smith Ranch-Highland in situ uranium mine near Glenrock, Wyoming, and a satellite in situ uranium mine near Wright, Wyoming – as well as the Crow Butte in situ uranium mine near Crawford, Nebraska. Our central processing plants at Smith Ranch-Highland and Crow Butte produce uranium concentrate that, after further processing elsewhere, becomes fuel for nuclear power plants.
