We operate Smith Ranch and Highland in Wyoming as a combined operation. Each has its own processing facility, but the Smith Ranch mill processes all the uranium. The Highland mill is currently idle. Together, they form the largest uranium production facility in the United States.

Cameco Resources intends to expand output at Smith Ranch Highland through construction of an adjacent satellite in situ operation known as Reynolds Ranch whose reserves and resources are now included as part of the Smith Ranch-Highland total.
