Smith Ranch-Highland

  • The combined operations at Smith Ranch (including the North Butte satellite mine) and Highland form the largest uranium production facility in the United States.
  • Cameco operates both ISO 14001 certified Wyoming locations, which opened in 1975 and 1972 respectively, and uses the environment-friendly in situ recovery mining method.

Q1 2017 Update
