The NRC issued Source Materials License SUA-1350 to Kennecott Uranium Company in February 1979. The mill was constructed in 1980, operated from 1981 to 1983, and stopped processing ore in 1983 because of low uranium prices. A 2026 corporate filing says the facility was built by Minerals Exploration Company, a Unocal subsidiary, and that the Green Mountain Mining Venture, a joint venture of Kennecott, U.S. Energy and Crested Corp, took it over in fiscal 1993.
