Ur-Energy Inc. announced last week that it has begun in situ recovery (ISR) operations at its Shirley Basin uranium mining site in central Wyoming.
The company, which also operates the Lost Creek ISR project in south-central Wyoming, decided to begin construction at Shirley Basin after making a “go” decision in March 2024. It has said that the combined total annual licensed production and toll processing capacity of Lost Creek and Shirley Basin is 4.2 million pounds U₃O₈.

Ur-Energy Inc. has secured approval from the Wyoming Department of Environmental Quality’s Land Quality Division to construct and operate up to six additional mine units at its Lost Creek in situ uranium mine in south-central Wyoming. With that late April approval in hand, “we await only final concurrence and approval of the related aquifer exemption from the U.S. Environmental Protection Agency,” the company said. That approval was granted just three days later, on May 1, but Ur-Energy doesn’t plan to expand Lost Creek for “several years.”

U.S. uranium production increased throughout 2024, with more growth planned in 2025. The producers who can make that happen, however, were burned before by a “renaissance” that didn’t take off. Now they are watching and waiting for signals from Washington, D.C., including the impacts of tariffs, shifting relationships with global uranium producers, and funding for the enrichment task orders designed to boost demand for U.S. uranium.
