Ur-Energy (URG) Reopens Wyoming Uranium Mine After 34 Years

Ur-Energy Inc.

The Shirley Basin mine is recognized for its historical significance as the birthplace of ISR uranium mining in the U.S. This reopening follows 34 years of inactivity since 1992, with active uranium capture from Mine Unit 1 already underway.
