Ur-Energy's Lost Creek NRC Application Moves Forward

DENVER, COLORADO -- (MARKET WIRE) -- 06/17/08 -- Ur-Energy Inc (TSX: URE) ("Ur-Energy" or the "Corporation") is pleased to announce that the United States Nuclear Regulatory Commission (NRC) has deemed the Corporation's application to construct and operate the Lost Creek ISR project, Sweetwater County, Wyoming acceptable. The NRC will now commence a detailed technical and environmental review of the Corporation's application, which the NRC strives to complete in 150 days.

Ur-Energy, acting through its wholly-owned subsidiary Lost Creek ISR, LLC, submitted an upgraded Source Material License Application for the Lost Creek ISR project on March 20, 2008. The application was made available through NRC's Agencywide Documents Access and Management System (ADAMS) on April 14, 2008. A copy of the NRC acceptance letter is also available on ADAMS.

On May 22, 2008, the Corporation announced that the Wyoming Department of Environmental Quality (WDEQ) found the Lost Creek ISR project Permit to Mine Application to be complete. This is the first permit application to advance past the WDEQ's completeness review in recent years. The WDEQ has initiated its technical review of the Corporation's application and likewise strives to complete the technical review in 150 days.

"The acceptance of these two applications is a significant measure of progress for the Lost Creek project. Having passed both review phases is attributable to the thoroughness of our personnel to prepare and submit applications of the highest caliber," stated Ur-Energy's President and CEO, Bill Boberg. "Ur-Energy is ready for the next phase of the application process, and we look forward to working with both these agencies to advance the Lost Creek ISR project to production."
