Ur-Energy Presents Upgraded License Application to NRC

DENVER, COLORADO--(Marketwire - March 24, 2008) - Ur-Energy Inc (TSX:URE) ("Ur-Energy" or "Corporation") is pleased to announce the submittal of its improved Source Material License Application to the US Nuclear Regulatory Commission ("NRC") for its Lost Creek ISR Project ("Project").

Lost Creek ISR, LLC, a wholly-owned subsidiary of Ur-Energy, voluntarily withdrew its application for the Project on February 29, 2008 to incorporate certain modifications. Additional data related to the Project operational plans and advancements in the health physics analyses prompted the Corporation to update its NRC License Application. The process was coordinated with the NRC to minimize the impact on the permitting schedule.

"The Ur-Energy team was committed to providing the upgraded application within 30 days of the withdrawal. With hard work and dedication our permitting team prevailed, allowing the Corporation to meet its objective of submitting an application that meets the highest standards. We fully expect the improvements to facilitate the NRC review process," stated Wayne Heili, Vice President of Mining and Engineering.
