Exhibit 99.1

Ur-Energy Receives Draft Supplemental Environmental

Impact Statement (SEIS) for the Lost Creek Project

Denver, Colorado (Marketwire – December 9, 2009) Ur-Energy Inc. (TSX:URE, NYSE Amex:URG)  (“Ur-Energy” or the “Company”) is pleased to announce the release of the Lost Creek Project Draft Supplemental Environmental Impact Statement (SEIS) by the U.S. Nuclear Regulatory Commission (NRC).  The document was prepared for Lost Creek ISR, LLC (LCI), a wholly-owned subsidiary of the Company.

In early December 2009, the NRC released the Draft SEIS for Ur-Energy’s Lost Creek Project.  The NRC staff prepared this SEIS to evaluate the potential environmental impacts from LCI’s proposal to construct, operate and decommission an ISR uranium facility at the Lost Creek Project site.  The NRC staff preliminarily finds that, unless safety issues mandate otherwise, environmental impacts of the proposed issuing of a source material license are not so great as to make issuance an unreasonable decision.  The NRC staff is continuing its safety evaluation and has also completed its internal Draft Safety Evaluation Report (SER) document for the project.  The positive recommendation of the Draft SEIS document is an indication of significant progress toward the approval of the NRC license application of the Lost Creek Project.

Bill Boberg, President and CEO of Ur-Energy commented, “Ur-Energy is now realizing the benefits of the dedicated efforts of its staff to work cooperatively with the Federal, State and local regulatory agencies.  We look forward to the anticipated completion of these efforts in 2010.”
