(TSX:URE, NYSE MKT:URG) ("Ur-Energy" or the "Company") provides the following update regarding construction activities at its Lost Creek Project and the petition for review filed recently in U.S. District Court (see Ur-Energy News Release dated November 13, 2012).

Ur-Energy President and CEO Wayne Heili commented, "The Company has now taken steps to directly protect its interests in the Lost Creek Project." The Company has filed the legal papers necessary to seek to become a party to the petition for review, which seeks judicial review of the Bureau of Land Management (BLM) Record of Decision (ROD) on the Lost Creek Project. The Company's papers also ask the Court to allow the Company to file a brief in opposition to a motion for preliminary injunction which has been filed by the petitioner. The State of Wyoming has filed similar pleadings requesting that it also be permitted to be heard in the case. The Company currently anticipates that the motion for preliminary injunction will be heard by the Court before the end of the year.

There is a second, separate, request for administrative review of the BLM ROD which was made to the State Director of the BLM last month. Recently, the State Director accepted the request for review, while denying the related request to stay construction at the Lost Creek Project.

Construction activities continue at the Lost Creek Project: the east and west access roads are complete. The first and second disposal wells are installed, with subsurface completion activities scheduled this month, and the pad is constructed for the third disposal well. Construction of utilities is also advanced with the powerline to the processing plant complete and the main pipeline connecting the first mine unit to the plant ready to be installed. The plant pad is graded and the installation of cement pylons is complete. A significant portion of tankage and pumping equipment has been received at the site and will be set after the plant floor is poured and cured. Wellfield construction is also progressing as planned with initial drilling of more than 200 holes.
