Ur-Energy Announces Approval of Lost Creek Development Plan by Sweetwater County

DENVER, COLORADO -- (MARKET WIRE) -- 12/03/09 -- Ur-Energy Inc. (TSX: URE)(NYSE Amex: URG)("Ur-Energy" or the "Company") is pleased to announce the approval of its Lost Creek Project Development Plan by the governing officials of Sweetwater County Wyoming, where the project is located. The Development Plan was submitted by Lost Creek ISR, LLC, a wholly-owned subsidiary of the Company.

On December 1, 2009, the Sweetwater County Commissioners unanimously approved the Development Plan for the Lost Creek Project. The Development Plan describes in detail the infrastructure and facilities which will be constructed at the planned uranium ISR production site. This approval is the culmination of two years of cooperative work with the County which included rezoning of the permit area from agriculture to mining and a total of five public meetings. No opposition to the project was voiced at any of the public meetings.

Prior to consideration by the County Commissioners, the Development Plan was scrutinized by the County Engineering Department and forwarded to the County's Planning and Zoning Commission for review. After due consideration, the Planning and Zoning Commission voted 5-0 in September 2009 to recommend approval of the requested plan. Going forward, the County Planning and Zoning staff will review construction plans to ensure all applicable building, electrical and fire safety codes are met and commitments in the Development Plan are adhered to. With the approval of the Commissioners, no additional public meetings are required by the County.

John Cash, Manager of EHS and Regulatory Affairs stated, "Lost Creek ISR, LLC cooperatively participated in the re-zoning and Development Plan processes because the County plays a significant role in maintaining site access and planning for and responding to emergency situations. We believe the collaborative effort with the County has resulted in improved facility design and emergency response capabilities."

Wayne Heili, Vice President of Mining and Engineering added, "Ur-Energy sincerely appreciates the involvement of the Sweetwater County staff and officials in the planning of the Lost Creek Project. The well-informed and overwhelming support of the Sweetwater County government and its people is a great demonstration that Southwestern Wyoming is indeed the right jurisdiction to be developing new mineral resource projects."
