Ur-Energy Progresses With Permitting of Lost Creek Project

LITTLETON, COLORADO -- (Marketwire) -- 08/29/11 -- Ur-Energy Inc. (TSX: URE)(NYSE Amex: URG) ('Ur-Energy' or the 'Company') is pleased to announce that the Wyoming Department of Environmental Quality ('WDEQ') has reclassified a portion of the production aquifer within the Lost Creek permit area as Class V (Mineral Commercial). The U.S. Environmental Protection Agency ('EPA'), in a letter dated August 23, 2011, formally agreed with WDEQ's reclassification and in turn has issued an aquifer exemption pursuant to the requirements in 40 CFR section 146.4. Both the WDEQ aquifer reclassification and the EPA aquifer exemption are required before injection into the uranium recovery wellfields can begin. The aquifer reclassification and exemption area includes all of the commercially producible uranium mineralization currently known and included within the Nuclear Regulatory Commission License area (see August 17, 2011 release for more information). This area encompasses all of the currently planned wellfields and will therefore not require changes in the foreseeable future.

EPA's issuance of the aquifer exemption, in agreement with the WDEQ's reclassification, means the only remaining WDEQ action required is the final approval and issuance of the Permit to Mine. Mr. Steve Hatten, VP of Operations, stated, 'We are very pleased that the WDEQ and EPA have accepted the scientific methodology presented by Lost Creek for defining the aquifer exemption. This method will allow for the in situ recovery of uranium while protecting surrounding aquifers and ensuring compliance with the Safe Drinking Water Act.'
