Denver, Colorado (Marketwire – January 11, 2010) Ur-Energy Inc. (TSX:URE, NYSE Amex:URG) (“Ur-Energy” or the “Company”) announces Bayswater Uranium Corporation (TSX-V: BYU)(“Bayswater”) has completed a National Instrument 43-101 (“NI 43-101”) technical report for Ur-Energy’s wholly-owned subsidiary Hauber Project LLC (the “Hauber Project”). Ur-Energy and Bayswater completed a venture agreement in December 2009 by which Bayswater, as an earn-in member of the venture, may earn a 75% interest in Hauber Project with the expenditure of US$1 million eligible exploration expenses over a four-year period as previously announced December 1, 2009.

Bayswater, as Manager of Hauber Project, commissioned Thomas C. Pool, P.E., of International Nuclear, Inc., based in Golden, Colorado, to complete an independent NI 43-101 mineral resource estimate of the properties at the Hauber Project. The resource estimate concludes the Hauber Project properties hold approximately 1.45 million pounds of eU3O8 (Indicated Resources) in 423,000 tons at an average grade of 0.17% eU3O8. Bayswater will file the completed NI 43-101 technical report on www.sedar.com shortly.

The Company’s properties at the Hauber Project, in Crook County Wyoming, include 205 unpatented lode mining claims and one State of Wyoming Uranium Lease, for a combined total of approximately 5160 acres. The identified uranium occurrences on the Hauber Project occur in the Lower Cretaceous Lakota and Fall River formations, and are along the trend of the nearby historic Hauber mine, operated by Homestake Mining from 1958 to 1966. During that period, Homestake produced over 2.6 million pounds of U3O8 by underground mining methods.

Bill Boberg, President and CEO of Ur-Energy, stated, “We are pleased with the prompt completion by Bayswater of a NI 43-101 technical report on the Hauber Project properties. We welcome this additional work on the Project to establish compliant resources, and we look forward to the drill program and other work planned by Bayswater during 2010.”
