NEWS RELEASE.

April 26, 2012: Littleton, Colorado – Ur-Energy Inc. (Stock Profile – TSX:URE & AMEX:URG) released its annual letter to shareholders from President and CEO, Wayne W. Heili. 2011 marked some major developments at the company’s flagship Lost Creek property in Wyoming.

Lost Creek Property

• Regulatory Advances: The principal focus of the Company continues to be the advancement of the Lost Creek Project to final licensing.  We were pleased to announce the receipt of our Nuclear Regulatory Commission License for the Lost Creek Project in August 2011.  This accomplishment was followed by the receipt of the Wyoming Department of Environmental Quality Permit to Mine in October.  The Company also received from the US Environmental Protection Agency the approval of an aquifer exemption that allows Class-III injection into the mineralized horizon.  We had been granted our Class-I UIC permit for the necessary waste water disposal wells in 2010.  With the successful conclusion of these major permitting actions, the Company now awaits the only remaining authorization required to commence facility construction from the US Bureau of Land Management (BLM).  While the progress of the BLM’s environmental review did not track with the other major licensing actions, steady progress has been made.  Current guidance from the BLM suggests that the Final Environmental Impact Statement and Record of Decision will be issued during the summer of 2012.
• Uranium Resource Base Increases:  Efforts initiated in 2011 and reported in early 2012 have resulted in a 58% aggregate growth of the Lost Creek Property Measured and Indicated resources from 5.3 Mlbs U₃O₈ to 8.35 Mlbs U₃O₈. We have also added over 2.0 Mlbs U₃O₈ to our Inferred resource inventory. Our work leads us to conclude that there is significant potential for the continued definition of additional resources through exploration on the Lost Creek Property.  The resource growth was realized through our two-pronged approach to demonstrate the scalability of the Lost Creek Property:

1. Resource Expansion Drilling: We completed a successful drill program in 2011 that allowed our technical team to upgrade the resources defined on the Lost Creek Property. In February 2012, we completed an update to the NI 43-101 Preliminary Economic Assessment (PEA) of the Lost Creek Property. The PEA expanded the Lost Creek Property Measured and Indicated Resource by 11%.  For the first time, we reported resources that are located within our Lost Creek Property holdings but outside of the Lost Creek Project area.  Our LC North and LC South Projects now each have reported Inferred mineral resources.  As a result, the Inferred Resource at the Lost Creek Property increased by 159%.
2. Property Acquisitions:  In February 2012, the Company acquired approximately 5,250 acres (2,124 hectares) of property adjacent to the Lost Creek Project in an asset exchange with Uranium One Americas.  The acquired property interests, along with 253 newly staked federal mining claims encompassing approximately 4,430 acres (1,792 hectares) were incorporated into the Lost Creek Property, primarily as our new LC East and LC West Projects.  The Company owns an historic database containing over 1,100 drill holes located on these new project areas.  The database has been utilized to estimate the mineral resources for LC East and LC West without incurring drilling expenses.  On April 4, 2012 the Company announced a 45% increase (from the February PEA) in Measured and Indicated Resources along with a 42% increase in Inferred Resources for the Lost Creek Property.

• Economic Assessment: Our February 2012 update to the PEA for the Lost Creek Property continues to demonstrate that Lost Creek is technically and economically viable.  The PEA estimates direct operating costs of less than $20/lb which places Lost Creek in the lowest quartile of all uranium production facilities. Note: Cautionary statement pursuant to NI 43-101: the Preliminary Economic Assessment is preliminary in nature, and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. The estimated mineral recovery used in this PEA is based on site-specific laboratory recovery data as well as Company personnel and industry experience at similar facilities.  There can be no assurance that recovery at this level will be achieved.
• Project Design Engineering: Current indications are that the final BLM authorization will be on hand in time to begin construction in the summer of 2012.  Ur-Energy is prepared to break ground very soon after this final permitting action.  Our technical group has continued to prepare the detailed engineering and design work for the project facilities along with the initial uranium recovery areas.
