Ur-Energy Enters into Definitive Agreement to Acquire Pathfinder Mines Corporation

LITTLETON, Colo., July 24, 2012 /CNW/ - Ur-Energy Inc. (TSX: URE, NYSE Amex: URG) ("Ur-Energy" or the "Company") is pleased to announce the execution of a Share Purchase Agreement to acquire, through its wholly-owned subsidiary Ur-Energy USA Inc., Pathfinder Mines Corporation ("Pathfinder").

Pathfinder owns the Shirley Basin and Lucky Mc (pronounced "mac") mine sites in the Shirley Basin and Gas Hills mining districts of Wyoming, respectively, from which it historically produced more than seventy-one million pounds of uranium, primarily from the 1960s through the 1990s. Internal historic reports prepared by Pathfinder estimate the presence of remaining resources at the two projects totalling approximately 15 million pounds U₃O₈. These historic reports estimate that the Shirley Basin project holds over 10 million pounds U₃O₈ at a GT (grade-thickness) cut off of 0.25 ft%. The average grade reported for the property is 0.21% U₃O_8. Lucky Mc holds an additional 4.7 million pounds U₃O₈ at similar grade. These historic resource calculations were reviewed by Ur-Energy during a due diligence investigation but a qualified person has not done sufficient work to classify the historical estimates as current mineral resources or mineral reserves under National Instrument 43-101 and Ur-Energy is not treating the historic estimate as current mineral resources or mineral reserves. The tailings facility at the Shirley Basin site is one of the few remaining facilities in the U.S. that is licensed by the United States Nuclear Regulatory Commission ("NRC") to receive and dispose of byproduct waste material from other in-situ uranium mines.

Wayne W. Heili, President and CEO of the Company stated, "I am extremely pleased to announce this acquisition. Adding the Shirley Basin and Lucky Mc properties to our flagship Lost Creek Property and other exploration projects provides Ur-Energy excellent prospects for the expansion of our operations over coming years. This transaction brings a highly accretive set of assets and historic mineral resources."

The transaction calls for the purchase of all issued and outstanding shares of Pathfinder from its sole shareholder, COGEMA Resources, Inc., an AREVA Mining affiliate, for US$13,250,000. The initial payment of US$1,325,000 was made upon execution of the Share Purchase Agreement and will be held in escrow pending the approval by the NRC for the change of control of the NRC License for the Shirley Basin mine site. Subject to that and other regulatory and governmental approvals, together with customary closing conditions, closing of the transaction is anticipated in 6 – 12 months.

Together with property holdings of patented lands, unpatented mining claims, and State of Wyoming and private leases totalling more than 5,100 acres (3,300+ acres at Shirley Basin; 1,800+ at Lucky Mc), the Company acquires all historic geologic, engineering and operational data related to the two areas held by Pathfinder. Additionally, Ur-Energy acquires all historic Pathfinder U.S. exploration and development data in a database estimated to comprise hundreds of project descriptions in more than twenty states, including thousands of drill logs and geologic reports.

John W. Cash, Vice President Regulatory Affairs, Exploration and Geology for Ur-Energy noted, "We are anxious to close the transaction in order to complete an analysis by a qualified person of the historic estimates and to prepare an NI 43-101 compliant mineral resource estimate, as well as to commence baseline studies for the initiation of regulatory applications, initially at the Shirley Basin site. As well, we anticipate that the historic exploration and development databases which are an integral part of this acquisition will provide abundant opportunity for new exploration targets and for resale to third parties."

Both Lucky Mc and Shirley Basin conventional mine operations were suspended in the 1990s due to low uranium pricing and facility reclamation was substantially completed. After closing of the transaction, the Company will assume responsibility to complete the remaining reclamation work at Shirley Basin and at the Lucky Mc mine site. The Lucky Mc tailings site was fully reclaimed and has been transferred to the United States Department of Energy. Ur-Energy will therefore assume no obligations with respect to the NRC License at the Lucky Mc tailings site, which will either be terminated or will be assumed by COGEMA or an affiliate prior to the closing of the transaction.

Finally, various former Pathfinder personnel with decades of invaluable institutional knowledge are available to the Company for some period of time through ongoing consulting agreements.

Ur-Energy also is progressing various opportunities for its Lost Creek Project. The Company awaits the final regulatory authorization for Lost Creek from the U.S. Bureau of Land Management (BLM). The BLM is near completion of its environmental review process following the close of public comments related to a draft environmental impact statement ("EIS") in June. The projected completion date for the Lost Creek Project final EIS, and issuance of a record of decision by the BLM, is anticipated later in the summer of 2012. The NRC and the Wyoming Department of Environmental Quality previously granted approvals for the Project. The Company plans to begin construction at the Lost Creek Project following receipt of the record of decision, followed by production in the spring of 2013.

Ur-Energy is currently in discussions with several financial sources to secure debt financing for the costs associated with the construction and development of the Lost Creek Project plant and initial well field facilities. Although the Company maintains a well funded treasury, the debt instruments being considered would provide additional flexibility to advance the Pathfinder acquisition and pursue other prospective development and acquisition opportunities.
