Ur-Energy Maintains Production Schedule While Exploring for New Discoveries-Webcast Tomorrow

DENVER, COLORADO -- (MARKET WIRE) -- 07/25/07 -- Ur-Energy Inc. (TSX: URE) ("Ur-Energy" or "the Company") is pleased to announce today that its permitting and engineering work is progressing on schedule, with positive results, and a vigorous exploration program has been initiated.

Bill Boberg, President & CEO stated, "Ur-Energy's corporate objectives are three-fold:

1) To start producing uranium in Wyoming by 2009;

2) To be a low cost producer of uranium and not be impacted by lower uranium prices; and,

3) To extend and expand our production pipeline through aggressive development and exploration programs in the US, exploration programs in Canada and through strategic acquisitions.

Our work to date in 2007 demonstrates our strong commitment to meeting those objectives. We are very encouraged by our development work to date at Lost Creek. We congratulate our superb mining team for maintaining a rigorous schedule to accomplish our goals. We are particularly pleased that our projected costs of production at our Lost Creek project will make us a low cost producer and profitable at spot uranium prices considerably below today's prices."

Due to extensive due diligence regarding the Company's May 2007 financing, the normal quarterly report to shareholders was not possible, so there is six months of activities to report on at this time.

Management of Ur-Energy invites you to join them for a Webcast at 11:00 AM Eastern Time, this Thursday, July 26, 2007, to update interested shareholders on the fast-tracking of its Wyoming uranium projects. Instructions for joining the Webcast are as follows:

Lost Creek Project

The Lost Creek uranium deposit is located four miles north of Rio Tinto's Sweetwater mill in the Great Divide Basin, Wyoming. The deposit is approximately three miles (4.8 kilometres) long and the mineralization occurs in four main sandstone horizons between 315 feet (96 metres) and 700 feet (213 metres) in depth. NI 43-101 Compliant Resources (Roscoe Postle Associates Inc., June 15, 2006) for Lost Creek are: 9.8 million pounds of U3O8 at 0.058% as an indicated resource and an additional 1.1 million pounds of U3O8 at 0.076% as an inferred resource. In 2006, seventeen cased monitoring and pump test wells were completed on the property and the initial testing was completed successfully with encouraging results.

Four drill rigs are presently drilling at Lost Creek and the addition of a fifth rig has been scheduled. The drilling is to complete several separate phases of work on the project:

 - Installation of pump test and monitor wells for baseline and engineering
 - Ore body delineation wells to better define the ore body for wellfield
 - Condemnation wells to assure that the plant site will not be built on an
   ore deposit.
 - Water wells for water for the drilling operation.

The following work at Lost Creek was completed during the past six months
and additional work is planned for the remainder of 2007:

- A second round of pump testing was completed demonstrating above average
   flow rates and favourable conditions for ISR mining. A third round of
   pump testing is planned for August 2007.
 - 29 of 59 pump test and monitoring wells have been installed to date,
   with the remainder to be installed during 2007.
 - 32 delineation drill holes of 195 delineation holes have been completed.
   The extensive delineation drilling program is to define the outer limits
   of mineralization for engineering wellfield design.
 - 2 additional water wells were completed away from the delineated
   wellfields.  One of the water wells intercepted 12 feet (3.7 metres) of
   uranium-bearing sandstone at a grade of 0.075 % U3O8.  This is within
   the main mineralized zone, but more than 2,400 ft. (732 metres) from
   known mineralization indicating a possible major extension of
   mineralization within the main mineralized zone.
 - 6 condemnation drill holes reaching up to 1,000 feet (305 metres) in
   depth were completed in the proposed plant site areas.
 - Mineralized intercepts in the 2007 drilling program continue to indicate
   that the mineralization at Lost Creek is commonly thicker than average
   mineralized roll fronts in the basin.  Examples are: LC45 in the HJ Sand
   was 27 feet (8.2 metres) thick at a grade of 0.121% U3O8 and LC49 in the
   KM Sand was 25 feet (7.6 metres) thick at a grade of 0.064% U3O8.
 - Engineering feasibility studies being conducted by the Ur-Energy in-
   house engineering team are well underway, including wellfield design and
   processing plant design.
      - A proposed new processing plant is being designed and permitted to
        produce 2 million pounds of U3O8 yellowcake slurry per year with
        the capability to toll process loaded resin from other satellite
        ISR facilities.
      - Capital equipment orders for long lead time items will be placed
        early in 2008.
      - Instead of building a satellite plant for resin loading, as
        anticipated in the preliminary plans, Ur-Energy will construct a
        full scale processing plant which will be completed in stages. The
        first stage will produce yellowcake slurry and, at a later date, a
        second stage will add a drying and packaging facility.
 - The Ur-Energy License Permit Application to the US Nuclear Regulatory
   Commission ("NRC") for Lost Creek is being compiled into report form
   based on the extensive individual geologic, engineering and
   environmental studies completed by Ur-Energy since starting the
   permitting process in July 2005.
      - The projected date for submission of the Ur-Energy License Permit
        to the NRC is September 2007.  This is projected to be the first
        new ISR (non-satellite) mining license application from Wyoming in
        recent years.
      - The Application for the Ur-Energy Permit to Mine will be submitted
        to the Wyoming Department of Environmental Quality ("WDEQ")
        following the license submission to the NRC.
 - All environmental baseline studies have been completed and our
   contractor, AATA International, is compiling the permit applications for
   both the NRC and the WDEQ.
 - Evaluation and permitting of Class I deep disposal well sites is being
   done by Petrotek Engineering.
 - The 2007 budget for Lost Creek is approximately US$8 million.

Regarding the preparation of the Applications for Permit to Mine at Lost Creek, Bill Boberg, Ur-Energy President & CEO, stated, "We are still on time and within budget to complete and submit our application for Permit to Mine at Lost Creek this September. Drilling at Lost Creek has been identifying several new areas for potential expansion of our resource base, and we expect that drilling during 2007 will increase the Lost Creek resources. Our staff and contractors have been doing an excellent job of moving the Lost Creek project forward. I fully expect that the quality of our applications will be a model that the agencies will use in evaluating future applications. We will be the first new production by a junior uranium company in the state of Wyoming."

Lost Soldier Project

The Lost Soldier project is located approximately 14 miles (22.5 kilometres) to the northeast of the Lost Creek project. The property already has over 3,700 historic drill holes defining 14 mineralized sandstone units. NI 43-101 Compliant Resources (Roscoe Postle Associates Inc., July 10, 2006) for Lost Soldier are: 5 million pounds of U3O8 at 0.064% as a measured resource, 7.2 million pounds of U3O8 at 0.065% as an indicated resource and 1.8 million pounds of U3O8 at 0.055% as an inferred resource.

 - All environmental baseline studies have been completed, with baseline
   groundwater and meteorological data collection is on-going.
 - A scoping study is being completed by Pincock, Allen & Holt Engineering.
   This study will include an evaluation of the mineability of additional
   shallow uranium resources which are above the water table and were not
   included in the Ur-Energy NI 43-101 compliant resource base for Lost
 - The 2007 budget for Lost Soldier is approximately US$1 million.
