Corporate Presentation

2. Disclaimer
This presentation contains “forward-looking statements,” within the meaning of applicable securities laws, regarding events or conditions that
may occur in the future. Such statements include without limitation the long term effects on the uranium market of events in Japan in 2011
including supply and demand projections; the Company’s timeframe for events leading to and culminating in the commencement of production at
Lost Creek; the technical and economic viability of the Lost Creek Project (including the projections contained in the preliminary analysis of
economics of the Lost Creek Project); receipt of (and related timing of) Record of Decision from the U.S. Bureau of Land Management related to
Lost Creek (including procurement, construction); timing and completion of closing of the Pathfinder transaction; the ability to complete additional
favorable uranium sales agreements and ability to reduce exposure to volatile market; the potential of exploration targets throughout the Lost
Creek Property; and the further exploration, development and permitting of exploration projects including Lost Soldier, the Nebraska property,
Screech Lake and, following a closing, at PMC projects; and whether a re-rating of the Company will occur as production nears. These
statements are based on current expectations that, while considered reasonable by management at this time, inherently involve a number of
significant business, economic and competitive risks, uncertainties and contingencies. Numerous factors could cause actual events to differ
materially from those in the forward-looking statements. Factors that could cause such differences, without limiting the generality of the following,
include: risks inherent in exploration activities; volatility and sensitivity to market prices for uranium; volatility and sensitivity to capital market
fluctuations; the impact of exploration competition; the ability to raise funds through private or public equity financings; imprecision in resource
and reserve estimates; environmental and safety risks including increased regulatory burdens; unexpected geological or hydrological conditions;
a possible deterioration in political support for nuclear energy; changes in government regulations and policies, including trade laws and policies;
demand for nuclear power; weather and other natural phenomena; delays in obtaining or failures to obtain required governmental, environmental
or other project approvals; and other exploration, development, operating, financial market and regulatory risks. Although Ur-Energy Inc.
believes that the assumptions inherent in the forward-looking statements are reasonable, undue reliance should not be placed on these
statements, which only apply as of the date of this presentation. Ur-Energy Inc. disclaims any intention or obligation to update or revise any
forward-looking statement, whether as a result of new information, future events or otherwise.
Cautionary Note Regarding Projections: Similarly, this presentation also may contain projections relating to an extended future period and,
accordingly, the estimates and assumptions underlying the projections are inherently highly uncertain, based on events that have not taken
place, and are subject to significant economic, financial, regulatory, competitive and other uncertainties and contingencies beyond the control of
Ur-Energy Inc. Further, given the nature of the Company's business and industry that is subject to a number of significant risk factors, there can
be no assurance that the projections can be or will be realized. It is probable that the actual results and outcomes will differ, possibly materially,
from those projected.
The attention of investors is drawn to the Risk Factors set out in the Company's Annual Information Form and Annual Report on Form 40-F,
dated March 2, 2012, which are filed, respectively, with the regulatory authorities in Canada on SEDAR and with the U.S. Securities and
Exchange Commission on EDGAR. (www.sedar.com and http://www.sec.gov/edgar.shtml)
Cautionary Note to U.S. Investors Concerning Estimates of Measured, Indicated or Inferred Resources: the information presented uses
the terms "measured", "indicated" and "inferred" mineral resources. United States investors are advised that while such terms are recognized
and required by Canadian regulations, the United States Securities and Exchange Commission does not recognize these terms. United States
investors are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be converted into mineral
reserves. United States investors are also cautioned not to assume that all or any part of an inferred mineral resource exists, or is economically
or legally minable.

Indicated: 4.15 Mlbs eU3O8 (in 3.96 Mt @ 0.053%)
Inferred: 2.87 Mlbs eU3O8 (in 2.99 Mt @ 0.049%)
* Based on grade cutoff of 0.02% eU3O8 and a GT cutoff of 0.3
Updated technical report includes new
claims and upgraded resources
Exploration targets within the Lost
Creek Project and adjoining projects
provide potential of additional
resources U3O8
Lost Creek Project – 4,254 permit acres
Adjoining Projects – ~39,000 acres
Many of these exploration targets remain conceptual in nature. There has been
insufficient exploration to define mineral resource estimates at all such
exploration targets. It is uncertain if further exploration will result in the
additional target areas being delineated as further mineral resource.

Cautionary Statement: This PEA 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 both site-specific
laboratory recovery data as well as URE personnel and industry experience at similar facilities. There can be no assurance that recovery at this level will be achieved.
