Corporate Presentation September 2012


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 (including procurement, construction); 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; 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. John Cooper, Ur-Energy Project Geologist, P.Geo. and SME Registered Member, and Qualified Person as defined by National Instrument 43-101, and Catherine Bull, Ur-Energy Project Engineer, Wyoming P.E., and Qualified Person as defined by the NI 43-101, reviewed and approved the technical information contained in this presentation.

Nuclear Fuel Demand is Growing

US NRC approved four new construction & operation licenses this year (2012)

First nuclear power plant licenses in 30+ years

HEU Agreement to expire next year Provides 13% of world and 45% of US annual supply

63 new reactors under construction

Russia, China and India represent 50% of new builds and have reaffirmed support for nuclear power

Saudi Arabia & the United Kingdom combined have announced plans to build 24 new reactors

8



Global Supply Picture is Dynamic Today’s capital markets present a significant obstacle to development of new large scale mining centers

Current prices do not incentivize new supply development or sustain high cost conventional producers

Large scale production growth is being curtailed for the foreseeable future

Olympic Dam expansion delayed Kintyre shelved No new growth for Paladin under $85/pound

New production will only come from a limited number of low cost, scalable projects

9



The US Uranium Market US Demand is not met by US Production

The US mines produce ~ 4M lbs of uranium/ yr1

The US utilities consume 55M lbs of uranium/ yr1

Ur-Energy is well positioned to capitalize on this opportunity

The Lost Creek Property

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 – ~38,000 acres

15

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.

Measured: 4.20 Mlbs eU3O8 (in 3.85 Mt @ 0.055%) 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

Mineral Resource Increase from February 2012 PEA 45% Increase in Measured and Indicated Resources 42% Increase in Inferred Resources

Estimates Operating Costs at US$16.12/ lb

Lowest quartile of all uranium producers

Project Internal Rate of Return (IRR) at 87%

Pre-Production Capital Costs of Only US$31.6M Remaining Lowest quartile of all developing uranium production facilities

Extended Life of Mine to 8-10 years * Preliminary Economic Assessment of the Lost Creek Property, Sweetwater County, Wyoming Prepared by Ur-Energy Inc. – April 30, 2012 (posted on SEDAR and EDGAR)

18

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.
