LITTLETON, Colo., Jan. 19, 2016 /PRNewswire/ -- Ur-Energy Inc. (NYSE MKT:URG, TSX:URE)("Ur-Energy" or the "Company") is pleased to announce the completion of an updated Preliminary Economic Assessment ("PEA") for its Lost Creek Property in Sweetwater County, Wyoming, which confirms the increase in mineral resources previously announced, see News Release December 7, 2015. The PEA also serves to update the economic analyses for the Property (December 2013), and replaces the most recent Canadian National Instrument 43-101 (NI 43-101) Technical Report on the Lost Creek Property, dated June 17, 2015, prepared by TREC, Inc. (TREC).

The primary purpose of this PEA is to confirm the updated mineral resource estimate prompted by 2015 drilling within Lost Creek's Mine Unit 2 (MU2) and exploratory drilling at the Lost Creek and LC East Projects. Also included in this estimate is an increase to the overall Property resource total through a re-estimation of all previously-identified resources at a revised 0.20 grade-thickness (GT) cut-off.

The current mineral resource estimate for the Lost Creek Property, after subtracting 1.358 million pounds of uranium produced from MU1 through September 30, 2015, is 13.251 million pounds in the Measured and Indicated categories, and 6.439 million pounds in the Inferred category. The current resource estimate represents a net increase to the Lost Creek Property (all Projects) of:

• 3.146 million pounds eU₃O₈ in the Measured and Indicated categories (after adjustment for MU1 production), or 31% increase when compared with the previous resource estimate in the June 17, 2015 Technical Report; and
• 1.402 million pounds eU₃O₈ in the Inferred category, or a 28% increase to the last mineral resource.

The economic analyses within this PEA continue to demonstrate the potential economic viability of the project.  The analyses have been revised to evaluate the impact of additional identified resources with information and data acquired through two years of ISR operations at Lost Creek. Total future life of mine production is modeled to be 13.8 million pounds and with production operations ending in 2031. This represents a nine year life of mine extension from the forecast contained in the previous PEA.

James Bonner, Vice President, Ur-Energy commented, "We are very pleased with the continued growth and development of the Lost Creek mineral resource. Incorporation of data from existing wellfield pattern drilling and over two years of operations experience gives us a high level of confidence in these mineral resource estimates, and their impact to extend the life of mine at this low-cost producing facility." 

The updated resource estimate is summarized here:

1. Sum of Measured and Indicated tons and pounds may not add to the reported total due to rounding.
2. % eU₃O₈ is a measure of gamma intensity from a decay product of uranium and is not a direct measurement of uranium. Numerous comparisons of eU₃O₈ and chemical assays of Lost Creek rock samples, as well as PFN logging, indicate that eU₃O₈ is a reasonable indicator of the chemical concentration of uranium.
3. Table shows resources based on grade cutoff of 0.02 % eU₃O₈ and a grade x thickness cutoff of 0.20 GT.
4. Measured, Indicated, and Inferred Mineral Resources as defined in Section 1.2 of NI 43-101 (the CIM Definition Standards (CIM Council, 2014)).
5. Resources are reported through October 15, 2015.
6. All reported resources occur below the static water table.
7. 1,358,407 lbs. of uranium have been produced from the HJ Horizon in MU1 (Lost Creek Project) as of September 30, 2015.
8. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

The economic analyses presented in the PEA provide both pre- and post-income tax data. This analysis estimates the Project will generate net cash flow over its life of US$510.9 million (before tax) and US$409.0 million (after taxes).  A summary of the economic analyses is presented here:

1. Initial capital costs of $46.5 million were incurred and expended prior to the starting date (September 30, 2015) of this economic analyses.  Because there are no additional cash expenditures required for initial capital, they are therefore excluded from the cash flow and NPV calculations.
2. As of September 30, 2015, Lost Creek had $41.0 million of undepreciated, initial capital assets that will be charged against operations over time.  By including the undepreciated, initial capital assets, an IRR can be calculated.  Without these costs, an IRR cannot be calculated.

This PEA for the Lost Creek Property has been prepared for Ur-Energy by TREC, Inc., in accordance with NI 43-101 Standards of Disclosure for Mineral Projects. Completion of this PEA was under the direction of Mr. Douglass H. Graves, P.E., representing TREC and Mr. James A. Bonner, C.P.G. (American Institute of Professional Geologists), Vice President Geology, Ur-Energy Inc.  Both individuals are Qualified Persons as defined by NI 43-101. Messrs. Graves and Bonner, Qualified Persons, have reviewed and approved the technical disclosure contained in this news release. 

The full report titled "Preliminary Economic Assessment of the Lost Creek Property, Sweetwater County, Wyoming" dated January 19, 2016, is available on the Company's profile on SEDAR (www.sedar.com) and is also available on the Company's website at www.urenergy.com.  

Cautionary statement: This 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. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The estimated mineral recovery used in this Preliminary Economic Assessment is based on recovery data from wellfield operations to date, as well as URE personnel and industry experience at similar facilities. There can be no assurance that recovery at this level will be achieved.
