Uranium One Announces 8% Increase in 2013 Production to 13.2 Million Pounds and Updated Mineral Reserve and Resource Estimates

Uranium One Announces 8% Increase in 2013 Production to 13.2 Million Pounds 
and Updated Mineral Reserve and Resource Estimates for the South Inkai Mine 
TORONTO, Feb. 25, 2014 /CNW/ - Uranium One Inc. ("Uranium One") today 
announced attributable production of 13.2 million pounds for the full year 
Uranium One also announced today new and significantly increased mineral 
resource and reserve estimates for its South Inkai uranium mine in Kazakhstan, 
including a 429% increase in measured and indicated resources. 
Attributable production for 2013 increased by approximately 8% to a record of 
13.2 million pounds U(3)O(8 )compared to 12.2 million pounds produced in 2012. 
A breakdown of Uranium One's attributable production for the full year 2013 is 
shown below.

    (1)      Production in commissioning from Honeymoon was 0.2 million
             pounds during 2013. The Honeymoon Mine was placed on care and
             maintenance in November 2013.

Updated Mineral Reserve and Resource Estimates for the South Inkai Uranium Mine

As at December 31, 2013, the total attributable reserves and resources at the 
Company's South Inkai mine in Kazakhstan increased as follows:
        --  the Company's attributable share of proven and probable
            reserves increased by 282%, from 9.24 million lbs U3O8 (3,554 t
            U) to 35.34 million lbs U3O8 (13,593 t U);
        --  the Company's attributable share of measured and indicated
            resources increased by 429%, from 10.27 million lbs U3O8 (3,949
            t U) to 54.36 million lbs U3O8 (20,911 t U); and
        --  the Company's attributable share of inferred resources
            increased by 58%, from 31.12 million lbs U3O8 (11,969 t U) to
            49.08 million lbs U3O8 (18,877 t U).

The new estimates, finalized in late January 2014 following review and 
verification by the Company's Qualified Person, result from the application of 
3D modeling techniques to an extensive database of Kazakh Government drilling 
information which was made available to the Company for the first time.

Further information, including a breakdown of mineral resource and reserve 
estimates for South Inkai, is attached as Appendix A to this news release.

    (1)       Mineral Resources that are not Mineral Reserves do not have
              demonstrated economic viability.  Inferred Mineral Resources
              have a great amount of uncertainty as to their existence and
              as to their economic feasibility.  Under no circumstances can
              it be assumed that all or any part of an Inferred Mineral
              Resource will ever be upgraded to a higher Mineral Resource
              category or converted to Mineral Reserves.

              stated above are included in the total estimate of Mineral

              appropriate levels of confidence. Columns may not add up

Mineral Resource and Reserve Estimation

In September 2013, CSA Global Pty Ltd. ("CSA") was engaged by Uranium One to 
prepare new resource and reserve estimates for South Inkai following the 
provision by the Government of Kazakhstan for the first time of an extensive 
database of previously unavailable drilling data. Previously, estimates for 
the Company's mines in Kazakhstan were prepared in accordance with the Russian 
resource classification system (using a 2D polygonal geological modelling and 
estimation process) and then converted to the CIM resource classification 
system.  Direct access to the raw drilling data enabled the preparation for 
the first time of resource and reserve estimates at South Inkai using the 
application of internationally recognized and more exhaustive 3D modelling 

The resource estimates for South Inkai were prepared by CSA and reviewed by 
Roscoe Postle Associates Inc. ("RPA"), and RPA also prepared the reserve 
estimates under contract to CSA starting in September 2013. RPA used CSA's 
South Inkai resource block models to prepare the reserve estimates.  CSA 
re-estimated the global mineral resources for the deposit, using a new 
wireframe model and interpolation of grades into the block model based on the 
existing drilling data collected to date.  RPA applied a 90% extraction rate, 
the same rate as used in previous estimates, because it is supported by the 
extraction curves from the site.

Qualified Persons

Except as otherwise noted, Mr. M.H.G. Heyns, Pr.Sci.Nat. (SACNASP), MSAIMM, 
MGSSA, CIM, Senior Vice-President of Uranium One, is the Qualified Person who 
prepared or supervised the preparation of the information that forms the basis 
of the scientific and technical disclosure on the Company's mineral properties 
contained in this press release.  The resource estimates for the South Inkai 
mine were prepared for the Company by independent consultants CSA, under the 
supervision of its Qualified Person, Dr. Maxim Seredkin, Senior Resource 
Geologist, and the reserve estimates were prepared by RPA, under the 
supervision of its Qualified Person, Mr. Dennis Bergen, P. Eng., Associate 
Principal Mining Engineer.
