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 2013.

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.

Production

Attributable production for 2013 increased by approximately 8% to a record of 13.2 million pounds U₃O₈ 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.

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

Notes:

(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.
(2)	All Mineral Resources and Mineral Reserves are reported in accordance with the definitions and guidelines for the reporting of exploration information, Mineral Resources and Mineral Reserves determined by the Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards on Mineral Resources and Mineral Reserves adopted by the CIM Council (the "CIM Standards") and National Instrument 43-101 - Standards of Disclosure for Mineral Projects promulgated by the Canadian Securities Administrators ("NI 43-101").  Unless otherwise stated, for each project the Mineral Reserves stated above are included in the total estimate of Mineral Resources as stated above. All figures are rounded to reflect appropriate levels of confidence. Columns may not add up correctly due to rounding.
(3)	The above estimates are reported both on a 100% basis and on the basis of the portion of total Mineral Reserves and/or Mineral Resources notionally attributable to Uranium One's equity interest in the joint venture through which South Inkai mine in Kazakhstan is owned.  Uranium One's interest in South Inkai is 70%.
(4)	Mineral Resources based on 0.08 m% (grade x thickness) cut-off per hole.
(5)	Mineral Resources and Mineral Reserves based on bulk density of 1.70 t/m^3.
(6)	Depletion estimated using losses of 10%.
(7)	Measured Mineral Resources based on regular exploration drilling density of 50 m x 200 m (excluding residual and rear wing mineralized bodies).
(8)	Indicated Mineral Resources based on regular exploration drilling density up to 50-100 m x 800 m (excluding residual mineralized bodies) and 50 m x 200 m for residual mineralized bodies.
(9)	Inferred Mineral Resources are based on exploration drilling density of 50-300 m x 400-800 m (excluding residual mineralized bodies) and up to 50-100 m x 800 m for residual mineralized bodies.
(10)	Mineral Resources include Mineral Reserves.
(11)	Mineral Reserves are estimated at a cut-off of 0.08 m%.
(12)	Mineral Reserves are estimated using an average long-term uranium price of US$65 per pound U3O8 (US$169/kg U).
(13)	Uranium quantities and grade for Mineral Reserves are net of extraction.

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 techniques.

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.
