UEX Secures Right to Fund $18 Million in Additional Drilling at Shea Creek

These Additional Expenditures would be supplementary to any annual budget proposed by AREVA, as operator, for exploration and development under the current Joint Venture.  Consequently, the amendment will enable the annual shared budgets to focus on other highly prospective targets along the 33 km long Saskatoon Lake Conductor located on Shea Creek or along the many other conductors on the jointly owned projects.

"This agreement provides UEX with a multi-year opportunity to build upon our past successes with AREVA by continuing exploration intended to expand known Shea Creek resources while concurrently seeking new uranium deposits," said Graham Thody, President and CEO of UEX.

Under this amendment, UEX may propose a budget amount of up to $4.0 million in any single year without the prior approval of AREVA. The $18.0 million may be spent over the six-year period ending December 31, 2018.  UEX's interest in the Western Athabasca Projects will increase at the end of each calendar year, pro-rata, based on the amount of Additional Expenditures incurred in such year.  AREVA and UEX will jointly develop these drilling programs and intend to focus efforts at Shea Creek.

Also under this amendment and during the six-year option period, AREVA has agreed to propose a minimum annual budget (to be shared pro-rata) of not less than $2.0 million for the Western Athabasca Projects, inclusive of Shea Creek, provided that UEX proposes to spend at least $2.0 million of Additional Expenditures in the same year and the average weekly spot price of U₃O₈ for the year ended September 30^th prior to such year is not less than $40 per pound of U₃O₈.

Should additional highly prospective mineralized areas be discovered on the Shea Creek Project, or at any of the other eight projects governed by the Joint Venture, UEX and AREVA may jointly agree to spend a portion of the Additional Expenditures in advancing such prospective areas.

UEX and AREVA previously announced an approved $3.1 million budget for exploration to be conducted south of the Anne Deposit beginning this spring and consisting of a $0.5 million geophysical program and a $2.6 million drilling program (see UEX news release dated March 20, 2013).  With the announcement of this amendment to the Joint Venture, UEX and AREVA will be discussing an additional drilling program, expected to follow this previously announced exploration work, and UEX estimates the first budget for Additional Expenditures in 2013 to be between $2.0 million and $3.0 million.  It is anticipated that this additional drilling program will focus, for 2013, on the numerous opportunities to expand the Shea Creek resources, including follow up of the Kianna East and Upper Kianna East zones discovered during the 2012 program.

Should UEX expend the full $18.0 million of Additional Expenditures over the six-year option period, UEX, in addition to the potential expansion of its known resources, will also increase its current in-ground resources of U₃O₈ at Shea Creek by just under 1%.

Shea Creek Project

Shea Creek hosts the Kianna, Anne, Colette and 58B deposits, and is the most advanced of the nine 49%-owned Western Athabasca uranium projects joint-ventured with the project operator, AREVA Resources Canada Inc. The Shea Creek deposits form part of a world-class uranium system in which mineralization has been defined over a strike length exceeding three kilometres along the Saskatoon Lake graphitic conductor in the northern part of the project. Most areas of mineralization continue to be open and have high potential for both expansion and discovery of new zones.

Effective December 31, 2009, UEX reported a combined National Instrument 43-101 ("N.I. 43-101") compliant mineral resource estimate for the Kianna, Anne and Colette deposits of 63.6 million pounds U₃O₈ in the Indicated Mineral Resource category and an additional 24.5 million pounds U₃O₈ in the Inferred Mineral Resource category at a cut-off of 0.3% U₃O₈ (see UEX news release dated May 26, 2010). Further details concerning these resources are provided below.

UEX now anticipates that an updated mineral resource estimate will be completed early in the second quarter of 2013.

About UEX

UEX is a Canadian uranium exploration and development company actively involved in 17 uranium projects, including six that are 100% owned and operated by UEX, one joint venture with AREVA that is operated by UEX, as well as nine joint-ventured with AREVA and one joint venture with AREVA and JCU (Canada) Exploration Company, Limited, which are operated by AREVA. The 17 projects, totaling 264,363 hectares (653,255 acres), are located in the eastern, western and northern perimeters of the Athabasca Basin, the world's richest uranium belt, which accounts for approximately 15% of the global primary uranium production. UEX is currently advancing several uranium deposits in the Athabasca Basin which include the Kianna, Anne, Colette and 58B deposits at its 49%-owned Shea Creek Project, and the Horseshoe, Raven and West Bear deposits located at its 100%-owned Hidden Bay Project. UEX currently has a cash position of approximately $10.9 million.

UEX's two major projects have mineral resource estimates as follows:

UEX Corporation - Indicated Mineral Resources ^{(1) (2) (3)}

UEX Corporation - Inferred Mineral Resources ^{(1) (2) (3)}
