UEX Corporation : UEX Announces Additional $2.0 Million Drilling Budget for Shea Creek 2013 Exploration Program

UEX Corporation ("UEX") is pleased to announce an additional 2013 exploration budget for drilling on the Shea Creek Project ("Shea Creek") of $2.0 million. This program will be funded by UEX under the recent agreement signed with AREVA Resources Canada Inc. ("AREVA"), which was announced in UEX's news release dated April 10, 2013.

This 2013 supplemental drilling program of approximately 4,000 metres is designed to test open portions of the high-grade Kianna East mineralized zone as well as open portions of the northern part of the Kianna Deposit ("Kianna North") (see Figure 1 for drilling area). Considerable exploration success was achieved in both of these areas from 2010 through 2012. This program represents a commitment by UEX to further the expansion of mineral resources at the Kianna Deposit ("Kianna").

This supplemental program is in addition to the $3.1 million program announced in March 2013, of which UEX is responsible for funding $1.52 million, consisting of a $0.5 million geophysical program in the northern Colette and southern Anne Deposit areas and a $2.6 million 5,000-metre drilling program south of the Anne Deposit (see Figure 1 and UEX's news release dated March 20, 2013).

The drilling south of the Anne Deposit and in the Kianna area will be conducted concurrently utilizing two drill rigs and will commence in early June 2013. Drilling rigs will be mobilized shortly. The geophysical program commenced in May 2013.

Kianna East

Kianna East represents a shallow southwest-dipping zone of mineralization which lies approximately 80 to 110 metres below and east of the main Kianna basement zone and about 200 metres below the unconformity (see Figure 2). Given the orientation of the drill holes, the Kianna East intercepts lie at or close to true thickness. Significant previous results from drilling at Kianna East, which were incorporated into the recently announced 2013 Mineral Resource Estimate (as defined below), include:

SHE-135-11* 3.59% eU3O8 over 16.0 metres;
SHE-135-13* 3.70% eU3O8 over 18.1 metres;
SHE-118-24** 1.55% eU3O8 over 19.9 metres; and
SHE-135-12** 2.36% U3O8 over 7.0 metres.

* see UEX's news release dated October 15, 2012
** see UEX's news release dated November 14, 2012

This high-grade zone occurs parallel to and along the top of a southwest-dipping graphitic unit which forms an electromagnetic (EM) anomaly to the east of, and parallel to, the Saskatoon Lake Conductor (see Figure 1 inset). The new zone is open to the northwest, southeast and up dip to the northeast. Drilling will test for the potential of the new basement zone to continue along strike and to extend upward along the graphitic unit toward the unconformity.

Kianna North

This area, also referred to as the GAMP Zone, includes a zone of mineralization which lies to the north of the main Kianna basement zone and was initially intersected in 2010. During that program, drill hole SHE-136-1 intersected 1.84% eU3O8 over 16.6 metres approximately 50 metres to the north of the main Kianna basement zone. Subsequent drilling intercepts in the area include 1.28% eU3O8 over 25.1 metres in hole SHE 130 4 drilled in 2011. This zone of mineralization, which was incorporated into the 2013 Mineral Resource Estimate, is still open to the east. Additional mineralized intercepts, which lie outside of this resource, define further prospective targets for similar mineralization styles.

Recent Developments at Shea Creek

Results of drilling at Kianna East and Kianna North were incorporated into the recent updated National Instrument 43-101 independent mineral resource estimate for Shea Creek ("2013 Mineral Resource Estimate") (see UEX's news release dated April 17, 2013) which, at a cut-off grade of 0.30% U3O8, totals:

• 67.66 million pounds of U3O8 in the Indicated mineral resource category comprising 2,067,900 tonnes grading 1.48% U3O8; and
• 28.19 million pounds of U3O8 in the Inferred mineral resource category comprising 1,272,200 tonnes grading 1.01% U3O8.

The updated mineral resource estimate reflects the success of UEX and AREVA in expanding Kianna which, together with the contiguous Anne Deposit ("Anne"), represents a substantial portion of the Shea Creek resource. The Anne and Kianna deposits at a cut-off grade of 0.30% U3O8 contain:

• 59.6 million pounds of U3O8 in the Indicated mineral resource category comprising 1,598,500 tonnes grading 1.69% U3O8; and
• 19.5 million pounds of U3O8 in the Inferred mineral resource category comprising 695,600 tonnes grading 1.27% U3O8.

The April 4, 2013 agreement with AREVA provides UEX the option to spend up to $18.0 million over the next six years on exploration in addition to the amount agreed to annually by the Western Athabasca Joint Venture ("WAJV"). During the term of this option, UEX will increase its interest in the WAJV projects on a pro-rata basis for exploration amounts expended. UEX can spend up to $4.0 million annually without prior approval of the WAJV, a limit designed to ensure AREVA, the operator, has sufficient personnel to conduct any exploration program put forth. Another feature of the agreement is that the floor level of minimum budgets for the WAJV has been increased during the term of the agreement. UEX may gain not only a further interest of 0.9% in the existing resource, but also up to 49.9% of any further resources discovered. This agreement provides UEX with a multi year opportunity to build upon past successes with AREVA by continuing exploration intended to expand known Shea Creek resources while concurrently seeking new uranium deposits along the many graphitic conductors identified on the WAJV projects.

Cautionary Note to United States Investors

This press release has been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of U.S. securities laws. Unless otherwise indicated, all resource estimates included in this press release have been prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining, Metallurgy, and Petroleum Definition Standards on Mineral Resources and Mineral Reserves. NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, differ significantly from the requirements of the United States Securities and Exchange Commission ("SEC"), and resource information contained herein may not be comparable to similar information disclosed by U.S. companies. In particular, and without limiting the generality of the foregoing, the term "resource" does not equate to the term "reserves". Under U.S. standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. The SEC's disclosure standards normally do not permit the inclusion of information concerning "measured mineral resources", "indicated mineral resources" or "inferred mineral resources" or other descriptions of the amount of mineralization in mineral deposits that do not constitute "reserves" by U.S. standards in documents filed with the SEC. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves. U.S. investors should also understand that "inferred mineral resources" have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an "inferred mineral resource" will ever be upgraded to a higher category. Under Canadian rules, estimated "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies except in rare cases. Investors are cautioned not to assume that all or any part of an "inferred mineral resource" exists or is economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in-place tonnage and grade without reference to unit measures. Accordingly, information concerning mineral deposits set forth herein may not be comparable with information made public by companies that report in accordance with U.S. standards.
