2016 Program Complete, Preparations for 2017 Underway

VANCOUVER, BC--(Marketwired - December 15, 2016) - UEX Corporation (TSX: UEX) ("UEX" or the "Company") is pleased to announce the final assay results from the summer 2016 drilling program on the Christie Lake Project (the "Project").

2016 Exploration Commitments and Goals Achieved

Our focus in 2016 was to improve our understanding of the mineralization on the Christie Lake Project and to grow the Paul Bay and Ken Pen Deposits. Highlights of our achievements in 2016 included:

• Confirmed and expanded the mineralization at the Ken Pen and Paul Bay deposits
• Discovered an unexpected high grade zone of mineralization within Paul Bay
• Successfully applied lessons learned at Paul Bay to the Ken Pen area, which led to the discovery of additional unconformity mineralization
• Discovered a possible second high grade zone at Paul Bay

UEX has met its 2016 work commitment requirement under the UEX-JCU Christie Lake Option Agreement and has banked almost $1.5 million towards the 2017 work commitment. Upon making the 2017 property payment, our ownership interest in Christie Lake will increase from 10% to 30%. The Company remains on track to earn its full 70% interest in the Project.

"In my view, Christie Lake has some of the best deposit growth potential in the Athabasca Basin and I'm looking forward to our 2017 drilling program".

- Roger Lemaitre, President & CEO

Winter Drill Program Preparations Underway

A winter 2017 program is being planned, with the goals of expanding the mineralization at Ken Pen and Paul Bay, as well as testing northeast along the Yalowega Trend. Outside of the Ken Pen and Paul Bay deposits, sporadic historic drilling encountered both unconformity and shallow basement mineralization along the Yalowega Trend. Our team is eager to apply our improved area knowledge to the Yalowega Trend targets.

Preparations for the winter drill program are currently underway. As many of the Yalowega-trend drill targets are best drill tested in the winter from lake ice platforms, UEX has mobilized a team to the Project to adequately thicken the lake ice in advance of an early January drilling program.

Assay Results from the Ken Pen Area

The assay results from the drill holes completed during the summer program at the Ken Pen Deposit are presented below. Radiometric equivalent grades ("REGs") from these holes were previously reported in the UEX News Release of November 7, 2016. Assay results were generally in line with the previously reported REG results.

Assay Results from Paul Bay Area

Assay results for the final holes completed to test the extent of the Paul Bay Deposit are presented below and were generally in line with the previously reported REG results.

Assay grades from holes CB-104 and CB-096 were lower than the previously reported REGs because approximately half the core was recovered from these mineralized intervals. Thus, the assay samples are not considered to be representative of these actual mineralized intervals.

Sample Collection and Compositing

Drill core is split in half sections on site and one half is collected for U₃O₈ (wt %) analysis with the other half core remaining on site for reference. Where possible, samples are collected at a standardized 0.5 m interval through zones of mineralization but respect geological units and intervals.

The samples are shipped to the Geoanalytical Laboratory at the Saskatchewan Research Council ("SRC") in Saskatoon, Saskatchewan. Analysis at the SRC laboratory for uranium as U₃O₈ (wt %) was completed using the ICP-OES method. The SRC Geoanalytical Laboratory is an ISO/IEC 17025:2005 accredited facility (#537) by the Standards Council of Canada.

Assay intervals were composited using a cut-off grade of 0.1% U₃O₈. All depth measurements and sample intervals reported are down-hole measurements from drill core. True thickness of the mineralized zones has yet to be determined.

About the Christie Lake Project

UEX currently holds a 10% interest in the Christie Lake Project and is working under an option agreement to earn up to a 70% interest. The Project is located approximately 9 km northeast and along strike of Cameco's McArthur River Mine, the world's largest uranium producer. The P2 Fault, the controlling structure for all of the McArthur River deposits, continues to the northeast beyond the mine. UEX believes that through a series of en-echelon steps the northeast strike extension of the P2 Fault not only crosses the Project but also controls the two known uranium deposits on Christie Lake, the Paul Bay and Ken Pen Deposits.

The Paul Bay and Ken Pen Deposits are estimated to host a combined 20.87 million pounds of U₃O₈ at an average grade of 3.22% U₃O₈ and were discovered in 1989 and 1993 respectively. This is a historic resource estimation which does not use resource classifications consistent with NI 43-101. The historical resource estimate was presented in an internal report titled Christie Lake Project, Geological Resource Estimate completed by PNC Tono Geoscience Center, Resource Analysis Group, dated September 12, 1997. The historical resource was calculated using a 3 D block model using block sizes of 2 m by 2 m by 2 m, and block grades interpolated using the inverse distance squared method over a circular search radius of 25 m and 1 m height. Specific gravities for each deposit were averaged from specific gravity measures of individual samples collected for assay. UEX plans to complete additional infill drilling on the deposits during the option earn-in period to upgrade these historic resources to indicated and inferred. A qualified person has not done sufficient work to classify the historic estimate as current mineral resources or mineral reserves. UEX is not treating the historic estimate as current mineral reserves or mineral resources.
