UEX Corporation (UEX:TSX) ('UEX' or the 'Company') is pleased to report the chemical assay results of the first three drill holes of 2016 completed this winter on the Christie Lake Project (the 'Project') (see Figure 1) where a $2.75 million drill program is scheduled to recommence in the first week of June. The Project is owned 10% by UEX and 90% by JCU (Canada) Exploration Company Limited ('JCU'). UEX holds an option to earn up to a 70% interest in the Project.

Radiometric Equivalent Grades ('REGs') from down-hole probe results were previously reported on April 13, 2016. Systematic assays were collected from the mineralized zones to confirm the REGs. Due to the significant uranium grades encountered, the REGs underreported actual UOgrades.

Assay Highlights

Highlighting the assay results was hole CB-092, which returned a much higher than expected composite assay intersection when compared to the previously reported REGs:

• 9.30% UO over a 9.8 m interval from 496.6 - 504.4 m, including:
  • 43.71% UO over 2.0 m from 500.1 - 502.1 m

This is a substantially higher composite grade than the radiometric equivalent grade of 4.27% eUO over 10.2 m, as previously reported on April 13, 2016. The assay results of CB-092 confirm it is the highest grade hole ever drilled on the Christie Lake Project to date.

Hole CB-090A returned a composite assay grade of:

• 0.61% UO over 9.8 m from 534.2 - 544.0 m, including:

The composite assay grade of CB-090A also exceeded the previously reported radiometric equivalent grade of 0.38% eUO over 9.1 m.

Hole CB-091B was previously reported to have hosted minor uranium mineralization that occurred in several narrow and widely spaced intervals. The assay results of CB-091B showed higher than anticipated grades in these intervals that generated a composite assay grade of 0.28% UO over 7.7 m from 600.0 - 607.7 m.

Upon receiving the assay results, Roger Lemaitre, President and CEO of UEX Corporation stated,

'The return of such impressive assays at Christie Lake showcases the unusually high-grade potential of the Christie Lake Deposits. Our exploration team is eager to get back in the field and pick up where they left off in April.'

About Radiometric Equivalent Grades and Assay Grades

While using down-hole probes to calculate radiometric equivalent grades is a common practice by uranium mining companies in the Athabasca Basin, down-hole probes are often unable to accurately measure uranium concentration within high-grade intervals, due to a process called 'saturation' which occurs when light emitted by the probe's scintillator overwhelms the photomultiplier tube's ability to 'count' individual light flashes (the scintillator flashes light every time it is struck by a gamma radiation particle).

In the case of hole CB-092, the high-grade core of the mineralized interval returned individual assay sample grades of 5.63% over 0.5 m, 39.4% over 0.5 m, 59.8% over 0.5 m and 70.0% UO over 0.5 m. These assay results confirm the high-grade uranium potential of the Christie Lake Project which occurs along the same P2 Fault trend that hosts Cameco's McArthur River mine.

Sample Collection and Compositing

Drill core is split in half sections on site and one half is collected for UO (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 UO (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.

Duplicate samples were sent to the SRC Environmental Analytical Laboratory in Saskatoon, Saskatchewan for check-assaying using the Neutron Activation Analysis technique via the SRC's Slowpoke-2 reactor.

Assay intervals were composited using a cut-off grade of 0.1% UO. All depth measurements and sample intervals reported are down-hole measurements from drill core. True thickness of the ore 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 UO at an average grade of 3.22% UO 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.
