Program Expanded & Second Drill Mobilized

UEX Corporation (UEX:TSX) ('UEX' or the 'Company') is pleased to announce assay results from the first holes of the summer 2016 drilling program and radiometric results from five new holes completed on the Christie Lake Project (the 'Project').

Based upon the results, UEX has elected to expand the budget of the 2016 drill program from $2.75 million to $4 million program. A second drill rig is currently being mobilized to site.

Assay Results from the Paul Bay High Grade Area

The final assay results from the first three drill holes completed during the summer program that tested the High Grade Area within the Paul Bay Deposit are presented below. Radiometric grades from these three holes were previously reported in the UEX News Releases of June 24, 2016 and July 11, 2016.

Assay results from CB-093 far exceeded our expectations. The assays returned a composite grade interval of:

• 14.74% UO over 5.5 m (from 492.2 - 497.7 m), including a subinterval of:
  • 31.77% UO over 2.5 m, which in turn included a subinterval of:

These assay grades far exceeded the previously reported Radiometric Equivalent Grades ('REGs' or 'eUO') of 1.16% eUO over 5.9 m (from 491.75 - 497.65 m).

The large discrepancy between the assay grades and the REGs for CB-093 is the result of the down-hole radiometric probes 'saturating' when encountering very high grade uranium in-situ, a phenomena described in more detail in the UEX News Release of May 24, 2016.

Assay results from CB-092-1 returned grades that corresponded closely to the REGs. The assay composite averaged:

• 2.10% UO over 4.6 m (from 505.1 - 509.7 m) and included a subinterval of:
  • 3.76% UO over 2.4 m (from 507.3 - 509.7 m).

Hole CB-092-2 returned:

• 0.48% UO over 4.3 m (from 509.8 - 514.1 m) and included a subinterval of:
  • 1.67% UO over 1.0 m (from 513.1 - 514.1 m).

The exceptional assay grades from hole CB-093 have extended the zone of semi-massive to massive ultra-high grade uranium mineralization defined by holes CB-093, CB-092 and historic hole CB-004 to a plunge length of 60+ m within the High Grade Area of the Paul Bay Deposit. This Ultra-High Grade Core remains open up-plunge to the northeast (see Figure 1).

Probe Results from Paul Bay Down-Dip Drilling

Five holes have been completed to test the down-dip extent of the Paul Bay Deposit.

REGs from down-hole probe results from hole CB-094 encountered multiple mineralized intervals, the best of which returned 1.04% eUO over 4.8 m (from 616.85 - 621.65 m) and included a section that averaged 1.96% eUO over 1.5 m.

The CB-094 intersection extends the Paul Bay Zone at least 35 m in the down-dip direction below the deepest historic intersection by the previous operators, CB-018. CB-094 is also approximately 25 m northeast of and slightly below UEX hole CB-091B that returned a composite assay grade of 0.28% UO over 7.7 m from 600.0 - 607.7 m (see UEX News Release of May 24, 2016).

Hole CB-095A, drilled to test the Paul Bay Zone approximately 50 m along strike to the northeast of CB-094, encountered anomalous radioactivity and weak hydrothermal alteration, indicating that this hole may have tested the northeast boundary of the Paul Bay Zone at this depth.

Hole CB-094-1 tested the Paul Bay Deposit approximately 25 m below the CB-094 intersection. This hole encountered two narrow intervals of minor uranium mineralization, the best of which returned a probe grade of 0.16% eUO over 0.3 m (from 618.35 - 619.85 m). While hydrothermal alteration and minor uranium were present in this hole and likely continue at depth, the results suggest that the Paul Bay Deposit may now be closed off in the down-dip direction.

Hole CB-096 was drilled to test the down-plunge extent of the Paul Bay High Grade Zone to the west of the known limits of the uranium mineralization. CB-096 did encounter 1.17% eUO over 1.5 m (from 512.75 - 514.25 m) within one of the most intense and strongest hydrothermally-altered package of rocks intersected on the property to date.

Hole CB-096-1 tested the western edge of the deposit approximately 25 m down-dip of CB-096 and also encountered substantial and intense hydrothermal alteration. Uranium was intersected over a narrow interval averaging 0.29% eUO over 1.0 m.

The eUO grades were estimated in-situ within the drill holes using calibrated down-hole radiometric gamma probes. Samples from all holes have been collected for assay analysis to confirm these equivalent grades. The samples will be analyzed at the Geoanalytical Laboratory at the Saskatchewan Research Council in Saskatoon, Saskatchewan, with results expected in the coming weeks. The details on how eUO was calculated from the probe grades were outlined in our press release of May 24, 2016.

Expanded Program and Mobilization of Second Rig to Test the Ken Pen Zone

Based upon the results of the drilling program and the Company's intention to test the Ken Pen Deposit prior to the end of the year, UEX has decided to add a second drill rig to the program. The second rig will commence testing the Ken Pen Zone while the original rig will focus on expanding the Ultra-High Grade Core of the Paul Bay Deposit. The budget for the 2016 Christie Lake Exploration Program has been increased from $2.75 million to $4.0 million.

The Ken Pen Deposit is located approximately 200 m northeast and along strike of the Paul Bay Deposit. High-grade mineralization at Ken Pen is known to be located both at the unconformity and within basement structures below the unconformity. The first holes will focus on expanding mineralization near hole CB-032 which encountered 5.20% UO over 9.20 m in the basement structure.

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.

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 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 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.
