Final Ōrora Assays Received, Summer Program Confirmed, CFO Change

May 23, 2017

UEX Corporation (UEX:TSX) (“UEX” or the “Company”) is pleased to announce that the last outstanding assays from the winter drilling program have been received from holes testing  the Ōrora Zone at the Christie Lake Project.

A two-phase exploration drilling program with a combined budget of up to $2.5 million has been approved by the project partners with the sole focus of expanding the Ōrora Zone.  Preparations for the summer campaign, including exploration permitting, are currently underway.  UEX anticipates commencing the summer drill program in late June.

Ōrora Zone Assay Results

  • Hole CB-116A-1, an off-cut hole drilled to test the width of mineralization on Section 6725N, intersected uranium mineralization at the unconformity ~10 m northwest of CB-116A returned:
  •  0.76% U3O8 over 12.5 m from 474.0 to 486.5 m and included a subinterval of
  • 2.00% U3O8 over 3.5 m from 477.5 to 481.0 m.
  • Hole CB-116A-2 encountered a wide interval of uranium mineralization, extending from the unconformity into the basement, and returned assay intervals of:
  • 0.77% U3O8 over 18.0 m from 466.0 to 484.0 m that included subintervals of
    • 1.77% U3O8 over 6.5 m from 477.5 to 484.0 m, which in turn includes
      • 3.06% U3O8 over 3.5 m from 477.9 to 481.4 m.

These composite assay intervals confirm the REG grades previously reported in UEX’s News Release of April 26, 2017.  True widths are anticipated to be approximately 80-85% of the mineralized core length.

The Ōrora Zone discovery has so far been defined over a minimum strike length of 65 m and has a width of at least  20 m at its southwestern end.  The ultimate width of the Ōrora Zone at the unconformity has not yet been defined by drilling.  Most importantly, Ōrora remains open for expansion along strike to the southwest and to the northeast and down-dip to the southeast into the basement.

Due to extensive core loss within the mineralized interval in hole CB-109-1, the Company was unable to confirm the results of the radiometric equivalent grades in this hole announced in the UEX News Release of April 26, 2017 (0.24% eU3O8 over 1.5 m from 467.65 to 469.15 m).  Assays from a minor mineralized interval located 22 m down hole from this REG interval returned minor uranium mineralization averaging 0.34% U3O8 over 0.4 m from 490.3 to 490.7 m.

For a location of the Ōrora Zone mineralized intersections, please refer to Figure 1. 

Ōrora Summer Drill Program Approved

UEX and JCU have approved a summer program with the sole objective of expanding the size of the Ōrora Zone.  Initially, the program will be focused on expanding the Ōrora Zone in 25 m increments along strike in the direction of historic uranium mineralized hole CB-049, located approximately 75 m to the southwest of hole CB-116A (see Figure 1).   UEX is also planning to target extension of the Ōrora Zone to the northeast along strike, and down-dip into the basement.

The summer campaign is a two-phase program with a combined budget of up to $2.5 million utilizing two drills and will consist of up to 20 drill holes totaling 9,000 m.  UEX will be using directional drilling to assist with targeting precision, reducing the overall meterage needed to test for extensions of the Ōrora Zone.

CFO Change

UEX announces that Mr. Ed Boney is no longer the Chief Financial Officer (CFO") of the Company.  Roger Lemaitre, the Company's CEO, will act as Interim CFO while the Company conducts an executive search to identify a permanent CFO.  Continuity in financial reporting in the interim will be handled by the Company's Manager of Financial Reporting, Valerie Chen, CPA, CA.

About Radiometric Equivalent Grades

The eU3O8 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 eU3O8 was calculated from the probe grades were outlined in our press release of May 24, 2016.

About the Christie Lake Project

UEX currently holds a 30% 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 three known uranium deposits on Christie Lake, the Ōrora, 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 and the reader is advised not to rely upon this historical estimate as a resource estimate.
