13.96% eU3O8 Over 11.8 m Expands Ōrora Zone Discovery New High Grade Zone now has 65 m strike length and remains open along strike

April 5, 2017

UEX Corporation (UEX:TSX) (“UEX” or the “Company”) is pleased to announce assay and radiometric results from the ongoing 2017 exploration program at the  Christie Lake Project, which has successfully  expanded the Ōrora Zone discovery along strike to the southwest.


  • Hole CB-116A encountered high grade mineralization that returned a Radiometric Equivalent Grade (“REG”) of:
  • 13.96% eU3O8 over 11.8 m from 469.2 to 481.0 m at the unconformity including:
  • 23.69% eU3O8 over 4.8 m from 471.3 to 476.1 m

This hole increases the strike length of the newly discovered Ōrora Zone to at least 65 m. Ōrora remains open for expansion along strike to the southwest and to the northeast, along the unconformity to the northwest and down-dip to the southeast into the basement.

Ōrora Zone Expansion Drilling

UEX is reporting the REG results of four additional holes drilled to expand the newly discovered Ōrora Zone.  Results of three of these holes are presented in the table below:

Hole CB-116A intersected mineralization approximately 40 m along strike to the southwest of discovery hole CB-109 (22.81% U3O8 over 8.6 m from 475.1 to 483.7 m – see UEX News Release of February 14, 2017).  Drill core recovery losses were approximately 40% within the mineralized zone and as a result, the REG grade could be more representative of the mineralized interval than any future composite grades based on chemical assays. 

Hole CB-116A-1 was an off-cut of CB-116A targeting the unconformity approximately 10 m northwest and on-section.  CB-116A-1 intersected a wide interval of uranium mineralization that returned an REG of 0.91% eU3O8 over 12.5 m from 474.55 to 487.05 m and included a higher-grade subinterval of 2.90% eU3O8 over 3.1 m from 477.85 to 480.95 m.  Approximately 80% of the core was recovered from this mineralized zone.

Hole CB-114C was drilled to test the Ōrora Zone between discovery hole CB-109 and CB-116A and successfully encountered uranium mineralization averaging 1.33% eU3O8 over 2.0 m from 481.65 to 483.65 m. 

Hole CB-114C-1 intersected anomalous uranium mineralization.  Both CB-114C and CB-114C-1 are believed to have missed the ideal structural target to the southeast.  The ideal structure target is believed to be at the location where the Yalowega Fault intersects the unconformity.

Paul Bay Drilling

The Company also received the assay results from holes CB-112 and CB-113, drilled to test the continuity of the upper high-grade zone of the Paul Bay Deposit.

Hole CB-113 returned a composite assay grade of 5.77% U3O8 over 7.6 m from 494.0 to 501.6 m that included a higher-grade subinterval of 8.48% U3O8 over 4.9 m from 494.6 to 499.5 m, confirming that the high-grade zone is continuous between holes CB-004 and CB-092.

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 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.
