Ōrora assays return 20.00% U3O8 over 8.5 m at Christie Lake

April 26, 2017

UEX Corporation (UEX:TSX) (“UEX” or the “Company”) is pleased to announce assay and radiometric results from the winter 2017 drilling program at the Christie Lake Project, where we successfully  expanded the Ōrora Zone and identified the potential for extending uranium mineralization down-dip into the basement.


  • Hole CB-116A confirmed the high-grade Radiometric Equivalent Grade (“REG”) results with assays averaging:
    • 17.11% U3O8 over 10 m from 471.0 to 481.0 m that included a subinterval of:
      • 20.00% U3O8 over 8.5 m from 471.0 to 479.5 m
  • Hole CB-116A-2 encountered a wide interval of uranium mineralization, extending from the unconformity to approximately 36 m into the basement, and returned an REG of:
  • 0.81% eU3O8 over 28.8 m from 467.15 to 495.95 m that included subintervals of;
    • 3.42% eU3O8 over 4.0 m from 477.45 to 481.45 m, and
    • 2.84% eU3O8 over 2.1 m from 493.85 to 495.95 m.

CB-116A-2 increases the width of the new discovery along its southwestern margin to a minimum of 20 m, the widest section Ōrora Zone mineralization encountered at the unconformity to date. Ōrora remains open for expansion along strike to the southwest and to the northeast and down-dip to the southeast into the basement.


Ōrora Zone Expansion Drilling

Our team has begun to understand the orientation of the Ōrora deposit.  Holes CB-109 and CB-116A have identified an ultra-high grade structural trap ranging from 8 to 16m wide, skirted by a halo of uranium mineralization.  We are eagerly anticipating the summer drill program when we will be growing Ōrora by targeting this key structural feature along the Yalowega Trend.

UEX is reporting the assay and REG results of six holes drilled to expand the newly discovered Ōrora Zone.  Results of these holes are presented in the tables below:

Table 1 – Assay Results from the Ōrora Zone

Assays from hole CB-116A confirm the very high grade nature of the mineralization from which REGs were previously reported (see UEX News Release of April 4, 2017). Despite the significant core loss, the assays correlate well with the REGs.

Hole CB-114C was drilled to test the Ōrora Zone between discovery hole CB-109 and CB-116A and successfully encountered uranium mineralization.  Hosted in basement rocks, the main mineralized interval in CB-114C averaged 2.58% U3O8 over 3.0 m from 481.5 to 484.5 m approximately 10 m below the unconformity.  A second mineralized interval was encountered in the basement rocks below the main Ōrora mineralized zone.

Assays from CB-114C-1 returned three narrow and anomalously uranium-bearing intersections.

Table 2 – REG Results from the Ōrora Zone

Hole CB-116A-2 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) and 8 m southeast of CB-116A (which encountered 13.96% eU3O8 over 11.8 m from 469.2 to 481.0 m – see UEX News Release of April 4, 2017).

A significant portion of the mineralization in CB-116A-2 is hosted below the unconformity (at 469.3 m in hole depth), down-dip of mineralization in CB-116A within the basement rocks. 

For a map of the Ōrora Zone intersections, please see Figure 1.

The results of holes CB-116A-2, CB-114C and historic holes CB-050 and CB-075 suggest that the Ōrora Zone mineralization may exhibit both classic unconformity and basement style mineralization, similar to UEX’s Shea Creek Deposits and Cameco’s Key Lake Mine. 

Assays results from several Ōrora Zone holes have yet to be received by the Company.

Paul Bay Drilling

The Company also received the assay results from hole CB-112-1, drilled to test the continuity of the upper high-grade zone between holes CB-092 and CB-093.  CB-112-1 returned better than expected composite results averaging 3.60% U3O8 over 1.8 m from 497.6 to 499.4 m.

Program Suspended for Spring Break-Up and Future Drilling Plans

This winter, UEX completed 18 holes totaling 8,171 m of the planned 20 hole – 12,000 m drill program.  Significant meterage was saved from the plan after the discovery of the Ōrora Zone, which required the use of in-hole wedging to accurately hit its targets. Amounts not expended during the winter program will be combined with the summer Christie Lake drilling program.

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.
