Best Ever Christie Lake Hole Returns 22.81% U3O8 over 8.60 m New Ōrora Zone Discovery Extended Along Strike
February 14, 2017
UEX Corporation (UEX:TSX) (“UEX” or the “Company”) is pleased to announce results from the first four holes completed on the 2017 exploration program at the Christie Lake Project (the “Project”).
- Discovery Hole CB-109 returned a composite assay grade of 22.81% U3O8 over 8.60 m from 475.1 to 483.7 m, by far the highest grade hole ever drilled on the Christie Lake Project
- Follow-up hole CB-110A has successfully expanded the new high-grade zone 20 m along strike to the northeast and intersected 6.29% eU3O8 over 7.40 m from 471.85 to 479.25 m
- This new zone has been named the Ōrora Zone and remains open for expansion in all directions
- Hole CB-108A intersected 3.25% eU3O8 over 6.70 m from 599.75 to 606.45 m and CB-108A-1 returned 3.35% eU3O8 over 10.63 m from 592.09 to 602.72 m. These two holes expand the high-grade area surrounding CB-102 within the Paul Bay Deposit
Assay Results - Discovery Hole CB-109
UEX previously announced that hole CB-109 discovered a new high-grade zone of off-scale unconformity-style uranium mineralization along the Yalowega Mineralized Trend (see News Release of January 30, 2017), 500 m northeast and along strike of the known deposits (see Figure 1).
Assays received by the Company from Hole CB-109 are outlined in the table below.
|From (m)||To (m)|
|that also includes||479.20||482.80||3.60||42.25%|
|* True widths are estimated to be approximately 90% of core length.|
This intersection makes hole CB-109 the highest-grade hole ever drilled on the Christie Lake Project.
Follow-up Drilling Expands Strike Length of the Ōrora Zone
Hole CB-110A successfully expanded the Ōrora mineralized zone by intersecting high-grade uranium mineralization 20 m northeast and along strike of CB-109. Radiometric Equivalent Grade (“REG”) results of CB-110A are outlined in the table below.
|From (m)||To (m)|
|that also includes||474.95||478.65||3.70||11.88%|
|* True widths are estimated to be approximately 90% of core length.|
While considered to be unconformity-style uranium, the mineralization in CB-110A was situated very slightly below the unconformity indicating that the ideal structural target (as tested by CB-109) may be located northwest of the CB-110A intersection.
Expansion Potential of the Ōrora Zone
The Ōrora Zone currently has a minimum strike length of 20 m and remains open for expansion in all directions (see Figure 1). UEX will be following-up these results with additional drilling during the ongoing winter program.
With these results, UEX eagerly anticipates what the remainder of the winter program will reveal. Along the 1.5 km long Yalowega Trend, only three holes have successfully tested the unconformity where it is intersected by the lower breccia unit. Two of these holes intersect the Ōrora Zone as we have currently defined it. The third is UEX hole CB-104, a high-grade hole which tested the Ken Pen Zone 500 m to the southwest. Clearly, we have a lot of exciting work ahead of us to properly investigate the potential of this previously unrecognized uranium-bearing feature.

The potential for the discovery of basement-hosted mineralization akin to the Paul Bay Zone also remains untested along most of the length of the Yalowega Trend.
Paul Bay Deposit Drilling
This winter UEX is also drilling within the Paul Bay Deposit to tighten up drill hole spacings both within the Upper High Grade Zone and the area surrounding CB-102, which encountered unexpectedly high-grade mineralization within the lower third of the deposit. These tighter spacings are required to finalize UEX’s first NI-43-101 resource report on the Christie Lake Project, which is scheduled for completion by the end of the second quarter.
Hole CB-108A intersected multiple zones of basement-hosted mineralization approximately 15 m southwest and at a slightly lower elevation than CB-102.
Offcut hole CB-108A-1 tested the Paul Bay Deposit approximately 28 m northeast and at a slightly higher elevation than CB-102 and also encountered multiple mineralized intervals. The REG results of CB-108A and CB-108A-1 are outlined in the table below:
|From (m)||To (m)|
|* True widths are estimated to be approximately 80-85% of core length.|
Both of these holes will have a significant impact on the resource model of the lower part of the Paul Bay Deposit.
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 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.
