UEX Corporation (UEX:TSX) (“UEX” or the “Company”) is pleased to announce the second tranche of assay results from the winter drilling program on the Company’s 100% owned West Bear Property, located in the eastern Athabasca Basin of northern Saskatchewan. In January, UEX commenced a $4.25 million 110-160 drill hole program at West Bear with the objective of expanding the size of the West Bear Cobalt-Nickel Deposit (the “Deposit”) by extending cobalt mineralization along strike to the west.
To date, the Company has completed 110 holes of this winter’s exploration program and drilled 9,780 metres. Assay results have been received for thirty-six drill holes. UEX announced assay results from the first five holes in the Company’s news release dated February 7, 2019, available at www.sedar.com or UEX’s website at www.uex-corporation.
Thirty of the 31 holes from the second batch of assays returned composite grades that exceed the cobalt equivalent (“CoEq”) grade of 0.023% CoEq, the same cut-off grade used in UEX’s maiden resource estimate for the West Bear Cobalt-Nickel deposit announced on July 10, 2018 available at www.sedar.com or UEX’s website at www.uex-corporation.
While the Company has been expanding the West Bear Cobalt-Nickel Deposit along strike to the west and in the area below the existing West Bear Uranium Deposit (the “Uranium Deposit”), UEX has also reviewed results from the sonic drill holes that defined the Uranium Deposit during the 2005 and 2007 exploration campaigns. Of the 214 sonic holes drilled, 99 holes encountered cobalt and nickel mineralization exceeding 0.023% CoEq within rock located below the Uranium Deposit and specifically excluded from the volume of rock comprising the Uranium Deposit. Twenty-six of these holes returned composite assay results exceeding 0.25% CoEq of which 10 holes exceeded 0.5% CoEq. Assay results specific to cobalt and nickel mineralization occurring below the Uranium Deposit have never been announced by the Company, as these results were recently compiled for the first time.
Highlights from the current drill program include hole WBC-047 which encountered widespread cobalt and nickel averaging 0.05% Co and 0.16% Ni over 27.50 m from 27.50 m to 55.00 m, and hole WBC-070 which intersected 0.06% Co and 0.16% Ni over 11.00 m from 25.50 m to 36.50 m (see Tables 1 and 3).
Highlights from the review of the historic sonic drilling programs included holes UEX-043 which intersected 0.815% Co and 1.357% Ni over 8.4 m from 23.60 m to 32.00 m (including a subinterval of 1.512% Co and 1.963% Ni over 3.0 m from 29.00 m to 32.00 m), UEX-051 that averaged 0.416% Co and 2.197% Ni over 1.2 m from 23.30 m to 24.50 m, UEX-056 which assayed 0.425% Co and 1.362% Ni over 3.0 m from 24.80 m to 27.80 m and UEX-057 which intersected 0.449% Co and 2.085% Ni over 3.1 m from 22.90 m to 26.00 m (see Tables 2 and 4).
With the available results from the current drilling program and a review of the historic sonic holes, the strike length of the West Bear Deposit has been increased from 400 m to 550 m (see Figure 1) with the majority of assays from the 2019 program yet to be received.

UEX is encouraged by the results of the current drilling program and by the surprising results from the sonic drill program review.
The reader is cautioned that the results from the sonic drill program can be difficult to interpret. Technical limitations on the depth of penetration of sonic drill rigs meant that in most cases drill holes were terminated prior to being able to fully penetrate into and/or through the fault structure that hosts the cobalt-nickel mineralization below the Uranium Deposit. As a result, sonic holes were often terminated in cobalt-nickel mineralization. In 2007, the Company was focussed exclusively on defining the Uranium Deposit and in many cases did not completely sample the rocks and fault structures that host the cobalt and nickel mineralization encountered below the Uranium Deposit. As a result, UEX geologists will be reviewing the existing sonic drill holes and extending sampling coverage to ensure that all possible extensions to the West Bear Cobalt-Nickel Deposit are defined.
With the demand for electric vehicles increasing, we see the need for ethically-sourced cobalt from safe mining and geopolitical jurisdictions to power those cars. Our winter drill results continue to grow our West Bear Cobalt-Nickel Deposit, one of the few known North American cobalt deposits. The Company is eagerly awaiting the assay results of the final holes of the winter program.

Sample Collection and Compositing
Samples are selected using a portable X-Ray Fluorescence (“XRF”) Spectrometer to aid in the identification of mineralized intervals. Selected drill core is then split in half sections on site and one half is collected for 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. Samples collected by UEX in 2005 and 2007 during the sonic drilling programs did not use an XRF Spectrometer to aid in identification of mineralization.
The samples were shipped to the Geoanalytical Laboratory at the Saskatchewan Research Council (“SRC”) in Saskatoon, Saskatchewan. Analysis at the SRC laboratory for Cobalt and Nickel was completed using the ICP-OES method with an Aqua Regia digestion. 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 0.023% Cobalt equivalent (CoEq) using the equation CoEq = Co + (Ni x 0.2). All depth measurements and sample intervals reported are down-hole measurements from drill core.
About the West Bear Cobalt-Nickel Deposit
The West Bear Property is an advanced exploration project located in the eastern Athabasca Basin of northern Saskatchewan, Canada that contains both the West Bear Cobalt-Nickel Deposit and the West Bear Uranium Deposit. The Property is approximately 740 kilometres north of Saskatoon, west of Wollaston Lake and measures approximately 7,983 hectares comprising of 24 contiguous areas to which UEX has 100% ownership, with the exception of Mineral Lease 5424 in which UEX owns a 77.575% interest. The Deposit is located within an area of the Athabasca Basin that has excellent infrastructure and is situated within 10 km of an existing all-weather road and power lines that service Cameco Corporation’s nearby Cigar Lake Mine and Rabbit Lake Operation, as well as Orano’s McClean Lake Operation.
The West Bear Cobalt-Nickel Deposit currently has a strike length of over 550 m and a dip length of over 100 m. On July 10, 2018, the Company announced a maiden inferred resource estimate for the Deposit of 390,000 tonnes grading 0.37% cobalt and 0.22% nickel, which equates to 3,172,000 pounds of cobalt and 1,928,000 pounds of nickel. The West Bear Cobalt-Nickel Deposit mineral resources were determined using a cut-off grade of 0.023 percent cobalt equivalent (“CoEq”), using the equation CoEq = Co + (Ni x 0.2). Only mineralization located within a conceptual open pit was included in the final resource estimate.
