Uranium Energy Corp Intersects 6.28% eU3O8 Over 2.9 metres in a 25 metre Step Out from the Roughrider East Zone Deposit

Press Release

Corpus Christi, TX, January 31, 2024 – Uranium Energy Corp (NYSE American: UEC, the “Company” or “UEC”) is pleased to report drill results from its Roughrider Project located in Northern Saskatchewan, Canada. Both exploration and metallurgical sample drilling have been successful at intersecting uranium mineralization.

  • Exploration drilling extends potential of East Zone deposit: UEC commenced a drill program at Roughrider in November 2023 with the dual purpose of exploring for additional resources on the property and for collecting metallurgical samples in the existing resource areas to support future economic studies.
  • Discovery of new high-grade vein hosted mineralization in hole RR-889 grading 6.29% eU3O8 over 2.9 metres (“m”) ~25 m west of the East Zone deposit (“East Zone”): The mineralization is consistent with the grades and thicknesses of the East Zone and provides targets for resource expansion.
  • Metallurgical drill program at Roughrider completed: UEC has completed four metallurgical holes that intersected grades and thicknesses of uranium mineralization consistent with the resource models of the three zones, the best result being hole RR-879, drilled through the East Zone, which graded 3.16% eU3O8 over 43.4 m with sub-intervals grading 4.05% eU3O8 over 12.6 m and 3.81% eU3O8 over 21.6 m (Table 1).
  • Roughrider next steps: UEC plans to drill an additional 20 holes comprising about 9,000 m this winter to identify new areas of uranium mineralization. The current resource estimate includes 27.8 million lb U3O8 comprising 389,000 tonnes grading 3.25% U3O8 in the Indicated category and 36.0 million lb U3O8 comprising 359,000 tonnes grading 4.55% U3O8 in the Inferred category1.

Chris Hamel, Vice President Exploration, Canada stated: “Roughrider is a world-class project with untapped potential for resource expansion and we’re pleased to confirm this with the discovery of high-grade mineralization between the East and West Zone deposits. The drilling program will continue through the winter and focus on exploration for additional uranium that is outside the existing mineralized zones.

Additionally, our metallurgical drilling has also confirmed the high-grade and vein-hosted nature of the Roughrider deposit with grades and thicknesses consistent with resource modelling and its structural setting.  Our competitive advantage is the combination of the foundational work by Hathor and Rio Tinto with the UEC Canada Roughrider Team’s proven track record in brownfields resource expansion.”

About Canada’s Athabasca Basin

The Athabasca Basin is a world-class uranium district in the northern portion of the provinces of Saskatchewan and Alberta in Canada, occupying an area of about 100,000 square kilometres. The unique geology of the Athabasca Basin often results in deposit grades that exceed the world average of uranium deposits of 0.2% U3O8 by up to 100 times.

All of Canada’s current uranium production occurs from the mines located in the Athabasca Basin. According to the World Nuclear Association, the Athabasca Basin was responsible for producing 15% of the world’s uranium production in 2022.

Uranium mineralization in the Athabasca Basin occurs in fault structures that penetrate the interface between the sandstone and underlying basement rocks. Uranium can be found at the interface, known as the unconformity, or up to several hundreds of metres below the unconformity surface in the underlying basement rock and fault structures.

The uranium concentrations in the holes presented above from the radiometric equivalent uranium grade (“REG”), denoted as eU3O8, were determined in-situ within the drill hole. For more information on REGs please see the “About Radiometric Equivalent Grades” section below.

About Radiometric Equivalent Grades

The eU3O8 grades were estimated in-situ within the drill holes using calibrated down-hole radiometric gamma probes lowered down into the hole. This is a measuring method commonly used by uranium explorers and miners in the Athabasca Basin. The probe records the amount of radioactivity present in the rock adjacent to the probe as it moves up and down the hole.

The standard and shielded probes were calibrated prior to the commencement of the current drill program at the Saskatchewan Research Council’s (“SRC”) test pit facility in Saskatoon, Saskatchewan, and the Hi-Flux probes are calibrated at Alpha Nuclear in Saskatoon. Using down-hole probes to calculate radiometric equivalent grades is a common practice used by uranium mining companies in the Athabasca Basin. Down-hole probes can accurately measure uranium concentration by measuring the light flashes that occur every time the probe’s scintillator is struck by a gamma radiation particle emitted from uranium crystals. The number of light flashes are ‘counted’ by a photomultiplier tube. Due to a process called ‘saturation’ that occurs when light emitted by the probe’s scintillator overwhelms the photomultiplier tube’s ability to ‘count’ individual light flashes, it can sometimes be difficult to accurately determine radiometric equivalent grades in high-grade intervals.

Samples from all holes have been collected for assay analysis to confirm these equivalent grades. The samples will be analyzed at SRC’s Geoanalytical Laboratory in Saskatoon, with results expected in the coming weeks.

About the Roughrider Uranium Project

The Roughrider Project is a uranium project located in the eastern Athabasca Basin of northern Saskatchewan, Canada; one of the world’s premier uranium mining jurisdictions. The project is located approximately 13 kilometres west of Orano’s McClean Lake Mill, near UEC’s existing Athabasca Basin properties. The depth to mineralization at the project is approximately 200 m and hosted primarily in the basement rocks below the unconformity.
