CanAlaska Uranium summer drilling confirms extension of Pike Zone Mineralization, Saskatchewan
CanAlaska Uranium Ltd. [TSXV: CVV; OTCQX: CVVUF; FSE: DH7] reported that it has received the geochemical assay results from the 2025 summer drill program completed on the Pike Zone at the West McArthur Project, Saskatchewan.
During the summer program, the company focused on continued step outs from the Pike Zone high-grade mineralization and successfully expanded the mineralized footprint of the Pike Zone at the unconformity to 500 metres length. Geochemical assay results confirm the previously reported eU3O8 results and highlight the strong hydrothermal alteration, intense structural disruption, and uranium mineralization increasing to the southwest along the C10S trend for approximately 250 metres away from the high-grade pod at the Pike Zone. Importantly, the western-most drill fences from the summer program were highlighted by unconformity uranium mineralization in drillholes WMA099 which intersected 2.5 metres at 0.78% U3O8 and WMA099-03 which intersected 3.3 metres at 0.53% U3O8, associated with strong alteration and structural disruption. The company believes these drillholes highlight the potential for additional mineralized pods along the C10S corridor.
CanAlaska CEO, Cory Belyk, commented, “The CanAlaska team is very pleased with these confirmatory geochemical assays being received within a few months of summer program completion. The results clearly highlight the western end of the currently defined 500 metre Pike Zone footprint as increasing in uranium grade. When coupled with the reported structural disruption, alteration and trace metal enrichments, the western end of Pike Zone presents an exciting opportunity for further definition of high-grade uranium mineralization in the coming months.”
The 2025 summer drill program on the West McArthur project consisted of twenty-two unconformity tests, eleven of which contained uranium mineralization. The results of the summer drill program, combined with the results from recently completed drill programs, indicate that the mineralized footprint of the Pike Zone at the unconformity has now been traced over 500 metres with a 140-metre-long high-grade pod outlined by multiple drill fences.
Most importantly, the last drill fences of the summer drill season completed on the western-most step out intersected strong unconformity-associated uranium mineralization. Drillholes on these fences were highlighted by WMA099 which intersected 2.5 metres at 0.78% U3O8 and WMA099-03 which intersected 3.3 metres at 0.53% U3O8. Results from the summer drill program indicate the hydrothermal alteration, structural intensity, and uranium mineralization remain open and appear to be increasing to the west along the C10S trend, highlighting the potential for additional zones of high-grade unconformity uranium mineralization.
As a secondary goal, one infill drillhole was completed during the summer drill program within the high-grade footprint of the Pike Zone in support of the geological model. WMA094-08 intersected multiple intervals of high-grade uranium mineralization, highlighted by 4.2 metres at 5.04% U3O8 along L25E. WMA094-08 confirmed extension and continuity of the high-grade pod to the south along this drill section.
The West McArthur project, a Joint Venture with Cameco Corp. [TSX: CCO; NYSE: CCJ], is operated by CanAlaska that holds an estimated 88.86% ownership in the Project as a result of sole-funding exploration in 2025. The 2026 exploration program will be co-funded by Cameco and CanAlaska under the Joint Venture.
The 2026 winter drill program on the West McArthur Project is currently ongoing, with the company working to achieve an estimated 20 to 25 unconformity target intersections along the C10S corridor. The West McArthur drill program is focused on continued step-outs from the Pike Zone high-grade mineralization to evaluate for additional zones of uranium mineralization and continuation of the associated large hydrothermal alteration system. The Company expects to complete the winter portion of the 2026 exploration program in April.
All reported depths and intervals are drill hole depths and intervals, unless otherwise noted, and do not represent true thicknesses which have yet to be determined.
CanAlaska is a leading explorer of uranium in the Athabasca Basin of Saskatchewan, Canada. With a project generator model, the company has built a large portfolio of uranium projects in the Athabasca Basin. CanAlaska owns numerous uranium properties, totaling approximately 500,000 hectares, with clearly defined targets in the Athabasca Basin covering both basement and unconformity uranium deposit potential.
The company has recently concentrated on the West McArthur high-grade uranium expansion with targets in 2024 and 2025 leading to significant success at Pike Zone. Fully financed for the upcoming 2026 drill season, CanAlaska is focused on uranium deposit discovery and delineation in a safe and secure jurisdiction. The company’s team has a track record of discovery and projects that are located next to critical mine and mill infrastructure.
