CanAlaska Uranium Ltd. Announces Results from Key Extension Winter Drill Program CanAlaska Uranium Ltd. announced results from the winter drill program on its Key Extension project in the southeastern Athabasca Basin. The drill program focused on multiple high-priority target areas identified from recent airborne geophysical surveys and the results of historical drilling. During the program, the Company successfully confirmed the presence of strongly graphitic stratigraphy with re-activated semi-brittle basement fault zones containing associated hydrothermal alteration. The results from the drill program highlight the potential for discovery of basement-hosted uranium mineralization on the Project. The Key Extension project is 100% CanAlaska-owned and is located approximately 15 km southwest of the past-producing Key Lake Mine and current operating Key Lake Mill. The 2026 winter drill program on the Key Extension project consisted of five diamond drill holes for a total of 1,251 metres in two target areas. The program was focused on early-stage evaluation of a series of high-priority target areas identified based on the recent airborne geophysical surveys and the review of historical drilling. Results from the winter program on the Project are highlighted by the consistent intersection of graphitic stratigraphy containing re-activated graphitic fault zones with associated hydrothermal clay and chlorite alteration. During the drill program, two high-priority target areas were successfully tested: Follow Up on Historical Drilling: Three drillholes were completed to test conductive stratigraphy along strike of anomalous historical drillholes that contained a graphitic fault zone associated with clay, chlorite, and hematite alteration, and 487.3 ppm uranium over 0.15 m in drillhole KEY-001. KEY013, KEY014, and KEY015 successfully extended the strike length of the graphitic corridor in the target area. KEY014, which was the deepest test of the graphitic corridor, displayed the strongest chlorite and clay alteration associated with re-activated fault structures at depth. These results suggest that additional drilling in this target area should focus on testing deeper below surface on the conductive corridor for increasing hydrothermal alteration and the potential for basement-hosted uranium mineralization. Up-Ice of the Orchid Lake Radioactive Boulder Field: Two drillholes were completed to test a series of conductive targets up-ice along the interpreted glacial ice direction of the historically reported Orchid Lake radioactive boulder field. KEY017 and KEY018 successfully intersected graphitic stratigraphy containing semi-brittle fault zones associated with localized chlorite and clay alteration. Results from the drillholes in this target area did not explain the source of the Orchid Lake radioactive boulder field. Additional drilling should be completed both closer to, and further along strike of, the conductive stratigraphy to continue to evaluate for the source of the Orchid Lake radioactive boulder field. Due to seasonal access challenges, the Company was unable to test several additional high-priority target areas on the Project including the Western Conductive Trend, the Eastern Conductive Trend, and drill targets more proximal to the Orchid Lake radioactive boulder field. The high-priority target areas on the Key Extension project remain focused on a series of long-linear magnetic low corridors associated with conductivity high corridors that are interpreted to extend from the Key Lake Mine and Mill complex area through the Company's Key Extension and Nebula projects. The magnetic lows with associated conductivity highs are interpreted to represent the graphitic metasedimentary rocks of the lower Wollaston Domain in the highly prospective Wollaston-Mudjatik transition zone. Drill targets on the Key Extension project within the graphitic metasedimentary package are focused on areas of interpreted structural complexity, where interpreted bends and breaks in the conductive rocks may create the potential for transport and trap of hydrothermal uranium-bearing mineralizing fluids. The Company is currently in the process of planning a helicopter-supported fall drill program on the Key Extension project. Priority targets for the planned program will be those that were inaccessible due to seasonal access challenges, including the Western Conductive Trend, the Eastern Conductive Trend, and drill targets more proximal to the Orchid Lake radioactive boulder field. Geochemical assay results from the winter drill program on the Key Extension project are pending. All assay drill core samples from the program, completed as NQ-sized core, were shipped to the Saskatchewan Research Council Geoanalytical Laboratories (SRC) in Saskatoon, Saskatchewan in secure containment for preparation, processing, and multi-element analysis by ICP-MS and ICP-OES using total (HF:NHO3:HClO4) and partial digestion (HNO3:HCl), boron by fusion, and U3O8 wt% assay by ICP-OES using higher grade standards. Assay samples are chosen based on downhole probing radiometric equivalent uranium grades and scintillometer (SPP2 or CT007-M) peaks. Assay sample intervals comprise 0.3 – 0.8 metre continuous half-core split samples over the mineralized intervals. With all assay samples, one half of the split sample is retained and the other sent to the SRC for analysis. The SRC is an ISO/IEC 17025/2005 and Standards Council of Canada certified analytical laboratory. Blanks, standard reference materials, and repeats are inserted into the sample stream at regular intervals by CanAlaska and the SRC in accordance with CanAlaska's quality assurance/quality control (QA/QC) procedures. Geochemical assay data are subject to verification procedures by qualified persons employed by CanAlaska prior to disclosure. The historical results contained within this news release have been captured from the Saskatchewan Mineral Assessment Database (SMAD) as available and may be incomplete or subject to minor location inaccuracies. Management cautions that historical results collected and reported by past operators unrelated to CanAlaska have not been verified nor confirmed by a Qualified Person; however, the historical results form a scientific basis for ongoing work on the subject projects. Any historical rock /boulder samples are selective samples by nature and as such are not necessarily representative of the mineralization hosted across the property. 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. Announcement • Jun 10
CanAlaska Uranium Begins Summer Drill Program At West Mcarthur Joint Venture CanAlaska Uranium Ltd. has announced the start of the summer drill program as part of the $15 million 2026 exploration program on the West McArthur Joint Venture Project in the southeastern Athabasca Basin. The 2026 West McArthur summer program will focus on continued step outs to the southwest and northeast of the currently defined high-grade mineralized footprint of the Pike Zone to evaluate for additional zones of high-grade uranium mineralization and continuation of the associated large hydrothermal alteration system. The West McArthur project, a Joint Venture with Cameco Corporation, is operated by CanAlaska which holds an 88.89% ownership in the Project. The 2026 exploration program is being co-funded by Cameco and CanAlaska under the Joint Venture. The 2026 summer drill program on the West McArthur project will consist of three diamond drills operating to achieve an estimated 20 to 25 unconformity target intersections. The summer drill program will continue to build on results from the successful winter exploration program where the Company stepped out 350 metres southwest and 350 metres northeast from previous drilling, intersecting continued strong alteration, structure, graphitic host stratigraphy, and multiple drill fences with unconformity-associated and basement-hosted uranium mineralization. The primary focus for the summer program will be continued systematic testing to evaluate the C10S corridor for additional pods of high-grade uranium mineralization. Target areas are concentrated both to the southwest and northeast of the high-grade Pike Zone core. The drill program will focus on additional step-outs along the trend and infill testing of larger gaps along the trend where strong hydrothermal alteration and lower-grade uranium mineralization indicate the potential for additional pods. The Company will continue to utilize the recent geophysical survey results for targeting, which indicate interpreted structural complexity with sharp changes in orientation of the main conductor trend in the immediate four kilometres of strike length around the Pike Zone. Results from recent drill programs on the Project have defined the hydrothermal system associated with the unconformity target area along the C10S corridor over 1.3 kilometres strike length, with over one kilometre strike length containing uranium mineralization. The target corridor remains sparsely tested over 530 metres strike length to the northeast and 630 metres strike length to the southwest from the 140-metre-long high-grade core of the Pike Zone. The results from recent drill programs show similar continued hydrothermal alteration intensity, styles, and types as those that are observed in direct association with the Pike Zone near the most significant high-grade intersections drilled to date. The Company believes that the recent positive drill program results coupled with the already proven uranium endowment of the C10 and C10S corridors highlights the significant potential for the discovery of additional unconformity-related high-grade zones of uranium mineralization. As a result, continued systematic evaluation for additional high-grade pods of unconformity-associated uranium mineralization in both directions along the C10S corridor is the main priority for the summer drill program. The Company expects to complete the summer portion of the 2026 exploration program in September. The geochemical assay results from the winter portion of the 2026 exploration program are pending.
