Winter Drill Programs Planned for Key Extension and Nebula Projects

Geophysics Programs Planned Across High Priority Exploration Projects

Saskatoon, Saskatchewan--(Newsfile Corp. - January 15, 2026) - CanAlaska Uranium Ltd. (TSXV: CVV) (OTCQX: CVVUF) (FSE: DH7) ("CanAlaska" or the "Company") is pleased to announce exploration plans for multiple projects in 2026 across its 500,000 hectare exploration portfolio focused on the eastern Athabasca Basin (Figure 1). Most notably, the Company will have drill programs starting in the coming weeks focused on the Key Extension and Nebula projects, located immediately south of the Key Lake Mine and Mill. The Key Extension and Nebula drill programs will focus on a series of high-priority exploration target areas that have been identified through recent airborne geophysical surveys. In addition, the Company is evaluating opportunities on multiple other projects, preparing them for future drill programs through the completion of ground and airborne geophysical programs. The Company also announced the start of the $15 million exploration program on the West McArthur Project (see News Release dated January 13^th, 2026). The Company is fully funded to complete its exploration programs in 2026.

2026 Key Extension and Nebula Exploration Programs

Winter drill programs are planned to start in Q1 of 2026 on the 100% CanAlaska-owned Key Extension and Nebula uranium projects located 15 km and 30 km to the south of the past-producing Key Lake Mine and currently operating Key Lake Mill in the southeastern Athabasca Basin. The planned programs will focus on a series of high-priority target areas identified from recent airborne geophysical surveys and the results of historical drilling.

Recently, the Company has assembled a large exploration land portfolio located 10 to 80 km south of the Key Lake Mine and Mill through low-cost staking and project acquisitions. Since assembling this large land portfolio, the Company has completed high-resolution helicopter-borne radiometrics and magnetics surveys over most of the land package. In addition, the Company has supplemented historical VTEM (Versatile Time Domain Electromagnetic) surveys in this area with modern VTEM surveys in areas that were lacking sufficient coverage. The goal of these high-resolution surveys was to identify and prioritize basement conductors, characterize lithological and alteration variations, refine areas of interest for ground prospecting, and map the structural setting of the project in support of future drill campaigns.

During the winter of 2026, the Company will be focused on first-pass exploration testing on a series of high-priority target areas identified based on the recent airborne geophysical surveys and the review of historical drilling (Figures 2 and 3). The surveys have outlined a series of long-linear magnetic low corridors associated with mapped conductivity highs that are interpreted to extend from the Key Lake Mine and Mill complex, through the Company's Key Extension project, and onto the Nebula project. 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 within the graphitic metasedimentary packages are focused on areas of interpreted structural complexity, where interpreted bends, breaks, and shifts in the conductive rocks may create and indicate the potential for transport and trap of hydrothermal uranium-bearing mineralizing fluids.

On the Key Extension project, the Company has identified three priority target areas, representing over ten kilometres of largely untested conductive corridor. One of these priority target areas is immediately up-ice along the interpreted glacial ice direction of the historically reported radioactive Orchid Lake boulder field (Figure 2). The last drilling program on the Key Extension project, completed in 2023, successfully intersected graphitic host rocks showing evidence of multiple post-Athabasca structural reactivation events, hydrothermal alteration, and associated uranium enrichment (see News Release dated August 29^th, 2023). On the Nebula project, the Company has identified two priority target areas, highlighted by over 13 km of untested target conductor corridor with a similar geological configuration to Cameco's Eagle Point Mine. In addition, the Karpinka Lake boulder train, with uranium grades up to 0.35%, is interpreted to be immediately down-ice of the highest priority target areas (Figure 3). The Company believes that historical drilling in the Karpinka Lake area has not successfully identified the source for this boulder train.

Additional 2026 Exploration Programs

The Company is preparing several additional discovery opportunities within its 500,000-hectare eastern Athabasca-focused land portfolio.

The Company is evaluating a ground-based electromagnetic survey on the Waterbury South project in the northeastern Athabasca Basin. The goal of the survey is to identify conductive corridors to generate targets for future drilling programs and follow up on historical mineralization and geochemical anomalism that was intersected during previous drill programs. The Waterbury South project is 100% CanAlaska-owned and is located just 10 km southeast of the Cigar Lake Mine.

The Company is evaluating a ground-based electromagnetic survey on the Cree East project in the eastern Athabasca Basin. The goal of the survey is to further refine historical geophysical targets that were identified during compilation work ahead of the 2025 exploration program. Assuming the survey is completed, the Company will evaluate and consider the potential for a summer drill program on the Cree East project. The Cree East project is located 35 km west-northwest of the Key Lake Mine and Mill complex and is 100% CanAlaska-owned. The Company recently received the Cree East project back fully unencumbered following the termination of an option agreement by Nexus Uranium. Under the option agreement, Nexus Uranium completed $3.4 million in new exploration work and defined numerous new priority exploration targets for follow-up drill testing (see News Release dated September 24^th, 2025).

On the Moon Lake South project, the Joint Venture has approved a geophysical exploration program for 2026. The program is expected to focus on the collection of high-resolution helicopter-borne VTEM and magnetics to map untested conductive corridors. The goal of the survey is to generate exploration drill targets to further advance the Moon Lake South project toward discovery. The Moon Lake South project is adjacent to Denison's Wheeler River property, host to the Gryphon and Phoenix deposits. The Moon Lake South project is a Joint Venture with Denison Mines Corp. ("Denison"), the operator. CanAlaska currently holds a 25% ownership in the project and will fund the Company's share of the 2026 exploration program.

The Company is also evaluating potential for summer drill programs on the Key Extension, Nebula, Voyager, and Enterprise projects. These summer drill programs would be focused on further testing of exploration targets along long linear magnetic low corridors associated with mapped conductivity highs from modern VTEM surveys. The Voyager and Enterprise projects are 100% CanAlaska-owned and are located between 20 and 30 km south of the Key Lake Mine and Mill.

CanAlaska CEO, Cory Belyk, comments, "The CanAlaska portfolio of projects is a world class opportunity for discovery of new uranium deposits. The team has been diligently and strategically assembling much of this portfolio over the past few years and now is the time to initiate exploration work on several priority targets. Importantly, it is our belief the portfolio of projects located south of the Key Lake Mine and Mill are vastly underexplored for basement-hosted unconformity-related uranium mineralization. The Nebula project targets outlined for 2026 represent some of the best early-stage Eagle Point uranium deposit style exploration discovery opportunities I have seen in my career. I look forward to the first drillholes into this exciting 16-kilometre-long target corridor."

Other News

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 building upon the past several exploration programs with 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 West McArthur project, a Joint Venture with Cameco Corporation ("Cameco"), 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 Company will be attending the Vancouver Resource Investment Conference ("VRIC") on January 25^th and 26^th in Vancouver, BC and will have representatives at booth #102.

The Company will also be attending the Investor Icebreaker: The Michael Gentile Mining Showcase Event on January 27^th in Vancouver, BC.
