Vancouver, British Columbia--(Newsfile Corp. - August 4, 2022) - CanAlaska Uranium Ltd. (TSXV: CVV) (OTCQX: CVVUF) (FSE: DH7N) ("CanAlaska or the "Company") is pleased to announce assay results from the winter 2022 drill program have confirmed the presence of high-grade nickel mineralization on the Manibridge project, located in the Thompson Nickel Belt, Manitoba (Table 1). The drill program successfully intersected high-grade nickel-sulphide mineralization in all six holes over a one-kilometre strike length within the shadow of the past-producing Manibridge mine that produced 1.3 million tonnes at 2.55% nickel and 0.27% copper from 1971 to 1977 (Figure 1).

Highlights from the drill program include:

MNB004, which intersected 0.92% Ni eq. over 32.95 m, from 150.45 m, which includes 1.24% Ni eq. over 11.45 m from 169.1 m;

MNB003, which intersected 0.81% Ni eq. over 13.5 m, from 337.5 m;

and MNB 006, which intersected 1.13% Ni eq. over 9.0 m, from 700.0 m, which includes 1.62% Ni eq. over 5 m from 701.0 m.

The sulphide mineralization, which contains nickel, copper, and cobalt is characterized by disseminated, massive, and net-textured sulphides associated with intense serpentinization alteration of the ultramafic host rocks. The program consisted of six diamond drill holes for a total of 2,350 metres. Drill hole collar locations are provided in Table 2 and Figure 2 shows the locations of the drill hole results on a long-section of mineralization.

Drill holes MNB001 and MNB003 both filled gaps in the mineralization model, defined by historic drill hole results, which indicates that the mineralization is still open along strike and at depth. Drill holes MNB002, MNB004, and MNB005 all intersected mineralization starting shallower than approximately 200 m from surface. Drill hole MNB006 successfully defined the continuation of high-grade mineralization beneath the old mine workings indicating that mineralization controls of the Manibridge system are continuous down to at least 700 m depth. The results of the 2022 winter drilling program indicate that the Manibridge system remains open in both the up- and down-dip directions as well as along strike, leaving multiple targets for future drill programs.

Metal Energy is the operator of Manibridge and owns 49% of the Project. Metal Energy has surpassed the work commitments required to earn 70% ownership, with a short-term objective to achieve 100% ownership of Manibridge from CanAlaska Uranium Ltd.

CanAlaska CEO, Cory Belyk, comments, "Assay results from the winter program confirm the Manibridge project is host to significant sulphide nickel mineralization in the shadow of a past-producing high-grade nickel mine. These results also highlight the discovery potential that exists within CanAlaska's nearby Resting and Halfway nickel projects that were project generated by the team on the same geological model as Manibridge. Class 1 nickel that is found in the Thompson Nickel Belt is a critical metal needed for electrification of the world as we move toward a clean energy utopia. CanAlaska's nickel portfolio provides its shareholders with exposure to discovery of this critical metal, and we are very pleased with results from this drilling program."

About the Manibridge Project

Manibridge encompasses 4,368 hectares within the world-class Thompson Nickel Belt. The Project is 20 kilometers southwest of Wabowden, which has significant infrastructure and capacity that has supported previous exploration programs and mine development, including year-round highway access via Highway 6.

Geochemical Sampling Procedures

Drill core samples 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-OES using total 4-acid digestion (HF:NHO3:HCl:HClO4). Assay samples comprise 0.35 to 1.0 m continuous split-core samples over nickel-sulphide mineralized intervals. The SRC is an ISO/IEC 17025/2005 and Standards Council of Canada certified analytical laboratory. Blanks, standard reference materials, and repeats were 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.

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.

Other News

The Company is actively advancing a new uranium discovery on its West McArthur uranium project in the eastern Athabasca Basin. As part of the summer program, the Company reported a 6.3 metre long interval of elevated radioactivity in the basement of WMA067, 100 m below the unconformity. WMA067 is located along a newly defined exploration trend, approximately 6 kilometres along strike to the southwest of the Company's 42 Zone mineralization. The summer drilling program is part of an approved $5 million program operated by CanAlaska, who currently holds a 77.13% ownership in the project.
