Vancouver, British Columbia--(Newsfile Corp. - August 12, 2021) -

CanAlaska Uranium Ltd. (TSXV:

CVV) (

)

("CanAlaska" or the "Company") is pleased to announce West

McArthur JV management board approval of a 5,000 metre summer drill program at the West McArthur

uranium project in the eastern Athabasca Basin. The project is operated by CanAlaska and this program

is scheduled to begin on 15 August. CanAlaska holds a 74.06% ownership in the project and will fully

fund the exploration in 2021 to increase its interest.

The West McArthur project "42 Zone" mineralization is located 12 kilometres west of Cameco and

Orano's McArthur River uranium mine, within the Grid 5 survey area. Drilling to date has discovered a

large sandstone alteration halo above high-grade uranium mineralization intercepted in replacement

zones at the unconformity. The first drilling of the season will continue to advance this discovery with the

next drill holes planned to intercept the southwestern extension of the main mineralized fault structure.

The northeastern extension of the 42 Zone fault is host to the nearby Fox Lake uranium deposit (68M

pounds U

@ 7.99%), which was discovered and announced by Cameco and Orano in 2016 (Figure

1). The southwestern extension of this fault has been recognized from field work and drill core relogging

by CanAlaska in 2020, and can be traced for at least three kilometres to the southwest of the 42 Zone

mineralization (Figure 2).

The extensive conductive corridor outlined by the geophysical imaging of Grid 5 is also shown in Figure

2, along with the key, wide-spaced, historical drillholes and intersections which allow interpretation of the

fault trace deep in the basement. These historical drill holes intersected hydrothermal alteration with

bleached zones and intervals of chlorite in the sandstone and basement. The drill intersections also

show re-activated semi-brittle fault zones that have coincident anomalous uranium values. Unlike the 42

Zone area, none of target areas A, B or C in Figure 2 have been drill-tested where the fault intersects the

unconformity. This will be the focus for drilling this season.

CanAlaska CEO, Cory Belyk, comments,

"Recognition of the controlling fault system for three

kilometres immediately southwest of the Company's 42 Zone discovery in the Grid 5 area was a key

outcome from the 2020 work program. The team is excited to start this program, which will test these

structures at the unconformity. Renewed interest in nuclear as a source of carbon-free energy

continues to grow and support the need for new uranium discoveries and investment at West

McArthur."

The Company has just completed its field program on the West Athabasca Diamond project. The

Company is awaiting drill permitting for the Strong nickel project and has just received its drill permit for

the Hunter nickel project, both near Thompson, Manitoba. The Company's Manibridge nickel project is

currently under a new third-party Option Agreement.
