CanAlaska Discovers Significant New Uranium

Zone at West McArthur

Wide Zone of Basement-Hosted Uranium Mineralization 6 Km South of 42 Zone

Faulted Graphitic Conductor with Mineralization 100 m Below Unconformity

Extensive Summer Drill Program Continuing on West McArthur Project

Vancouver, British Columbia--(Newsfile Corp. - July 15, 2022) -

CanAlaska Uranium Ltd. (TSXV:

CVV

) (OTCQB:

CVVUF

) (FSE:

DH7N

)

("CanAlaska" or the "Company") is pleased to announce it has

intersected a wide interval of basement-hosted uranium mineralization along a newly defined exploration

trend on the West McArthur project (Figure 1).

Drill hole WMA067 was the second regional test of the current summer drilling program. The drill hole

intersected a broad,

6.3 metre-long interval of elevated radioactivity

(> 300 counts per second (cps)

on a handheld CT007-M scintillometer). The broad interval includes several metre- to sub-metre-long

intervals of moderate to strong radioactivity, one of which is 3.5 metres long (> 5,000 cps on the CT007-

M). WMA067 is located 6 kilometres along strike to the southwest of the Company's 42 Zone

mineralization (Figure 2). The uranium mineralization is characterized by pitchblende and yellow uranium

secondaries with associated clay and hematite alteration in faulted basement rocks approximately 100

metres below the unconformity.

CanAlaska CEO, Cory Belyk, comments,

"The CanAlaska team has delivered a new uranium

intersection in a new area of the West McArthur project with its second drill hole of the summer

program. With multiple recently announced build-outs of small modular reactors ("SMRs") in the

Canadian market alone, the need for more uranium discoveries that can lead to increased production

has never been more apparent. The West McArthur project, strategically located next to critical mine

and mill infrastructure in the eastern Athabasca Basin, continues to respond positively to targets

generated by the geological team providing additional opportunities for discovery for our

shareholders. This is an important and exciting result early in the 2022 drilling program."

Drill hole WMA067 was designed to test a strong conductor anomaly identified during the 2022 winter

geophysical program. The drillhole penetrated 52.8 metres of overburden followed by Athabasca

sandstone to 803.8 metres. The lower 80 metres of the sandstone column is strongly bleached with

several fault zones containing limonite alteration and de-silicification. Two major metre-scale fault zones

in the basal sandstone, the lowermost of which straddles the unconformity, are associated with strong

clay, limonite, and strongly de-silicified core resulting in approximately 30% core recovery. The

basement of WMA067 consists of a wide package of graphitic and non-graphitic pelitic metasediments,

explaining the conductive response. In the immediate 30 m below the unconformity, the metasedimentary

package is overprinted by strong clay, chlorite, and hematite alteration associated with multiple fault

zones that contain clay gouge, broken core, and cataclastic breccias. The remainder of the basement

intersection is variably clay and chlorite-altered, increasing in intensity around intervals of increased

fracturing as damage zones to graphitic fault zones. The intensity of the basement alteration increases

with depth, leading up to the basement-hosted uranium mineralization. The mineralization is structurally-

controlled within a broad graphitic shear zone that hosts several re-activated faults. The mineralization,

starting at 906.3 m, is characterized by massive to semi-massive, vein-controlled, and disseminated

pitchblende and yellow uranium secondaries that are associated with bleaching, clay, and hematite

alteration (Figure 3). Core recovery throughout the basement intersection is 100%. The radioactive

intervals are summarized in Table 1.

Radioactivity is total gamma from drill core measured with a CT007-M gamma-ray spectrometer/scintillometer in cps (counts per second).

.

Measurements of total gamma cps on drill core are an indication of the presence of radioactive materials (uranium, thorium, and/or

potassium), but may not directly correlate with uranium chemical assays. Total gamma cps readings are preliminary and may not be used

directly to quantify or qualify uranium concentrations of the rock samples measured.

.

The Company considers all CT007-M readings greater than 300 cps to constitute elevated radioactivity, with background radioactivity

measuring between 50 to 125 cps.

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.

Future Plans

The Company is continuing its drilling program on the West McArthur uranium project. The program is

part of the approved $5 million 2022 exploration program. The West McArthur drilling program is

focused on continued expansion of the 42 Zone mineralization, exploration within the 1.8 km 42 Zone

extension target area, and testing of multiple new targets generated during the winter geophysical

program. The West McArthur project is operated by CanAlaska, who currently holds a 77.12%

ownership in the project.

As drill holes are completed, drill core samples are 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:NHO

wt% assay by ICP-OES using higher grade

standards. Radiometric assay samples are chosen based on downhole probing radiometric equivalent

uranium grades and scintillometer (CT007-M) peaks and comprise 0.3 to 0.8 m continuous split-core

samples over mineralized intervals. 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.

Other News

On the Company's Manibridge project, its partner Metal Energy is actively completing the phase two

summer drill program. The drilling is focused within the shadow of the past-producing Manibridge Nickel

Mine that produced 1.3 million tonnes at an average grade of 2.55% nickel and 0.27% copper from

1971 to 1977, in the Thompson Nickel Belt, Manitoba.
