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

announce that it has received assay results from the remaining drillholes completed during the 2022

program at the West McArthur project in the Athabasca Basin (Figure 1). The new geochemical assay

results indicate multiple high-grade intersections over a 12.6 metre wide zone in WMA072-3, highlighted

over 9.0 metres in WMA067 and provide a compelling target where the

mineralized structure intersects the unconformity. The West McArthur project, a Joint Venture with

Cameco Corporation, is operated by CanAlaska who currently holds a 79.3% ownership in the project.

The Company recently completed its drill program on the West McArthur project (see press release

dated September 29

th

, 2022). The majority of the drill program was focused on high-grade basement-

hosted uranium mineralization discovered in drillhole WMA067 (see press release dated July 15

th

,

2022). WMA067 is located 6 kilometres along strike on the C10 South (C10S) conductive corridor and

southwest of the Company's 42 Zone mineralization. As part of the discovery follow-up, eight drill tests

were completed on the same fence or along strike of the WMA067 discovery hole. High-grade uranium

mineralization has now been confirmed by assay in four drillholes in the discovery area at various

elevations throughout the 40 to 50 metre wide graphitic horizon (Figure 2).

Next Steps

The Company believes that it has successfully identified the orientation of the controlling structure for the

basement-hosted uranium mineralization as part of a larger fault system. The ideal target, where this

controlling-structure, the larger fault system, and the 40 to 50 metre wide graphitic horizon intersect the

unconformity, has not been drill-tested and remains a high-priority target for the next drilling program.

Unconformity targeting will focus both in the discovery fence area and along strike including where

WMA073 intersected a 40 metre wide strongly altered sandstone-hosted structure 200 metres above

the unconformity. The broad sandstone fault is associated with anomalous pathfinder elements including

uranium (1.17 ppm partial), copper (4.07 ppm partial), boron (1560 ppm total), and arsenic (3.46 ppm

partial). In addition, the assay results confirm the high-grade basement-hosted nature of the uranium

mineralization and suggest additional basement-hosted potential exists along strike of the discovery

fence (Figure 2).

A formal 2023 exploration program and budget for $10 million has been approved by the Joint Venture.

Mineralization Details

Multiple intervals of metre to sub-metre scale high-grade uranium mineralization were confirmed in

WMA067, WMA067-4, WMA070, and WMA072-3 (Table 1). The uranium mineralization is

characterized by massive to semi-massive, vein-controlled, and foliation-controlled pitchblende with

variable amounts of yellow to orange uranium secondaries (Figure 3). The main controlling structure is

hosted within a wide, faulted graphitic package that contains both foliation-parallel and cross-cutting

faults. The basement rocks around the mineralized intervals are altered with clay, chlorite, hematite, and

carbonate. To date, mineralization has been intersected between 20 and 100 metres vertically below the

unconformity.

CanAlaska CEO, Cory Belyk, comments,

"To intersect uranium mineralization up to 25% U

O

composite grade is a huge accomplishment for the team. The summer program clearly highlights the

potential of this new discovery to host very high-grade uranium and when coupled with the drill-

intersected structure and alteration in both the sandstone and basement, this new discovery truly

appears to be a potential tier 1 mineralizing event. This is exactly what the CanAlaska team felt the

project could deliver to shareholders and the next drilling program will focus on building upon this

initial success. The program and budget for 2023 has been doubled based on these results and in the

context of a continued strengthening of the uranium market fundamentals. We believe the timing

could not be more perfect to move this new discovery forward."

Geochemical Sampling Procedures

All drill core samples from the 2022 summer program were shipped to 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 U

wt% assay by ICP-OES using higher grade

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

uranium grades and scintillometer (SPP2 or CT007-M) peaks. Assay samples comprise 0.3 - 0.5 metre

continuous split-core samples over the mineralized interval. A 0.1% U

cut-off with a maximum internal

dilution of 1 metre is used for compositing and reporting the data. 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.
