CanAlaska Uranium Ltd. (TSXV:

at the Pike Zone as part of the ongoing winter
exploration program on the West McArthur Joint Venture project (the "Project") in the eastern Athabasca
Basin. The main objectives of the 2024 drill program are continued expansion of the Pike Zone
discovery and along strike unconformity testing to the northeast and southwest. The West McArthur
project, a Joint Venture with Cameco Corporation, is operated by CanAlaska that holds an 83.35%
ownership in the Project (Figure 1). CanAlaska is sole-funding the 2024 West McArthur program, further
increasing its majority ownership in the Project.

over 2.4 metres, followed by several lower grade intervals
down hole (Table 1). The mineralization is characterized by massive to semi-massive, blebby,
disseminated, clay-hosted, and fracture-controlled uranium mineralization associated with yellow and
orange uranium secondaries at the contact between the Athabasca sandstone and the underlying
basement rocks (Figure 3). The mineralized intervals are hosted within a broad zone of intense clay and
chlorite alteration, resulting in complete replacement of the original rock fabric and textures.
Localized
intervals of lost core occur due to high rock friability.

The lower sandstone column of WMA082-4 is strongly bleached, limonite and clay altered, and contains
several multi-metre scale fault zones that consist of quartz dissolution, core loss related to broken and
blocky core, clay replacement, and clay-filled breccias extending over 80 metres above the uranium
mineralization. WMA082-4 is located approximately 30 metres along strike to the northeast of high-
grade uranium mineralization intersected in WMA082-2, which intersected 1.03% U

O

over 6.3 metres,
including a sub-interval of 2.82% U

O

over 1.9 metres (see News Release dated January 18, 2024).
The unconformity target at Pike Zone remains open in all directions around WMA082-4 (Figure 2).
CanAlaska CEO, Cory Belyk, comments,
"It is extremely rare to intersect uranium mineralization of this
grade and width anywhere in the world, including the Athabasca Basin. This is a significant outcome
for the West McArthur JV and CanAlaska shareholders. Since initial discovery in 2022, the
CanAlaska team has believed Pike Zone had the potential for Cigar- and McArthur River-like
uranium grades and thickness based on prior drilling results. The geologists have been laser focused
on determining the geological controls in a clear and methodical approach and the results of this
fantastic work are now achieving outcomes for our shareholders. Tier 1 uranium deposits always occur
as 'pearls on a string' and we have now found a pearl. We look forward to the remainder of the winter
program results from West McArthur in the backdrop of an eastern Athabasca region that requires a
tier 1 uranium deposit discovery to maintain its current production profile."

Geochemical Sampling Procedures and Use of Radiometric Equivalent Grades
All drill core samples from the 2024 program will be 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:NHO3:HClO4) and
partial digestion (HNO3:HCl), boron by fusion, and U

wt% assay by ICP-OES using higher grade
standards. Assay samples are chosen based on downhole probing radiometric equivalent uranium
grades and scintillometer (SPP2 or CT007-M) peaks. Assay sample intervals comprise 0.3 – 0.8 metre
continuous half-core split samples over the mineralized interval. Select density samples, comprising 0.1
metre continuous whole core samples that are subsequently assayed, may be taken within the
mineralized interval. One half of the split sample is retained and the other sent to the SRC for analysis.
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.
During active exploration programs drillholes are radiometrically logged using calibrated downhole
GeoVista NGRS and TGGS (Triple GM) gamma probes which collect continuous readings along the
length of the drillhole. Preliminary radiometric equivalent uranium grades ("eU
3
O
8
") are then calculated
from the downhole radiometric results. The probe is calibrated using an algorithm calculated from the
calibration of the probe at the Saskatchewan Research Council facility in Saskatoon. At extremely high
radiometric equivalent uranium grades, downhole gamma probes may become saturated, and a cap
may be applied to the grade. A 0.1% eU
3
O
8
cut-off with a maximum internal dilution of 1 metre is used
for compositing and reporting the data. A 1.0% or 2% eU
3
O
8
cut-off with a maximum internal dilution of 1
metre is used for compositing and reporting higher-grade sub-intervals. The equivalent uranium grades
are preliminary and are subsequently reported as definitive assay grades following sampling and
chemical analysis of the mineralized drill core. In the case where core recovery within a mineralized
intersection is poor, radiometric grades are considered to be more representative of the mineralized
intersection and may be reported in the place of assay grades. Radiometric equivalent probe results 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.
