Saskatoon, Saskatchewan--(Newsfile Corp. - June 17, 2025) -
CanAlaska Uranium Ltd. (TSXV: CVV)
(OTCQX: CVVUF) (FSE:
DH7)
("
CanAlaska
" or the "
Company
") is pleased to announce the start of
the summer drill program as part of the $12.5 million 2025 exploration program on the West McArthur
Joint Venture project (the "Project") in the eastern Athabasca Basin. The 2025 West McArthur summer
program will focus on continued step outs from the Pike Zone to evaluate for additional zones of uranium
mineralization. Crews have mobilized to the project site and drilling has begun at Pike Zone. The West
McArthur project, a Joint Venture with Cameco Corporation, is operated by CanAlaska that holds an
85.97% ownership in the Project. CanAlaska is sole-funding the 2025 West McArthur program and will
further increase its majority ownership in the Project as a result.

CanAlaska CEO, Cory Belyk, comments,
"Following a very successful winter drilling program at Pike
Zone, the CanAlaska team is looking forward to getting back on the ground to advance this high-grade
uranium discovery. The main focus will be on extending the known unconformity-associated high-
grade uranium footprint in both directions along the unconformity target area. Late in the winter
program the team stepped out on the target to the west and successfully intersected significant
uranium mineralization similar to that observed immediately adjacent to the high-grade intersected in
other areas of Pike Zone. The unconformity target remains completely open for 1,000 metres to the
west and 600 metres to the east. With long-term contract uranium prices stabilized and a uranium spot
price market showing signs of movement upward, it is my firm belief we are on the cusp of another
uplift in the uranium market which will make delivery of our drilling results timely through the summer
and fall of 2025."
2025 West McArthur Summer Drill Program Plan
The 2025 summer drill program on the West McArthur project will have three drills working to achieve an
estimated 15 to 20 additional unconformity target intersections. The drill rigs will be focused on
continued step outs along strike to evaluate for additional zones of uranium mineralization and
extensions of the Pike Zone (Figure 2). To the west of the Pike Zone, the unconformity target area
remains untested for approximately 1,000 metres. To the east of the Pike Zone, the unconformity target
area remains untested for approximately 600 metres. In both directions, alteration and fault structures
were intersected in the lower sandstone column above the unconformity. Select infill targets within the
currently understood footprint of the Pike Zone may be completed during the summer program.

Results from recently completed drill programs indicate that the Pike Zone has a strike length of uranium
mineralization along the unconformity target area of approximately 250 metres that remains open in all
directions. Within that footprint, multiple drill fences outline a 130-metre-long high-grade pod of uranium
mineralization. During the recently completed winter drill program, significant uranium intersections were
returned, including WMA079-01 which intersected
8.3 metres at 24.82% eU

, including 5.5 metres
at 37.09% eU

, including 15.0
metres at 10.53% eU

(see
News Release
dated April 22
nd
, 2025). Importantly, the Company
advanced step out drilling along the C10S Corridor to the west of the Pike Zone, intersecting additional
high-grade uranium and extending the known footprint of unconformity-associated uranium mineralization
50 metres west of the previously understood mineralization footprint. The results from the recently
completed drill programs indicate that the strong hydrothermal mineralizing system remains open in both
directions along the C10S corridor and highlights the potential for additional mineralized pods along
strike.
The Company expects to complete the summer portion of the 2025 exploration program in September.
Assay results for the drill holes completed during the winter 2025 exploration program are pending.
Use of Radiometric Equivalent Grades
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 in-house algorithm calculated
from the calibration of the probe at the Saskatchewan Research Council facility in Saskatoon and from
the comparison of probe results against previously reported geochemical analyses. At extremely high
radiometric equivalent uranium grades, downhole gamma probes may become saturated, resulting in
the probe being overwhelmed, which in turn can create difficulties in accurately determining extremely
high-grade radiometric equivalent uranium grades, and a cap may be applied to the grade. 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 or non-existent, 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.
