Saskatoon, Saskatchewan--(Newsfile Corp. - February 4, 2026) -
CanAlaska Uranium Ltd. (TSXV:
CVV)
(
OTCQX: CVVUF) (FSE:
DH7)
("
CanAlaska
" or the "
Company
") is pleased to announce the
start of the 2026 drill program on the Key Extension project (the "Project") in the southeastern Athabasca
Basin (Figure 2). The 2026 Key Extension winter program will focus on a series of high-priority target
areas identified from recent high-resolution airborne geophysical surveys and the review of historical
drilling programs on the project. One drill has been mobilized to the project site and drilling has now
begun (Figure 1). The Key Extension project is 100% CanAlaska-owned and is located approximately
15 km south of the past-producing Key Lake Mine and currently operating Key Lake Mill.

CanAlaska CEO, Cory Belyk, comments,
"I am very pleased with the start of this drilling program
located immediately south of the Key Lake Mine and Mill complex. This region has not been
extensively explored for basement-hosted uranium deposits and early results from CanAlaska's first
drill program in 2023 were very encouraging. Armed with new data, I look forward to results from drill
testing of these high priority targets. The uranium market continues to strengthen with uranium spot
price near US$100 per pound. The time is now for discovery of the next high-grade uranium deposit in
the southeastern Athabasca Basin."

2026 Key Extension Winter Exploration Program
The 2026 winter drill program on the Key Extension project will consist of one diamond drill operating to
complete an estimated 8 to 12 drillholes. The primary focus for the winter program will be on drill testing
a series of high-priority target areas identified based on the recent airborne geophysical surveys and the
review of historical drilling on the project (Figure 2). The targets are located within a series of long-linear
magnetic low corridors associated with conductivity high corridors that are interpreted to extend from the
Key Lake Mine and Mill complex through the Company's Key Extension and Nebula projects. The
magnetic lows with associated conductivity highs are interpreted to represent the graphitic
metasedimentary rocks of the lower Wollaston Domain in the highly prospective Wollaston-Mudjatik
transition zone. The Wollaston-Mudjatik transition zone is host to several unconformity-associated
uranium deposits in the Eastern Athabasca. Drill targets within the graphitic metasedimentary package
are focused on areas of interpreted structural complexity, where interpreted bends and breaks in the
conductive rocks may create the potential for transport and trap of hydrothermal uranium-bearing
mineralizing fluids.
The Company has identified four key target areas on the Key Extension project for the winter exploration
program:
Up-Ice of the Orchid Lake Boulder Field:
A series of drillholes are planned to test the conductive
stratigraphy along the western conductive trend up-ice of the historically reported radioactive Orchid
Lake boulder field. The targets are positioned immediately up-ice along the interpreted glacial ice
direction of the Orchid Lake boulder field (Figure 2).

Western Conductive Trend:
A series of drillholes are planned to test the long-linear conductive trend
along the western margin of the Key Extension project. This conductive trend, which represents over 10
kilometres of sparsely tested conductive target stratigraphy, parallels the highly prospective Wollaston-
Mudjatik transition zone. Along the trend, multiple conductor-parallel fault zones have been interpreted
from the high-resolution geophysical data. The interaction between these conductor-parallel and cross-
cutting fault zones represents high-priority exploration targets for basement-hosted uranium deposits.
The last drilling program on the Key Extension project, completed in 2023, successfully intersected
graphitic host rocks showing evidence of multiple post-Athabasca structural reactivation events,
hydrothermal alteration, and associated uranium enrichment along the western conductive trend (see
News Release dated August 29
th
, 2023).
Follow Up on Historical Drilling:
A series of drillholes are planned to test conductive stratigraphy along
strike of the KEY001, KEY002, and KEY003 drillholes. All three drillholes, completed by the Company in
2007, intersected a graphitic fault zone associated with clay, chlorite, and hematite alteration.
Importantly, KEY001 intersected 487.3 ppm uranium over 0.15 m from 184.7 m to 184.85 m.
Eastern Conductive Trend:
A series of drillholes are planned along the eastern conductive trend which
stretches over 5 kilometres along the eastern margin of the Key Extension project. This conductive trend
has not had historical drilling and represents a high-priority exploration target for the Company.

About CanAlaska Uranium
CanAlaska is a leading explorer of uranium in the Athabasca Basin of Saskatchewan, Canada. With a
project generator model, the Company has built a large portfolio of uranium projects in the Athabasca
Basin. CanAlaska owns numerous uranium properties, totaling approximately 500,000 hectares, with
clearly defined targets in the Athabasca Basin covering both basement and unconformity uranium
deposit potential. The Company has recently concentrated on the West McArthur high-grade uranium
expansion with targets in 2024 and 2025 leading to significant success at Pike Zone. Fully financed for
the upcoming 2026 drill season, CanAlaska is focused on uranium deposit discovery and delineation in
a safe and secure jurisdiction. The Company has the right team in place with a track record of discovery
and projects that are located next to critical mine and mill infrastructure.
The Company's head office is in Saskatoon, Saskatchewan, Canada with a satellite office in Vancouver,
