Multiple Strong Conductors Associated with Uranium and Clay Pathfinders Highlight New

Over 20 Kilometres of New Drill-Ready Conductor Targets Identified
Saskatoon, Saskatchewan--(Newsfile Corp. - May 26, 2026) -
CanAlaska Uranium Ltd. (TSXV:
CVV)
(OTCQX: CVVUF) (FSE:
DH7)
("
CanAlaska
" or the "
Company
") is pleased to report the
results from the recently completed geophysical program on the West McArthur Joint Venture Project
(the "Project") in the eastern Athabasca Basin (Figure 1). During the winter exploration program, the
company completed a modern Stepwise Moving Loop Time Domain Electromagnetics (SWML-TDEM)
survey on the Epp Lake Corridor. The goal of the survey was to map a historical ZTEM conductivity
anomaly that is associated with a magnetic low corridor using high-resolution ground-based survey
methods. The survey identified multiple strong conductors stacked within a broad magnetic low corridor.
As a result of the winter geophysical survey and the historical drilling completed immediately to the north
of the survey area, the Company believes that these newly generated conductor targets represent a
significant opportunity for the discovery of high-grade unconformity uranium mineralization.

CanAlaska CEO, Cory Belyk, comments,
"The identification of 20 kilometres of previously unknown
and untested strong conductor targets on the West McArthur project in an area with nearby previously
drilled uranium and clay pathfinder anomalism is a great outcome for the joint venture. The Epp Lake
corridor has long been recognized as a strongly conductive graphitic-basement corridor in the eastern
Athabasca Basin. The resolution and extension of this corridor on the West McArthur project provides
another high priority set of drill-ready targets and discovery opportunity for future drill testing."
CanAlaska VP Exploration, Nathan Bridge, comments,
"The winter geophysical survey on the West
McArthur project highlighted multiple kilometres of stacked strong conductor anomalies along the
Epp Lake Corridor. Combined with the pathfinder anomalism in the historical drilling, the newly
defined geophysical targets represent a significant discovery opportunity. The team is currently
analyzing the new geophysical data with our historical knowledge to refine the best potential
exploration targets in this target area. In addition, the team is working diligently to prepare for our
upcoming summer drill program on the West McArthur project."

2026 West McArthur Winter Geophysical Program Results and Target Generation
The 2026 winter geophysical program on the West McArthur project consisted of four survey lines
totaling 78.0 km of SWML-TDEM surveying across the Epp Lake corridor. Historical work on this portion
of the West McArthur project identified a broad ZTEM conductivity corridor associated with a magnetic
low. The winter survey highlighted multiple strong northwest-dipping and southwest-trending conductors
stacked within a broad magnetic low (Figure 2). In total, over 20 kilometres of new conductor strike
length was identified during the survey. After the data collection, the Company completed Maxwell plate
modelling of the conductive features which shows a strong association between the magnetic low
corridor and the conductors. Generally, the conductors are strongest in the northern lines of the survey.

In Athabasca unconformity-associated uranium deposits, sandstone alteration halos are typically defined
by several key pathfinder elements including spectral clay identification of illite, dravite, and kaolinite,
and geochemical pathfinder enrichment consisting of various metals including uranium, arsenic, cobalt,
nickel, lead, and copper. Historically, in this portion of the project, 20 drillholes have been completed
testing various targets along the Epp Lake Corridor. Along the northern edge of the winter geophysical
survey area, several of these historical drillholes map a prominent lower sandstone illite anomaly that is
associated with a broader pervasive uranium pathfinder halo (Figure 3). In addition, northeast/southwest-
trending structural corridors in the Eastern Athabasca Basin are host to several prominent high-grade
unconformity-associated uranium deposits including McArthur River, Phoenix, and the Eagle Point
system

. As a result of the geophysical survey results and the pathfinder anomalies identified in the
nearby historical drilling, the Company believes that these newly-mapped conductor targets are typical
Athabasca Basin unconformity-associated uranium targets and represent a significant opportunity for the
discovery of high-grade unconformity-associated uranium mineralization.
The West McArthur project, a Joint Venture with Cameco Corporation, is operated by CanAlaska, which
holds an 88.89% ownership in the Project. The 2026 exploration program is being co-funded by
Cameco and CanAlaska under the Joint Venture.
