Partner Sole-Funded Winter Program Marks First Drilling at Cree East in Over a Decade
Saskatoon, Saskatchewan--(Newsfile Corp. - April 29, 2025) -
CanAlaska Uranium Ltd. (TSXV: CVV)
(OTCQX: CVVUF) (FSE:
DH7)
("
CanAlaska
" or the "
Company
") is pleased to announce successful
completion of the winter drill program on the Cree East Project (the "Project") in the southeastern
Athabasca Basin (Figure 1). The program, which was the first on the Project in over a decade, focused
on a series of new high-priority targets identified based on the results of historical drilling and re-
interpreted geophysical surveys in Target Area B. During the program, the Company successfully tested
the targeted graphitic stratigraphy and intersected associated basement and sandstone hydrothermal
alteration, re-activated semi-brittle basement and sandstone faults, and elevated radiometry within the
graphitic fault zones.

CanAlaska CEO, Cory Belyk, comments,
"The first drilling in over a decade on this very large project
located just west of the Key Lake mill has substantially upgraded one of the main target areas by
intersecting related alteration, faults, and elevated radiometry. In many ways, the Cree East project is
revealing a potential deposit fingerprint that is commonly observed near significant uranium
mineralization in the eastern Athabasca Basin. Early results from this modest drilling program have
been highly encouraging and the CanAlaska team is looking forward to future drilling programs to
advance this project toward discovery."
2025 Cree East Winter Drill Program Complete
The 2025 winter drill program on the Cree East project is now complete. The program consisted of
seven diamond drill holes, five of which intersected the unconformity target horizon, for a total of 3,339
metres (Table 1; Figure 2). Two drillholes were lost due to technical issues. All of the drillholes were
completed in Target Area B due to encouraging results as the program progressed.

Drill program results are highlighted by CRE094 which intersected extensive hydrothermal alteration
consisting of strong bleaching, limonite, clay, and sooty pyrite in the lower sandstone column. In the
basement of CRE094, a broad graphitic pelite interval was intersected that contained multiple fault
intervals associated with bleaching, chlorite alteration, and localized elevated radiometry ranging from
10 - 40 cm in width and 100 - 300 cps. In addition, multiple drillholes contained broad sandstone fault
intervals characterized by broken, blocky, and faulted core with associated strong bleaching, clay, and
sooty pyrite alteration (Figure 3).

The 2025 drilling program successfully intersected graphitic host rocks showing evidence of post-
Athabasca structural reactivation events, hydrothermal alteration, and elevated radioactivity. In the lower
sandstone column, the Company also identified significant structure and hydrothermal alteration, now
defined over approximately 450 metres of strike length. These features are commonly associated with
basement-hosted uranium deposits. Results of the first drill program in over a decade on the Cree East
project indicate evidence of potential uranium-bearing hydrothermal fluids moving through Target Area
B.
Assay results for the drill holes completed during the winter 2025 exploration program are pending.
The Cree East Project is located approximately 35 kilometres west-northwest of the Key Lake Mine and
Mill complex. The Project is currently 100% owned by CanAlaska and work is being sole-funded by
Nexus Uranium Corp under an option earn-in agreement with the Company (see News Release Dated
March 19, 2024).
Drillhole Details
Drillhole CRE093 intersected a broad sandstone fault zone from 370.0 - 393.0 m, characterized by
strong bleaching and grey reduced alteration, which was followed by strongly bleached and silicified
sandstone. In the basement of CRE093, two major fault zones associated with strong alteration were
intersected. The first fault zone, from 469.8 to 475.4 m, was characterized by graphitic cohesive
cataclastic faulting. The second fault zone, characterized by a wide interval of strongly silicified breccia
from 548.5 to 574.0 m, overprints a strongly chloritized pelite with intermittent short intervals of preserved
cataclastic fabric. Strong bleaching, chlorite, and clay alteration extend throughout the basement and
were upgraded in intensity around the fault zones.
Drillhole CRE094 intersected a broad zone of reworked hematite, limonite, and strong bleaching in the
medial sandstone column associated with faulting from 353.0 to 389.0 m. In the basement of CRE094,
chloritized graphitic pelite was intersected from 485.0 to 526.0 m. Within the graphitic pelite, several
faulted intervals exhibit elevated radiometry with a peak of 300 CPS occurring in a
chlorite/carbonate/pyrite cohesive breccia at 505.1 m depth. Below the graphitic pelite, chloritized pelite
continues with several carbonate/pyrite/chlorite breccias containing elevated radiometry up to 250 CPS
and up to 25% visible chalcopyrite.
Drillhole CRE095 intersected a fault zone that straddles the unconformity. Within the sandstone, from
449.2 m to the unconformity at 452.0 m, the fault was a cohesive milled breccia consisting of large clasts
of quartz and sandstone suspended within a chlorite matrix. The fault extended to 454.7 m in the
basement and consisted of decimetre-scale intervals of friable cataclastic faulting with chlorite-rich
matrix and clasts of chlorite-altered basement.
Drillhole CRE096 is interpreted to have overshot the conductive target and intersected footwall
basement stratigraphy.
Drillhole CRE098 intersected a broad sandstone fault zone from 339.0 to the unconformity at 510.0 m.
The fault zone was characterized by broken, blocky, and faulted sandstone with re-activated clay gouge,
chaotic breccias, rotated bedding, and localized intervals of desilicification and core loss (Figure 3).
Throughout the fault zone, the sandstone was strongly bleached and silicified with increasing medium to
dark grey sooty pyrite alteration increasing in concentration with proximity to the unconformity. The
basement of CRE098 was characterized by a quartz breccia with clasts of quartz and clasts of fine
grained hematized and chloritized metasediments.
Drillholes CRE092 and CRE097 were lost before intersecting the target depth due to technical issues.

Geochemical Sampling Procedures and Scintillometer Readings
All drill core samples from the program, completed as HQ or NQ-sized core, were 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
3
O
8
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 intervals. With
all assay samples, 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.
The Company cautions that radioactivity is total gamma from drill core measured with a CT007-M
gamma-ray spectrometer/scintillometer in cps (counts per second). Measurements of total gamma cps
on drill core are an indication of the presence of radioactive materials (uranium, thorium, and/or
potassium), but may not directly correlate with uranium chemical assays. Total gamma cps readings are
preliminary and may not be used directly to quantify or qualify uranium concentrations of the rock
samples measured.
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.
