CanAlaska Announces Mobilization To Moon

Lake South For Drill Program

Program is Focused on Testing Extensions of New High-Grade Uranium Mineralization

Two Drill Program Continues at Pike Zone Discovery on West McArthur JV Project

Vancouver, British Columbia--(Newsfile Corp. - September 19, 2023) -

CanAlaska Uranium Ltd.

(TSXV:

OTCQX:

(FSE:

)

("CanAlaska" or the "Company") is pleased to

announce mobilization of the crews for a supplemental exploration drilling program by the Moon Lake

South Joint Venture ("MLSJV") at its Moon Lake South project (the "Project"). The Company recently

reported the MLSJV doubled the 2023 exploration budget with the addition of this supplemental drill

program focussed on testing for extensions of high-grade uranium mineralization intersected during the

winter program. Geochemical assay results from the winter drill program's MS-23-10A returned a high-

grade intersection of

2.46% U

over 8.0 metres, including 3.71% U

. The

MLSJV is 75%-owned and operated by Denison Mines Corp. ("Denison"), and CanAlaska holds a 25%

ownership (Figure 1). CanAlaska is funding the Company's share of the 2023 exploration programs.

The supplemental drill program is expected to consist of 4 to 8 drillholes for a total of up to 4,400 metres.

The program will focus on testing the northeast strike extension of the high-grade perched uranium

mineralization intersected in MS-23-10A. Drill hole MS-23-10A intersected

, approximately 30 metres above the unconformity

(Figure 2). The mineralization in MS-23-10A represents the highest-grade mineralized intersection

drilled to date along the CR-3 conductor on the Moon Lake South project. Given the limited number of

drill holes completed on the project to date, the mineralization discovered in MS-23-10A remains open in

multiple directions. The winter exploration program results, combined with previous drill programs, have

confirmed uranium mineralization in multiple zones over a strike length of four kilometres along the CR-3

target corridor. The high-grade mineralization remains open along strike for at least 1.2 kilometres to the

northeast, representing a high priority target corridor for the supplemental drill program.

CanAlaska CEO, Cory Belyk, comments,

"The CanAlaska team is very excited to be back drilling this

high-grade mineralization with our partner, Denison. Mineralization of this magnitude located well

above the unconformity is very rare without significant root zones of mineralization at the unconformity

contact below. This contact will be a priority target for follow-up as part of this program. The uranium

price continues to climb to new recent highs making the timing of this supplemental drilling program a

significant opportunity for CanAlaska's shareholders to benefit from this discovery."

Other News

The Company is currently drilling at its West McArthur uranium project in the Eastern

Athabasca Basin.

The primary objective of the drill program is advancing the Pike Zone discovery,

including continued focus on expansion of basement-hosted high-grade uranium mineralization as well

as continued unconformity target testing.
