CanAlaska Uranium Ltd.

(TSXV:

)

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

announce JV partner Denison Mines Corp. ("Denison") will be starting a 2,400 metre summer drilling

program at the Moon Lake South JV project (Figure 1). The project is operated by Denison and the

2021 drilling program is scheduled to begin around September 10

th

. CanAlaska holds a 25% ownership

in the project and will fund the Company's share of the 2021 exploration program.

In January 2016, Denison entered into an option agreement with CanAlaska to earn a 75% interest in the

Moon Lake South project. The project contains a 5 km long conductor corridor known as the CR-3

conductor (Figure 2), which is located approximately two kilometres west of the K-trend, host to the

Gryphon Deposit on Denison's adjacent Wheeler River property.

Denison drilled one diamond drillhole (MS-16-01) near the southern boundary of the Moon Lake South

project and confirmed the location of a new uranium target. The hole intersected an interval of fractured

and friable sandstone with uranium mineralization immediately at the unconformity (0.1% U

over 0.5

m). Associated with the uranium mineralization is alteration in the lower sandstone column consisting of

increased bleaching, desilicification, and dark grey pyrite. Additionally, in the basement of MS-16-01, a

0.8 metre-wide graphitic fault zone with evidence for reverse movement was intersected approximately

10 metres below the unconformity. The up-dip projection of this fault to the ideal target at the

unconformity is expected to be one of the priority targets for this drill program.

In 2017, as follow-up to the positive results in MS-16-01, Denison completed a Titan 24 DC-IP resistivity

survey over the conductor corridor and successfully mapped the extension of the trend for five kilometres

to the northeast. Denison further advanced the project in 2020, completing a SWML (Stepwise Moving

Loop) Electromagnetic (EM) survey that successfully outlined multiple untested EM targets with

associated resistivity anomalies, or 'bright-spots', along the CR-3 conductor trend. These EM bright-

spots are potentially indicative of basement alteration associated with uranium mineralizing processes

similar to the Arrow or Eagle Point uranium deposits. The 2021 summer drill program will evaluate four

of the highest priority targets identified from these surveys (Figure 2).

CanAlaska CEO, Cory Belyk, comments,

"The Moon Lake South project offers an intriguing set of

targets that have been developed over the last number of years by our new JV partner, Denison. This

program will drill-test priority targets along a mineralized corridor in the heart of the eastern Athabasca

Basin offering CanAlaska shareholders multiple opportunities for discovery. We look forward to

working with Denison to move this project forward."
