Vancouver, British Columbia--(Newsfile Corp. - September 15, 2021) -

CanAlaska Uranium Ltd.

(TSXV:

CVV

) (OTCQB:

CVVUF) (

FSE:

DH7N

)

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

announce it has entered into a Letter of Intent ("LOI") with Durama Enterprises Limited ("Durama"), a

private company, to allow CanAlaska to earn up to 100% interest in Durama's 100%-owned 17,665

hectare Key Extension Project in the Athabasca Basin region, Saskatchewan, Canada (the "Project")

(Figure 1).

The Company may earn up to a 100% interest in the Project by undertaking work and payments in a

single stage over a four year period. In order to meet conditions of the four year earn-in, CanAlaska will

make total cash payments of $50,000, issue 300,000 common shares in the Company subject to

approval of the TSX Venture Exchange, and complete work totalling $850,000 as outlined in Table 1. In

addition, a 1.5% Net Smelter Return (NSR) royalty will be granted to Durama to complete the earn-in.

CanAlaska will retain the right to bring in third-party funding to complete the option requirements.

The Key Extension Project lands cover the highly prospective Wollaston-Mudjatik transition zone (WMTZ)

in the Southeastern Athabasca Basin (Figure 2). The Project lands have been explored with historical

regional and project scale ground and airborne geophysical surveys, with additional focused prospecting

programs targeting lake sediment and boulder anomalies. The regional geophysical surveys map linear

magnetic low features with corresponding electromagnetic (EM) conductors on the eastern-most claim

of the Project, typical of the Lower Wollaston Domain. On the Western claims, the conductors are

generally shorter strike length discontinuous features, typical of the Mudjatik Domain. Focused airborne

magnetics and VTEM (Versatile Time Domain Electromagnetic) surveys were completed by past

operators of the Project in the early 2000's, outlining a prominent 10 kilometre long northeast-trending

conductor corridor that is coincident with a magnetic lineament that trends toward the historically

producing Key Lake uranium deposits, Deilmann and Gaertner (Figure 2), and swings to the south along

the Wollaston-Mudjatik boundary.

Despite the prolonged regional exploration and Key Lake deposit discoveries in the area, the Project

lands have only undergone minimal drill testing in the late 1970's consisting of shallow regional tests of

conductors. Extensive drilling has been completed in and around the Key Lake deposits and associated

showings, located approximately 10 km from the northeastern project boundary. The Key Lake deposits

consist of a series of east-northeast striking pods of unconformity associated uranium mineralization,

which have historically produced over 150 million lbs U

from the Gaertner and Deilmann open pits.

The deposit-controlling Key Lake structure and stratigraphy are interpreted to trend onto the Project

lands based on the magnetic lineaments and conductor patterns in the geophysical data.

CanAlaska CEO, Cory Belyk, comments,

"CanAlaska is very pleased to acquire this option on the Key

Extension Project. An opportunity to acquire a vastly under-explored 10 km section of the Key Lake

structure and stratigraphy ahead of a sustained uranium market up-turn which we believe is coming is

a significant achievement for our shareholders. Newly-defined exploration criteria and methods for

discovery of basement-hosted Athabasca Basin uranium deposits has yet to be applied on this

project. The CanAlaska team is looking forward to the next phase of exploration on Key Extension."
