CanAlaska Stakes Fourth Thompson Nickel Belt Project

Vancouver, British Columbia--(Newsfile Corp. - April 28, 2021) - CanAlaska Uranium Ltd. (TSXV: CVV) (OTCQB: CVVUF) (FSE: DH7N) ("CanAlaska" or the "Company") is pleased to announce that it has staked 12 new claim blocks covering 2,301 hectares (5752 acres) at Resting Lake in the southern Thompson Nickel Belt, near Wabowden, Manitoba. The claims cover and surround known mineralized zones as well as untested target horizons, south of the Wabowden nickel mines.

The new claims cover the majority of the Resting Lake structure, which is a 15-kilometre long synclinorium of Ospwagan Group sediments. The claims cover thirty ultramafic lenses within the prospective Pipe Formation, as shown on Figure 1. In the Thompson Nickel Belt the maximum potential for high-grade nickel mineralization resides in association of ultramafic and Pipe Formation rocks.

Nickel mineralization has previously been intersected in several drill holes which penetrated ultramafic horizons along the length of the structure, with several lenses of mineralization defined at either end of the structure. A reconnaissance drill hole also discovered nickel mineralization within the central part of the trend with one intersection grading 1.5 metres (4.9 ft) at 0.85% Ni.

All of the claims are easily accessible from the main Thompson highway, and benefit from adjacent rail and power infrastructure. The Bucko nickel mine and Bowden Lake nickel mine are located respectively 3km and 5km north of the Resting property, and along the same mineralized trend.

CanAlaska President Peter Dasler comments, "CanAlaska's team has identified multiple projects in Manitoba which would benefit from modern exploration and new drilling activity. There is strong worldwide demand for new sulphide nickel discoveries to back the ever- increasing demand for electric vehicle and storage batteries. The Thompson Nickel Belt in Manitoba is one of the world's largest nickel producing regions, and, with expiry of historical mining claims and long-term mining lease renewals, CanAlaska has been able to progressively acquire key exploration targets. We look forward to forming new Joint Ventures with interested exploration companies."
