About West Mcarthur
The West McArthur project is located in the Eastern Athabasca Basin in Saskatchewan, between 6 and 30 kilometers west of the producing McArthur River mine (674.8 million pounds U₃O₈ at a grade of 16.99%).1Cameco’s Fox Lake deposit (inferred resource of 386.7 thousand tonnes at 7.99% U₃O₈ average grade for 68.1 million pounds uranium) is located immediately east of the property.2The West McArthur property was staked by CanAlaska in 2004 and optioned in April 2007 to Mitsubishi Development Pty Ltd., a subsidiary of Mitsubishi Corporation of Japan. In January 2016, CanAlaska Uranium Ltd. bought Mitsubishi’s 50% interest to hold 100% in the West McArthur property. Under an option agreement with Cameco signed in February 2016, drilling confirmed a new zone of high-grade uranium mineralization, the ’42 Zone’ at Grid 5. In late 2018 CanAlaska resumed Operatorship, with Cameco as a 30% JV partner. In 2022, CanAlaska announced the discovery of the Pike Zone on the West McArthur project.

CanAlaska Announces Assay Results from Winter Drill Program on West McArthur Project
Geochemical assay results from the 2026 winter drill program at the West McArthur Project in the southeastern Athabasca Basin, Saskatchewan, included 5.4 m at 1.48% U3O8 in WMA101-02 (including 0.5 m at 8.42%) and 0.5 m at 2.89% in WMA100-02; ten of twenty-four unconformity tests contained uranium mineralization, with the hydrothermal system now defined over 1.3 kilometres of strike.

Drilling has begun on the summer portion of the $15 million 2026 exploration program at the West McArthur joint venture project in the southeastern Athabasca Basin, Saskatchewan, using three diamond drills to achieve an estimated 20 to 25 unconformity target intersections. Work will step out southwest and northeast of the Pike Zone along the C10S corridor, with infill testing of gaps along the tre

A winter geophysical program on the West McArthur joint venture project in the eastern Athabasca Basin, Saskatchewan, identified over 20 kilometres of new conductor strike length along the Epp Lake corridor. The program comprised four survey lines totaling 78.0 km of Stepwise Moving Loop Time Domain Electromagnetics, mapping multiple strong northwest-dipping, southwest-trending stacked conductors

The winter drill program at the Pike Zone on the West McArthur joint venture project in the eastern Athabasca Basin, Saskatchewan, is complete, comprising 24 unconformity tests of which 10 contained uranium mineralization, with step outs 350 metres southwest and 350 metres northeast of prior drilling. The hydrothermal system along the C10S corridor is now defined over 1.3 kilometres strike length,

Ambassador Thomas Graham Jr. has retired from CanAlaska Uranium's board effective immediately, after almost two decades as a director since 2007, including serving as Chair from 2011 to 2024. He will retain the honorary designation of Chair Emeritus. CanAlaska explores uranium in Saskatchewan's Athabasca Basin, holding roughly 500,000 hectares, and states it is fully financed for the 2026 drill se

Drillhole WMA101-02 intersected 5.2 metres at 3.10% eU3O8 at the unconformity, plus 0.4 metres at 11.76%, about 250 metres northeast of the Pike Zone high-grade core on the West McArthur JV in the eastern Athabasca Basin, Saskatchewan. To the southwest, WMA100-02 extended mineralization roughly 50 metres along the C10S trend. Seven unconformity target intersections have been completed in 2026; thr

A $15 million exploration program has been approved for the West McArthur joint venture project in the southeastern Athabasca Basin, Saskatchewan, co-funded pro-rata by Cameco and CanAlaska, which holds an estimated 88.86% interest after sole-funding 2025 work. Three drills start in early January 2026, targeting step outs southwest and northeast of the Pike Zone along the C10S trend, where unconfo
