CanAlaska Expands Uranium Exploration at West McArthur, Identifies New Targets
Saskatoon, Saskatchewan – CanAlaska Uranium Ltd. (CVV.V), a key player in Athabasca Basin uranium exploration, announced promising results from its 2025 ground-based geophysical survey at the West McArthur Joint Venture project. The findings significantly extend the C10/C10S conductive corridor, a prime target for high-grade uranium deposits, to approximately 16 kilometers. This extension, identified using the same exploration methodology that led to the Pike Zone discovery, reinforces the project’s potential.
The survey, encompassing 193 line-kilometers across 55 loops, successfully imaged multiple stacked conductors, revealing new targets southwest of the Pike Zone and refining existing drill targets. CanAlaska, holding an 85.97% ownership stake, is fully funding the 2025 program, thereby increasing its majority interest in this highly prospective project.
Bolstering their commitment, CanAlaska has approved a $15 million exploration budget for 2026, a 20% increase over the 2025 expenditure. This robust budget will fuel an early January 2026 winter drill program, utilizing three drill rigs to aggressively pursue the newly identified uranium targets.
“Results from the 2025 geophysics program highlight the growing target inventory along the C10S corridor on the West McArthur Joint Venture project. Furthermore, it is very encouraging to see the detailed structure interpretation to the immediate southwest of Pike Zone from the CanAlaska team that coincides with what was observed and reported from the 2025 summer drilling program. With the 2026 West McArthur program now approved and fully funded, I look forward to the drills turning again in early January and building upon the success of the 2025 exploration program,” Cory Belyk, CEO of CanAlaska, commented.
Geophysical Survey Reveals Untapped Potential
The Stepwise Moving Loop Time Domain Electromagnetic survey (SWML-TDEM) played a crucial role in delineating multiple conductor plates aligned with the C10S conductive trend. By integrating the new data with the results from the 2022 SWML-TDEM survey, CanAlaska has created a comprehensive map of the C10/C10S conductive corridor, allowing for more precise drillhole targeting. Of particular interest is the improved definition of a historical parallel conductive trend near the southwest corner of the project.
The C10/C10S conductive corridor exhibits stacked conductor responses, indicating a complex geological structure. Shifts in the conductor’s orientation, particularly around the Pike Zone, suggest structural duplication, potentially creating open spaces for uranium-bearing fluids to migrate and accumulate. This structural complexity mirrors the conditions found within the Pike Zone itself, where intense sandstone and basement alteration are associated with high-grade uranium mineralization.
Strategic Significance and Future Exploration
The West McArthur project’s location within the Athabasca Basin, a globally significant uranium mining district, amplifies its strategic importance. The C10/C10S conductive corridor hosts several uranium deposits and zones, including CanAlaska’s Pike Zone and 42 Zone discoveries, as well as Cameco and Orano’s high-grade Fox Lake uranium deposit. Given the limited drill testing outside the Pike Zone and 42 Zone areas, CanAlaska believes the 16-kilometer C10/C10S conductive corridor holds substantial potential for the discovery of additional high-grade uranium zones.
While the extended corridor presents significant opportunities, approximately 10 kilometers of the C10S basement conductor remain untested to the southwest, highlighting the need for continued exploration. The company’s recent summer drilling program intersected unconformity-associated uranium mineralization with strong alteration, structure, and graphitic host stratigraphy southwest of the Pike Zone, further emphasizing the area’s potential.
Recent Developments
The company announced that both Bayridge Resources and Paradigm Gold Corporation have elected to terminate their options to acquire interests in the Constellation and various Manitoba nickel properties, respectively. This refocuses CanAlaska’s efforts on its core uranium assets in the Athabasca Basin.

What did CanAlaska announce about the West McArthur C10S corridor on November 25, 2025 (CVVUF)?
CanAlaska reported the C10/C10S conductive corridor was imaged to approximately 16 kilometres using 2025 SWML-TDEM data, extending the strike from the Pike Zone.
How large is CanAlaska’s 2026 West McArthur exploration budget (CVVUF) and how does it compare to 2025?
A $15 million 2026 budget was approved, representing a 20% increase over the 2025 program.
When will CanAlaska start drilling at West McArthur and how many rigs will be used (CVVUF)?
The 2026 drill program is scheduled to start early January 2026 and will deploy three drill rigs for the winter portion.
What geophysical coverage did the 2025 SWML-TDEM survey provide at West McArthur (CVVUF)?
The survey covered about 193 line-kilometres across 55 loops, with plate modelling and 3D inversion to refine targets.
How much of the C10S corridor remains untested by drilling at West McArthur (CVVUF)?
The release states roughly 10 kilometres of basement conductor along the C10S corridor toward the southwest remain untested by drilling.
Did any partners terminate option agreements related to CanAlaska properties (CVVUF)?
Yes; Bayridge terminated its option on Constellation property and Paradigm terminated options on several Manitoba nickel properties, leaving no earned interest.
