Critical Resources has expanded its Mavis Lake landholding by 25 per cent to more than 400 km² as it positions itself to capture rising global battery demand.
Critical Resources said its expanded landholding in Mavis Lake will enable it to take advantage of a promising lithium market rebound from 2026, driven by growing demand from electric vehicles and energy storage systems.
Located in northwestern Ontario, Canada, Mavis Lake is ideally placed to deliver scalable, lower-cost supply, supported by government funding, and surging demand for battery materials.
Critical Resources Managing Director Tim Wither said the opportunity to acquire additional claims secures a dominant land position for the company.
“This strategic decision underpins future growth potential across the Mavis Lake Lithium Project.
“Mavis Lake stands as one of Ontario’s significant lithium assets, distinguished by its scale, grade and access to world-class infrastructure, positioning the project to play a key role in North America’s lithium supply chain.”
Since acquiring the Mavis Lake lithium project in 2022, Critical Resources has undertaken numerous high-impact work programs to transform the project into one of Ontario’s most advanced lithium development opportunities.
Feasibility-level test work at Mavis Lake has shown near 100 per cent spodumene recovery and a 30 per cent increase in lithium grade, resulting in a high-grade spodumene concentrate with minimal impurities, ready for downstream conversion and battery manufacturing.
In addition, Critical Resources secured an exclusive option to undertake a research evaluation program with the South Dakota School of Mines and Technology on solid-state lithium-ion battery technologies.
This partnership enables the company to pursue vertical integration, leveraging its Mavis Lake resources as potential feedstock for advanced battery technologies. This agreement unlocks potential new value pathways from mine to market.
