Mavis Lake Lithium Project: Strengthening Supply Chain Potential

Located in Ontario, Canada, the Mavis Lake Lithium Project has seen steady exploration progress. Drilling activities in the 2024 campaign have reinforced the presence of spodumene-bearing pegmatites beyond previously outlined zones, suggesting a broader mineralisation footprint than earlier projected. The main zone continues to deliver strong intersections, while the Tot Prospect, situated northeast of the main site, has added further depth and strike continuity.

These developments align Mavis Lake with the strategic interests of North America’s lithium supply ambitions. Continued technical efforts and engagement with local communities have positioned the project for forward momentum, with work ongoing to transition the asset towards future development. Environmental baseline studies and permitting steps are also underway, further anchoring the site’s longer-term roadmap.

Additionally, discoveries such as the Gullwing Pegmatite have provided further upside in exploration, supported by greenfield initiatives designed to uncover new mineralised zones.

Halls Peak Projects: Preparing for First Drilling Programs

In New South Wales, Critical Resources is gearing up for its maiden drilling programs across the Halls Peak Gold-Antimony Projects. Permits for a planned 24-hole reverse circulation campaign have been submitted for high-priority sites at Amoco and Mayview.

Surface sampling at Amoco has indicated the presence of high-grade gold and antimony, with new mineralised zones identified along an extended strike. Geological reviews support the system's classification as an orogenic gold-antimony structure, similar to other significant deposits in the region. Drill targeting is being refined based on geophysical analysis and geochemistry surveys, with further assay updates expected in the near future.

Corporate Activity: Strengthening Operational Foundation

On the corporate front, Critical Resources completed a successful capital raise during the quarter. These funds are allocated towards ongoing exploration and development activities across its key assets. The company’s financial positioning supports its immediate exploration plans while laying the groundwork for sustained advancement across both lithium and gold-antimony sectors.
