MAVIS LAKE PROJECT DEVELOPMENT OPPORTUNITIES – LOCATION ADVANTAGE Strategically located in northwestern Ontario (Figure 1), Mavis Lake benefits from a unique combination of geological prospectivity, robust infrastructure, supportive government policy, and proximity to key North American markets. As the lithium sector enters a period of renewed optimism, Mavis Lake is ideally placed to deliver scalable, lower-cost supply, supported by government funding, streamlined permitting, and surging demand for battery materials.

The district-scale landholding now exceeds 400 km², with over 31 new LCT pegmatite discoveries underpinning ongoing resource growth potential. • Exceptional infrastructure: Immediate access to the Trans-Canada Highway, all-season roads, and national rail network enables efficient logistics and export pathways to US and international customers. Clean hydroelectric power and natural gas pipelines support low-emission, sustainable operations. • Government and community support: Federal and Provincial governments continue to prioritise critical minerals through funding and streamlined permitting. An Agreement-in-Principle with the Wabigoon Lake Ojibway Nation ensures the project aligns with community values and environmental stewardship. • Technical and environmental progress: Technical and baseline environmental studies are underway, leveraging infrastructure advantages to fast-track permitting and development. The project’s location allows for lower-emission operations and a commitment to minimising environmental impact. • Strategic positioning: Mavis Lake is ideally located and is positioned as a potential feedstock for the North American lithium supply chain. This enhances the project’s opportunities and readiness for the forecast lithium market rebound.
