 Critical Resources lifts Mavis Lake footprint as drilling, metallurgy bolster lithium outlook


 Strategic Land Expansion

Critical Resources has expanded the Mavis Lake project by about 8,000 hectares — a ~25% increase — bringing the total landholding to more than 400 km². Proactiveinvestors UK+2MarketOpen Australia+2 This enlarged footprint adds several newly identified pegmatite trends, untested structural corridors, and fresh prospective targets. Proactiveinvestors UK+1 By consolidating such a large district-scale land position in Ontario’s premier lithium corridor, CRR now has greater flexibility and optionality for future discoveries and growth, positioning Mavis Lake as a major long-term asset in North America’s lithium supply landscape.

Drilling Progress & Resource Expansion

Since acquiring Mavis Lake in 2022, CRR has completed more than 58,000 metres of drilling across the property. MarketOpen Australia+1 The project already hosts a maiden JORC-compliant Inferred Mineral Resource of 8 million tonnes at 1.07% lithium oxide (Li₂O), alongside an exploration target of 18–29 Mt at 0.8–1.2% Li₂O. Proactiveinvestors UK+2Mining Weekly+2 Recent drill intercepts outside the existing resource envelope — such as 74.4 m at 1.18% Li₂O (including 32.9 m at 1.81%) and 50.2 m at 1.28% Li₂O — suggest the mineralised system is broader and more continuous than previously defined. Discovery Alert  Numerous spodumene-bearing pegmatites and over 30–31 new lithium-cesium-tantalum (LCT) pegmatite occurrences have been identified, underscoring the potential for significant resource growth as drilling continues.

 Metallurgical Success & Downstream Readiness

Feasibility-level metallurgical testwork at Mavis Lake has reportedly achieved near 100% spodumene recovery, along with a ~30% uplift in lithium grade, producing a clean, high-grade concentrate. Mining Weekly+1 That concentrate is deemed suitable for downstream conversion and battery manufacture, which bolsters the project’s credibility as a potential long-term supplier to the battery-metal supply chain. MarketOpen Australia+1 In addition, CRR holds an exclusive option to evaluate solid-state lithium-ion battery technology patents — possibly opening future value beyond just mining, into processing or licensing for advanced battery technologies. 

 Infrastructure, Jurisdiction & Community Support

Mavis Lake benefits from strong infrastructure: highway and rail access, clean hydroelectric power, and proximity to North American battery-manufacturing markets. Mining Weekly+1 The project sits in Ontario, a stable, mining-friendly jurisdiction with well-established regulatory frameworks and supportive policies for critical-minerals development. Mining Weekly+1 Further, CRR reports ongoing environmental baseline studies and positive engagement with Indigenous and local community stakeholders — strengthening its social license to operate. Proactiveinvestors UK+1 This combination of favourable geography, infrastructure and stakeholder support reduces execution risk and improves the feasibility of future development.

Timing, Market Outlook & Strategic Positioning

The expansion and technical progress at Mavis Lake come at a time when many analysts expect a rebound in lithium demand — driven by accelerating growth in electric vehicles and energy-storage technologies. Discovery Alert+1 CRR describes its recent land acquisition as a “counter-cyclical” move — securing high-potential ground at favourable valuations while the market is weaker. MarketOpen Australia+1 With its enlarged resource potential, clean concentrate, strong infrastructure, and optionality around battery-tech integration, Mavis Lake is increasingly positioned to play a key role in the North American lithium supply chain — possibly emerging as a competitive, low-cost feedstock source when demand rises.
