How Tersa Earth Supports Canada's Rare Earth Sovereignty
Last week, the Wall Street Journal reported on how China's tightening export controls are affecting access to critical minerals essential to Western defence manufacturing. China currently refines more than 90% of the world's rare earth elements, which has raised urgent questions about global supply chain security.
For Canada, this market reality represents a clear strategic opportunity. We already possess significant rare earth deposits, demonstrated processing capability, and strong partnerships with allies seeking supply diversification. TersaClean™ turns waste into opportunity—recovering rare earth elements from the millions of tonnes of tailings already produced across Canada's mining regions.
The foundation for rare earth sovereignty already exists. The question is how quickly we can build on it.
Canada's Rare Earth Supply Chain Is Already in Motion
Processing capability is already proven. The Saskatchewan Research Council Rare Earth Processing Facility operates as North America's first facility capable of producing separated rare earth elements. This isn't just a pilot project—it's a fully operational facility producing separated rare earth elements here in Canada.
Canada's rare earth potential extends far beyond geological surveys. The Thor Lake deposit in the Northwest Territories and Strange Lake on the Quebec-Labrador border represent world-class concentrations of heavy rare earth elements—the materials most critical to the development of advanced technologies.
Canada's institutional framework differentiates our approach to mineral supply relationships. Democratic governance, transparent regulatory processes, consistent environmental standards, and established defence partnerships create the predictable operating environment that long-term supply agreements require.
Activating Resources from Legacy Materials
New mine development requires decades of permitting and construction. Canada's existing tailings contain accessible concentrations of rare earth elements that can be activated through proven recovery technologies.
Using bioelectrochemical processes, Tersa Earth's TersaClean™ extracts critical minerals from tailings, treats acid mine drainage, and produces clean water. Rather than waiting for new mining projects and permits, this dual-purpose approach recovers valuable materials from existing waste streams while upholding and improving legacy environmental obligations.
In controlled applications, TersaClean™ achieved up to 99% metal recovery rates with complete acid neutralization within hours—performance metrics now being validated across diverse site conditions.
The World Economic Forum recognized Tersa Earth as a Top Innovator in Sustainable Mining, reflecting industry recognition for biological recovery systems as a viable alternative to traditional extraction methods. Rather than waiting for new mining projects, proven technologies can begin recovering materials from existing waste streams while addressing legacy environmental obligations.
Why Rare Earth Access Is a National Imperative
Defence and technology applications depend on specific rare earth elements for functionality. Modern fighter aircraft require hundreds of kilograms of rare earth materials for engines, avionics, and sensor systems. Precision-guided systems, electronic warfare platforms, and satellite communications rely on these materials for core operational capabilities.
Current global processing capacity is highly concentrated, with China handling over 90% of rare earth refining worldwide. This concentration creates supply vulnerabilities that recent market adjustments have demonstrated. The U.S. has responded with policies to diversify rare earth magnet supply chains by 2027.
Canada's position in the supply chain reconfiguration reflects natural advantages: established defence cooperation, geographic proximity to major manufacturing centres, and aligned strategic interests. Technologies that can rapidly activate domestic production from existing materials offer deployment timelines that new mining projects cannot match.
Partnership Frameworks for Scalable Deployment
Effective scaling requires coordinated engagement across mining operators, technology developers, government agencies, and Indigenous communities. Each stakeholder contributes essential capabilities: operational expertise, validated technologies, regulatory frameworks, and local stewardship knowledge.
The strongest opportunities emerge where multiple interests align. Legacy mine sites on traditional territories often present both environmental restoration priorities and economic development goals for Indigenous communities. Technologies that generate revenue while advancing ecosystem recovery naturally support Indigenous-led development approaches.
Canada's Critical Minerals Strategy provides national coordination for these multi-stakeholder efforts. The framework recognizes that mineral security requires innovation across extraction, processing, recovery, and recycling components of the value chain.
Moving from pilot validation to systematic deployment requires policy frameworks that support rapid scaling of proven technologies. Commercial demonstration facilities bridge the gap between technical validation and operational deployment, proving both performance and economic viability.
Building on Existing Strengths
Canada possesses complementary assets that position us for rare earth leadership: significant mineral resources, operational processing facilities, advanced recovery technologies, and established allied partnerships. These capabilities can be activated and scaled rather than developed from zero.
Tersa Earth contributes validated technology for transforming environmental liabilities into strategic resources. TersaClean™ represents one component of an expanding toolkit of biological and chemical recovery methods that can complement traditional mining while addressing legacy environmental obligations.
The path forward builds systematically on proven capabilities. Our mineral resources are surveyed and characterized. Our processing technologies are operational. Our partnerships are established and ready for expansion.
Canada's rare earth opportunity requires deployment of existing strengths rather than fundamental capability development. The materials have been extracted. The technologies are validated. The partnerships are aligned.
The next phase will require bold collaboration across sectors—to turn what's possible into what's operating at scale. Success depends on coordinated action that transforms demonstrated capabilities into operational capacity, serving both domestic strategic interests and allied supply security.
The opportunity is clear: transform the resources we've already extracted into the strategic foundation our future depends on.
