Global testing leader SGS announced a strategic collaboration with Quebec-based Exterra Technologies to advance Canada's critical mineral processing capabilities while reducing environmental impacts in mining operations. The partnership was unveiled at the PDAC 2026 Convention in Toronto.
The collaboration follows Natural Resources Canada's announcement of a $5 million contribution agreement with Exterra through its critical minerals research, development and demonstration (CMRDD) program. Minister Tim Hodgson confirmed the funding will support Exterra's flagship Hub I pre-commercial project in Quebec, part of Canada's broader Critical Minerals Strategy.
Technology validation platform
Under the partnership, SGS will integrate Exterra's modular pilot plant and analytical systems across its metallurgical laboratories in Quebec City, Lakefield (Ontario), and Burnaby (British Columbia). This creates an independent validation platform for testing Exterra's on-site chemical regeneration technology, which aims to reduce reagent costs and environmental impacts compared to traditional single-use acids and bases.
Exterra plans to invest over $10 million in testing, research and pilot operations at SGS facilities to demonstrate the technology's commercial viability and global scalability.
"With SGS providing validation services, we are advancing a platform that aims to lower operating costs and reduces carbon footprint," said Olivier Dufresne, CEO and Co-founder of Exterra Technologies. "Together, we are building a cleaner, more competitive and more secure supply chain anchored in Quebec and scalable globally."
Independent third-party testing
SGS will provide rigorous third-party validation of Exterra's technology platform, offering the technical derisking needed to advance new mineral processing solutions toward commercial deployment. The testing company's involvement ensures independent verification of performance claims and optimization opportunities.
"The future of mining must address the industry's most pressing cost, recovery and ESG challenges," Stephen Mackie, senior director of metallurgy and consulting at SGS Natural Resources (North America), said. "We are excited about integrating Exterra's pilot operations within SGS facilities to strengthen independent validation and accelerate the deployment of next-generation mineral processing solutions."
Minister Hodgson emphasized the initiative's broader economic implications: "This collaboration between Exterra and SGS demonstrates how our government is unlocking made-in-Canada solutions that lower costs and reduce environmental impacts, all while building a more competitive, resilient economy for Canadians."
Strategic alignment
The partnership aligns with SGS's Strategy 27 corporate framework, which addresses industry megatrends including electrification, clean manufacturing, and supply chain security. It also supports the company's IMPACT NOW sustainability initiative focused on responsible natural resource development.
Exterra's technology platform enables circular regeneration of chemical inputs while reducing waste streams and tailings compared to conventional processing methods. The system can integrate carbon mineralization capabilities, converting CO₂ into stable mineral carbonates where commercially viable.
The Quebec-based company brings over 150 cumulative years of team experience in mine and process development, including 14 mines built and operated. The collaboration represents a significant step toward modernizing mineral processing to strengthen critical minerals supply chain resilience.
