SGS–Exterra mineral processing pact: cleaner flowsheets and what it means for operators
Reviewed by Joe Ashwell
First reported on International Mining – News
30 Second Briefing
SGS has entered a long-term strategic collaboration with Quebec-based Exterra Technologies to develop new mineral processing solutions aimed at strengthening Canada’s domestic critical mineral processing capacity. Announced at the PDAC 2026 Convention, the partnership targets lower environmental footprints in mineral production, signalling a push for cleaner process flowsheets and more efficient use of reagents and energy. For operators, the move points to future access to SGS‑validated Exterra technologies within Canadian testwork, pilot plants and commercial operations.
Technical Brief
- SGS will apply its testing, inspection and certification workflows to qualify Exterra’s mineral processing technologies.
- Exterra, based in Québec, contributes proprietary mining technology tailored to Canadian critical mineral orebodies.
- Joint work is expected to focus on flowsheet optimisation, reagent schemes and energy‑efficient unit operations.
- Environmental performance will be quantified through SGS measurement protocols rather than vendor self‑reporting.
- For other critical mineral jurisdictions, the model suggests pairing local tech developers with global TIC providers.
Our Take
SGS already features in our coverage via its Lakefield Metallurgical Centre of Excellence, and this Quebec-based collaboration suggests the company is extending its Canadian R&D footprint beyond Ontario into more region-specific processing solutions.
With over 2,000 tag-matched pieces under Projects/Product/Sustainability, collaborations like this in Quebec signal that service providers such as SGS are positioning themselves as key enablers of lower-impact processing rather than just testwork labs.
Quebec’s combination of hydropower and supportive provincial policies for low-carbon mining means any new mineral processing solutions developed there can become reference flowsheets for projects seeking ESG-linked financing in other jurisdictions.
