Colin Merril, Exterra Technologies

Chief of Staff

Exterra Technologies is a Québec-based mining technology company developing next-generation mineral processing solutions that enable producers to bring critical minerals to market faster, at lower cost, and with a reduced environmental footprint. Where it creates value, Exterra can also integrate carbon mineralization by converting CO₂ into stable mineral carbonates.

Its technology platform enables the circular regeneration and re-use of key chemical inputs, reducing reagent costs and volatility while lowering waste streams and tailings compared to conventional processing routes. Designed for global deployment, the platform is built on repeatable flowsheet development and a scalable technology licensing model.

Backed by a team with more than 150 cumulative years of experience in mine and process development, including 14 mines built and operated, Exterra is helping modernize mineral processing to strengthen the resilience of critical minerals supply chains.
