Mining doesn't have a resource problem. It has a technology problem. The world has more than enough known mineral deposits to meet its needs. What's missing is the technology to turn those resources into economically and environmentally viable operations.
who we are
Exterra Technologies is a team of mining veterans with a combined experience of over 125+ years across 14 mine development projects around the world. We are focused on commercializing the first significant breakthrough in mineral processing in the past two decades.
What we do
Exterra Technologies is a Quebec‑based mineral processing technology company. We develop next‑generation processing technologies that help miners bring critical minerals to market faster, at lower cost, and with a smaller environmental footprint.
Our Technologies
Our platform is anchored in ARC™ (Acid Regeneration Cycle) — a proprietary technology that recycles the acids and bases used to extract metals from ore, in a closed loop, on site. Around ARC, we build full processing flowsheets adapted to each commodity and each ore type.
Impacts
Make more minerals bankable, sooner.
