Why Become a Partner — Olivier Dufresne
Exterra pioneers a revolutionary approach to transforming mining waste into valuable low-carbon products and solutions. With this funding, we'll accelerate commercializing our dual-pronged platform that valorizes over 90% of minerals from asbestos residues while creating one of the shortest nickel supply chains for EV electrification in North America. This Series A marks a pivotal moment as we move toward commercial operations and demonstrates how mining can enable an equitable, sustainable net-zero future.

Why Become a Partner — Pascal Lanctot
Finding new ways to mine critical minerals is essential to the energy transition. Exterra's technology converts asbestos tailings, an abundant resource in Canada, into minerals such as magnesium oxide that is used to sequester carbon, nickel that is used in making batteries, and silica that is used in building materials. That's exactly the type of innovative, impactful company that BDC Capital wants to support.
