Liminal by WMC, in partnership with its joint venture & feedstock provider, is developing a state-of-the-art cobalt refinery in Eastern Canada. The location was strategically chosen for its proximity to the local EV-battery ecosystem, low-cost green electricity, local reagent supply, efficient transport infrastructure and streamlined permitting process.

The facility is set to become North America's largest supplier of:

• Cobalt sulphate – Production capacity to 900,000 EV batteries, strengthening the domestic battery supply chain.
• Alloy-grade cobalt metal – Supporting the aerospace sectors while reducing reliance on imports outside North America.

Ethical & Secure Supply Chain

• 100% RMI-certified and IRA-compliant feedstock supplemented by recycled cobalt to ensure ethical and responsible sourcing.
• MoUs secured with suppliers to enhance long-term supply security.

Sustainability & Cost Efficiency

Developed through a completed Pre-Feasibility Study and bench-scale test-work, the facility’s innovative flowsheet is designed to prioritize:

• Near-zero waste & emissions – Minimal solid waste, zero liquid effluent, and almost no air emissions.
• Cost competitiveness – Strategic byproduct valorisation and access to low-cost power drive efficiency over traditional refining methods.

Project Status & Next Steps

• A prime industrial site is secured.
• Environmental permitting is progressing.
• Pilot testing and Definitive Feasibility Study (DFS) are underway.
• Customer pre-qualification is expected to commence in Q3 2025.

By combining sustainable innovation with North American supply chain security, Liminal is setting a new benchmark for responsible cobalt production.
