CANADA —Frontier Lithium has contracted engineering firm DRA Americas Inc. to deliver an updated feasibility study for the mining and milling operations at its PAK Lithium Project in northwestern Ontario, Canada. Targeted for completion in the first quarter of 2027, the revision aims to incorporate value engineering findings, optimize process design, and refine water and mass balance models to ready the asset for final investment decisions and construction financing.
Frontier Lithium Inc. is a Canadian critical minerals exploration and development company focused on advancing its high-grade spodumene asset in the Great Lakes region. Operating as a joint venture with Mitsubishi Corporation holding a 7.5% stake, the firm plans to build both an open-pit mine and mill alongside a downstream lithium chemical conversion plant in Thunder Bay, Ontario.
The updated technical review builds upon a 2025 study that evaluated a 31-year operational lifespan for the lithium deposit, projecting an after-tax net present value of 932 million CAD at an 8% discount rate. The upcoming iteration will reassess throughput scenarios, operational expenditures, and geotechnical parameters while integrating ongoing permitting initiatives conducted under Ontario's One Project, One Process framework.
This development carries strong strategic significance for North American battery supply chains as industrial policy increasingly favors localized sourcing of critical raw materials. By refining engineering models and strengthening project economics, the joint venture aims to derisk execution pathways, enabling automotive manufacturers and battery production facilities to secure stable domestic spodumene concentrate.
