GREATER SUDBURY, ON, July 31, 2025 /CNW/ – Frontier Lithium Inc. (TSXV: FL) (OTCQX: LITOF) (“Frontier” or the “Company”) is pleased to announce the commencement of the Definitive Feasibility Study (“DFS”) for the lithium conversion facility (the “Project”) in Thunder Bay, Ontario. As a second definitive feasibility study, this work builds on the positive outcomes of the recently completed mine and mill DFS, with a dedicated focus on evaluating a refinery supplied by Frontier Lithium’s own production and potential third-party feedstock. The Company has awarded the feasibility scope for the Project to Fluor Canada Ltd. (“Fluor”), a leading engineering and construction company that provides engineering, procurement, construction, maintenance, and project management services across various industries.
Fluor will work with Frontier to deliver the comprehensive DFS, covering various work packages such as infrastructure, process and design, cost estimation, economic valuation, procurement and a technical report for Frontier. Fluor will also advance execution planning, and coordination with specialized consultants supporting technical studies, reporting, and environmental assessments.
“After a thorough evaluation process, we have selected Fluor based on their global and North American expertise in critical minerals development and their proven track record delivering large-scale lithium processing and refinery projects,” said Trevor Walker, President and Chief Executive Officer of Frontier. “Advancing this phase of the Project is critical not only for Frontier, but for ensuring that we continue to build a successful made-in-Canada EV battery supply chain. We’re confident in the lithium refining experience of our project team and excited to move forward into this next phase”.
The DFS will initially deliver a preliminary capital cost estimate laying the foundation for Frontier’s first commercial refining facility and long-term production strategy. These outcomes will also support the goal of finalizing the contribution agreement’s with both federal and provincial governments as previously announced in the Company’s press release on March 4, 2025 and highlighted in the Province of Ontario budget on May 15, 2025. Frontier expects to complete the federal and provincial government agreements in 2025/2026 and deliver the feasibility study within the next 18 months. Frontier may consider future updates to reflect integrated economics of the mine and mill and refinery projects, subject to funding progress.
The proposed Project, which is planned for the recently acquired Mission Island site (Figure A) in Thunder Bay, Ontario, will be designed to produce approximately 20,000 tonnes of lithium carbonate equivalent (LCE) lithium hydroxide salts annually, once in production. This output could support battery production for up to 500,000 electric vehicles per year. The Project will also be designed to accommodate supply from other lithium deposits both in Canada and internationally, strengthening Canada’s role in the global battery supply chain.
Frontier remains committed to sustainable resource development and to working collaboratively with Indigenous community partners, stakeholders, and government agencies to ensure the successful execution of this nationally significant critical minerals project in Thunder Bay, Ontario.
