Frontier Lithium Plans Thunder Bay, Ontario, Canada, Chemical Production Operations

03/10/2025
Lithium mineral and salts company Frontier Lithium plans to establish production operations in Thunder Bay, Ontario, Canada.

The new critical mineral refinery, a joint venture between the company and Japan-based Mitsubishi, will be located on a 183-acre industrial site. Operations are scheduled to begin in 2029.

“At Frontier Lithium, our vision is to become North America's leading supplier of critical materials. We are grateful for the confidence the Government of Canada has placed in this vision and for its support in developing our lithium conversion facility in Thunder Bay. This support will help ensure that we maximize the economic benefits of our natural resources while supporting the global transition to clean energy, and it will strengthen Canada’s position as a leader in the global race for safe and secure critical minerals. We look forward to collaborating with the government as we continue to progress our project,” said Trevor Walker, President and CEO, Frontier Lithium.

Frontier has received up to $6.1 million in conditionally approved funding under the Critical Minerals Infrastructure Fund. “Ontario’s abundant supply of critical minerals is one of our province’s greatest advantages. We’re so pleased to welcome Frontier Lithium’s interest in expanding its production of strategic battery minerals right here in Ontario, which will support our growing end-to-end critical minerals and electric vehicle battery supply chain. By continuing to grow Ontario’s critical minerals industry, we can strengthen our economy and protect Ontario workers and jobs, no matter what,” noted The Honourable Victor Fedeli, Ontario’s Minister of Economic Development, Job Creation and Trade.

Frontier Lithium is aiming to produce battery-grade lithium hydroxide and lithium salts to the growing electric vehicle and energy storage markets in North America as well as be a premium mineral concentrates supplier for high quality glass manufacturers.

"We are pleased to welcome this proposal from Frontier Lithium,” added Jennifer Block, Interim CEO of Invest Ontario. “We remain focused on securing investments which strengthen Ontario's leadership in critical supply chains and send an important signal to investors that Ontario is ready to be their partner."
