FRONTIER LITHIUM PROVIDES CRITICAL MINERALS INFRASTRUCTURE FUNDING UPDATE INCLUDING THE ROAD CONNECTING THE PAK LITHIUM PROJECT

Frontier Lithium Inc. has provided a progress update on the infrastructure projects supported by Natural Resources Canada's Critical Minerals Infrastructure Fund for the company's flagship PAK lithium project in Northwestern Ontario.

In March, 2025, Frontier finalized contribution agreements under CMIF, securing up to approximately $6.1-million in non-repayable contribution funding to advance the following two projects:

• All-season road engineering and design project (Junction Road): preconstruction engineering, design, permitting and environmental studies for approximately 56 kilometres of an all-season two-lane road required to connect the PAK project to Ontario's provincial highway network;
• PAK clean energy project: engineering, design and permitting for a substation and transmission line to integrate the PAK project into the Wataynikaneyap power grid, ensuring long-term, sustainable electricity supply.

Frontier continues to advance engineering, environmental, permitting and indigenous engagement activities to support shovel-ready status for these projects, and Frontier intends to apply to stream 2 under the CMIF program to be reimbursed for 50 per cent of the eligible costs for these projects.

Project progress in 2025

In 2024 and 2025, over $3-million has been invested in advancing critical infrastructure under the CMIF program. The company anticipates allocating up to an additional $8.9-million by 2028 as activities expand, including consultation, permitting and engineering, for both these projects, and Frontier will apply under the CMIF program to be reimbursed for 50 per cent of the eligible costs for these projects.

Over the course of 2026, the all-season road engineering and design project plans to complete consultation and the remaining 20 per cent of the engineering plans, designate the preferred route, and finish the permitting process under Ontario's One Project One Process Framework. This work is anticipated to cost $2.6-million and will aim to enable construction of the all-season Junction Road to begin as early as 2027.

The capital required for the PAK clean energy project in 2026 is estimated to be $2.9-million, which will complete assessments for the required technical upgrades to the existing infrastructure, the environmental assessments and permitting requirements for on-lease infrastructure and any remaining geotechnical drilling that is required for site infrastructure impacted by the electricity connection. These works are being completed alongside the Province of Ontario's October announcement of the twinning of the power lines to Red Lake, Ont., to support new mining projects, such as the PAK project, located north of Red Lake.

Strategic importance

These projects are integral to both Ontario and the Canadian Critical Minerals Strategy, addressing infrastructure gaps essential for bringing critical mineral deposits like the PAK deposit into production. Frontier's PAK project is recognized as one of Ontario's largest and highest-grade lithium resources, forming the foundation for a fully integrated mine-to-chemical operation to supply lithium chemicals for electric vehicle and energy storage markets across North America.

"Road and power investments are generational infrastructure, not just for the PAK lithium project, but also for others within the region, including local and indigenous communities. As we advance permitting and preconstruction, we are ensuring benefits flow regionally while Canada strengthens a secure, domestic critical minerals supply chain," said Trevor Walker, president and chief executive officer of Frontier.

"Building the infrastructure needed to unlock Canada's critical minerals potential is essential to getting Canadian minerals to markets, which will diversify our trade, strengthen our economic and national security and sovereignty, create good domestic jobs, and support the clean energy transition. Through the Critical Minerals Infrastructure Fund, our new government is investing in roads and clean power that not only help move projects like Frontier's PAK lithium project toward production, but create significant benefits for the communities around these projects. Canada has what the world wants, and we are building big things again, to make sure we can deliver for Canadians and allies abroad," said Tim Hodgson, Minister of Energy and Natural Resources.
