FRONTIER LITHIUM HIGHLIGHTS CONTINUED ADVANCEMENT THROUGH 1P1P TO SUPPORT REGIONAL ROAD INFRASTRUCTURE

Frontier Lithium Inc. has provided an update on recent developments supporting advancement through Ontario's one project, one process permitting framework, with a focus on co-ordinated regulatory activities, project access and regional infrastructure initiatives across Northwestern Ontario. These developments support continuing collaboration among governments, indigenous communities, regulators and industry as permitting advances in support of responsible critical mineral development.

Frontier's PAK lithium project is the first project in Ontario to advance through the 1P1P framework, which promotes a 50-per-cent reduction in regulatory review timelines and the completion of permitting within 24 months. It is also the first project accepted into the government of Canada's Permitting Coordination for Clean Growth Projects initiative, which supports projects that are not subject to the Impact Assessment Act. Under these two co-ordinating processes, federal and provincial reviews are aligned to advance project permitting, maximize technical reviews and share a fulsome understanding of all aspects of the project.

The key focus for year one of 1P1P has been permitting the Junction Road, an approximately 56-kilometre section of all-season road that, as planned, will connect the approved Branchwood Road to the junction point between community winter roads near the PAK lithium project. As the most advanced component of the integrated authorization and permitting plan, the Junction Road's class environmental assessment and associated permits are on track for completion in first quarter 2027.

The Junction Road is expected to deliver lasting access benefits for the region while establishing the access required to support the potential future development of the PAK lithium mine. As an immediate step under 1P1P, Frontier is supporting direct dialogue between the province and the nations most directly impacted by the Junction Road.

Preconstruction work on the Junction Road, including engineering, design, environmental studies and permitting, has been supported to date by Natural Resources Canada's Critical Minerals Infrastructure Fund, under which Frontier secured approximately $6.1-million in non-repayable funding for the Junction Road and the PAK lithium project's electricity transmission connection. Frontier continues to work with both the government of Canada and the Province of Ontario on funding for the Junction Road, reflecting its role as shared regional infrastructure. The objective is to align construction funding with the permitting timeline so the road can advance to construction. The company looks forward to providing further updates as these discussions advance.

"This is about building the understanding, trust and infrastructure foundation required for responsible development over time," said Trevor Walker, president and chief executive officer of the company. "Ontario's critical minerals strategy recognizes that generational opportunities in the North require co-ordinated permitting, indigenous participation and enabling infrastructure. Through 1P1P, the road and access-related permitting work is advancing on a nearer-term pathway while the mine-related components review will follow thereafter. That distinction matters, and our focus is on working respectfully with communities, regulators and governments as this first phase of regional access infrastructure advances."

Frontier remains focused on advancing the PAK lithium project in a disciplined, phased manner: moving Junction Road permitting toward its first quarter 2027 milestone, and targeting key permits for the broader project by fourth quarter 2027. Together with continued direct dialogue between the province and first nation rights holders, and transparent, on-the-ground engagement with regulators and communities, these steps build the regional access and relationships needed to support a secure domestic lithium supply chain in Ontario and across North America.
