Frontier Lithium Welcomes Start of Construction on the Berens Bridge & Road Project

GREATER SUDBURY, ON, Feb. 23, 2026 /CNW/ - Frontier Lithium Inc. (TSXV: FL) (FRA: HL2) (OTC: LITOF) ("Frontier" or the "Company") welcomes today's announcement by The Honourable George Pirie, Ontario's Minister of Northern Economic Development and Growth, confirming that construction has begun on the Berens Bridge and Road Project (available here). The construction of the bridge will be completed through an agreement with Pikangikum First Nation and Whitefeather Forest Community Resource Management Authority ("WFCRMA") with a general contractor to oversee the construction. All construction permitting will be secured and held by WFCRMA for the construction activities and the construction will be completed in accordance with these detailed designs.

The Berens Bridge & Road Project will deliver:

• A two-lane bridge across the Berens River in Northern Ontario

• More than 30 kilometres of new and upgraded all-season road links

Improved year-round access for several Treaty #5 First Nation communities. The Berens Bridge & Road infrastructure will enhance safety, reduce the cost of goods, and improve access to essential services for thousands of residents across the region. Pikangikum and WFCRMA have selected a general contractor, for the construction of the Berens River Bridge. Rock drilling and blasting began last week to produce materials required to prepare the bridge site. Additional onsite work, including construction of a temporary bridge, will continue through the spring (2026), with the final, permanent bridge expected to be completed in 2028.

Minister Pirie's leadership has been central to advancing infrastructure that strengthens northern communities, reduces barriers to development, and supports Ontario's growing critical minerals sector. Today's announcement builds on a series of provincial initiatives in 2026 aimed at expanding transportation infrastructure, modernizing permitting through the recently enacted, One Project, One Process ("1P1P"), strengthening energy reliability, and supporting economic reconciliation with Indigenous communities.

"Ontario's commitment to building and upgrading northern infrastructure is creating real momentum in the region," said Trevor Walker, President and Chief Executive Officer of Frontier Lithium. "The start of construction on the Berens Bridge and Road Project is a milestone for Pikangikum First Nation and neighbouring communities, and we applaud Minister Pirie and community leaders for advancing this transformative work."

"This progress aligns with the pathway Ontario is building for critical minerals," added Mr. Walker. "Improved all-season access is essential for community well-being and for responsibly advancing projects like Frontier's PAK Lithium Project. We remain committed to working in partnership with Indigenous communities and governments as the region continues to grow."

The announcement reinforces Ontario's broader strategy to accelerate responsible development in its Northern region. In addition to investments in strengthening transmission lines, winter roads, and clean energy projects, and supported by the new 1P1P permitting model, the Province of Ontario is establishing a predictable and coordinated environment that enables the responsible development of new clean-energy supply chain projects.

Frontier congratulates Pikangikum First Nation, regional leadership, and the Province of Ontario on this important milestone of initiating construction on the Berens River Bridge and Road Project and looks forward to continued collaboration as construction moves forward.
