Commenting on recent developments, President and Chief Executive Officer Trevor Walker stated:

"This quarter marks a number of important milestones for Frontier Lithium. We filed the Mine and Mill Feasibility Study, confirming the potential for a long-life operation producing an estimated 200,000 tonnes of spodumene concentrate annually, supported by highly competitive operating costs. Environmental baseline studies continue to advance, and Fluor Canada Ltd. has been appointed to lead the feasibility study for our lithium conversion facility, which is expected to be delivered in the first half of 2027.

Frontier Lithium was also proud to join Canada's mission to Germany, where a new cooperation on critical minerals was announced. Our PAK Lithium Project in northern Ontario hosts North America's highest-grade known hard-rock lithium resources, with the potential to support a fully integrated mine, mill, and conversion facility. With strong government support and aligned with the perspectives of our Indigenous partners, we are working to deliver a secure and responsibly sourced lithium supply for North America's electric vehicle and battery markets. Representing Frontier Lithium alongside Minister Hodgson in Berlin reflects both the progress our team has made in Ontario and Canada's broader commitment to sustainable battery materials for the global energy transition. This trade mission is a strong reminder of why we remain focused on our vision, and we are grateful to our partners, communities, and supporters who make milestones like this possible."

As of June 30, 2025, the Company had cash and cash equivalents of $15 million, providing a strong position to cover corporate and administrative expenses and advance its planned business objectives.
