PAK LITHIUM PROJECT SELECTED FOR CANADA INVESTMENT SUMMIT PROSPECTUS AND ONLY LITHIUM PROJECT INCLUDED IN ONTARIO'S DEAL BOOK

Frontier Lithium Inc.'s PAK lithium project has been featured in both the Canada Investment Summit Prospectus and Ontario's Deal Book, highlighting the project among strategic Canadian investment opportunities being showcased to global institutional investors.

The company's PAK lithium project was selected for inclusion in the Canada Investment Summit Prospectus, which was distributed to participants of the inaugural Canada Investment Summit. Announced by Prime Minister Mark Carney, the summit is being hosted by the government of Canada in partnership with the Canada Pension Plan Investment Board and the Public Sector Pension Investment Board, and will take place in Toronto, Ont., on Sept. 14 and Sept. 15, 2026.

The Canada Investment Summit Prospectus features 167 investment opportunities across eight sectors, including 63 projects in the mineral and metal category. Frontier's PAK lithium project is among a limited number of lithium projects identified in the prospectus, further highlighting the strategic importance of domestic lithium supply within Canada's critical mineral sector.

In addition, the PAK lithium project is also featured in Ontario's Deal Book, a collection of 15 major investment opportunities highlighted by the Province of Ontario during the summit. According to Premier Doug Ford, the Deal Book includes projects spanning critical minerals and mining, energy production and transmission, advanced manufacturing, and artificial intelligence. Frontier's PAK lithium project was one of only six mining and critical mineral projects included in the publication and the only lithium project featured among the 15 investment opportunities presented.

"We are pleased to see the PAK lithium project recognized in both the Canada Investment Summit Prospectus and Ontario's Deal Book," said Trevor Walker, president and chief executive officer of Frontier Lithium. "Together with the project's advancement through the One Project One Process framework and the growing focus on enabling infrastructure, this recognition demonstrates meaningful alignment between federal and provincial priorities. Institutional investors have consistently emphasized the importance of visible government support and infrastructure planning. These developments help establish the conditions needed to attract private capital and advance a secure, domestic lithium supply chain."

The PAK lithium project is one of Canada's most advanced lithium development projects and is being advanced with the objective of producing battery-grade lithium chemicals for the North American electric vehicle and energy storage markets. Frontier continues to advance permitting, infrastructure, engineering and financing activities as it progresses toward a final investment decision and the development of an integrated lithium mine and conversion facility in Northwestern Ontario.
