the PAK Lithium Project

GREATER SUDBURY, ON

,

Nov. 17, 2025

/CNW/ - Frontier Lithium Inc. ("Frontier Lithium" or the

"Company") is pleased to share the results of a third-party socioeconomic impact study (the

"Report") conducted by Ernst & Young LLP (EY) for the Company's proposed integrated mining and

processing operations in

Northwestern Ontario

(the "PAK Lithium Project" or the "Project"). The

Report outlines the significant economic and labour impacts of the Project, based on the latest mine

and mill Definitive Feasibility Study (DFS) and the conversion facility data from the Pre-Feasibility

Study (PFS). Frontier is currently advancing a DFS for the conversion facility.

Trevor Walker

, President and CEO, stated: "The PAK Lithium Project will deliver meaningful benefits

to

Northwestern Ontario

, driving economic growth, employment, and support for local businesses.

These positive impacts will cascade across the region, strengthening community prosperity and

enhancing economic vitality. At a broader level, the project supports multiple economic and national

security and defense objectives as described in both

Canada's

and

Ontario's

Critical Minerals

Strategies as well as the G7 Critical Minerals Production Alliance reinforcing the strength of

North

America's

battery supply chain and positioning

Canada

as a key contributor in the global energy

transition."

Local And National Benefits over the 33-year Project Lifespan

The PAK Lithium Project will have a transformative economic multiplier effect across

Northwestern

Ontario

, the Province, and country of

Canada

with anticipated increases to gross domestic product

("

GDP

"), labour income, and employment, reflecting its national significance. The Report assessed

the economic impacts of the two principal phases of the Project: construction and operations.

The Report also underscores the Project's transformative role in developing human capital, furthering

the aim of the

Canadian Sustainable Jobs Act

, and creating a stronger synergy between economic

growth and workforce development. With hundreds of workers, including Indigenous workers,

projected to be permanently employed full-time during operations, the Project will offer opportunities

in trades such as millwrights, mechanics, electricians, metallurgical engineers, and process

operators.
