FRONTIER LITHIUM'S PAK PROJECT FIRST

SELECTED UNDER ONTARIO'S "ONE

PROJECT, ONE PROCESS" FRAMEWORK TO

ACCELERATE MINE PERMITTING

Selection underscores Frontier's leadership in advancing responsible lithium development and supply

chain security in

Northern Ontario

.

TORONTO

,

Oct. 29, 2025

/CNW/ - Frontier Lithium Inc. (TSXV: FL) (OTC: LITOF) (FRA: HL2)

("Frontier" or "the Company") is pleased to announce it has been selected to participate in

Ontario's

One Project, One Process ("1P1P") Framework Guidance initiative. 1P1P is an important

step in modernizing and streamlining

Ontario's

provincial permitting process for advanced mineral

development projects.

The 1P1P framework is designed to reduce government review timelines by up to 50 percent for

advanced exploration and mine development projects in

Ontario

, ensuring more timely and consistent

permitting decisions. The 1P1P initiative promotes a coordinated and efficient regulatory approach

that supports

Ontario's

critical mineral strategy by fostering greater collaboration among provincial

ministries and agencies and Indigenous peoples. Frontier's participation in the framework

underscores its readiness to advance its flagship PAK Lithium Project ("PAK Lithium Project" or

"Project") responsibly within this modernized system, helping accelerate the path from exploration to

development while maintaining high standards of environmental stewardship and Indigenous

engagement.

Located in

Northwestern Ontario

, in the traditional territory of people guided by Anishinninew law,

Deer Lake

, Keewaywin, North Spirit Lake and Sandy Lake First Nations, the Project represents a

high-grade, large-scale hard rock lithium resource, an essential building block for

Canada's

critical

minerals supply chain. This milestone recognizes Frontier's long-standing commitment to responsible

resource development and positions the PAK Lithium Project as a model for integrated and

sustainable project development.

The Project is expected to deliver strong and lasting benefits for

Northern Ontario

. Based on initial

findings from an upcoming socioeconomic study that indicates the Project could generate up to $1.5

billion in gross domestic product ("GDP"), $124 million in tax revenues, and create more than 2,000

full-time jobs during construction alone. Once operational, it is projected to contribute $182 million in

GDP annually, $11.6 million in annual tax revenues, and support nearly 1,000 long-term positions,

while generating an estimated $2.4 billion in total corporate income and mining tax revenues over its

lifespan. These benefits extend beyond economics—creating opportunities for First Nations and local

communities through employment, training, and infrastructure development, including all-season road

access and workforce education programs.

Since initiating exploration in 2013 of the Project, Frontier has advanced extensive economic and

technical studies, taken time to deepen its engagement with Indigenous and local communities, and

aligned its development plans with both Provincial and Federal priorities. Frontier's vertically

integrated strategy, including its proposed lithium conversion facility in

Thunder Bay, Ontario

, is

designed to support a fully domestic, sustainable mine-to-battery supply chain.

"We welcome the opportunity to participate in the 1P1P initiative," said Trevor Walker, President and

Chief Executive Officer of Frontier. "Clarity and predictability in permitting are key to unlocking

investment, accelerating project timelines, and delivering on

Canada's

critical minerals strategy. This

initiative represents a meaningful step forward for industry, government, and Indigenous communities

alike."

Frontier's participation in the 1P1P framework aligns with broader Provincial actions to unlock

Northern Ontario's

growth potential. The proposed twinning of the transmission lines between

Dryden

and

Red Lake

will strengthen grid capacity and enable electrification of new mining projects

like the PAK while supporting community growth and clean energy access across the region. This

infrastructure investment reflects a shared vision of economic reconciliation, sustainable regional

development, and a clean, electrified future for

Northern Ontario

.

About Frontier Lithium

Frontier Lithium Inc. is a pre-production mining company with an objective to become a strategic and

integrated supplier of premium spodumene concentrates as well as battery-grade lithium salts to the

growing electric vehicle, and energy storage markets in

North America

. The Company's PAK Lithium

Project maintains the largest land position and resource in a premium lithium mineral district located

in

Ontario's

Great Lakes region.

About the PAK Lithium Project

The PAK Lithium Project is a fully integrated critical minerals initiative in

Ontario

, developing a high-

grade, large scale lithium resource. Operated as a joint venture between Frontier (92.5%) and

Mitsubishi Corporation (7.5%), the project is advancing in parallel with a mine and mill, north of

Red

Lake, Ontario

and a downstream lithium conversion facility in

Thunder Bay, Ontario

, which are both

key to supporting a secure domestic lithium supply for the clean energy transition. A 2025 Mine and

Mill Feasibility Study (FS), prepared by DRA Global Limited and entitled National Instrument 43-101

Technical Report FS PAK Lithium Project, Mine and Mill, outlines a 31-year Project life with an after-

tax net present value of

$932 million

at an 8% discount rate and an after-tax internal rate of return of

17.9%.These results have been disclosed in the Company's press release dated

May 28, 2025

, and

the accompanying technical report was filed on SEDAR+ (
