Pre-Feasibility Study Overview

1. LITHIUM CHEMICALS FOR THE NORTH AMERICAN ELECTRIC VEHICLE MARKET

The PAK Project has the ability to produce 7,360 metric tonnes of lithium carbonate and 12,

520

m.t.

of lithium hydroxide annually. This production tonnage meets the specific requirements of

original equipment manufacturers (OEMs), such as automotive companies operating in the North

American electric vehicle market. As the electric vehicle market continues to evolve and expand,

the ability to adapt and meet changing customer demands becomes crucial. The lithium

chemicals to be produced by Frontier Lithium will be tailored to the needs of the industry,

supporting the growth of electric vehicles manufacturing in the region and building in optionality

for the future demand profiles through adjustments in production capacity and product mix to

align with future market trends and customer preferences.

2. A PHASED APPROACH

The development of the PAK project and hydromet chemical plant will be completed in phases

to allow for efficient resource allocation, to minimize upfront capital expenditure, and de-risk

project execution. The first phase will focus on the production of spodumene concentrate to

generate revenue and support the concurrent development of necessary infrastructure to build

the proposed mine-to-lithium hydroxide chemical plant facility. Implementing a phased approach

also enables a more streamlined and controlled project development process, enabling a

thorough understanding of the resource base and an optimization of the refining process in

advance of chemical plant construction. This approach ensures that the subsequent refinery

build-up is well-informed, efficient, and aligned with market demand.

3. GROWING REGIONAL DEMAND

The North American electric vehicle market is experiencing significant growth, with strong

commitments of over CAD$25 billion to build Ontario battery capacity by 2030. This strong

regional growth provides a favorable market environment for the lithium project. The project can

capitalize on its strategic North American location, the growing demand for electric vehicles and

the need for lithium chemicals to support battery production.

The commitments to build Ontario battery manufacturing capacity indicate a long-term future in

sustainable transportation and the development of the electric vehicle ecosystem. By supplying

locally produced lithium chemicals, the project can contribute to the regional supply chain,

reduce dependence on imports, and strengthen the overall resilience and competitiveness of the

North American electric vehicle market.

4. OPPORTUNITIES FOR FURTHER UPSIDE

The project offers opportunities for further upside through the potential conversion of additional

mineral resource to mineral reserves. The PFS reserve calculation includes only one-third of the

identified resources. None of the 32.4 million tonne of inferred mineral resources were included

in the PFS mineral reserves. This indicates significant exploration potential and the possibility of

scaling the project.

Frontier has a strong track record in resource exploration and development, and the continued

exploration efforts within the PAK Lithium Project could uncover additional mineral resources.

The potential to tap into additional resources ensures the project will be responsive to future

market demands and supports long-term sustainability.

Due Diligence

All scientific and technical information in this release has been reviewed and approved by

Todd

McCracken

, P.Geo., Director – Mining & Geology –

Central Canada

, BBA E&C Inc., the qualified

person (QP) and

Garth Drever

, P.Geo., VP Exploration for Frontier Lithium Inc. the qualified person

(QP) under the definitions established by National Instrument 43-101. Under Frontier's QA/QC

procedures, all drilling was completed by Chenier Drilling Ltd. of

Val Caron, ON

using thin-walled

BTW drill rods (4.2 cm core diameter) and a Reflex ACT III oriented core system. Using the Reflex

system, the drill core was oriented and marked as it was retrieved at the drill. The core was boxed

and delivered to the Frontier core shack where it was examined, geologically logged and marked for

sampling. The core was photographed prior to sampling. Using a rock saw, the marked sample

intervals were halved with one halve bagged for analysis. Sample blanks along with lithium, rubidium

and cesium certified reference material was routinely inserted into the sample stream in accordance

with industry recommended practices. Field duplicate samples were also taken in accordance with

industry recommended practices. The samples were placed in poly sample bags and transported to

Red Lake

by Frontier employees and then shipped to AGAT Laboratories Ltd. (AGAT) in

Mississauga, ON

for quantitative multi-element analysis. AGAT is an ISO accredited laboratory. The

core is stored on site at the Pakeagama Lake exploration camp.
