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

(OTCQX: LITOF) ("Frontier" or "the Company"), is pleased to announce progress on fieldwork

activities supporting Phase 1 of the definitive feasibility study on the PAK Lithium Project and provide

an exploration update, including details on the maiden drillhole at the Ember LCT pegmatite, located

1 km west-northwest of the Spark deposit.

Press Release

Sept 25, 2023

"Results from PL-138-24 have extended the high-grade lithium zone at surface to a depth of 40

metres, further enhancing the exploration potential of the pegmatite" states

Garth Drever

, VP

Exploration "Structural measurements on the outcrop and from oriented drill core suggest a West

Southwest-East Northeast orientation of the Ember pegmatite which is consistent to the Spark

deposit suggesting a possible en echelon structural relationship. Since they share similar textural and

mineralogical features, the unexposed potential of Ember could prove to be significant."

During the same period, three condemnation diamond drill holes were completed on proposed

stockpile sites for definitive feasibility study and a small-scale regional exploration program was

completed. Field mapping and prospecting on claim blocks north of the mining leases identified

target areas that will require further work, including detailed mapping and channel sampling. A

lithogeochemical orientation survey was initiated by sampling host rock at the Spark and Bolt

pegmatites and surrounding areas, including the Ember pegmatite. The objective is to assess the

potential of identifying unexposed pegmatites by vectoring towards areas of higher fractionation.

Figure 1 is a compilation map shows the location of the two channels and drill hole PL-138-24 at

Ember in both plan and section view. The dashed lines on the lower right map outlines the potential

extension of the Ember pegmatite which is also an area of glacial ground moraine with abundant

glacial erratics (boulders) of varying size and composition. Further work is required to determine the

thickness of the overlying glacial material away from the exposed portion of the pegmatite.

DDH PL-138-24

Drill hole PL-138-24 was designed to follow up on the results from channel samples CH-52 and CH-53 and test the Ember LCT pegmatite outcrop at depth. The

results confirm that the LCT pegmatite extends 40 meters below the surface, with a slightly wider zone than expected but a lower grade compared to the

surface channel samples.

In addition to the diamond drilling at Ember, activities to advance the PAK Lithium Project are

ongoing. These include work in support of the mine and mill definitive feasibility study, environmental

baseline and monitoring to support permitting, and community engagement. During May and June,

geotechnical drilling and test pits were conducted on potential infrastructure sites, including waste

rock stockpiles, tailings management, and mine and mill facilities. From August to September, a

Stage 2 archaeology field investigation was completed by a licensed archaeologist with participation

from a local First Nation community. All environmental baseline studies focused on the mine and mill

were concluded in November, with final reports set for release by the end of 2024. These efforts

support ongoing permitting advancement and community engagement with First Nations focused on

creating a stronger understanding of the project and mitigating any concerns brought forward.

Due Diligence

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

Garth Drever, P.Geo., the qualified person ("QP") under the definitions established by National

Instrument 43-101 -

Standards of Disclosure for Mineral Projects

. Under Frontier's QA/QC

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

Val Caron, Ontario

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. A Reflex EZ-Trac

survey instrument was used every

50m

downhole and again at the end of each hole when rods were

pulled out. A Reflex North Finder APS unit was utilized to complete accurate positioning and

orientation of the drill collar upon setup. 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-half bagged for analysis. Sample blanks along with lithium 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 AGAT Laboratories Ltd. (AGAT) in

Thunder Bay, Ontario

for sample preparation and to

Mississauga, Ontario

for processing and

quantitative multi-element analysis. AGAT is an ISO accredited laboratory. The core is stored on site

at the Company's Knox exploration camp.

About Frontier Lithium

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

integrated domestic supplier of spodumene concentrates for industrial users as well as battery-

grade lithium hydroxide and other chemicals 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 contains

North America's

highest-grade lithium reserves and is the largest

Ontario

by size. The project encompasses close to 27,000 hectares and remains largely

unexplored; however, since 2013, the company has delineated two premium spodumene-bearing

lithium deposits (PAK and Spark), located 2.3 kilometres apart. Exploration is continuing on the

project through two other spodumene-bearing discoveries: the Bolt pegmatite (located between the

PAK and Spark deposits), as well as the Pennock pegmatite (25 kilometres northwest of PAK

deposit within the project claims). A 2023 Pre-Feasibility Study "National Instrument 43-101

Technical Report PFS PAK Lithium Project" by BBA E&C Inc., delivered a 24-year project life,

delivering a post-tax NPV(8%) of

US$1.74 billion

and IRR of 24.1% as per the press release

disseminated on

May 31, 2023
