FRONTIER INTERSECTS 357.5m OF HIGH-

GRADE LITHIUM AVERAGING 1.63% Li2O

OVER A HORIZONTAL DISTANCE OF 110

METRES AND REMAINS OPEN

SUDBURY, ON

,

Aug. 17, 2022

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

LITOF) ("Frontier" or "the Company") is pleased to announce the results for four additional drill holes

completed during the Phase XII drill program on the Spark pegmatite which began in

May 2022

and

is currently in progress. The initial drill holes were designed to convert inferred material to the

indicated category for the planned open pit. The Spark pegmatite is one of the two delineated

premium spodumene-bearing lithium deposits on the PAK Lithium Project.

Highlights

Phase XII delineation and infill drilling with two drill rigs is currently being conducted, whereby,

the Company has completed

8,000m

of drilling in 24 holes at the time of this press release.

Currently, analysis from 8 of the holes have been received; 4 of which were reported in the

July 25

th

press release

and the remaining 4 are reported herein.

DDH PL-059-22 intersected

145m

of pegmatite over a

316m

interval from surface with an

average grade of 1.5% Li

2

O along with some minor mafic volcanic sheets (<

6m

apparent

width).

DDH PL-060-22 intersected

357.5m

of spodumene-bearing pegmatite averaging 1.63% Li2O

throughout the entire hole representing a horizontal distance of

110m

.

An enriched

112m

grading 370

, 0.62% Rb

.

Hole was terminated in spodumene-bearing pegmatite at

360m

(vertical depth of

345m

).

DDH PL-061-22 was collared in pegmatite intersecting

280.7m

averaging 1.42% Li

2

O.

Hole was terminated in mafic volcanics prior to intersecting the southernmost identified

zone of the pegmatite and will be extended.

DDH PL-068-22 intersected spodumene pegmatite zones typically 20 to

50 m

thick with grades

ranging from 1.42% to 2% Li

2

O;

Includes

12m

zone from 28 to

40m

averaging 3% Li

2

O.

Also includes elevated Ta (213 ppm Ta

) from 59.3 to

.

"So far there have been no surprises with the drill intersections." states

Garth Drever

, V.P.

Exploration. "Our modeling beneath the central indicated resource appears solid and drilling to the

west continues to intersect significant pegmatite zones."

The initial objective for the Phase XII drill program was to focus on converting the inferred resource

within the central portion of the Spark deposit at depth. DDH's PL-059-22 and 060-22 were

terminated in pegmatite and PL-061-22 was ended in mafic volcanics due to PFS time constraints

requiring quick turn-around of analysis. These and other holes will be extended later in the program.

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. 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-half 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 float plane and then

shipped to AGAT Laboratories Ltd. (AGAT) in

Thunder Bay

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 Pakeagama Lake exploration camp.

About Frontier Lithium

Frontier Lithium is a preproduction business that is targeting to become a manufacturer of battery-

quality lithium materials to support electric vehicle and battery supply chains in

North America

.

Frontier is developing the PAK Lithium Project which contains one of

North America's

highest-grade,

large-tonnage hard-rock lithium resources in the form of a rare low-iron spodumene. The project

continues to have significant exploration upside with potential to increase the lithium resource. The

Company is a pure-play lithium development opportunity with the largest land position in a premium

lithium mineral district located in

Northern Ontario

.

About PAK Lithium Project

The PAK Lithium Project contains

North America's

highest grade lithium resource that is top three in

size on the continent and is considered premium quality globally as a result of its rare low-iron

spodumene. A 2021 preliminary economic assessment (National Instrument 43-101 technical report

titled "Pak Property" by BBA E&C Inc., issued on

April 5, 2021

) delivered a fully integrated lithium

operation from the resource to achieve downstream conversion plan for production of battery-quality

lithium salts. The study resulted in an after-tax net present value (discounted at 8 per cent) of

$974-

million

(U.S.) with a 21-per-cent internal rate of return. The Project encompasses close to 27,000

hectares at the south end of

Ontario's

Electric Avenue, the largest land package hosting premium

lithium-bearing pegmatites in

Ontario

. The Project maintains a measured and indicated resource of

21.64 million tonnes (Mt) averaging 1.56 per cent lithium oxide (Li2O) and inferred resource of 20.87

Mt averaging 1.42 per cent Li2O. The Project covers 65 kilometres of the Electric Avenue's length

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. Considerable

exploration upside is supported 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).
