Frontier Lithium has successfully produced battery grade lithium chemicals from its own high-

quality spodumene resource

from the PAK deposit, part of the PAK Lithium Project in

Ontario

Frontier is currently conducting additional bench-scale testing of a third-party's patented alkaline

process route to produce lithium hydroxide from the company's second Spark 'open pitable'

resource.

This work builds on Frontier Lithium's [strategy, plan, desire] to… [use information from Trevor's

various process options to be utilized for piloting to support Pre-Feasibility Study (PFS).

/CNW/ -

Frontier Lithium Inc. ("Frontier" or "the Company")

has successfully produced battery-

quality lithium hydroxide monohydrate (LiOH-H2O) through a reputable third-party firm using its

crystallization process technology from a purified lithium hydroxide (LiOH) solution produced

by Frontier Lithium. The lithium salts were produced from 'ore-to-hydroxide' sulphate conversion

route by a mini-pilot plant using core samples taken from the PAK Lithium Project's PAK deposit.

Test work results are shown in Table 1.

Trevor Walker

, President and CEO of Frontier Lithium stated, "We continue to progress, de-risk and

execute on our plan to build a fully-integrated lithium chemicals company to service the global battery

and electric vehicle industry." He also added "We are looking to complete lithium chemicals process

selection by year-end and will then commence subsequent piloting and demonstration programs

necessary to deliver the feasibility of an optimized process with innovative technology necessary for

building a commercial lithium chemical processing plant in

North America

The program results reflect Frontier's ability to produce concentrate and lithium hydroxide from the

PAK Lithium Project. The Government of

Ontario

is financially supporting the program of

conventional direct conversion sulphate and novel sulfate-free processing of spodumene

concentrates. The test work will support the PFS study currently being conducted to assess the

viability of a vertically integrated chemical company through operation of a spodumene mine and

concentrator at the PAK Lithium Project to feed lithium chemicals plant operation in the Great Lakes

region of

North America

About Frontier Lithium Inc.

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

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

North America

Frontier owns 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. It is a pure play

lithium company with the largest land position in the Electric Avenue, a premium lithium mineral

district located in

Northern Ontario

About the PAK Lithium Project

The PAK Lithium Project encompasses 26,774 hectares at the south end of

Ontario's

Electric

Avenue, the largest land package hosting premium lithium-bearing pegmatites in

Ontario

. 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 from each other. A 2021 preliminary economic assessment of a fully

integrated lithium operation utilizing spodumene concentrate generated from the Pak lithium project

resource – (1) Measured and Indicated resource of 10.49 Mt averaging 1.78% Li

O and Inferred

resource of 18.48 Mt averaging 1.45% Li

O - to achieve downstream conversion for production of

battery-quality lithium chemicals (National Instrument 43-101 technical report titled "Pak Property" by

BBA Engineering Ltd., issued on

April 5, 2021

) 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. Considerable

exploration upside is supported on the Pak lithium project through two other spodumene-bearing

discoveries: the Bolt pegmatite (located between the Pak and Spark deposits) as well as the

Pennock pegmatite (a further 30 kilometres northwest of Pak within the project claims).
