Frontier Intersects 326.6M of Pegmatite Averaging 1.92% Li2O, Including a 50M Zone of 2.98% Li2O

Drill Results

FRONTIER INTERSECTS 326.6M OF

PEGMATITE AVERAGING 1.92% Li2O,

INCLUDING A 50M ZONE OF 2.98% Li2O

SUDBURY, ON

,

Oct. 11, 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

11,150m

of drilling in 34 holes as of

September 11th, 2022

.

Analysis from 4 of the holes are reported herein.

DDH PL-065-22 intersected a total of

171.5m

of pegmatite averaging 1.57% Li

O and thin

sheets of mafic rafts within the pegmatite as expected. Collared north of the Spark Pegmatite in

mafic volcanic

30m

west of PL-062-22, hole was drilled to convert inferred material at depth

and to provide a northern contact of the Spark Pegmatite.

"After tripling the metres drilled since the Resource update in

March 2021

and targeting the Inferred,

it is safe to say that the model remains robust and there will be substantial new Inferred." states

Garth Drever

, V.P. Exploration. "The Spark deposit remains open in all directions with predictable

grades and widths."

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. Frontier is now focused on defining the

limits of the pegmatite and deepening some of the initial holes such as PL-065-22, that had been

terminated earlier in the program.

Other Matters

The Company has elected to introduce a phased approach in the Preliminary Feasibility Study

currently underway by firstly advancing a mine and mill development to initially produce premium

spodumene concentrates in Phase I. Phase II plans will increase mine and mill production to feed its

downstream refinery to produce lithium chemicals for the energy storage and electric vehicle battery

market. As a result of the Phased approach, the Company is updating delivery of the PFS to

calendar Q1 2023.

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 with an objective to become a strategic 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 maintains the largest land position and resource in a new premium lithium mineral

district located in

Ontario's

Great Lakes region.

About PAK Lithium Project

The PAK Lithium Project is one of the highest quality known lithium mineral resource in

North

America

due to its high-grade and low impurity properties in the pegmatite ore material and the

spodumene mineral. The Company published a Preliminary Economic Assessment ("PEA") in

April

2021

that indicated an after-tax Net Present Value ("NPV") at an 8% discount rate of US

$974 million

and a 21% after-tax Internal Rate of Return ("IRR") through a fully-integrated lithium operation

utilizing spodumene concentrate generated from the PAK Lithium Project to achieve downstream

conversion for production of battery-quality lithium chemicals and concentrate for the glass and

glass-ceramics market. For details, please refer to the NI 43-101 Technical report by BBA

Engineering Ltd. issued on

April 9, 2021

and filed under the Company's profile on SEDAR on

April

14, 2021
