/CNW/ - Frontier Lithium Inc. (TSXV: FL) (FRA: HL2) (OTCQX:
LITOF) ("Frontier" or "the Company") is pleased to announce the results for five 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 11, 2022
.
Analysis from 5 of the holes have been received and reported herein.
DDH PL-062-22 Intersected a total of
180.8m
of pegmatite averaging 1.55% Li
2
O with thin
sheets of mafic rafts within the pegmatite as expected. Collared north of the Spark Pegmatite
in mafic volcanic, hole was drilled to convert inferred material at depth and to provide a northern
contact of the Spark Pegmatite. Hole was terminated in pegmatite due to time constraints and
will extended later in the program.

DDH PL-070-22, PL-071-22 and PL-073-22 were collared proximal to each other and fanned
out to test both the northern upper and southern lower contacts with the mafic host rock. As
expected, they intersected diminishing proportions of pegmatite from west to east with an
increase in mafic rafts towards the east.

"We are extremely pleased with the drilling results to date." states
Garth Drever
, V.P. Exploration.
"The infill-drilling continues to be predictable, the pegmatite remains open in all directions and zones
of elevated tantalum and cesium along with lithium are being delineated."
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-062-22 was terminated in
pegmatite and PL-066-22 was ended in mafic volcanics due to PFS time constraints requiring quick
turn-around of analysis. With one month of drilling remaining in the current program, Frontier will
focus on defining the limits of the pegmatite and deepening many of the initial holes that had been
terminated earlier in the program.
Figure 1 is a location map showing the project area including Frontier's land tenure and location of
the three lithium-cesium-tantalum pegmatites.

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
