FRONTIER INTERSECTS 144M OF HIGH GRADE
LITHIUM AVERAGING 1.72% Li2O WITH SIGNIFICANT
CESIUM AND TANTALUM ZONES AT SPARK
SUDBURY, ON

July 25, 2022
/CNW/ - Frontier Lithium Inc. (TSXV: FL) (FRA: HL2) (OTCQX: LITOF) ("Frontier" or
"the Company") is pleased to announce the results for four of the drill holes completed during the Phase XII drill
program on the Spark pegmatite. Phase XII drill program that began in
May 2022
and is currently in progress. The
initial drill holes were designed to quickly 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 in-fill and delineation drilling with two drill rigs is currently being conducted, whereby, the Company
has completed
7,000m
of drilling in 22 holes at the time of this press release.
DDH PL-057-22 intersected
10m

2
O (assumed to be pollucite) within a high-grade (3.14% Li
2
O)
spodumene zone from 149.5 to
159.5m
.
A highly enriched
15m

172.5m
grading 1,335 ppm Ta

and 0.9% Rb

Hole was collared in pegmatite intersecting
110.7m
averaging 1.76% Li

DDH PL-058-22 intersected
239.4m
of pegmatite from 58.1 to
297.4 m
grading 1.3% Li

DDH PL-063-22 was collared in pegmatite intersecting

with
68.5m
of pegmatite averaging 1.58% Li

DDH PL-064-22 intersected
132.9m
of pegmatite from 114.1 to
247.0m
grading 1.33% Li
2
O;
Includes
7m
of elevated Sn (440 ppm SnO

) and Rb (0.51% Rb

.
Also includes elevated Ta (959 ppm Ta

) from 170 to180m.
"The exciting presence of the cesium mineral pollucite in the lithium zone intersected in DDH PL-057-22 suggests the
Spark pegmatite is well evolved mineralogically, and may be approaching the degree of fractionation attained by the
prolific Tanco pegmatite
(1)
at
Bernic Lake
,
Manitoba
where high-grade pollucite zones occur." states
Garth Drever
,
V.P. Exploration. "High fractionation could result in furthering the potential by-products beyond Lithium and Tantalum.
During the remainder of the Phase XII drilling we intend to investigate this new pegmatite zone to the north and west
with significant Li, Cs, Ta and Rb content".
The initial objective for the Phase XII drill program was to focus on converting the Inferred resource lithium bearing
material within the central portion of the Spark deposit at depth. DDH's PL-57, 58, 63 and 64 were all terminated in
pegmatite due to PFS time constraints requiring quick upgrading of some of the existing inferred resource. The
holes will be extended later in the program. With this objective in mind, most May and June drill holes are steeply
dipping (>-65) and designed to infill the Inferred area to a vertical depth of around 300-
320m
. These holes will be
included in the upgraded Measured-Indicated Resource for Spark that will become part of the Prefeasibility Study
(PFS) targeted for completion by the end of 2022.

Currently Frontier has two drill rigs completing in-fill and delineation drilling defining the eastern part of the Spark
deposit and defining the western extensions of the deposit. Several of the initial Phase XII holes that were
terminated in mineralization will be extended. At the time of this press release Frontier had completed over
7,000m
in 22 holes. Laboratory analysis were only complete for the four holes reported.

The original size of the Tanco pegmatite was 57,427,342 tonnes with a maximum thickness of 100m (Stilling, A., Cerny., P., and Vanstone, P.; 2006, The Tanco Pegmatite at Bernic Lake, Manitoba, The
Canadian Mineralogist; Vol. 44 pp. 599-623). The bulk chemical composition for Li
2
O and Ta
2
O

was 0.74% and 366ppm, respectively at Tanco. The Tanco Mine is located in southeastern Manitoba
and was a lithium mineral concentrate producer from 1986 until operations were suspended in 2009 and produced tantalum mineral concentrate until March 2013.

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 (Li
2
O) and inferred resource of 20.87 Mt averaging 1.42 per cent Li
2
O.
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).
