DRILL RESULTS EXTEND THE SPARK
LITHIUM DEPOSIT STRIKE LENGTH BY 80
METRES TO THE WEST AND DISCOVERS A
NEW MINERALIZED ZONE
SUDBURY, ON
,
June 7, 2022
/CNW/ - Frontier Lithium Inc. (TSXV: FL) (FRA: HL2) (OTCQX:
LITOF) ("Frontier" or "the Company")
is pleased to announce the results from the drilling completed
during the Phase XI drill program on the Spark pegmatite. Phase XI drilling was completed in
March
2022
with a total of
1,342.5m
in five holes completed. The Spark pegmatite is one of the
two
delineated premium spodumene-bearing lithium deposits on the PAK Lithium Project.

The lower zone (219 to

of the Spark deposit to the NW.
Between the upper and lower zones, narrower (7.1 and
12.9m
) spodumene-bearing aplitic
zones occur with elevated tantalum (up to 536 ppm Ta
2

"
The Spark deposit is a leading North American lithium-cesium-tantalum pegmatite with significant
size and grades. With the mineralized strike length extended to the west via step-out holes and the
discovery of a new zone, we have confidence that the deposit has high potential to continue to
increase in size. " states
Garth Drever
, V.P. Exploration "We are also beginning to intersect
significant tantalum bearing aplitic zones that are close to the grades seen at the Tanco mine
(1)
at
Bernic Lake in
Manitoba
".
The primary objective for the Phase XI drill program
was to focus on low-ground drilling (best drilled
in the winter months) to define the western limit of the Spark deposit. Instead, our drilling confirmed
that the deposit remains open to the west and we discovered a new zone to the NW that will need
further investigation in the future. Two of five geomechanical holes were completed with three
delineation holes; two of which were collared in muskeg areas. Figure 1 is a location map showing
the project area including Frontier's land tenure and location of the three lithium-cesium-tantalum
pegmatites. It also includes a plan map of the Spark pegmatite with drill hole traces highlighting the
Phase XI drilling completed in February-
March 2022

Total metres drilled

During the winter program, a second drill was mobilized to the project area along with fuel, drill
supplies and additional camp supplies to support Frontier's 2022 summer exploration program, in
part to complete final phase of drilling required to satisfy requirements for the prefeasibility study
(PFS).
(1)
The original size of the Tanco pegmatite was 57,427,342 tonnes with a maximum thickness of 100m (Stilling, A., Cerney., 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 Li2O and Ta2O5 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. Tanco was also a tantalum
mineral concentrate producer until March 2013 when operation of this circuit ceased.
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. T
he
samples were placed in poly sample bags and transported to
Red Lake
by Frontier employees and
then shipped to AGAT Laboratories Ltd. (AGAT) in
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 Projec
t
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 is supported by 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).
