Frontier Drills 405 Metres of 1.5% Li2O from Phase X Drilling at Spark

Drill Results

FRONTIER DRILLS 405 METRES OF 1.5% Li2O

FROM PHASE X DRILLING AT SPARK

SUDBURY, ON

,

Feb. 16, 2022

/CNW/ - Frontier Lithium Inc. (TSXV: FL) (OTCQX: LITOF)

("Frontier" or "the Company") is pleased to announce the results of the three remaining drill holes

and supplemental channels completed during the Phase X drill program on the Spark pegmatite, the

second delineated premium spodumene-bearing lithium deposit on the PAK Lithium Project.

Highlights:

Hole PL-050-21 tested depth and width of the main body of the Spark pegmatite,

included a total of

405m

of mineralized pegmatite averaging 1.5% Li

2

O;

Apparent width of

143m

to a vertical depth extent of at least

392m

;

Hole PL-051-21 intersected a total of

264m

of pegmatite averaging 1.6% Li

2

O;

Included a

60m

section from

216m

to

276m

averaging 2.5% Li

2

O

"We are extremely pleased with these results as they confirm continuity in quality and grade of the

Spark deposit and they continue to increase the size of the resource," states

Garth Drever

, V.P.

Exploration and added "With the grade-thickness persisting at depth, the Spark deposit contains

significant potential for growth."

The objectives for the Phase X drill program in September-

October 2021

were to complete drill

targets considered vital for completing a Pre-Feasibility Study (PFS). Figure 1 is a location map

showing the project area including Frontier's land tenure, geology, and location of the three

pegmatites, PAK, Bolt and Spark while Figure 2 is a plan map of the Spark pegmatite with drill hole

traces highlighting the last three holes and two channels being reported. Table 1 details the

mineralized intersections in holes PL-050-21 to PL-052-21 while Table 2 is a summary of all the

Phase X drill holes. Table 3 details the mineralized intervals of the channels cut at Spark and Table 4

is a summary of the channels.

Planned to test continuity of the pegmatite between PL-041-19 and PL-042-19 below channels 33-35 and at a steeper dip (-70°). The hole intersected

primarily mineralized pegmatite from surface to 417m representing a horizontal and vertical distance of 143 and 392 m respectively. Minor mafic

metavolcanics up to 5m wide occur with one 11.5 m mafic zone from 154.7 to 165.3m. The total pegmatite intersected was 405m averaging 1.5% Li

* Pegmatite section from 10 to 17m was not cut because of overburden

Drill holes PL-050-21 and PL-051-21 were planned to fill-in between existing drill holes and to test to

the southern continuity of the mineralized pegmatite's main body currently defined. PL-050-21 was

collared in the pegmatite near PL-GDH-08-21 which intersected

95m

of mineralized pegmatite to the

north. PL-050-21 was steepened to -70°. Aside from a few thin mafic zones, a total of

405m

of

pegmatite averaging 1.5% Li

2

O was intersected. The mineralized pegmatite intersected represents

a horizontal width of

143m

and a vertical depth of

392m

. PL-051-21, drilled at -60° set-up between

PL-042-19 and PL-044-19 and to "scissor" PL-039-19, intersected predominately pegmatite with

intervals of mafic metavolcanics a few metres to

25m

wide from surface to

302m

. The total

pegmatite intersected between surface and

302m

downhole includes

264m

averaging 1.6% Li

2

O.

Hole PL-052-21 was drilled to test between holes PL-041-19 and PL-043-19 and east of Channels

37 and 38 (Figure 2). The hole intersected three main mineralized pegmatite zones 21 to

72m

wide

correlating well with zones intersected in PL-043-19 to the east. Li

2

O grades are slightly lower

between 0.8% Li2O and 1.2% Li

2

O. Minor metavolcanics occur within the pegmatitic zones.

During the drill program, two addition channels were cut and sampled on the Spark outcrop surface

(Table 4 and Figures 2 and 3). Channel CH-48 was cut along the farthest southwest exposure at the

top of a ridge above the collar for DDH PL-039-19. The

15m

channel of pegmatite averaged 1.75%

Li

2

O. The second channel, CH-50 located to the north of CH-48 and between holes PL-050-21 and

PL-051-21 was cut in two segments with a

7m

gap between

10m

and

17m

due to overburden. The

initial

10m

of aplite-pegmatite averaged 1.28% Li

2

O and the last

22m

of pegmatite was higher at

1.85% Li

2

O.

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 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 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. The Company is

a pure-play lithium development opportunity with the largest land position in the Electric Avenue, a

premium lithium mineral district located in

Northern Ontario

.

About PAK Lithium Project

The PAK Lithium Project contains a tier one lithium resource in

North America

and is one of the

global top three premium resources by quality. A 2021 preliminary economic assessment (National

Instrument 43-101 technical report titled "Pak Property" by BBA Engineering Ltd., 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 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 is

supported by a measured and indicated resource of 10.49 million tonnes (Mt) averaging 1.78 per

cent lithium oxide (Li

2

O) and inferred resource of 18.48 Mt averaging 1.45 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 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 (30 kilometres northwest

of PAK Deposit within the project claims).
