FRONTIER LITHIUM INTERSECTS 126.8M OF

PEGMATITE AVERAGING 1.31% Li2O,

SUDBURY, ON

Dec. 14, 2022

/CNW/ - Frontier Lithium Inc. (TSXV: FL) (FRA: HL2) (OTCQX:

LITOF) ("Frontier" or "the Company") is pleased to announce the results for seven more drill holes

completed during Phase XII drill program on the Spark pegmatite which began in May with two

diamond drill rigs and finished in October of 2022 with

14,641m

in 45 holes. The main objective of

the program was focused on converting 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

When combining Phase XI and Phase XII delineation and infill drilling, the Company completed

15,984m

of drilling in 50 holes in 2022. Highlights from the seven Phase XII diamond drill holes

reported are included below.

Drilled from the south, PL-077-22 was the first of 4 holes designed to define the eastern extent

where the main Spark pegmatite orebody begins to break up into smaller pods separated by

mafic rafts.

"We are pleased with the drilling results from the 2022 Drill Program to date, with the Spark deposit

remaining open in all directions. The focus continues to be at depth and to the west where the grade

and thicknesses of the deposit remain robust." states

Garth Drever

, V.P. Exploration. "Of the

14,641m

drilled during Phase XII, a total of

8,720m

of drill core was cut and submitted for analysis.

15 holes are outstanding and will be disseminated as they are received and pass quality assurance

and control protocols."

The initial objective for the Phase XII drill program was focused on converting the inferred resource

within the Spark deposit to the indicated category in preparation for a pre-feasibility study on the

PAK Lithium Project. The latter half of the program included geotechnical drilling for ground control

and pit design purposes as well as step out drilling to define the eastern and western extents of the

ore body.

the three lithium-cesium-tantalum pegmatites.

Phase XII drill holes completed as well as the channel.

Drill Hole

PL-077-22

Collared in between PL-076-22 and PL-045-19, the hole was designed to define the

pegmatite east of the main body where it begins to break up into smaller pods separated by

mafic rafts. In total, 159m of pegmatite was intersected, most of which was mineralized

(>1% Li2O).

to fill in a gap to convert material and to further define the southern contact of the main ore

body. The intent was to extend the hole and further define smaller pegmatite pods to the

south. A total of 227.3m of pegmatite was intersected with mostly barren pegmatite below 200m..

Due Diligence

All scientific and technical information in this release has been reviewed and approved by

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.
