FRONTIER LITHIUM INTERSECTS 126.8M OF PEGMATITE AVERAGING 1.31% Li2O, INCLUDING A 11M ZONE OF 1.79% Li2O and 459ppm Ta2O5 AND ANNOUNCES NEW STOCK OPTION PLAN AND GRANT OF OPTIONS

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.
• DDH PL-077-22 intersected 126.8m of pegmatite from 56.9m to 183.7m averaging 1.31% Li2O. 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.
• Includes two narrow lithium and tantalum enriched zones at depth including 11.1m from 260.2 to 271.3m averaging 1.79% Li2O and 459 ppm Ta2O5 and 13.5m from 414.5 to 428.0m averaging 1.01% Li2O and 194 ppm Ta2O5.
• DDH PL-078-22 intersected 104.9m of pegmatite from 120.4 to 225.3m averaging 1.58% Li2O and a second 33.5m pegmatite zone from 246.7 to 280.2m averaging 1.63% Li2O. Collared in the mafic volcanic host rock 24m west of PL-040-19, the hole designed to define the eastern extent where the main Spark pegmatite orebody begins to break up into smaller pods separated by mafic rafts.
• Includes 35m from 149.0 to 184.0m averaging 2.39% Li2O.
• Includes 24.3m from 255.5m to 259.8m averaging 2.04% Li2O.

"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.

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.

New Stock Option Plan and Grant of Stock Options

The Company also announces that it has adopted a new 10% rolling stock option plan (the "New Stock Option Plan"). The New Stock Option Plan has been approved by the board of directors of the Company, the shareholders of the Company at the annual general meeting of shareholders on October 3, 2022, and is subject to approval by the TSX Venture Exchange ("TSXV").

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 premium lithium mineral district located in Ontario's Great Lakes region.

The PAK lithium project contains one of North America's highest-grade lithium resources. The project encompasses close to 27,000 hectares 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. Exploration is continuing 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). A 2021 preliminary economic assessment (National Instrument 43-101 technical report titled "NI 43-101 Technical Report, Pak Property, PAK, Red Lake Mining District, Ontario, Canada" by BBA E&C Inc., with an effective date of April 5, 2021) delivered a fully integrated lithium operation, including the mine and mill and the conversion plant for production of battery-quality lithium salts.
