/CNW/ – Frontier Lithium Inc. (TSXV: FL) (FRA: HL2) (OTCQX: LITOF) (“Frontier” or “the Company”) is pleased to announce the results for four additional drill holes and 1 channel completed during the 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. Analysis from 4 of the Phase XII diamond drill holes and channel are reported herein.

“We’re pleased with the progress made at our PAK Lithium Project this year as the drilling season comes to an end.” states

Garth Drever

, V.P. Exploration. “We’re confident we’ve converted the required tonnage on the Spark pegmatite for our upcoming PFS and have also added to the total resource with new inferred material to the west and at depth.”

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.

Figure 1 is a location map showing the project area including Frontier’s land tenure and location of the three lithium-cesium-tantalum pegmatites.

Figure 2 is a plan view showing all drilling with analytical data completed to date with emphasis on drill hole traces and channel reported in this release.

Table 1 details the drill holes and channel with mineralized intersections while Table 2 summarizes all Phase XII drill holes completed as well as the channel.

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 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 new premium lithium mineral district located in

Ontario’s

Great Lakes region.

About PAK Lithium Project

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 ongoing 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.
