Frontier Lithium Intersects 338m Of Pegmatite Averaging 1.64% Li2o, Including A 68m Zone Of 2.00% Li2o

• 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.
• DDH PL-074-22 intersected 35.8m of pegmatite averaging 2.05% Li₂O. Collared in the mafic volcanic host rock 50m west of PL-044-22, the hole was designed to define the western extent where the main Spark pegmatite orebody begins to break up into smaller pods separated by mafic rafts.
• Includes 10.2m from 89.8m to 100.0m averaging 4.27% Li₂O.
• DDH PL-075-22 intersected 83.2m of pegmatite averaging 1.66% Li₂O. Collared in the mafic volcanic host rock 15m west of PL-074-22, the hole was fanned out further to the west to define the western extent where the main Spark pegmatite orebody begins to break up and narrows into smaller pods.
• Includes 10.5m from 111.7m to 122.2m averaging 2.62% Li₂O.
• Includes 5.8m from 203.3m to 209.1m averaging 2.37% Li₂O.
• Includes 8.3m from 220.0m to 228.4m averaging 2.74% Li₂O.
• DDH PL-076-22 intersected 338.0m of pegmatite averaging 1.64% Li₂O. Collared in the mafic volcanic host rock in the same location as PL-072-22, the hole was designed to convert inferred material at depth as well as define a mafic raft on the eastern extent of the main orebody. The hole had to be abandoned in high grade pegmatite due to blockage downhole.
• Includes 14.4m from 184.6m to 199.0m averaging 2.14% Li₂O.
• Includes 68.0m from 206.0m to 274.0m averaging 2.00% Li₂O.
• Includes 12.0m from 367.0m to 379.0m averaging 2.25% Li₂O.
• Includes 18.0m from 420.0 to 438.0m averaging 1.89% Li₂O at the end of the hole.
• DDH PL-079-22 intersected 107.0m of pegmatite averaging 1.37% Li₂O. Collared in the mafic volcanic host rock 35m west of PL-075-22, the hole was stepped out to define and cutoff the western extent of the Spark pegmatite. The results have extended the southern pod of the pegmatite further to the west and remains open with a strike length of 500m.
• Includes 27.9m from 158.0m to 185.9m averaging 1.90% Li₂O.
• Includes 7.6m from 202.4m to 210.0m averaging 1.99% Li₂O.
• Includes 9.4m from 238.0m to 247.5m averaging 2.12% Li₂O.
• Channel CH-51 totaling 21m in length averaged 1.92% Li₂O. The channel was cut on the eastern end of the main Spark pegmatite between CH-35 and CH-38 to confirm grade continuity at surface in an area where the terrain made it difficult to mobilize a diamond drill.
• Includes 3.0m from 0.0 to 3.0m averaging 2.46 Li₂O.
• Includes 7.0m from 7.0 to 14.0m averaging 2.34 Li₂O.

"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.

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.

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.

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.
