Frontier Lithium Intersects 154.3m of Pegmatite Averaging 1.69% Li2o, Including a 26m Zone of 2.15% Li2o

2023-01-10 05:35:48

SUDBURY, ON, Jan. 10, 2023 /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.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

  • 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-086-22 intersected 154.3m of pegmatite from 3.7m to 158.0m averaging 1.69% Li2O. Collared near the centre of the main Spark pegmatite, hole was drilled to provide a southern contact where there was a gap in the model.

    • Including 26.0m from 70.0m to 96.0m averaging 2.15% Li2O
    • Including 12.0m from 114.0m to 126.0m averaging 2.36% Li2O

  • DDH PL-088-22 intersected 126.5m of pegmatite from 0.5m to 127.0m averaging 1.94% Li2O and a second 9.8m pegmatite zone from 157.3m to 167.0m averaging 2.01% Li2O. Collared 30m to the SW of PL-086-22 on the main Spark pegmatite, hole was also drilled to provide a southern contact where there was a gap in the model further to the west.

    • Includes 14.1m from 4.4m to 18.5m averaging 2.13% Li2O.
    • Includes 10.0m from 30.5m to 40.5m averaging 2.21% Li2O.
    • Includes 21.8m from 79.2m to 101.0m averaging 2.58% Li2O.

“We are definitely pleased with the infill drilling to date as it suggests that the Spark resource is present in the expected locations with the expected grades, and that the resource estimate is reliable and potentially larger than previously thought.” states Garth Drever, VP Exploration “The delineation drilling has successfully added additional pegmatite to the west while pinching out to the east. We look forward to focusing on adding inferred resource to the west and at depth which remain open.”

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 (PFS) 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.

Drill Hole

PL-085-22

Collared on the main Spark pegmatite in between PL-057-22 and PL-082-22, hole was designed to provide a
northern contact where there was a gap in the model.  A total of 86m of pegmatite was intersected with most of
the material near the end of the hole falling below the cut off grade of 0.65% Li2O.

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 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 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.
