SUDBURY, ON, Sept. 20, 2022 /CNW/ - Frontier Lithium Inc. ( TSXV: FL) (FRA: HL2) (OTCQX: LITOF) ("Frontier" or "the Company") is pleased to announce the results for five additional drill holes completed during the Phase XII drill program on the Spark pegmatite which began in May 2022 and is currently in progress. The initial drill holes were designed to convert 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.

Phase XII delineation and infill drilling with two drill rigs is currently being conducted, whereby, the Company has completed 11,150m of drilling in 34 holes as of September 11, 2022. Analysis from 5 of the holes have been received and reported herein.DDH PL-062-22 Intersected a total of 180.8m of pegmatite averaging 1.55% Li2O with thin sheets of mafic rafts within the pegmatite as expected. Collared north of the Spark Pegmatite in mafic volcanic, hole was drilled to convert inferred material at depth and to provide a northern contact of the Spark Pegmatite. Hole was terminated in pegmatite due to time constraints and will extended later in the program.Includes 16.9m from 178.0m to 194.9m of 2.19% Li2ODDH PL-066-22 intersected 338.0m of continuous pegmatite averaging 1.79% Li2O. Collared in pegmatite on the southern end of the Spark orebody, the hole was drilled to convert inferred material at depthIncludes 14m zone from 89.0m to 103.0m of 2.73% Li2OIncludes 14m zone from 159.0m to 173.0m of 2.58% Li2OIncludes 24m zone from 191.0m to 215.0m of 2.52% Li2ODDH PL-070-22, PL-071-22 and PL-073-22 were collared proximal to each other and fanned out to test both the northern upper and southern lower contacts with the mafic host rock. As expected, they intersected diminishing proportions of pegmatite from west to east with an increase in mafic rafts towards the east.PL-070-22 intersected a total of 181.1m of pegmatite averaging 1.53% Li2OPL-071-22 intersected a total of 107.7m of pegmatite averaging 1.40% Li2OIncludes 5.4m from 242.6 to 248.0m averaging 663 ppm Ta2O5 and 1.3% Li2OPL-073-22 intersected a total of 124.5m of pegmatite averaging 1.38% Li2OIncludes 16.0m from 92.2 to 108.1 averaging 521 ppm Ta2O5 and 1.02% Li2O
"We are extremely pleased with the drilling results to date." states Garth Drever, V.P. Exploration. "The infill-drilling continues to be predictable, the pegmatite remains open in all directions and zones of elevated tantalum and cesium along with lithium are being delineated."
The initial objective for the Phase XII drill program was to focus on converting the inferred resource within the central portion of the Spark deposit at depth. DDH's PL-062-22 was terminated in pegmatite and PL-066-22 was ended in mafic volcanics due to PFS time constraints requiring quick turn-around of analysis. With one month of drilling remaining in the current program, Frontier will focus on defining the limits of the pegmatite and deepening many of the initial holes that had been terminated earlier in the program.

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.
