FRONTIER DRILLS 405 METRES OF 1.5% Li2O FROM PHASE X DRILLING AT SPARK

Canada NewsWire

SUDBURY, ON, Feb. 16, 2022 /CNW/ – Frontier Lithium Inc. (TSXV: FL) (OTCQX: LITOF) (“Frontier” or “the Company”) is pleased to announce the results of the three remaining drill holes and supplemental channels completed during the Phase X drill program on the Spark pegmatite, the second delineated premium spodumene-bearing lithium deposit on the PAK Lithium Project.

Highlights:

  • Hole PL-050-21 tested depth and width of the main body of the Spark pegmatite, included a total of 405m of mineralized pegmatite averaging 1.5% Li2O;
    • Apparent width of 143m to a vertical depth extent of at least 392m;
  • Hole PL-051-21 intersected a total of 264m of pegmatite averaging 1.6% Li2O;
    • Included a 60m section from 216m to 276m averaging 2.5% Li2O

“We are extremely pleased with these results as they confirm continuity in quality and grade of the Spark deposit and they continue to increase the size of the resource,” states Garth Drever, V.P. Exploration and added “With the grade-thickness persisting at depth, the Spark deposit contains significant potential for growth.”

The objectives for the Phase X drill program in September-October 2021 were to complete drill targets considered vital for completing a Pre-Feasibility Study (PFS). Figure 1 is a location map showing the project area including Frontier’s land tenure, geology, and location of the three pegmatites, PAK, Bolt and Spark while Figure 2 is a plan map of the Spark pegmatite with drill hole traces highlighting the last three holes and two channels being reported. Table 1 details the mineralized intersections in holes PL-050-21 to PL-052-21 while Table 2 is a summary of all the Phase X drill holes. Table 3 details the mineralized intervals of the channels cut at Spark and Table 4 is a summary of the channels.

DDH PL-050-21

Planned to test continuity of the pegmatite between PL-041-19 and PL-042-19 below channels 33-35 and at a steeper dip (-70°). The hole intersected primarily mineralized pegmatite from surface to 417m representing a horizontal and vertical distance of 143 and 392 m respectively. Minor mafic metavolcanics up to 5m wide occur with one 11.5 m mafic zone from 154.7 to 165.3m. The total pegmatite intersected was 405m averaging 1.5% Li2O.

Two channels were cut; CH-48 was cut 30m WSW of CH-44 along the most southwestern portion of the exposed pegmatite and CH-50 was cut 45m WSW of CH-33 (broken into two segments). The entire 15m of CH-48 averaged 1.75% Li2O while the initial 10m of CH-50 averaged 1.28% Li2O and the last 22m was higher at 1.85% Li2O.

* Pegmatite section from 10 to 17m was not cut because of overburden

Drill holes PL-050-21 and PL-051-21 were planned to fill-in between existing drill holes and to test to the southern continuity of the mineralized pegmatite’s main body currently defined. PL-050-21 was collared in the pegmatite near PL-GDH-08-21 which intersected 95m of mineralized pegmatite to the north. PL-050-21 was steepened to -70°. Aside from a few thin mafic zones, a total of 405m of pegmatite averaging 1.5% Li2O was intersected. The mineralized pegmatite intersected represents a horizontal width of 143m and a vertical depth of 392m. PL-051-21, drilled at -60° set-up between PL-042-19 and PL-044-19 and to “scissor” PL-039-19, intersected predominately pegmatite with intervals of mafic metavolcanics a few metres to 25m wide from surface to 302m. The total pegmatite intersected between surface and 302m downhole includes 264m averaging 1.6% Li2O.

Hole PL-052-21 was drilled to test between holes PL-041-19 and PL-043-19 and east of Channels 37 and 38 (Figure 2). The hole intersected three main mineralized pegmatite zones 21 to 72m wide correlating well with zones intersected in PL-043-19 to the east. Li2O grades are slightly lower between 0.8% Li2O and 1.2% Li2O. Minor metavolcanics occur within the pegmatitic zones.

During the drill program, two addition channels were cut and sampled on the Spark outcrop surface (Table 4 and Figures 2 and 3). Channel CH-48 was cut along the farthest southwest exposure at the top of a ridge above the collar for DDH PL-039-19. The 15m channel of pegmatite averaged 1.75% Li2O. The second channel, CH-50 located to the north of CH-48 and between holes PL-050-21 and PL-051-21 was cut in two segments with a 7m gap between 10m and 17m due to overburden. The initial 10m of aplite-pegmatite averaged 1.28% Li2O and the last 22m of pegmatite was higher at 1.85% 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 Frontier employees and then shipped to AGAT Laboratories Ltd. (AGAT) in 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 that is targeting to become a manufacturer of battery-quality lithium materials to support electric vehicle and battery supply chains in North America. Frontier owns the PAK Lithium Project which contains one of North America’s highest-grade, large-tonnage hard-rock lithium resources in the form of a rare low-iron spodumene. The project continues to have significant exploration upside with potential to increase the lithium resource. The Company is a pure-play lithium development opportunity with the largest land position in the Electric Avenue, a premium lithium mineral district located in Northern Ontario.

About PAK Lithium Project

The PAK Lithium Project contains a tier one lithium resource in North America and is one of the global top three premium resources by quality. A 2021 preliminary economic assessment (National Instrument 43-101 technical report titled “Pak Property” by BBA Engineering Ltd., issued on April 5, 2021) delivered a fully integrated lithium operation from the resource to achieve downstream conversion plan for production of battery-quality lithium salts. The study resulted in an after-tax net present value (discounted at 8 per cent) of $974-million (U.S.) with a 21-per-cent internal rate of return. The Project encompasses 26,774 hectares at the south end of Ontario’s Electric Avenue, the largest land package hosting premium lithium-bearing pegmatites in Ontario. The Project is supported by a measured and indicated resource of 10.49 million tonnes (Mt) averaging 1.78 per cent lithium oxide (Li2O) and inferred resource of 18.48 Mt averaging 1.45 per cent Li2O.The Project covers 65 kilometres of the Electric Avenue’s length 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. Considerable exploration upside is supported on the PAK Lithium Project through two other spodumene-bearing discoveries: the Bolt pegmatite (located between the PAK and Spark deposits), as well as the Pennock pegmatite (30 kilometres northwest of PAK Deposit within the project claims).
