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.
Highlights
- 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% Li2O
- DDH 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 depth
-
- Includes 14m zone from
89.0m to 103.0m of 2.73% Li2O
- Includes 14m zone from
159.0m to 173.0m of 2.58% Li2O
- Includes 24m zone from
191.0m to 215.0m of 2.52% Li2O
- DDH 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%
Li2O
- PL-071-22 intersected a total of 107.7m of pegmatite averaging 1.40%
Li2O
-
- Includes 5.4m from 242.6 to
248.0m averaging 663 ppm
Ta2O5 and 1.3% Li2O
- PL-073-22 intersected a total of 124.5m of pegmatite averaging 1.38%
Li2O
-
- Includes 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.

Frontier's land tenure and location of the three
lithium-cesium-tantalum pegmatites.

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.
