SUDBURY, ON, Sept. 13, 2021 /CNW/ - Frontier Lithium
Inc. (TSXV: FL) (OTCQX: LITOF) ("Frontier" or "the
Company") is pleased to announce the results of the remaining
three delineation drill hole drilled during The Phase IX drill
program in February and March, 2021 on the Spark
pegmatite. Although drilling was completed on March 19th, 2021, analytical results
have been delayed due mainly to the COVID Pandemic.
Highlights
- The Spark deposit has a large surface exposure, broad
mineralized zones and remains open in all directions, with the most
significant upside at depth and to the southwest;
- Diamond Drill Hole ("DDH") PL-046-21 was collared in mafic
host rock and intersected 320.6 m of
pegmatite averaging 1.68% Li2O (49.7 to 370.3 m);
-
- Includes 94.5m averaging 2.33%
Li2O;
- Includes high grade zone of 27m of 3.41% Li2O;
- The intersection represents a horizontal width of nearly
225 m for the Spark pegmatite
assuming a WSW trend;
- Hole PL-047-19 was collared in pegmatite suggesting a
southwest trend for the pegmatite body.
- Hole PL-049-19 targeted the area between the two main sets
of surface channels from the south and intersected three 15 to
40m pegmatite zones averaging 1.3 to
1.6% Li2O.
"These results confirm continuity of the pegmatite and lithium
grades between holes PL-038-19, PL-039-19 and PL-042-19 and the
surface exposures of the pegmatite," states Garth Drever, V.P. Exploration, "Hole PL-046-19
is a significant step in the process of upgrading Inferred to
Measured and Indicated."
The objectives for the Phase IX drill program in
February-March 2021 were to complete
targets that were not easily accessible in summer months and
considered vital for completing a Pre-feasibility Study. Figure 1
is a location map showing the project area including a compilation
of the Spark Deposit area. Table 1 details the mineralized
intersections in holes PL-046-21, PL-047-21 and PL-049-21 while

Designed to test the
area between PL-038-19 and PL-039-19 drilled from the south and
hole PL-042-19 drilled from the north. The hole was collared in
mafic host rock and intersected mineralized pegmatite from 49.7 m
to 370.3 m (320.6 m averaging 1.68% Li2O) with rare
narrow intervals (5 m or less) of Mafic host rock totalling 16.2 m.
Spodumene consistently occurs throughout the pegmatite. The
intersection included a high grade 27 m intersection of 3.41%
Li2O from 141 to 168 m in LIZ.

Hole PL-046-21 was the first of 4 delineation holes drilled
during Phase IX at Spark. It was stepped back to the south to test
the southern extension of the pegmatite intersected in
geomechanical hole PL-GDH-06-21 (see Press Release dated
June 1, 2021). The hole was collared
in metasediments intersecting a narrow 5.5m zone of LIZ (Lower Intermediate Zone) at
39m before intersecting continuous
pegmatite (predominately LIZ) from 49.7m to 370.3m
averaging 1.68% Li2O. Minor zones of mafic host rock
totaling 16.2m occur from 243 to 288m and again from 335 to 348m these zones are typically less than
1m and up to 5m. Spodumene is ubiquitous throughout the
intersection with laths typically less than 10mm and occasionally
displaying "Jack Straw" textures with lath 2 to 4 cm
over several metres. A 12 m zone
of CIZ (central Intermediate zone) comprised mostly of feldspar and
coarse muscovite which appears to over-print a pre-existing aplite,
occurs from 349 to 361 m. The hole
was terminated at 376.2 m in
metavolcanic. It was not confirmed that the pegmatite was
completely transected.
Hole PL-047-21 was collared 100m
to the west of PL-046-21 and 60m
southsouthwest of hole PL-039-19. It was designed to test the
western extent of the Spark pegmatite and to scissor hole PL-044-19
(most westerly hole drilled from the north). The hole intersected
mostly aplitic pegmatite from 14m to
100m then a mix of pegmatite (10 to
25m intercepts) and host rock before
ending at 298.5m with 78m of mafic hostrock. Enriched lithium zones
rarely exceeded 10m with the highest
grade zone of 2.5% Li2O over 6.6m from 195.9 to 204.8m. Enriched Tantalum occurs in the pegmatite
between 196 and 220m with
11.5m from 209.0 to 220.5m averaging 961 ppm
Ta2O5.
Hole PL-049-21 was collared 30m
southwest of PL-048-21 to test the southern extent of the pegmatite
collared in PL-048-21 (see Press Release dated June 1, 2021) and the area between the holes
PL-041-19 from the north and PL-045-19 from the south. The apparent
mafic-pegmatite contact was intersected near where PL-048-21 was
collared. The pegmatite appears to narrow to 28m (40.3 to 68.3m)
averaging 1.36% Li2O, then 145 metres of predominately
mafic host rock to 213.3 before intersecting a mix of pegmatite
dykes (2 to 40 m wide) and hostrock.
The hole was terminated prematurely at 303.2m with just under 10m of aplite averaging just over 1%
Li2O. As illustrated in Figure 1 the drill hole had not
completely transected the main body of the pegmatite as projected
from surface.
A second geomechanical hole, PL-GDH-07-21, was drilled towards
the south and collared near hole PL-040-19. Only mafic hostrock was
intersected. The hole was drilled to test for pit wall stability
purposes.
Figure 2 is a section displaying the drill hole traces and
lithium concentrations for holes PL-046-21 and PL-048-21 drilled in
2021 along with the 2019 holes and channels confined within a
75m by 350m long section. With the exception of a few
narrow mafic host rock zones, the figure displays the consistency
and continuity of the pegmatite across the width of the Spark
pegmatite. Initial drilling in September will fill-in gaps directly
below the surface channeling and the area between the channels and
hole PL-041-19.
Starting in mid September, Frontier will commence Phase X
drilling at Spark. Objectives will be to complete the geomechanical
drilling and to upgrade the bulk of Inferred resource to Measured
and Indicated as required for the Company's advancing PFS of a
fully-integrated lithium chemical operation.
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 Thunder Bay for
processing and to Mississauga, ON
for quantitative multi-element analysis. AGAT is an ISO accredited
laboratory. The core is stored on site at the Pakeagama Lake
exploration camp.

About PAK Lithium Project
The PAK Lithium 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 covers 65
km of the Avenue length and remains largely unexplored; however,
since 2013 the company has delineated two premium spodumene bearing
lithium deposits (Pak and Spark) located 2.3 km from each other. A
2021 Preliminary Economic Assessment of a fully-integrated lithium
operation utilizing spodumene concentrate generated from the PAK
Lithium Project resource to achieve downstream conversion for
production of battery-quality lithium chemicals (NI 43-101
Technical report titled "PAK Property" by BBA Engineering Ltd.
issued on April 5, 2021) resulted in
a post-tax NPV8% of USD $974M with a
21% IRR. Considerable exploration upside is supported on the PAK
Lithium Project through two other spodumene bearing discoveries;
Bolt pegmatite located between PAK and Spark deposits, as well as
Pennock pegmatite, a further 30 km northwest of PAK within the
Project claims.
