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 19
th
, 2021, analytical results have been delayed due mainly to the COVID Pandemic.
Spark Drilling Phase IX Results (CNW Group/Frontier Lithium Inc.)
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% Li
2
O (49.7 to
370.3
m
);
Includes
94.5m
averaging 2.33% Li
2
O;
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% Li
2
O.
"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 Table 2 is a summary of all the Phase IX drill holes.

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%
Li
2
O. 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% Li
2
O 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 Ta

O

.
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% Li
2
O, 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% Li
2
O. 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
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 Frontier Lithium
Frontier Lithium (TSX.V: FL) (OTCQX: LITOF) (FSE: HL2) is an emerging pure play lithium company with the largest land position in the Electric Avenue, an
emerging premium lithium mineral district located in the Great Lakes region of northern
Ontario
. The company maintains 100% ownership in 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 has
significant upside exploration potential. Frontier is a pre-production business that is targeting the manufacturing of battery quality lithium hydroxide in the Great
Lakes Region to support electric vehicle and battery supply chains in
North America
. Frontier maintains a tight share structure with management ownership
approximately 25% of the Company.
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.
