SUDBURY, ON, Jan. 7, 2020
/CNW/ - Frontier Lithium Inc. (TSX.V: FL) (the
"Company) is pleased to announce the remaining results of
their second Phase of drilling on the Spark Pegmatite.
Frontier completed four diamond drill holes totaling 1,159.5 m in July-August
2019 (Table 1). During the drill program an additional
4 channels totaling 52 m (Table 2)
were cut and most of the exposed outcrop surface in the immediate
area of the pegmatite was mapped. An analysis of the results from
the drill program and assay results from the first two drill holes
are included in a Press Release dated September 24th, 2019 and will not be
repeated in this Press Release.
"Supported by preliminary modelling, we strongly believe in the
potential for economic viability of the Spark pegmatite." commented
Garth Drever, Vice President of
Exploration. "The deposit remains open to the west and has
maintained consistency in both grade and width with depth. The
physical data collected through surface and remote mapping at PAK
and Spark has proven invaluable as a first-pass exploration tool to
evaluating the potential of our mining claims on the Electric
Avenue."

Table 3 shows a summary of the assay results of holes PL-044-19
and PL-045-19.
Hole PL-044-19 was designed to step out 50m to 75m to test
the extension of the pegmatite to the west of hole PL-039-19.
Three significant pegmatite zones were intersected with an upper
75m intercept averaging 1.4%
Li2O. The two lower zones of 12 and 27.4m consist of slightly lower grade
spodumene-bearing aplite averaging 0.74% and 0.87%
Li2O.

Figures 2 and 3 are Sections for holes PL-044-19 and PL-045-19
respectively showing Li2O content as histogram plots
along the drill hole and channel traces. The section in
Figure 2 was extended to include hole PL-039-19. Although
only scattered remnants of pegmatite were noted on surface during
mapping and prospecting it is apparent that there are two
significant lobes of the pegmatite that extend upward to the
surface beneath the overburden.

The final hole of the program, PL-045-19, extended hole
PL-037-19 which had been abandon. Hole PL-045-19 intersected
a 17.1m zone of spodumene-bearing
aplite averaging 0.78% Li2O before intersecting a 144.2m zone of predominately pegmatite from 70.8
to 215m averaging 1.4%
Li2O. A 15m zone
from 130 to 145m averages 2.47%
Li2O. Anomalous Ta, Sn and Rb occurs over an
11.2m zone from 175 to 186.2m averaging 659 ppm
Ta2O5, 520 ppm SnO2 and 0.88%
Rb2O. An analogous zone of enriched Ta is present above
in Channel 37 from 63.2 to 69.4m
(6.2m) averaging 615 ppm
Ta2O5 (see Press Release January 17, 2019). Figure 3 shows the
section of hole PL-045-19 with Channels 37 and 38 plotted at
surface. Both Li2O and Ta2O5
are plotted along the trace of the drill holes and channels.

During the summer drill program an additional 52m of channels (Channels 41 to 43) were cut to
complete the section between Channel 38 and start of Channel 40 and
to sample across the western most exposed lobe of the pegmatite
(Channel 44). These channels are highlighted on Figure 1 and
displayed in Figure 4 in a section including hole PL-040-19 and
PL-043-19. Assay results are summarized in Table 4. All
channels were logged as spodumene-bearing Na-aplite with consistent
grades between 1.5 and 1.77% Li2O. The aplite is
typically fine to medium grained, light grey to greenish grey
locally with coarser zonations consisting of megacrystic feldspar,
fine to coarse-grained light grey to white spodumene laths, grey
quartz and variable amounts of muscovite.

During the summer drill program much of what was previously
described as metavolcanics rock has been subdivided into
metasedimentary units which are now recognized to be intercalated
within the metavolcanics sequences.
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
halve 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, ON for quantitative multi-element
analysis. AGAT is an ISO accredited laboratory. All
petrographic sample preparation and electron microprobe (EMP)
analysis was completed at the Queen's Facility for Isotope Research
(QFIR) at Queen's University in Kingston,
Ontario under the direct supervision of Dr. Steve Beyer. The core is stored on site at the
Pakeagama Lake exploration camp.
