/CNW/ -
Frontier Lithium Inc. (TSX.V: FL) (the "Company" or
"Frontier")
is pleased to report a Canadian National Instrument (N.I.) 43-101 maiden mineral
resource estimate for the Spark deposit, located within the "Electric Avenue" in northwestern,
Ontario
. The resource estimation has been prepared by WSP Canada Inc. (TSX: WSP). WSP is
one of the largest engineering firms in
Canada
and has a mining division maintaining independent
consulting geologists and engineers. Table 1 is a summary of the mineral resource estimate.
"We are pleased to have been able to put out this Maiden Lithium Mineral Resource estimate less
than 14 months after the 'discovery' of the Spark pegmatite", commented
Trevor Walker
, President
and CEO of Frontier Lithium. "Located in
Ontario's
premium lithium jurisdiction, the Electric Avenue,
this second deposit on the PAK Lithium project supports our exploration model and highlights the
resource upside potential for any required expansion in the future. The management is focused
on Phase I Development plans under an Advanced Exploration program to confirm the Project's
economic viability through the construction and operation of a Demonstration Concentrator Plant"
added Walker.

Mineral Resource Estimate Notes
1.
Mineral Resources were prepared in accordance with NI 43-101 and the CIM Definition Standards (2014). Mineral resources that are not mineral reserves do not have
demonstrated economic viability. This estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical,
marketing, or other relevant issues.
2.
Open pit Mineral Resources are reported at a cut-off grade of 0.65 % Li2O that is based on a spodumene concentrate prices of US$700/tonne and an exchange rate of 1.3.
3.
Appropriate mining costs, processing costs, metal recoveries, and inter ramp pit slope angles were used by WSP to generate the pit shell.
4.
Rounding may result in apparent summation differences between tonnes, grade, and contained metal content.
5.
Tonnage and grade measurements are in metric units.
6.
Contributing assay composites were capped at 3.55% Li
2
O.
7.
A bulk density factor of 2.718 was applied to the pegmatite based on 241 measurements.
Modeling was performed using GEOVIA Surpac® 2019 software with grades estimated using ordinary kriging (OK) interpolation methodology. Samples were composited at 1.0
metre down hole and composites were capped at 3.55% Li
2
O. Block grades were estimated on a multi pass basis with a minimum and maximum number of composites required
for each estimation pass. Block size is 2 metre by 2 metre (y) by 2 metre (z).
Additional information about the Mineral Resource modeling methodology will be documented in the upcoming NI 43-101 technical report (the "Technical Report").
The Spark pegmatite was initially discovered in September 2018. Channel sampling was initiated
immediately after discovery whereby drilling began in
February 2019
and was completed by
August
2019
. Figure 1 shows the location of the Spark pegmatite with the location of all 12 channel cuts
and the drill hole traces of all 9 drill holes. The results from the channels and drilling has been
reported in Press Releases dated
January 17
,
April 9
,
May 30
,
September 24, 2019
and

,
2020. A total of 2499.5 metres of drilling in 9 holes and 288.4 metres of channel cuts in 12 channels
were used in the Resource Estimate. The immediate area has been mapped with 1.9 hectares of
exposed pegmatite as shown on Figure 1.

Pegmatite
Geological logging of channels and drill core combined with multi-element geochemistry indicates a
high degree of compositional homogeneity throughout the deposit. The pegmatite consists primarily
of sodic aplite which 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. The coarser grained zones are
similar in appearance and composition to the LIZ (Lower Intermediate Zone) at the PAK deposit 2.3
km to the south west.
Figure 2 is a 3D rendering of the block model and required pit shell of the Spark pegmatite. The
deposit's current dimensions are roughly
300m
in length by 50 to over
100m
in width. Drilling has
extended the deposit to at least
250m
in depth. It remains open in all directions.

Polished thin sections of drillcore were selected specifically for EMP (electron microprobe) analysis
of spodumene during both drill programs. The analysis was completed in early
November 2019
at
QFIR (Queen's Facility for Isotope Research) at Queen's University in
Kingston
, Ontario.

Due Diligence
All scientific and technical information in this release has been reviewed and approved by
Todd
McCracken
, P.Geo., Manager - Mining for WSP, the qualified person (QP) and
Garth Drever
,
P.Geo., VP Exploration for Frontier Lithium Inc. 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.

About the PAK Lithium Project
The PAK Lithium Project encompasses 26,774 hectares at the south end of
Ontario's
Electric
Avenue, which is the largest land package hosting lithium bearing pegmatites in
Ontario
. The Project
remains largely unexplored; however, it does host two premium spodumene bearing lithium deposits
located only 2.3 km of each other. Recently, Frontier confirmed the presence of spodumene with the
Pennock Lake pegmatite occurrence a further 30km along Frontier's PAK Lithium Project.
The PAK deposit has a mineral reserve in proven and probable category of 5.77 MT averaging 2%
