Frontier Lithium reports drilling results and confirms high grades and continuity of the PAK
Lithium Deposit
Highlights:
-DDH PL-028-18 intersected 219.75 m of pegmatite averaging 2.07% Li2O from 62.25 to 282.0 m representing a
horizontal width of over 56 m with a lithium enriched zone (Lower - Upper Intermediate Zone);
-DDH’s PL -028-18 and PL -029-18 confirm and expand the Inferred Resourc e near the base of the current
published Resource Estimate and under the 2018 Pre-Feasibility Open Pit Shell;
- DDH’s PL-030-18 to PL -036-18 better defined the high grade (Upper Intermediate Zone) with intercepts as
high as 51.4m of 4.05% Li2O representing over 35m of horizontal width in DDH PL-035-18;
-Mineralization remains open to depth and along strike to the northwest and south-east whereby the grade
thickness is increasing to the east-south-east (down-plunge).
Sudbury, Ontario, October 16 , 2018 – Frontier Lithium Inc. (TSX.V: FL) (the “Company ) is pleased to
announce the results of a 1,221m Phase VI drill program completed in July 2018. The program was
primarily planned to drill through the Pre -Feasibility Open Pit shell so that the Inferr ed Resources 1 at
depth under the pit shell could be intersected. The secondary objective was to further delineate the high
grade Upper Intermediate Zone (“UIZ”) Reserves close to surface. Two drillholes, PL -028-18 and PL-029-
18 were drilled from the NNE at a steep angle attempting to drill through the bottom of the pegmatite.
Both holes successfully intersected the Inferred Resource at, and near, the base of the pegmatite and
only PL-029-18 may have pierced the bottom.
Six shorter drillholes were used to better define the high grade UIZ at surface. The intersections
determined that the high -grade UIZ portions of the unit are not as continuous as modelled, however,
significant intervals of up to 50m exist of nearly pure spodumene and quartz with consistent grades of
over 4% Li2O.
“We are extremely pleased with the results from this drill program as we successfully hit our targets and
further strengthen the predictability of the deposit”, stated Trevor Walker, President and CEO of the
Company. “With the conclusion of this drilling the Company will commence with an updated mineral
resource calculation. The high -grade thicknesses intersected to date, and mineralization that remains
open to depth and along strike, suggests this pegmatite could be significant ly more robust than is
currently known.”
The assay and collar data for the hole reported is presented in Table I and Table II respectively.
Table I - Diamond Drill Hole Intercepts
1 Inferred Mineral Resources cannot be used in a Pre-Feasibility Study (“PFS”) as a PFS must be supported by mineral reserves.

DDH PL-028-18 Designed to test the continuity of the pegmatite at depth and to upgrade Inferred
Resource to Indicated and Measured. Intersected over 220m of continuous
spodumene mineralization. The drillhole appears to pierce the southern hangingwall of
the pegmatite and not the bottom.

* The intervals (“Width”) in Table I are drill intersection widths. The pegmatite is steeply dipping south -
southwest to sub-vertical. Based on evidence that the orientation of the pegmatite is mostly sub -vertical,
the Horizontal width is representative of the t rue width when the Azimuth of the drillhole is roughly
perpendicular to the strike of the pegmatite which is 110 to 120.
Li2O content in the Li enriched zones is predominantly associated with spodumene.

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, the diamond drill contract specified BTW -sized drill core providing
a 42.0 mm diameter sample. Sample security and chain of cus tody started with the removal of core
from the core tube and boxing of drill core at the drill site. The boxed core remained under the custody
of the drill contractor until it was transported from the drill to the secure on -site Core Shack facility by
either the drill contractor or one of the Company’s designated personnel. At the on -site Core Shack,
core boxes were opened and inspected to ensure correct boxing and labelling of the core by the drill
contractor, photographed and then re -closed. The company geologists geologically logged and marked
the core for sampling before it was photographed. Each core sample was assigned a tag with a unique
identifying number. Sample lengths are typically one meter, but can be less depending on zone
mineralogy and bo undaries. Core marked for sampling was split using a diamond core saw on site and
cut lengthwise into equal halves. Half of the core was sent to an analytical laboratory for quantitative
analysis of select elements. The remaining half of the core is reta ined and replaced in the core box. All
core remains securely in a locked sea-container on site.
All samples were assayed by AGAT Laboratories Ltd. (“AGAT”) , an ISO accredited laboratory in
Mississauga, Ontario. Sample blanks along with tantalum, lithium, rubidium and cesium certified
reference material was routinely inserted into the sample stream in accordance with industry
recommended practices. Field dupl icate samples were also taken in accordance with industry
recommended practices.

About Frontier Lithium Inc.
Frontier’s goal is to become a low-cost, fully integrated lithium and tantalum producer through
development of the PAK lithium deposit in Ontario, Canada. Frontier maintains a tight share structure
with management ownership exceeding 30% of the Company. Exploration work has been conducted
actively since 2013 on the deposit which contains lithium in a rare, high-purity, low-iron spodumene.
The initial target market is the glass-ceramic industry which consumes roughly one-third of global
lithium supply and is currently faced with monopolistic conditions, coupled with major lithium producers
increasingly directing output toward supporting battery manufacture.
Ceramic/glass customers prefer to source technical-grade (low-iron) spodumene concentrate in excess
of 7% lithium oxide (Li2O), if available, to avoid lower grade petalite concentrates, or paying much
higher prices for battery grade lithium compounds.
The PAK lithium deposit remains open in all directions and Company Management is working towards
developing a viable operation. The Company is currently conducting feasibility level programs to
optimize the 2018 Pre-Feasibility Study which positively concluded the economic viability and technical
feasibility of producing lithium concentrates. Frontier’s goal is to first establish a viable technical grade
spodumene concentrate operation. A possible second stage of investment and longer term prospect is
to further process some of PAK’s output to produce the higher purity lithium compounds required for
lithium battery technologies used in the electrification of transportation and electric grid storage
applications.
About the PAK Lithium Project
The PAK Lithium Project lies close to the boundary between two geological sub-provinces of the western
Superior geologic province in northwestern Ontario and hosts a rare metals pegmatite deposit. The
deposit is an LCT (lithium- cesium- tantalum) type pegmatite. These types of pegmatites have been the
principal source of hard rock lithium, tantalum, rubidium and cesium ores mined in the world but there
are comparatively few commercially-viable deposits.
Frontier is actively exploring its 100% owned project which contains the Pakeagama Lake pegmatite. The
PAK deposit has a current Measured and Indicated Resource of 8.5 million tonnes of 1.78% Li 2O and 101
ppm Ta2O5 and an Inferred Resource of 1.92 million tonnes of 2.01% Li2O and 97 ppm Ta2O5 which has a
technical/ceramic grade spodumene with low inherent iron (below 0.1% Fe2O3). The deposit has
adjacent zones that are enriched in tantalum and rubidium.
The deposit now has a known 500m strike length with an estimated true width varying from 10m to
125m with a sub-vertical orientation. The resource remains open to depth and along strike to the
northwest and southeast.
