Frontier Lithium Expands Eastern Extension of the PAK Deposit
Intersecting a Low-Iron Intercept of 2.47% Li2O over 119 metres
HIGHLIGHTS
• DDH PL-027-17 intersected 118.9 m of pegmatite averaging 2.47% Li2O from 237.3 to 356.0 m
representing a true width of 55.7 m with a low-iron lithium enriched zone
(Lower - Upper Intermediate Zone)
• DDH PL-027-17 includes 3.30% Li2O over 53 m from 287 to 340 m representing a true width
of 25.0 m (Figure 1);
• DDH PL-027-17 includes a high-grade Lithium zone (Upper Intermediate Zone) of 14 m
averaging 4.41% Li2O from 290.0 to 304.0 m representing a true width of 6.6 m;
• Based on this recent drill result, a Pre-Feasibility Study (PFS) originally scheduled to be completed
by mid-December will now include an updated resource estimate and an
underground component which will be released in early 2018, and;
• Mineralization remains open to depth and along strike to the northwest and the grade thickness is
increasing to the east-south-east (down-plunge).
Sudbury, Ontario, December 6, 2017 – Frontier Lithium Inc. (TSX.V: FL) (the “Company) is pleased
to announce the results of an exploration hole that was drilled after the completion of the 2017 geotechnical/
geomechanical drill program. Diamond drill hole PL-27-17 was designed to step back and test the width and
attitude of the pegmatite zone from the footwall (metasediment side) through to the hanging wall (granite side)
on the down-plunge extension of the deposit. The assay and collar data for the hole reported is presented in
Table I and Table II respectively.

Table II - Collar Locations for Diamond Drill Hole
(1) The intervals in Table I are drill intersection widths. The “true width” is based on overwhelming evidence that the orientation of the pegmatite is sub-vertical.
(2) Li2O content in the Li enriched zones is predominantly associated with spodumene.

Due Diligence
All scientifi c and technical information in this release has been reviewed and approved by Garth Drever,
P.Geo., the qualifi ed person (QP) under the defi nitions established by National Instrument 43-101. Under
Frontier’s QA/QC procedures, the diamond drill contract specifi ed NQ-sized drill core providing a 47.6 mm
diameter sample. Drill hole PL-027-17 was oriented perpendicular to the strike of the pegmatite and drilled
continuously across it. Sample security and chain of custody 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 boundaries. 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 retained 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 certifi ed 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.

“We are extremely pleased with the results from this drill hole
as it lies down-plunge of the open-pit shell currently being
used in the PFS study underway on the deposit and displays
that the grade is persisting with depth with true widths of up
to 55 metres with little in the way of contaminants or potential
mining dilution”, commented Garth Drever, VP Exploration
of Frontier Lithium. “These material facts have imposed an
update to the resource model and also has prompted Frontier
to include a low-cost, bulk underground mining component
to the PFS, all of which is underway and expected to be
announced now in early 2018. The predictability, along
with the high-grade thicknesses intersected to date, and
mineralization that remains open to depth and along strike,
suggests this pegmatite could be signifi cantly more robust
than is currently known.” Frontier is currently planning for
2018 exploratory diamond drilling to further increase the
resource size.

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. CAD $7 million of work has been conducted from 2013 to 2017 on
the deposit which boasts its 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 a pre-feasibility study to assess the
economic viability and technical feasibility of producing lithium concentrates. Frontier’s goal is to fi rst 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 electrifi cation 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 7.89 million tonnes of 1.73% Li2O equivalent (eq.)
or 1.58% Li20 and 104 ppm Ta2O5 and an Inferred Resource of 295,600 tonnes of 1.35% Li2O eq. or 1.20%
Li2O and 103 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.
