Frontier Lithium makes a new discovery on the PAK Lithium Project.
Highlights:
- A new LCT Pegmatite showing, herein called the Spark Pegmatite, was discovered 2.3 km northwest
of the PAK Lithium Deposit;
-The surface area of the exposed pegmatite is 3.5 hectares with widths greater than 100m and a strike
length of more than 300m. All indications suggest the pegmatite has a sub-vertical orientation;
- A total of 236.4 m of channels have been cut and sampled. Channel 33, representing 20% of the total
known/visible width, have been received to date with an average of 1.98% Li2O over 23 metres. The
results of 213.4 metres of samples in 6 channels remains outstanding;
-Spodumene has been identified in all but 6 metres of channel cut to date.;
-The results from Electron Microprobe work on spodumene from selected polished thin sections
indicate similar Fe2O3, Na2O and Al2O3 content as the PAK deposit.
Sudbury, Ontario, November 7, 2018 – Frontier Lithium Inc. (TSX.V: FL) (the “Company) is pleased to
announce the new discovery of the Spark Pegmatite on the PAK Lithium Project (“The Project”), located only
2.3 km north-west of the PAK deposit (Figure 1). The showing is an LCT (Lithium Cesium Tantalum)
pegmatite intruding vertically into metavolcanics and mafic schists. It was discovered in the final days of a
geological mapping program in late September 2018. It is located on a topographic high and very well
exposed (3.5 hectares) due in part to the latest forest fires of 2012.
Initial mapping and sampling indicate significant zones that appear similar to the Lower Intermediate Zone at
the PAK Deposit. Aplite, feldspar and spodumene is common throughout the outcrop exposure.
Unfortunately snow cover in October prevented any detailed mapping and work was largely restricted to
channel sampling. A drone-derived high resolution ortho-corrected image complete with detailed DEM (Digital
Elevation Model) was collected and will form the basis for modelling and future drill programs. Figure 2 is a
view from the west showing the trace of the channels draped over the topography.
No mechanized stripping was required to complete channel sampling. As a result, one 23 metre channel
(Channel 33) was cut at the time of discovery and an additional 6 channels (213.4 m) were cut three weeks
later in October just before freeze-up suspension of The Project. The presence of spodumene was described
and is ubiquitous throughout the channels. Spodumene is abundant in 10 to 85% of each sample interval in
194.1 of the total 236.4 metres cut. There was only 6 metres of channel where spodumene was not identified.
The initial channel averaged 1.98% Li2O over 23 metres with a 2 metre zone of 3.44% Li2O. The assay and
location for the channels are presented in Table I and Table II respectively. The remaining results from the
recently cut channels will be disseminated as they are received and pass quality assurance and control
protocols (QAQC).
Limited EMP (Electron Micro-Probe) work was completed on spodumene from polished thin sections from one
sample collected from Channel 33 and from five additional grab samples across the pegmatite. The results
indicate similar Na2O and Al2O3 content for spodumene as the PAK Deposit (Figure 3). The iron oxide (Fe2O3)
content from this initial work within the spodumene averages 0.15%, which at this point in time is analogous to
the PAK Deposit. More work will be completed on the impurity assessment as the pegmatite zonations
become better understood.

“The Spark Pegmatite discovery is a significant event for Frontier Lithium and all project stakeholders” stated
Trevor Walker, President and CEO. “The showing appears to be analogous to the PAK Deposit. We will be
expedient with our assessment of the showing because we see the leverage it represents for the further de-
risking it provides to the development of the PAK Lithium Project”.
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, channels are cut with a motorized circular diamond saw, and are 4 cm
wide and 10 cm deep. The channels are typically oriented perpendicular to the strike of the pegmatite internal
mineralogical zones and are cut continuously across the zones. The samples are removed using a hammer
and chisel. The length of a channel is determined by the width of the pegmatite zone. Offset channels are cut
where deemed appropriate. Sample lengths typically are 1 metre but can be less depending on zone

mineralogy and boundaries. Samples are described, placed into a poly sample bag with a numbered sample
tag and then shipped to the assay lab for quantitative multi-element analysis.
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 duplicate samples were also taken in accordance with industry recommended practices.
Other Matters
The Company also announces that it has granted an additional 500,000 stock options. The options are set for
a period of five years, expiring on November 7, 2023. The options are prices at $.40 and are subject to
regulatory approval.
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% Li2O 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 Pre-Feasibility Study shows a Proven and Probable
Reserve of 5.77 million tonnes of 2.00% Li2O.
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.
