Frontier Lithium Commences Technical Drilling On The PAK Lithium Project

Sudbury, Ontario –February 23, 2017 – Frontier Lithium Inc. (TSX.V: FL) Frontier (the “Company”),

is pleased to announce the commencement of a technical drilling program on its PAK Lithium Project, in the

Red Lake mining district in Northwestern Ontario, Canada.

The drilling campaign is designed for the collection of data essential for the finalization of geo-technical and

geo-mechanical parameters required for the pending pre-feasibility study (“PFS”). The drilling program will

comprise of approximately 750 metres (“m”) of diamond drilling that will be used to test areas for potential site

infrastructure, as well as determining optimum pit wall angles for a potential mining operation.

It is anticipated that the pending PFS will be completed by the end of May, 2017. “The PFS will outline the

technical and economic parameters of the Project to firstly produce, for the most part technical grade lithium

concentrates for the glass ceramics market”, stated Trevor Walker, President and CEO of Frontier. “Further-

more, management is currently planning future test work on sample concentrates from the deposit to investi-

gate the potential for recovery of downstream lithium compounds suitable for the battery market.” If proven

through positive results, Frontier could not only pursue operations for the production of rare technical grade

lithium concentrates for the ceramic glass market, but could also sell to existing lithium compound producers,

with the added future possibility to produce premium lithium compounds such as hydroxide directly to the bat-

tery market.

Mr. Garth Drever, P.Geo., is the "Qualified Person" for Frontier defined under NI 43-101 and has reviewed

and approved the technical information contained in this news release.

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 $4 million of exploration work has been conducted from

2013 to 2016 on the deposit which boasts its lithium in a rare, high-purity, low-iron spodumene. The Company

has adopted a staged growth approach to exploration and development in order to avoid unnecessary share

dilution – a strategic imperative for the Company. 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, cou-

pled 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 inferior 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 believes the resource

can be developed into a world-class operation. The Company is currently conduction pre-feasibility to pro-

duce lithium concentrates. If production of lithium concentrates can be established from Frontier, the pos-

sible 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 Su-

perior 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 is one of the highest grade lithium mineral resources in North America which 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. Frontier is also evaluating the phased co-

production of tantalum and mica-product concentrates once lithium mineral production has been commercial-

ized.

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 south-

east.
