Frontier Lithium signals advancement towards feasibility by commencement of a Phase III Metallurgical Study

Sudbury, Ontario, August 22, 2018 – Frontier Lithium (TSX.V: FL) (the “Company”) announced that a final Phase III Metallurgical Study on its PAK Lithium Project is currently underway. This study supports the Company’s commitment to advancing feasibility plans and prospective customer discussions for the development of the PAK Lithium Project.

The comprehensive testwork being performed is two fold: Firstly, to analyze the robustness of the premium technical grade spodumene concentrate flowsheet with varying run-of-mine samples for the demonstration of head grade versus recovery relationships. Secondly, for the production of sample concentrate and it’s ensuing process water and waste material from a larger representative life-of-mine sample.

“In March 2018, the results of the NI 43-101 Pre-Feasibility Study (“PFS”) for the Pakeagama Lake pegmatite exceeded expectations, confirming the rare ability from this deposit to produce premium lithium concentrates suitable for both technical and chemical grade applications. Results from recent flowsheet optimization work and this concluding stage of metallurgical testing and concentrate generation are required to advance dependent technical studies required for bankable feasibility of the potential mining operation and for the advancement of discussions regarding potential future offtake,” commented Trevor R. Walker, President and CEO, Frontier Lithium Inc.

The Company has successfully completed the Phase VI Drill Program which consisted of 1,225m in 9 drill holes targeting the resource’s high grade zone at surface and systematically stepping down to finish below the PFS open pit design at depth. The Company anticipates the pending results of analysis for the drill hole samples over the coming weeks and will promptly release when passing our QA/QC and interpreted for our shareholders.

About Frontier Lithium Inc.

Frontier’s goal is to become a low-cost, fully integrated lithium 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. The deposit boasts its lithium in a rare, high-purity, low-iron spodumene. The initial target market is the glass-ceramic industry which consumes roughly one-quarter 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 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 is working towards developing a viable operation. The Company is currently completing a pre-feasibility study to assess 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 a combination of 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 an Inferred Lithium Resource of 1.9 million tonnes of 2.01% Li2O which has a technical/ceramic grade spodumene with low inherent iron (below 0.1% Fe2O3). 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.
