Sudbury, Ontario, Canada on April 23rd, 2019 – Frontier Lithium Inc. (TSX.V: FL) (the “Company” or “Frontier”) is pleased to announce that it has entered into a strategic partnership agreement with XPS Expert Process Solutions (“XPS”) a Glencore company, and Dr. Ahmad Ghahreman, a Queen’s University Professor, to develop a process to refine spodumene concentrate into lithium hydroxide. The partnership reflects Frontier’s commitment to lay the foundation for a regional, vertically integrated Battery Ecosystem energizing Ontario’s drive to prosperity.

The joint project will be conducted in Canada and has commenced with a Phase I bench-scale study that includes single stage dense media separation (DMS), flotation, pyrometallurgy and hydrometallurgy. Phase I is evaluating the potential purity and recovery of lithium from concentrates to ultimately improve commercial understanding and provide data for generation of a continuous pilot process. The test work is expected to take 6-8 months.

“Dr. Ghahreman and XPS are very pleased to be working together with our partner, Frontier Lithium, on this truly collaborative project. The initiative is well aligned with XPS’s mandate to deliver practical, technical solutions and to assist our client partners to achieve their strategic objectives while growing our business,” said XPS’s Vice President, Dominic Fragomeni. “Preliminary results show promise for being able to produce lithium hydroxide at a higher purity and at a lower cost than industry average.

"Leveraging expertise through partnerships echoes Frontier’s approach to foster research and sustainable innovation,” said Trevor Walker, President and CEO of Frontier Lithium. “This alliance will spearhead the production of high-quality battery grade lithium products in Northern Ontario and help establish our region as a significant Canadian contributor to clean energy technology.”
