Nemaska Lithium Inc. ("Nemaska Lithium" or the "Corporation") (TSX:NMX) (OTC:NMKEF) is pleased to announce the signing of a supply agreement (the "Agreement") of spodumene concentrate with Hanwa Co., Ltd. ("Hanwa") acting as agent for General Lithium Corp. ("GLC"), the latter having signed the Agreement as intervenor.

Under this Agreement and through its wholly-owned subsidiary Nemaska Lithium Whabouchi Mine Inc., Nemaska Lithium will supply a significant quantity of spodumene concentrate on a take-or-pay basis at a market priced-based formula, at the time of delivery. The supply period will commence after the construction of the Whabouchi Mine and continue up to the full ramp-up of the electrochemical plant in Shawinigan.

"We are very pleased to conclude this commercial relationship with Hanwa, a leading, Japan-based, global trading company, and GLC, a China-based company specialized in R&D, production and sales of lithium products and one of the top class spodumene converters in China", declared Guy Bourassa, President & Chief Executive Officer of Nemaska Lithium.

Bourassa continued, "Our business plan remains to be vertically integrated and to sell lithium hydroxide and lithium carbonate from our electrochemical plant in Shawinigan; however, given that the Whabouchi mine will be in production about a year before the electrochemical plant is ready to be commissioned, we decided to be opportunistic and sell spodumene concentrate in the interim, effectively enabling us to generate revenue by the last quarter of 2019."
