Nemaska Lithium Inc. (the "Corporation") (TSX: NMX) (OTCQX: NMKEF) (Frankfurt: N0T) is pleased to announce that it has started the qualification of its high purity lithium hydroxide monohydrate products with more than 20 customers globally. The Corporation began shipping samples within 60 days of installing drying and bagging equipment at its Shawinigan Phase 1 demonstration plant. Sample sizes range from 450 g to 350 kg and have been requested by customers ranging from cathode manufacturers, to battery makers to industrial grease users, in addition to our existing offtake customers, which include LG Chemicals, Johnson Matthey and Northvolt.

"We have just achieved a major milestone in our vertically integrated project from mine to plant. This first delivery, completed in less time than expected, confirms our ability to produce superior quality battery grade lithium hydroxide from our Shawinigan Phase 1 plant facility. I want to take this opportunity to commend the efforts of our employees in delivering such a high-quality product", says Guy Bourassa, President and Chief Executive Officer of Nemaska Lithium.

Product specifications of the lithium hydroxide monohydrate shipped and a picture of Nemaska Lithium's team are joined to this press release.

About Nemaska Lithium

Nemaska Lithium Inc. is a developing chemical company whose activities will be vertically integrated, from spodumene mining to the commercialization of high-purity lithium hydroxide and lithium carbonate.
