THE WORLD’S PREMIERLITHIUM OPPORTUNITY

Forward-looking statement

• During the course of this presentation, Nemaska Lithium Inc. will make a number of statements with regard to the Company’s projects, business strategy and plan, which could be construed as forward-looking.

• Such forward-looking statements are subject to risks and uncertainties that could cause results to be materially different than expectations. It is uncertain if further work will in fact lead to production of mineral resources and of lithium compounds.

• Nemaska has filed on SEDAR a NI-43-101 compliant revised and updated feasibility study, published dated June 8, 2016. All technical information should be reviewed according to this feasibility study.

The Keys to Success

Closest near-term lithium hydroxide/lithium carbonate producer

• Phase 1 Plant producing commercial lithium hydroxide samples

• H2-2018: Commissioning of Commercial Mine, Concentrator and Hydromet plant (fully permitted)

Fully integrated from the mine to the end product = credible and safe supplier

• North America’s richest and one of the largest reserves of Spodumene in the world

• 27.3 MT Proven and Probable Reserves for an initial 26 years mine life

Lowest cost and greenest process to produce high purity lithium salts (lithium hydroxide/carbonate)

• Unique electro chemical process• Affordable available hydroelectricity

In-House Experienced Management, Technical, Construction and Plant Start-Up Teams

Supported by the Quebec and Canadian governments through $26M in funding and future project investment

World-class customers – Offtake Agreements in Place

• Johnson Matthey Battery Materials • FMC Corporation Account for ~50% of planned production capacity

Li Project

• Given the current shortage in lithium hydroxide supply, Nemaska Lithium is perfectly timed to enter the chain of supply

• Phase 1 production plant is a sound decision, significantly reduces funds required and de-risk start up of commercial production

• Permitted North America’s richest and one of the World’s largest lithium hard rock mines with at least 26 years reserves

• State of the art processes of producing lithium hydroxide and lithium carbonate - leading advantage over peers

• Signed two commercial offtake agreements for ~50% of end product with credible end users

• Project financing and construction underway

• Supportive Governments
