Corporate Presentation

Forward-

looking

statement

• During the course of this presentation, Nemaska Lithium Inc. will make a

number of statements with regard to its projects, business strategy and

plan, which could be construed as forward-looking.

• Undue reliance should not be placed on such forward-looking statements,

including but not limited to those relating to (i) any financing plan to raise

additional funds, (ii) the ability of Nemaska Lithium Inc. to complete the

construction of the Whabouchi mine and the Shawinigan plant, and (iii) the

expected unfolding of construction and commissioning as well as the

anticipated start of production at the Whabouchi mine and Shawinigan

plant sites, as they are subject to risks and uncertainties that could cause

results to be materially different than expectations. It is uncertain if

Nemaska Lithium Inc. will be able to complete any financing plan or if

further work will in fact lead to production of mineral resources and of

lithium compounds.

• All of the forward-looking statements made in this presentation are

qualified by these cautionary statements and those made in our other

filings with the securities regulators of Canada including, but not limited to,

the cautionary statements made in the “Risk Factors” section of the

Corporation’s Annual Information Form dated October 10, 2018, and the

“Risk Exposure and Management” section of the Corporation’s quarterly

Management Discussion & Analysis.

• Nemaska Lithium filed a NI-43-101 compliant feasibility study report on

SEDAR on February 23, 2018, concerning its Whabouchi project. All

technical information should be reviewed according to this 2018 feasibility

study.

Project under

construction• Nemaska is building its Whabouchi mine and Shawinigan electrochemical plant in Quebec,

Canada.

Vertically integrated

lithium project

• Nemaska Lithium’s Whabouchi project in Québec is a vertically integrated lithium project from the

raw material at Whabouchi mine to the Electrochemical Plant in Shawinigan where it is transformed

into high-purity lithium hydroxide.

Lowest cost producer

of lithium hydroxide

• With a vertically integrated operation, proprietary process, and access to affordable hydroelectric

power in Québec, the Whabouchi project is being forecast to become a low cost producer of lithium

hydroxide globally.

Near-term cash flow• Whabouchi Mine and concentrator are expected to start production with sales of spodumene

concentrate in 2020. An offtake agreement for the whole concentrate production has been signed

for approximately 2 years while the electrochemical plant is ramping up.

World-class

counterparties

• Nemaska Lithium has secured offtake agreements with LG Chemicals, Johnson Matthey and

Northvolt. The various groups have given the project key endorsements through offtake contracts,

product qualification and financial support.

Strong support from

key stakeholders

• Nemaska Lithium has strong support from the Government of Québec, which holds about 12.5% ofthe Corporation. Additionally, Softbank holds 9.9% of Nemaska and the Cree Nation of Nemaska isa shareholder.

Producing Phase 1

Plant since Feb. 2017

• Nemaska Lithium is producing lithium hydroxide from Whabouchi spodumene concentratedemonstrating its ability to produce high purity lithium hydroxide but also enabling the qualificationof product with off-takers and potential customers. Qualification process started with more than 20potential customers.

Project Financing of CAD 1.1B Completed

• A 94M private placement from world-leader SoftBank Group Corp. SoftBank also

has a right of first offer to purchase up to 20% of lithium salts produced from

Shawinigan.

• A 80M private placement with Ressources Québec

• A 280M public offering through a bought deal

Signed a streaming facility agreement with Orion Mine Finance II LP under which

Nemaska Lithium and Orion will share 14.5% of future production of all lithium products. Net

effect is Orion receives 8.7% of total revenue. The agreement is capped at 5,000 t of product

per year.

“ We have completed our analysis on

the first product sample received from

your phase 1 plant. The quality is

excellent! I am sure that this product

would be readily accepted by all

cathode producers in the market now

and in the future and I am 100%

confident that if you bring a product

like this to market you will have the

best quality product available and

even over time, I doubt this quality

will be surpassed by others.”
