Nemaska Lithium achieves a key strategic milestone by securing a chemical conversion facility site at the Industrial Park and Port of Bécancour

MONTREAL, June 01, 2021 - Nemaska Lithium Inc. ("Nemaska Lithium" or "Company") announces that it has entered into an option agreement to purchase a 500,000m? plot of land in the Industrial park and port of B?cancour ("B?cancour") to construct and operate its chemical conversion facility ("Conversion Facility"). The Conversion Facility will form part of an integrated project to market solution with Nemaska Lithium's Whabouchi mine to produce battery grade lithium hydroxide.

The selection of the B?cancour site comes at the end of a rigorous analysis by Nemaska Lithium to identify the best location for the Conversion Facility. The conclusion from the analysis found that the construction and operation of the Conversion Plant in B?cancour offers the following advantages:

• provides direct access to a year-round deep-water port;
• allows plant design, construction and operation to be carried out without the constraints associated with pre-existing buildings;
• simplifies plant construction and provides options for future development; and
• avoids issues associated with the construction and operation of a chemical plant within an urban community.

Gervais Jacques, Chairman of the Board of Nemaska Lithium: "The selection of B?cancour for the construction and operation of its Conversion Facility is an important milestone for the new development path of Nemaska Lithium. This decision will also allow Nemaska Lithium to contribute to the development of the battery materials industry in Quebec in a world-class industrial park. Working together with our key stakeholders, we are building the sustainable economy of the future."

About Nemaska Lithium

Operating in the chemical industry, Nemaska Lithium is a developing company whose activities will be vertically integrated, from spodumene mining to the commercialisation of battery grade lithium hydroxide.
