NextSource Materials Secures Commercial Offtake Agreement with thyssenkrupp Materials Trading

TORONTO, May 25, 2021 - Nextsource Materials Inc. (TSX:NEXT)(OTCQB:NSRCF) ("NextSource" or the "Company") is pleased to announce it has executed an offtake agreement ("the Offtake") with thyssenkrupp Materials Trading GmbH ("thyssenkrupp"), an international trading and services company headquartered in Essen, Germany, for a long-term commercial agreement for the sale of NextSource's SuperFlake® graphite products.

KEY HIGHLIGHTS

• Long-term binding commercial agreement between the parties for the sale of approximately 35,000 tonnes per annum (tpa) of SuperFlake® graphite concentrate from the Company's Molo mine in Madagascar.

• The term of the agreement is 10 years with an automatic 5-year extension.

• Product will be for the refractory and expandable graphite (graphite foil) markets for sale in, but not limited to, Europe, the United Kingdom, North America, Mexico, China and South Korea.

• As Phase 1 initial production of the Molo mine in Madagascar will be approximately 17,000, the requested offtake sales volumes by thyssenkrupp will be phased:

  • Minimum of 7,300 tonnes per annum ("tpa") during Phase 1 initial production, with commissioning targeted in April 2022.

  • Additionally up to 35,000 tpa to be available in Phase 2, with targeted production by Q2 of 2024

  • The initial tonnage volume will be used by thyssenkrupp to verify run-of-mill production of SuperFlake®, which will then trigger the much larger volume expansion of 35,000 tonnes requested.

Wolfgang Schnittker,, CEO of thyssenkrupp Materials Trading commented, "The trustful cooperation with NextSource enables us to further expand our strong presence in the international foundry and refractories industry. It is our unique selling point to competitively serve various industries but especially emerging industries and their highly specified requirements."

NextSource President and CEO, Mr. Craig Scherba said, "This executed offtake agreement for the sale of our SuperFlake® graphite was the culmination of a multi-year process and is yet another significant milestone in the Company's strategy in becoming a graphite producer of consequence. We are extremely pleased to formalize this partnership with thyssenkrupp given their expertise, scale, and extensive global distribution network. We look forward to expanding our relationship together as we organically expand our graphite market share over the years to come."

ABOUT SUPERFLAKE® GRAPHITE

As announced in November 2015, independent testing by various third-party end users of flake graphite confirmed that NextSource's SuperFlake® graphite meets or exceeds quality requirements for all major end-markets for natural flake graphite. The major end-markets are refractories, anode material for lithium-ion batteries, specialty graphite foils used as essential components in the chemical, aeronautical and fire-retardant industries, and graphene in high-end ink and substrate applications.

As detailed in the Molo 2019 Feasibility Study, SuperFlake® graphite concentrate can achieve 98% carbon (C) purity with simple flotation, has excellent thermal expansion, can be easily upgraded to 99.97% purity (battery grade), contains no deleterious substances and has high crystallinity.

SuperFlake® graphite concentrate has excellent flake size distribution that is well above the global average, with 46.4 percent being classified as +80 (large), +65 (extra large) and +48 (jumbo) mesh in flake size. Specifically, 23.6 percent of SuperFlake® graphite concentrate is +48 mesh and greater in size.

SuperFlake® is a registered trademark in the United States, Canada, Japan, South Korea, U.K. and the European Union. These key jurisdictions represent the top demand markets for flake graphite and the locations where NextSource intends to sell its SuperFlake® graphite and anode material.
