Key Milestone Reached as NextSource Materials Begins Procurement of

Processing Plant Equipment for its Molo Graphite Mine in Madagascar

NEWS RELEASE – TORONTO, May 11, 2021

NextSource Materials Inc. (TSX:NEXT) (OTCQB:NSRCF) (“NextSource” or the “Company”) is

pleased to announce it has commenced procurement for its Molo graphite mine in Madagascar ,

ahead of expected mine construction in August 2021 and mine commissioning in April 2022.

Since securing a funding package from its new strategic investor, Vision Blue Resources Limited,

the Company has been working diligently with its EPC (engineering, procurement and construction)

firm to complete all engineering design preparation work and final project cost ing estimates.

Purchase orders have now been placed for the following essential processing plant equipment:

• Primary, flash flotation and attrition mills

• Flotation columns and cleaning circuits

• Screeners, crusher and feeders

The fabrication and construction of the Molo graphite mine is on schedule, with commissioning

targeted for April 2022. The processing plant is designed to process 240,000 tpa of ore , and

produce approximately 17,000 tpa of high-quality SuperFlake® graphite concentrate.

Mine-site construction activities are scheduled to begin in August 2021. The plant equipment is

expected to begin arriving in Madagascar in Q4 2021 followed by site installation in Q1 2022. Mine

commissioning is expected to begin in April 2022 , followed by a ramp up to a Phase 1 processing

plant capacity of 240,000 tpa of ore producing approximately 17,000 tpa of high -quality

SuperFlake® graphite concentrate.

President and CEO, Craig Scherba P. Geo., commented,

“We have reached yet another key milestone with the procurement of key items that will form the

backbone of the Molo processing plant. This is a testament to the hard work and diligence of our

technical team.”

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 exceed s 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.

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. It has excellent thermal expansion, can be easily upgraded to 99.97% purity (battery

grade), contains no deleterious substances and has high crystallinity.

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.

Graphite Project located near the village of Fotadrevo in the Province of Toliara, Madagascar

Prepared by Erudite Strategies (Pty) Ltd” dated May 31, 2019 for certain other details and

assumptions relating to the parameters of the project, mineral resource and reserve estimates and

data verification procedures.

ABOUT NEXTSOURCE MATERIALS INC.

NextSource Materials Inc. is a battery materials development company based in Toronto, Canada

that is intent on becoming a fully integrated, global supplier of critical battery and technology

materials needed to power the sustainable energy revolution.

The Company will enter into production in phases and utilize an all -modular build approach to

construct the Molo graphite mine. Mine commissioning is expected to begin in April 2022 followed

by a ramp up to a Phase 1 processing plant capacity of 240,000 tpa of ore, producing approximately

17,000 tpa of high-quality SuperFlake® graphite concentrate.

The Company’s Molo graphite project in Madagascar is regarded as one of the largest and highest-

quality graphite deposits globally and the only project with SuperFlake® graphite. With expected

low-cost operations, and both its mining and environmental licenses in place, NextSource Materials

has forged strategic and exclusive partnerships w ith key supply chain participants to provide

graphite-based anode material to international OEMs for lithium -ion and fuel cell applications, and

graphite for high-end, value-added applications where graphite is an essential material.
