Key Milestone Reached as NextSource Materials Begins Procurement of Processing Plant Equipment for its Molo Graphite Mine in Madagascar

TORONTO, ON / ACCESSWIRE / 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 costing 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 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.

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.
