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.
