NextSource Materials Inc. Granted Registered Trademark for SuperFlake®

NEWS RELEASE – August 16, 2017

NextSource Materials Inc. (TSX:NEXT) (OTCQB:NSRC) (“NextSource” or “the Company ”),

announces that it has successfully registered SuperFlake® as a trademark in Europe.

The registration of the S uperFlake® trademark means that NextSource now has the exclusive

right to use this trademark on all natural graphite sold in the European Union that it produces from

its feasibility-stage Molo Graphite Project in Madagascar.

In conjunction with its application for trademark registration in Europe, the Company also applied

for and is awaiting status on being awarded the exclusive right to use SuperFlake® in Canada,

the United States, South Korea and Japan . These key jurisdictions represent the top demand

markets for flake graphite and the locations where NextSource intends to sell its natural flake

graphite concentrate.

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

“Numerous potential offtakers and end -product manufacturers have verified through their own

extensive and independent testing that our Molo graphite c oncentrate meets or exceeds the

quality requirements for all the major end-markets for natural flake graphit e, namely refractories,

anode material for lithium -ion batteries, specialty graphite foils for the consumer electronic s and

fire retardant industries and graphene ink applications. The SuperFlake ® trademark reinforces to

the marketplace that our Molo Project will produce a distinct graphite concentrate, that in turn can

provide our potential strategic partners with a means to further differentiate their product offerings

to their respective customers.”

As detail ed in the June 2017 updated Feasibility Study, the 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) and contains no deleterious substances. The

SuperFlake® graphite concentrate also 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.

The timing of this trademark registration in Europe coincides well with the Company’s

accelerated timeline for targeted Phase 1 production of SuperFlake® graphite in 2018.

Phase 1 will consist of a fully operational and sustainable graphite mine with a permanent

processing plant capable of producing approximately 17,000 tonnes per annum (“t pa”) of high -

quality SuperFlake® graphite concentrate per year over a mine life of 30 years.

The results of the Company’s updated Feasibility Study were previ ously announced on June 1,

2017 and highlighted the following:

 Phase 1 will utilize a unique, fully-modular build platform, resulting in a build cost of only

US$18.4 million and a build time of just 9 months

 The Molo Project will have the lowest capital mine cost of any new and competing graphite

project and one of the lowest operating costs in the industry to ship SuperFlake ® graphite

concentrate to European ports on a full-cost, CIF basis

 Using current-day flake graphite prices and realistic production volumes, Phase 1 of the

Molo mine realizes a pre-tax internal rate of return (IRR) of 2 5.2% and a post -tax IRR of

21.6%.

 Eventual Phase 2 expansion to approximately 50,000 tpa of SuperFlake® graphite

concentrate will also incorporate the Company’s unique modular build approach and can be

efficiently implemented as market demand requires.
