Top Graphite Processing Engineer to Commission NextSource Materials

Inc.’s Madagascar Graphite Mine

NEWS RELEASE – TORONTO, February 5, 2018

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

pleased to announce that Mr. Oliver Peters M.Sc., MBA, P.Eng., one of the graphite industry’s top

metallurgists and process engineers, will commission the Company’s Molo graphite mine in

Madagascar and act as the Company’s principal process engineering consultant for Phase 1 of

the Molo mine. Mr. Peters will relocate to Madagascar for the commissioning period of the Molo

mine.

Mr. Peters is principal metallurgist and president of Metpro Management Inc. and also currently

serves as the senior metallurgical and process consultant at SGS Minerals (Lakefield) Canada

(“SGS”), where he oversees all graphite process development work for SGS. To date, Mr. Peters

has directed over twelve pilot plant operations at SGS for graphite projects globally. Mr. Peters

was formerly a process engineer at DRA Global (DRA) and has over 20 years of process

engineering experience in Africa and Canada.

Mr. Peters was the head process engineer for NextSource’s 2015 pilot plant operation at SGS,

which is the largest known pilot plant operation completed by any junior graphite company

globally to date. Over 200 tonnes of Molo ore was processed at SGS, creating 13 tonnes of high

quality, SuperFlake® graphite concentrate that was used to develop the process flowsheet for the

Molo mine and enabled NextSource t o provide representative “run-of-mill” bulk samples for

evaluation by graphite offtakers.

Mr. Peters was instrumental in NextSource achieving a very high quality graphite concentrate. As

detailed in the June 2017 Feasibility Study, NextSource’s SuperFlake® graphite concentrate can

achieve 98% carbon (C) purity with standard mineral processing (flotation), has excellent thermal

expansion, can be easily upgraded to 99.97% purity (battery grade) and contains no deleterious

substances. The Company’s 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.

As previously reported, independent testing of the pilot plant material by various potential

offtakers and graphite end-users has confirmed that the Molo SuperFlake® graphite concentrate

meets or exceeds quality requirements for all major end markets for natural flake graphite - anode

material for lithium-ion batteries, refractories and specialty graphite foils. The Molo has also been

verified for graphene ink applications.

FACTORY ACCEPTANCE TESTING AND COMMISSIONING

As NextSource’s principal process engineer, Mr. Peters will first oversee and approve the Factory

Acceptance Testing (“FAT”) stage of Phase 1 of the Molo mine. Phase 1 will have a production

rate of 17,000 tonnes per annum of SuperFlake® graphite concentrate and a mine life exceeding

30 years.

Employing NextSource’s unique, all-modular build approach, Phase 1 will be entirely constructed

offshore to European standards with a build-assembly time of just six months. The processing

plant then will be “turned on” and operationally tested for a one month period (the FAT process).

After a successful FAT, the Molo processing plant will then be dismantled into 35 modules and

shipped to site (one month shipping time) where the modules will be re-assembled within a one-

month period, for a total time of only 9 months from start of construction to production.

The FAT stage is a major project milestone in the mine construction stage where Mr. Peters will

ensure that the mechanical operation of the concentrator equipment meets the quality and

performance specifications created by the process engineering team. The FAT approval process

is a critical step in any mill construction process but in NextSource’s case, it also provides a

significant operational risk advantage versus the competition. Since the modules will be

constructed, connected and fully-tested offshore prior to shipping, the entire construction process

of the Molo processing plant will already be de-risked before it even reaches site. Phase 1

production is targeted for late 2018, subject to project financing.

OVER 80 YEARS OF MINE DEVELOPMENT AND OPERATIONAL EXPERIENCE

With the addition of Mr. Peters, NextSource’s mine operational readiness team now consists of

three former engineers from DRA and with over 80 years of cumulative mine development and

operational experience. The other team members are Mr. Johann de Bruin, the former Managing

Director of DRA, who joined NextSource as a mine engineer consultant in March 2017; and Robin

Borley, NextSource’s senior vice president of mine operations who prior to joining NextSource

was the director of mining for DRA.

DRA is the largest and most successful African-based mining engineering and construction

(EPC/EPCM) company, with 20 offices in 5 continents and over 3000 employees globally.

ABOUT SGS MINERALS CANADA

SGS is recognized as a world leader in the development of concentrator flowsheet design and

pilot plant testing programs. SGS’ Metallurgical Services division was founded over half a century

ago. Its metallurgists, hydro-metallurgists and chemical engineers are experienced in all the

major physical and chemical separation processes utilized in the recovery of metals and minerals

contained in resource properties around the world.
