NOUVEAU MONDE INCREASES ITS INDICATED RESOURCES TO 95.8 MT AT A GRADE OF

4.28% CG FOR ITS WEST ZONE GRAPHITE DEPOSIT – MATAWINIE PROPERTY

Symbol: NOU (TSX Venture), OTCQX: NMGRF, Frankfurt: NM9

June 27th, 2018 FOR IMMEDIATE RELEASE

SAINT-MICHEL-DES-SAINTS, QUEBEC – Nouveau Monde Graphite Inc. (TSX-V: NOU)

(“NMG” or “Nouveau Monde”) is pleased to announce the results of an updated pit-

constrained Mineral Resource Estimate (the “Current Resource”) concerning its West

Zone Deposit, located on the Tony claim Block, part of its Matawinie graphite Property.

Nouveau Monde’s President and CEO Eric Desaulniers commented: “Our recent work has

nearly tripled our Indicated Mineral Resources while only increasing the maximum width

of the pit envelope by 30 m.” Desaulniers adds: “Industry leading market analysis has

indicated that a global supply deficit of natural graphite is expected by 2022-23 principally

caused by the phenomenal growth in the lithium-ion battery market. With this Current

Resource, we are now working towards an optimized mining plan with a projected flake

concentrate production output of around 100,000 tonnes per year. While the parameters

used to generate the pit envelope were different than those used for the prefeasibility

resource estimate, they should favorably influence the project’s economics.”

The Current Resource is summarized in Table 1 below and is compared to the previous

pit-constrained Mineral Resource Estimate (the “Previous Resource”) first published on

a March 2, 2017, press release. The Current Resource is based on a newly acquired land

package (see July 5, 2017 press release), the properties’ Prefeasibility Study (refer to the

October 25, 2017 press release), on the diamond drilling program completed in January

2018 (refer to the March 1, 2018, press release), new geotechnical data and

hydrogeological modelling as well as future market outlook. The results presented here

will serve as the basis for a Feasibility Study, scheduled to be completed in Fall of 2018.

1 The mineral resources provided in this table were estimated using current Canadian Institute of Mining, Metallurgy

and Petroleum (CIM) Standards on Mineral Resources and Reserves, Definitions and Guidelines.

2 Mineral resources that are not mineral reserves have not demonstrated economic viability. Additional trenching and/or

drilling will be required to convert Inferred and Indicated Mineral Resources to Indicated and Measured Mineral

Resources.

3 All analyses used for the Resource Estimates were performed by ALS Minerals Laboratories and delivered as graphitic

carbon (“% Cg”), internal analytical code C-IR18.

4 Inferred Mineral Resources represent material that is considered too speculative to be included in economic

evaluations. Additional trenching and/or drilling will be required to convert Inferred Mineral Resources to Indicated or

Measured Mineral Resources.

5 Current Resource effective June 27, 2018.

6 Previous Resource published March 2, 2017.

7 The Current and Previous Mineral Resources are stated at a cut-off grade of 1.78% Cg and 2.28% Cg respectively.

8 Standards used for this resource update are the same standards produced over the course of the Prefeasibility Study

(results published October 25, 2017). The difference comes from a newly acquired land package (see July 5, 2017 press

release), the south-west extension drilled in 2018, the new hydrogeological and geotechnical information as well as the

updated market outlook.

Various characteristics of the Current Resource pit envelope are compared to the

Previous Resource pit envelope in Table 2.

Resource. Parameters used are summarized in Table 3 of this press release.

Data Sources and Current Resource Estimation Methods

The block model, used to generate the Current Resource of the West Zone deposit, is

based on a total of 105 core drill holes which produced 4,518 samples, as well as 207

samples collected from channeling work in three (3) trenches. In all, 19 mineralized

horizons encased in paragneiss units were interpreted and modelled from this data.

Mineralized material sorting was performed through an automated sorting algorithm

using research ellipsoids centred upon composites.

The indicated resource boundary study is based on the distance between drill holes. The

total thickness of the mineralized volumes is comprised in the same category. The

Indicated Resource is a continuous zone measuring approximately 2.6 km long by 175 m

wide. Drill holes are typically spaced 100 m apart or less from section to section and

spaced every 75 m or less over the sections. All resources outside this perimeter obtain

the inferred category by default.

The Current Resource block model for the West Zone was prepared by Yann Camus, P.

Eng., of SGS Canada Inc. —Geostat (“SGS Geostat”) from Blainville, Québec, using the

Genesis© mining software. Interpolation was performed using inverse square distance

(ID2) as well as different search ellipses which were adapted for the geology of the

deposit. The block model was then fed to GEOVIA’s WhittleTM software to provide an

optimized pit envelope constraining the resources. The parameters used to generate the

pit envelope were different than those used for the prefeasibility resource estimate. The

parameters used are available below in Table 3. Unlike the Previous Resource, the pit

envelope containing the Current Resource was not limited to an elevation of 390 m above

sea level following the conclusions of recent studies including updated market outlook as

well as new hydrogeological and geotechnical information.

It is important to note that Nouveau Monde will be issuing an updated prefeasibility

technical report, completed in accordance with National Instrument (NI) 43-101, detailing

this important change within 45 days following this release. This upcoming report will lay

the groundwork for a feasibility study targeting a production of 100,000 tonnes of

graphite concentrate per year from the West Zone deposit.

The technical data included in this release was prepared by a qualified independent

expert, as defined by the 43–101 Regulation, Yann Camus, Eng., of SGS Canada Inc. —

Geostat.

About Nouveau Monde Graphite

In 2015, Nouveau Monde Graphite discovered a major and high-quality graphite deposit

on its Matawinie property, located in Saint-Michel-des-Saints, 150 km north of Montreal,

Quebec. The discovery led to the announcement of a prefeasibility study on October 25,

2017. The prefeasibility study results revealed projected graphite concentrate production

levels of 52,000 tonnes per year over a 27-year period. In the summer of 2018, NMG will

be launching its first tonnes of concentrated graphite flake manufactured in

demonstration plant. NMG’s demonstration plant has been built for a production capacity

of 2,000 tonnes of concentrated flake graphite for a two-year period.

Moreover, in a vertical integration and sustainable development perspective, the

company is planning the establishment of a large-scale graphite secondary

transformation facility, catering the needs of the booming lithium-ion battery market.

With over 60 years of experience in the world of graphite, NMG’s team develops its

projects with the utmost respect of neighboring communities, while favoring a minimal

ecological footprint. NMG’s project is privileged by direct access to the workforce and

infrastructure needed to operate its mining project, and it can also rely on an abundant,

affordable and renewable source of hydroelectricity.
