Nouveau Monde Starts Graphite Production at Its Demonstration Plant

SAINT-MICHEL-DES-SAINTS, Quebec, Sept. 18, 2018 -- Nouveau Monde Graphite Inc. (TSX-V:NOU) (“Nouveau Monde ”) is

pleased to announce the successful mechanical commissioning of the wet circuit of its 3.5 tons per hour (tph) demonstration

plant located in Saint-Michel-des-Saints, Quebec. An overview of the processing plant is depicted below.

• Demonstration plant facilities (part 2)

• Flotation process

Mechanical commissioning of the flotation circuit up to the filter press was completed during the week of September 3 rd.

Commissioning of the dry side of the demonstration plant including dryer, classification screen, and bagging system is

scheduled for later in September 2018.

Grab samples of the +80 mesh cleaning circuit 3 rd cleaner concentrate were submitted for independent chemical analysis by

SGS Minerals in Lakefield. The results are presented in Table 1 and reveal that the total carbon grades of the +50, +80, and

+140 mesh size fractions are above the minimum concentrate grade target of 95% C(t). Given that these high concentrate

grades were already obtained during mechanical commissioning is very encouraging and confirm the effortlessness that the

medium, large and jumbo flakes of the Matawinie graphite ore can be upgraded to at least 96% C(t).

Table 1: Demonstration Plant Total Carbon Grades:

Size Fraction Total Carbon Grade in %

+50 mesh 98.0

+80 mesh 96.7

+140 mesh 97.9

With mechanical commissioning of the wet circuit completed, the attention will focus on optimizing the metallurgical

performance of the circuit in the coming weeks. During the next two years of operation, several alternative processing

technologies will be evaluated to determine if the results obtained in the laboratory scale metallurgical program that was

completed to support the feasibility study can be further improved.

The demonstration plant represents a significant scale-up from laboratory scale testing, which typically uses 2 kg test

charges. Although two bulk sample were processed in flotation pilot plants rated at 1 tph at SGS Lakefield in 2015 and 2018,

these plants were operated as concentration production campaigns and operating hours were insufficient to optimize the

circuit conditions. The ability to operate the demonstration plant in Saint-Michel-des-Saints for the next two years provides a

unique opportunity to fully optimize all aspects of the process and to provide very specific process design criteria for the

detailed engineering phase.

The demonstration plant also provides a very good training opportunity for plant operators in preparation of commercial

production. Training and operating protocols that are being implemented for the demonstration plant can be easily transferred

to commercial production. The good understanding of the process and response of the Matawinie ore as well as readily trained

operators are expected to accelerate the ramp up phase of the commercial plant.

In order to feed the demonstration plant, 5000 tonnes of ore were blasted a couple weeks ago from the West Zone Deposit.

This material is scheduled to be sent to the plant shortly to ramp up production to full capacity. In the next two years, a total

of 40 000 tonnes are planned to be collected and shipped to the demonstration plant which is located 16 km by road from the

extraction site. A video illustrating the blasting of approximately 5000 tonnes of ore (left) and 4000 tonnes of bedrock (right) for

the tailing’s basin is available through this link:

Other developments

Nouveau Monde is also making great strides in the construction of its tailings facilities as well as its various water

management basins. These necessitated a blasting of about 18 000 tons as well as a blasting of about 5 000 tons of sterile

material, or the equivalent of blasts that we will find during the commercial mining exploitation. The tailings and water

treatment facilities will not only serve to properly manage the plant waste, but it will also provide real-world data which will be

used as a basis for our planned commercial operations. Furthermore, three experimental tailings cells were added to the site

to test new and innovative ideas in order to improve our tailing management. The construction of the tailings facilities is

scheduled to be completed by the end of October.

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 north of Montreal, Quebec. This discovery led to the completion of a Prefeasibility Study which

revealed strong economics with a projected graphite concentrate production level of 52,000 tonnes per year over a 27-year

period (see Press Release dated October 25, 2017). In the coming weeks, Nouveau Monde will be distributing its first tonnes

of graphite concentrate to interested parties. The demonstration plant has been built for a production capacity of 2,000 tonnes

of concentrated flake graphite over 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.
