MONTRÉAL--(BUSINESS WIRE)--January 10, 2023--Nouveau Monde Graphite Inc. (“NMG“

or the “Company”) (NYSE: NMG, TSX.V: NOU) in collaboration with Mason Graphite Inc.

(“Mason Graphite”) (TSX.V: LLG, OTCQX: MGPHF) releases the results of a preliminary

economic assessment (“PEA”), according to National Instrument 43-101 Standards of Disclosure

for Mineral Projects (“NI 43-101”), for a new project covering Mason Graphite’s Lac Guéret

graphite deposit, the Uatnan mining project (the “Uatnan Mining Project”) located in Québec,

Canada.

The PEA, conducted by engineering firms BBA Inc. (“BBA”) and GoldMinds Geoservices Inc.

(“GMG”), shows strong economics for NMG’s updated operational parameters and production

volumes targeting the production of approximately 500,000 tonnes of graphite concentrate per

annum over a 24-year life of mine (“LOM”). The proposed Uatnan Mining Project is currently

one of the largest projected natural graphite productions in the world as battery and electric

vehicle (“EV”) manufacturers seek local alternatives for sourcing their graphite-based solutions

amidst growing demand and a projected structural deficit of production as of this year as

supported by Benchmark Mineral Intelligence (December 2022).

Arne H Frandsen, Chair of NMG, declared: “NMG’s vision is to become North America’s most

important producer of battery grade graphite. The Uatnan Mining Project aligns with our vision

of progressive, integrated growth that caters to the market’s requirements for high-quality

graphite materials, local supplies, ESG-driven development, and large volumes to meet EV

production levels. Building on our Matawinie graphite operation’s successes, I am confident that

our extended technical team’s expertise will enable us to develop what is projected to become

one of the world’s largest graphite mines.”

Eric Desaulniers, Founder, President and CEO of NMG, added: “While the core of NMG’s

technical team is extremely focused on developing and advancing our Phase-2 Matawinie Mine

and Bécancour Battery Material projects, it has become increasingly important for our

customers and strategic for our shareholders to accelerate the deployment of our Phase 3. It is

our intention to capture as much market share as possible during this historical period of growth

of lithium-ion battery manufacturing in North America and Europe. I am eager to work with the

Innu First Nation of Pessamit and stakeholders from the Manicouagan region to revive the

mining development of this world-class deposit. The PEA confirms the tremendous potential of

the Uatnan Mining Project as a lever of decarbonization for cleantech markets and

socioeconomic growth for local communities. We will leverage our existing Phase-1 facilities,

the environmental stewardship measures being developed for our Phase-2 operations, our

proprietary technologies, and our demonstrated ESG credentials to advance the Uatnan Mining

Project toward development.”

PEA Results: Uncovering the Potential of the Uatnan Mining Project

NMG and its consultants revisited all components of Mason Graphite’s original mining project

to align the development of the Lac Guéret graphite deposit with today’s market opportunity and

potential customers’ requirements. The most recent technical report from Mason Graphite

(SEDAR, Feasibility study update of the Lac Guéret Graphite Project issued on December 11,

2018) planned for a production of 51,900 tonnes of graphite concentrate per annum, with the

concentrator and tailings storage facility located offsite in the town of Baie-Comeau,

approximately 285 km to the south by road from the mining operations.

The PEA optimizes the Mineral Resources and aims to expand the original mining project

tenfold by targeting the production of approximately 500,000 tonnes of graphite concentrate per

annum, entirely destined for the anode material manufacturing market. The concentrator has

been relocated to be near the deposit with electrical needs that could be sourced from the Manic-

5 hydroelectric power station, located 70 km away.

In line with NMG’s responsible mining approach, plans include progressive site closure with

backfilling of the pit with waste rock as much as possible. Additional characterization of waste

rock and tailings will be included in the next engineering phase to select proper tailings and

waste rock management technologies. Existing baseline studies will be updated based on the

study area to identify any environmental issues, evaluate potential impacts and develop

alternatives for the Uatnan Mining Project.

Commercial parameters were set using current projections of pricing prepared by a third-party

expert for flake concentrate. Design of the Uatnan Mining Project has been tailored to the needs

of the battery and EV market, orienting production volumes for beneficiation in order to produce

active anode material. Natural flake graphite is expected to enter a structural deficit as of 2023

due to the continued growth of lithium-ion battery manufacturing, outpacing supply capacity

from graphite producers (Benchmark Mineral Intelligence, December 2022). Hence, market

perspectives and NMG’s active commercial discussions indicate favorable conditions for

commercializing the Uatnan Mining Project production.

The following lists the economic highlights and operational parameters developed in the PEA.

Graphite is expressed in graphitic carbon (“Cg”):

Table 1: Operational Parameters of the Uatnan Mining Project

OPERATIONAL PARAMETERS

LOM 24 years

Nominal annual processing rate 3.4 M tonnes

Stripping ratio (LOM) 1.3:1

Average grade (LOM) 17.5% Cg

Average graphite recovery 85%

Average annual graphite concentrate production (LOM) 500,000 tonnes

Finished product purity 94% Cg

Cautionary Note: The PEA is preliminary in nature and includes Inferred Mineral Resources,

considered too speculative geologically to have the economic considerations applied to them that

would enable them to be categorized as Mineral Reserves, and there is no certainty that the PEA

will be realized. Mineral resources that are not mineral reserves have not demonstrated economic

viability. Additional trenching and/or drilling will be required to convert inferred mineral

resources to indicated or measured mineral resources. There is no certainty that the resources

development, production, and economic forecasts on which this PEA is based will be realized.

All costs are in Canadian dollars with the exception of the graphite sale price which is provided

in US dollars.

Capital expenditure (“CAPEX”) and operational expenditure (“OPEX”) were established from

test work results, supplier quotations and consultant in-house databases. Estimates currently

being at the market's peak as influenced by inflationary trends, NMG, Mason Graphite and their

consulting firms have refined design, engineering, and construction parameters to enable cost

optimization and competitive pricing. Québec’s affordable clean hydropower underpins the

Uatnan Mining Project’s economic structure and supports NMG’s undeterred carbon-neutrality

commitment.

Considering the significant modifications to Mason Graphite’s original project, NMG initiated a

name change with the collaboration of the Innu First Nation of Pessamit. The deposit is located

on the Nitassinan, the Innu of Pessamit’s ancestral territory, in a sector referred to as Ka

uatshinakanishkat meaning “where there is Tamarack”. Hence, the name Uatnan meaning

Tamarack, a conifer prominent in the area, was chosen to identify the property and project. The

graphite deposit identified on the property is still referred to as the Lac Guéret deposit.

Initial modelling indicates that the Uatnan Mining Project would create approximately 300 direct

jobs.

The Property

The Uatnan property presently consists of 74 map-designated claims totalling 3,999.52 hectares

(“ha”), wholly owned (100%) by Mason Graphite. The Uatnan Mining Project lies within

Nitassinan, the Innu of Pessamit’s ancestral territory and the Rivière-aux-Outardes municipality

located in the Côte-Nord administrative region, Québec, Canada, approximately 220 km as the

crow flies, north northwest of the closest community, the town of Baie-Comeau. The Uatnan

Mining Project is accessible by road 389 and then by following Class 1 forestry roads.

Exploration work on the Uatnan property targeted graphite mineralization and consists to date of

airborne geophysics, prospecting, ground geophysics, trenching/channel sampling and core

drilling. Bulk surface samples and core samples were also collected for metallurgical and

geomechanical tests. Exploration work uncovered significant crystalline flake graphite

mineralization, ultimately leading to the identification of Mineral Resources and Mineral

Reserves (see Mason Graphite’s press release dated November 9, 2015). Due to significant

changes to the project scope, as mentioned above, it was decided that the Uatnan Mining Project

would revert to a Preliminary Economic Assessment level.

On May 15, 2022, NMG concluded an investment to explore the potential development of the

Lac Guéret graphite property (now the Uatnan Property). This agreement aligns with NMG’s

growth strategy with a view to establishing a large, scalable, and fully vertically integrated

natural graphite production, from ore to battery materials, at the western markets’ doorstep.

Mineral Resources

Current Mineral Resources (Table 3) have been estimated for the Uatnan property based on

25,956 assay intervals collected from 43,343.1 m of core drilling and 4 surface trenches

providing 207 channel samples totalling 721.7 m. Proper quality control measures, including the

insertion of duplicate, blank and standard samples, were used throughout the exploration

programs and returned within acceptable limits. Although parameters to determine reasonable

prospects for eventual economic extraction (RPEE) were updated (Table 4), there are no

significant changes between the current Mineral Resources and the Mineral Resources last

published on November 9, 2015.

Notes :

1. The Mineral Resources provided in this table were estimated by M. Rachidi P.Geo., and

C. Duplessis, Eng., (QPs) of GoldMinds Geoservices Inc., using current Canadian

Institute of Mining, Metallurgy and Petroleum (CIM) Standards on Mineral Resources

and Reserves, Definitions and Guidelines.

2. Mineral Resources which are not Mineral Reserves do not have demonstrated economic

viability. The estimate of Mineral Resources may be materially affected by

environmental, permitting, legal, title, market or other relevant issues. The quantity and

grade of reported Inferred Mineral Resources are uncertain in nature and there has not

been sufficient work to define these Inferred Mineral Resources as indicated or Measured

Mineral Resources. There is no certainty that any part of a Mineral Resource will ever be

converted into Mineral Reserves.

3. The Mineral Resources presented here were estimated with a block size of 3mE x 3mN x

3mZ. The blocks were interpolated from equal-length composites (3 m) calculated from

the mineralized intervals.

4. The Mineral Resource estimate was completed using the inverse distance to the square

methodology utilizing three runs. For run 1, the number of composites was limited to ten

with a maximum of two composites from the same drillhole. For runs two and three the

number of composites was limited to ten with a maximum of one composite from the

same drillhole.

5. The Measured Mineral Resources classified using a minimum of four drillholes.

Indicated resources classified using a minimum of two drillholes. The Inferred Mineral

Resources were classified by a minimum of one drillholes.

6. Tonnage estimates are based on a fixed density of 2.9 t/m3.

7. A pit shell to constrain the Mineral Resources was developed using the parameters

presented in Table 4 . The effective date of the current Mineral Resources is January 10,

2023.

8. Mineral Resources are stated at a cut-off grade of 5.75% C(g).

Mining

The mining method selected for the Uatnan Mining Project is a conventional open pit, truck and

shovel, drill, and blast operation. Topsoil and overburden would be stripped and stockpiled for

future reclamation use. The mineralization and waste rock would be mined with 9-m high

benches, drilled, blasted, and loaded into 60-tonne rigid-frame haul trucks with backhoe

excavators.

To minimize the environmental footprint of the Uatnan Mining Project, waste rock would be

hauled to the tailings storage facility where it would be disposed of with the tailings. As of year 5

of operations, waste rock would be backfilled into the mined-out open pit when possible. The

following table presents the subset of Mineral Resources within the pit design for the PEA.

The mine would be operated by an owner fleet, seven days per week, 24 hours per day and be

comprised of a four-crew system working on a two-week in, two-week out rotation. NMG

intends to deploy a zero-emission operating strategy with a battery-powered fleet of haul trucks

and electric equipment as the technology becomes available. In the meantime, the PEA used a

base case with a diesel-operated fleet.

Processing & Recovery

The process flow sheet was developed using the same metallurgical basis used for Mason

Graphite’s updated Feasibility Study issued on December 11, 2018. The main difference between

the two flowsheets, apart from the increased plant capacity, is the intended end-use of the

material. Given that 100% of the graphite concentrate produced from the Uatnan Mining Project

is destined for the battery market, preserving flake sizes is no longer considered in the processing

route. Given this consideration, the flowsheet was simplified by reducing the number of both

polishing and cleaner flotation stages from four to two. This change minimizes the number of

grinding mills and flotation cells required, reducing both the capital and operating costs for the

Uatnan Mining Project.

The flowsheet consists of a mineral sizer to reduce the size of the run of mine (“ROM”) mineral

before it is fed to a SAG mill for primary grinding. The ground mineral then undergoes rougher

flotation, after which the reground and scavenged concentrate is combined with the rougher

concentrate for further processing. The concentrate then undergoes two additional stages of

regrinding, first in a ball mill ahead of the first cleaning step, then a second regrind in a tower

mill ahead of secondary cleaning. The resulting concentrate undergoes a final deliming stage to

remove low-grade minus 20-micron particles to maximize the final concentrate grade. The

concentrator tailings are filtered and delivered to the tailings storage facility. The concentrate is

filtered and dried before being trucked 285 km to Baie-Comeau for transport to market.

Economic Evaluation

The CAPEX, summarized below, covers the development of the mine, processing facilities, and

infrastructure required for the Uatnan Mining Project. It is based on the application of standard

costing methods of achieving a PEA which provides the accuracy of -30% to +50%. The

operating cost covers mining, processing, concentrate haulage, tailings and water management,

general and administration fees, as well as infrastructure and services.

Next Steps and Quality Assurance

The PEA shows that the Uatnan Mining Project is technically feasible as well as economically

viable. It further strengthens NMG’s active commercial discussions and the Company’s plans for

growth through a Phase-3 expansion.

On the basis of these positive results, NMG intends to launch an updated feasibility study in

compliance with the option and joint venture agreement signed with Mason Graphite. The

Uatnan Mining Project will have to go through the process of the Government of Québec’s

Environment Quality Act with the objective of obtaining a ministerial decree.

NMG is committed to extending its approach of open and proactive engagement with Indigenous

Peoples and local stakeholders to the Uatnan Mining Project. The Company plans to maintain a

transparent dialogue with the Innu First Nation of Pessamit as it advances the project

development to ensure the respect of their rights, the protection of the environment, their culture,

way of life and spirituality, as well as the inclusion of their perspective, and traditional

knowledge. NMG also pledges to expand its relationships with stakeholders from all horizons to

foster mechanisms for collaboration and shape a project generating shared value.

Shareholders and analysts are invited to attend a webcast Investor Briefing this morning,

Tuesday, January 10, 2023, at 10:30 a.m. ET. Hosted by President and CEO Eric Desaulniers

with the participation of NMG’s Management Team, the briefing will entail a technical

presentation followed by a question-and-answer session. Registration should be completed prior

to the start of the briefing at:

There is no certainty that the economic forecasts on which this PEA is based will be realized.

The PEA is preliminary in nature and includes Inferred Mineral Resources that are considered

too speculative geologically to have the economic considerations applied to them that would

enable them to be categorized as Mineral Reserves, and there is no certainty that the PEA will be

realized. Mineral Resources that are not Mineral Reserves have not demonstrated economic

viability. Additional trenching and/or drilling will be required to convert Inferred Mineral

Resources to Indicated or Measured Mineral Resources. There is no certainty that the resources

development, production, and economic forecasts on which this PEA is based will be realized.

There are a number of risks and uncertainties identifiable to any new project and usually cover

the mineralization, mineral processing, financial, environmental and permitting aspects. NMG’s

Phase-3 is no different, and an evaluation of the possible risks was undertaken as part of the

PEA.
