MONTRÉAL--(BUSINESS WIRE)--March 25, 2025--Nouveau Monde Graphite Inc. (“NMG”

or the “Company”) (NYSE: NMG, TSX: NOU) issues the results of the Updated Technical

Feasibility Study Report for the Matawinie Mine and Bécancour Battery Material Plant

Integrated Graphite Projects (the “Updated Feasibility Study”) carried out in accordance with the

National Instrument 43-101 (“NI 43-101”). Conducted by BBA Inc. and various specialized

consultants, the Updated Feasibility Study pulled from NMG’s 2022 Feasibility Study and

updated key parameters in light of technological development, project optimizations, engineering

advancement, and updated economic factors.

NMG’s integrated production model, covering the full value chain from mining to advanced

processing, is designed to cater to the North American electric vehicle (“EV”) and energy

storage market with a turnkey, local source of natural graphite active anode material. NMG has

signed offtake agreements with Panasonic Energy Co., Ltd. (“Panasonic Energy”), a wholly

owned subsidiary of Panasonic Holdings Corporation (“Panasonic”) (TYO: 6752), and General

Motors Holdings LLC, a wholly owned subsidiary of General Motors Co. (collectively, “GM”)

(NYSE: GM), (together, NMG’s “Anchor Customers”) covering more than 80% of the

Company’s planned Phase-2 production of active anode material.

Results of the Updated Feasibility Study indicate that NMG’s Phase 2 is technically feasible as

well as economically viable. Upon a positive final investment decision (“FID”), the Matawinie

Mine and Bécancour Battery Material Plant could be built and enter commercial production

within less than three years. Considering that its project financing, nearly 100% of its revenue, a

significant amount of its capital expenditures and interest expenses are expected to be

denominated in U.S. dollars, the Company has aligned the Updated Feasibility Study financial

metrics with this currency, enabling a better representation of the underlying economic realities

of the cash flows associated with this integrated project and the associated capital structure.

Arne H Frandsen, Chair of NMG, said: “The underlying driver for NMG’s ore-to-battery-

material business is undeniable. While inflation, geopolitics, and trade dynamics create

turbulences, we are focused on delivering on our mission to responsibly produce carbon-neutral

advanced graphite materials to power the energy transition. Today’s results demonstrate the

attractive operation that we have engineered within a stable jurisdiction and underpinned by

high ESG principles to help North American manufacturers secure and reshore their supply

chain.”

Eric Desaulniers, Founder, President, and CEO of NMG, declared: “We have been hard at work

over the past months to examine, challenge, and refine every component of our future

operations. The input of our Anchor Customers coupled with advanced precision through

engineering, equipment specifications, procurement, and construction planning have enabled us

to optimize our projected Phase-2 commercial production. We are confident that our plans will

deliver a performing and competitive operation, supplying highly specialized products to our

Anchor Customers. I am eager to present the results to our financial partners in view of FID.”

Integrated Production, From Ore to Battery Materials

Leveraging the Matawinie Mine production as feedstock for the Bécancour Battery Material

Plant, NMG has developed an integrated material flowsheet to maximize the production of high-

value active anode material destined to the battery market segments. Hence, the two facilities are

set to operate in tandem to maximize operational efficiencies and margins along the value chain.

The after-tax IRR exceeds the pre-tax IRR, driven by the favorable impact of eligible tax credits, such as the

Canadian Clean Technology Manufacturing Investment Tax Credit, Zero-Emission Technology Manufacturing

(ZETM) tax measures, provincial tax holidays for large investment projects and other available incentives.

Both greenfield projects, the Matawinie Mine and Bécancour Battery Material Plant were costed

using test work results, Phase-1 operations, supplier quotations and consultants’ in-house

databases. NMG and its consulting firms have refined design, engineering, and construction

parameters to enable cost optimization. Furthermore, reserved blocks of Québec’s affordable

clean hydropower underpins the Company’s operations, economics structure and carbon-

neutrality commitment.

NMG’s integrated business model, with a secured feedstock, close-by operations at the western

market’s doorstep and operational flexibility to adapt production based on demand, represents a

stable and cost-effective structure in today’s everchanging macroeconomics.

The Company’s advanced processing capacities at the future Phase-2 Bécancour Battery

Material Plant enable tailored production to unique customer specifications. The majority of the

future Matawinie Mine production is set to be refined into active anode material, while a portion

of jumbo and large high-purity flake graphite is set to be directed to specialty markets, with some

flexibility in the allocation of volumes.

The Updated Feasibility Study incorporates NMG’s supply agreements with Panasonic Energy,

GM and Traxys, as well as market studies by Benchmark Mineral Intelligence, a recognized,

regulated and independent price reporting agency. NMG’s previously announced offtake

agreements, which are subject to completion of conditions precedent and the project-related

agreements, with its Anchor Customers provide visibility, pricing confidence, and reduced

commercialization costs.

Matawinie Mine

The Matawinie Mine remains largely the same as reflected in NMG’s previous technical report.

The Updated Feasibility Study considers revised key parameters and costs, leveraging

advancement in the project since the 2022 report, namely through detailed engineering,

preparatory work at the site, key contracts awarded and/or negotiated, procurement planning,

construction preparation, as well as optimization of operations between the two Phase-2

facilities.

The Matawinie graphite property, in which the Company owns a 100% interest, is located

approximately 120 km as the crow flies north of Montréal, Québec, Canada, in Saint-Michel-des-

Saints. The Tony Claim Block, part of the property, is composed of 159 exclusive exploration

rights totaling 8,266 hectares. Since the deposit discovery, a comprehensive exploration program

identified crystalline flake graphite mineralization, ultimately leading to the definition of Mineral

Resources and Mineral Reserves (as presented below).

The Mineral Resources for the West Zone of the mining property is based on a total of 8,274

assay intervals collected from 27,888 m of core drilling and three surface trenches providing 207

channel samples. Proper quality control measures, including the insertion of duplicate, blank, and

standard samples, were used throughout the exploration programs and returned within acceptable

limits.

The future Matawinie Mine site is easily accessible via the dedicated access road that NMG built

to connect to the local highway and is close to key infrastructure, including paved roads and

high-voltage power lines, and the regional community, which provides a pool of workers and

contractors. The project is in proximity to the Montréal metropolitan area, which also has skilled

labor and many key suppliers.

Since 2015, multiple metallurgical process development and optimization programs have been

carried out on samples from the Matawinie graphite mineralization zones. The programs focused

on the development of a flowsheet that maximizes concentrate grade and recovery, while

minimizing flake degradation. NMG has been operating the Phase-1 Matawinie Demonstration

Plant since 2018 to help de-risking the process and produce graphite concentrate samples for

customer evaluation and processing technological development. All components incorporated in

the Matawinie Mine process are mature technologies.

With a 25-year life of mine (“LOM”), the Matawinie Mine will leverage the West Zone deposit

for a nominal production of 105,882 tonnes per annum (“tpa”) of graphite concentrate. The

deposit will be mined using conventional open-pit mining methods consisting of drilling,

blasting, loading, and hauling. To maximize the NPV, mining phases have been designed and

incorporated into the mining plan to defer waste rock stripping and provide a balanced blended

feed grade for the on-site concentrator over the LOM. Through crushing, milling, flotation,

cleaning, and drying, the ore will be concentrated to attain 97.5% C(t).

Tailings produced at the concentrator will be segregated after the desulphurization circuit into

low-sulphur content of non-acid generating (“NAG”) tailings and a sulphide concentrate of

potentially-acid generating (“PAG”) tailings. Both NAG and PAG will be filtered to reduce

water content and then co-disposed with waste rock into deposition cells on a lined platform. The

co-deposition storage facility will be located at surface and as of Year 7, tailings and waste rocks

will also be placed in the mined-out areas of the open pit. The deposit will be mined from south

to north to ensure adequate space is available for in-pit backfilling.

A ministerial decree authorizing the Matawinie Mine (Decree # 47-2021) was granted by the

Québec Government and all permits and authorizations pertaining to exploration, geotechnical,

hydrogeological, and early preparatory works to date have been obtained.

Early works at the Matawinie Mine have included thus far tree clearing, construction of the

nearly 8-km access road, preparation of the industrial pad, and civil works for environmental

infrastructure. The site is considered concrete-ready for the start of construction upon a positive

FID, with a number of key contracts having been awarded, including process equipment, the

dedicated powerline and the electrical substation.

Bécancour Battery Material Plant

The Phase-2 Bécancour Battery Material Plant is planned as a comprehensive advanced

processing platform set to receive Matawinie graphite concentrate production for refining and

commercial distribution. Plans for this facility have been substantially revised using inputs from

NMG’s Phase-1 operations, technology development, and engineering.

Approximately 150 km northeast of Montréal on the Saint Lawrence River, in the heart of

Québec’s “battery valley”, NMG’s Bécancour site is located adjacent to its Phase-1 purification

plant, within an established industrial park. The site provides robust local infrastructure with a

direct supply of chemicals from nearby producers, affordable hydroelectricity, multimodal

logistics (international deep-sea port, railway, and expressway) and a regional pool of skilled

workforce.

The future Bécancour Battery Material Plant will regroup shaping, purification and coating

capacities to produce battery-grade active anode material.

The shaping process, essentially a mechanical transformation, reduces the flake size

(micronization) and rounds graphite material (spheronization) to increase the density of the

spherical graphite for battery use. At its Phase-1 facility, NMG has already assimilated and

refined this process, and tested different equipment to inform the engineering of the Phase-2

plant. Shaping generates a micronized graphite by-product to be sold.

Purification removes impurities from the spheronized graphite to bring the product to ≥99.90%

carbon content. Following testing at its Phase-1 Purification Plant plus third-party sites, trade-off

analyses and process optimization, NMG has selected the prevalent chemical purification

technology for its future Phase-2 Bécancour Battery Material Plant. Commercial operations

worldwide have demonstrated the performance and efficiency of this technology in line with

battery manufacturers’ requirements; thus, reducing the technological risks for the project.

Continued optimization of the process to refine environmental performance, operational, and

financial parameters along with sample production are being carried out at partnering facilities to

support detailed engineering and commercialization efforts.

The coating aims at enhancing the electrochemical performance of active anode material in

lithium-ion batteries. To establish the proper technology, precursor type and process parameters,

NMG performed different studies and tests at its Phase-1 facility, in independent laboratories and

at suppliers’ test facilities. Most technologies selected are being widely used in the industry,

further reducing technological risks.

In preparation for the launch of construction, preliminary works – tree clearing, on-site road

construction, site grading – were carried out in 2024.

Responsible Production & ESG

In line with its environmental, social and governance (“ESG”) practices, NMG plans to build and

operate an integrated production that promotes stewardship throughout its value chain. The

Company strives to prevent and limit potential impacts through the introduction of responsible

practices including co-disposal dry stacking of tailings, progressive reclamation of the Matawinie

site, strategy for the electrification of its operations, water recycling, greenhouse gas reduction

measures, and active stakeholder engagement at every stage of project development. NMG has

signed a collaboration and benefit-sharing agreement with the Municipality of Saint-Michel-des-

Saints as well as an impact and benefit agreement with the Atikamekw First Nation of Manawan.

NMG is committed to pursuing its efforts to improve its practices, technologies, products, and

procurement as it advances the detailed engineering, construction, commissioning, and launch of

commercial production. The Company strives to maximize opportunities for Indigenous and

local workers, contractors, and communities throughout the project execution.

Next Steps and Quality Assurance

The confirmation of NMG’s Phase-2 viability through the Updated Feasibility Study enables the

Company to enter its project financing stage with a view to reach FID.

There is no certainty that the economic forecasts on which the Updated Feasibility Study is based

will be realized. There are a number of risks and uncertainties identifiable to any new project and

usually cover the mineralization, process, financial, environment and permitting aspects.

Following an analysis of the major risks to the projects, a P50 management risk reserve of

US$122M is recommended. This reserve is not included in the capital cost estimate but is within

the range of the financial sensitivity analysis of the capital cost. The top risks are: 1) The

optimization of the water treatment process technology; 2) The efficient integration of key Asian

suppliers into the project detailed engineering and construction; and 3) The qualification by the

customers of the product from the Matawinie Mine and the Bécancour Battery Material Plant.

A sensitivity analysis reveals that the viability of the Projects will not be significantly vulnerable

to variations in capital and operating costs within the margins of error associated with the

Updated Feasibility Study estimates. However, the viability of the Projects remains more

vulnerable to the USD/CAD exchange rate and the larger uncertainty in future market prices.
