Planned Development of the Uatnan Mining Project

NMG published in 2023 a preliminary economic assessment ("PEA"), according to National Instrument 43-101 Standards of Disclosure for Mineral Projects, for the Uatnan Mining Project. The PEA, conducted by engineering firms BBA Inc. and GoldMinds Geoservices Inc., showed 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").

Table 1: Operational Parameters of the Uatnan Mining Project

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.

Table 3: Current Pit-Constrained Mineral Resource Estimate

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

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 town of Baie-Comeau. The Uatnan Mining Project is accessible by road 389 and then by following Class 1 forestry roads.

Sustainability is center to NMG's value proposition and will be reflected in the next phase of work as the Company prioritizes the signature of a pre-development agreement with the Innu First Nation of Pessamit. The Company plans to maintain a transparent dialogue with the First Nation as it advances the project development to ensure the respect of their rights, the protection of the environment, their culture and way of life, as well as the inclusion of their perspective, and traditional knowledge.

As NMG's team expands its relationships with the First Nation, the community and local stakeholders, the Company will prepare for subsequent studies to advance the Uatnan Mining Project. NMG has already mapped out a detailed workplan to enable the preparation of a feasibility study, including on-site fauna and flora inventories, geological surveys, environmental studies, impact assessment, stakeholder consultation, etc. True to its practices in developing the Matawinie Mine, NMG is committed to a responsible, sustainable, and inclusive process to bring the Uatnan Mining Project from opportunity to engineering, construction and commercial production.

NMG will leverage its team of over 100 employees from all specialties - from metallurgy and environment to mining, research and development, and sales - plus its operational Phase-1 concentration and processing facilities to support the development of the Uatnan Mining Project.

Market Underpinnings

NMG's acquisition of the Lac Guéret Property aims at securing the asset in view of the growing demand for locally produced natural graphite and the Company's planned Phase-3 expansion to supply the Western market.

Pushed by growth in electric vehicles, energy storage systems and other clean technology applications, graphite demand for lithium-ion batteries is projected to reach to over 10 million tonnes per annum by 2030, a 537% increase according to Benchmark Mineral Intelligence's (December 2023) latest market assessment.

In late 2023, China and the U.S. have sharpened their respective trade instruments targeting graphite materials. China now enforces restrictions on Chinese graphite materials exports. The U.S. Government has indicated that battery material sourced from China and other foreign entities of concern will not be eligible for EV tax credits under the Inflation Reduction Act. These recent political developments reaffirm the importance of establishing of a local, resilient, and ESG-compliant supply chain of graphite to support battery and EV production.

NMG is projected to become the largest natural graphite producer in North America, fully integrated from ore to anode material, and with demonstrated sustainability performance.
