In the following text, graphite is expressed in graphitic carbon percentage (% Cg).
The pit constrained resource located in the West Zone deposit includes 95.8 million tonnes grading 4.28 % Cg of Indicated Resources and 14.0 million tonnes, grading 4.19 % Cg of Inferred Resources, using a cut-off grade of 1.78 % Cg. Refer to the Company’s press release dated June 27, 2018 for further details.
|Only the West Zone of the Tony Claim Block has been considered in the FS|
|Mining is performed by open pit using a fully electric truck and shovel operation|
|The mining production schedule is limited to a 16-hour work day, 5 days a week as to reduce the social impact of the project|
|Mining is to be executed under contract services under the supervision of Nouveau Monde|
|Mine life of 25.5 years, with a total diluted Probable Reserve of 59.8 Mt grading 4.35 % Cg|
The Mineral Reserve estimate was prepared by MC-DRA, using the Mineral Resource Estimate completed by SGS Canada Inc. – Geostat from Blainville, Québec, which was released by Nouveau Monde on June 27, 2018. The Mineral Reserves include the Indicated Mineral Resources that have been identified as being economically extractable and which incorporate mining losses and the addition of waste dilution. In addition, Mineral Reserve estimation considers the design of an operational pit that will form the basis of the production plan. This pit design uses the economic pit shell as a guideline and considers geotechnical constraints, smoothing of the pit walls, adding ramps to access the pit bottom and ensuring that the pit can be mined using the initially selected equipment. Table 1 summarizes the pit design parameters.
Table 1 : West Zone Open Pit Design Parameters
|West Wall (Hanging wall)||East Wall (Footwall)|
|Bench Height (double benching)||10||10||m|
|Bench Face Angle||75||75||degrees (°)|
|Overall Slope Angle||55||60||degrees (°)|
The FS shows an average ROM feed rate of approximately 9,200 tonnes per day based on the current proposed mine work schedule of 5 days/week, two (2) 8-hr shifts per day (16 hr work day), a 25.5-year mine life and an average LOM waste to ore strip ratio of 1.06:1. The mineable portion of the reserves was developed based on an economic cut-off of 2.20 % Cg.
Once a dilution of 5 % and mining losses are considered, the Mineral Reserves extracted over the course of the mine life totals 59.8 Mt grading 4.35 % Cg in the Probable category as presented in Table 2 below:
Table 2 : Mine Reserves for the West Zone
|Class||Reserves (Mt)||Grade (% Cg)||Graphite Tonnage (Mt)|
|*Graphite tonnage is based on an average graphite recovery of 94 % and concentrate product purity of 97 %.|
Reserves categories are compliant with Canadian Institute of Mining, Metallurgy and Petroleum Definitions Standards for mineral resources in concordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects. The cut-off grade for the open pit Mineral Reserves is 2.20 % Cg.
The mine infrastructure has been designed to facilitate an environmentally friendly project while lowering the visual impact on neighbouring communities. The processing plant and the co-disposal pile of tailings and waste rock will be located less than 500 metres from the mine so as to minimize truck cycle times and lower the project’s operating costs. In addition, the mine plan conceived for the FS considers the progressive backfilling of waste rock and tailings within the pit to further minimize the project’s environmental footprint and allows site rehabilitation during the operating life of the mine. The innovative mine waste rock and tailings management plan, as well as the water management infrastructure was designed by SNC-Lavalin Inc.
The mine will be using an all-electric zero-emission mine fleet, consisting of electric battery-driven 36.3-tonne mining trucks, battery-driven front-end loaders, cable reel excavators and bulldozers, and battery-driven service vehicles. The mine will also be using an electric in-pit mobile crusher and overland conveyor system to feed crushed material to the plant. The technology used in this fleet has been developed by Medatech Engineering Services Ltd. and ABB Inc. which assisted MC-DRA in preparing a fully-electric equipment fleet estimate. This information was then passed to a mining contractor to establish a technical and commercial proposal for the mine operation on a contractual basis as well as on the basis of a fully-electric equipment fleet.
Mr. Desaulniers continued, “We have designed a state-of-the-art mine that not only maximizes efficiency but also aims to be one of the most ecofriendly mines in the world, having a very low carbon footprint relative to our peers. This is a key product differentiator, especially for our electric vehicle manufacturing customers whose environmental and social acceptability values align perfectly with our own.”
PROCESSING AND RECOVERY
|Processing and Recovery Highlights|
|Average annual processing rate: 2.35 million tonnes|
|Average annual graphite concentrate production: 100,000 tonnes|
|Average graphite recovery: over 94 %|
|Finished product purity: over 97 %|
The Matawinie concentrator combines proven technology and innovative ideas to conceive a robust flow sheet with remarkably high graphite recoveries. Since the Prefeasibility Study, additional variability test work and Locked Cycle Testing has been performed at SGS Mineral Services to confirm that a recovery of over 94 % is attainable while maintaining over 97 % product purity.
The flow sheet consists of in-pit crushing, followed by multiple steps of grinding and flotation separation circuits. The graphite concentrate is then filtered, dried and classified to produce four (4) high purity products.
Table 3 : Graphite Concentrate Distribution
|Flake Size||Distribution (%)||Assay (% Ct)||Tonnes of Product|
|+48 mesh||15 %||97.3 %||14,800|
|+80 mesh||33 %||96.7 %||33,400|
|+150 mesh||28 %||97.6 %||27,700|
|-150 mesh||24 %||97.8 %||24,100|
|The totals may not add up due to rounding.|
The plant rejects are processed through flotation and magnetic separation to produce two (2) streams: sulphide and non-sulphide tailings. These streams are thickened and filtered before being sent for co-disposition.
GRAPHITE CONCENTRATE SALES PRICE ASSUMPTION
The graphite concentrate sales price used for the FS was established at $ 2,261 (1,730 USD) per tonne. The selling price was calculated using price forecasts provided by Benchmark Mineral Intelligence (Benchmark). Benchmark is an independent credible source who compiles international graphite prices for various commercial size fractions and concentrate purities. The Tony Block’s West Zone graphite concentrate value was calculated based on the weighted average of each size fraction and purity obtained during the metallurgical testing presented in Table 3. Table 4 presents graphite concentrate prices in USD for various size fractions calculated for years 2022 through 2047.

TOWARDS VALUE-ADDED GRAPHITE PRODUCTS
In a vertical integration and sustainable development perspective, Nouveau Monde is planning the establishment of a large-scale graphite secondary transformation facility in addition to its mining project. The goal is to transform part of its graphite concentrate into spherical graphite used in the booming Lithium-Ion battery market as well as develop expandable graphite products used in various industrial applications.
Since 2013, Nouveau Monde has held more than 50 meetings with people or groups from the town of Saint-Michel-des-Saints and nearby communities. During these presentations and consultations, important ties of trust have been forged between the population and Nouveau Monde. An accompanying committee, composed of citizens and regional experts, is working with Nouveau Monde’s technical team to ensure that the project grows while respecting the host environment and, above all, contributes to the regional dynamism.
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. This discovery eventually led to the completion of this Feasibility Study which reveal strong economics with a projected graphite concentrate production level of 100,000 tonnes per year over a 25.5-year period.
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 favouring a minimal ecological footprint. NMG 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.
