In the following text, graphite is expressed in graphitic carbon percentage (% Cg).

The pit constrained resource located in the West Zone represents only a portion of the total mineral resources identified to date on the Tony Block. The latter include 32.9 million tonnes grading 4.50 % graphitic carbon (Cg) of indicated resources and 0.2 million tonnes, grading 4.84 % Cg of inferred resources, using a cut-off grade of 2.28 % Cg. Refer to the Company's press release dated March 2nd, 2017 for further details.


Mining Highlights
Only the West Zone of the Tony Claim Block has been considered in the PFS
Mining is performed by open pit using a conventional truck and shovel operation
The mining production schedule is limited to one shift of 12 hours, 5 days a week so 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 27 years, with a total diluted probable reserve of 33.0 Mt grading 4.39 % Cg


The Mineral Reserve estimate was prepared by MC-DRA, using the Mineral Resource estimate prepared by SGS and released by Nouveau Monde on March 2nd, 2017. The Mineral Reserves are included in 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 includes smoothing 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
Item Value Unit
Bench Height (double benching) 10 m
Berm Width 6 m
Ramp and Haul Road Width 18 m
Bench Face Angle 85 degree
Overall Slope Angle 55 degree

The study shows an average ROM feed rate of 4,850 tonnes per day based on the current proposed mine work schedule of 5 days/week (one 12 hr shift/day), a 27 years mine life and an average LOM waste to ore strip ratio of 1.04:1. The mineable portion of the reserves was developed based on a breakeven cut-off of 2.32 % Cg using the cost and revenue parameters presented in Table 2.

Table 2 : Cost and Revenue Parameters Used for Pit Optimization
(The following parameters could differ from those used for the financial analysis)
Item Value Unit
Mining Cost (Overburden) 4.02 $/t (mined)
Mining Cost (Ore and Waste) 5.18 $/t (mined)
Processing Cost 13.64 $/t (milled)
General & Administrative Cost 3.60 $/t (milled)
Selling Price 1,000 $/t of concentrate
Mill Recovery 94.0 %
Concentrate Grade 97.3 %

Once a dilution of 5 % and mining losses are considered, the mineral reserves extracted over the course of the mine life totals 33.0 Mt grading 4.39 % Cg in the Probable category as presented in Table 3 below:

Table 3 : Mine Reserves for the West Zone
Class Reserves (Mt) Grade (% Cg)
Probable 33.0* 4.39

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 ≥ 2.32 % Cg. * Rounded to the nearest hundred thousand.

The mine infrastructure has been designed to facilitate an environmentally friendly project while lowering the visual impact on neighbouring communities. The processing plant and waste piles will be located less than 1,000 metres from the mine so as to minimize truck cycle times, lower carbon emissions and lower project operating costs. In addition, the mine plan conceived for the PFS considers the progressive backfilling of waste material within the pit to further minimize the project's environmental footprint and promote site rehabilitation during the operating life of the mine.


Processing and Recovery Highlights
Average annual processing rate: 1,222,000 tonnes
Average annual production: 52,000 tonnes
Average graphite recovery: Above 94 %
Finished product purity: Above 97 %

The Matawinie concentrator combines proven technology and innovative ideas to conceive a robust flow sheet with remarkably high graphite recoveries. Locked cycle tests performed at SGS Mineral Services have demonstrated the potential to achieve 97 % recovery. Refer to the Company's press release dated April 11th, 2017 for further details on the locked cycle test results.

The flow sheet consists of 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.

Flake Size Distribution (%) Assay (% Ct) Tonnes of Product
+48 mesh 16.5 % 97.1 % 8,602
+80 mesh 31.5 % 96.9 % 16,424
+100 mesh 11.6 % 96.9 % 6,049
-100 mesh 40.2 % 97.7 % 20,925
Total 100.0 % 52,000

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 for dry-stacking in their respective areas.

Future studies and development work include the construction and commissioning of a demonstration plant. Karl Trudeau, Nouveau Monde's Chief Operating Officer stated: "Processing the West Zone ore at our planned demonstration plant aims to optimize equipment selection and guarantee product quality ahead of our commercial operation". Refer to the Company's press release dated April 19th, 2017 for details regarding the demonstration plant.


The graphite concentrate sales price used for the PFS was established at US$ 1,429 /tonne. The selling price was determined using pricing information, averaged during a period of 60 months (from January 2012 to December 2016) and calculated from the Benchmark Mineral Intelligence (Benchmark) Flake Graphite Price Index ( 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 4. Table 5 presents graphite concentrate values in US$ for various size fractions using a 60-month average value obtained through Benchmark Minerals Intelligence.

Size Fraction Weight Purity (Cg) 60-month
Average Price
+50 mesh 17 % 94-97 % $ 2,197
+80 mesh 31 % 94-97 % $ 1,466
+100 mesh 12 % 94-97 % $ 1,301
-100 mesh 40 % 94-97 % $ 1,124
Weighted Average 100 % $ 1,429

Location, Infrastructure and Feasibility Study

The Tony Claim Block is located in the Saint-Michel-des-Saints area, some 120 km North of Montreal, Québec, Canada. The claim block, including the West Zone, is easily accessible using existing logging roads and is close to quality infrastructure such as paved roads and high voltage power lines, both necessary for industrial activities. An abundance of skilled workforce is available in the community of Saint-Michel-des-Saints as well as in surrounding communities, following the recent closing of multiple logging activities.

Nouveau Monde has already begun working toward its Feasibility Study. Furthermore, data gathering needed to complete the Environmental and Social Impact Assessment is well underway. Following Nouveau Monde's drive to innovate and to develop the Matawinie project to the highest environmental standards, improved tailings management is being designed to further optimize and reduce the footprint of the mining operation. Additionally, the possibility of electrifying parts of the mining operation is being considered in order to minimize its carbon footprint and fully utilize the low-cost hydroelectricity readily available in the area.

Value Added Graphite Study

The recent successful results of the metallurgy tests (see press release of April 11th, 2017) encourage Nouveau Monde to continue to evaluate the possibility of developing value-added graphite products near the mining infrastructure in Saint-Michel-des-Saints.

Community Relations

Since 2012, Nouveau Monde has held more than 200 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 the company. 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.
