PEA
Highlights
- Annual average EBITDA of US$348MM and average annual free cash flow of US$235MM over 21 year life of mine (“LOM”)
- Annual production targeted at approx. 5.0 million tonnes of high grade, low impurity, iron concentrate grading ~65% iron with 0.52% V2O5 per tonne of concentrate
- Total operating costs of US$66/t of concentrate over LOM (freight to China included)
- Initial Capex estimated at US$574 million includes US$118 million contingency
- Payback period under 2 years
- 21-year LOM uses fraction of total resources
- Open pit mining operation with a LOM strip ratio less than 0.9:1
- Additional upside from the potential to expand development from the current North Zone Inferred Resources (507Mt) and South Zone Indicated (119Mt) and Inferred (89Mt) Resources
Iron and Vanadium Pricing Market Study
In late 2019 the Company had commissioned an Independent Market Pricing Study to review the expected credit that can be achieved for the contained Vanadium within iron concentrates. The study reviewed a value in use methodology based upon a review of the grade and concentrate chemistry from Mont Sorcier relative to other similar iron products and the study concluded that the concentrate from Mont Sorcier should receive a US$15/t premium to the Platts 65 price iron Index for the contained vanadium credits (based on a net attributable value using a long term V2O5 price of $7.25/lb). Since that time the outlook for premium high-grade concentrates has remained robust. Iron has seen peak pricing of over US$140/t for Fe62% with an additional premium for Fe65% typically being around a 20% premium to this price level. This premium is expected to be sustained in the market due to the significant environmental benefits. Equally, the metal price has flexed with transportation shipping rate increases. To fairly assess the potential scenario a long-term metal price in line with the Life of Mine estimate of 21 years has been adopted and at the same time this has been assessed using long term shipping costs. The Base Case metal price assumptions are outlined below.
Mineral Resource Estimate
The PEA is based on a mine plan derived from the North Zone Indicated Material of the Mineral Resource Estimate dated June 6, 2022, outlined below.
Mineral Resource Estimate used in Preliminary Economic Analysis
Notes to accompany the Mineral Resource Estimate:
- The independent and qualified persons for the Mineral Resource Estimate, as defined by NI 43-101, are Marina Iund, P.Geo., Carl Pelletier, P.Geo., Simon Boudreau, P.Eng. all from InnovExplo Inc. and Mathieu Girard P.Eng. from Soutex. The effective date is June 6th, 2022
- These mineral resources are not mineral reserves, as they do not have demonstrated economic viability. The Mineral Resource Estimate follows current CIM Definition Standards.
- The results are presented undiluted and are considered to have reasonable prospects for eventual economic extraction by having constraining volumes applied to any blocks using Whittle software and by the application of cut-off grades for potential open-pit extraction method.
- The estimate encompasses two (2) deposits (North and South), subdivided into 8 individual zones (7 for North, 1 for South).
- No high-grade capping was applied.
- The estimate was completed using sub-block models in GEOVIA Surpac 2021.
- Grade interpolation was performed with the ID2 method on 4 m composites for the North deposit and on 10 m composites for the South deposit.
- The density of the mineralized zones was interpolated with the ID2 method. When no density analysis was available, the density value was estimated using linear regression with Fe2O3 analysis. For the unmineralized material, a density value of 2.8 g/cm3 (anorthosite and volcanics), 3.5 g/cm3 (Massive sulfide formation) and 2.00 g/cm3 (overburden) was assign.
- The Mineral Resource Estimate is classified as Indicated and Inferred. The Inferred category is defined with a minimum of two (2) drill holes for areas where the drill spacing is less than 400 m, and reasonable geological and grade continuity have been shown. The Indicated category is defined with a minimum of three (3) drill holes within the areas where the drill spacing is less than 200 m, and reasonable geological and grade continuity have been shown. Clipping boundaries were used for classification based on those criteria.
- The Mineral Resource Estimate is locally pit-constrained for potential open-pit extraction method with a bedrock slope angle of 50° and an overburden slope angle of 30°. It is reported at a rounded cut-off grade of 2.30 % Weight Recovery. The cut-off grade was calculated for the concentrate using the following parameters: royalty = 3%; mining cost = CA$3.30; mining overburden cost = CA$2.45; processing cost = CA$3.62; G&A = CA$0.75; selling costs = CA$58.36; Fe price = CA$190/t; USD:CAD exchange rate = 1.3; and mill recovery = 100% (concentrate). The cut-off grades should be re-evaluated considering future prevailing market conditions (metal prices, exchange rates, mining costs etc.).
- The number of metric tonnes was rounded to the nearest thousand, following the recommendations in NI 43-101 and any discrepancies in the totals are due to rounding effects.
- The authors are not aware of any known environmental, permitting, legal, title-related, taxation, socio-political, or marketing issues, or any other relevant issue not reported in the Technical Report, that could materially affect the Mineral Resource Estimate.
Mining
The mine design is based only upon the current Indicated Resources contained in the North Zone alone and assumes standard open pit mining techniques of drill, blast and haul. Voyager developed a mine plan which processes 341.5 million tonnes of the current Indicated Resource base over a 21-year mine life at an average strip ratio of 0.87 to 1. Mining costs are estimated at US$2.03/t of material moved.

Metallurgy and Processing
The results of the test work to date have indicated that the production of premium high grade 65% magnetite iron concentrate with approximately 0.52% V2O5 can be achieved.
The processing plant designed for Mont Sorcier is forecast to be in line with similar projects in production locally and globally using standard equipment and technologies. The study envisages a conventional crushing and grinding circuit, with three stages of low intensity magnetic separation (LIMS). In addition to the flow sheet previously contemplated, this PEA includes a reverse flotation circuit. The reverse flotation circuit has been included so that the concentrate will have a sulphur content of approximately 0.1% which allows for sale in both Europe and China. The initial testing results support and indicate the viability of Sulphur removal performance.
Infrastructure
The site is located with access to all weather roads, water, low-cost grid hydro power and sufficient railway capacity to support project development with only modest infrastructure capital needs. The PEA incorporates expenditures required for additional infrastructure including auxiliary buildings, electrical grid connection, rail loading facilities at the mine site and unloading facilities at the Port of Saguenay. This also includes a new rail loop at the mine to improve loading efficiencies and a new rail spur to connect to the main line to the Port of Saguenay. For the PEA it has been assumed all concentrate production will be rail hauled to the Port of Saguenay for international shipment to China or Europe. Given the proximity to Chibougamau, no permanent camp is required for the anticipated permanent workforce.
In addition, the project will also include new tailing facilities in a location to the North of the open pit. The location of a Non-Mineralized Rock waste dump will be determined after consultation with local stakeholders and additional engineering and design.
Capital Costs
Upfront capital costs are estimated at US$574M, deemed in accordance with the requirements of the Association for the Advancement of Cost Engineering (AACE) International Cost Estimate Classification System Recommended Practice No. 18R-97 Class 5, with an estimated pay back of under 2-years with an estimated after-tax IRR of 43%. Upfront capital costs have been factored to allow for current inflationary pressures, anticipated changes in equipment sizing, an increase in rail spur length, estimated costs for enabling of construction of accommodation, and the addition of the reverse flotation circuit to the process plant.
The PEA capital cost estimates include a 15% contingency for mining equipment and Indirect costs and 30% for plant and infrastructure.
Upfront Capital Cost Estimate used in Preliminary Economic Analysis
Sustaining capital is estimated at approximately US$2.2/t over the LOM and is principally related to equipment replacement and future tailings dam raises during operation.
Operating Costs
The LOM operating costs are estimated at US$66.23/t CFR China. This value has been benchmarked against actual costs of Operators in the area.
Operating Cost Estimate used in Preliminary Economic Analysis
Overall Project Economics
The overall project shows potentially robust economic results for a preliminary mine plan using only Indicated Resources of the North Zone and leaves significant upside potential from the conversion of Inferred Resources in the future:
- An after tax NPV at 8% discount rate of US$1.6 Billion and IRR of 43%
- Potential 21-year mine life, with positive after-tax cash flow commencing in Year 1 of operation.
- Free cash flow post tax is estimated to be approximately US$235/annum over 21-year Life of Mine.
There is potential to enhance the value of the overall project through future upgrading of the North Zone Inferred Resource (507Mt) and the potential mining of the South Zone Indicated Resource (119Mt) and Inferred Resource (76Mt) that would be expected to improve the economics by potentially increasing the overall Life of Mine or open up the potential for future expansion in production capacity.

Proposed Development Program
In light of the robust PEA results, the Company has elected to continue on the basis of developing the North Zone as outlined as opposed to developing it in combination with the South Zone as previously contemplated. The Company is in the process of developing a detailed development plan and budget to determine the requirements to bring Mont Sorcier to a development decision as part of the ongoing Feasibility Study work that is currently underway.
