Name of the Project
Matawinie mine and Bécancour battery material plant – Phase 2.

Location
The Matawinie graphite property is located north of Montréal, Québec, Canada, in Saint-Michel-des-Saints.

Project Owner/s
Aspiring strategic graphite supplier Nouveau Monde Graphite Inc (NMG).

Project Description
An updated feasibility study has indicated that Phase 2 is technically feasible and economically viable.

With a 25-year life-of-mine, the Matawinie mine will leverage the West Zone deposit for a nominal production of 105 882 t/y of graphite concentrate. 

The deposit will be mined using conventional openpit mining methods consisting of drilling, blasting, loading and hauling.

The site is considered concrete-ready for the start of construction upon a positive final investment decision, with several key contracts having been awarded, including process equipment, the dedicated powerline and the electrical substation. 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. The plant is expected to produce 43 334 t/y of micronised graphite by-product.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The Matawinie mine and Bécancour battery material plant have a pretax net present value, at an 8% discount rate, of $1.33-billion and an internal rate of return of 17.3%, with a payback of 5.8 years.

Capital Expenditure
The Matawinie mine and Bécancour battery material plant require initial capital expenditure (capex) of $1.33-billion.

Capex for the Matawinie mine is estimated at $415-million and for the Bécancour battery material plant at $911-million.

Planned Start/End Date
Upon a positive final investment decision, the Matawinie mine and Bécancour battery material plant could be built and could enter commercial production in less than three years.

Latest Developments
None stated.

Key Contracts, Suppliers and Consultants
