Responsible Mining

NMG has integrated innovative environmental initiatives into the design and operational model of the Phase-2 Matawinie Mine to limit potential impact on the natural and human milieu. The Matawinie Mine Project was submitted to the regulatory environmental procedure at the Government of Québec and to public consultations via theBureau d’audiences publiques sur l’environnement (“BAPE”). Following a rigorous environmental review complementary to the BAPE’s analysis, the Québec Government issued a ministerial decree on February 10, 2021, authorizing NMG’s Matawinie Mine.

NMG has put forward innovative design criteria by prioritizing the desulphurization of tailings, the gradual backfilling of the pit, and the co-disposal of waste rock and tailings. Field-scale cells demonstrated in real conditions the performance of this innovative environmental method and helped calibrate the parameters with respect to the performance of the tailings co-disposal objectives design including preventing sulfide oxidation and mine water contamination.

Proactive environmental management at the Matawinie site enables the advancement of initiatives in support of progressive reclamation, water protection, biodiversity stewardship, air quality, and energy efficiency.
