Planning for closure : Porcupine Gold Mine’s mine closure program Stevens, C.J.; Sulatycky, T.; Small, C.A.; Götz, L.; Taillefer, R.T.; Burke, L.E.
This paper describes the closure program that is underway by Goldcorp Canada Ltd. at their Porcupine Gold Mines (PGM) operation in Timmins, Ontario. As part of the mine property acquisitions, PGM made a corporate commitment to work with the communities and other stakeholders to close out the legacy sites while PGM mines are in operation. This led PGM to institute a closure planning program that involved assessing the environmental and safety risks associated with each legacy site and then prioritizing and scheduling detailed site investigations, closure options development, closure plan submissions, and preliminary to detailed engineering design through to construction. The closure program considers all the PGM sites and, where possible, incorporates closure measures between sites such as the consolidation of tailings or utilizing historical tailings as paste fill material at another underground mine.
