In the North, some mines risk leaking acid if the permafrost melts, while across Canada heavier rainfall will add strain to tailings dams and a lack of it could throw operations.
While no strangers to extreme weather, the growing risks from climate change are forcing the mining industry to take a hard look at their methods, and how to prepare for the worst. Many of the most prudent actions to minimize risk are, however, also more costly, meaning that while some have taken them on, not everyone has followed suit.
