Résumé - Abstract
January 25, 2019. A tailings facility near the city of Brumadindo, Brazil, failed. Within 5 minutes, almost 12 million cubic metres of tailings had been released. Over 250 people were killed. It was a tragic event. One that forever changed the lives of those impacted. It also changed the way that the public, regulators, investors, and insurers regard the risks posed by mine tailings, and how the mining industry manages those risks. The ways in which Brumadinho will change how tailings are managed are still unfolding. Within days, a group of institutional investors led by the Church of England Pensions Board issued a call to action. That was the catalyst for the launch of the Global Tailings Review and the August 2020 release of the Global Industry Standard on Tailings Management. In parallel, the International Council on Mining and Metals undertook development of good practice guidance on tailings management, building upon the work of the Mining Association of Canada. Following the release of the Standard, ICMM developed a conformance protocol. Here in Canada, MAC has undertaken a review of its leading practice requirements and guidance for tailings management, with the goal of driving continual improvement. Because we must do better.
