In 2014, a tailings dam at the Mount Polley copper and gold mine in British Columbia failed as a result of an unstable foundation, sending 24 million cubic metres of slurry into the surrounding waterways. A year later, the Samarco mine’s tailings dam failed as a result of seismic activity combined with structural defects and other issues.
