B.C. court stops Mount Polley mine tailings dam use

A British Columbia court has halted operations at the Mount Polley mine's tailings dam, preventing further deposits of mine waste until July 1. The Supreme Court's injunction follows a legal challenge from the Xatsull First Nation, who are disputing the approval of a dam expansion. The First Nation is seeking to keep the pause in place pending a judicial review of the project's approval. The Mount Polley mine experienced a major tailings dam collapse in 2014. The B.C. government approved the expansion to manage spring runoff, citing expert reviews and First Nations consultation.
