Proposed B.C. mine plans to reduce water content in waste but still use tailings dams

KGHM International’s proposed Ajax copper and gold project will be one of the first tests of the B.C. government’s approval of waste storage for large open pit mines after the Mount Polley mine dam failure in 2014. The company, whose parent is Polish company KGHM Polska Miedz SA, plans to submit its project application early this month for review by the B.C. government. It will kick off an 180-day environmental assessment.
