Another hill to climb for Copper Mountain

摘要

Operational issues at the Copper Mountain mine in B.C. are hounding Copper Mountain Mining (CUM-T). The latest technical glitch involved a failed transformer - one of the two that power the semi-autogenous grinding (SAG) mill motors at the mine. The company said on May 16 that coils in the transformer had broke down, although why they failed isn't clear. To try to minimize the impact on production, a transformer from a ball mill was transferred to the SAG mill to get it back into production. But production will be somewhat muted for a few weeks.
