Dam Safety Inspections (DSIs) are one of the measures in place for the safe management of our tailings facilities. DSIs are conducted annually by a third-party Engineer of Record for mine tailings facilities in order to to review the safe operation, maintenance and surveillance of the facility and to identify and make any recommendations.
