No date has been set for the reopening of Vale S.A.'s mines in Sudbury, Ontario, which were closed following a fatal accident Sunday. The stoppage was made in order to conduct a general review of safety conditions at the mines. Vale continues to operate its processing facilities in the area using stockpiled ore. The mines were closed after a worker was killed at the company's Coleman Mine, the third fatality at Vale's Canadian mines in less than eight months.
