Vale triggers emergency protocol at Ouro Preto dam
Brazilian iron-ore miner Vale on Thursday said it had preemptively triggered an emergency protocol at its Forquilha IV dam which processes waste from its Fábrica mine near the historic town of Ouro Preto.
Vale said it had taken the decision for the protocol, which does not require the evacuation of nearby residents, in agreement with regulators after an anomaly was identified at the dam "during routine inspection".
