Vale has interrupted production at its Timbopeba mine and part of its Alegria mine after prosecutors ordered the evacuation of an area around the nearby Xingu dam, in the state of Minas Gerais.
The closures will reduce its output by 40,000 iron ore tonnes a day, it said. The company stopped traffic on the Fabrica Nova railroad, which usually transports iron ore produced at Usina Timbopeba.
Timbopeba was closed temporarily, reducing production by 33,000 iron ore tonnes a day, the company said.
Vale’s iron ore output totaled 68 million tonnes in 1Q21, 14.2% higher than in 1Q20, but down 5.5% compared to the 72 million tonnes average analyst estimate.
The year-on-year growth was in part attributed to the gradual resumption of halted operations in Timbopeba.
The miner maintains its full-year guidance of between 315-335 million tonnes of iron ore for 2021.
Vale said there is no “imminent risk” of the Xingu dam bursting.
