Copper producer Antofagasta said on Wednesday protests in Chile could cut its production by about 5 000 t, equivalent to less than 3% of third quarter output, due to delays in supplies and travel disruptions for workers.
The London-listed miner, which has four mines in Chile and employs about 19 000 people, kept its full-year forecast unchanged at 750 000 t to 790 000 t of copper this year, but said 2020 output would be lower at 725 000 t to 755 000 t.
