Antofagasta said copper production fell slightly in the third quarter of the year, but the miner maintained its guidance for 2019, though said it expected softer output in its next fiscal year. Guidance for 2019 was maintained at 750,000 to 790,000 tonnes of copper with costs expected to be below $1.25 per pound. But in 2020 production was expected to be in the range of 725,000 to 755,000 tonnes of copper as grades decline at Centinela Concentrates before rising again in 2021, the company said. Copper production in the third quarter fell 0.8% to 197,000 tonnes quarter-on-quarter and gold production for the quarter dropped 10.7% to 77,600 ounces, as grades declined at the Centinela mine. Molybdenum production in the quarter was 2,900 tonnes, some 100 tonnes lower than the previous quarter. The company said the increase in civil unrest in Chile could potentially disrupt the delivery of supplies and the transport of employees and contractors to its operations, with the impact on production expected to be around 5,000 tonnes.
