Total copper exports hit $2.78 billion in April, down 4.1 percent from the same month in 2018, while lithium carbonate exports dropped to $49 million in April, their lowest value since December 2017, according to bank statistics.
The drop in export values follows a difficult first quarter for Chile's lithium and copper miners.
State miner Codelco and others were forced to suspend or scale back operations in January following unusually heavy rains in the country's northern desert, with operational issues and
falling ore grades continuing to weigh on output at Chile's top deposits.Chile exported lithium carbonate at an average price of $12,183 per ton in the first quarter, down nearly 1 percent from the previous period, according to a report from Bloomberg.
Chile is the world_s top producer of copper and second largest producer of lithium.
