Colombia's output of nickel, silver, platinum and coal fell last year, while gold production rose, the government said.
Nickel output fell 11% to 80.8 million lb in 2015 from 90.9 million lb a year earlier due to a two-week strike at Cerro Matoso, owned by BHP Billiton spinoff South32, the National Mining Agency said Wednesday in a statement.
Gold production rose 3.8% to 1.9 million oz last year from 1.83 million oz a year earlier, according to the agency.
Silver production fell 11.7% to 326,482 oz from 369,683 oz a year earlier, while platinum dropped 24% to 27,669 oz from 36,480 oz, the agency said.
Colombia's coal output fell 3.5% to 85.5 million mt in 2015, compared with 88.6 million mt a year earlier, as shipments were hampered by a strike by railway operator Fenoco and neighboring Venezuela's decision to close its borders, the agency said. Colombia is Latin America's largest coal producer.
