Preliminary data indicates that world mine production declined by about 1.8% in the first two months of 2019, with concentrate production declining by 1.3% and solvent extraction-electrowinning (SX-EW) by 4%.
Although a few countries experienced growth, this was largely offset by declines in two major producing countries, namely Chile and Indonesia.
Production in Chile, the world’s biggest copper mine producing country, declined by 6% mainly due to lower copper head grades.
Indonesian concentrate production declined by 50% primarily as a consequence of the transition of the country’s major two mines to different ore zones leading to temporarily reduced output levels.
After aggregated growth of 13% in 2018, production in the Democratic Republic of the Congo (DRC) and Zambia increased by 1.3% in the first two months of 2019 as reduced production at some mines partially off-set ramp-up output at other operations.
