Chile's Q3 copper production fell to 1.16 mln tonnes, down 12% YoY and 8.7% QoQ, the lowest quarterly total on record since end-2006, the Chilean National Institute of Statistics (INE) said. Accidents, adverse weather and declining ore grades disrupted mine operations. Production in the first nine months slid 8.6%; full-year output could hit a multi-decade low. Chile supplies more than one-fifth of global mined copper, and the decline is tightening global supply as electrification-related demand
