Antofagasta plc reported third-quarter 2026 copper production of 151,900 tonnes, up 7% quarter-on-quarter, as its Los Pelambres mine drew down inventories built up in the prior quarter and recovered from July's severe weather in Chile's Coquimbo region. Year-to-date output reached 436,900 tonnes, down 8.3% year-on-year, weighed by lower grades and recoveries at Centinela. The London-listed miner kept its full-year 2026 copper guidance at 625,000-655,000 tonnes. Citing persistently high global diesel prices, it raised full-year cash-cost-before-by-product-credits guidance to US$2.60-2.70 per pound from US$2.40-2.60.

TOP Nanometal Corporation, a Taiwan-based roll-to-roll vacuum sputtering manufacturer, has discontinued production of Indium Tin Oxide transparent conductive film with immediate effect. The company will convert its former Indium Tin Oxide equipment entirely to high-end sputtered-copper production, focusing on adhesive-free Flexible Copper Clad Laminate, copper-coated polyester film for transparent light-emitting-diode displays and thin copper films for flexible electrodes. TOP Nanometal attributed the decision to intensifying competition and narrowing profit margins in the Indium Tin Oxide film market, while customer demand and profitability were stronger in sputtered-copper products. SMM believes the closure shows that conventional Indium Tin Oxide film faces growing cost and profitability competition from copper-based conductive materials in certain flexible-electronics and transparent-display applications. The conversion will reduce the company’s demand for Indium Tin Oxide targets and indium feedstock, although its previous film capacity, output, target purchases and indium consumption were not disclosed.
