Freeport reported that the Eastern Java smelter restarted in late August 2026 and is ramping up. Mill throughput averaged 140,000 metric tons per day in the third quarter, about 67% of pre-incident levels; the timing of gold sales deferred about 60,000 ounces from the quarter into the fourth quarter, weighing on by-product credits, while consolidated unit net cash costs are expected to be about 5% above the July estimate of $2.00 per pound of copper.
