USD Index at 100.54 and CNY/USD at 6.6991 provided modest support for USD-denominated prices, lifting copper 3.19% to 6.8995 USD/lb while cobalt slipped 0.85% to 39780 USD/t amid the DRC supply squeeze. DRC copper-cobalt miners cancelled a 2000 t SMBS order and saw an 1800 t shipment withdrawn, doubling delivered sulfuric acid and SMBS costs via Dar es Salaam and prompting output cuts that directly tighten near-term cobalt availability. Freeport Indonesia’s Grasberg Block Cave now targets full production only in early 2028 after the September 2025 mudflow, holding output at 40-50% of prior levels and exposing ASX-listed copper names such as Sandfire Resources and 29Metals to sustained concentrate tightness.
