n Production guidance for 2026 is unchanged at 310-335kt Cu (GSe at 331kt) and

134-149koz Au (GSe at 141koz). Chapada cost guidance was lowered by

US$0.25/lb; however, group unit cost guidance remains unchanged at

US$1.90-2.10/lb (GSe at US$1.93/lb). Capex guidance increased modestly by

US$35mn to US$1.03bn on expansionary capex at Chapada (additional ball mill).

US$110mn (~US$7.5k/t Cu capex intensity) project is split into two components:
