Mara Rosa turnaround

• Contractor transition reached planned capacity; material movement hit nameplate levels toward quarter-end, and improved roads and access supported entry into higher-grade areas.

• Plant reliability, throughput and recoveries improved; the new thickener shortened filtration cycles, restored tailings-disposal continuity and resolved H1 water-management constraints.

• 2027 annual production is expected at 80,000–85,000 oz, subject to the budget process; rainy-season and possible El Niño preparations are underway.

Costs and financial position

• FY AISC guidance remains $2,380–$2,500 per GEO despite inflationary pressure in Argentina.

• 2027 cost outcomes depend on production rates, budgets and metal-price-related costs; mitigation initiatives are being pursued across the business.

• Net cash/LTM EBITDA was ~0.10x at 30 September 2026.
