Ero Copper Corp is pleased to announce its operating and financial results for the second quarter of 2025. The company produced a record 15,513 tonnes of copper at its Caraíba Operations, with an average C1 cash cost of $2.07 per pound. The Tucumã Operation produced 6,351 tonnes of copper, achieving a 25% increase quarter-on-quarter. Gold production at the Xavantina Operations reached 7,743 ounces, with C1 cash costs and All-in Sustaining Costs (AISC) of $1,115 and $2,234 per ounce, respectively. The company reaffirms its full-year guidance at Caraíba, with updated guidance ranges reflecting the performance of the Tucumã Operation.

Full-year capital expenditure guidance remains unchanged at $230 to $270 million. The company expects to complete the Phase 2 drill program at the Furnas Project by year-end 2025.
