Ero Copper Corp. reaffirmed consolidated production guidance for the year 2025. Consolidated copper production for 2025 is expected to increase sequentially each quarter, with full-year production projected to range between 75,000 and 85,000 tonnes.

At the Tucumã Operation, production is anticipated to increase sequentially throughout the year, with higher mill throughput volumes expected to offset a gradual decline in processed copper grades. At the Caraíba Operations, the Company achieved targeted mining rates at the Pilar Mine in March 2025 and completed the mobilization of a second underground development contractor during the quarter. As a result, higher mined and processed tonnage is expected to be sustained for the remainder of the year.

At the Xavantina Operations, the Company is also reaffirming production guidance of 50,000 to 60,000 ounces with higher processed tonnage and improved gold grades projected to support increased gold production and lower unit operating costs through the balance of the year.
