Ero Copper reports Q4 copper production of 19,706 tonnes

Optimization initiatives across the Company’s operating portfolio in 2025 contributed to record quarterly copper production of 19,706 tonnes and quarterly gold production of 13,837 ounces, representing production improvements of nearly 60% and more than 100% compared to Q1 for copper and gold, respectively. An additional 14,999 ounces of gold in concentrates were sold from the Xavantina Operations during Q4, the result of a year-long value-creation initiative that is expected to continue to augment gold production through mid-2027. Record full-year consolidated copper production of 64,307 tonnes, combined with gold production and gold from concentrate sales totaling 52,290 ounces, contributed to a quarter-on-quarter increase in liquidity of nearly $40 million. As a result, year-end liquidity totaled approximately $150M. In 2025, the Company completed nearly 50,000 meters of exploration drilling at the Furnas Copper-Gold Project and expects to publish the first preliminary economic assessment on the project in H1 2026. A further 50,000 meters of exploration drilling is planned in 2026 in support of accelerated engineering studies.
