October 31, 2024

Vancouver, British Columbia – Ero Copper Corp. (TSX: ERO, NYSE: ERO) ("Ero" or the

“Company”) is pleased to announce the publication of its 2023 Sustainability Report (the

"Report"), titled Born in Brazil, Built for Tomorrow . This Report provides an update on the

Company's strategy, practices, performance and management approach to key environmental,

social and governance ("ESG") topics. The Report is available on the Sustainability section of

Ero's website (www.erocopper.com).

"Our 2023 Sustainability Report showcases our commitment to responsibly producing the

metals essential for global decarbonization," said David Strang, Ero's Chief Executive Officer.

"With our operations rooted in Brazil, we benefit from access to electricity generated from

approximately 85% renewable energy sources. This allows us to produce lower carbon-

intensity copper that contributes to a cleaner, more sustainable future.

"Driven by our responsibility to operate sustainably, we are also deeply invested in the well-

being of our workforce and the communities in which we operate. Key initiatives, such as the

renovation of the Curaçá Valley Polyclinic and educational programs like Project Hope,

underscore our commitment to local development, health, and safety.

"Sustainability is at the heart of our business strategy, and we remain dedicated to creating

value for all stakeholders as we Build for Tomorrow."
