ERO COPPER PUBLISHES 2022 SUSTAINABILITY REPORT

Ero Copper Corp. has published its 2022 sustainability report. 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.

"Our 2022 sustainability report highlights the company's commitment to creating value for all stakeholders through responsible mining and corporate citizenship," said David Strang, Ero's chief executive officer. "As the global decarbonization movement gains momentum and stakeholder interests converge, we firmly believe that upholding strong ESG principles and performance will translate into positive financial outcomes.

"We take immense pride in our position in the evolving copper supply landscape, where carbon-intensity of production is emerging as a defining factor. Consumers' growing preference for low-carbon goods, as well as the implementation of government policies and cross-border carbon taxes aimed at reducing greenhouse gas emissions, are driving this stratification. With approximately 85 per cent of Brazil's power sourced from renewable energy, we are proud to produce some of the lowest carbon-intensity copper globally and look forward to expanding our contributions to the green economy with the addition of the Tucuma project.

"Our commitment to sustainability extends beyond reduction of greenhouse gas emissions. At our Caraiba operations, we have made notable progress in aligning with the Mining Association of Canada's Towards Sustainable Mining standard. Additionally, we have made significant strides in (i) improving access to health care, (ii) providing support for the mental health of our work force, (iii) enhancing the diversity of our work force, and (iv) aligning with the Task Force on Climate-related Financial Disclosures.

"At Ero, we understand that sustainable practices are not only an ethical responsibility but also a catalyst for long-term success. We are resolute in our dedication to maintaining high ESG standards as we pursue a more sustainable future for all."
