Ero Copper Corp. (TSX: ERO, NYSE: ERO) ("Ero" or the "Company") is pleased to announce the next phase of its leadership succession plan, effective January 1, 2025. Co-founder and Chairman of the Board, Noel Dunn, will be retiring from the Company's Board of Directors (the "Board"). David Strang, co-founder and current Chief Executive Officer, will assume the role of Executive Chairman, and Makko DeFilippo, President and Chief Operating Officer, will be appointed as President and Chief Executive Officer and will join Ero's Board. Gelson Batista will succeed Mr. DeFilippo as Chief Operating Officer.

This leadership transition is part of the succession plan initiated by Ero's Board of Directors in January 2023 with Mr. Dunn's retirement as Executive Chairman. The Board and management team are confident that this evolution will continue to position Ero for long-term success and growth.

Noel Dunn, co-founder and Chairman of the Board, commented, "It has been a tremendous privilege   to   be   a   part   of   Ero   Copper   from   its   inception   to   the   high-growth   copper   producer   it   is today. As I retire from the Board, I remain immensely proud of what we have accomplished and am excited about the Company's bright future under Makko's leadership. I have seen firsthand Makko's dedication, expertise, and deep commitment to our values, and I am confident that Ero Copper is in exceptionally capable hands."

David Strang, co-founder and CEO, added, "Having guided Ero from its early days as a 20,000-tonne-a-year copper producer to what I anticipate will become a 100,000-tonne producer, and with a stable financial footing across three operations, the time is right for me to transition day-to-day leadership to Makko, who has been integral to our success. As Executive Chairman, I will remain actively involved in Ero's strategic direction, and I am confident that with Makko's strong leadership and vision, Ero will continue to prosper and grow. We have built a solid foundation, and I look forward to seeing the Company flourishing under his stewardship."

Makko DeFilippo, President and COO, said, "I am honored by the trust that Noel, David and the Board of Directors have bestowed in selecting me as Ero's next CEO. I am deeply committed to our values, and to continue serving our shareholders to ensure the responsible delivery of our growth objectives. Ero has endless potential and I am confident that with the support of our exceptional project and operational teams, we will deliver on the full potential of our assets to create exceptional value for all stakeholders."

Mr. DeFilippo joined Ero in January 2017 as Vice President, Corporate Development, where he played a key role in supporting the Company through its initial public offering in October 2017. He was promoted to President in January 2021 and assumed the additional role of Chief Operating Officer in March 2023. Over his tenure, Mr. DeFilippo has been instrumental in elevating several strategic initiatives, including the transformation of the Xavantina Operations from a non-core asset into a high-margin, core asset of the Company. He led the successful negotiation and completion of the $110 million streaming transaction with Royal Gold Inc. and was key in establishing the Company's partnership with Vale Base Metals on the Furnas Copper-Gold Project earn-in agreement, announced in July 2024. Additionally, Mr. DeFilippo guided the construction of the Tucumã Operation, which was successfully completed on schedule earlier this year. Mr. DeFilippo holds a M.Sc. in Metallurgical Engineering from the Colorado School of Mines and a B.Sc. in Geological Engineering from the University of Arizona.

Mr. Batista joined Ero in September 2024 as Senior Vice President, Operations, bringing with him over 25 years of extensive international mining experience.
