He has worked on mining transactions and projects in multiple jurisdictions. Prior to his appointment, Mr Henao served on the company's Board of Directors and stepped down from that position.

Adjustments to the ownership structure over 2024 and 2025 prompted a reassessment of executive roles and strategic priorities. Departing leaders will support a transition over the coming weeks.

Mr Henao stated:

"We remain committed to maintaining stability and advancing our core mission throughout this period of evolution. Our focus is on delivering value to our stakeholders while positioning Mineros for long-term success."

David Splett will step down as Chief Financial Officer effective January 2, 2026. Sergio Chavarria, currently Finance Manager, will serve as Interim Chief Financial Officer. Mr Chavarria has held senior finance roles with Mineros since 2018 and previously worked as Senior Audit Officer at Deloitte. He holds an MBA from EAFIT University and a degree in economics from the National University of Colombia.

Senior Management Appointments and Organisational Structure

The company is strengthening its technical and growth leadership with three new appointments who will report directly to the CEO. These positions are focused on technical and growth leadership.

The creation of these senior management positions follows the ownership structure adjustments mentioned earlier. The company has not disclosed further information about the responsibilities or backgrounds of these appointees. The timing of these announcements coincides with the CEO and CFO transitions.

Chairman of the Board Augusto Lopez commented on the leadership changes:

"We are pleased to welcome Daniel, María, and Carlos to their new roles, and to recognize Marcela and Sergio's long-standing contributions. These appointments strengthen our leadership team as we execute on our strategy."

The names María, Carlos, and Marcela appear to reference some of the new appointees.

Board of Directors Resignations

Andres Restrepo and Marco Izquierdo Llanos resigned as directors of Mineros S.A., effective November 18, 2025. The company thanked them for their service and contributions.

"On behalf of the Board, I would like to thank Mr. Londoño, Mr. Splett, Mr. Restrepo, and Mr. Izquierdo for their dedication and service."

The board resignations occurred on the same date as the CEO appointment. Ownership structure adjustments over 2024 and 2025 prompted the reassessment of executive roles and strategic priorities. The board changes occurred alongside the senior management transitions.
