Michael Haworth, Chairman of Marimaca Copper, commented:

“We would like to thank Petra for her valuable contributions as a member of Marimaca’s executive team over the last 2 years and, prior to that, as a member of the Board. She has been a core member of the team as the Company has commenced its transition from explorer to developer, and leaves behind an excellent foundation for Marimaca’s next phase of development. 

“We are very pleased to welcome José Antonio to the Team. His experience and commercial acumen will be exceptionally valuable during this next, critical phase of Marimaca’s journey to becoming a high-quality copper producer. The Company is rapidly de-risking the Marimaca Project and José Antonio’s leadership will be instrumental in the delivery of our next key milestones including permitting submissions, the planned Definitive Feasibility Study and strategic financing discussions.”
