Collective is also pleased to announce that Mr. Josué Romanos has been appointed as Vice President, Projects, effective immediately.

To ensure the exploration adit and future construction is delivered responsibly and on budget, we are pleased to welcome Josué Romanos as Collective Mining's new Vice President, Projects. Josué's decades of experience managing and delivering several multi-billion-dollar capital projects will be a significant asset as we continue to build a world-class company grounded in operational excellence and responsible development." Exploration Adit – Progress Update The exploration adit is a key component of the Company's strategy to advance its understanding of the Apollo system and the broader Guayabales Project from underground. Since announcing the Company's plan to construct an exploration adit on March 11, 2026, considerable progress has been made on the workstreams required to support development of the project.

Detailed engineering studies and execution plans have progressed, and the Company is now advancing through the relevant permitting track with an increased focus on operational readiness ahead of the commencement of construction. As part of this preparation work, the Company has completed various early activities, including completing the construction of an explosives storage facility, which has been inspected and approved for compliance by the relevant authorities. The exploration adit will provide underground drilling access, enhance the Company's ability to advance the project's geotechnical and hydrological characterization and provide access for the future collection of metallurgical bulk samples, all of which will be important in supporting future project studies.

Appointment of Vice President, Projects Mr. Josué Romanos is a senior projects executive with more than 30 years of experience in the energy and infrastructure industries in Colombia. He spent over 15 years at Ecopetrol, Colombia's national energy company, most recently as General Manager of Projects, where he led the engineering, construction, commissioning and quality assurance of a multi-billion-dollar capital portfolio and served on the company's investment committee. Earlier in his career, he held operations and commissioning roles at BP Exploration and PetroSantander across major projects in Colombia.

Mr. Romanos is a Petroleum Engineer from Universidad de América, with a postgraduate specialization in Gas Engineering from Universidad Industrial de Santander. Mr. Romanos' appointment strengthens Collective's in-house project execution capabilities as the Company advances the Guayabales Project through increasingly detailed technical, permitting and operational readiness workstreams.
