Announcement PDF ASX:ARO ASX Announcement 7 August 2026 ABN 16 003 254 395 ALTORO METALS APPOINTS EXPERIENCED RESOURCES EXECUTIVE MYLES CAMPION TO THE BOARD Altoro Metals Limited (ASX: ARO) ("Altoro" or the "Company") is pleased to announce the appointment of Mr. Myles Campion as a Non-Executive Director of the Company, effective immediately. Mr. Campion brings more than 35 years of experience across the natural resources sector, having held senior roles spanning mineral exploration, resource analysis, fund management, equities research and project and debt financing. His career provides a unique blend of technical expertise and capital markets knowledge that will support Altoro as it advances its European critical minerals portfolio. Academically, he holds a Graduate Diploma of Business (Finance), an M.Sc. in Minerals Exploration from the Royal School of Mines in London, and a B.Sc. Honors in Geology from the University of Wales College Cardiff. Crucially for Altoro, Mr. Campion possesses extensive knowledge of the European zinc sector through his long-standing involvement with the Toral Zinc Project in León, northern Spain. The Toral Project and Altoro's flagship Novales Zinc Project in Cantabria are located approximately 150 kilometres apart within the same highly prospective metallogenic belt. This proximity provides Mr. Campion with a deep understanding of the regional geology, permitting framework, and operating environment. His proven experience advancing one of Europe's most significant undeveloped zinc projects is highly synergistic with Altoro's strategy to accelerate exploration and development activities across its Spanish assets. Commenting on the appointment, Altoro Metals Chairman Tony Wehby said: "We are delighted to welcome Myles to the Altoro Board. His combination of geological expertise, zinc sector experience, and capital markets knowledge will be a tremendous asset as we continue to advance our Spanish projects. Importantly, his extensive, hands-on experience with the Toral Zinc Project provides valuable regional insight and a deep understanding of the opportunities and challenges associated with developing zinc projects in northern Spain. We look forward to working with Myles as we accelerate exploration and development activities and continue building long-term value for our shareholders."
