EMC2025 is shaping up to be a landmark event for exploration leaders—and our keynote speakers set the tone for what’s to come. The EMC is an invite-only members event comprising two days of meaningful discussions and cross-sector insights. The theme for 2025 has been developed in association with our member comprised advisory committee and is focused on the theme: Exploring Exploration – Where Does It Start? Where Does It Stop?  This topic will be explored through subthemes, including time, uncertainty, and collaboration.   

EMC2025 welcomes a keynote speaker who is shaping the future of mineral exploration through leadership, innovation, and collaboration. Marina Costelloe of Geoscience Australia bring decades of experience and a shared commitment to redefining how, when, and why we explore. These keynotes will open discussions on how national geoscience programs are enabling smarter, faster, and more strategic exploration outcomes across Australia.
