The Discovery Files
Podcast Description
What really makes a discovery?This isn’t another podcast about the next big deposit or the person who “called it.” This is a journey into the human side of discovery—the stories behind the core sheds, drill pads, and field maps. We talk to the people who make exploration work: core loggers, drillers, project geologists, senior geos, and everyone in between.Through honest, unfiltered conversations, we explore the emotions, lessons, failures, team dynamics, and quiet wins that rarely make it into the headlines. We ask: what does a truly successful exploration team look like? How much of discovery is science, and how much is intuition, collaboration, or even chaos?If you’ve ever wondered whether our industry really understands what drives discovery—or if we’re missing the bigger picture—this podcast is for you.Real people. Real stories. Real discovery.
