In this episode of Hearts & Mines, David Beilby speaks with Marnie Finlayson, Managing Director of ASX-listed uranium explorer DevEx Resources. A minerals processing engineer by training, Marnie spent 17 years at Rio Tinto across iron ore, gold, uranium, battery metals and rare earths, culminating in the role of Managing Director of the company's battery materials business, and played a key role in implementing recommendations from Rio's landmark workplace culture review.

This is a candid, high-energy conversation covering Marnie's upbringing on a remote sheep station north of Kalgoorlie, why she walked away from a major ASX company to build a junior uranium explorer from scratch, what authentic leadership really looks like at the top, and how AI has become a genuine part of her leadership team. A warm, honest conversation from one of WA's rising resource sector leaders.
