Welcome to Highgrade's podcast on the world of natural resources. We kick off our podcast journey with a theme that goes to the very core of the extractives industry, to its heart. We explore the fundamental topic of mining productivity. Sounds boring? Think again: this is a window to what the industry has been, and what it will be. We talk about money, energy, people, robots, and much more. Come join us as we sit down with Dr. David Humphreys, resource economist extraordinaire.
