It can take more than 15 years to permit and build a new mine in the United States - yet nearly every modern technology we rely on, from smartphones to fighter jets to AI data centers, depends on a steady supply of critical minerals.

In this episode, Erik Torenberg is joined in the studio by Turner Caldwell, founder of Mariana Minerals, along with American Dynamism general partner Erin Price-Wright and partner Ryan McEntush.

Turner spent nearly a decade at Tesla, working his way upstream from factory design to battery materials and mining. Now, he’s building a new kind of mining and refining company - vertically integrated and software-first- designed to meet the demands of our industrial future.

We get into why the industry is so broken, what it actually takes to turn rocks into usable materials, and how the U.S. can rebuild its capacity to mine, refine, and manufacture the things that matter most.
