Why are critical minerals essential for modern technology and national security?
Critical minerals fundamentally underpin everything that we do every day. It's in your phone, in your airpods, your screens, your laptops, everything that we use, how they're refined and how they're mined, that all happens in the background.
There's not that many massive markets left that have been sort of like largely untapped by technology, and mining sort of screams one of the largest markets in the world.
This is the intersection of geopolitical urgency and tech. Now we have technology that can actually go and disrupt this. But also there's a talent base, hard tech companies working in sort of dirty spaces, willing to go out in the fields. So now's the time to build this company.
It's a huge problem. We have to figure out how to address it. And that means investing in mining in the US.
How does Turner Caldwell’s experience at Tesla shape Mariana Minerals’ vertically‑integrated, software‑first approach?
Again.
It can take more than 15 years to permit and build a new mine in the United States, and yet nearly every modern technology we rely on, from smartphones to fighter jets to AI data centers, depends on a steady supply of critical materials. Today we're joined by Turner Caldwell, founder of Mariana Minerals, along with American Dynamism General Partner Aaron Pricewright and partner Ryan McIntosh. 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 demand our industrial future requires. We get into why this industry is so broken, what it actually takes to turn rocks into usable materials, and how the US can rebuild its capacity to mine, refine, and manufacture the things that matter most.

Why don't we get into what are critical minerals and why do they matter?
Critical minerals fundamentally underpin everything that we do every day. And that's why we're personally really excited about it. But it's not just aerospace, energy, renewable energy, battery energy storage systems, the massive growth in AI that's happened in the last twelve, eighteen, twenty-four months and defense, obviously. But it's also everything that we use every day, right? Like what's in your phone, in your airpods, your screens, your laptops. And so it really crosses Everything that we use. But where they're produced and how they're refined and how they're mined, that all happens in the background. And so it's something that really does need to be brought to the foreground, something that we need to support more and more of.
And it's a long chain to go from digging something up to go all the way through to something that can actually be deployed in an end product. And so excited to talk about that.
Well, I don't get into how do we turn rocks into batteries or magnets and why is that so important?
Yeah. So it starts with mining, obviously. Well, it actually starts with expiration. But you gotta find the rocks in the first place, which is hard to do. And there's a lot of awesome companies that are working on trying to condense that timeline. But once you do find them, you have to get that asset or that resource permitted to extract. You develop a mining plan, you have to mine it.
What are the main steps and challenges in turning raw ore into usable battery and magnet materials?
And when those rocks come to the surface, you have to separate ore from waste, which is something that is not as trivial as people might expect. And then you go through a concentration stage. So the ores will come to the surface, they'll be less than 1%, definitely less than 5% concentration, unless you have world-class deposit.
