There is a lot of attention on domestic manufacturing in the United States these days. But for Turner Caldwell, who spent nearly a decade at Tesla, there’s not enough attention on the minerals and metals that sit at the very bottom of the supply chain.

To do that, his company is trying to automate almost every aspect of a mining operation imaginable.
