Summary

China controls 80-90% of critical metal refining, and that’s a big problem for the West’s data center, energy, and defense sectors, our guest Craig Tindale explains. Subscribe to the Blockspace newsletter! Welcome back to The Blockspace Podcast! Today, Craig Tindale, macro investor and former manufacturing consultant, joins us to talk about the critical mineral shortage and multi-trillion dollar problem facing the US data center, energy, and defense sectors. We dive into his "Critical Mineral Thesis," exploring how China secured 80-90% of the world's critical mineral refining capacity. Craig explains the "midstream matrix," the looming 25,000-tonne silver deficit, and why the US is like a "turtle on its back" after decades of outsourcing. We discuss if sound money can save a system that has lost its atomic backbone. If you’d like to read Craig Tindale’s work to learn more, you can find his seminal articles here: -Critical Materials: A Strategic Analysis -The Hard Bifurcation Subscribe to the newsletter! https://newsletter.blockspacemedia.com Notes: * China controls 80-90% of mineral refining. * 70% of silver production refined in China. * 25,000-tonne silver deficit in four years. * Large transformers have 4-5 year wait times. * Chinese firms borrow at 2-4% interest.

We've disconnected our financial system from our material system.

70% of silver production comes from refining out of China.

0:09.0

The copper of lead and zinc that's mined in Peru and Chile is sent to China

0:13.9

and then a silver slag is taken out and sent to the ingot makers in Switzerland and Mexico.

What the Chinese have done is put a dual licensing

0:24.2

system, only 44 of the companies in China are allowed to actually sell it. And only approved

0:31.5

applicants can buy the silver. There's eight ton of silver in an AI data center. There's 65 ton of copper in an AI data center. You can go through the list. It's like a guillotine. If the Chinese want to turn the whole thing off, they can turn it off.

Welcome back to the Blockspace Pod, brought to you by CleanSpark. The United States data center, energy, and defense sectors are facing a multi-trillion

0:56.1

dollar logistics problem that almost nobody is talking about, except for today's guest, Craig

1:01.5

Tyndall.

1:02.2

And Mr. Tyndall should know a thing or two about the problem because as he admits on the podcast,

1:06.3

he kind of helped create it.

1:08.0

Mr. Tyndall served as a liaison and consultant for Western firms that

1:12.7

were looking to outsource manufacturing capacity to China during that transition that took

1:17.3

place from roughly the 60s to the 2000s. As a result, China now controls 80 to 90% of all

1:25.0

of the refining capacity for the critical minerals and metals that are absolutely

1:29.2

essential for not just the AI boom, but also for energy systems across the United States

1:34.8

and critical defense systems. In this podcast, we break down how this transition happened,

1:41.0

how it was really allowed to happen is a better way to put it, and what it means

1:45.0

for the current AI boom in the U.S. and how it might end up derailing deployments and popping

1:50.5

the whole bubble altogether. This pod fuses a bunch of the topics that we talk about on the

1:55.7

Blockspace Pod from data centers to energy and also has a big macro focus. I've really excited to release this one to
