The Peter Zeihan Podcast Series North Carolina's Silicon Mines: Leverage for the US? || Peter Zeihan
Dec 19, 2025
The discussion delves into the significance of North Carolina's high-purity silicon quartz mine for semiconductor production. It highlights the U.S.'s substantial role in supplying critical materials and emphasizes the multitude of advantages beyond just one mine. Peter also breaks down the intricate global processing of materials like copper, illustrating the complexities of supply chains. Notably, he points out U.S. monopolies in critical inputs and the challenges of completely reshoring semiconductor production, hinting at the staggering costs involved.

Episode notes
US Has Multiple Semiconductor Leverage Points
- A single North Carolina high-purity quartz mine provides critical silicon dioxide and ultra-pure material for crucibles used in chipmaking.
- But the mine is one of many leverage points across a massively distributed semiconductor supply chain.
Semiconductor Supply Chain Is Deeply Distributed
- Semiconductor production requires tens of thousands of distinct inputs and steps spread across many countries.
- No single country controls the majority of the supply chain, creating mutual dependencies and leverage.
China Leads Low-End Processing Only
- China dominates low-end processing but cannot reach the extreme purities required for high-end semiconductors.
- High-purity finishing often occurs in the United States, Germany, Japan, or Korea before re-export to China.
