The Global Quartz Question: What Comes Next?

Recent disruptions at the Spruce Pine operations in North Carolina, historically the world’s primary source of high-purity quartz (HPQ), have raised a critical question across global markets: what does this mean for the economy and technology supply chains?

The answer matters to everyone. Nearly 99% of global GDP depends, directly or indirectly, on semiconductors. The pace of the energy transition relies on solar photovoltaic cells. Both of these essential technologies depend on a steady supply of high-purity quartz, the feedstock from which silicon, and ultimately the modern digital economy, is built.

Now, with production at Spruce Pine’s leading producer, Sibelco, temporarily halted, the industry faces a potential bottleneck in the most critical raw material in the semiconductor supply chain. Even if operations resume within a few weeks or months, the event has highlighted just how fragile the world’s HPQ supply is.

The lesson from the Covid-era semiconductor shortage remains clear: scaling up production in this industry is not quick or easy. It takes weeks, even months, to transform raw quartz into polysilicon, and further time still to refine it into the ultra-pure silicon wafers that power everything from smartphones to electric vehicles to satellites. This is not a “just in time” industry; it’s a “get it right or the world slows down” industry.

That’s why the development of First Quartz’s domestic assets, including the Mount Rose and Armstrong sites — has never been more important. As nations push for secure, local sources of critical materials, First Quartz stands at the forefront of a new chapter in North American HPQ supply.

With global demand for semiconductors, solar energy, and advanced optics only accelerating, the path forward is clear: building resilience in HPQ supply is not just a matter of economic security, it’s a matter of technological independence.
