Hurricane Helene Blow for US Quartz Mining & Chip Supplies

Flooding in North Carolina’s Spruce Pine, a small town responsible for up to 90% of the world’s ultra-pure quartz, has brought quartz mining operations to a halt.

While this may not sound overly catastrophic, ultra-pure quartz is essential for manufacturing the silicon chips that power everything from smartphones to solar panels.

Spruce Pine’s unique quartz is used to produce the crucibles needed to make high-grade silicon, a fundamental material in semiconductor production. While there are alternative quartz sources in Russia, Brazil, India and China, none match the purity, volume, or accessibility of the Spruce Pine supply.

The reliance on this one location means that any disruption, like the one caused by Hurricane Helene, can have ripple effects on a global scale.

Immediate impact on mining operations

Sibelco, the Belgium-based mining conglomerate operating in Spruce Pine, temporarily halted operations ahead of the storm.

While the company’s initial assessments revealed only minor damage to facilities, the full extent of the disruption is still unclear. Meanwhile, The Quartz Corporation, another major quartz supplier in the area, has stated that it is too soon to determine how long it will take to restore production.

The region was hit hard by the hurricane, with widespread flooding, power outages and damage to infrastructure, all of which complicate recovery efforts. While Sibelco has reported progress in its recovery plans, both mining companies will need time to get back to full capacity.

This disruption comes at a time when the demand for advanced chips is already surging, driven by the growing need for AI servers and electronics.

In a statement, Sibelco said: "Hurricane Helene has significantly impacted North Carolina, USA and the Spruce Pine community has been hit particularly hard.

"The hurricane has caused widespread flooding, power outages, communication disruptions and damage to critical infrastructure in the area. Many people in the area, including our employees and their families, are facing displacement and significant disruptions." 

The company has since announced a US$1mn donation to the recovery of Spruce Pine and has established the Sibelco Spruce Pine Foundation. 

“We are committed to supporting the communities where we operate and this donation reflects our dedication to the Spruce Pine area,” adds Hilmar Rode, Sibelco CEO. “Through the Sibelco Spruce Pine Foundation, we aim to ensure that our contributions have a lasting impact.”  

Quartz mining disruption 'will have ripple effect'

The disruption of quartz mining in Spruce Pine is likely to have knock-on effects throughout the semiconductor supply chain. While major silicon wafer manufacturers like GlobalWafers, Siltronic and Sumco have stockpiles that can last between three and eight months, any prolonged mining delay could lead to a shortage.

Analysts from SemiAnalysis note that current inventories act as a buffer to the disruption, but if mining doesn’t resume before stocks run low, the industry could face a supply crunch, with the potential for rising prices.

Furthermore, transport routes in the region have been damaged, which may also delay quartz deliveries to manufacturers.

"The flooding of North Carolina’s quartz mines makes one thing very clear: the semiconductor industry needs to diversify its supply chain and invest in resilience," asserts Mohammad Saim, Global Procurement & Supply Chain Leader at Philips Healthcare.

"Relying too heavily on a few regions for critical raw materials like quartz is a recipe for disaster, especially in an era of climate and geo-political uncertainty. 

"Companies need to explore alternative sources of quartz, invest in sustainable mining practices and develop more resilient logistics networks." 

As chipmakers brace for the potential fallout from this disruption, the event serves as a stark reminder of how interconnected and delicate the foundations of modern technology can be.

Without swift recovery, the storm could have lasting effects on chip availability in industries worldwide.

About ultra-pure quartz

Ultra pure quartz, containing 99.997% silicon dioxide, serves as a foundation for semiconductor manufacturing and high-tech industries. The material occurs in pegmatite deposits, with notable sources in North Carolina, USA and Spruce Pine region. Mining involves extraction through open-pit methods, followed by crushing and processing to remove impurities.

The refinement process utilises chemical leaching and heat treatment to achieve parts-per-billion levels of purity. Processors subject the raw quartz to multiple cleaning stages to eliminate traces of aluminium, lithium, and sodium.

Industries employ ultra pure quartz in the production of silicon wafers, optical fibres, and photovoltaic cells. The material forms crucibles for growing silicon ingots used in computer chips. Telecommunications networks rely on ultra pure quartz in fibre optic cables. The photovoltaic sector uses the substance to manufacture solar cells.

The market for ultra pure quartz continues to expand with the growth of electronics manufacturing and renewable energy sectors.
