Hurricane Helene Impact on Spruce Pine Quartz Production
Hurricane Helene's landfall in late September 2024 severely disrupted the global supply chain for high-purity quartz in Spruce Pine, North Carolina. This location produces the majority of the world's high-purity quartz, a critical material used to create crucibles for melting polysilicon into wafers for semiconductors and solar panels. While mining operations were halted due to catastrophic local infrastructure damage and power outages, leading producer Sibelco restarted operations and shipments in early October, while The Quartz Corp worked to assess damage.

Facts (10)
- Established
Hurricane Helene dropped over two feet of rain on Spruce Pine, North Carolina, between September 24 and September 28, 2024, causing catastrophic flooding and infrastructure damage.
- Established
Spruce Pine is the primary global source of high-purity quartz, accounting for an estimated 70% to 90% of the world's supply.
- Established
High-purity quartz from Spruce Pine is essential for manufacturing fused-quartz crucibles, which are used to melt polysilicon for semiconductor wafers and solar panels.
- Established
Mining operations in the Spruce Pine district are primarily managed by two companies: Belgium-based Sibelco and Norway-based The Quartz Corp.
- Established
Both Sibelco and The Quartz Corp halted mining operations on September 26, 2024, in anticipation of and response to the hurricane.
- Established
Sibelco officially resumed mining operations and customer shipments at its Spruce Pine facility on October 10, 2024.
- Established
As of October 11, 2024, The Quartz Corp had not yet restarted operations, stating it was too early to assess a timeline due to local infrastructure damage.
- Established
Local transportation for mining exports was severely hampered by washouts on roads like I-40 and damage to regional rail lines.
- Emerging
Initial visual inspections by mine operators indicated that damage was largely concentrated on ancillary units and local infrastructure rather than the mines themselves.
- Emerging
Industry analysts estimate that current inventories of high-purity quartz may buffer the semiconductor industry for approximately four to six weeks of disruption.
