Sectors: Basic Materials Technology Sector rationale The company's primary revenue comes from manufacturing and selling raw and intermediate materials, specifically high purity quartz sand, polysilicon, and silicon wafers, which are sold to other manufacturers. While it serves the semiconductor industry, the production of polysilicon and quartz is explicitly listed as 'Basic Materials' (Polysilicon and raw materials) in the sector definitions. A secondary sector of Technology is included because the company manufactures silicon wafers specifically for semiconductor fabrication plants, which falls under 'Semiconductor Materials' within the Technology sector. Industries: Industrial Minerals Industrial Minerals Primary The company operates the Ausquartz Group Holdings division, which extracts and refines high purity quartz sand sold to producers of silicon and solar cells. This activity matches the description of mining and processing non-metallic industrial minerals like silica. Semiconductor Materials Semiconductor Materials Secondary The company produces and sells silicon polysilicon and silicon wafers, which are consumables and substrates used directly in semiconductor fabrication plants for integrated circuits.
