Silica sand is the most used commodity on the planet after air and water. It is the main ingredient in all types of glassmaking, including specialty solar panel and hightech glass, and foundry casting.

Arrowsmith North boasts a minimum 25-year mine life capable of producing more than 2Mt tonnes per year of highgrade (99.7% SiO2)* silica sand for export to the foundry, container glass and flat glass markets in Asia, with permitting well advanced, and will lead production. Muchea, located 50km north of Perth, is an ultra-high-grade (99.9% SiO2)* silica sand project capable of producing sand required for ultra-clear glass for solar panels and other high-tech glass applications. Boyatup, located 100km east of Esperance, is under development and capable of producing sand for the glass market. *Information relating to grades are extracted from releases to ASX on 28 August 2019 and 11 November 2022 (Arrowsmith North) and 18 October 2019 (Muchea).
