High Grade Silica Quartz


Australian Silica Quartz Group, (ASQ) has identified a strategic opportunity to be an early mover into the expanding high grade silica sands and high purity hard rock quartz markets. To this end the company has been actively targeting and securing areas containing historically reported naturally occurring higher grade silica sands and hard rock quartz within Western Australia and Queensland.

The value of Australia's natural high grade silica resources and associated export markets are internationally recognised and the opportunity to secure these assets and be part of this emerging and expanding sector marks an important stage in the company's development.

Silica is found in nature in the form of hard rock quartz and naturally weathered sand. It is one of the most plentiful naturally occurring minerals on the Earth. Naturally occurring high grade silica sand is, however, relatively rare and it is this high grade silica that the company is targeting.

The uses of silica are extremely diverse and there are a number of established and emerging markets for varying grades of silica sand and quartz products. High grade silica sands where the silica component is greater than 99.5% SiO2 are  used in the glass, LCD, TFT, ophthalmic, ceramic and other industries.

ASQ has a number of projects targeting high grade silica sand and hard rock quartz that are currently being evaluated and progressed. The work underway on these projects consists of historical data review, deposit targeting and identification, representative sample drilling, infrastructure assessment, marketing and identifying off take opportunities. 

Key to the company's vision to add value to the silica and quartz projects is the Company's ongoing research and development project. This R & D work is aimed at increasing the purity of the silica from the company's silica sand and quartz hard rock assets to produce a >99.997% ultra high purity quartz to meet the industry IOTA standard for quartz and feed into the increasing demand. 


Ultra high purity quartz has been heralded as a critical mineral and is required to feed the increased demand for green tech and high tech applications. More specifically ultra high purity quartz is used in: 

  • semiconductors
  • solar PV cells
  • fibre optics, medical and lighting industries

Additionally the silica sand market is a growing market and international demand for existing Australian silica sand products is increasingly high and the quality is well regarded. 

Traditionally the Australian silica market has been dominated by Japanese trading houses operating as private Australian companies and supplying the South East Asian markets.

Some of the larger companies currently utilising Australia’s high grade silica resources include…

  • Mitsubishi (Australia) 
  • Taiwan Glass Industry (China and Taiwan)
  • Toyota & Tochu Partnership (Australia, Indonesia, Japan) 
  • Xinyi Golden Ruite Quartz Materials (China)
  • Zhuzhou Kibing (China)
