Our continuous investment enhances our ability to supply wet or dry silica sand. As a dedicated sand supplier, we package products to your specifications for local or overseas markets.

Our History as a Trusted Silica Sand Supplier
Sunstate Sands began mining in 1996. Initially, we fed a pilot plant producing 12,000 tonnes per year. This silica served foundry, epoxy, and coating industries. Success led to a new plant in 2001 with a capacity of over 100,000 tonnes. In 2015, a new purpose-built wet plant was commissioned, capable of delivering up to 500,000 tonnes per annum.

Years in business

tonnes per year
In 2006, Mayfairs Group acquired Sunstate Sands as one of many mine and quarry sites that formed part of a long-term plan to create a strong group of independent quarries and pits providing quality products to local (South East Queensland), national & global customers.
In 2025, Sunstate Sands was acquired by De Gunst Transport, marking a new phase of growth for the business. The acquisition strengthened Sunstate Sands’ operational capacity and longterm stability while maintaining its focus on the supply of high-quality industrial sands.
Today, we hold mining leases over 260 hectares. This ensures a long-term supply of high-grade silica. As your premium sand supplier, we own both the source and the processing plant. As a result, no middlemen means reliable delivery and exceptional value.
Competitive Advantages of Our Silica Sand
Our silica sand features unique gradations and high purity. This sets us apart as a sand supplier. Moreover, our modern equipment processes silica sand to exact specs. We supply wet or dry forms in bulk or packaged.
Importantly, our mining permits secure over 40 years of silica supply. On-site processing reduces costs. This makes us an efficient and reliable supplier for South East Queensland, Australia-wide and global clients.
Resource Overview
Our resource holds 15 million tonnes of high-quality product. It’s graded into very fine (below 212 microns, 20%), fine (212-600 microns, 70%), and coarse (above 600 microns, 10%). Chemical composition shows 99.8% SiO2 with minimal impurities.
Wet Plant Processing
Our purpose-built wet plant washes and screens up to 500,000 tonnes yearly. Installed in 2015 for $7 million, it separates raw material into six products. This includes glass sand with spiral processing.
