High Purity Quartz / Silica
The rock that runs the world
Quartz is one of the most widely used industrial minerals in the world.
Quartz-bearing formations such as quartzites, sandstones and granitic gneiss are primary sources of silicon (Si). However, impurities such as boron (B), phosphorus (P), aluminum and iron oxides can significantly impact its suitability for High-Purity applications.
Depending on the initial silicon dioxide (SiO₂) content—typically ranging from 95% to over 99%—and the level of trace contaminants, quartz can be processed into High Purity Quartz / Silica (HPQ) for a range of advanced industrial uses. For high-tech and ultra-pure applications, impurity levels must be reduced to extremely low thresholds.
Preliminary surface sampling has already returned High-Quality Quartz / Silica (HPQ) sand results, suggesting strong potential for achieving even higher purity levels at depth. This is supported by the Dorfner Anzaplan report (June 2021), which recommends further drilling to collect subsurface samples for additional purification testing. These results could potentially meet or exceed IOTA-grade standards.
Several development pathways exist for High Purity Quartz / Silica deposits. Over the past decades, demand for HPQ in advanced technologies has increased significantly, while global supply remains limited. The United States is currently the leading producer of HPQ sand.
Applications based
on quartz grade
Quartz is used in a wide variety of applications, depending on its ore format and purity. It is the future of industrial minerals.

High Purity Quartz / Silica (HPQ Sands)
Once reduced to sand size and purified, high-purity quartz (HPQ) serves key markets including fused silica, fumed silica, precipitated silica, silicon carbide, and low-iron glass. These applications span advanced technologies such as solar panels, semiconductors, EV components, coatings, and consumer products. Growing global demand, combined with limited high-grade supply, positions HPQ as a strategic and increasingly critical material worldwide.

Lump for Metallurgical Silicon "SiM-MG"
Prepared in lump form, high-purity quartz is the primary feedstock for silicon metal and alloys, essential to high-tech industries. As silicon demand grows, global production is expected to more than double by 2030, significantly increasing quartz needs. However, supply is constrained by limited high-quality deposits, positioning quartz as a critical material facing a growing structural supply gap worldwide.

Architectural Applications
The architectural qualities of pure natural quartz are highly valued by architects and designers. Its strength and durability, rated 7 on the Mohs scale, make it a premium material known for both performance and longevity. Baie Johan-Beetz quartz stands at the top of its class, distinguished by its pure white milky aesthetic and superior mechanical properties. Additionally, it may be possible to extract it in mega-blocks and cut it into slabs for a wide range of construction and design applications.

Manufacturing Residues
Quartz residues can be crushed and repurposed for a wide range of applications. These include use in concrete production, sandblasting, anti-wear flooring, and agglomerated countertops. This versatility enhances the overall value of quartz by minimizing waste and supporting sustainable practices, making it an efficient material not only in its primary use but also across various secondary industrial and design applications.
The High Purity Quartz Market
The High-Purity Quartz / Silica (HPQ) market is experiencing sustained growth, driven by increasing demand from advanced technologies such as semiconductors, solar photovoltaics, and electronics. The global market is projected to reach approximately US$2.3 billion by 2033, growing at an annual rate of around 7%, supported by the rapid expansion of digital infrastructure and energy transition initiatives.
At the same time, supply remains constrained, as only a limited number of deposits worldwide meet the stringent purity requirements for HPQ. This imbalance between growing demand and scarce High-Purity Quartz / Silica resources positions HPQ as a strategic and increasingly critical mineral for the global economy.
