High Purity Quartz / Silica
The Smart Mineral
the World Depends On
Quartz/Silica 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 sand) for a range of advanced industrial uses (the Baie-Johan-Beetz deposit averages 99.6% SiO₂ at the surface). For high-tech and ultra-pure applications, impurity levels must be reduced to extremely low thresholds.
Preliminary surface sampling has already returned High Purity 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 Spruce-Pine deposit located in the United States, is currently the leading source for producing HPQ sand.

High Purity Quartz /
Silica (HPQ sand)
Quartz is used in a wide variety of applications, depending on its ore format and purity. It is the future of industrial minerals.
-
Used in crucibles for polysilicon production, semiconductors, batteries, optical fiber, and advanced glass applications, fused silica is one of the fastest-growing HPQ markets. Demand is accelerating with solar and semiconductor expansion, while limited global supply and strict purity requirements make high-purity quartz an increasingly strategic material worldwide.
-
Used in paints, adhesives, cosmetics, silicone rubbers, and pharmaceuticals, fumed silica is a high-value specialty market driven by performance-critical applications. Demand continues to grow through advanced coatings, EV-related materials, personal care products, and industrial applications where exceptional purity, consistency, and reliability are essential.
-
Used in toothpaste, tire reinforcement, food additives, and animal-feed applications, precipitated silica benefits from strong structural demand. Growth is supported by the adoption of green tires, increased mobility, and steady consumer-product consumption. This large-scale industrial market offers long-term demand visibility and broad commercial applications.
-
Used in advanced ceramics, high-temperature materials, power electronics, and semiconductors, silicon carbide is a rapidly growing advanced materials market. Demand is accelerating alongside electric vehicles, electrification, and energy-efficient technologies, making high-purity quartz an increasingly strategic feedstock for next-generation industrial and semiconductor applications.
-
Used as ultra-clear cover glass for solar panels and high-performance glass applications, low-iron glass is one of the fastest-growing end markets for high-purity silica. Demand continues to rise with global solar expansion, while manufacturers increasingly require premium-quality silica to ensure clarity, efficiency, and long-term durability.

Lump for Metallurgical Silicon ‘’SiM-MG’’
Used as the primary feedstock for silicon metal and silicon alloys, High-Purity Quartz/Silica plays a critical role in semiconductors, solar technologies, batteries, and other advanced industrial applications.
Silicon metal is also essential for producing polysilicon, a key material used throughout the global high-tech and clean-energy sectors.
Global silicon production is expected to more than double by 2030, significantly increasing demand for High-Purity Quartz/Silica. However, only a limited number of deposits can meet the strict chemical and physical requirements required for furnace-grade applications, creating growing supply constraints in an increasingly strategic market.

Architectural Applications
Used in architectural and design applications, natural quartz is valued for its strength, durability, and timeless aesthetic appeal.
With a hardness of 7 on the Mohs scale, quartz is widely used in premium interior and exterior surfaces where long-term performance and visual quality are essential.
The Baie-Johan-Beetz quartz stands out for its pure white milky appearance and exceptional mechanical properties. It can potentially be extracted as mega-blocks and cut into slabs for high-end construction and design applications, while quartz granules are also in demand for engineered stone surfaces.

Manufacturing Residues
Used in a wide range of industrial and construction applications, quartz manufacturing residues can be crushed, processed, and repurposed into valuable secondary materials.
Their durability, hardness, and mineral consistency make them suitable for both structural and surface-performance applications.
Quartz residues are commonly used in concrete production, sandblasting, anti-wear flooring, and agglomerated countertops. This approach supports material optimization while creating additional value streams from the quartz manufacturing process.
Located in Québec, our Johan-Beetz deposit represents a rare opportunity to develop a large-scale, High-Purity Quartz/Silica resource aligned with growing global demand.
