- Australian Silica Quartz Group Ltd Australian Silica Quartz Group Ltd (ASQ.AX) is an Australia-based minerals exploration company focused on acquiring, exploring, and developing hard rock quartz and high-grade silica sand properties, alongside gold, nickel, copper, platinum group elements, and bauxite deposits. The company holds extensive tenements covering over 340 square kilometers in Queensland and Western Australia, including the flagship Quartz Hill Metallurgical Grade Silicon (MGSi) project with a JORC 2012 Mineral Resource of 17.3 million tonnes at 99.04% SiO2; high purity quartz prospects at White Springs, Douglas Range, Quartz Blow Creek, Pandanus Creek, Mount Cook, and Mount Juliet in Queensland, where rock chip samples have assayed up to 99.99% SiO2 after processing; the Seabrook hard rock quartz project in Western Australia with grades up to 99.98% SiO2; silica sand projects at Albany White Hill (11.6 million tonnes inferred resource at >99.9% SiO2 and <50 ppm Fe2O3) and Gingin via a joint venture with Urban Resources; the Koolyanobbing Metals Project spanning 408 square kilometers prospective for gold (with high-grade intercepts including 2m at 14.2 g/t Au), nickel, copper, and lithium; the South Stirling Ni-Cu project; a joint venture with HD Mining & Investments for bauxite exploration in the Darling Range (71.3 million tonnes inferred resource); and a royalty on bauxite sales from the sold Bauxite Alumina Joint Venture. ASQ conducts ongoing research and development for high purity quartz processing, including hot chlorination trials for crucible-grade products suitable for semiconductors and photovoltaics, and maintains a scoping study for the Albany silica sand export operation targeting 0.5-1.0 million tonnes per annum. Founded in 2006 and headquartered in Subiaco, Western Australia, the company operates solely in Australia across the industrial metals and mining sector, serving markets for metallurgical silicon, polysilicon, solar panels, specialty glass, and clean energy materials. Recent developments include the termination of a heads of agreement with Quinbrook Infrastructure Partners in June 2025 for Quartz Hill offtake following a scoping study that identified quartz grades suitable for blending rather than standalone use in polysilicon production, though Quinbrook remains open to future arrangements on other ASQ quartz assets; high-grade gold discoveries at Koolyanobbing with Phase I and II drilling confirming shallow mineralization including 1m at 27.7 g/t Au and nugget recoveries totaling 20.8 grams at the Emu target, prompting active partner searches for joint ventures or funding; metallurgical testwork upgrades at Quartz Hill yielding products up to 99.40% SiO2 with reduced iron and aluminum impurities; ongoing high purity quartz R&D demonstrating crucible-grade potential; and cash reserves of $837,000 as of June 2025 supported by unencumbered property assets valued at $3.25 million listed for sale, with no debt.
