Verified Purity.
Secured Supply.
Delivered to Asia.
99.99% SiO₂ purity verified per batch. 10 million MT secured reserves. Direct mine-to-port export from Sri Lanka to Asia.
One of Asia's Highest-Purity Quartz Sources
Sri Lanka's geological profile makes it one of the world's premier sources of high-purity vein quartz. Independent laboratory analysis confirms SiO₂ content reaching 99.99% — a level that meets or exceeds the requirements of semiconductor crucible manufacturing, photovoltaic cell production, and optical fiber applications.
Max Minerals operates its own mining sites in Southern Sri Lanka, with full mining rights over an estimated 10 million metric tonnes of vein quartz reserves. Raw material is extracted from our controlled sites, processed at our Embilipitiya facility, and exported via Hambantota Port — giving buyers complete supply chain transparency from extraction to container.
