A small Australian family mining business with a big first-mover opportunity
BSiO₂ Pty Ltd (ABN 74 682 041 158) mines, processes and distributes Diatomaceous Earth — scientifically known as Biogenic Amorphous Silica — from our deposit in Far North Queensland.
The deposit contains in excess of 10 million tonnes of high-grade diatomaceous earth reserves with minimal overburden, and has over 150 known applications spanning agriculture, food manufacturing, industrial safety, construction, health and wellness, and emerging technologies.
BSiO₂ is committed to unlocking the full potential of diatomaceous earth as an environmentally friendly resource that can revolutionise the way we approach construction, agriculture, food manufacturing, and environmental management.
Biogenic Amorphous Silica
Mining Far North QLDOur mission is to leverage the unique properties of DE in sustainable applications — green concrete, geopolymers, ecological land-to-ocean solutions. A natural mineral with a near-zero processing footprint.
We invest in independent laboratory certification from Australia's leading analytical facilities — Simtars, Agon Environmental, and HRL Technology Group — so our customers have documented proof of quality.
We acknowledge the Goondaloo – Warrungnu people of the Girringun region as Traditional Custodians of the land. We are committed to listening, learning, and improving how First Nations voices are heard in the minerals sector.
