About Mount Sylvia Diatomite
Mount Sylvia Diatomite is an Australian producer of Molodri® and ACO certified diatomaceous earth (DE), sourced from a geologically rare freshwater lake-origin quarry in South East Queensland.
Why freshwater origin matters
Most commercial diatomaceous earth is sourced from marine or seawater deposits. Our DE comes from an ancient freshwater lake — formed when volcanic lava met a freshwater environment approximately 20 million years ago. The result is a mineral deposit with higher amorphous silica content, lower contamination, and a naturally occurring trace mineral profile that makes it genuinely suited to livestock and agricultural applications.
It is why our DE is ACO certified — the only certified DE input in Australia — and why Molodri®, our registered dry molasses supplement, has been used by Australian feed manufacturers and livestock supplement producers for years.
Who we supply
We work with feed manufacturers, agricultural distributors, and livestock operations across Australia and for export. We supply wholesale and trade accounts only.
