Australian Owned and Operated

About Us

We are a vertically integrated Australian owned and operated company that extracts, produces, transports and spreads natural agricultural and industrial minerals across Queensland and beyond.

Our Story

100% Australian owned and operated, supplying high quality agricultural and industrial minerals since 1979.

Miriwinni Lime and Gypsum (MLG) was founded by the Wilkins family during the 1970s after they identified a growing need to optimise the condition of their cane farm soils to improve crop yields. This challenge saw them secure their first limestone deposit at Mount Garnet in Far North Queensland.

Following this, the company expanded, first to service its neighbours and then established a more sophisticated supply, distribution, and spreading network in North Queensland. During this time other mineral deposits like dolomite, calcium silicate and gypsum were secured to supply the growing demand for sweeter soil.
In 2021 Australian Agricultural Minerals (AAM) purchased MLG and were provided the opportunity to continue the legacy of the Wilkins family. In 2023, MLG, under the guidance of AAM, remain committed to proudly source, supply and spread quality minerals that improve soil and crop performance across a wide variety of farming operations and other industrial industries of Queensland and beyond.
