Our History
Our Journey Through the Decades
For over 60 years, Mudgee Dolomite & Lime has been a cornerstone of quality and reliability in the Mudgee region. Founded on family values and driven by a commitment to excellence, our story is one of growth, innovation, and strong community ties. From humble beginnings at Mt. Knowles to becoming a trusted supplier across multiple industries, our legacy is built on hard work, integrity, and a passion for delivering premium products.

A New Beginning
William Murdoch purchased WJ Murdoch at Mount Knowles, formerly operated by BHP, marking the beginning of the Murdoch family’s legacy in mining and mineral processing.

Family Business Takes Shape
Robert and Brian Murdoch took over the family business, transforming WJ Murdoch into a registered company. This era saw growth and a stronger foothold in the regional market.

Expansion & New Opportunities
The Murdoch family acquired Mudgee Dolomite & Lime Pty Ltd, previously known as Industrial Minerals Australia. This strategic move expanded their product range and strengthened their reputation in the agriculture and construction industries.

The Next Generation
Robert and Stephen Murdoch assumed full ownership of the company, rebranding it as RK Murdoch Pty Ltd, trading as Mudgee Dolomite & Lime. This father-and-son duo continues to drive the business forward with a commitment to quality, sustainability, and community support.

A Trusted Local Supplier
Now a leading supplier of dolomite, lime, and industrial minerals, MDL remains proudly family-owned and operated. With a hands-on approach and deep ties to the Mudgee community, we are trusted by industries across agriculture, construction, and manufacturing.
