Thiess secures two-year mining services agreement with Yilgarn Iron

We have entered an agreement with Yilgarn Iron to support the revival of iron ore production in the Koolyanobbing district in Western Australia, 400km east of the state’s capital city Perth.

The two-year mining services agreement, executed following a Letter of Intent signed in September 2025, will run until March 2028 with scope for expansion as Yilgarn Iron grows its production portfolio.

Thiess Group Executive Chair and CEO Michael Wright celebrated the partnership: “We are delighted to partner with Yilgarn Iron and contribute to a new phase for the Koolyanobbing iron ore mine, a cornerstone of Australia’s mining history. Through our sustainable mining approach, we will support Yilgarn Iron to deliver safe, efficient operations and achieve its production goals.”

Thiess Group Executive Australia West David Greig said: “This project will make a meaningful contribution to the social and economic fabric of the community, creating jobs and supporting sustainable development across regional Western Australia. Together, we are driving sustainable growth that will empower the region’s communities and industries for years to come.”

With its extensive experience and trusted expertise, we are committed to helping Yilgarn Iron achieve its operational targets, establish safe and reliable production processes, and foster long-term operational success.

The recommencement of operations in the Yilgarn Hub represents a new chapter for the Koolyanobbing district, a region with iron ore production roots stretching back to the 1950s.

Under the leadership of Yilgarn Iron, the targeted export capacity of more than 4 million tonnes per annum will contribute significantly to local employment across the Yilgarn andEsperance regions, strengthen the regional economy, and enhance long-term supply chain stability.
