Macmahon Holdings Limited says it has been awarded a two-year contract extension by Vault Minerals (formerly Red 5) at the Daisy Milano gold mine within its Mount Monger operation in the Kalgoorlie region of Western Australia.

Macmahon has been providing underground mining services at Daisy Milano since acquiring the contract earlier this year as part of the takeover of the Pit n Portal (PnP) underground services business from Emeco Holdings Ltd, including mine development, production charging and load and haul services.

The two-year contract extension to October 2026 is expected to add approximately A$90 million ($58 million) of revenue towards Macmahon’s secured orderbook and will utilise
existing fleet as required for the project.

Macmahon CEO and Managing Director, Michael Finnegan, said: “We are delighted to continue working with the team at Daisy Milano and building on our valued relationship with Vault Minerals. We are focused on continuing to drive safety and performance outcomes for our client.”

In the 2024 financial year, the Mount Monger operations delivered total gold sales of approximately 97,000 oz at an all-in-sustaining-cost (AISC) of A$2,176/oz. The three mining centres – Daisy, Mount Belches and Aldiss – produced approximately 657,000 t of ore at an average grade of 3.9 g/t Au from underground sources and approximately 67,000 t of ore at an average grade of 0.93 g/t Au from open-pit sources.
