Macmahon Holdings renews ties with Vault Minerals at Daisy Milano gold mine

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.

Westfill secures underground mining contract at Vault Minerals’ Rothsay mine

Westfill Pty Ltd is pleased to announce the award of a two-year underground mining contract with Vault Minerals, previously Silverlake Resources, for the Rothsay mine, in the southern Murchison region of Western Australia.

The contract encompasses both development and production activities, focusing on extracting mineralised ore from narrow sub-vertical structures. Operations at Rothsay commenced on September 17, and the award of the contract is testament to the solid relationship between Westfill and Vault Minerals, Westfill says.

Westfill Managing Director, Ashley Morcombe, said: “We are very excited to take on our first full principal mining services contract with Red5 (now Vault Minerals after the merger with Silverlake Resources) who are a valued client of Westfill’s.

“Our Darlot development team’s hard work and consistently high performance are what put Westfill up as a key contender for the Rothsay contract. I would like to thank our entire team for pulling the contract together and mobilising in a short time frame. We look forward to continuing our high performance and success at another of Vault Minerals’ sites.”

The Rothsay underground mine is a high‑grade satellite ore source, with ore road‑hauled approximately 197 km to the Deflector processing facility. In the 2024 financial year, the Rothsay underground mine produced approximately 221,000 t of ore at an average grade of 4.8 g/t Au.
