Macmahon Expands Underground Mining Operations in Western Australia

Highlights

• Macmahon secures two underground mining contracts in Western Australia

• Deflector contract set to contribute significantly to company’s orderbook

• New agreement with Genesis Minerals includes Gwalia and Ulysses projects

The underground mining services sector plays a critical role in the extraction of minerals such as gold and copper, supporting the broader resources industry across Australia. Companies operating in this sector typically provide services including mine development, production support, and associated infrastructure. Macmahon is a key player in this space, delivering mining and civil infrastructure services throughout Australia and Southeast Asia.

Macmahon Secures Deflector Project Contract

Macmahon (ASX:MAH) has obtained a contract to provide services at the Deflector Underground Gold-Copper Mine located in Western Australia. The agreement includes underground and mine development work, in addition to production services and other related activities. The contract is scheduled to commence in the coming weeks, strengthening Macmahon’s secured orderbook through a multi-faceted operational scope.

The Deflector project is a significant gold and copper producing site, and this new engagement is expected to contribute materially to Macmahon’s project pipeline. With this contract, the company continues to reinforce its position in underground operations, aligning with its history of executing complex mining activities across diverse geological settings.

Engagement with Genesis Minerals at Gwalia and Ulysses

Macmahon has also been appointed as the underground mining contractor for Genesis Minerals’ (ASX:GMD) Gwalia and Ulysses projects, both situated in the Lenora region of Western Australia. These projects are set to benefit from Macmahon’s broad range of services including underground development, mine production, and comprehensive support works.

Under the terms of the new agreement, Macmahon will undertake operations at both sites for a defined period, following the mutual termination of the previous Gwalia-only contract. The consolidated contract represents a strategic alignment between the two companies, enabling Macmahon to extend its involvement across multiple sites under a unified structure.

This development is expected to enhance Macmahon’s operational scale in the region while streamlining service delivery across the two projects. Work on the new arrangement is set to commence immediately, integrating both projects under a single execution framework.

Growth of Secured Orderbook and Market Standing

Macmahon’s latest contract wins will substantially increase its secured orderbook, reflecting the company’s consistent acquisition of large-scale mining service projects. With a solid foundation in both surface and underground mining, the company continues to attract significant engagements from mid-tier and major resource operators.

Macmahon’s market capitalisation reflects its presence in the sector, and its ongoing project wins suggest strong demand for its services in complex underground environments. The combination of operational capability and regional familiarity supports its ongoing participation in high-grade mining regions such as Western Australia.

Company Profile in Mining Services

Macmahon provides comprehensive mining services across Australia and Southeast Asia, covering both surface and underground mining, as well as civil infrastructure. The company has developed a reputation for delivering integrated project solutions across the lifecycle of mine operations, from early-stage development through to full production and site rehabilitation.

With experience in managing diverse mining conditions, Macmahon is positioned as a key contractor in both emerging and established mining hubs. The recent additions to its secured orderbook reinforce its operational footprint and underline its continued activity in resource-rich areas.
