Macmahon Expands Contract Role at Telfer Gold Mine

Macmahon Holdings Limited (ASX: MAH) revealed on 24 August 2026 that it will continue its mining services at Greatland Resources’ Telfer Gold Mine in Western Australia after its subsidiary, Macmahon Contractors Pty Ltd, entered into a new 42-month service extension agreement. The agreement, awarded by Greatland Resources Limited (ASX: GGP), carries a contract value of AU$485 million over a 42-month period. The extension strengthens Macmahon’s involvement at the Telfer Gold Mine, where the company has been providing mining services since 2015. The renewed agreement highlights the continuation of a long-term client relationship built through consistent operational delivery and mining expertise.

West Dome Stage 7 Supports Operational Expansion

Under the extended contract, Macmahon will support expanded mining activities at the West Dome Stage 7 area of the Telfer operation. The expanded scope covers higher mining volumes, alongside key services including drill and blast, loading and hauling, and other supporting operational activities. The contract extension aligns with Macmahon’s broader strategy of strengthening its mining services portfolio through long-term partnerships and integrated operational capabilities. Macmahon delivers a broad range of mining and infrastructure solutions, including surface mining, underground operations and civil construction services throughout Australia, New Zealand and Southeast Asia.

Strategic Contract Supports Growth Outlook

The Telfer extension adds to Macmahon’s secured work and continues a relationship at the site that began in 2015. The company said the expanded scope is expected to assist Greatland in progressing the next stage of Telfer’s growth and value generation. Macmahon’s Managing Director and CEO, Michael Finnegan, highlighted that the agreement represents an important milestone in the relationship with Greatland Resources and demonstrates the strategic importance of Telfer to the company’s operations. Macmahon continues to prioritise operational safety, dependable project execution and efficient service delivery while strengthening its long-term partnership with its client.

Diversified Mining Services Platform

Macmahon continues to operate as an ASX-listed mining and civil infrastructure services provider, offering expertise across surface mining, underground mining and infrastructure projects. Its diversified capabilities support resources, infrastructure and renewable energy sectors across multiple locations. Shortly after the Telfer award, MGX Resources announced on 31 August 2026 that the Central Tanami Project Joint Venture had signed a contract worth about AU$38 million with Macmahon Underground Pty Ltd for the Groundrush underground decline in the Northern Territory. With these contract wins and an FY26 order book of AU$5.9 billion, Macmahon strengthens its secured project pipeline while maintaining focus on operational excellence, client partnerships and sustainable growth across the mining services sector.
