Thiess has secured a 14-month extension to its contract at the Wahana coal mine in Satui, Indonesia – continuing a long-standing partnership with PT Wahana Baratama Mining.
The extension will see Thiess carry on with overburden removal and mining activities, drawing on its established site infrastructure and technical capability. The company also reaffirmed its commitment to maintaining high safety and environmental standards throughout operations.
Thiess group executive chair and chief executive Michael Wright said the extension highlighted the strength of the company’s partnership with Bayan Resources.
“This extension reinforces our strong relationship with Bayan and reflects the trust they place in our team to deliver safe, sustainable and efficient mining solutions. It is a testament to our people on the ground whose dedication and performance continue to create long-term value for our clients,” he said.
Awarded by long-term client PT Wahana Baratama Mining, the contract reflects Thiess’ strong performance on site and its collaborative approach to project delivery. The extension is expected to support the client’s access to additional coal reserves, unlocking higher production capacity through 2025 and 2026.
Thiess group executive – Asia, Cluny Randell, said the extension underscores the company’s operational agility.
“We’re proud to continue supporting Wahana. This extension highlights the benefit of having a scalable and responsive operation, underpinned by our deep understanding of the site and our commitment to operational excellence,” Randell said.
Thiess has operated at the Wahana site for more than a decade, building a strong reputation as a reliable partner in Indonesia’s mining industry. The business provides services in open-cut and underground mining across Australia, Asia and the Americas.
Now in its 90th year, Thiess continues to embrace change and contribute to the global energy transition through mining practices that support both productivity and sustainability.
