PT Bukit Makmur Mandiri Utama (BUMA), BUMA International Group’s key subsidiary, has secured a long-term contract with PT Adaro Indonesia for operations at the South Tutupan Mine in South Kalimantan, Indonesia.
The agreement is set to commence on 1 April 2026 and will continue until 31 December 2030.
The contract outlines that BUMA will manage the removal of approximately 239 million bank cubic metres of overburden and the extraction of 44 million tonnes (mt) of coal, equating to average annual volumes of 50.5 million bank cubic metres and 9.3mt of coal, respectively.
It further strengthens the two companies’ partnership, which has been in place for more than two decades, and enhances BUMA’s revenue stability and long-term earnings.
BUMA president director Ronald Sutardja: “We are pleased to announce this significant contract with Adaro Indonesia, one of our valued long-term partners.
“The contract is a testament to BUMA’s consistent operational delivery and our ability to manage technically complex mining operations safely and reliably. It strengthens our contracted earnings visibility and reinforces our position as Indonesia’s trusted mining services partner.”
BUMA International Group, established in 1990, operates in Indonesia, Australia and the US. It focuses on four main areas: mining services, mine ownership, social enterprise and technology.
The group expanded its operations into mine ownership in 2024 by acquiring Atlantic Carbon Group. In the same year, it also ventured into future-facing commodities with the acquisition of a stake in Australian company 29Metals, which specialises in copper and base metals.
BUMA was established in 1998 and provides mining services to coal producers in Indonesia.
