PT Bumi Resources Tbk is an Indonesia-based coal mining company primarily engaged in the exploration, extraction, processing and marketing of thermal coal. Established in the early 1980s as part of the Bakrie Group conglomerate, Bumi Resources has grown into one of the country’s leading coal producers by leveraging a network of subsidiaries and joint ventures to secure and develop large-scale reserves. The company’s core business activities encompass open-pit mining operations, coal handling and transport logistics, as well as coal trading both domestically and in export markets.
Through its key operating units—among them PT Kaltim Prima Coal and PT Arutmin Indonesia—Bumi Resources maintains mining concessions predominantly on the islands of Kalimantan and Sumatra. These assets benefit from well-developed port facilities and integrated rail systems, enabling efficient movement of bulk thermal coal to major industrial and power generation customers. The company’s product slate consists of low-to-medium rank thermal coal grades, which it sells under both long-term offtake agreements and on the spot market across Asia, including to utilities and steel manufacturers in China, India and Southeast Asia.
Over its history, Bumi Resources has invested in modern mining technology and environmental management practices designed to enhance operational safety and reduce its ecological footprint. It has incrementally expanded its resource base through strategic acquisitions and exploration programs, and has periodically upgraded its port and stockyard infrastructure to support higher export volumes. While the company remains focused on coal, it has also explored diversification opportunities in related mining services, logistics and coal-to-energy projects that align with Indonesia’s evolving energy landscape.
The company is overseen by a board of commissioners chaired by Aburizal Bakrie and supported by a management team headed by President Director Fabio Tumiwa. This leadership duo brings a combination of deep sector experience and strategic vision aimed at securing long-term growth. Bumi Resources continues to emphasize disciplined cost management, community engagement in its host regions and adherence to stringent safety and environmental standards as it seeks to maintain its position in the global thermal coal market.
