Through our subsidiaries, Batubara Development Pte. Ltd. and PT Deli Niaga Sejahtera, we hold interests in five coal mines in Central Kalimantan, namely PT Persada Kapuas Prima, PT Persona Bara Cakrawala, PT Cakrawala Bara Persada and PT Pasir Bara Prima and PT Tri Oetama Persada (TRIOP). Collectively, these five mines have a total estimated proved and probable coal reserves of 226 million tonnes, with GAR (Gross As Received) of approximately 4,000 kcal/kg to 5,000 kcal/kg.

By diversifying into coal mining, we have added a synergistic income pillar and created a vertically-integrated business model, allowing the Group to capture margins across the entire coal supply chain, from mining and sales to direct delivery to customers.
