Cokal Ltd. is set to resume mining operations at its Bumi Barito Mineral (BBM) coking coal project in Central Kalimantan, Indonesia, after securing RKAB approval.
The green light ensures near-term operational continuity, prompting the company to immediately launch operational readiness and reactivation activities.
Mining operations are on track to recommence by mid-June, following the completion of site preparation, equipment mobilisation, and pit dewatering.
The RKAB is Indonesia’s annual nickel ore mining quota system that determines the volume of ore that miners are allowed to extract each year.
Hauling operations have already resumed, allowing coal to be moved to stockpile locations. While river barging activities from the Krajan Jetty are temporarily paused pending improved river conditions, Cokal has successfully stockpiled sufficient cargo at the Batu Tuhup Jetty to finalise an export shipment of approximately 10,000 metric tonnes of low-volatile hard coking coal by the end of June.
The announcement follows an operational milestone on June 4, when Cokal successfully executed its first controlled blast at Pit 3.
Conducted by Sun Mining Services and mining contractor PT Harapan Mitra Lestari, the blast is expected to vastly improve fragmentation and overall mining productivity.
Logistical upgrades are also ramping up at the Batu Tuhup Jetty, where Rexline Engineering is set to install a 250 tonnes-per-hour roller crusher system alongside a bulk loading conveyor to enhance product size control and quality consistency.
Furthermore, contractor Petrosea is progressing earthworks on an all-weather haul road designed to support a three-million-tonnes-per-annum capacity.
Looking ahead, Cokal is navigating the regulatory framework for underground mining development, aiming to lock in environmental and forestry permits by the final quarter of 2026 ahead of early 2027 preparatory works.
Reflecting a tightening of production allocations by Indonesian authorities, Cokal plans to submit an RKAB revision at the end of June to better align approved volumes with its updated, long-term production requirements.
The company expects that continued regulatory clarity over time will support improved alignment between production planning, RKAB allocations, and commercialisation frameworks.
