SnapshotThe Bumi Barito Mineral (BBM) Coking Coal Project is producing metallurgical low-volatility hard coking coal (LVHCC) and high-grade thermal coal.

BBM began its mining operations in September 2022, focusing on Pit 3. Commercial production of metallurgical coal commenced in November 2022, with the first commercial coal sales realized in 2024.

BBM uses selective mining to maintain quality without a Coal Preparation Plant, with a wash plant planned for further product enhancement.

In 2025, capital expenditure focused on critical infrastructure:
• Upgraded KM70 bridge and reinforced haul roads between Krajan Jetty and Pit 3;
• Strengthened bridges and culverts to ensure reliable, year-round logistics during the rainy season.

This infrastructure stabilization ensures a robust supply chain as the mine scales toward full capacity.

Licensing for underground mining at Pits 1 & 3 is progressing, with development slated for Q3 2026.

Summary:

The Bumi Barito Mineral (BBM) Permit Area is bisected by the Barito River which cuts through the tenement in a north-south trend. Almost the entire IUP contains coal-bearing sediments with open cut mineable areas controlled by the Barito River and three major fault systems. Coal analyses from more than 130 mapped outcrops on the west side of the Barito River (West Block) indicate it also contains premium quality anthracite and PCI coals. This coal does not currently form part of stated BBM coal Resources and provides potential for significant future expansion of BBM Resources.

Several high-quality metallurgical coal seams have been discovered in BBM, including seams B, C, D, and J. These seams are characterized by low-ash, low-sulfur, low-lead, and ultra-low-phosphorus coal with high vitriol content (over 90%). Seam J is particularly notable for its high swelling index, which is a success for coking.

Commodity Production

Mining operations at BBM were suspended in January 2025 due to multi-year low prices but recommenced in September 2025 under a scaled-down program targeting approximately 45,000 tonnes of near-exposed reserves (29,000 tonnes accessible without blasting and a further 16,000 tonnes requiring blasting from November 2025).

BBM commenced commercial production of metallurgical coal in November 2022 and realized its first commercial coal sales in 2024.
