Coal mining is the backbone of Indonesia’s energy industry, which in 2024 recorded a national production reaching 836 million tons 117% of the target.
Amid rising global energy demand and exports, open pit mining methods dominate operations at PT Golden Energy Mines Tbk (GEMS). With five strategic concession areas, GEMS is not only a producer but also a major player in maintaining energy security.
GEMS’ Strategic Mining Areas
GEMS manages coal mining concessions in Kalimantan and Sumatra through its subsidiaries that hold coal mining permits, namely PT Borneo Indobara (BIB), PT Barasentosa Lestari (BSL), PT Kuansing Inti Makmur (KIM) and its subsidiaries, PT Trisula Kencana Sakti (TKS), and PT Era Mitra Selaras (EMS) along with its subsidiaries.
By the end of 2024, the total mining area managed will reach approximately 66,204 hectares, with coal reserves of 900 million tons.
Strategically located in Kalimantan and Sumatra, GEMS is also superior in logistics, both for domestic market fulfilment and exports. This diversification strengthens the resilience of the supply chain in the coal mining industry in Indonesia.
3 Active GEMS Mines that Support Strategic Production
The coal mining industry in Indonesia is becoming increasingly dynamic over time. GEMS currently operates through three subsidiaries, namely:
- BIB (Borneo Indobara)
Located in Tanah Bumbu, South Kalimantan, BIB is the backbone of GEMS’ production. This open-pit coal mine produces medium-calorie coal for power plants and the Asian export market.
With digital monitoring and hauling integration technology, production efficiency is a key strength.
- BSL (Barasentosa Lestari)
Located in Musi Rawas, South Sumatra, this mine focuses on low-to-medium calorific coal production. As a major player in supplying DMO to PLN, BSL strengthens national energy security through domestic supply chains. Sustainable mining practices are implemented with a focus on efficiency and regional distribution.
- KIM (Kuansing Inti Makmur) and its Subsidiaries
Located in Bungo Regency, Jambi, KIM and its subsidiaries supply medium-calorie coal suitable for the domestic and limited regional markets. Although its contribution is smaller, KIM is an important node in local economic growth and GEMS’ expansion in the Sumatra region. Mining operations are also carried out with an adaptive approach and an emphasis on efficiency.
Efficiency and Sustainability: Part of the System, Not Just a Tagline
GEMS implements sustainable mining practices through concrete measures: post-mining land reclamation, wastewater treatment, solar panel utilization, and fuel efficiency.
This approach is not just a temporary response to global pressures, but has been the blueprint since the company began operations. It also reaffirms GEMS’ long-term commitment to balancing productivity with sustainability.
