Liputan6.com, Jakarta - PT Bukit Asam Tbk (PTBA), one of Indonesia’s coal producers, has demonstrated a strong commitment to ensuring the sustainability of the nation’s energy supply. In the first quarter of 2026, the company allocated funds for exploration activities focused on the Tanjung Enim mining area in South Sumatra.

To achieve this objective, PTBA has incurred expenses of Rp 25.80 billion (unaudited) in the first quarter of 2026. These activities involve PTBA’s internal team as well as drilling contractors, demonstrating a comprehensive approach to exploration efforts. The primary focus of this exploration is the Tanjung Enim Mining Site (TEMS).

Exploration activities conducted by PTBA at the Tanjung Enim Mining Site (TEMS) in the first quarter of 2026 included drilling, geophysical logging, coal and rock sampling, and monitoring of the ToC-BoC at the mine front. This information was cited from an IDX disclosure on Wednesday, April 8, 2026.

Drilling operations were conducted at four mining permits—namely the Air Laya, MTB, Banko Barat, and Banko Tengah B permits—at 94 locations, reaching a total depth of 14,652 meters. The primary objective of the drilling activities in the first quarter was to expand the exploration coverage area in TEMS.

PTBA revealed that other exploration activities were conducted across five of its IUPs (Mining Business Licenses) in TEMS. These activities included coal and rock sampling at exploration drill points, as well as coal sampling from active pits for quality control (QC) purposes. The progress recorded includes 1,202 coal samples (from drill cores and mine fronts), 302 rock core samples for rock acidity testing, and 693 rock core samples for rock mechanics testing. Additionally, TOC (Top of Coal) and BOC (Bottom of Coal) measurement monitoring was completed over an area of 602 hectares.

Activity Details

In the areas of Air Laya, Muara Tiga Besar, West Banko, and Central Banko B, the company allocated Rp 18.08 billion for exploration activities. These activities were carried out by an internal team in collaboration with PT Resources ID, utilizing coring, open-hole, and geophysical logging methods.

As a result, the company successfully completed 94 drill points with a total depth of 14,652 meters through infill drilling. Additionally, there were 90 further drill points with a total drilling length of 12,982 meters.
