Additionally, coal and rock sampling produced 1,707 coal samples for quality analysis, 299 core samples for rock acidity testing, and 565 samples for rock mechanics testing.
Other activities included monitoring the ToCBoC Front of the mine at various locations, such as Muara Tiga Besar, Air Laya, Banko Barat, Banko Tengah A, and Banko Tengah B.
Additional costs were allocated for database management, software licenses, and other operational activities.
In another area, PTBA’s subsidiary also explored PT Internasional Prima Coal’s (IPC) mine. The exploration was carried out by PT Prasetya Abdi Perkasa using coring and open hole methods.
