PT Vale Indonesia (INCO) spent USD 1.67 million—equivalent to around IDR 28 billion (assuming an exchange rate of IDR 16,800 per USD)—on exploration in the fourth quarter of 2025.
Exploration focused on areas within the company’s Special Mining Business Permit (IUPK), including the Sorowako Block and Sorowako Outer Area in East Luwu Regency.
It also covered South Sulawesi and the Bahodopi Block in Morowali Regency, Central Sulawesi, as well as the Pomalaa Block in Kolaka Regency, Southeast Sulawesi.
In a disclosure on Thursday (January 8, 2025), Vale reported spending USD 657.89 thousand in October, USD 508.77 thousand in November, and USD 507.08 thousand in December.
INCO carried out the exploration together with third parties, namely drilling and geophysics contractors.
The work used HQ-3 core drilling with 100-meter and 50-meter spacing to upgrade resource classification in Block 1 Tetenggala and Block 1 Lalombundi (Pomalaa Block).
Meanwhile, geophysical surveys employed the Electrical Resistivity Tomography (ERT) method, with measurements conducted in Block 1 Tetenggala (Pomalaa Block).
Management stated that test results are being processed for resource and reserve estimation using the ordinary kriging method in Sorowako.
At the Pomalaa Block, drilling with 100-meter and 50-meter spacing will continue in Block 1 Lalombundi and Block 1 Tetenggala (Pomalaa Block).
“Geophysical measurements using the ERT method will continue in Block 1 Tetenggala (Pomalaa Block). All drilling activities are planned to obtain a complete laterite profile,” management said.
