Antam conducted nickel exploration at Buli-Halmahera at the Sangaji, Pakal, Tanjung Buli, Block A and P4P5 prospects. Antam began to drill with 50 m spacing drilling at these areas from previously conducting 100 m spacing drilling. Antam also conducted topography mapping at the South Sangaji area.
Exploration activities at Obi-Halmahera included 50 m spacing drilling at the Kawasi prospect and 25 m spacing drilling at Malamala prospect, which was followed with topography mapping.
In the Central Sulawesi region, Antam focused nickel exploration activities at the Tangofa and Buleleng prospects. Antam conducted 50 m and 25 m spacing drilling at both areas, followed with topography mapping.
Nickel exploration activities at Tapunopaka-Southeast Suiawesi induded core logging, sampling, 25 m spacing drilling, track measurement, preparation and analysis. Nickel activities at Southeast Sulawesi also covered the Baunaga, Pandua and Lalindu districts. At these areas, Antam conduced core sampling, track measurement and drilling, topography measurement, 100 m and 200 m spacing drilling and sample preparation.
Total nickel exploration cost reached Rp 11.6 billion.
