The topography measurements performed in Tanjung Buli were intended to connect the topographies of Tanjung Buli and Sangaji. Drill holes were also obtained through grid measurement on the two regions. In addition, drillings at 200x200 m and 100x100 m spacing were executed in Sangaji. In Sangaji and Tanjung Buli, drillings with 25x25 m spacing were also conducted . Furthermore, the exploration activities in the Tanjung Buli region included core logging and sampling, test-pitting, and XRD samling.
The exploration activities performed in Lasolo, Lalindu, and Tapunopaka consisted of topography and grid measurements, drillings, core logging, and samplings.

Antam's FY11 unaudited goldexploration cost was Rp110.5 billion.
Gold explorations in Batang Asai were comprised of detailed geological mapping, trenching, rock and XRD samplings, structure depiction, trenching, and drill holes. Gold activities in Pongkor included detailed geological mappings, core drillings, geophysics track measurements, and samplings. In Papandayan, gold exploration activities were comprised of semi-detailed geological mapping, detailed geological mappings, trenching, geophysics, and samplings.
BAUXITE
Antam's exploration activities with a focus on bauxite were performed in Mempawah, Landak Regency, West Kalimantan Province; and Tayan and Munggu Pasir, Sanggau Regency, West Kalimantan Province. The FY11 total unaudited cost attributable to bauxite explorations amounted to Rp16.1 billion. Grid measurement, pitting test, and sampling were performed on these regions.
