Antam reports Q4 gold, nickel exploration activities

The following is an excerpt from IDX-listed mining firm PT Aneka Tambang (Antam) on gold, nickel, bauxite and coal projects taken from the quarterly report ended December 31, 2010.

EXPLORATION*

In 4Q10, Antam continued its exploration on nickel, gold and bauxite In Indonesia. Total preliminary costs reported by Geomin Unit for exploration on above commodities reached Rp40.4 billion.

Nickel
Antam conducted nickel exploration activities at Bull in Halmahera, Mandiodo and Lasolo in Southeast Sulawesi.

Antam conducted nickel exploration activities at Bull including Sangaji area with 100 m, 50 m and 25 m drilling distance, modeling, test pitting, topography and grid measurement, and also sampling.

Nickel exploration activities at Mandiodo and Lasolo focused on improving resources classification. The activities included 200 m, 100 m and 25 m drilling distance, core sampling, mapping, grid and drilling pit measurement, polygon measurement, SG and MC measurement.

Total cost for nickel exploration amounted to Rp9.1 billion.

Gold
Antam conducted gold exploration activities at Dairi and Karo in North Sumatera, Muara Manderas in Jambi, Pongkor, Papadayan and Cibaliung in West Java, Wawonli and Koloni in Soustheast Sulawesi, Mao in West Sulawesi and Oksibil in Papua.

Exploration activities at Dairi included Semi Detailed Geological Mapping (SDGM), Detailed Geological Mapping (DGM), opening, and took samples of rock, soil and Fi/petmin/XRD.

Antam conducted exploration activities at Muara Manderas including drilling activities, DGM, opening and collected rock, core, Fi, petro/mineragraphy and XRD samples.

Exploration activities at Pongkor focused on cqre drilling activities, track measurement, magnetic geophysics, CSAMT geophysics, DGM, detailed mapping structure, collected samples of core, Fi, rock, soil, petrography, mineragraphy and XRD. Exploration activities at Papandayan included SDGM, DGM, opening, drilling, outcrop measurement, CSAMT measurement, magnetic geophysics, CSAMT geophysics and collected samples of core, rock, FI, pet/mm and XRD. At Cibaliung, Antam conducted DGM, collected Fi samples, XRD samples, pet/mm samples and core samp?es and also conducted drilling.

Exploration activities at Wawonii and Koloni included SDGM, DGM, opening and collected rock and Fi/XRD samples

Activities at Mao, Batuisi and Karosa included SDGM, DGM, opening, sampling of rock, SS, soil, pet/mm and magnetic geophysics.

Exploration activities at Oksibil included SDGM, DGM, opening, collected rock, 55, soil pet/mm samples and conducted magnetic geophysics.

The total cost for gold exploration reached Rp25.3 billion.

Bauxite
Antam conducted bauxite exploration activities at Mempawah, Landak, Tayan and Munggu Pasir, of West Kalimantan.

In general, exploration activities at West Kalimantan included grid measurement, test pitting and sampling to support efforts in increasing classification of both resources and reserves estimations.

Total cost of bauxite exploration including other industry minerals reached Rp6 billion.

*Preliminary result, Antam also releases monthly exploration report.
