Operations The Company’s mines include: Pongkor - Gold Mine; Pomalaa - Nickel Mine and Ferronickel Smelters; Gebe - Nickel Mine for Export; Gee - Nickel Mine to Supply Smelters; Kijang - Bauxite Mine; Cilacap, Lumajang and Kutuarjo - Iron Sand Mines; Cikotok - Gold Mine run by Antam's subsidiary International Antam Resources Pongkor Gold Mine Pongkor mine is located near Bogor, in the province of West Java. The mine is approximately 90 km from Jakarta. The mine and its reserve areas are covered by KPDU893, which was granted in 1992 for a period of 30 years for gold and silver. The surface area is approximately 4,058 ha. Indications of gold deposits at Pongkor were discovered by Antam’s Geology Unit in 1981 and production commenced in May 1994. The Pongkor mine has three primary veins of gold, which are being mined; Ciguha Utama, Kubang Cicau and Ciurug. Pongkor Factory: A mechanised cut and fill method, with hydraulic jumbo drill and load haul dump (LHD), is proposed to be introduced by mid-1998 for the third vein, Ciurug. Ore from the stopes is processed in the processing plant which including crushing, milling, cyanidation, carbon in leach, carbon stripping, electro winning to melting and casting into anode moulds for refining, namely dore. The processing plant at Pongkor mine was originally designed with a capacity of 182,500 wmt per annum of ore, at grades of 15g/t for gold and 156g/t for silver, with recoveries of 96 per cent. and 79.5 per cent for gold and silver, respectively. Pongkor Gold Mine Gold production in the 2003 reached 1,033kg on higher ore grades at 12.53 gpt, Inline with higher gold production, silver production exceeded the target by 13%, reaching 7,048 kg. Antam is on track to produce between 4,100-4,500 kg of gold in 2003. Development activities continued on Ciurug, Pamoyanan and Gudang Handak, following the discovery of new gold deposits by Antam’s Geomin Unit in 2001. Drilling at Ciurug and Pamoyanan reached 898 metres and 14 metres, respectively. Pomalaa Nickel Mine Pomalaa is located 30 km south of Kolaka, in the District of Kolaka, which forms part of the Province of Southeast Sulawesi. It is on the eastern coast of the Gulf of Bone and has its own port for the loading and unloading of ore and ferronickel and for delivery of major consumables and large items. The port has a draft of 6m larger ships are loaded offshore from barges. At Pomalaa, the saprolitic material is considered to be ore. The limonitic material is pushed out of the way and used for backfill after extraction of ore is complete. The Pomalaa mine is divided into three areas, the northern the middle and the southern, covering an area of approximately 7,589 ha. The northern and the middle areas are covered by two mining rights (KPs/KWs), KPDU05 and KPDU53, respectively which valid until 16th July 2000, and the southern area by KPDU04 and KPDU52, respectively which valid until 15th March 2009. Ore from Pomalaa mine is sent to the Pomalaa ferronickel smelting plant and the remaining ore is exported, mainly to Japan. Gebe Island Nickel Mine Gebe Island is located in the Regency of Central Halmahera, in the Province of Moluccas. It is situated on the equator, about 40-km east of the easternmost point of Halmahera Island. Gebe Island is about 45 km long and 2 km to 6 km wide and the mine lies centrally on the south-western coast. Gebe Island has its own port for loading and unloading of nickel ore and for the delivery of major consumables and large items. The port has a draft of three metres, which allows barges to dock at the port. Larger ships are unloaded offshore from the barges. The Gebe Island mine and its reserves area are covered by KPDU286 which granted on 5th September 1981 for 30 years and covers an area of approximately 1,225 ha. The Gebe Island mine produces saprolitic and limonitic nickel ore. Saprolitic nickel ore primary export to Japan whilst minority sent to the Pomalaa ferronickel smelting plant. Limonitic nickel ore majority was exported to Australia. Gee During 2003, Antam produced 1,800 tonnes of contained nickel in ferronickel. Kijang Bauxite Mine The operations at Kijang on Bintan Island were assimilated within Antam in 1968. Kijang mine produces chemical grade bauxite for export. It is now reaching the end of its long life. The Company has a bauxite mine in Kijang, Bintan Island, province of Riau, covering an area of 8,002.4 ha. Discovery of bauxite was first reported in 1924 on Bintan Island, from which bauxite has been mined and exported sice 1935. Cikotak Cikotok Gold Mine run by Antam's subsidiary International Antam Resources Antam formerly sets for corporate restructuring on International Antam Resources Ltd. (IARL) and has performed a due diligence review on IARL for that purpose. Significant Events BHP Billiton Ltd. entered into a joint venture agreement with Aneka Tambang TBK PT (PT. Antam Tbk) to develop nickel laterite mines on Gag Island, off West Papua and North Maluku provinces. Aneka Tambang TBK PT has selected the consortium of PT Nava Bharat Indonesia dan PT Indika Energy Tbk as potential partner in the development of a Coal Fired Power Plant (CFPP) at Pomalaa. A consortium of Eramet SA from France and Mitsubishi Corporation from Japan would cooperate with Aneka Tambang TBK PT to build a nickel smelter in Halmahera, North Maluku in 2009. Antam and the consortium would mine nickel ore to be processed into nickel concentrate. History Perusahaan Perseroan (Persero) PT Aneka Tambang Tbk was founded in 1968.
