       Gold has the highest malleability and ductility of any element. It is unaffected by air, water, all acids except aqua regia, and alkalis. It is a good conductor of heat and electricity. It is also a good reflector of infra-red radiation, and as it is inert makes an excellent coating for space satellites.

Bahan Baku

Gold is a chemical element with the symbol Au and atomic number 79. It is a dense, soft, malleable, and ductile metal with a bright yellow color and luster that is considered attractive, which is maintained without tarnishing in air or water. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements, solid under standard conditions. The metal therefore occurs often in free elemental (native) form, as nuggets or grains in rocks, in veins and in alluvial deposits. Less commonly, it occurs in minerals as gold compounds, usually with tellurium.

    ANTAM's main gold and silver production is sourced from its underground gold mines at Pongkor, West Java and Cibaliung, Banten. Indications of gold deposits at Pongkor were discovered by ANTAM's Geology Unit in 1981, and production commenced in May 1994 after ANTAM secured the mining license in 1992. The Cibaliung gold mine was acquired in 2009 from an Australian company, Arc Exploration and began to operate in 2010. The Cibaliung mine is operated by ANTAM's subsidiary, PT Cibaliung Sumberdaya. ANTAM also owns 25% of PT Nusa Halmahera Minerals which operates the Gosong mine in North Maluku. At the beginning of June 2013 ANTAM received an extension of forest borrow and use license for Pongkor gold mine until 2021.
