2. Pongkor Gold Mine in Bogor

Pongkor is the largest epithermal gold mine in Indonesia, located in Bogor, West Java. As explained in the 2013 UGM Repository.

Citing ANTAM's website, ANTAM's primary gold and silver production comes from the Pongkor underground mine in West Java and Cibaliung, Banten.

Indications of gold deposits in Pongkor were discovered by the Geomin Unit in 1981, and production began in 1994 after obtaining a permit in 1992.

The Pongkor gold mine has three main gold veins: Ciguha, Kubang Cicau, and Ciurug.

The mining method uses conventional cut and fill stoping at the Ciguha and Kubang Cicau gold veins.

In 2021, ANTAM's total consolidated gold ore reserves were recorded at 1.02 million dry metric tons (dmt), equivalent to 203,000 troy oz (6.31 tons) of gold metal.

Meanwhile, ANTAM's consolidated gold mineral resources in 2021 were recorded at 6.75 million dmt, equivalent to 1,037,000 troy oz (32.25 tons) of gold metal.

After the gold ore is mined, it is processed through several processes, including crushing, milling, cyanidation, carbon leaching and stripping, electro-winning, and casting, to produce bullion/dores.

The dores/bullions produced from the mine are then sent to be refined into gold at the Precious Metals Mining Plant (UBPP Logam Mulia) in Jakarta.
