In my opinion it is unlikely any new companies will come to mine in Indonesia. If the current regulations remain in place, any new company will face a significant cost penalty due to the requirement to build processing facilities in the country. This is likely to make Indonesia economically unattractive compared to other countries, although strategies such as shared processing facilities could alleviate this.
There are indications this year however that the Indonesian government may relax those regulations in 2017 due to pressure from mining companies, and the significant loss of revenues since the regulations were implemented in 2014 (Jamasmie, 2016). If this happens Indonesia may again become attractive for new operators.
Whether these changes happen or not however, the fact remains that the Indonesian government’s regulatory volatility poses a significant risk to mining operations for any new operator. Any prospective prospector must account for the additional financial risks associated with such a temperamental regulatory system. In other words, they should not be relying solely on Indonesia for profit, but instead have diversified income streams to manage this risk.
