The success of Indonesian mining industry cannot be separated from the effort to improve mining policies which has attracted considerable number of foreign investment. Further improvement is required to accommodate future exploration and mining to be able to meet both national and investor interest. In the future, mineral exploration in Indonesia will be influenced by tighter space arrangement regulation. It is therefore recommended that people from mining industry could intensify exploration as well as mining development without damaging the environment. Besides that, they should be able to maintain important mineralized areas as mining areas.
