Six foreign-controlled miners operating in Indonesia, including PT Vale Indonesia and a unit of Australias Newcrest Mining, intend to divest some of their shares to meet regulations.
According to Indonesian mining rules, foreign-controlled miners are required to gradually start reducing ownership after five years of production. Within 10 years, foreign ownership should be cut to at least 49 per cent.
The six companies included nickel miner Vale Indonesia and gold miner PT Nusa Hamahera Mineral, which is 75 per cent controlled by Newcrest Mining, Yunus Saefulhak, director of minerals, Energy and Mineral Resources ministry, said.
The others were gold mining companies PT Kasongan Bumi Kencana and PT Ensbury Kalteng Mining, as well as diamond miner PT Galuh Kencana, he added.
Saefulhak did not specify when the companies would start divesting their shares.
Chief Executive of Vale Indonesia Nico Kanter said last month that the company was in talks with the government on its divestment plan and expected to start before October this year.
Brazils Vale SA controls nearly 60per cent of Vale Indonesia, while public shareholders hold about 20 per cent of the companys stake.
Gold miner PT Natarang Mining, which is 85 per ent controlled by Australias Kingrose Mining, had also conveyed its divestment plan to the government, Saefulhak said.
