A US-based mining giant has warned it could take legal action against Indonesia over a dispute about the Grasberg mine in Papua province.
Freeport-McMoRan said it could take Indonesia's government to arbitration and seek damages over the contractual dispute which has stalled operations at the world's second-biggest copper mine.
Freeport is in protracted negotiations with Jakarta over the terms around extension of its licence to mine the massive Papua deposit.
The mining conglomerate was already in dispute over US$469 million in water taxes and penalties claimed by Papua province dating back to 2011.
But mining operations at Grasberg ground to a halt eleven days ago over a government move to halt exports of copper concentrate to boost domestic industries.
Freeport said it would only agree to a new mining permit with the same fiscal and legal protection in its current contract.
