All paperwork is complete for the Indonesian government to sign a final agreement to acquire a majority stake in the Grasberg copper mine in Papua province, a source familiar with the matter told The Straits Times. Previously in July, Reuters reported that Freeport-McMoRan Inc agreed to sell a majority stake in the world’s second-biggest copper mine to the Indonesian government via a series of complex deals worth $3.85 billion, potentially ending a long-running dispute on mining rights. Indonesia and Freeport have been locked in negotiations for more than a year over the miner’s long-term presence in the country. Talks have been peppered by reports of progress, usually from the Indonesian side, followed by complications, according to Bloomberg.
