Global miner Rio Tinto
(ASX:RIO) says it will meet the June commissioning deadline on its Oyu Tolgoi project.
The news follows ongoing resistance from the Mongolian government.
The copper and gold project has already cost Rio $US6 billion, almost the entire forecast spend.
Cost blowout speculation has long plagued the venture.
The Mongolian government has made no secret of its concern that Rio will stop funding the project, leaving it with a revenue black hole.
Rio last reported a 47 per cent plunge in half-year underlying profit.
