JAKARTA, June 30 (Reuters) - Indonesia’s state-owned mining holding company, PT Inalum, is close to finalising a multi-billion-dollar deal to acquire Rio Tinto's participating interest in the giant Grasberg copper mine, operated by Freeport McMoRan Inc, a government official said.
"Now we are preparing contracts. You could say it's already completed - all that's left is the finalisation of documents that need to be signed," Deputy State-Owned Enterprises Minister Fajar Harry Sampurno told reporters.
Sampurno added that the acquisition valued at "below $4 billion" would be announced by the government "in the near future" and may be completed in July. (Reporting by Cindy Silviana Writing by Fergus Jensen)
