Resources, the Indonesian unit of London-listed Bumi, said it would act as quickly as possible to resolve the alleged financial irregularities it was accused of earlier this week.
Bumi Resources, which is 29 per cent owned by Bumi, said it received no advance notice of the investigation before the statement was released.
The Indonesian-based company said it would comply with all its obligations under Indonesian law.
“The management of PT Bumi Resources will be acting to resolve these matters as expeditiously as possible, for benefit of all stakeholders, and will make further announcements as appropriate in due course,” it said in a statement.
Shares in miner Bumi, founded by financier Nat Rothschild, were down almost five per cent in early trading.
