Indonesia says a comprehensive audit of the operation of PT Freeport Indonesia, which was initially expected to be completed last month, is not finished yet.
Indonesia's Energy and Mineral Resources Minister made the annoucement following a meeting with the audit team.
He says the five subjects of the audit are environmental impact, security, community development, production and revenue.
The ministry's technical environmental director, who chairs the audit team, says he hopes the final result will come out in two weeks.
The ongoing audit was partly sparked by violent protests back in March, requesting the closure of Freeport's gold mine operation in Papua.
At least six people were killed in the protests.
The company has been accused of not giving enough to the people of Papua in return for the mine, and of polluting and being responsible for human rights abuses through their use of the military for protection.
