Rio Disputes Mongolian Claim Over $130 Million of Unpaid Taxes

Mongolia’s Tax Authority claims a Rio Tinto Group unit operating in the country has unpaid taxes, penalties and disallowed entitlements associated with the $6.6 billion Oyu Tolgoi copper mine development.

Rio’s Turquoise Hill Resources Ltd. says it has paid all taxes and charges required under its accord with the government and has complied with the country’s laws, the Vancouver-based unit said yesterday in a statement. The disputed amount is about $130 million, Ganbold Davaadorj, a director of the mine’s operating unit Oyu Tolgoi LLC, said yesterday in an interview.
