Oyu Tolgoi receives audit report from Mongolian Tax Authority Turquoise Hill (TRQ) announced that Oyu Tolgoi has received an audit report from the Mongolian Tax Authority claiming unpaid taxes, penalties and disallowed entitlements associated with the initial development of the Oyu Tolgoi mine. Turquoise Hill is of the firm view that Oyu Tolgoi has paid all taxes and charges as required under the Investment Agreement and Mongolian law. Turquoise Hill and Rio Tinto (RIO) are reviewing the detailed tax claim. Any element of the claim that amounts to a breach of the investment agreement will trigger the dispute resolution process outlined in the investment agreement including possible international arbitration. The impact of these claims on resolution of the outstanding shareholder issues is unclear at this time. However, completion of the underground feasibility study is likely to be delayed if a resolution to the tax matters is not reached before June 30. Turquoise Hill CEO Kay Priestly said, "We strongly disagree with the claims in the audit report and are currently reviewing all options to resolve this matter."
