Turquoise Hill Resources Ltd. said March 13 that its 66%-owned Oyu Tolgoi LLC subsidiary received a request from the Mongolian Anti-Corruption Authority to disclose certain financial information.
Oyu Tolgoi operates the Oyu Tolgoi copper-gold-silver mine in the country.
Turquoise Hill, which is majority-owned by Rio Tinto, said there is no indication in the request that the Oyu Tolgoi unit is a subject of the investigation, which is related to a potential abuse of power by certain officials during the negotiations of a 2009 investment agreement.
In January, Oyu Tolgoi received a tax assessment of approximately US$155 million from the Mongolian Tax Authority.
In late February, Turquoise Hill outlined plans to lift a force majeure over copper concentrate supplies from the Oyu Tolgoi mine, after a protest in January obstructed a main access road.
