Mongolia, Rio and Ivanhoe agree on stake deal

Resource-rich Mongolia has attracted many foreign investors

Mongolia and mining giant Rio Tinto and Ivanhoe have reached an agreement on stakeholding of the Oyu Tolgoi project in the resource-rich country.

The Mongolian government had sought to increase its stake in the mine to 50% from 34% as previously agreed.

The mining companies had said that the government should honour an original agreement signed in 2009.

When completed, the project is expected to be one of the biggest copper mines in the world.

According to the initial agreement, Mongolia government could renegotiate its stake after a period of 30 years.

However, the authorities had wanted to bring forward the negotiation period, a move that did not go down well with the miners as well as industry analysts.

In a joint statement released on Wednesday, they said "all parties have reaffirmed their continued support for the investment agreement and its implementation".

Shares of Ivanhoe rose as much as 18% on the Toronto Stock Exchange.
