Negotiations to Set Oyu Tolgoi Loan Interest Rates in Line with International Market Standards

On the first day of negotiations between the Mongolian Government’s Working Group — established by order of the Prime Minister — and Rio Tinto Group’s authorized delegation, the two sides reached agreement on several key issues and signed a protocol.

The protocol officially confirms the start of discussions to review the appropriateness of the shareholder loan interest rates under the Oyu Tolgoi project. Both sides aim to reach a decision by January 31, 2026. If no agreement is reached within this timeframe, they have agreed to extend the negotiation period.

The parties have agreed to determine the shareholder loan interest rates in accordance with international market standards and to discuss other terms related to loan interest conditions.

Additionally, with regard to management service fees, the sides agreed to work toward a fair, internationally comparable, and mutually acceptable solution, and to maintain the current composition of the working groups throughout the negotiation process.

Negotiations are ongoing.
