SnapshotThe Tujuh Bukit Gold Mine is one of Indonesia’s foremost primary gold mines. In addition to gold, the mine also produces silver.

Merdeka continues to optimize mining operations to extend the mine’s economic life through 2030. Exploration in 2024 identified new mineralized zones with the potential to increase gold reserves.

During Q1 2025, Merdeka initiated a transition to a larger-capacity load and haul fleet to reduce mining unit costs.

As of Q1 2025, key infrastructure projects are progressing in line with the plan:
• Construction of Heap Leach Pad A, Stage 5, and the Pad A Extension is well underway.
• Design and feasibility studies for additional heap leach pad expansions to support increased stacking rates are expected to be completed by 3Q 2025.
