TRANSFORM FOR A BETTER FUTURE
AMNT assumed control of the Batu Hijau mine in 2016. A post-acquisition review of operations, during which every aspect was examined from a new perspective, determined that the efficiency of most production processes could be enhanced, and downtime minimized. Implementing these recommendations resulted in a significant reduction in operational costs.
AMMAN also optimized the human resources base through providing extensive training and capacity development programs for staff and management. The company fosters a corporate culture that rewards “brave thinking”, in which employees at all levels can propose initiatives to create added value. Under AMMAN control Batu Hijau has broken historical records of productivity and efficiency. The revitalized Batu Hijau mine is now advancing into the next phase, extending the projected life by a decade or more.
AND THE FUTURE
When AMMAN acquired Batu Hijau in 2016, the mine was in Phase 6 of the comprehensive mining plan. In 2017, AMMAN began Phase 7, accelerating ore production by three years and processing the stockpile of oxidized low-grade ore. In April 2020, AMMAN began processing the first batch of fresh ore from Phase 7.
Drilling and resource modeling conducted during 2019 indicated promising results for the next phase of production. The continuous increase in efficiency and upward trend in commodity prices encouraged AMMAN to embark on Phase 8, extending the life of the Batu Hijau mine to at least 2030.
AMMAN plans to expand capacity of the ore-processing plant to handle the output of Phase 8 of Batu Hijau as well as projected output from the Elang project now being surveyed and assessed. Copper smelting and precious metal refining facilities currently under construction will support the Indonesian government’s initiatives to add value to exported natural resources.
