The Tujuh Bukit porphyry deposit is the largest and most exciting discovery in Indonesia, and perhaps the world, in recent times. A total of 1.8 billion tonnes inferred global resource of ore at an average grade of 0.46% of copper and 0.50 gram per tonne of gold containing 8.2 million tonnes of copper and 29 million ounces of gold.
In early 2018, work began on feasibility study activity for the underground development of the exploration decline and progressed encouragingly towards the development of a long life, low cost underground copper/gold mine. Given the exceptional drill results in 2021 and changes to the overall geological model, additional mining optimizations are required for the completion of the pre-feasibility study to support a higher Indicated Resource. The pre-feasibility study is expected to be announced in Q1 2023.
