Bakan
(North Sulawesi, Indonesia)
Bakan achieved initial production in Dec-13 having been built in just 24 months under extreme wet weather conditions that challanged both the construction and development teams. The mine uses a dynamic heap leach approach that is very suitable for such high sulphidation, epithermal, low-grade oxide ores and is a low cash cost producer.
There is great potential to expand reserves in CY16 at Main Ridge, Campsite, Vila & North Osela. Exploration targets exist at Busa, Gunung Botak and Jalina, all within trucking distance to the central process plant. Generative work is also reviewing a number of other significant prospects within the Bakan Block including the South Gosan, Tobayagan, Marpaung and others (Gloria, Pusian & Lantungan).
First Year of Operation : 2013 (December)
Production Capacity : 4,000,000 tonnes per annum
Processing Methodology : Heap Leach (dynamic)
Reserves & Grade @ 31-Dec-17 : 524 Koz @ 0.73 g/t Au
Resources & Grade @ 31-Dec-17 : 1,355 Koz @ 0.54 g/t Au

Doup
(North Sulawesi, Indonesia)
Doup is considered a carbonate (or calcareous shale) hosted strata-
bound epithermal replacement deposit. Its geological setting is a challange.Existing gold resources of 3,04 Koz at 1.20 g/t and reserves of 1,80 Koz at 1.26 g/t as of June 2017.
The complex metallurgical system hosts a weak Au-Cu porphyry signature with an ISE (Au-Ag-Te) overprint at Panang while Benteng mineralization is more Au-Ag-Te with As-Zn in a carbonate setting. Potential to add resources occur at North Benteng, the Link Zone and SE Panang while satellites exist at South Benteng and Tungow. Generative work on district targets is ongoing and there is much discussion about a porphyry core.
