Open-pit gold mine. Started in 2007.

The Bonikro deposit is hosted primarily within a small granodiroite intrusion. Mineralisation extends into surrounding basalts to the south, and is controlled along a moderately dipping shear zone. Gold occurs associated with quartz and pyrite, with the highest gold grades occurring around the intersection of the shear and the granodiorite. Overall, the deposit has an average grade below 2g/t gold.

Owned by Newcrest Mining (formerly owned by Lihir Gold who merged with Newcrest Mining).

The nearest regional town is Hiré, about 9 kilometres from the mine.
