Deposit Type

  • Orogenic

Summary:

The Bonikro Gold Mine project area comprises the Bonikro and Hiré intrusion-related, shear-hosted orogenic gold deposits. The Bonikro gold mine is located in the Oumé Project area in central to southern Côte d’Ivoire approximately 230km northwest of Abidjan.

Mining Methods

  • Truck & Shovel / Loader

Summary:

Bonikro is a conventional truck and excavator open pit mine. Open pit mining is carried out on a seven day week production basis.

Standard drilling and blasting techniques are used in hard rock along with free digging in soft areas. Selected blast holes are sampled and assayed for production grade control purposes in hard rock, and trench sampling is conducted in soft areas.

Processing Technologies

  • Gravity separation
  • ROM/dump leach
  • Carbon in leach (CIL)

Summary:

Broken and freely dug rock is loaded with an excavator into haul trucks. Depending on the block model determination or grade control results, the mined material is delivered to the run of mine pad, primary and secondary crusher, low-grade stockpile, or to waste rock dumps. The predominant method of gold recovery is via carbon in leach technology, with some gold recovered via a gravity circuit.
