Mine Life3 years (as of Jan 1, 2017)
Afrique Gold acquired the Bonikro gold mine from the Australian group Newcrest Mining Limited in March 2018.

No public production data has been available since then.

On March 1, 2021, Endeavour completed the sale of its interest in the non-core Agbaou mine in Côte d’Ivoire to Allied Gold Corp ("Allied Gold") for a consideration of up to $80 million with further upside through equity exposure in Allied Gold and a Net Smelter Return royalty.

Allied Gold is a private African operator which notably owns the nearby Bonikro mine. As a result of the transaction, the Bonikro-Agbaou operation was created. The Bonikro-Agbaou operation is comprised of multiple open pits, two processing plants with a total milling capacity of over 5Mtpa, and have the potential to produce over 285,000 ounces annually.

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.


Crushing and Grinding


Processing

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

Source: Subscription required

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.
