The Kibali gold mine in the Haut-Uele province of northeast Democratic Republic of Congo is a standout example of how Barrick’s self-powered microgrid infrastructures are configured to sustainably deliver cheaper energy with reduced environmental impact. |

The mine is owned by Kibali Goldmines SA (Kibali) which is a joint venture company effectively owned 45% by each of Barrick and AngloGold Ashanti, and 10% by Société Miniére de Kilo-Moto (SOKIMO). The mine is operated by Barrick.

Summary:
Geological Setting
The Kibali deposits are hosted within the Kibali Greenstone Belt (otherwise referred to as Moto granite- greenstone terrane), bounded to the north by the West Nile Gneiss and to the south by plutonic rocks of the Watsa district. The Kibali Greenstone Belt is an elongate west-northwest-east-southeast trending terrane containing Archean aged volcano-sedimentary conglomerate, carbonaceous shales, siltstone, banded iron formations, sub aerial basalts, mafic intermediate intrusions (dykes and sills) and multiple intrusive phases that range from granodiorite to gabbroic in composition. Based on textures and types of lithologies present in the stratigraphy, the rocks within the Kibali permit area are interpreted as having been laid down in an aqueous environment.
The majority of the primary lithologies are clastic (sedimentary) in origin, possibly being developed in a regional extensional environment such as a rift graben or half graben. At Kibali, the gold deposits are largely hosted in siliciclastic rocks, banded iron formations, and cherts that were metamorphosed under greenschist facies conditions, situated along a curvilinear zone 20 kilometers long and up to one kilometer in width, known as the “KZ Trend”. Gold mineralization is concentrated in gently northeast to north-northeast-plunging fold axes whose orientations are generally parallel with a prominent lineation in the mineralized rocks.
The Kibali deposits differ from many orogenic gold deposits as t ........

Summary:
The Mine comprises both open pit and underground mining operations.
The Project consists of multiple mineral deposits including; an underground mine at KaragbaChauffeur-Durba (KCD); active open pits at KCD, Sessenge, Aerodrome and Gorumbwa; a partially depleted open pit with planned push backs at Pakaka; depleted open pits with further potential at Kombokolo and Mengu Hill; planned new open pits at Pamao, Megi-Marakeke-Sayi, Kalimva, Ikamva, and Oere, plus deposits under evaluation at Mengu Village and Sessenge SW.
Open-pit
As of December 31, 2022, the operational pits were Pamao, Gorumbwa, Sessenge and Aerodrome. The Mengu Hill, Mofu, Kombokolo and Rhino pits were depleted in 2017.
Open pit mining is conducted by the contractor Kibali Mining Services, a local DRC company, using either free-dig or conventional drill, blast, load, and haul methods. The mining equipment is ultimately jointly owned by Barrick and the contractor’s parent company, the Bouygues Group.
From 2023 onwards, open pit production will come from the Sessenge, Aerodrome, Pamao, Gorumbwa, Megi-Marakeke-Sayi, Kalimva-Ikamva, Oere, Pakaka, and KCD deposits. As all of the pits are characterized by the presence of a near-surface groundwater table with the potential for high groundwater inflows into the pits, a system of pumping and dewatering trenches is established prior to the commencement of mining in each of the pits, preventing the inflow of any surface water to the active mining areas.

Reserves at December 31, 2022:
A price of $1,300/oz was used by Barrick to estimate the Kibali Mineral Reserve. Pamoa Main pit was based on a gold price of $1,400/oz and Pamoa South pit was based on a gold price of $1,500/oz. Mineral Reserve Cut-off grade: Open pit - 1.5 g/t Au, Underground - 1.96 g/t Au, Stockpile - 1.5 g/t Au.
A price of $1,700/oz was used by Barrick to estimate the Kibali Mineral Resource.
