Yaramoko Mine, Burkina Faso

Our highest grade gold mine


Our Yaramoko Mine is in the Houndé greenstone belt region in the Province of Balé in southwestern Burkina Faso. In 2023, Yaramoko produced 117,711 ounces of gold.

The Yaramoko Mine consists of two underground gold mines: the 55 Zone and Bagassi South. The deposits are greenstone-hosted high-grade orogenic gold deposits. The Bagassi South Zone deposit is located 1.8 kilometers south of 55 Zone and the surface definition of the veins can be traced over a strike length of 800 meters and dips to the northeast. Gold typically occurs as coarse free grains in quartz and is associated with pyrite.

Based on reserves reported as of December 31, 2023 the operation has a mine life of two years.

We recognize the role that the Yaramoko Mine plays to support sustainable development in our areas of influence around the mine. In 2023, we employed 896 direct employees and contractors.

The Yaramoko Mine is situated in the Houndé greenstone belt region in the Province of Balé in southwestern Burkina Faso. The property is located approximately 200 kilometers southwest from the capital city of Ouagadougou (Latitude: 11° 45’ 25” N, Longitude: 3° 16’ 58” W).

Our operations add value to Burkina Faso’s formal economy by providing contracts and stable jobs for local people and by helping to expand the revenue base of our host government through income taxation, national social security system contributions and the royalties we pay every time we ship gold.

Geology and mineralization

The north-northeast-trending Boni shear zone divides the Yaramoko concession between the predominantly Houndé volcanic and volcaniclastic rock to the west and the Diébougou granitoid domain composed predominantly of granitic rock with minor volcanic rock to the east. The main lithological units are mafic volcanic rocks, felsic intrusions, and late dolerite dikes.

This region is considered prospective for orogenic gold deposits, which typically exhibit a strong relationship with regional arrays of major shear zones. The largest granitic intrusion found on the Yaramoko concession is host to both the 55 Zone and Bagassi South Zone gold deposits. Both deposits are set on the eastern margin of the intrusive in the footwall of the Yaramoko shear along conjugated dextral faults located in extensional position to the regional shear zone. The bulk of the gold mineralization occurs in dilatational segments of the shear zones where quartz veins are thicker and exhibit greater continuity.

Brownfields exploration

The Brownfields exploration program budget for 2024 at Yaramoko is $6.1 million, which includes 41,450 meters of exploration drilling, with underground drilling testing western and depth extensions to the Zone 55 deposit, surface drilling testing several anomalies along the Boni Shear, Bagassi South surface extensions, and other surface targets.
