Introduction
West Africa is home to some of the most significant gold deposits in the world.
Countries like Ghana , Mali , Burkina Faso , and Guinea sit atop vast mineral-rich geological belts.
These deposits have fueled economies for centuries — from ancient trade empires to modern mining industries.
Key Gold Regions in West Africa
Several major gold-producing zones exist across the region:
- Birimian Greenstone Belts – Found mainly in Ghana, these are among the richest gold-bearing formations in Africa.
- Kédougou-Kéniéba Inlier – Located in eastern Senegal and western Mali, this zone hosts large-scale mines.
- Yamoussoukro Belt – Found in Ivory Coast, it shows potential for future gold development.
- Siguiri Basin – In northeastern Guinea, this area has been producing gold since the early 20th century.
Types of Gold Deposits
Two main types of gold deposits are found in the region:
1. Orogenic Gold Deposits
- Formed deep underground by tectonic activity
- Found in greenstone belts
- Examples: Siguiri (Guinea), Loulo-Gounkoto (Mali)
2. Placer (Alluvial) Gold Deposits
- Eroded gold particles found in riverbeds and sediments
- Easily mined using simple tools
- Common in artisanal mining areas
Major Gold Mines in the Region
Some of the largest active gold mines include:
| Mine Name | Country | Operator |
|---|---|---|
| Ahafo Mine | Ghana | Newmont Corporation |
| Iduapriem Mine | Ghana | AngloGold Ashanti |
| Loulo-Gounkoto | Mali | AngloGold Ashanti |
| Essakane Mine | Burkina Faso | IAMGOLD (now Equinox) |
| Siguiri Mine | Guinea | Teranga Gold |
These mines contribute billions of dollars annually to national economies.
