Konongo Tarkwaian Rocks

Birimian - Wikipedia

The Birimian rocks are major sources of gold and diamonds that extend through Ghana, Côte d'Ivoire, Guinea, Mali and Burkina Faso They are named after the Birim River, one of the main tributaries of the Pra River in Ghana and the country's most important diamond-producing area Ghana and Mali are the second and third largest producers of gold in Africa, respectively
