Ghana has indeed surpassed South Africa to become the continent'

That's correct! Ghana has indeed surpassed South Africa to become the continent's largest gold producer. This shift in rankings reflects the changes in the gold mining industry across Africa. South Africa has historically been the largest gold producer in Africa, but over the years, its gold production has been declining due to various factors such as aging infrastructure, high production costs, and labor issues. On the other hand, Ghana has seen a significant rise in its gold production, driven by new investments, favorable government policies, and the development of new mining projects. The other countries you mentioned, Mali, Burkina Faso, and Sudan, are also significant gold producers on the continent, contributing to Africa's overall gold output. The gold mining industry is a crucial part of the economies of these countries and plays an important role in their GDP and foreign exchange earnings.
