Modern Mining June 2019In this month’s issue we have a regional focus on West Africa, in which we cover the Wahgnion and Sanbrado gold projects, both currently under construction in Burkina Faso, the planned Namdini gold mine in Ghana and the Mako gold mine in Senegal, now in its second year of operation and consistently beating its budgets.

We also look in this issue at two of the more unconventional solutions to powering mines in Africa – hydropower plants and hybrid plants. The best – and possibly the only – example in Africa of the effective use of hydropower at a mine is provided by Kibali in the DRC while the most recent hybrid power installations, combining solar and genset generation of electricity, are at the Essakane and Otjikoto gold mines in Burkina Faso and Namibia respectively.
