Another thing about Nigeria's orogenic gold is that it is shallow. Let me talk about the Bauchi gold, the latest find. Once you dig for about 15metres, you start getting to the regolith. By 30 metres, you get to the lateritic or ferrugenised iron-regolith. In Ghana, you have to go about 500metres or 1kilometre to get to that.
