The purpose of the initial stages of exploration is to reduce the size of the area, say from 400–500 km 2 to a working area of around 2–3 km 2.As it is impossible to reduce it in one go and exploration is quite an expensive exercise, multiple stages must be planned meticulously to eliminate useless areas and concentrate on areas of real interest.
