Abstract. The Nkout (Cameroon) and Putu (Liberia) oxide facies iron ore deposits comprise fresh magnetite banded iron formation (BIF) at depth, which weathers towards the surface, forming high grade martite–goethite ores. This study aimed to improve the mineralogical understanding of these deposits in order to predict their metallurgical

· Precise evaluation of the grade in various sections of the deposit is highly dependent upon building a robust 3D model of the ore deposit (Li et al. 2010; Rezaei et al. 2019c). The main goal of grade modeling is at providing a quantitative definition of the variables distributed in space (Isaaks and Srivastava 1989 ).
