The mineralogical investigation of a number of polished blocks showed the dominance of braunite accompanied by pyrolusite and cryptomelane. A number of mineral assemblages are recommended. The significant ore textures are, banding, replacement and colloform, while other textures identified are veined, granular, brecciated, relict, open space, and mutual boundary relationship.
