Lenses of high- grade hematite ore formed by processes of secondary enrichment are associated with belts of Precambrian (Kibalian) itabirites in the upper Ituri river basin (Kilo region), where an estimated 889 million metric tons of ore averaging over 45 percent Fe are present, and in the upper Uele basin (Moto region), where there are 1,348 million tons averaging over 68 percent Fe.
