Potential low-grade iron ore deposits in

Exploitation of low-grade iron ore would be quite unique in a South African context as South Africa is well endowed with high-grade iron ore resources. Low-grade iron ore, defined as containing between 20 and 47% iron, is thought to be the primary iron-bearing lithology from which most high-grade ore deposits formed, through different processes of enrichment.

The iron ore is massive coarse-grained hematite-magnetite rock in a folded layer, 30 meters thick, in Precambrian gneiss. Mineralogic, textural, structural, and oxygen isotope data indicate that the hard ore represents a pre-metamorphic concentration of iron that was later deformed and metamorphosed, rather than a concentration during metamorphism.
