The world’s primary chromium ore resources are concentrated in South Africa’s Bushveld Complex and Zimbabwe’s Great Dyke, where chromitite is found in thin stratiform layers. In the Bushveld Complex, these layers are classified into three groups: Lower Group (LG1–LG7), Middle Group (MG1–MG4), and Upper Group (UG1–UG2).
The Black Chrome Mine is located in the Eastern Limb of the Bushveld Complex, specifically mining the LG6 chromitite layers. The deposit features two prominent reefs, LG6 and LG6A, recognized for their shallow depth and high-grade quality. These reefs dip 14° to 16° west, have an average thickness of 2.2 meters, and contain an 80-centimeter waste partition.
The high in-situ grade of over 44% Cr₂O₃ with a Cr/Fe ratio of over 1.5 ensures a substantial yield of high grade concentrates. As of August 2020, the mine holds an estimated 18 million tonnes (Mt) of chrome resources and 9 Mt of reserves.





The Black Chrome Mine is a well capitalised developing underground chrome mine having a resource base of 18 million tonnes of chrome ore.
