Giyani Greenstone Belt (GGB) is 17 km wide and has a strike length of 70 km. The belt has an overall NE-trend, but to the west, the GGB splits into a northern Khavagari arm and a southern Lwaji arm separated by granitoid gneiss (the Klein Letaba Gneiss) and younger granite. The Lwaji arm has more or less the same trend as the main part of the belt but the Khavagari arm has been rotated into an E-W orientation. The GGB is a shallow structure with a down dip extension of around 1.5km in the NW and 4km in the SE. The predominant rocks in the project area include the ultramafic (tremolite) schists; mafic (chlorite) schists which are common throughout the belt. Also present in the area are the metasedimentary rocks which comprise Banded-Iron-Formation (BIF), quartzite, metapelite and rare dolomite. Although these formations are discontinuous, they form important structural markers throughout the belt. They are best developed in the northern sections including the Khavagari arm and the clastic metasedimentary rocks with obvious primary structures are abundant along the Nsama River in the central part of the belt. The supracrustal rocks of the GGB have been subjected to amphibolite facies metamorphism. Peak metamorphism was followed by uplift and the influx of CO2 rich aqueous fluids. This rehydration event occurred during the exhumation of the Limpopo Complex along the Hout River Shear Zone and was responsible for shear-zone hosted alteration of the rocks in the GGB and the formation of the orogenic gold deposits. (Mineral Resources of South Africa - The Giyani Gold Project Scoping Report 2020)

There are 55 known gold occurrences of which 20 are inactive mines and 35 are prospects.
