Kgwakgwe Hill – Botswana
The Kgwakgwe Hill project covers a supergene system containing high-grade manganese nodules. Manganese ore mined from 1957 to 1967 at Kgwakgwe Hill consisted almost entirely of such high-grade manganese oxide nodules grading 40-50% total manganese (Source: Botswana Notes and Records, Vol.30, p. 147-156).
The deposit lies within the Kanye Basin, which is underlain by rocks of the Transvaal Supergroup (“Transvaal”). The Transvaal hosts roughly 80% of the world’s manganese reserves and has been identified in Botswana both under cover beneath Kalahari sands and in local outcrop within the project area. This deposit is of particular interest to Giyani because it is proof of concept that manganese deposits exist in Botswana and that the manganese displays simple yet ideal chemical compositions and grade characteristics that would be attractive to battery manufacturers.
