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.
We are pleased to announce that our initial surface sampling program conducted at the historic Kgwakgwe Hill Manganese Mine l confirms high grade mineralized shale grading 58-61% MnO.
A complete table of all sample results is included in Appendix A.
Highlights of all sample results:
Samples KAN/01/2017 and KAN/02/2017 were collected from a surface outcrop in an unexploited mineralized zone to the north west of the Kgwakgwe open pit called the “Quarry Zone”.
Samples KAN/03/2017 and KAN/04/2017 were collected from a mineralized outcrop 120 m to the south west of the Quarry Zone called the “Crushing Pad”.
Samples KAN/07/2017 and KAN/08/2017 were collected from a mineralized section in the west wall of an old quarry to the south east of Kgwakgwe Hill Open Pit.
Samples KAN/05/2017 and KAN/06/2017 taken from the hanging wall in the pit.
The phase I sample results exceeded our initial expectation as they graded well above those found in other manganese projects currently being investigated by the Company. The low percentage of deleterious elements is an indicator that the manganese found in this deposit could be ideal for use in the battery industry.
Giyani is also pleased to announce the commencement of phase II regional sampling and mapping of our extensive property in an initial attempt to estimate the potential size of this high-grade manganese deposit. Our geological team started phase II on June 9th and is currently sampling and mapping an area that stretches 74 Km diagonally from Kgwakgwe Hill to the north east
