SRK KZ was commissioned by Giyani Metals Corporation to undertake a Mineral Resource Estimation (MRE) and Pre-liminary Economic Assessment (PEA) of the Kgwakgwe Hill (K-Hill) Manganese project in the Republic of Botswana.
K-Hill is located next to the town of Kanye, known as the administrative centre of the southern district of the Republic of Botswana in southern Africa. The entire project area extends over 2,618 square km of tenements, with the K-Hill project in a 444 square km license area.
The manganese mineralisation at K-Hill occurs primarily as a supergene enriched manganiferous shale (the upper Mn-shale) occurring in the upper portion of a shale horizon within the Black Reef Quartzile Formation of the Transvaal Supergroup. The upper Mn-shale which hosts the MnO mineralisation, varies between 2 m and 12 m thick, dips shallowly (5-10°) and has a delineated extent of 900 m N-S and 350 m E-W.
The MRE has been classified according to the Canadian Institute of Mining, Metallurgy and Petroleum best practice guidelines and is reported in accordance with the 2014 CIM Definition Standards. As of March 2021, the MRE comprises 1.7 Mt of open pit ore at 25.7% MnO, of which 1.1 Mt is classed as high-grade upper Mn shale.
The metallurgical studies have indicated that the mineralised material is amendable to reductive acid leaching. This can be processed using a flowsheet that consists of an acid leach, followed by solution purification, solvent extraction, and vacuum crystallisation for the production of a high purity manganese sulphate monohydrate product (HPMSM). This will be a suitable for sale into the battery market.
SRK has assembled a team of experts to cover all aspects of the project as a Feasibility Study is in progress.
