Giyani completes K.Hill manganese oxide project test work - Construction Review

As part of its feasibility study on Botswana’s K.Hill manganese oxide project, TSX-V-listed manganese developer Giyani Metals Corporation has completed increased metallurgical test work and final process flowsheet design through Mintek in South Africa.

Because this phase of testing does not involve crystallization, a professional engineering firm has been hired to conduct crystallization tests to complete the process flowsheet for the feasibility study and demonstration facility.

Giyani will begin hiring an engineering firm to build the K.Hill manganese oxide project’s demonstration facility once the process flowsheet is finalized.

Giyani expects to execute a design-build contract for the demonstration plant after a peer evaluation of the process flowsheet. The unit is expected to be operational in the first half of 2022.

According to Giyani CEO Robin Birchall, the demonstration facility would generate roughly 250 kg of final high-purity manganese sulfate monohydrate (HPMSM) product per day, which will be shared with potential clients for preliminary product testing.

Otse, Botswana

So far, 26 RC holes have been drilled at Otse South, near ancient mine workings and characterized by a northwest-southeast chargeability anomaly.

Almost every hole drilled thus far has revealed visible mineralization, validated by portable X-ray fluorescence investigation. The greatest results have been 48% manganese oxide at depths...
