Giyani Metals Corp. (TSXV:EMM, GR:A2DUU8) (“Giyani” or the “Company”) is pleased to announce that as part of the ongoing Feasibility Study (“FS”) work, a processing trade-off study (“Study”) has been completed for its K.Hill manganese project in Botswana (the “Project”). The results from the Study do not materially change the robust project economics from the Project’s Preliminary Economic Assessment, as announced on 28 April 2020 (“PEA”).


  • The post-tax Project net present value at a 10% discount rate (“NPV”) from the PEA is US$275m ($359m), with an IRR of 82% and a capex of US$110m ($143m).
  • The operating and capital cost estimates modelled in the Study are in-line with those used in the PEA. Therefore, the Project NPV is unchanged and continues to be robust.
  • The Study was conducted by Tetra Tech, together with Royal IHC, (the “Engineering Consultants”) to identify the optimal processing route for the Project in the FS.
  • The Study only focussed on the reductant phase of the process, which occurs upstream of solvent extraction and electrowinning. The following three reductive leaching processes were considered;
       º   Sulphur dioxide (SO2)
       º   Sulphuric acid leaching with reducing sugars
       º   Carbothermic reduction (rotary kiln), followed by sulphuric acid leaching
  • The PEA assumed a sulphuric acid and reducing sugar-based process. The Study assessed two additional alternatives, as well as the PEA process. The study showed that the sulphur dioxide based process is the optimal route, as there is less process risk. The operating costs and capital associated with this route were also in line with those modelled in the PEA. Therefore, the sulphur dioxide process has been selected for the FS.
  • There is no alternative trade-off to the solvent extraction and electrowinning process for the production of high purity electrolytic manganese metal (HPEMM).

The study included a financial comparison of the three process options, taking into consideration capital cost, operating cost, recovery and incremental NPV over a 10-year Project life. The Engineering Consultants’ analysis also included qualitative considerations such as flow sheet simplicity, level of complexity, security of reagent supply and market acceptance.

The PEA is considered preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and accordingly there is no certainty that the preliminary economic assessment will be realized. The expected accuracy of costs in the PEA is within a -35% to +45% level of confidence, as is appropriate for the level of study and accuracy of the input data provided.

Mineral Resources that are not Mineral Reserves do not by definition have demonstrated economic viability.

Robin Birchall, CEO of Giyani Metals Corp. commented:

“I would like to congratulate the Giyani team and the Engineering Consultants for their work on the Study. The change in the reductant process means that we have reduced our process risk, without any increase to capital or operating costs. We are fortunate that our process is simple, thanks to the deposit’s grade, quality and proximity to the processing plant.

Following recent insights into the direction that cathode manufacturers and battery electric vehicle manufacturers are moving, we will update the PEA in due course to include high purity manganese sulphate monohydrate (HPMSM) as an additional product stream. We expect to further increase the NPV, as well as improve the operating and capital costs as a result of this work.

The Engineering Consultants will also be including the addition of HPMSM into the FS, which will be released after the updated PEA, expected in H1 2021.”
