Name of the Project
K. Hill manganese project.

Location
The Kanye basin, in south-eastern Botswana.

Project Owner/s
Giyani Metals Corp.

Project Description
The project is expected to produce 891 000 t of high-purity manganese sulphate monohydrate over its ten-year mine life.

Potential Job Creation

Latest Developments
Giyani Metals Corporation has, through Mintek, in South Africa, completed enhanced metallurgical testwork and final process flowsheet design as part of its feasibility study on the K.Hill manganese oxide project.

However, because this phase of testwork does not include crystallisation, a specialist engineering firm has been engaged to undertake crystallisation testwork to finalise the process flowsheet for the feasibility study and the demonstration plant.

Once the process flowsheet is finalised, Giyani will contract an engineering firm for the construction of the demonstration plant.

Following a peer review of the process flowsheet, Giyani anticipates that the design-build contract for the demonstration plant will be signed with the objective for the plant to be operational in the first half of 2022.

Giyani CEO Robin Birchall has said that the demonstration plant will produce about 250 kg/d of final high-purity manganese sulphate monohydrate product to share with potential customers for preliminary product testing, and that “we are already assembling interested parties”.

Key Contracts, Suppliers and Consultants
Mintek (metallurgical testwork) and SRK Consulting ((updated mineral resources estimate).
