K.Hill manganese project, Botswana
Name of the Project
K.Hill manganese project.
Location
The Kanye Basin, in south-eastern Botswana.
Project Owner/s
Giyani Metals Corp.
Project Description
A preliminary economic assessment (PEA) has demonstrated the strong potential of the project. The PEA is based on an estimated mineral resource, at a cutoff grade of 18% manganese oxide, of 1.1-million tonnes grading 31.2% manganese oxide, 8.9% aluminium oxide, 26.3% silicon dioxide and 16.9% iron (III) oxide.
The project envisages an operation with a nine-year life-of-mine, producing 245 000 t of high-purity electrolytic manganese metal.
The PEA proposes traditional truck-and-shovel mining methods. The proposed process for the production of electrolytic manganese metal includes comminution, leaching, solid/liquid separation and solvent-extraction, as well as electrowinning and refining.
Potential Job Creation
Not stated.
Net Present Value/Internal Rate of Return
The project has a pretax net present value, at a 10% discount rate, of C$491-million and an after-tax internal rate of return of 90.6%, with a payback of 1.5 years.
Capital Expenditure
Preproduction capital expenditure is estimated at $369-million.
Planned Start/End Date
The project aims to break ground in July 2020.
Latest Developments
Giyani plans to continue hydrometallurgical testing, with electrorefining to produce high-purity electrolytic manganese metal samples for testing by battery makers.
It will also progress with a definitive feasibility study to upgrade K.Hill into a mineral reserve.
Key Contracts and Suppliers
SRK Consulting (PEA).
