Globe Metals and Mining enlists 6 vendors to complete Feasibility Study and refinery design at Kanyika

Globe Metals and Mining (ASX:GBE) has appointed 6 ‘highly experienced’ vendors to complete a Feasibility Study and a final refinery design for its Kanyika Niobium Project in central Malawi.

The company reports Johannesburg-based Solo Resources has been enlisted to design and construct the mineral processing plant and undertake gravimetric testing on the ore to discard gangue before milling. Solo has a ‘wealth of experience’ in designing, building, and commissioning mineral plants in South Africa and across Africa.

Meanwhile, TCM Research has been selected to design the refinery process for the Kanyika concentrate and to determine the design parameters of the refinery. 

Globe reports TCM has worked with more than 10 different ore concentrates that contain niobium and tantalum and has also processed concentrates containing platinum group metals (PGM), rare earths, gold, tin, vanadium, iron, tungsten, zircon, hafnium, nickel, and copper sulphides, as well as low levels of radioactive material including uranium, thorium, and other fission daughter products.

Once the design parameters for the refinery are set, South African engineering business The Resonant Group will complete the engineering drawings for the refinery. Globe says Resonant has completed engineering work across the metals, minerals, chemicals, oil and gas, and infrastructures across the Americas, Europe, Asia, and the Middle East.

Globe reports it has enlisted Geolabs Global as the laboratory to process ore from Kanyika into a concentrate. The company says Geolabs is a ‘global leading provider’ of mineral processing solutions for the mining and minerals industry based in South Africa.

For phase one of the project, the company has selected Malawi-based construction company S.R. Nicholas to provide the preliminary design and civil engineering of the plant.

Additionally, Globe reports South African-based Energy and Densification Systems (EDS) has been developing a horizontal, multi-shaft mill that has a ‘significantly lowered’ power consumption to an equivalent semi-autogenous grinding (SAG) ball mill since 2016.

The EDS mill produces crushed ore smaller than 1mm that is ‘ideal’ for gravity spiral separation, which Globe expects to allow some gangue to be discarded prior to reaching the ball mill.

In the revised flowsheet, Globe expects both capital and operating expenditure to be reduced by about 10%

In the revised flowsheet, Globe expects both capital and operating expenditure to be reduced by about 10%, while the final cost savings will be published in the revised Feasibility Study. This study is expected to be published in Q1 2024 once the refinery design has been finalised and all vendors have had their cost estimates verified and finalised for execution.

Globe also reports a 12-tonne bulk sample has been extracted from a surface outcropping at the point of the phase one pit shell as outlined in the Definitive Feasibility Study (DFS) mining plan where mining will start.

The sample was transported to Lilongwe, where it was crushed to smaller than 40mm before being exported to South Africa to be further crushed to smaller than 1mm by EDS.

Once the sample has been crushed down to this size, half will be sent to Solo for gravimetric testing, while the other half will be sent to Geolabs for milling, de-sliming, and magnetics removal before flotation to produce a concentrate. This concentrate will then be sent to TCM for chlorination testing.

Globe Metals and Mining is a Perth-based explorer focused on its Kanyika Niobium Project in central Malawi, Africa. The project comprises a single large-scale mining licence that grants the company the right to mine niobium, tantalum, and deleterious uranium.

The company says 33.8km of percussion and core drilling has been completed at the project to define the extent of mineralisation. As per its latest quarterly report, Globe had $543,000 cash in the bank as of 31 March 2023.
