Marula Mining, a company focused on the extraction of strategic metals in Africa, has announced that recent assay results have confirmed the presence of high-grade copper in concentrates stored at the Kinusi mine, located in the Mpwapwa district, Tanzania.
High-grade copper confirmed in assays
The analyses, carried out by an internationally renowned independent laboratory, showed an average copper content of 21.54% in three 10-kilogram samples taken from the open pit Kinusi No. 4. Individually, the assays reported values of 20.21%, 21.77% and 22.64% , confirming the richness of the mineral present in the mining operation.
These results strengthen ongoing marketing arrangements, with plans to export up to an initial 1,000 tonnes of copper concentrate to buyers in Switzerland, the UK and China-based commodity trading groups. Marula Mining said shipments were planned for 31 January 2025 but have been slightly delayed while sales arrangements are finalised following confirmation of assays.
Development of the processing plant
The data obtained from the tests will be essential to optimize the design and operation of the processing plant in Kinusi , structured in two phases. The first includes a gravity concentration circuit, coarse jigging and fine dehydration, with a projected capacity of 24,000 tons of copper concentrate per year . Its commissioning is expected to be completed this quarter.
In the second phase, Marula Mining will implement a heap leaching circuit with hydrometallurgy and solvent extraction, as well as a refining process using electrowinning. This scheme will allow the initial production of 10,200 tons of copper cathodes per year, ensuring greater efficiency and profitability in the mining operation.
Marula Mining Outlook and Strategy
Marula Mining continues its development and expansion strategy in Africa, focusing on strategic metals for the global energy transition. The company maintains assets in lithium, tantalum, manganese and graphite projects in South Africa, Kenya and Tanzania, reinforcing its commitment to sustainable and responsible production.
The confirmation of high-grade copper at Kinusi represents a key step in strengthening its market presence and ensuring compliance with strategic commercial agreements in the global mining industry . Marula Mining will soon announce the completion of the first shipments of copper concentrate, consolidating its position as a relevant player in the production of essential metals.
