Andrada Mining Limited has reported positive early test results at its Brandberg West project, showing potential to increase production of tungsten, tin and copper.
The company said the tests focused on processing old mined material and waste from the historic Brandberg West mine, as well as ongoing exploration at the site.
Results show mineral quality improved after processing. Tungsten increased from 0.24% to 1.45%. Copper rose from 0.73% to 2.81%. Tin increased from 0.31% to 2.09%.
The tests also showed high recovery rates. Tungsten recovery reached up to 91%, while tin recovery reached up to 94%.
The process reduced the amount of material needing further treatment by about 90%.
The company said this could lower costs and speed up production.
Andrada used sensor-based technology to separate valuable minerals from waste. It said the results confirm it can extract multiple metals at the same time and produce a higher-value product.
Andrada chief executive officer Anthony Viljoen said the results show the economic potential of tungsten at Brandberg West.
He said the grades from previously discarded material are higher than global averages, which supports further development of the project.
The company said tungsten is becoming an important part of its operations in Namibia.
It added that Namibia’s mining sector holds key materials used in batteries and new technologies, with the Damara Belt identified as a strong resource area.
At its Uis Mine, Andrada said it has lithium, tin and tantalum resources estimated at 138 million.
The company produces tin and tantalum concentrates under agreements with Thaisarco and Afrimet.
It is also producing lithium for bulk testing with potential buyers.
