Andrada sees lithium potential in Namibia

14 march 2024

Andrada Mining, an African technology metals mining company with a portfolio of mining and exploration assets in Namibia, says preliminary modelling indicates an initial production of 30,000 tpa from 1.7 million tonnes per annum run-of-mine of technical grade petalite concentrate.

Company chief executive Anthony Viljoen said there is potential offered by the lithium production opportunities.

“In the short-term, we are targeting initial sales of our pilot plant production into the spot glass-ceramics market whilst progressing discussions with potential long-term off-takers across the lithium value chain to access other markets, particularly the battery market,” he said.

“The integration of petalite production will create further value for our shareholders and solidify our position as a key producer in the technology metals industry.”

Viljoen said exploration drilling programmes are ongoing across all assets to expand the size and scope of the mineral resources.

He said the collaboration between their exploration and metallurgy teams expedites test work to facilitate the transition of projects from exploration to development and, ultimately, production.
