Tin, tantalum and now lithium mining company recalled how it had looked across African jurisdictions when initially pursuing tin- mining opportunities and had found Namibia to be a cut above.
According to Andrada Mining’s Chief Executive Officer, Anthony Viljoen, Namibia is the best jurisdiction in Africa to mine. “Namibia is easy stock. I’m a miner not a politician, but I can tell you that Namibia’s a very happy place for our money. I can’t say enough good things about being invested in Namibia and Namibia’s geology is fascinating, the Erongo region in particular,” said Viljoen.
Erongo is one of the 14 regions of Namibia. Its capital, Swakopmund, is named after Mount Erongo, a well-known landmark in Namibia and in this area. Erongo contains the municipalities of Walvis Bay, Swakopmund, Henties Bay and Omaruru, as well as the towns Arandis, Karibib and Usakos.
Viljoen added, “You’ve got these pegmatite belts, which are not uncommon. But these pegmatite belts are quite unique in Namibia in that they run for hundreds of kilometres, east and west, and they swarm all the way up and down the coast.”
Usually, pegmatite belts pinch out after a couple of hundred metres to a kilometre, but Namibia’s are just incredibly long and incredibly thick, hundreds of metres thick. He noted, “When we picked up the licences, we picked up the old licence areas because there was a lot of geological data and the biggest of those old mining areas was the old Uis tin mine, that was once an Iscor asset.”
Iscor was formerly South Africa’s State-owned steelmaking enterprise that was unbundled and sold.There was a huge amount of data that allowed Andrada, formerly AfriTin, to get stuck in.What the old-timers would do is they would follow the pegmatite belts, find where they outcropped and open a pit.
As they mined over 12 historic pits, Andrada had the benefit of that historic reserve. It did a confirmatory drilling programme concurrent with developing the plant and at the biggest of the historic pits, it did down dip extensions, to find that the orebody was 70% bigger than had been historically declared.
The company also tested for a variety of different elements that are typically within pegmatite and what it found was that associated with one of the biggest tin deposits by inventory size was also one of the biggest lithium deposits. It still has another 900 holes to confirm, which were displayed on a satellite image.
“Where this becomes just so fantastically huge for us is that all those orange marks on the satellite image are pegmatite. We’ve got another 180 outcropping pegmatites within our licence area. The extent of our mineralisation is huge,” shared Viljoen.
Andrada has gone into production on a shoestring with the help of South African engineers and has embarked on an expansion project to increase capacity and become a polymetallic producer of lithium, tin and tantalum. Steps are now being taken to sell the lithium concentrate being produced into industrial and chemical markets. “By far amongst everything we’re doing, lithium is really taking centre stage,” concluded Viljoen.
