Andrada Mining Limited has reported high-grade lithium results from its Lithium Ridge project in Namibia, reinforcing the area’s potential to host a significant lithium resource.
The results follow a surface sampling and geological mapping programme carried out in partnership with Sociedad Química y Minera de Chile (SQM).
According to Andrada chief executive officer Anthony Viljoen, the programme identified multiple high-grade lithium-bearing pegmatites. Grab samples returned lithium oxide (Li₂O) values exceeding 4%, with a peak grade of 4.67%.
The primary lithium mineral was confirmed as spodumene, consistent with previous drilling results.
The sampling also highlighted the project’s polymetallic potential, with notable tin (Sn) and tantalum (Ta) by-products. Individual samples returned grades of up to 3.12% Sn and 905 parts per million Ta.
Viljoen said the findings point to meaningful upside beyond the company’s existing operations.
“While expansion activities at our flagship Uis Mine continue to progress, Lithium Ridge demonstrates the potentially significant regional upside within Andrada’s broader portfolio,” he said.
“We look forward to receiving the first assay results from the Lithium Ridge Stage 1 drilling programme, which is advancing on schedule.”
More than 1,500 pegmatites were mapped during the programme, extending the known mineralised trend to approximately six kilometres and indicating the presence of a potentially larger lithium system.
Of the 496 samples analysed, 115 returned Li₂O grades above 1%, while 156 samples recorded significant tin content and 165 showed elevated tantalum levels.
The company said the results provide strong validation for its ongoing Stage 1 drilling programme at Lithium Ridge, which has now mobilised a third diamond drill rig.
The programme is designed to test the depth and continuity of the mineralised pegmatites along strike.
“The results from Lithium Ridge represent a very encouraging validation of the project’s lithium potential,” Viljoen said.
“Surface samples returning lithium grades in excess of 4% Li₂O, together with confirmation of spodumene as the primary lithium mineral, reinforce our view that Lithium Ridge hosts a large, high-quality lithium system.”
