Andrada Mining has reported another set of high-grade lithium drill results from its Lithium Ridge project in Namibia, with assays returning grades of up to 3.46% lithium oxide (Li₂O), further strengthening the project’s potential as a significant critical minerals development.
Andrada Chief Executive Officer, Anthony Viljoen, said the latest results from six additional diamond drill holes confirmed consistent high-grade lithium mineralisation from surface and at depth.
The standout result came from drill hole LRD027, which intersected 9.05 metres grading 2.28% lithium oxide between 50.82 metres and 59.87 metres, including a higher-grade interval of 3.97 metres grading 3.46% lithium oxide.
“We continue to receive exciting results from the recently completed drill programme at Lithium Ridge. Intersection grades of up to 3.46% Li₂O near surface demonstrate exceptional quality and scale, reaffirming our conviction in the potential of the asset,” Viljoen said.
Other notable intersections included 13.27 metres grading 1.42% lithium oxide in drill hole LRD024 and 9.64 metres grading 1.24% lithium oxide in drill hole LRD023. The results form part of an expanded Stage 1 drilling programme undertaken in partnership with global lithium producer SQM.
In addition to lithium, the drilling campaign confirmed the presence of associated tin and tantalum mineralisation across all holes, potentially enhancing the project’s economic viability through additional revenue streams. Drill hole LRD029 returned 4.97 metres grading 0.21% tin and 130 parts per million tantalum.
Viljoen said the company’s decision to expand its drilling footprint to better define the geological system and assess its economic potential was being validated by the latest results.
“Having strategically expanded our drilling footprint to fast-track the definition of the geological system’s true boundaries and economic value, these results further endorse our course of action,” he said.
He added that the presence of significant tin and tantalum mineralisation provided an attractive multi-commodity dimension to the project.
The company has now completed the expanded Stage 1 drilling programme, comprising 143 drill holes and approximately 16,500 metres of oriented diamond core. The programme was increased by 18% from its original scope and was completed in May 2026.
According to Andrada, Lithium Ridge is rapidly emerging as one of the most promising assets within its critical minerals portfolio. The project forms part of the company’s strategy to diversify beyond tin production and strengthen Namibia’s role in the global supply of minerals required for the energy transition.
Samples from the drilling programme were analysed by independent laboratories, with spodumene identified as the primary lithium-bearing mineral. The company said logging, sampling and analytical work remains ongoing as it advances the project towards resource definition and economic assessment.
“The additional presence of significant associated tin and tantalum mineralisation adds a highly attractive multi-commodity dimension to the potential project’s economic profile. Lithium Ridge is rapidly establishing itself as a standout project within Andrada’s critical minerals portfolio in Namibia,” Viljoen said.
