Andrada Mining Limited has announced high-grade lithium drill results from the first phase of diamond drilling at its Lithium Ridge project in Namibia, confirming strong mineral continuity, depth extension and significant polymetallic potential.
The AIM-listed company said the initial results demonstrate lithium mineralisation from surface to depths of up to 160 metres, alongside notable tin and tantalum intersections.
Selected high-grade lithium intercepts include 9.63 metres at 2.12% lithium oxide (Li₂O) in drill hole LRD003, including a higher-grade section of 5.74 metres at 3.02% Li₂O. Drill hole LRD010 returned 24.44 metres at 1.38% Li₂O, while LRD011 intersected 16.81 metres at 1.51% Li₂O. Lithium mineralisation was intersected in most of the reported drill holes.
Chief Executive Officer Anthony Viljoen said the results reinforced confidence in the project’s potential.
“We are extremely pleased to announce these exceptional drill results from Lithium Ridge, which validate our confidence in this asset as a potential world-class lithium discovery. These drill results build on the recent high-grade grab sample results and show the continuity of lithium mineralisation at depth,” Viljoen said.
In addition to lithium, the drilling programme also identified notable tin and tantalum mineralisation, which Andrada said could enhance the project’s overall economics. Highlights include 2.57 metres grading 1.98% tin and 227 parts per million (ppm) tantalum in hole LRD001, and 1.33% tin with 247 ppm tantalum in hole LRD011.
The results form part of the Stage 1 exploration programme, which comprises approximately 14,000 metres of diamond drilling across 120 planned drill holes. Drilling began in August 2025, with the announced results covering the first 15 holes, representing 1,328 metres of drilling.
Viljoen said the high-grade intersections, with results reaching up to 3.02% Li₂O, demonstrate the scale and quality of mineralisation across the project area.
“These results not only confirm the continuity of lithium mineralisation from surface but also showcase substantial polymetallic potential, with meaningful tin and tantalum credits that could enhance project economics. Lithium Ridge represents an early-entry opportunity for Andrada into Africa’s emerging lithium sector, supported by our partnership with global leader SQM,” he said.
Andrada said drilling is progressing on schedule, with further updates expected as additional results are received. The company views Lithium Ridge as an early-entry opportunity into Africa’s growing lithium sector, supported by its partnership with SQM.
Lithium Ridge is being advanced in partnership with global chemicals group Sociedad Química y Minera de Chile (SQM), which may earn a 30% interest in the project under an existing earn-in agreement.
