Andrada Mining Reports Second Batch of Drill Results at Lithium Ridge

• Drill hole LRD031 returned 21.33 metres at 1.24% Li2O from 146.18 metres, including 7.20 metres at 1.99% Li2O
• Drill hole LRD025 intersected 16.24 metres at 1.04% Li2O from 0.87 metres depth, including 8.86 metres at 1.63% Li2O
• Tin and tantalum mineralisation confirmed in all reported drill holes
• Stage 1 drill programme expanded by approximately 18% to 16,500 metres and extended by three months
• Results reported under an earn-in agreement with SQM Australia (Pty) Ltd, a subsidiary of Sociedad Quimica y Minera de Chile SA

Andrada Mining Limited (AIM: ATM, OTCQB: ATMTF) is a Namibia-based tin producer with a portfolio of critical minerals mining and exploration assets. The company is scaling production across tin, lithium, tantalum, tungsten and copper. Andrada's stated strategy centres on unlocking Namibia's mineral resources through strategic partnerships, with the aim of supplying critical raw materials used in electric vehicles, solar panels and wind turbines.

Second Batch of High-Grade Lithium Drilling Results at Lithium Ridge

The second batch of results covers seven additional diamond drill holes at Lithium Ridge, a lithium exploration project in Namibia. Diamond drilling extracts a cylindrical core of rock from the ground, which is then analysed for metal content at different depths. All reported intersections represent apparent widths, meaning actual true thicknesses may differ depending on the angle of the ore body relative to the drill direction.

Drill hole LRD031 produced the highest-grade result of this batch, intersecting 21.33 metres at 1.24% Li2O (lithium oxide) from 146.18 metres depth, including a sub-interval of 7.20 metres at 1.99% Li2O. Drill hole LRD025 returned 16.24 metres at 1.04% Li2O beginning at 0.87 metres below surface, including 8.86 metres at 1.63% Li2O. Drill holes LRD022 and LRD017 also returned grades above 1.0% Li2O, at 1.38% and 1.50% respectively.

Across the seven holes, the company reports that high-grade lithium mineralisation was confirmed consistently from surface to depth. Spodumene, a lithium-bearing mineral, was visually identified as the primary carrier of lithium by the geological team on site.

Polymetallic Upside and Pegmatite System Continuity

In addition to lithium, tin and tantalum were confirmed in all reported holes. The company notes that the presence of these minerals is consistent with fertile lithium-bearing pegmatites (coarse-grained igneous rocks that host lithium) and may provide potential by-product value. No quantified economic contribution from tin or tantalum has been stated at this stage.

The mineralisation at Lithium Ridge spans multiple drill holes across the licence area, with results recorded from near surface down to depths exceeding 180 metres in some holes. The company reports that these results strengthen its understanding of the scale and continuity of the mineralised pegmatite system.

Chief Executive Officer Anthony Viljoen stated: 

"These results continue to strengthen our understanding of Lithium Ridge's pegmatite system, demonstrating consistent mineralisation across multiple drill holes. The combination of scale and grade emerging at this stage is particularly compelling."

Expanded Stage 1 Drill Programme Under SQM Earn-In Agreement

The drilling programme at Lithium Ridge is being conducted under a Stage 1 earn-in agreement with SQM Australia (Pty) Ltd, a subsidiary of Sociedad Quimica y Minera de Chile SA. An earn-in agreement allows a partner to acquire an interest in a project by funding an agreed exploration programme over a set period.

Following the results received to date, the Stage 1 programme has been expanded to approximately 16,500 metres of orientated diamond core drilling, an increase of around 18% from the original scope. The programme has also been extended by three months to further define the depth and lateral extent of the mineralised pegmatites identified at surface.

Chief Executive Officer Anthony Viljoen added: 

"On the back of these strong results, we have expanded the drilling programme to more fully test the extent of the system and to deepen our understanding of its full value potential, with the objective of accelerating overall project development."

Outlook

With the expanded programme now underway, Andrada intends to use the additional drilling to more fully define the scale and continuity of the Lithium Ridge system. The company has committed to providing regular updates as significant results are received and milestones are achieved. Technical data has been reviewed and approved by Professor Laurence Robb, a non-executive director of Andrada with over 30 years of exploration and economic geology experience, who serves as the Competent Person for this programme.
