Aldoro Resources Confirms Thick High-Grade REE and Niobium Zones at Kameelburg

Exceptional Intersections Reinforce Kameelburg’s Multi-Commodity Potential

Aldoro Resources Ltd (ASX:ARN) has unveiled two major drill hole results from its flagship Kameelburg REE-Strontium-Niobium Project in Namibia, delivering some of the thickest and highest-grade mineralised intercepts seen to date in the Phase II drilling programme. Diamond drill hole DD008G returned a broad 318.3-metre composite intercept grading 1.51% total rare earth oxides (TREO), 4.90% strontium carbonate (SrCO₃), and 0.21% niobium pentoxide (Nb₂O₅), marking it as one of the most robust intersections drilled so far. Meanwhile, DD005D confirmed a near-surface high-grade REE zone of 136.3 metres at 1.97% TREO and 5.21% SrCO₃, alongside deep niobium mineralisation extending over 210 metres at 0.40% Nb₂O₅, reinforcing the vertical continuity of the deposit.

DD008G: Three-Dimensional Confidence in Eastern Resource Block

Drilled from the DD008 pad to a depth of 573.5 metres, DD008G was designed to intersect mineralisation perpendicular to the previously reported DD008D hole, providing vital three-dimensional geological constraints. The result exceeded expectations, with the broad mineralised envelope showing consistent grades over an impressive thickness. Notably, the strontium grade of 4.90% SrCO₃ carries independent economic significance, roughly equating to the value of 1% TREO at current commodity prices, thereby enhancing the combined value intensity of the intercept.

The hole also intersected a focused high-grade REE-strontium pod of 2 metres at 3.30% TREO and 9.13% SrCO₃ within the broader niobium-bearing envelope. This supports the concentric zonation model of mineralisation that has been validated across multiple drill directions at Kameelburg. Together with DD008D, these orthogonal holes bolster confidence in the eastern domain’s resource estimate ahead of the upcoming Phase II Mineral Resource Estimate (MRE).

DD005D: Surface REE and Deep Niobium Continuity at Southern Margin

DD005D, drilled to 604.4 metres from the DD005 pad, confirmed the persistence of high-grade REE mineralisation from surface, with 136.3 metres at 1.97% TREO and 5.21% SrCO₃. This near-surface zone aligns with the rich sovite core intersected consistently in central pad drill holes, extending the known strike of mineralisation into the south-southwestern sector.

Crucially, DD005D also intersected significant niobium mineralisation at depth. A 52-metre interval at 0.24% Nb₂O₅ in the Upper Layer margin is slightly above the average of other Phase II margin holes, while a substantial 210.8-metre interval at 0.40% Nb₂O₅ in the Lower Layer confirms deep niobium continuity. High-grade sub-zones within this interval include 47 metres at 0.51% Nb₂O₅ and 14 metres at 0.55% Nb₂O₅, demonstrating the vertical extent and tenor of niobium mineralisation in the southern sector.

Phase II Drilling Complete, MRE Update Imminent

The Phase II diamond drilling campaign has now concluded with 15 holes totaling 7,190 metres. Assay results are available for 12 holes, including the key DD008G and DD005D, with three remaining assays awaited. The comprehensive multi-directional drilling at both DD008 and DD005 pads provides robust geological and grade continuity data, critical for a confident resource update.

Aldoro anticipates releasing an updated Mineral Resource Estimate shortly, which is expected to capture the full scale and multi-commodity nature of the Kameelburg system. The three-dimensional drilling coverage, especially the perpendicular holes at DD008, significantly enhances the geological model’s confidence, while the confirmation of deep niobium zones at DD005 supports the deposit’s vertical extent.

The inclusion of strontium carbonate as a valuable secondary commodity alongside rare earth elements and niobium further underpins the project’s economic potential. The company’s metallurgical advancements, including high recovery rates for rare earths and strontium, complement these drilling results, suggesting a potentially lower-cost development pathway.

Geological and Sampling Rigor Supports Results

The drilling and sampling programme adhered to industry best practices, with triple tube diamond drilling and high core recovery rates exceeding 95% in mineralised zones. Samples were meticulously cut, prepared, and assayed using fusion techniques and ICP methods at accredited laboratories, supported by a rigorous QAQC programme including certified reference materials and blanks.

The mineralisation style at Kameelburg is carbonate-hosted REE and niobium associated with magnetite, similar to the Niobec Sant Honore deposit in Canada. The deposit’s geological setting within the Cretaceous Kameelburg Carbonatite plug and associated dykes in Namibia’s Damara Orogenic Belt provides a compelling framework for continued exploration and resource development.
