Australian-listed Aldoro Resources Ltd has delivered another major drilling breakthrough at its Kameelburg rare earth, strontium, and niobium project in Namibia, with two new drill holes confirming broad, high-grade mineralisation from surface to depth across the carbonatite system.
The latest results came from drill holes DD008G and DD005D, both completed during the company’s Phase II drilling programme, which comprised 15 holes totalling 7,190 metres.
The strongest result came from DD008G, which returned 318.3 metres grading 1.51% total rare earth oxides (TREO), 4.90% strontium carbonate, 0.21% niobium pentoxide and 174 parts per million molybdenum using a 1% TREO cut-off.
The hole was drilled to a total depth of 573.5 metres from the eastern side of the Kameelburg carbonatite and is now regarded as one of the best holes drilled on the project to date.
Within the broader mineralised interval, Aldoro also intersected a higher-grade rare earth and strontium zone of two metres grading 3.30% TREO and 9.13% strontium carbonate between 427 metres and 429 metres depth.
The company said DD008G, together with previously reported hole DD008D drilled from the same pad but in a perpendicular direction, now provides strong three-dimensional confirmation that mineralisation remains continuous across the eastern resource block.
At the southern portion of the carbonatite, drill hole DD005D delivered another major rare earth and niobium intersection after being drilled to a total depth of 604.4 metres.
From the surface, the hole returned 136.3 metres grading 1.97% TREO and 5.21% strontium carbonate, confirming that high-grade rare earth mineralisation continues into the south-southwestern part of the system.
The hole also intersected a 52 metre niobium interval grading 0.24% niobium pentoxide within the upper layer of the carbonatite.
More significantly, DD005D intersected a deep niobium zone measuring 210.8 metres grading 0.40% niobium pentoxide below 282 metres depth.
That deeper niobium interval included 47 metres grading 0.51% niobium pentoxide between 363 metres and 410 metres and 14 metres grading 0.55% niobium pentoxide between 509 metres and 523 metres.
Aldoro said the results confirm that niobium mineralisation extends beyond 500 metres depth and remains continuous along the southern margin of the carbonatite system.
The company has now received assay results for 12 of the 15 Phase II drill holes, with results from DD008E, DD008F and DD013A still pending.
The DD005 drill pad alone has now produced four mineralised holes drilled in different directions. In comparison, the DD008 pad has produced two major mineralised holes drilled at right angles to each other, significantly strengthening geological confidence ahead of the updated mineral resource estimate.
Kameelburg is emerging as one of Namibia’s more significant critical minerals projects as global demand for rare earth elements and niobium used in electric vehicles, permanent magnets, renewable energy systems, and advanced industrial alloys continues to rise.
