Aldoro Resources’ latest drill results have returned 140 metres of high-grade niobium, including 15 metres at 0.8% Nb₂O₅ from 287 metres, 51 metres at 0.7% Nb₂O₅ from 348 metres, and 6 metres at 1.43% Nb₂O₅ from 393 metres to the end of the hole.
The results, from diamond drill hole DD005B, confirm the emergence of a significant, high-grade niobium zone at the western extent of the Kameelburg carbonatite in Namibia, extending the mineralised strike length by 400 meters to approximately 1,100 metres.
The new intercepts strengthen Aldoro’s geological model of vertical mineral zoning within the carbonatite, with rare earth element (REE) mineralisation concentrated in the upper layers and niobium enrichment increasing with depth.
DD005B returned 102.8 metres at 2.0% total rare earth oxides (TREO), 0.18% Nb₂O₅ and 203ppm molybdenum (Mo) in the upper layer, and 206.6 metres at 0.76% TREO, 0.43% Nb₂O₅ and 52ppm Mo in the lower, niobium-dominant zone.
DD008A, drilled in parallel, also confirmed broad mineralised zones, including 200.5 metres at 1.64% TREO and 0.177% Nb₂O₅ in the upper layer, and 75.6 metres at 0.61% TREO and 0.165% Nb₂O₅ in the lower zone.
“These results continue to demonstrate the continuity and scale of the Kameelburg deposit,” said Aldoro Chairperson Quinn Li. “The high-grade niobium intersected in DD005B validates our belief in a deeper, higher-grade zone to the west of the carbonatite—an area we’ll further test when our larger diamond rigs arrive in September.”
Aldoro’s Phase 1 diamond drilling campaign is nearing completion, with over 9,100 metres drilled to date across 24 holes. Final assays from DD005C, DD008B and DD008C are expected later in August and will be incorporated into an updated Mineral Resource Estimate.
The company is also preparing to mobilise a rig to the nearby Omuronga Carbonatite, where scout drilling and a magnetic survey are set to begin.
Omuronga is considered prospective for both heavy rare earth elements (HREEs) and niobium.
With minimal overburden, favourable logistics, and growing geological confidence, Kameelburg is shaping up as a globally significant niobium and REE project in one of Africa’s most mining-friendly jurisdictions.
Aldoro Resources has also released a maiden independent JORC Mineral Resource Estimate for the Kameelburg project, confirming a total of 279.9 million tonnes (Mt) at 2.45% TREO Eq¹ (1.16% TREO, 0.18% Nb, 177ppm Mo) at a 0.5% TREO cut-off. This includes a high-grade subset of 136.5 Mt at 2.93% TREO Eq¹ (1.58% TREO, 0.19% Nb, 295ppm Mo) at a 1.0% TREO cut-off, and 143.3 Mt at 0.23% Nb₂O₅ within the lower unit at a 0.1% Nb₂O₅ cut-off.
The resource, compiled by Lily Valley International Pty Ltd (LVI), currently reflects just over half of the Phase I drilling program, covering 5,543 metres from 11 diamond drill holes—about 60% of the completed 9,500-metre campaign.
A full Mineral Resource update incorporating the remaining data is expected in August.
The Kameelburg deposit remains open to the northwest and at depth, highlighting the potential for further resource expansion in Phase II drilling, which is scheduled to begin in Q4 2025.
Metallurgical testwork is also underway and expected to conclude later this month.
