Highlights

  • Aldoro Resources shares rose 4.55% to AUD 0.46 during morning trading on May 11, 2026, after the company released an updated Mineral Resource Estimate for its Kameelburg project in Namibia showing an Inferred Resource of 597.07 million tonnes at 2.49% TREO Equivalent, a 15% tonnage increase on the September 2025 estimate.
  • The company simultaneously declared a maiden Strontium Mineral Resource of 596.01 million tonnes at 2.17% Sr, which it described as confirming Kameelburg as the world's largest strontium resource — a strategically significant designation given that global strontium Supply is currently dominated by China and Iran.
  • Initial strontium leach testwork returned a 98.96% extraction rate in 120 minutes at ambient temperature, requiring no elevated temperature, pressure, or pre-concentration — results that significantly de-risk the metallurgical processing assumptions for the strontium by-product stream.

 

Aldoro Resources Limited (ASX:ARN) posted a 4.55% gain to AUD 0.46 in morning trading on May 11, 2026, extending the stock's twelve-month gain of 35.29% as the company released a landmark mineral resource update for its 85%-owned Kameelburg project in Namibia. The update combined a substantial uplift to the existing rare earth element resource with the declaration of a maiden strontium resource of global strategic significance. For a junior explorer with a Market Capitalisation in the tens of millions of Australian dollars, the scale and quality of the Kameelburg resource position it as one of the more notable critical minerals discoveries globally in recent years.

The company has been systematically drilling the Kameelburg carbonatite since 2024, and the Phase 2 drilling results — of which only five holes have been reported against a much larger program still in progress — have already driven a 15% tonnage increase at unchanged grade. The June 2026 release of final Phase 2 assays is expected to produce a further resource update, suggesting the current figures are unlikely to represent the peak of the Kameelburg resource envelope. The deposit remains open in all directions — along strike, down-dip, and at depth — providing a clear geological rationale for continued upside.

The REE Resource: Scale and Grade in Context

The updated Inferred Mineral Resource Estimate at Kameelburg, prepared by independent consultants Lily Valley International in accordance with the JORC Code (2012 Edition), stands at 597.07 million tonnes at 2.49% Total Rare Earth Oxide Equivalent at a 0.5% TREO cut-off grade. The TREO Equivalent calculation incorporates 1.19% TREO, 0.20% niobium pentoxide, and 205 parts per million molybdenum. The high-grade subset, reported at a 1.0% TREO cut-off, has grown to 312.65 million tonnes at 2.87% TREO Equivalent — a more than doubling of the high-grade tonnes since the September 2025 update, which is significant because the high-grade material is likely to define the early-year production and Cash Flow profile of any future Mining operation.

The rare earth profile at Kameelburg is characterised as neodymium-praseodymium rich, which is commercially the most valuable subset of the rare earth oxide market. NdPr oxides are the critical feedstock for permanent magnets used in electric vehicle motors, wind turbine generators, and a range of defence and consumer electronics applications. The niobium content adds a second Revenue stream with its own supply chain significance, as niobium is used primarily in high-strength steel alloys and superconducting applications, and global production is heavily concentrated in Brazil.

The Strontium Declaration: Strategic Supply Chain Implications

The maiden Strontium Mineral Resource of 596.01 million tonnes at 2.17% Sr, declared as a co-located by-product Credit within and inclusive of the TREO Resource, carries significant geopolitical and supply chain implications that extend well beyond the mining Economics alone. Strontium is used primarily in the production of ferrite permanent magnets, specialty glass — including faceplate glass for cathode ray display technology and radiation shielding applications — and a range of defence-related applications. Current global production is dominated by China and Iran, with limited supply from Western or aligned nations.

The positioning of Kameelburg as a potential source of strontium outside the China-Iran supply chain has strategic relevance for Western governments and industrial consumers seeking supply chain Diversification, particularly as critical minerals supply chains have become a significant policy focus in the United States, European Union, and Australia. The leach testwork results — 98.96% strontium extraction in 120 minutes at ambient temperature — are exceptionally strong. The absence of elevated temperature, pressure, or pre-concentration requirements substantially simplifies the processing flow sheet and improves the economics of strontium carbonate production as a by-product.

Infrastructure and Jurisdiction: A Rare Combination

Kameelburg is located in Namibia, which has earned a reputation as one of Africa's most mining-friendly and politically stable jurisdictions. The project's infrastructure position is unusually strong for a greenfield deposit of this scale: a bitumen highway passes within 300 metres, TransNamib heavy-haul freight rail is within two kilometres, 220-kilovolt Hydropower transmission infrastructure is within seven kilometres, and the deep-water Port of Walvis Bay is 355 kilometres to the southwest. This combination of proximate infrastructure significantly reduces the Capital intensity of any future project development relative to remote greenfield deposits that require substantial infrastructure construction.

A Multiproduct Platform with Four Revenue Streams

Aldoro has positioned Kameelburg as a multiproduct critical minerals platform with four distinct potential revenue streams: rare earth oxides with an NdPr-rich profile, niobium pentoxide, strontium carbonate as a by-product, and a potential magnetite-hosted iron by-product currently under metallurgical assessment. Each of these products targets structurally growing end markets where supply is either geographically concentrated or supply chain-constrained. The company's Phase 2 drilling program is ongoing, with the final resource update expected in June 2026. Exploration activities to define the full extent of the deposit continue, with Aldoro conducting geological mapping, surface sampling, and Geophysical surveys across the project tenure.

Conclusion

The Kameelburg Mineral Resource Estimate update positions Aldoro Resources as the holder of a globally significant critical minerals asset at a moment in history when supply chain diversification away from China and Iran has become a priority for governments and industrial consumers alike. The scale of the REE and strontium resources, the NdPr-rich grade profile, the exceptional strontium metallurgical results, the favourable Namibian jurisdiction, and the proximate world-class infrastructure create a combination that is rarely encountered in greenfield mineral exploration. While the path from resource declaration to production involves numerous technical, financing, and permitting steps, the May 11 share price move reflects the market's growing recognition of Kameelburg's strategic potential.
