Aldoro Resources (ASX: ARN) has announced a massive expansion of its Kameelburg project's Inferred Mineral Resource in Namibia.
This new resource totals 596.01 Mt at 2.17% Sr (at a 0.5% Sr cut-off), positioning Kameelburg as the world’s largest strontium resource outside of China and Iran.
Initial strontium leach test work has also shown promising results.
The company achieved 98.96% Sr extraction in 120 minutes at ambient temperature, indicating that elevated temperature or pressure, or pre-concentration, may not be required.
Strontium carbonate (strontianite) has been identified in broad zones alongside elevated TREO during previous drilling at Kameelburg.
Expanded REE and Niobium Resources
The updated JORC (2012) Inferred Mineral Resource for Kameelburg now stands at 597.07 Mt at 2.49% TREO-equivalent (at a 0.5% TREO cut-off).
This represents a 15% tonnage increase compared to the September 2025 Phase I update, maintaining an unchanged grade.
The high-grade subset of this resource has also expanded significantly to 312.65 Mt at 2.87% TREO-equivalent (at a 1.0% TREO cut-off), with high-grade tonnage more than doubling since September 2025.
These resource updates are based on 29 diamond drill holes, totalling 12,044 m.
Previous drilling, including results from DD003A in Phase II, also indicated high-grade niobium (Nb2O5) intercepts, such as 11m at 0.76% Nb2O5 from 102m.
This reinforces Kameelburg's potential as a multi-product critical minerals platform, with potential revenue streams including NdPr-rich rare earth oxides, Nb2O5, and Sr carbonate by-product.
Project Infrastructure and Growth Potential
The Kameelburg project benefits from excellent existing infrastructure in Namibia.
A C33 bitumen highway is located within 300 m, TransNamib rail within 2 km, and 220 kV hydropower within 7 km.
The deep-water Port of Walvis Bay is situated 355 km away, providing logistical advantages.
The company reports that the mineral resource remains open along strike, down-dip, and at depth in all directions, indicating further growth potential.
Phase II drilling is continuing, with the final Mineral Resource Estimate from this phase expected in June after the receipt of all remaining assays.
Funding and Development Context
Aldoro has secured funding to advance the Kameelburg project.
In a prior announcement, a $3.27 million underwriting agreement was secured for unlisted options expiring in September 2026.
These proceeds are earmarked for additional metallurgical drilling using the Smart 8 rig, further metallurgical test work including pilot tests for a Definitive Feasibility Study stage, and general working capital.
Additionally, the Namibian Ministry of Mines and Energy has approved the transfer of exploration permits EPL 7372, 7373, and 7895 to the Aldoro JV operating company, ensuring continuity of tenure for ongoing development work.
