• 98.96% strontium extraction achieved in HCl acid leach metallurgical test
• Head grade of 2.67% Sr (4.49% SrCO₃) representing exceptionally high-grade carbonatite-hosted strontium mineralisation
• Strontium extraction result is among the highest reported globally for any strontium-bearing ore system

Aldoro Resources Ltd has announced the results of an initial metallurgical testwork program on a composite ore sample from the Kameelburg Project in Namibia, achieving 98.96% strontium extraction in HCl acid leach metallurgical testing. The Kameelburg Project is a carbonatite-hosted critical minerals system hosting mineralisation in the ancylite mineral phase. The objective of the testwork was to evaluate the amenability of the Kameelburg ore to acid leaching as a potential strontium metal extraction pathway. The composite sample had a head grade of 2.67% strontium, representing exceptionally high-grade carbonatite-hosted strontium mineralisation. The 98.96% strontium extraction result was achieved at ambient temperature (21°C) and a modest acid concentration of 10% w/w HCl, without the need for elevated temperature, pressure, or pre-concentration. This result is among the highest reported globally for any strontium-bearing ore system under comparable conditions. The Kameelburg ore contains strontium in the ancylite phase, a strontium-REE carbonate mineral, which is readily dissolved in HCl under mild conditions, representing a significant metallurgical advantage over conventional celestite (strontium sulphate) ores. Strontium is classified as a Critical Raw Material by the European Union and India, with global supply heavily concentrated in a handful of producing nations, creating significant geopolitical supply risk. The global strontium market is projected to grow at a CAGR of 5-6% through 2033, driven by increasing demand from the defence, ceramics, and emerging advanced materials sectors.

The outstanding metallurgical results have accelerated an updated Mineral Resource Estimate (MRE) to incorporate strontium carbonate (SrCO₃) and iron content from Phase 1 drilling, with the aim of reflecting the significant value of SrCO₃ within the Project.
