en.Wedoany.com Reported - On June 5, Aldoro Resources Limited, listed on the Australian Securities Exchange, announced that its flagship Kameelburg Rare Earth and Strontium Project in Namibia achieved successful initial metallurgical test results, with a total rare earth element extraction rate of 72% and a strontium recovery rate exceeding 99%. Founded in 2017 and headquartered in Perth, Australia, Aldoro Resources is a company focused on the exploration and development of critical mineral resources. The company's project portfolio covers rare earth elements, nickel, niobium, lithium, rubidium, and base metals, with its flagship asset, the Kameelburg Project, located in the central Damara Orogenic Belt in northern Namibia. This is a carbonatite-type rare earth-niobium-strontium deposit, covering the Cretaceous-aged Kameelburg carbonatite plug.
Test results indicate that Kameelburg ore can be directly leached without pre-beneficiation. Compared to most rare earth projects globally, this characteristic is expected to simplify the processing flow. Chairman Liqun Li (also known as Quinn Li) stated that these preliminary metallurgical test results mark an important step in de-risking the Kameelburg Project and further establish the project as one of the world's most significant undeveloped rare earth and strontium deposits. Liqun Li has over 20 years of experience in the resources and development industry, with expertise in asset divestment and project financing. She was appointed as Non-Executive Chair in April 2024 and transitioned to Executive Chair in November of the same year.
The head grade of the blended ore sample was 1.28% total rare earth element content and 2.67% strontium content. At a hydrochloric acid concentration of 15%, a single leach achieved approximately 69% rare earth recovery; through cumulative leaching and re-leaching tests, the recovery rate increased to 72%. In all acid leach tests, strontium extraction rates exceeded 99%. Calcium extraction rates exceeded 94% in the initial leach test and achieved a cumulative recovery rate of over 99% after the re-leaching stage. Liqun Li noted that the exceptionally high strontium recovery rate highlights the "multi-product" nature of the Kameelburg Project. The project hosts the largest proven strontium resource globally, along with globally significant rare earth and niobium resources, with total resources exceeding 596 million tonnes. The Kameelburg Project's carbonatite intrusion has a diameter of approximately 1.4 kilometers, with an ore resource of 521 million tonnes and a total rare earth oxide equivalent grade of 2.49%. Recent drilling has also continued to intersect high-grade mineralization at depth and along the northeastern margin, further expanding the resource scale of the system.
Aldoro Resources plans to conduct the next phase of metallurgical test work, aiming to optimize extraction parameters, evaluate pre-concentration options, and determine a process flowsheet suitable for a preliminary economic study. The company is managed by experienced geologists, and Non-Executive Director Dr. Minlu Fu has previously participated in the development of super-large copper-gold deposits such as Ernest Henry in Australia.
