This announcement has been authorised for release by the Company Secretary of RareX Limited. RareX is a critical minerals company specialising in rare earths and niobium in hard rock carbonatites. The exploration focus of the business is on the new Khaleesi Project in the East Yilgarn which is a district-scale, elevated-niobium, alkaline intrusive complex - a breeding ground for mineralised carbonatites. Data from Tier-1 exploration programs with elevated niobium values suggests a highly fertile system. The Company’s engineering and commercial focus is on offtake and approvals at the mid-study-level, Cummins Range Project (+$330M NPV8 post-tax*) - a carbonatite hosted rare earths and phosphate project, containing magnet grade rare earths and battery grade phosphates and technically Australia’s largest undeveloped rare earths project. RareX have been curating a portfolio of carbonatite related prospects within which the newly acquired Khaleesi Project represents the exploration flagship. RareX will continue to develop and optimise its portfolio. RareX maintains material investments in Kincora Copper (ASX:KCC), Cosmos Exploration (ASX:C1X) and Canada Rare Earth Corporation (LL.V).
