On April 13, 2023, Ionic Rare Earths announced that it raised its stake by 60% in the Makuutu Rare Earths Project in Uganda by acquiring controlling ownership of Ugandan subsidiary Rwenzori Rare Metals Limited (RRM) which owns 100% of the Makuutu Rare Earths Project, following DFS and Ugandan Government approval.
The remaining stake is held by the South African registered Rare Earth Elements Africa Proprietary Limited (REEA) and by Ugandan Partners.
Makuutu is an ionic adsorption clay (IAC) deposit. IAC deposits contain rare earth elements (REE) ionically bonded to the clay rather than existing as primary minerals in the ore. IAC REE mineralisation can be summarised as REEs that are mainly adsorbed onto the surfaces of clay minerals in the form of hydrated ions or hydroxylhydrated ions. These REE deposits are hosted within the regolith (laterite profile).At Makuutu, the mineralisation is contained within the tropical lateritic weathering profile of a basin filled with sedimentary rocks including shales, mudstones and sandstones potentially derived from the surrounding granitic and mafic rocks. These rocks are considered the original source of the REE which were then accumulated in the sediments of the basin as the surrounding rocks have degraded. These sediments then form the protolith that was subjected to prolonged tropical weathering.The weathering developed a lateritic regolith with a surface indurated hardcap, followed downward by clay rich zones that grade down through saprolite and saprock to unweathered sediments. The thickness of the regolith is between 10 and 20 metres from surface.The REE mineralisation is concentrated in the weathered profile where it has dissolved from its primary mineral form, such as monazite and xenotime, then ionically bonded (adsorbed) or colloidally bonded on to fine particles of aluminosilicate clays (e.g., kaolinite, illite, smectite). The adsorbed and colloidal REE is the target for extraction and production of REO at Makuutu.At Makuutu the top of the mineralised zone is defined by a thin surficial soil/hardcap zone that averages 3 m in thickness (cover zone). The base of the mineralised zone is defined by the top of the saprock/fresh rock boundary which extends to an average vertical depth of 9.0 m (Clay zone).
