Ionic Adsorption Clays
The magnet metals behind motion.
Rare earths make modern permanent magnets possible — and four of them, neodymium, praseodymium, dysprosium and terbium, are what drive the motors in electric vehicles, robotics, medical devices and wind turbines. At Lake Chilwa, Chilwa has identified rare earths across the suite from two distinct sources: the alkaline intrusive system at Mpyupyu, and the ionic adsorption clays that sit beneath the company's mineral sands deposits. Combined with the rare-earth-bearing monazite within the HMS deposits, the project offers multiple, complementary pathways to the same critical supply.
(June 2026- Exploration results to date; rare earth grades are reported as part of ongoing drilling, not yet a defined Mineral Resource.)
