METEORIC RESOURCES (ASX:MEI) – Caldeira rare earths project

Did someone say “world leading magnet rare earth project?” Argonaut’s George Ross said just that about Caldeira’s potential.
The Brazilian property contains one of the highest grade clay rare earths resources in the world, making it in Argonaut’s estimation a global standout.
Only the lack of a scoping study keeps the $450 million capped Meteoric from being in the main list. That’s due early next year through Ausenco.
Caldeira boasts 409Mt at 0.26% total rare earth oxides, including a high grade component of 72Mt at 0.46% TREO, with just 20% of the property drilled so far.
Around 24% of the rare earths metals are magnet rare earths like praseodymium and neodymium. Those magnets are used in electric vehicle motors and wind turbines along with defence applications and more, making them critical for future facing energy technology.
The big test of the deposit will be its leachability in weak acids.
The benefit of “ionic” clay rare earths is they can be mined without blasting and processed through leaching at ambient temperatures, meaning energy intensive and environmentally sensitive processes like cracking and flotation used to process hard rock deposits like Lynas’ Mt Weld mine can be bypassed.
But not all clay rare earth deposits share those qualities, and some require more aggressive leach methods to liberate the metals from the ore.
“Ongoing metallurgical test work programs have achieved an average leachability of 70% from oxidised clays (grade range of 0.14-1.0% TREO) utilising an ammonium sulphate wash at pH 4.0,” Ross said.
