Highlights
- Axel REE reports high-grade gallium mineralisation at the Caladão rare earths project.
- Gallium is primarily concentrated near-surface, enhancing economic potential alongside rare earths.
- Significant drilling results highlight thick, high-grade mineralised zones across key targets.
Axel REE has reported the discovery of significant gallium mineralisation at its flagship Caladão rare earths project in Brazil. The findings are based on auger and diamond drill samples from Phase One drilling, revealing promising potential across targeted zones.
The project, located in Area A, has seen over two hundred drill holes completed, spanning more than three thousand metres. These efforts highlight the potential for Caladão to evolve into a globally significant rare earths deposit.
Gallium Mineralisation Findings
The review indicates that gallium tends to occur in the near-surface sections of the weathering profile, particularly in aluminium-rich portions of the regolith. However, high-grade gallium has also been observed across thicker mineralised zones, indicating broader economic potential.
Key results include:
- Six metres at seventy-one grams per tonne gallium oxide starting from four metres, including one metre at one hundred twenty-four grams per tonne.
- Fourteen metres at seventy-seven grams per tonne gallium oxide starting from the surface, including seven metres at eighty-three grams per tonne.
- Six metres at seventy-one grams per tonne gallium oxide from the surface.
Rare Earths Complement Gallium
Axel REE’s managing director Dr Fernando Tallarico highlighted the synergies between gallium and the clay-hosted rare earth mineralisation at Caladão. The rare earths have been identified deeper in the regolith profile, whereas gallium is concentrated in shallower portions, previously considered overburden. This dual discovery positions gallium as a potentially valuable by-product alongside rare earths.
According to Dr Tallarico, the ability to recover gallium during rare earth extraction could present notable economic benefits as the deposit is further evaluated and developed.
Consistent Rare Earth Results
Earlier assays from the Phase One campaign demonstrated consistently high-grade total rare earth oxide (TREO) and magnet rare earth oxide (MREO) values. These results came from a thirty square kilometre zone in Area A, representing a small fraction of the total acreage. Standout figures include a record high of over twenty-eight thousand parts per million TREO and up to seven thousand parts per million MREO.
Axel REE plans to continue its comprehensive review as more assay results return from the current Phase One drilling. These developments strengthen the project's standing as a significant emerging resource in the global rare earths and critical minerals landscape.
