Axel REE (ASX:AXL) has expanded the scale of its flagship Caladão REE–Gallium Project in Minas Gerais, Brazil, with the delivery of a maiden JORC (2012) inferred mineral resource estimate for Area B, confirming the project as a district-scale critical minerals system.
The new Area B resource totals 339Mt at 1,075ppm total rare earth oxides and 36.6ppm gallium, using a 500ppm TREO cut-off, lifting the combined Area A and B resource to 572Mt at 1,506ppm TREO—a 145% increase—and 43Mt at 38ppm gallium, a 33% increase.
The updated resource spans approximately 151km2, representing only about 35% of the total Caladão tenure, and positions the project as one of the largest ionic clay-hosted rare earth projects in the Americas and one of the world’s largest discrete gallium deposits.
Mineralisation in Area B is distributed across the Marambaia, Tiger Creek and Woolrich deposits, providing multiple potential development fronts.
Metallurgical test work continues to underpin Axel's in situ recovery strategy, with magnesium sulphate leach testing at the Woolrich deposit achieving 464ppm soluble TREO, comparable to profitable Asian operations and confirming strong leachability of magnet rare earths, including NdPr and DyTb.
The company plans further leach testing, infill drilling and hydrological studies to support a soluble-REE focused resource update and advance scoping studies for modular in situ recovery operations targeted for 2026.
