Slide 9: Downunder Project | Irajuba Prospect
Downunder Project | Irajuba Prospect • The Irajuba Prospect is defined by major structurally controlled zones of REE anomalies • First-pass, shallow auger drilling in 2024 confirmed an ore-grade intersection in one of the 10 holes • Peak assay values over a metre of 4,346 ppm TREO with 1,513 ppm Nd2
Slide 10: Irajuba Prospect | Drilling
Irajuba Prospect | Drilling • Profile drilling depth based on Sulista REE project findings: 10m is too shallow for Irajuba, GMN is drilling deeper after initial results received • Very high proportion of Magnet REE – the valuable REE elements, to 58% MREO/TREO-Ce2O3 (1 metre interval in top of miner
