Mount Ridley Mines Limited (ASX: MRD) has announced a significant expansion of its tenure at the Mount Ridley Gallium and Rare Earth Project, located north of Esperance, Western Australia (Figure 1). The new Exploration Licences now consolidate the entire Grass Patch Complex — a distinctive geological domain marked by gravity and magnetic highs, interpreted to be associated with mafic intrusions, and recognised as a primary source of gallium and heavy rare earth enrichment.

Mount Ridley Mines Limited (ASX: MRD) has declared a maiden Inferred Gallium Mineral Resource Estimate (JORC 2012) of 838.7Mt @ 29.3 ppm Ga (39.5 ppm Ga₂O₃) at a 25 ppm Ga cut-off across three blocks at the Mt Ridley Project, ~55 km NE of Esperance, WA (Figure 1). Mineralisation is shallow, flat-lying and clay/saprolite-hosted, with strong associations to HREE and scandium.
