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.
