3 World Class Critical Mineral Assets Within Single Regolith Profile
Rarely does a single regolith profile host three independently defined, world class critical mineral assets. At the Grass Patch Complex, Heavy Rare Earths, Scandium, and Gallium are uniquely colocated, creating a strategically significant multi-element system with compelling potential for integrated development and extraction efficiencies.
A UNIQUE CONVERGENCE
Heavy Rare Earths, Scandium, and Gallium are independently defined yet spatially coincident at the Grass Patch Complex, enabling potential combined extraction efficiencies.
Heavy Rare Earths (HREE)
- JORC (2012) compliant inferred MRE of 122.5Mt @ 889ppm TREO
- 108,954t contained REO metal
- 41% HREO composition
- 46,810t contained HREO metal
- Key elements: Dy, Tb, Y
Scandium (SC)
- JORC (2012) compliant inferred MRE of 367.98Mt @ 57.2ppm Sc (87.9ppm Sc2O3)
- 18,555t Scandium
- 28,920t Scandium oxide
- One of the largest scandium resources globally
Gallium (GA)
- JORC (2012) compliant inferred MRE of 838.7Mt @ 28.3ppm Gallium
- 24,584t contained Gallium
- Strategically significant given Chinese export restrictions
Mount Ridley’s Flagship Project
Mount Ridley Mines Limited (ASX:MRD) is advancing its Critical Mineral Projects across Western Australia. Its flagship Mount Ridley Project, located just 25 kilometres from the Port of Esperance, provides a strategic logistical advantage for future development, export, and downstream opportunities.
Complementing this is the Weld Range Project in the Mid-West region of Western Australia, covering an area of 52km². Together, these projects deliver strong exposure to clay-hosted rare earth systems and position Mount Ridley Mines as an emerging contributor to Australia’s expanding critical minerals sector.
