Mount Ridley Mines Files Second Selectro Patent Following 92% Aluminum Recovery From Bauxite

Highlights

• Mount Ridley Mines filed a second provisional Selectro patent on October 15, 2026, expanding the technology from rare earths to industrial metals including aluminum and iron.
• Initial ALS laboratory tests on a one-kilogram bauxite sample achieved 91.9% aluminum and 96.7% iron extraction, with gallium recovery results still pending.
• Selectro reportedly operated below 100°C with over 90% silica retained in a pH-neutral residue, suggesting potential advantages over conventional Bayer refining.
• Gallium recovery could strengthen the strategic case given China's dominance of global gallium supply, but commercial feasibility remains unproven at scale.
• Investors should await complete metal balances, reagent economics, pilot-scale validation, and independent product qualification before drawing conclusions.
