Slide 3: Gallium Mineralogy Breakthrough and Extraction Potential
GALLIUM MINERALOGY BREAKTHROUGH AND EXTRACTION POTENTIAL For personal use only • Gallium in Sericite: Approximately 90% of the total gallium is hosted in sericite, a type of muscovite, making it the primary target for concentration and extraction • Hydrothermal Alteration: Gallium is enriched in ser
Slide 4: Sericite as Primary Host
SERICITE AS PRIMARY HOST Extraction Advantages For personal use only Gallium presence in a single mineral • Simplifies extraction • Enhancing potential recovery from deposits • Sericite’s coarse-grained rock nature and amenability to flotation will favor traditional mineral processing for extraction
Slide 5: New Domestic US Supply Potential
NEW DOMESTIC US SUPPLY POTENTIAL For personal use only Advancement in Gallium Understanding Unlocking the full potential of Golconda begins with thorough mineralogy and metallurgical workflows that pave the way for its commercialisation. Our partners SGS Lakefield, are providing significant support
Slide 6: Highlights from Phase 2 RC Drilling and Significant Gallium Intercepts
