Gallium Recovery Challenges Emerge as G50 Begins Metallurgical Testing at Golconda
G50 Corp has engaged SGS Canada to initiate comprehensive metallurgical testing at its Golconda Project, aiming to refine gallium recovery methods and advance its strategic minerals portfolio.
- SGS Canada engaged for detailed metallurgical and mineralogy test work
- Focus on gallium and barium recovery from Golconda’s hydrothermal alteration zone
- No strong correlation found between gallium and copper or zinc; gallium correlates with barium
- Testing includes gravity separation and flotation methods
- Part of ongoing technical studies to validate Golconda’s strategic mineral potential
Strategic Partnership with SGS Canada
G50 Corp Limited (ASX: G50) has taken a decisive step forward in its Golconda Project in Arizona by engaging SGS Canada Inc. to conduct advanced mineralogy and metallurgical test work. This collaboration marks a significant progression from the initial XRD analyses performed in early 2024, aiming to deepen the understanding of gallium mineralisation and its amenability to recovery through conventional processing techniques.
Refining the Geological Model
Following the discovery of a high-grade gallium halo within a broad zone of hydrothermal alteration, veining, and brecciation, G50 has updated its geological model. Contrary to initial expectations, gallium does not show strong correlations with copper or zinc, minerals typically associated with chalcopyrite and sphalerite. Instead, gallium is closely linked to barium within argillized rock, a finding that could influence the recovery strategy and processing methods.
Testing Focus and Methodology
The upcoming metallurgical test work will evaluate the feasibility of recovering gallium and barium using gravity separation and flotation, two conventional mineral processing techniques. SGS Canada’s extensive global network and expertise in critical and strategic minerals, especially those vital for electromobility and energy storage, position them as an ideal partner to unlock the value of Golconda’s mineralisation.
Market and Technical Implications
Gallium is a critical mineral with growing demand driven by its applications in semiconductors, LEDs, and renewable energy technologies. G50’s Managing Director, Mark Wallace, highlighted the importance of this metallurgical testing phase, noting the strong interest from end customers and investors. The results could significantly enhance the project’s attractiveness by providing clarity on processing pathways and potential recoveries.
Next Steps for G50 Corp
As metallurgical testing progresses, G50 will integrate findings into its ongoing technical studies, refining both the geological model and economic assessments. This phase is critical to advancing Golconda from exploration towards development, potentially positioning G50 as a key player in the strategic minerals sector in the southwestern United States.
Bottom Line?
G50’s metallurgical testing at Golconda could redefine gallium recovery prospects, setting the stage for strategic growth.
Questions in the middle?
- What specific recovery rates for gallium and barium will SGS Canada’s testing reveal?
- How might the unexpected gallium-barium correlation influence processing costs and project economics?
- What timeline can investors expect for results and subsequent development milestones?
