Key Metallurgical Developments
Recent testwork confirmed a 93.6% recovery of feed antimony through flotation, with an 88.2% antimony extraction rate achieved during leaching. These results strengthen earlier findings and demonstrate the project’s ability to produce:
- A copper-silver concentrate with low arsenic impurities, improving its commercial value.
- A high-purity antimony product, further positioning Bulla Park as a strategic source of critical minerals.
The ability to generate multiple high-value product streams enhances the project’s economic potential and aligns with the growing demand for critical minerals used in battery technologies, renewable energy, and industrial applications.
Core Resources’ Role in Process Optimisation
Core continues to provide metallurgical testing and process optimisation services for the Bulla Park Project, helping refine flotation and leaching conditions to maximise metal recoveries. The latest testwork builds on previous results, offering further validation of the processing strategy.
In addition to laboratory testing, Core’s team supports process optimisation by analysing potential flowsheet improvements, impurity removal strategies and hydrometallurgical processing refinements to enhance the overall efficiency of the project.
Funding and Next Steps
To support ongoing project development, West Cobar Metals has secured $450,000 in capital to progress metallurgical studies, advance site work and explore additional opportunities, including a newly announced gold project.
Managing Director Matt Szwedzicki highlighted that the latest leach test successfully demonstrated the feasibility of efficiently separating antimony from copper concentrate using standard processing techniques. These positive results support further evaluation of processing pathways that could enhance overall recoveries.
Future Outlook
With strong metallurgical recoveries and a refined processing strategy, West Cobar Metals is progressing towards the next phase of development at Bulla Park. Ongoing collaboration with Core ensures that metallurgical solutions are tailored to achieve optimal metal recovery and processing efficiency.
