Rumble Resources Ltd (ASX:RTR) Announces Metallurgical Success at Earaheedy
Metallurgical Highlights
Rumble Resources Ltd (ASX:RTR) has unveiled excellent metallurgical results from the Earaheedy Zn-Pb-Ag Project. The tests achieved recoveries of 79% zinc into a high-grade marketable bulk concentrate of 61% Zn+Pb, which is suitable for the Imperial Smelting Process (ISP). This success indicates the potential for significant energy savings in operational processing.
Innovative Processing Technology
The company employed innovative HydroFloat™ technology, which demonstrated the ability to reject over 30% of barren material. This early gangue rejection reduces the plant footprint and operational costs while enhancing tailings design and maintaining high recovery rates of 86% for zinc and lead. The test results signal a cost-efficient processing strategy that adapts well to varying feed grades.
Next Steps and Study Plans
Rumble plans to initiate an internal scoping study to evaluate the economic viability of producing a high-grade ISP concentrate. Results from this study are anticipated in 2025. Peter Harold, Managing Director and CEO of Rumble Resources, expressed confidence in the robust findings and their implications for the project’s economics and environmental sustainability. He stated, “The HydroFloat technology application further enhances the Earaheedy Project’s economic potential and reduces energy and water consumption.”
Market Position and Future Outlook
The Earaheedy Project, located 110km northeast of Wiluna in Western Australia, is ripe for potential development. With a significant maiden inferred Mineral Resource Estimate, Rumble aims to further explore and expand this world-class zinc discovery. The company also plans upcoming metallurgical studies and tests alongside marketing assessments to strategise off-take opportunities for the bulk concentrate.
