Asian Battery Metals Delivers Outstanding Metallurgical Results at Mongolian Copper-Nickel Discovery
Asian Battery Metals (ASX: AZ9) has delivered highly encouraging metallurgical test results from its flagship Oval Cu-Ni-PGE discovery in Mongolia, confirming excellent payable copper recoveries of 89-95% using a simple flotation process. This technical milestone significantly enhances the project's economic potential and development pathway.
The test work, conducted by ALS Metallurgy in Perth, successfully demonstrated that Oval's copper mineralisation can be efficiently recovered using a conventional flotation circuit – a crucial validation for future processing operations.
Managing Director Gan-Ochir Zunduisuren highlighted the importance of these findings: "These early results are highly encouraging, confirming that copper from Oval can be recovered at very high levels using a simple flotation process. This gives us confidence that Oval can generate a clean, marketable copper concentrate."
Key Metallurgical Achievements Unlock Processing Pathway
The metallurgical testing program has yielded several promising outcomes that strengthen Oval's development case:
- Excellent copper recoveries of 89-95% achieved in variability tests
- Simple two-product flotation flowsheet successfully established
- High-grade copper concentrate production confirmed (18.2-24.5% Cu)
- Marketable copper concentrate with favorable mineralogical characteristics
- Ongoing nickel and by-product optimization showing progressive improvements
The test program utilized three composite samples from drill hole OVD021, representing different mineralization styles at Oval: disseminated, net-textured, and massive sulphide material.
| Composite | Head Grade | Copper Concentrate | Nickel Concentrate | Total Recovery |
|---|---|---|---|---|
| 1 (Low Cu-Ni) | – | 18.2% Cu @ 89.3% recovery | 5.3% Ni @ 55.4% recovery | 92.0% Cu, 62.2% Ni |
| 2 (High Cu-Ni) | – | Test work ongoing | Test work ongoing | – |
| 3 (Medium Cu-Ni) | – | 24.5% Cu @ 94.9% recovery | 7.73% Ni @ 41.6% recovery | 97.3% Cu, 81.6% Ni |
Understanding Flotation: The Key to Oval's Mineral Recovery
What is flotation and why is it important?
Flotation is a widely-used mineral processing technique that separates valuable minerals from waste rock by exploiting differences in the surface properties of different minerals. In simple terms, it works by adding reagents that make specific minerals water-repellent (hydrophobic), allowing them to attach to air bubbles that rise to the surface for collection.
For investors, the successful demonstration of flotation at Oval is significant because:
- It confirms a conventional processing pathway without need for exotic or expensive technologies
- The high recovery rates (89-95% for copper) translate directly to better project economics
- The simple flowsheet suggests lower capital and operational costs for future development
- The ability to produce separate copper and nickel concentrates maximizes potential revenue streams
The successful metallurgical testing significantly de-risks the technical aspects of the project by proving that Oval's mineralisation can be processed using standard industry methods.
Strategic Advancement Across Multiple Project Fronts
Asian Battery Metals continues to advance the Oval discovery while simultaneously expanding its strategic footprint across southwest Mongolia:
- Phase 3 drilling successfully intersected broad zones of disseminated and massive sulphide mineralisation
- Step-out exploration ongoing to extend known mineralisation boundaries
- Scout drilling at MS1, MS2, and Quartz Hill targets to test regional potential
- Ongoing geophysical surveys to identify additional high-priority targets
- New ground positions secured at Bayan Sair and Maikhan Uul, expanding the company's district-scale footprint
This multi-pronged approach positions ABM to systematically build a comprehensive discovery model across one of Asia's most prospective copper-nickel belts.
Immediate Next Steps Focus on Technical Advancement
The company has outlined several near-term objectives to further advance the Asian Battery Metals copper project:
At Oval:
- Complete ongoing mineralogy studies on the three composite samples
- Recommence metallurgical testing with refinements based on mineralogy findings
- Release pending assay results from recent drilling within 2-3 weeks
- Interpret remaining FLEM and new DHEM data to refine targets and extend known mineralisation
At Regional Targets:
- Advance due diligence on the Maikhan Uul Cu-Au VMS project ahead of potential acquisition
- Complete new ground geophysics including MLEM at Copper Ridge and FLEM at Bayan Sair
- Identify additional regional targets to build a pipeline of exploration opportunities
