Minestarters Atlas analysis
Summary
Cannindah Resources has reported highly encouraging initial metallurgical results using NovaCell™ Coarse Particle Flotation at the Mt Cannindah Project. The technology achieved 94% Cu and 92% Ag recoveries at a coarse P80 of 450μm while rejecting 82% of the material, suggesting potential for significantly reduced energy and processing costs.
Reasoning: Strong initial metallurgical results using NovaCell technology demonstrate high copper and silver recoveries at a coarse grind, offering significant potential for lower-cost processing.
Positive factors
- High copper and silver recoveries using coarse particle flotation
- Significant mass rejection (82%) potentially reducing downstream costs
- Coarser grind size (P80 450μm) offers energy and throughput advantages
- Conventional flotation confirms saleable concentrate with low penalties
Negative factors
- Gold recovery is variable and lower in NovaCell tests compared to conventional
- Gold assaying issues noted due to small concentrate masses for fire assay
Facts used in scoring: 4
