## Minestarters Atlas summary

Cannindah Resources reported successful coarse particle flotation testwork at Mt Cannindah, achieving 94% copper and 92% silver recovery at a 450µm grind. These results, alongside conventional flotation confirming saleable concentrate, will inform an upcoming mineral resource update.

Reasoning: The results demonstrate high copper and silver recoveries using a coarse particle flotation method, which offers significant potential for reducing OPEX and CAPEX via lower energy and smaller plant requirements.

- Positive factor: High copper recovery \(94%\) at a significantly coarser grind size \(450µm\)

- Positive factor: Coarse flotation potentially reduces energy requirements and plant footprint

- Positive factor: Conventional flotation confirmed saleable concentrate with low penalty elements

- Positive factor: High mass rejection \(82%\) improves throughput potential

- Negative factor: Gold recovery results remain variable and difficult to represent

## How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
