## Minestarters Atlas summary

Collective Mining reported robust metallurgical test results for the Apollo system, featuring gold recoveries of 95% and silver recoveries of 92% on a master composite. The results also highlighted strong tungsten recovery \(up to 74%\) and significant gold amenability to gravity concentration, supporting the use of conventional processing methods.

Reasoning: The metallurgical results demonstrate high recoveries for all primary metals using standard, low-complexity processing routes, significantly de-risking the project's economic potential.

- Positive factor: High gold recovery \(95%\) on master composite

- Positive factor: Strong gravity response for gold \(up to 66% recovery\)

- Positive factor: High tungsten recovery \(up to 74%\) with high purity concentrate

- Positive factor: Conventional processing methods \(gravity, flotation, cyanidation\) are effective

- Positive factor: QA/QC disclosed with accredited lab \(ALS\) and QP sign-off

Facts used in scoring: 5

## Classification and evidence

**High Recovery**

Polarity: positive

Definition: Recovery at or above the exceptional band for the commodity and processing route.

Why it applies: Gold recovery of 95% on master composite and 96% on Ramp Zone material exceeds exceptional thresholds.

## 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.
