## Minestarters Atlas summary

Western Exploration has completed cyanide leach test work at the Gravel Creek project, reporting high recoveries for both gold and silver. The results were achieved across oxide, transition, and fresh rock domains using a standard mill route.

Reasoning: The cyanide leach test work achieved exceptional gold and silver recoveries across multiple ore domains using an established mill route, significantly de-risking the project's metallurgical profile.

- Positive factor: High gold recovery

- Positive factor: High silver recovery

- Positive factor: Established process route

- Positive factor: Multiple domains tested

Facts used in scoring: 6

## Classification and evidence

**Multi-Domain Tested**

Polarity: positive

Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed.

Why it applies: 3 distinct composites were tested

## Extracted facts

Stored fact records: 6. Some facts used in scoring do not have a stored record.

## Metallurgical Results (6)

## 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.
