## Minestarters Atlas summary

Astral Resources has more than doubled its gold resource at the Spargoville project in Western Australia, with contained gold increasing 102% to 281,000 ounces. The update, conducted by Cube Consulting, uses a higher gold price assumption of A$4,500/oz and a 0.40g/t cut-off to expand the resource to 8.5 million tonnes at 1.0g/t gold.

Reasoning: Significant resource expansion \(102% increase in contained gold\) at Spargoville via re-estimation under updated economic assumptions.

- Positive factor: Contained gold increased 102%

- Positive factor: Resource expansion driven by updated gold price assumptions

- Positive factor: Re-optimised using DFS-aligned parameters

- Negative factor: Growth driven by higher gold price assumption rather than new geological discovery

- Negative factor: Further metallurgical testing recommended to increase confidence

Facts used in scoring: 4

## 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.
