## Minestarters Atlas summary

Osisko Metals announced new drill results from its Gaspé Copper Project, highlighted by a significant intercept of 138 metres averaging 1.45% Cu, including 64.5 metres at 2.70% Cu, in the southern extension. These results confirm high-grade mineralization and extend the known resource, supporting an upcoming Mineral Resource Estimate update in early 2026.

Reasoning: The drill results from the Gaspé Copper Project include several high-grade copper intercepts, notably 64.5 metres averaging 2.70% Cu and 138.0 metres averaging 1.45% Cu, which extend mineralization in the southern extension and contribute to the upcoming resource estimate update.

- Positive factor: high-grade copper intercepts

- Positive factor: significant intercept lengths

- Positive factor: extension of mineralization

- Positive factor: infill drilling for resource upgrade

- Positive factor: true width disclosed

- Positive factor: QA/QC disclosed

- Positive factor: QP signed

- Positive factor: metal equivalent assumptions disclosed

Low confidence — this extraction should be reviewed alongside the original source.

## 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.
