## Minestarters Atlas summary

Osisko Metals announced a significant update to the Mineral Resource Estimate for its Gaspé Copper Project in Eastern Quebec. The updated MRE includes 1.83 billion tonnes of Measured and Indicated resources at 0.27% Cu \(0.32% CuEq\) and 239 million tonnes of Inferred resources at 0.41% Cu \(0.46% CuEq\). This represents a 119% increase in contained copper metal in the M&I categories over the previously reported Indicated Resource, establishing Gaspé Copper as one of the largest undeveloped copper-molybdenum deposits in North America. The company plans a 50,000-meter drill program to upgrade Inferred resources and expand the deposit.

Reasoning: The updated Mineral Resource Estimate for Gaspé Copper shows a significant increase in Measured and Indicated resources, with a 119% increase in contained copper metal over the previously reported Indicated Resource. This positions the project as one of North America's largest undeveloped copper-molybdenum deposits, supported by a detailed NI 43-101 compliant estimate and a planned drill program to further upgrade and expand resources.

- Positive factor: Tonnage Growth

- Positive factor: Contained Metal Growth

- Positive factor: Category Upgrade

- Positive factor: QP/CP Signed

- Positive factor: NI 43-101 Compliant

- Positive factor: Maiden Resource \(for the updated M&I scale\)

## 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.
