## Minestarters Atlas summary

Osisko Metals announced new drill results from its Gaspé Copper Project in Eastern Québec, featuring a record 1117.5-metre intercept averaging 0.25% Cu, 1.81 g/t Ag, and 0.022% Mo \(0.35% CuEq\). The program includes both infill drilling to upgrade resources and expansion drilling to extend mineralization, with an updated MRE planned for Q1 2026. The results confirm the project's potential as a large, undeveloped copper resource, supported by robust QA/QC and transparent reporting.

Reasoning: Osisko Metals has reported new drill results from its Gaspé Copper Project, highlighted by exceptionally long intercepts, including a record 1117.5 metres of continuous mineralization. While copper grades are moderate for a porphyry system, the sheer scale of mineralization, combined with a strategic infill and expansion drill program, indicates significant potential for resource growth and conversion. Strong QA/QC and transparent reporting further bolster confidence in these positive results.

- Positive factor: Exceptional intercept lengths, including a record 1117.5 metres, indicating significant bulk tonnage potential.

- Positive factor: Drilling confirms and extends mineralization within and outside the existing resource model, supporting future resource growth.

- Positive factor: Mixed drill program strategy targets both resource conversion \(infill\) and expansion, de-risking and growing the project.

- Positive factor: Comprehensive QA/QC procedures are disclosed, including certified lab analysis and Qualified Person sign-off, enhancing data credibility.

- Positive factor: Metal equivalent calculations are transparent with disclosed prices and recoveries, allowing for informed evaluation.

- Negative factor: Individual copper grades, while moderate, are generally below the 75th percentile for porphyry copper deposits, suggesting a bulk tonnage rather than high-grade profile.

- Negative factor: True widths are estimated as a general percentage rather than provided precisely for each intercept, which introduces a minor degree of uncertainty.

Reasoning: This infill intercept, with a moderate copper grade over a good width, contributes to the overall resource definition and continuity within the existing model, supporting the goal of upgrading resource categories.

- Positive factor: Strong continuity of 63.0 metres, contributing to resource definition.

- Positive factor: Infill drilling supports upgrading inferred resources.

- Positive factor: Moderate copper grade of 0.19% Cu \(0.20% CuEq\) is consistent with a bulk tonnage porphyry deposit.

- Positive factor: Good QA/QC and QP sign-off provide high confidence in the reported results.

- Negative factor: Copper grade is moderate for a porphyry system, falling between the 25th and 75th percentile of peer comparisons.

Reasoning: This significant intercept, combining infill and expansion, materially contributes to both the definition and potential growth of the resource, demonstrating good continuity of mineralization.

- Positive factor: Long intercept of 93.7 metres, indicating substantial continuous mineralization.

- Positive factor: Mixed infill and expansion nature contributes to both resource confidence and potential growth.

- Positive factor: Moderate copper grade of 0.25% Cu \(0.30% CuEq\) is consistent with a bulk tonnage porphyry deposit.

- Positive factor: Good QA/QC and QP sign-off provide high confidence in the reported results.

- Negative factor: Copper grade is moderate for a porphyry system, falling between the 25th and 75th percentile of peer comparisons.

Reasoning: This significant expansion intercept demonstrates the potential to extend mineralization deeper within the deposit, adding new ounces and contributing materially to the project's overall scale and future resource updates.

- Positive factor: Long intercept of 288.0 metres, extending mineralization to a vertical depth of 666 metres.

- Positive factor: Moderate copper grade of 0.19% Cu \(0.25% CuEq\) is consistent with a bulk tonnage porphyry deposit.

- Positive factor: Expansion drilling outside the current MRE model adds new potential resources.

- Positive factor: Good QA/QC and QP sign-off provide high confidence in the reported results.

- Negative factor: Copper grade is moderate for a porphyry system, falling between the 25th and 75th percentile of peer comparisons.

## 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.
