## Minestarters Atlas summary

Osisko Metals has filed a NI 43-101 Technical Report providing an updated Mineral Resource Estimate for the Copper Mountain deposit at the Gaspé Copper Project in Quebec. The 2026 MRE reports a total M&I resource of 1,834.2 Mt at 0.32% CuEq, supported by independent Qualified Persons.

Reasoning: The announcement of an updated 1.83 Bt M&I copper resource at the Gaspé Copper Project represents a significant scale update for the company, supported by a formal NI 43-101 technical report.

- Positive factor: Significant scale of M&I resource \(1.83 Bt\)

- Positive factor: High confidence in Measured and Indicated categories

- Positive factor: NI 43-101 compliant with independent QP sign-off

- Positive factor: Strategic location with existing infrastructure

- Negative factor: Large Inferred component \(238.8 Mt\)

- Negative factor: No economic study/evaluation produced yet

Facts used in scoring: 12

## Classification and evidence

**NI 43-101 Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard.

Why it applies: The report is explicitly stated to be prepared in accordance with NI 43-101 standards.

Evidence · text

> in accordance with National Instrument 43-101

**QP/CP Signed**

Polarity: positive

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: Three independent Qualified Persons \(Pierre-Luc Richard, François Le Moal, and Christian Laroche\) are named and responsible for the report.

Evidence · text

> All three qualified persons are "independent" of the Company

**Cut-off Disclosed**

Polarity: positive

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: The base-case cut-off grade of 0.16% CuEq is clearly stated.

Evidence · text

> reported at a base-case cut-off grade of 0.16% copper equivalent

**Inferred Resource**

Polarity: negative

Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: A significant portion of the resource is classified as Inferred.

Evidence · text

> The quantity and grade of reported inferred mineral resources are uncertain in nature

**Resource Update**

Polarity: neutral

Definition: Revised estimate for an existing resource — compare to prior to assess progress.

Why it applies: The source explicitly discloses a revised resource estimate

Evidence · text

> Updated Mineral Resource Estimate

## 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.
