## Minestarters Atlas summary

Osisko Metals has filed a NI 43-101 Technical Report for the Gaspé Copper Project in Quebec, featuring an updated 2026 Mineral Resource Estimate. The estimate includes 1,834.2 Mt of M&I and Inferred resources at 0.32% CuEq, supported by independent Qualified Persons.

Reasoning: The filing of a formal NI 43-101 Technical Report with an updated MRE provides high-confidence geological data for a large-scale copper project.

- Positive factor: Significant resource scale

- Positive factor: QP/CP signed

- Positive factor: NI 43-101 compliant

- Positive factor: Detailed CuEq assumptions disclosed

- Negative factor: Large Inferred component

Facts used in scoring: 15

## 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 a formal NI 43-101 Technical Report filed on SEDAR+.

Evidence · text

> Osisko Metals Files NI 43-101 Technical Report

**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 \(P.Geo and P.Eng\) 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 explicitly stated.

Evidence · text

> base-case cut-off grade of 0.16% copper equivalent \(" CuEq "\)

**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 in the Inferred category.

Evidence · text

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

## 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.
