## Minestarters Atlas summary

Osisko Metals announced a significantly updated Mineral Resource Estimate for its Gaspé Copper Project in Eastern Quebec, reporting 1.83 billion tonnes at 0.27% Cu \(0.32% CuEq\) in Measured and Indicated categories, and an additional 239 million tonnes at 0.41% Cu \(0.46% CuEq\) in the Inferred category. This update 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 North America's largest undeveloped copper-molybdenum deposits. The company plans further drilling to upgrade Inferred resources and expand the deposit.

Reasoning: The updated MRE significantly increases Measured and Indicated copper metal content by 119%, converting previous Inferred resources and expanding the overall resource base. While the average grade has decreased due to a lower cut-off grade and the pit-constrained nature of the resource, the substantial increase in contained metal and resource confidence represents a major de-risking and scale-up for the project.

- Positive factor: Category Upgrade

- Positive factor: Tonnage Growth

- Positive factor: Contained Metal Growth

- Positive factor: QP/CP Signed

- Positive factor: NI 43-101 Compliant

- Positive factor: Cut-off Disclosed

- Negative factor: Grade Decline

- Negative factor: Cut-off Lowered

Facts used in scoring: 72

## Classification and evidence

**Category Upgrade**

Polarity: positive

Definition: Resource confidence improved — Inferred upgraded to Indicated, or Indicated to Measured. De-risking signal.

Why it applies: The 2025 drill program successfully converted and expanded the 2024 MRE to the Measured and Indicated resource categories.

Evidence · text

> The 2025 drill program successfully converted and expanded the 2024 MRE to the Measured and Indicated resource categories

**Tonnage Growth**

Polarity: positive

Definition: Significant tonnage increase \(≥15%\) vs prior estimate with grade maintained or improved.

Why it applies: The updated MRE reports 1.83 billion tonnes in M&I categories, representing a significant increase in the overall resource base.

Evidence · text

> 1,834 million tonnes averaging 0.27% Cu \(0.32% CuEq \) of Measured and Indicated categories \(M&I\)

**Contained Metal Growth**

Polarity: positive

Definition: True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes.

Why it applies: The updated M&I Resource represents a 119% increase in copper metal content over the previously reported Indicated Resource, totaling 10.8 billion pounds of contained copper.

Evidence · text

> The updated M&I Resource represents a 119% increase in copper metal content over the previously reported Indicated Resource

**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: The MRE was prepared and approved by Pierre-Luc Richard, P.Geo., of PLR Resources Inc., an independent qualified person.

Evidence · text

> The independent qualified persons for the MRE, as defined by National Instrument \(“NI”\) 43-101 guidelines, is Pierre-Luc Richard, P.Geo., of PLR Resources Inc.

**NI 43-101 Compliant**

Polarity: positive

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

Why it applies: The mineral resources disclosed conform to standards and guidelines in National Instrument 43-101.

Evidence · text

> The mineral resources disclosed in this news release conform to standards and guidelines in National Instrument 43-101 – Standards of Disclosure for Mineral Projects \(“ NI 43-101 ”\)

**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 MRE is reported at a 0.16% CuEq cut-off grade, and sensitivities at variable cut-offs are provided.

Evidence · text

> Table 1: MRE Base Case at CuEq = 0.16% cut-off.

**Grade Decline**

Polarity: negative

Definition: Average grade dropped >5% vs prior estimate — deposit economics worsening. May indicate high-grading in early drilling.

Why it applies: The new M&I copper grade of 0.27% is significantly lower than the RAG comparable average grade of 0.999%, primarily due to a reduced cut-off grade and the bulk tonnage nature of the pit-constrained resource.

Evidence · text

> 1,834 million tonnes averaging 0.27% Cu \(0.32% CuEq \) of Measured and Indicated categories \(M&I\)

**Dilutive Growth**

Polarity: negative

Definition: Tonnage increased but contained metal flat or down — likely from lower cut-off grade, not geological expansion.

Why it applies: While contained metal and tonnage increased significantly, the average grade decreased due to a lower cut-off grade, indicating growth from including lower-grade material.

Evidence · text

> The updated M&I Resource represents a 119% increase in copper metal content over the previously reported Indicated Resource

**Cut-off Lowered**

Polarity: negative

Definition: Cut-off grade significantly reduced vs prior estimate — tonnage growth may be artificial inflation.

Why it applies: The document explicitly states a reduction of the cut-off grade from 0.12% Cu to 0.09% CuEq, which contributes to the increased tonnage and lower average grade.

Evidence · text

> Reduction of cut-off grade from 0.12% Cu to 0.09% CuEq

**Inferred Resource**

Polarity: negative

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

Why it applies: The MRE includes a substantial Inferred category of 239 million tonnes, which is conceptual in nature and requires further drilling to upgrade confidence.

Evidence · text

> 239 million tonnes averaging 0.41% Cu \(0.46% CuEq\) of Inferred category.

**Resource Update**

Polarity: neutral

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

Why it applies: The announcement provides an updated Mineral Resource Estimate for the Gaspé Copper Project following extensive drilling.

Evidence · text

> Osisko Metals Announces Significant Increase in Mineral Resources at Gaspé Copper

**PEA-Supporting**

Polarity: neutral

Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study.

Why it applies: The MRE is pit-constrained and includes detailed economic parameters for cut-off optimization, indicating its use for economic studies, although no formal economic evaluation has been produced yet.

Evidence · text

> This pit-constrained MRE uses a mathematical lower cut-off of 0.09% CuEq for pit shell optimization and a reporting cut-off grade of 0.16% CuEq for base case in-pit resource estimation

## 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.
