## Minestarters Atlas summary

Osisko Metals announced new drill results from its Gaspé Copper Project in Eastern Québec, highlighting significant intercepts aimed at expanding and upgrading the mineral resource. Key results include 320.5 metres averaging 0.38% Cu in DDH 30-1198 and 337.0 metres averaging 0.35% Cu in DDH 30-1203. The drilling successfully extended mineralization and identified potential for converting in-pit waste rock into new mineralized zones, contributing to the project's overall resource growth.

Reasoning: Osisko Metals reported new drill results from its Gaspé Copper Project, including several long intercepts that expand the known mineralization both within and outside the current resource model. While copper grades are generally moderate compared to historical highs, the extensive widths and strategic focus on resource expansion and conversion are positive. The results are supported by robust QA/QC and QP sign-off.

- Positive factor: Significant intercept lengths

- Positive factor: Expansion of known mineralization

- Positive factor: Potential for resource conversion

- Positive factor: High confidence in results due to QA/QC and QP sign-off

- Negative factor: Copper grades generally below prior project average

## Classification and evidence

**QA/QC Disclosed**

Polarity: positive

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Why it applies: The release explicitly states that Osisko Metals adheres to a strict QA/QC program for core handling, sampling, sample transportation and analyses, including insertion of blanks and standards in the sample stream, and that samples are analyzed by ALS Canada Ltd.

Evidence · text

> Osisko Metals adheres to a strict QA/QC program for core handling, sampling, sample transportation and analyses, including insertion of blanks and standards in the sample stream. Drill core is drilled in HQ or NQ diameter and securely transported to its core processing facility on site, where it is logged, cut and sampled. Samples selected for assay are sealed and shipped to ALS Canada Ltd.’s preparation facility in Sudbury. Sample preparation details \(code PREP-31DH\) are available on the ALS Canada website. Pulps are analyzed at the ALS Canada Ltd. facility in North Vancouver, BC. All samples are analyzed by four acid digestion followed by both ICP-AES and ICP-MS for Cu, Mo and Ag.

**True Width Disclosed**

Polarity: positive

Definition: Actual thickness perpendicular to structure is stated, not just downhole length.

Why it applies: The document states that true widths are estimated at 90 – 92% of the reported core length intervals.

Evidence · text

> True widths are estimated at 90 – 92% of the reported core length intervals.

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The document explicitly refers to 'Expansion' intercepts located outside the 2026 MRE model, which may lead to the definition of new resources.

Evidence · text

> “Expansion” intercepts are located outside the 2026 MRE model and comprise either A\) in-pit expansion, which offers potential to convert in-pit waste into additional resources within the 2026 MRE Whittle pit, or B\) out-of-pit expansion, consisting of mineralization located out of the 2026 MRE Whittle pit, which may potentially lead to the definition of new resources.

**Infill Drilling**

Polarity: neutral

Definition: Confirmatory drilling to raise resource confidence, not new discovery.

Why it applies: The document mentions 'infill' intercepts located within the 2026 MRE model, focused on upgrading Inferred Mineral Resources to Measured or Indicated categories.

Evidence · text

> Reported “infill” intercepts are located within the 2026 MRE model \( see April 14, 2026 news release \), and will be focused on upgrading Inferred Mineral Resources to Measured or Indicated categories, as applicable.

**QP/CP Signed**

Polarity: positive

Story-specific tag

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 news release states that the scientific and technical content has been reviewed and approved by Mr. Bernard-Olivier Martel, P. Geo., an independent 'qualified person' as defined by NI 43-101.

Evidence · text

> The scientific and technical content of this news release has been reviewed and approved by Mr. Bernard-Olivier Martel, P. Geo. \(OGQ 492\), an independent “qualified person” as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects \(“NI 43-101”\).

**Cut-off Disclosed**

Polarity: positive

Story-specific tag

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

Why it applies: The document specifies that mineralized intervals are calculated using an average 0.12% CuEq lower cut-off.

Evidence · text

> Mineralized intervals reported herein are calculated using an average 0.12% CuEq lower cut-off over contiguous 20-metre intersections \(shorter intervals as the case may be at the upper and lower limits of reported intervals\).

Reasoning: This significant intercept with a silver grade well above the project average contributes positively to resource expansion.

- Positive factor: Significant intercept length

- Positive factor: Silver grade is well above project average

- Positive factor: Expansion drilling outside MRE model

## 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.
