## Minestarters Atlas summary

Aston Bay has filed an initial NI 43-101 Technical Report detailing a Mineral Resource Estimate for the Storm Copper Project in Nunavut. The estimate includes 8.2 Mt of Indicated and 3.3 Mt of Inferred resources at 1.47% Cu and 1.30% Cu respectively, primarily accessible via open-pit mining.

Reasoning: The filing of an initial Mineral Resource Estimate for a high-grade copper-silver project is a major de-risking milestone.

- Positive factor: Significant copper tonnage and grade

- Positive factor: Maiden resource estimate

- Positive factor: High M&I percentage for near-surface

- Positive factor: QA/QC disclosed with certified lab

- Positive factor: QP/CP signed

- Negative factor: Large Inferred component in global total

Facts used in scoring: 30

## Classification and evidence

**Maiden Resource**

Polarity: neutral

Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component.

Why it applies: The report details an 'Initial Mineral Resource Estimate' for the Storm Copper Project.

Evidence · text

> Initial Mineral Resource Estimate and Technical Report on the Storm Copper Project

**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: Yungang Wu, M.Sc., P.Geo. of P&E Mining Consultants Inc. is named as the Qualified Person.

Evidence · text

> Yungang Wu, M.Sc., P.Geo. of P&E Mining Consultants Inc. is the Qualified Person responsible for the completion of the Mineral Resource Estimation

**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 report explicitly states the Cu cut-off of 0.35% for open pit and 1.0% for underground.

Evidence · text

> applying a lower cut-off grade of 0.35% Cu.

**QA/QC Disclosed**

Polarity: positive

Story-specific tag

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

Why it applies: The report details the use of blanks, duplicates, and certified reference materials \(CRM\) and names ALS Global as the accredited lab.

Evidence · text

> Blank, duplicate, and certified reference materials \(CRM\), were inserted into the sample sequence

## 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.
