## Minestarters Atlas summary

Clean Air Metals has confirmed the down-plunge extension of the Escape Deposit at its Thunder Bay North Project via hole EL25-001. The intercept contains PGE-Cu-Ni-rich sulphides that validate the company's geophysical targeting and provide a pathway for significant resource expansion.

Reasoning: The drill hole EL25-001 successfully confirmed a down-plunge extension of the Escape Deposit into a 2.5 km magnetic anomaly, with grades comparable to the existing resource.

- Positive factor: Step-Out Extension

- Positive factor: High-grade sulphide mineralization

- Positive factor: Confirms geophysical target

Facts used in scoring: 23

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: Drilling confirmed the continuation of the Escape Deposit into a previously untested 2.5 km long magnetic anomaly.

Evidence · text

> confirmed the continuation of the Escape Deposit into a previously untested 2.5 km long magnetic anomaly

**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 includes a sign-off by a Qualified Person \(Dr. Lionnel Djon, P.Geo\).

Evidence · text

> Dr. Lionnel Djon, Ph.D., P.Geo., a Qualified Person under National Instrument 43-101

Thunder Bay North Critical Minerals Project · gold

#### Identity

- Hole ID: And
- Project: Thunder Bay North Critical Minerals Project
- Commodity: gold
- Ticker: AIR

#### Geometry

- Grade: 0.14
- Grade Unit: g/t
- Intercept: 11 m
- From: 419 m
- To: 430 m

#### Classification

- Sample Type: drill
- Group ID: And:419-430
- Mining Method: underground

#### Review

- Needs Review: No
- Interp. Status: scored
- Historical: No

#### Dates

- Event date: 2025-10-20T00:00:00.000Z

Reasoning: Expanded from assay table. 0.14 g/t gold is below against the underground mining band \[15, 7, 4, 2.5\] g/t. Grade×width 1.5 g/t·m is below.

- Negative factor: 0.14 g/t gold is below the weak threshold \(2.5 g/t\) on the underground mining band.

- Negative factor: Scored from rubric bands during table expansion, not from document context.

Thunder Bay North Critical Minerals Project · copper

#### Identity

- Hole ID: And
- Project: Thunder Bay North Critical Minerals Project
- Commodity: copper
- Ticker: AIR

#### Geometry

- Grade: 0.52
- Grade Unit: %
- Intercept: 11 m
- From: 419 m
- To: 430 m

#### Classification

- Sample Type: drill
- Group ID: And:419-430
- Mining Method: underground

#### Review

- Needs Review: No
- Interp. Status: scored
- Historical: No

#### Dates

- Event date: 2025-10-20T00:00:00.000Z

Reasoning: Expanded from assay table. 0.52 % copper is moderate against the default band \[2.5, 1, 0.5, 0.25\] %. Grade×width 5.7 %·m is below \(grade alone is moderate; the better of the two is used\).

- Negative factor: Scored from rubric bands during table expansion, not from document context.

Thunder Bay North Critical Minerals Project · nickel

#### Identity

- Hole ID: And
- Project: Thunder Bay North Critical Minerals Project
- Commodity: nickel
- Ticker: AIR

#### Geometry

- Grade: 0.24
- Grade Unit: %
- Intercept: 11 m
- From: 419 m
- To: 430 m

#### Classification

- Sample Type: drill
- Group ID: And:419-430
- Mining Method: underground

#### Review

- Needs Review: No
- Interp. Status: scored
- Historical: No

#### Dates

- Event date: 2025-10-20T00:00:00.000Z

Reasoning: Expanded from assay table. 0.24 % nickel is below against the default band \[3, 1.5, 0.8, 0.3\] %.

- Negative factor: 0.24 % nickel is below the weak threshold \(0.3 %\) on the default band.

- Negative factor: Scored from rubric bands during table expansion, not from document context.

## 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.
