## Minestarters Atlas summary

North Shore Uranium Ltd. has filed a permit application for its Rio Puerco uranium project in New Mexico and staked 19 new mining claims. The company is preparing for a 2026 drill program designed to validate and expand upon a historical, non-NI 43-101 compliant uranium resource.

Reasoning: The company is advancing the Rio Puerco project through permitting and claim staking in preparation for a 2026 drill program aimed at validating a historical uranium resource.

- Positive factor: Permit application filed for drilling

- Positive factor: New mining claims staked to expand footprint

- Positive factor: Planned 2026 drill program to validate historical resource

- Negative factor: Historical resource is not NI 43-101 compliant

- Negative factor: Historical resource has not been verified by the current company

Facts used in scoring: 2

## Classification and evidence

**Historical Estimate Only**

Polarity: negative

Definition: Estimate pre-dates or does not comply with current JORC/NI 43-101 standards — requires verification drilling.

Why it applies: The resource mentioned is a 2009 estimate based on 1960s/70s data and is explicitly stated as not NI 43-101 compliant.

Evidence · text

> It is a historical estimate and not current and does not comply with Canadian NI 43-101 guidelines

**Inferred Resource**

Polarity: negative

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

Why it applies: The historical resource is categorized as JORC-compliant inferred.

Evidence · text

> Monaro reported a JORC Code \(2004\)-compliant inferred resource

**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 release includes a sign-off by a Qualified Person \(Brooke Clements\) who has reviewed the technical data.

Evidence · text

> Mr. Brooke Clements, MSc, P.Geol., a Qualified Person... has reviewed and approved of the scientific and technical disclosure

## 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.
