## Minestarters Atlas summary

North Shore Uranium reported positive Phase 1 drill results from its Rio Puerco uranium project in New Mexico, with all 13 holes intersecting significant uranium mineralization. Highlights include 27.0 ft at 0.30% eU3O8 in hole RP-26-18-39. The results confirm mineralization within historical resource sandstone units and are favorable for potential in-situ-recovery \(ISR\) mining, with all 21 intercepts below the water table, advancing the project towards a NI 43-101 compliant resource.

Reasoning: North Shore Uranium's Phase 1 drill program at Rio Puerco delivered positive results, confirming significant uranium mineralization in all holes and validating historical data. The intercepts, including strong grades, are favorable for ISR mining and represent a crucial step towards defining a modern resource, despite being based on eU3O8 estimates rather than chemical assays.

- Positive factor: Significant uranium mineralization confirmed in all 13 Phase 1 drill holes.

- Positive factor: Intercepts are favorable for in-situ-recovery \(ISR\) mining, being below the water table.

- Positive factor: Best intercepts show strong uranium grades \(e.g., 0.30% eU3O8 over 27.0 ft\).

- Positive factor: Drilling confirmed mineralization in key sandstone units hosting historical resources.

- Positive factor: True widths are assumed due to vertical holes and horizontal geology, providing clarity on geometry.

- Positive factor: QA/QC procedures for eU3O8 estimation and QP sign-off enhance data credibility.

- Negative factor: Grades are equivalent uranium \(eU3O8\) from gamma logging, not chemical assays, which may vary.

- Negative factor: The program is primarily for validating historical data, not a new discovery.

Low confidence — this extraction should be reviewed alongside the original source.

## Classification and evidence

**Strong Grade**

Polarity: positive

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: The intercept in RP-26-18-39 of 0.295% eU3O8 over 8.23m and RP-26-18-640 of 0.331% eU3O8 over 3.81m are strong grades for uranium, exceeding the moderate threshold of 0.1% eU3O8.

Evidence · table

> 0.295

Context: 27.0

**True Width Disclosed**

Polarity: positive

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

Why it applies: The document states that 'All intersections are assumed to be true widths given the vertical holes and the interpreted horizontal sandstone layers hosting the mineralization'.

Evidence · text

> All intersections are assumed to be true widths given the vertical holes and the interpreted horizontal sandstone layers hosting the mineralization.

**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 detailed descriptions of downhole geophysical logging, calibration procedures, and QP sign-off for the eU3O8 estimation.

Evidence · text

> Upon completion of each drill hole, a downhole geophysical survey was completed by Century Geophysical Corporation \("Century"\) using a calibrated multi-parameter logging tool.

**Compositing Transparent**

Polarity: positive

Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals.

Why it applies: The cutoff grade of 0.02% eU3O8 and a minimum grade x thickness of 0.30 are clearly stated for the reported intervals.

Evidence · text

> Cutoff grade of 0.02% eU3O8 and a minimum grade x thickness of 0.30

**Infill Drilling**

Polarity: neutral

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

Why it applies: The drill program's objective is to 'twin' historical holes and validate historical exploration data, which is characteristic of infill drilling.

Evidence · text

> Each of the sites selected for drilling in 2026 is a "twin" of a mud rotary hole drilled by Kerr-McGee

**Metal Equivalent Assumptions Disclosed**

Polarity: positive

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: The document states that a disequilibrium factor of 1.0 was applied for the eU3O8 estimation.

Evidence · text

> A disequilibrium factor of 1.0 was applied based on a review of an historical chemical assay and close can assay study completed by Kerr-McGee in the 1970s

**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: Brooke Clements, MSc, P.Geol., a Qualified Person, and Chris Longton, Principal Geologist, also a Qualified Person, reviewed and approved the technical disclosure.

Evidence · text

> Mr. Brooke Clements, MSc, P.Geol., a Qualified Person as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects and the President and CEO of North Shore, has reviewed and approved of the scientific and technical disclosure in this press release.

**eU3O8 Only**

Polarity: negative

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: The reported grades are equivalent uranium \(eU3O8\) derived from gamma logging and have not been verified by chemical assays, which introduces potential variability.

Evidence · text

> eU3O8values are equivalent uranium grades derived from calibrated downhole gamma logging and the results presented in this news release have not been verified by chemical assays.

**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 document discusses a historical resource estimate from 2009 that is not NI 43-101 compliant and has not been verified by a Qualified Person.

Evidence · text

> A historical resource estimate of 6.0 million tonnes at an average grade of 0.09% eU3O8for 11.4 million pounds of U3O8was reported for Rio Puerco in 2009 by Monaro Mining NL

## 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.
