The program aims to twin historical Kerr-McGee holes to validate a 2009 historical inferred resource of 6.0 Mt at 0.09% eU3O8. Reasoning: The company is advancing toward a drilling program to validate a significant historical uranium resource, representing a clear path toward NI 43-101 compliance. - Positive factor: Engagement of experienced drill contractor Harris Exploration - Positive factor: Clear plan to twin historical holes to validate resource - Positive factor: Regulator site visits completed to aid permitting - Negative factor: Reliance on unverified historical data - Negative factor: Permitting still pending Facts used in scoring: 2 ## Classification and evidence **Nearology Play** Polarity: neutral Story-specific tag Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: The project is located in the Grants Uranium District, a major historic producer. Evidence · text > Rio Puerco is located at the eastern end of the Grants Uranium District which is the largest historic producer of uranium in the United States **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 explicitly categorized as an inferred resource. Evidence · text > Monaro reported a JORC Code \(2004\)-compliant inferred resource **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 estimate provided is a historical one from 2009 and has not been verified by the current company. Evidence · text > The Historical Resource outlined in this news release has not been verified and should not be relied upon. It is a historical estimate ## Extracted facts Stored fact records: 2.

Cannot support economic studies alone. Why it applies: category is "inferred" **Cut-off Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison. Why it applies: cutoff\_grade is stated **JORC Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard. Why it applies: reporting\_standards includes jorc **Stale Estimate** Polarity: negative Definition: Effective date is >2 years old — data currency concern, may not reflect current geological understanding. Why it applies: effective date is 17.3 years before this release ## 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.
