# Manhattan Uranium Identifies 3.70% eU3O8 over 5.2 ft in Compilation of 499 Historical Drill Holes at Lisbon Valley, Utah Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/manhattan-uranium-identifies-3-70-eu3o8-over-5-2-ft-in-compilation-of-499-histor--7cc44c67-fb88-4932-8025-665b6be825f7 Original source: https://www.newsfilecorp.com/release/313738/Manhattan-Uranium-Identifies-3.70-eU3O8-over-5.2-ft-in-Compilation-of-499-Historical-Drill-Holes-at-Lisbon-Valley-Utah Publisher: newsfile Original announcement: 2026-09-10T12:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Manhattan Uranium Discovery Corp. - Ticker: MANU - Exchange: Unavailable - Region: Utah - Primary commodity: Uranium - Secondary commodities: None reported - Document categories: Drill results - Extracted: 2026-09-10 12:05:23 UTC Narrative sentiment: 0.40 · Bullish ## Minestarters Atlas summary Manhattan Uranium Discovery Corp. has compiled 499 historical drill holes at its Lisbon Valley uranium project in Utah, identifying a high-grade intercept of 3.70% eU3O8 over 5.2 ft in hole N-1. The compilation shows that 34% of holes hit mineralization averaging 0.28% eU3O8, comparable to the district's historical production grade. This work forms the foundation for 3D targeting and has generated 36 high-priority drill targets, though the data is historical and unverified. Reasoning: Manhattan Uranium has completed a significant compilation of historical drill data at its Lisbon Valley project, revealing high-grade uranium intercepts and an average grade comparable to historical production, which provides a strong basis for future exploration targeting despite the inherent uncertainties of unverified historical eU3O8 data. - Positive factor: Compilation of a large historical drill database provides a foundation for future exploration. - Positive factor: Identification of high-grade historical intercepts, including 3.70% eU3O8 over 1.58m, indicates significant potential. - Positive factor: Average historical grades \(0.28% eU3O8\) are comparable to the district's past production grade \(0.30% U3O8\). - Positive factor: The project is located in a historically significant uranium-producing district with existing infrastructure. - Negative factor: All reported data is historical and has not been independently verified by the company. - Negative factor: eU3O8 values are derived from gamma logging and may not accurately reflect true U3O8 grades due to potential disequilibrium. - Negative factor: Gamma-probe equipment, calibration standards, and conversion parameters used historically are not fully documented. - Negative factor: Reported intervals represent downhole lengths only, with no true thickness provided. Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 39 ## Classification and evidence **Stale Data Re-release** Polarity: negative Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty. Why it applies: The entire news release is based on a compilation of 499 historical drill holes, explicitly stating the data is historical and unverified. Evidence · text > Manhattan Uranium Identifies 3.70% eU3O8 over 5.2 ft in Compilation of 499 Historical Drill Holes at Lisbon Valley, Utah **No QA/QC Disclosure** Polarity: negative Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document. Why it applies: The document explicitly states that 'The gamma-probe equipment, calibration standards, and conversion parameters used by the historical operators are not fully documented, and the Company has not independently verified the original measurements or conversions.' Evidence · text > The gamma-probe equipment, calibration standards, and conversion parameters used by the historical operators are not fully documented, and the Company has not independently verified the original measurements or conversions. **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: The document states that 'Reported intervals represent downhole lengths, not true thicknesses.' Evidence · text > Reported intervals represent downhole lengths, not true thicknesses. **Metal Equivalent Opaque** Polarity: negative Definition: Metal equivalent grade reported without disclosing the price, recovery, or payability assumptions used. Why it applies: The eU3O8 grades are metal equivalents derived from gamma logging, and the document notes potential disequilibrium and undocumented conversion parameters, making the assumptions opaque. Evidence · text > eU₃O₈ = equivalent U₃O₈ from historical downhole gamma \(radiometric\) logging, not chemical assays. Values assume secular equilibrium; disequilibrium, if present, may cause them to overstate or understate true uranium grades. Historical and unverified; for exploration targeting purposes only. **QP/CP Signed** Polarity: positive Story-specific tag 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: The scientific and technical information in the news release has been reviewed and approved by Galen McNamara, P.Geo., CEO and a director of Manhattan, who is a Qualified Person as defined by NI 43-101. Evidence · text > The scientific and technical information in this news release has been reviewed and approved by Galen McNamara, P.Geo., CEO and a director of Manhattan, who is a Qualified Person as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects \(" NI 43-101 "\). **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: the document describes a mill\_cil route \("CIL"\) ## Extracted facts Stored fact records: 39.

Why it applies: the fact restates a prior 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.
