The hole intersected 13.6 m grading 0.53% U3O8, including 1.1 m grading 4.81% U3O8, and a highest-grade sample of 8.16% U3O8 over 0.5 m. This discovery extends the Mineralized RIB Corridor and is considered the best exploration hole drilled to date at the project. Reasoning: ATHA Energy has announced a new high-grade uranium discovery at its Angilak Project, with the maiden drillhole RIBN-DD-001 returning exceptional grades up to 8.16% U3O8 over 0.5 m and a significant composite interval of 13.6 m grading 0.53% U3O8. This discovery extends the Mineralized RIB Corridor and is considered the best exploration hole drilled to date at the project, indicating high materiality and novelty. The technical information is supported by a Qualified Person and accredited laboratory, although true widths are yet to be determined. - Positive factor: New high-grade discovery in maiden drillhole - Positive factor: Exceptional uranium grades up to 8.16% U3O8 - Positive factor: Significant composite mineralization length of 13.6 m at 0.53% U3O8 - Positive factor: Discovery extends the Mineralized RIB Corridor - Positive factor: QP/CP signed off on technical information - Positive factor: Certified laboratory used for assays - Positive factor: Compositing parameters clearly disclosed - Negative factor: True width of intercepts not yet determined Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 3 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: The document reports uranium grades of 4.81% U3O8 and 8.16% U3O8, which are well above the exceptional threshold of 2% U3O8 for uranium. Evidence · text > 1.1 m Grading 4.81% U3O8, and Grades Up to 8.16% U3O8 **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The RIB North Discovery is situated along the 4.4 km eastern limb of the Mineralized RIB Corridor, and the maiden hole represents a new discovery area along this trend. Evidence · text > RIBN-DD-001, at the RIB North Discovery as the best exploration hole drilled to date at the Angilak Uranium Project **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 states that core samples are submitted to the Saskatchewan Research Council \(SRC\) Geoanalytical Laboratories, which is ISO/IEC 17025:2005 accredited, and the technical information has been reviewed and approved by a Qualified Person. Evidence · text > Core samples are submitted to the Saskatchewan Research Council \(SRC\) Geoanalytical Laboratories in Saskatoon. The SRC facility is ISO/IEC 17025:2005 accredited by the Standards Council of Canada \(scope of accreditation \#537\). ... The scientific and technical information contained in this news release have been reviewed and approved by Cliff Revering, P.Eng., Vice President, Exploration of ATHA, who is a "qualified person" under National Instrument 43-101 **Compositing Transparent** Polarity: positive Definition: Cut-off grade and internal dilution rules are clearly stated for reported intervals. Why it applies: The document clearly states the cutoff grade and maximum internal dilution used for calculating composite mineralization. Evidence · text > Composite mineralization is calculated using a 0.01% U3O8 cutoff with a maximum internal dilution of 1.5 m. **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 explicitly states that all drill intercepts are core width and true thickness is yet to be determined. Evidence · text > All drill intercepts are core width and true thickness is yet to be determined. **Maiden Resource** Polarity: neutral Story-specific tag Definition: First formal MRE for the project — establishes baseline but typically exploration-stage with high Inferred component. No prior estimate exists, so every change band is not applicable. Why it applies: The results are from the company's maiden drillhole at the RIB North Discovery, marking a new discovery. Evidence · text > Assays confirm the Company's maiden drillhole, RIBN-DD-001, at the RIB North Discovery as the best exploration hole drilled to date at the Angilak Uranium Project ## Extracted facts Stored fact records: 3.

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.
