# ATHA Energy Announces Additional Results from Rib North Discovery Expanding Continuity of Mineralization from 300 metres to 1.45 Kilometres – Results Include RIBN-DD-011 Intersecting 20 m of Composite Uranium Min Including 1.3 m of High-Grade Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/atha-energy-announces-additional-results-from-rib-north-discovery-expanding-cont--879f69f0-80cb-4742-a60d-98b2d819ad95 Original source: https://www.accessnewswire.com/newsroom/en/metals-and-mining/atha-energy-announces-additional-results-from-rib-north-discovery-expanding-conti-1217933 Publisher: accesswire Original announcement: 2026-09-08T11:16:02.920Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: ATHA Energy Corp. - Ticker: SASK - Exchange: Unavailable - Region: Nunavut, Canada - Primary commodity: Uranium - Secondary commodities: None reported - Document categories: Drill results - Extracted: 2026-09-08 11:18:54 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary ATHA Energy announced additional drill results from its 2026 Angilak Exploration Program at the Rib North Discovery, extending uranium mineralization continuity from 300 meters to 1.45 kilometers. All seven new drillholes intersected uranium mineralization, with highlights including 1.5 meters at 8,453 CPS in RIBN-DD-011 and 4.0 meters at 1,013 CPS in RIBN-DD-013A. The company notes that grades are currently reported as counts per second \(CPS\) from downhole gamma probes, with true thickness yet to be determined. Reasoning: The drill program successfully extended the known uranium mineralization at Rib North, demonstrating continuity over a significant strike length through successful step-out drilling. However, the reported grades are in CPS, not U3O8 assays, which limits direct quantitative assessment of grade quality, and true thickness is not yet determined. - Positive factor: Expanded strike length of mineralization to 1.45 km - Positive factor: All seven new drillholes intersected uranium mineralization - Positive factor: Successful step-out drilling - Positive factor: QA/QC procedures disclosed and QP signed off - Positive factor: Certified laboratory used - Negative factor: Grades reported as CPS \(counts per second\) from gamma probes, not U3O8 assays - Negative factor: True thickness of intercepts not yet determined Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 4 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The drilling program is focused on widely spaced step-outs designed to outline the continuity of uranium mineralization, expanding the known strike length. Evidence · text > Drilling is focused on widely spaced step-outs, designed to outline the continuity of uranium mineralization at RIB North - the discovery remains open in all directions **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 an ISO/IEC 17025:2005 accredited laboratory \(SRC Geoanalytical Laboratories\) and the technical information has been reviewed and approved by a Qualified Person \(Cliff Revering, P.Eng.\) under NI 43-101. 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" as defined under National Instrument 43-101 - Standards of Disclosure for Mineral Projects. **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. **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: 4.

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.
