# F3 Uranium: Drilling Intersects Anomalous Radioactivity 1km East of Tetra Zone Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/f3-uranium-drilling-intersects-anomalous-radioactivity-1km-east-of-tetra-zone--63d5dbaa-2630-406c-bd96-67866ff46a76 Original source: https://www.juniorminingnetwork.com/junior-miner-news/press-releases/1283-tsx-venture/fuu/213277-drilling-intersects-anomalous-radioactivity-1km-east-of-tetra-zone.html Publisher: jmn Original announcement: 2026-10-21T19:48:06.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-21T10:17:19.694Z Atlas analysis updated: 2026-10-21T10:17:19.694Z - Company: F3 Uranium Corp. - Ticker: FUU - Exchange: TSXV - Region: Saskatchewan - Primary commodity: Uranium - Secondary commodities: Gold - Document categories: Drill results, Other - Extracted: 2026-10-21 10:17:20 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary F3 Uranium has reported anomalous handheld spectrometer readings of up to 4,400 cps in drill hole PLN26-232, located approximately 1km east of the Tetra Zone discovery. This represents the highest radioactivity recorded in an exploration hole on the PLN Project outside the JR and Tetra Zones. Assay results for the new intercepts are currently pending. Reasoning: The discovery of anomalous radioactivity \(4,400 cps\) in a 1km step-out from the Tetra Zone is a significant exploration milestone, though the lack of confirmed assay grades for the primary hole limits immediate confidence. - Positive factor: Step-Out Extension - Positive factor: Anomalous radioactivity detected 1km east of known Tetra Zone - Negative factor: Assay results for the most significant hole \(PLN26-232\) are still pending - Negative factor: Handheld spectrometer readings are preliminary and not a substitute for assays 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 anomalous radioactivity was found in a 1km step-out to the east from the Tetra Zone. Evidence · text > for the first time in a 1km stepout to the east from the Tetra Zone **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 discloses the use of an accredited laboratory \(SRC Geoanalytical Laboratories\) and mentions standard QA/QC protocols. Evidence · text > independent laboratory SRC Geoanalytical Laboratories \(an SCC ISO/IEC 17025: 2005 Accredited Facility\) ## 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.
