# KNB: Drilling at Dunedoo identifies porphyry-epithermal system Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/knb-drilling-at-dunedoo-identifies-porphyry-epithermal-system--c5e0ad0a-359a-45dc-9eb4-6a01fc2b965f Original source: https://www.asx.com.au/asx/v2/statistics/displayAnnouncement.do?display=pdf&idsId=03145739 Publisher: asx Original announcement: 2026-09-29T22:20:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-09-29T23:23:21.974Z Atlas analysis updated: 2026-09-29T23:23:21.974Z - Company: Koonenberry Gold - Ticker: KNB - Exchange: ASX - Region: NSW - Primary commodity: Gold - Secondary commodities: Copper, Silver, Lead, Zinc - Document categories: Drill results, Other - Extracted: 2026-09-29 23:23:22 UTC Narrative sentiment: 0.10 · Bullish ## Minestarters Atlas summary Koonenberry Gold reported encouraging initial geological observations from its maiden seven-hole drill program at the Dunedoo Project, identifying a potential porphyry-epithermal system based on alteration and veining, with assay results anticipated in early Q4. Additionally, drilling has commenced at the priority Wilga Flats Project, targeting an epithermal gold trend, with historical drilling having identified gold and base metal mineralization, including new gold results from retrospective assays of historical core. Reasoning: Koonenberry Gold's maiden drilling at Dunedoo identified a potential porphyry-epithermal system based on visual observations, with assay results pending, while drilling has commenced at the priority Wilga Flats project, which includes re-reported historical gold and base metal intercepts. - Positive factor: Maiden drilling identified potential porphyry-epithermal system - Positive factor: Drilling commenced at priority Wilga Flats project - Positive factor: QP/CP signed off on exploration results - Positive factor: QA/QC procedures disclosed for KNB's work - Negative factor: No assay results received for Dunedoo drilling - Negative factor: Visual estimates only for Dunedoo observations - Negative factor: Historical nature of some reported results - Negative factor: True width not known for historical intercepts - Negative factor: No QA/QC disclosure for original historical drilling at Wilga Flats Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 3 ## Classification and evidence **First-Pass Drilling** Polarity: neutral Story-specific tag Definition: No canonical definition is currently available. Why it applies: Maiden drilling program at Dunedoo and initial drilling at Wilga Flats are first-pass exploration efforts. Evidence · text > Maiden drilling completed at the Dunedoo Project **No Assay Results** Polarity: negative Story-specific tag Definition: No canonical definition is currently available. Why it applies: The maiden drilling at Dunedoo has only yielded visual estimates, with no assay results received yet. Evidence · text > Visual estimates only – no assay results have been received. **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 announcement includes a Competent Persons Statement signed by Mr Brynache Ellingworth. Evidence · text > The information in this announcement that relates to Exploration Results is based on, and fairly represents, information and supporting documentation prepared by Mr Brynache Ellingworth **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 document details QA/QC procedures including certified labs, standards, blanks, and duplicates for KNB's sampling. Evidence · text > ALS is an ISO/IEC 17025:2005 and ISO9001:2015 certified laboratory. ... A certified standard and blank were inserted every 50th and 51st sample respectively for drilling sampling. A duplicate was taken every 49th and 52nd sample for drilling sampling. **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 historical drill intercepts at Wilga Flats are reported as downhole lengths with no true width provided. Evidence · text > No estimate of true width is provided given the limited historical drilling at Olaf’s with only downhole intervals reported. **Stale Data Re-release** Polarity: negative Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty. Why it applies: The lead and zinc intercept from ODH-1 is a re-reporting of a historical drill intercept from 2024. Evidence · text > Limited historic drilling returned a best result 11.33m @ 2.05% Pb + Zn \(ODH-1\)7 **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: No references were found for sample quality control or QA/QC inserts for the original historical drilling that yielded the lead and zinc intercept. Evidence · text > No references were found for sample quality control or QA/QC inserts \(standards, blanks and duplicates\) for all other historical sampling. ## 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.
