# GSN: Mt Dillon Diamond Drilling Completed Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/gsn-mt-dillon-diamond-drilling-completed--9e63fb4f-92af-4f4c-a264-c12f19bdbe9b Original source: https://www.asx.com.au/asx/v2/statistics/displayAnnouncement.do?display=pdf&idsId=03149979 Publisher: asx Original announcement: 2026-10-07T22:33:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-07T23:13:18.095Z Atlas analysis updated: 2026-10-07T23:13:18.095Z - Company: Great Southern Mining Limited - Ticker: GSN - Exchange: ASX - Region: north Queensland - Primary commodity: Gold - Secondary commodities: Copper, Molybdenum, Silver - Document categories: Other, Drill results - Extracted: 2026-10-07 23:13:18 UTC Narrative sentiment: 0.20 · Bullish ## Minestarters Atlas summary Great Southern Mining has completed a maiden diamond drilling campaign at the Mt Dillon target within the Edinburgh Park Project. Two holes were drilled for a total of 1,534.9m, both of which were extended beyond their planned depths. Assay results are expected in late October or early November. Reasoning: The announcement reports the completion of a maiden drilling program but contains no assay results, meaning no new mineralisation data has been disclosed. - Positive factor: completion of maiden diamond drilling - Positive factor: holes extended beyond planned depths - Positive factor: geological features consistent with epithermal system - Positive factor: presence of disseminated pyrite - Negative factor: assay results pending Facts used in scoring: 2 ## Classification and evidence **No QA/QC Disclosure** Polarity: negative Story-specific tag 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: While the document describes QA/QC protocols for the project, no specific assay results or laboratory results for these specific holes are provided to verify. Evidence · text > The presence of economic mineral concentrations will be determined by assay results. ## Extracted facts Stored fact records: 2.

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.
