# JAV: Coogee Au-Cu Diamond Hole Intersects Key Structure Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/jav-coogee-au-cu-diamond-hole-intersects-key-structure--6b39b578-3231-4147-b9c0-9ca359de963b Original source: https://www.asx.com.au/asx/v2/statistics/displayAnnouncement.do?display=pdf&idsId=03147118 Publisher: asx Original announcement: 2026-09-30T23:46:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-01T00:13:30.961Z Atlas analysis updated: 2026-10-01T00:13:30.961Z - Company: Javelin Minerals Ltd - Ticker: JAV - Exchange: ASX - Region: WA - Primary commodity: Gold - Secondary commodities: Copper - Document categories: Resource update, Drill results - Extracted: 2026-10-01 00:13:31 UTC Narrative sentiment: 0.00 · Neutral ## Minestarters Atlas summary Javelin Minerals Ltd has completed the first deep diamond hole \(CODD001a\) at its Coogee North gold-copper target in Western Australia, drilled to 819.8m. While the drilling intersected a highly altered and deformed geological sequence consistent with the historic Coogee open pit, downhole magnetic data suggests the source of the large magnetic anomaly was not identified. Assays are pending, and the company is planning an extension or wedge hole to further test the target. Reasoning: Javelin Minerals has completed its first deep diamond hole at Coogee North, intersecting promising geology, but the hole did not directly hit the targeted magnetic anomaly, and assay results are still pending, leading to uncertainty and plans for further drilling. - Positive factor: First deep diamond hole completed - Positive factor: Intersected promising altered and deformed zone - Positive factor: Geological observations consistent with historic pit - Positive factor: Planning for extension/wedge hole - Positive factor: Co-funded by EIS - Negative factor: Assays pending - Negative factor: Did not identify source of magnetic anomaly - Negative factor: Visual estimates are not a proxy for lab analysis Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 8 ## Classification and evidence **Assays Pending** Polarity: negative Story-specific tag Definition: No canonical definition is currently available. Why it applies: The document explicitly states that assay results for the completed drill hole are pending. Evidence · text > Assays Pending **Stale Estimate** Polarity: negative Definition: Effective date is >2 years old — data currency concern, may not reflect current geological understanding. Why it applies: The mineral resource estimates provided in the document have an effective date of July 2024, making them over two years old relative to the announcement date. Evidence · text > Table 3 : Coogee Gold Deposit Mineral Resource Estimate by Classification as of July 2024 **QP/CP Signed** Polarity: positive 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: Mr Mark Cossom is named as a Competent Person who has reviewed the exploration results and mineral resources. Evidence · text > Mr Mark Cossom who is a consultant to Javelin Minerals Ltd and is a current Member of the Australasian Institute of Mining and Metallurgy. Mr Cossom owns shares in Javelin Minerals Ltd. Mr Cossom has sufficient experience, which is relevant to the style of mineralisation and types of deposit under consideration and to the activities undertaken, to qualify as a Competent Person as defined in the 2012 Edition of the “Australasian Code of Reporting of Exploration Results, Mineral Resources and Ore Reserves”. **JORC Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard. Why it applies: The document explicitly references the JORC Code \(2012\) for reporting exploration results and mineral resources. Evidence · text > JORC CODE \(2012\) Table 1 **No New Drill Results** Polarity: negative Story-specific tag Definition: No canonical definition is currently available. Why it applies: The announcement states multiple times that no new assay results are being reported from the current drilling program. Evidence · text > No new results are reported in this ASX Release. **Exploration Drilling** Polarity: neutral Story-specific tag Definition: No canonical definition is currently available. Why it applies: The drilling program is described as testing 'major intrusive gold - copper targets' and 'large geophysical anomalies remain untested by previous drilling'. Evidence · text > First deep diamond hole completed to test the first of two major intrusive gold - copper targets at Coogee North ## Extracted facts Stored fact records: 8.

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.
