# ARO: Guajaraz Drilling Update - Revision Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/aro-guajaraz-drilling-update-revision--4251084e-9ea9-4eb2-be5e-4fab1de463dd Original source: https://www.asx.com.au/asx/v2/statistics/displayAnnouncement.do?display=pdf&idsId=03148049 Publisher: asx Original announcement: 2026-10-02T06:55:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-02T07:02:01.019Z Atlas analysis updated: 2026-10-02T07:02:01.019Z - Company: Altoro Metals Limited - Ticker: ARO - Exchange: ASX - Region: central Spain - Primary commodity: Zinc - Secondary commodities: Lead, Silver, Copper - Document categories: Other, Drill results - Extracted: 2026-10-02 07:02:01 UTC Narrative sentiment: 0.00 · Neutral ## Minestarters Atlas summary Altoro Metals provides an update on its maiden diamond drilling programme at the Guajaraz Zn-Pb-Ag-Cu Project in Spain. Three holes have been completed and two are in progress, with visual evidence of zinc mineralisation in hole G-03, though assay results are expected in approximately six weeks. Reasoning: The document is a drilling update providing progress on a maiden programme but explicitly states that no assay results are available yet. It also serves as a formal revision to a previous announcement to include required regulatory cautionary statements. - Positive factor: drilling progress continues - Positive factor: zinc mineralisation confirmed visually in G-03 - Negative factor: no assay results reported - Negative factor: revision required due to omission of cautionary statement 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: The announcement states that assay results are expected within 6 weeks and no laboratory or QA/QC protocols for the current results are detailed. Evidence · text > assay results expected within 6 weeks ## Extracted facts Stored fact records: 2.

Why it applies: qaqc\_disclosed is true **Cut-off Undisclosed** Polarity: negative Definition: High-grade interval reported without stating the cut-off grade used for compositing. Why it applies: no cutoff\_grade was stated **Nearology Play** Polarity: neutral Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: proximity is offered as the value premise: "1,400 metres of drilling, designed principally to test for deep-seated carbonate-hosted replacement-style zinc mineralis" ### G-03 [Link to this fact](https://atlas-staging.minestarters.com/news/aro-guajaraz-drilling-update-revision--4251084e-9ea9-4eb2-be5e-4fab1de463dd#fact-drill-facts-1) Guajaraz Zn-Pb-Ag-Cu · zinc #### Identity - Hole ID: G-03 - Project: Guajaraz Zn-Pb-Ag-Cu - Commodity: zinc - Region: spain - Reported Region: spain - Ticker: ARO #### Geometry - Intercept: 0.14 m - From: 114.51 m - To: 114.65 m - Intercept Depth: 114.51 m #### Classification - Sample Type: drill - Group ID: G-03:114.51-114.65 #### Location - Location: Central Zone - Loc.

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.
