# Cobra Extends Manna Hill Copper Corridor Beyond 2.2 Kilometers & Identifies 2 New Skarns Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/cobra-extends-manna-hill-copper-corridor-beyond-2-2-kilometers-identifies-2-new--10c50549-788a-4ce3-a2cd-405f3b203c1a Original source: https://www.cruxinvestor.com/posts/cobra-extends-manna-hill-copper-corridor-beyond-2-2-kilometers-identifies-2-new-skarns Publisher: cruxinvestor Original announcement: 2026-10-08T00:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-09T12:02:49.013Z Atlas analysis updated: 2026-10-09T12:02:49.013Z - Company: Cobra Resources - Ticker: COBR - Exchange: Unavailable - Region: South Australia - Primary commodity: Copper - Secondary commodities: Gold - Document categories: Other, Drill results - Extracted: 2026-10-09 12:02:49 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Cobra Resources has extended the Blue Rose copper corridor at the Manna Hill Project to over 2.2 km of strike and identified two new skarn systems, Shadow Rose and Neptune Rose. While visual and pXRF observations indicate significant copper anomalism, formal laboratory assay results are expected in 4 to 6 weeks. Reasoning: The company has successfully extended a known copper corridor and identified new targets, but the lack of laboratory assays means the economic significance and exact grades are currently unverified. - Positive factor: strike extension of Blue Rose corridor from 1.6km to >2.2km - Positive factor: identification of two new skarn systems \(Shadow Rose and Neptune Rose\) - Positive factor: continuous copper anomalism up to 60m in Shadow Rose - Positive factor: program objective to establish a substantial resource footprint - Negative factor: current observations are based on qualitative visual logging and semi-quantitative pXRF only - Negative factor: actual assay grades are pending \(4-6 weeks\) Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 7 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The Blue Rose copper corridor was extended from 1.6km to over 2.2km of strike. Evidence · text > extends the Blue Rose copper-bearing corridor from approximately 1.6 kilometers to beyond 2.2 kilometers of strike **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: The current program observations are based on visual logging and pXRF, with laboratory assays still pending. Evidence · text > The observations rest on visual logging and handheld portable X-ray fluorescence readings, with first assays expected in 4 to 6 weeks. ## Extracted facts Stored fact records: 7.

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.
