# Cobra Cut One Planned Hole & Logged Copper to 300 Metres Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/cobra-cut-one-planned-hole-logged-copper-to-300-metres--19bc6958-881e-43a3-bc5b-f616e9b68a49 Original source: https://www.cruxinvestor.com/posts/cobra-cut-one-planned-hole-logged-copper-to-300-metres Publisher: cruxinvestor Original announcement: 2026-08-28T00:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Cobra Resources - Ticker: COBR - Exchange: Unavailable - Region: Unavailable - Primary commodity: Copper - Secondary commodities: Gold - Document categories: Drill results, Other - Extracted: 2026-08-28 15:17:18 UTC Narrative sentiment: 0.40 · Bullish ## Minestarters Atlas summary Cobra Resources reported that redirected drilling at Manna Hill has extended observed sulfide mineralization to 300m depth, suggesting the skarn system connects to a larger porphyry. While visual observations of bornite and chalcopyrite are encouraging, laboratory assays for these new depths are still outstanding. Reasoning: The drilling confirmed depth continuity of sulfides to 300m and suggested the skarn is part of a larger porphyry system, though key assays are still pending. - Positive factor: depth continuity of mineralization - Positive factor: extension of system into porphyry halo - Positive factor: unexpected copper oxide discovery - Negative factor: assays for new depth continuity are outstanding - Negative factor: target abandoned due to high pyrite - Negative factor: new oxide zone lacks width/orientation measurements Facts used in scoring: 4 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The document mentions a diamond hole stepped out to the south which hit copper oxide, opening extension in that direction. Evidence · text > One diamond hole was stepped out and drilled from the south... hit copper oxide very shallowly to the south, which opens extension in that direction **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 release describes visual observations and mentions assays are outstanding but does not detail QA/QC protocols or lab certification. Evidence · text > These remain visual observations, and management's stated optimism about them is cautious pending laboratory results. ## Extracted facts Stored fact records: 4.

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.
