# Kaoko expands Chalkos drilling to 15,000m as Donkey Hill grows Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/kaoko-expands-chalkos-drilling-to-15-000m-as-donkey-hill-grows--0bcaf951-6f47-4c81-a581-4c5f135fa602 Original source: https://stockhead.com.au/resources/kaoko-expands-chalkos-drilling-to-15000m-as-donkey-hill-grows/ Publisher: stockhead Original announcement: 2026-09-23T22:54:52.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-09-23T23:04:02.347Z Atlas analysis updated: 2026-09-23T23:04:02.347Z - Company: Kaoko Metals - Ticker: KAO - Exchange: Unavailable - Region: Namibia - Primary commodity: Copper - Secondary commodities: Silver - Document categories: Drill results, Other - Extracted: 2026-09-23 23:04:03 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Kaoko Metals is expanding its Chalkos copper-silver project drilling campaign to at least 15,000m following successful maiden drilling at Otniel. Additionally, the Donkey Hill copper target has shown increased surface expression, with one rock-chip sample returning over 50% Cu. Reasoning: The company is significantly scaling up its exploration program following encouraging visual results and surface mapping. - Positive factor: drilling program expansion to 15,000m - Positive factor: visual copper mineralisation observed in maiden drilling - Positive factor: surface expression of Donkey Hill growing beyond 1.5km - Positive factor: high-grade rock chip sample \(>50% Cu\) - Negative factor: assay results for Otniel holes are still pending - Negative factor: visual observations are not laboratory assays Facts used in scoring: 3 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The program is testing down-dip extension and stepping laterally to establish geometry. Evidence · text > testing down-dip extension and stepping laterally to establish the geometry **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: While ALS is mentioned as the lab, specific QA/QC protocols \(blanks, standards, etc.\) are not detailed in this update. Evidence · text > Samples from completed holes are being progressively submitted to ALS in South Africa ## Extracted facts Stored fact records: 3.

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.
