# Aeonian Defines Multiple Copper-Bearing Horizons Along 50-Kilometre Corridor at Koocanusa Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/aeonian-defines-multiple-copper-bearing-horizons-along-50-kilometre-corridor-at--637406fd-7730-4c12-b208-b816a4cdeb54 Original source: https://www.accessnewswire.com/newsroom/en/metals-and-mining/aeonian-defines-multiple-copper-bearing-horizons-along-50-kilometre-corridor-at-k-1218215 Publisher: accesswire Original announcement: 2026-09-11T23:56:23.932Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Aeonian Resources Corp. - Ticker: ALTN - Exchange: Unavailable - Region: British Columbia - Primary commodity: Copper - Secondary commodities: Silver - Document categories: Drill results, Other - Extracted: 2026-09-12 00:00:55 UTC Narrative sentiment: 0.40 · Bullish ## Minestarters Atlas summary Aeonian Resources has updated its geological model for the Koocanusa Copper-Silver Project, identifying a 50-kilometre corridor containing multiple vertically stacked copper-bearing horizons. Recent drilling at the Jake site confirmed the subsurface continuity of these horizons, which are hosted within the Middle Creston Formation. Reasoning: The announcement provides a significant geological reinterpretation that expands the project's scale from individual showings to a vertically stacked 50-km system, though specific assay values for the new horizons are not provided. - Positive factor: identification of multiple stacked copper-bearing horizons - Positive factor: 50-km scale exploration corridor identified - Positive factor: structural controls \(faults\) identified as potential pathways - Positive factor: significant unsampled pipeline \(50 sites\) - Negative factor: drilling only tested a small portion of the regional system - Negative factor: grades and thicknesses not specified for the new horizons Facts used in scoring: 1 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The drilling at Jake is used to reinterpret and expand the understanding of the 50-km western copper trend. Evidence · text > The Jake drilling gave us the subsurface information needed to reinterpret the much larger Koocanusa dataset. **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The release includes a sign-off by a Qualified Person \(Andrew Randell, P.Geo.\). Evidence · text > reviewed and approved by Andrew Randell, P.Geo., President and CEO of Aeonian Resources Corp. and a "Qualified Person" ## Extracted facts Stored fact records: 1.

Status: scored - Historical: No #### Dates - Event date: 2026-09-11T00:00:00.000Z Reasoning: The drilling confirmed the existence of two distinct mineralized bands but did not disclose numeric assay values in this release. - Positive factor: demonstrated subsurface continuity of surface stratigraphic framework - Negative factor: no specific grades or widths reported for the intersections Evidence · text > Drilling encountered two distinct bands of copper mineralization interpreted to represent separate sub-horizons #### Tags used in scoring **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: qaqc\_disclosed is not 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 ## How Atlas produces this analysis Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. 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.
