# Andina Copper Intersects 126 m at 0.46% Cu, 0.53 g/t Au, 2.14 g/t Ag within wide Cu-Au-Ag Interval at Piuquenes East Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/andina-copper-intersects-126-m-at-0-46-cu-0-53-g-t-au-2-14-g-t-ag-within-wide-cu--46d6bc9d-2ce0-4c9b-ae41-a4a4727fc235 Original source: https://money.tmx.com/en/quote/ANDC/news/7854431559671732/andina-copper-intersects-126-m-at-0-46-cu-0-53-g-t-au-2-14-g-t-ag-within-wide-cu Publisher: tmx Original announcement: 2026-03-17T12:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Andina Copper Corp. - Ticker: ANDC - Exchange: TSX - Region: San Juan Province, Argentina - Primary commodity: Copper - Secondary commodities: Gold, Silver - Document categories: Drill results, Other - Extracted: 2026-09-15 10:53:40 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Andina Copper reported a significant 126 m wide copper-gold-silver intercept at the Piuquenes East project in Argentina. The drill hole PIU09 confirms the vertical extent of the porphyry system and shows increasing gold grades and veining intensity at depth. Reasoning: The intercept of 126 m at 0.46% Cu and 0.53 g/t Au represents a significant expansion of the porphyry system at depth with increasing grade signatures. - Positive factor: significant vertical expansion of mineralized envelope - Positive factor: increasing gold grades and veining intensity at depth - Positive factor: broad continuous interval - Positive factor: QA/QC protocols disclosed - Negative factor: true width not yet determined Facts used in scoring: 8 ## Classification and evidence **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: Release details the use of ALS Minerals, certified reference materials, blanks, and duplicates. Evidence · text > The Company implemented a quality assurance and quality control \(QA/QC\) program that included the insertion of certified reference materials, blanks, and duplicates **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The intercept significantly expands the vertical extent of the mineralized envelope at Piuquenes East.

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.
