# 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-staging.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--89274228-5512-4d92-871f-04dae9efecec 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: 2026-08-22 22:41:37 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Andina Copper reported a significant 126 m wide intercept at the Piuquenes East project, containing 0.46% Cu, 0.53 g/t Au, and 2.14 g/t Ag. The results indicate a vertically extensive porphyry system with 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 mineralized system at Piuquenes East, with increasing grades observed at depth. - Positive factor: significant vertical expansion of mineralized envelope - Positive factor: increasing gold grades at depth - Positive factor: wide continuous intercept - Positive factor: presence of porphyry stockwork veining - Negative factor: true widths not yet determined Facts used in scoring: 6 ## 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 laboratory, 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. Evidence · text > significantly expands the vertical extent of the mineralized envelope ## Extracted facts Stored fact records: 6.

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.
