# Aftermath Silver Outlines Drill Plan for Challacollo Silver-Gold Project, Chile Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/aftermath-silver-outlines-drill-plan-for-challacollo-silver-gold-project-chile--f8e69343-2cfa-497d-a533-25345dadbfdf Original source: https://money.tmx.com/en/quote/AAG/news/4539195472253009/aftermath-silver-outlines-drill-plan-for-challacollo-silver-gold-project-chile Publisher: tmx Original announcement: 2025-09-23T12:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Aftermath Silver Ltd. - Ticker: AAG - Exchange: TSX - Region: Northern Chile - Primary commodity: Silver - Secondary commodities: Gold - Document categories: Resource update, Drill results - Extracted: 2026-09-19 09:26:53 UTC Narrative sentiment: 0.40 · Bullish ## Minestarters Atlas summary Aftermath Silver has announced a planned 7 to 10-hole diamond drilling program for Q4 2025 at the Challacollo silver-gold project in Chile. The program aims to expand the existing resource by testing known and suspected veins. The company also restated its existing silver-gold mineral resource estimate from November 2020. Reasoning: The document outlines a new exploration drill plan \(high novelty for the program\) while restating a substantial existing silver-gold resource \(historical context\). - Positive factor: Planned drilling program to expand existing resource - Positive factor: Substantial silver resource already established - Positive factor: Clear targets identified for upcoming Q4 2025 program - Negative factor: Resource estimate is historical \(2020\), not new results Facts used in scoring: 21 ## Classification and evidence **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The planned program aims to expand and increase the mineral resource by extending known veins. Evidence · text > Our objective at Challacollo is to expand and increase the mineral resource **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The resource estimate is sourced from an NI 43-101 technical report. Evidence · text > Source: NI 43-101 technical report **Stale Estimate** Polarity: negative Definition: Effective date is >2 years old — data currency concern, may not reflect current geological understanding. Why it applies: The resource estimate effective date is 30 November 2020, which is over 4 years old. Evidence · text > The effective date of the estimate is 30 November 2020. ## Extracted facts Stored fact records: 21.

Why it applies: reporting\_standards includes ni\_43\_101 ## 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.
