# Aftermath Silver Outlines Drill Plan for Challacollo Silver-Gold Project, Chile Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/aftermath-silver-outlines-drill-plan-for-challacollo-silver-gold-project-chile--2a94d72f-51d6-40ae-8929-08376ff5ae65 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: Other, Resource update - Extracted: 2026-08-24 08:04:06 UTC Narrative sentiment: 0.30 · 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 mineral resource by testing down-dip extensions and new veins. The company also provided a summary of the current NI 43-101 compliant mineral resource estimate. Reasoning: The announcement outlines a new exploration drill plan to expand an existing resource, which is a positive development, though the resource data itself is a restatement of a 2020 estimate. - Positive factor: Planned exploration drilling to expand existing resource - Positive factor: Substantial existing silver resource - Positive factor: Clear drilling targets \(Lolón North, Lucy North, etc.\) - Negative factor: Resource estimate is historical \(effective 2020\) Facts used in scoring: 20 ## Classification and evidence **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The document provides a summary of the existing mineral resource estimate as part of the drill plan announcement. Evidence · text > Challacollo is a highly prospective low-sulphidation epithermal Ag-Au vein deposit containing a substantial silver resource \(see Table 1 below\). **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: A significant portion of the reported resource is in the Inferred category. Evidence · table > Inferred Context: 2,360 **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 stated to be prepared in accordance with NI 43-101 standards. Evidence · text > Source: NI 43-101 technical report for the Challacollo Mineral Resource Estimate ## Extracted facts Stored fact records: 12.

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.
