# Aftermath Silver Berenguela & Challacollo Project Updates Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/aftermath-silver-berenguela-challacollo-project-updates--6b3a980e-43ad-4dd8-a071-b79b6a53a927 Original source: https://www.newsfilecorp.com/release/311364 Publisher: research Original announcement: Unknown date Analysis by Minestarters Atlas Atlas analysis published: 2026-10-16T16:57:24.593Z Atlas analysis updated: 2026-10-16T16:57:24.593Z - Company: Aftermath Silver Ltd. - Ticker: AAG - Exchange: TSXV - Region: Northern Chile - Primary commodity: Silver - Secondary commodities: Gold - Document categories: Resource update, Drill results, Other - Extracted: 2026-10-16 16:57:24 UTC Narrative sentiment: 0.22 · Bullish ## Minestarters Atlas summary Aftermath Silver provided an update on work at its Berenguela and Challacollo projects. The release emphasizes ongoing drilling, geotechnical and metallurgical work, and includes a Challacollo resource table from a 2020 NI 43-101 report. No new drill assay results are reported in this document. Reasoning: The main current event is a project update that includes a historical Challacollo resource table and ongoing drill/program progress at Berenguela and Challacollo. The resource table is the most structured technical disclosure, but its source date is older and the document mainly updates work programs rather than announcing a new estimate or new assays. - Positive factor: Includes a mineral resource estimate for Challacollo with Indicated and Inferred categories - Positive factor: Qualified person review and NI 43-101 technical report reference are disclosed - Positive factor: Ongoing drilling is described as testing extensions and upgrading resources - Negative factor: Resource table is historical \(technical report dated 2020\) - Negative factor: No new assays or fresh drill intercept numbers are reported in this release for Challacollo - Negative factor: Cut-off grade for the estimate is not stated in the table - Rubric flag: resource\_update historical restatement — The Challacollo table is a historical estimate from a 2020 technical report; keep novelty low and do not treat it as a new resource announcement. - Rubric flag: mining\_relevant document scope — The release is primarily a project update with ongoing drilling and development work; the only extractable resource facts are from a historical table. Facts used in scoring: 18 ## Classification and evidence **JORC Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard. Why it applies: The release states the Challacollo resource source is a NI 43-101 technical report, not JORC, but the estimate is explicitly NI 43-101 compliant. Evidence · text > NI 43-101 technical report for the Challacollo Mineral Resource Estimate **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The Challacollo estimate is explicitly tied to a NI 43-101 technical report and qualified person sign-off is disclosed. Evidence · text > NI 43-101 technical report for the Challacollo Mineral Resource Estimate **QP/CP Signed** Polarity: positive Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: A named qualified person is disclosed and approves the release. Evidence · text > Qualified person Michael Parker **Historical Estimate Only** Polarity: negative Definition: Estimate pre-dates or does not comply with current JORC/NI 43-101 standards — requires verification drilling. Why it applies: The resource table is sourced to a 2020 technical report and is restated in a 2026 update rather than announcing a new estimate. Evidence · text > announced on December 15, 2020 **No Cut-off Disclosed** Polarity: negative Story-specific tag Definition: No canonical definition is currently available. Why it applies: The resource table excerpt does not state a cut-off grade, limiting comparability. Evidence · text > Assumptions used in the MRE can be found in the NI 43-101 technical report **Other** Polarity: neutral Story-specific tag Definition: No canonical definition is currently available. Why it applies: The document is mainly a project update with ongoing drilling and development work rather than fresh assay disclosure. Evidence · text > provide an update to the ongoing work programs ## Extracted facts Stored fact records: 18.

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.
