Summary
Aftermath Silver announced a new Mineral Resource Estimate for its Berenguela Silver-Copper-Manganese Project in Peru, showing a 28.3% increase in Measured and Indicated (M&I) tonnes to 51.55 Mt. Contained silver in M&I resources increased by 21% to 122.5 Moz, with manganese, copper, and zinc also seeing significant increases. The estimate is NI 43-101 compliant, based on an optimized pit shell, and includes successful conversion of Inferred resources to M&I categories.
Reasoning: The document reports a significant update to the Berenguela project's Mineral Resource Estimate, showing a substantial increase in Measured and Indicated tonnes and contained metal, particularly silver and manganese, which is the primary economic driver. This de-risks the project and enhances its value. The estimate is NI 43-101 compliant with QP sign-off and detailed QA/QC.
Positive factors
- Significant increase in Measured and Indicated (M&I) resources, particularly contained silver and manganese, indicating de-risking and improved confidence.
- Successful conversion of Inferred resources to M&I categories, enhancing resource quality.
- The MRE is NI 43-101 compliant and signed off by a Qualified Person, with robust QA/QC procedures disclosed.
Negative factors
- The effective date of the estimate is November 31, 2025, which is in the future relative to the publication date, suggesting a potential discrepancy or forward-looking statement.
Low confidence — this extraction should be reviewed alongside the original source.

Why it applies: Aftermath instigated a robust industry standard quality assurance/quality control ("QA/QC") program. In the QA/QC program certified reference materials ("CRMs"}, blanks, and duplicate samples were monitored for Ag, Mn, Cu, and Zn; insertion rates were generally between 5% and 10%.
Evidence · text
“Aftermath instigated a robust industry standard quality assurance/quality control ("QA/QC") program. The database for resource estimation consists of historic data as well as data collected by Aftermath. The previous drilling, carried out predominantly by SSR Mining, was validated by twin and replicate holes, and check assays of coarse rejects and sample assay pulps. Aftermath completed a QA/QC program for their core drilling, covering the period 28 th of August 2024 to the 28 th of February 2025. In the QA/QC program certified reference materials ("CRMs"}, blanks, and duplicate samples were monitored for Ag, Mn, Cu, and Zn; insertion rates were generally between 5% and 10%.”

Reasoning: This fact highlights the substantial increase in contained silver in the Measured and Indicated categories, which is a key positive for the project's economics and a primary focus of the announcement.
Positive factors
- Significant increase in M&I contained silver (21.3 Moz or 21%), indicating de-risking and improved confidence.
- High confidence Measured and Indicated category for silver.

Reasoning: This fact represents Inferred manganese resources, which offer future upside but require further work to upgrade confidence.
Positive factors
- Additional manganese resources in the Inferred category provide future exploration potential.
Negative factors
- Inferred resources have lower geological confidence and cannot be used for economic studies without further drilling.

Reasoning: This fact represents an Indicated resource for manganese, adding to the project's primary economic driver with good confidence. (Expanded from multi-commodity resource table for completeness.)
Positive factors
- Indicated category for manganese, showing good geological confidence.
- Significant contained manganese in the Indicated category.

Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
Why it applies: cutoff_grade is stated
QP/CP Signedpositive
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: qp_signed is true
NI 43-101 Compliantpositive
Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.
Why it applies: reporting_standards includes ni_43_101
DFS-Supportingneutral

Reasoning: This fact highlights the substantial increase in contained silver in the Measured and Indicated categories, which is a key positive for the project's economics and a primary focus of the announcement. (Expanded from multi-commodity resource table for completeness.)
Positive factors
- Significant increase in M&I contained silver (21.3 Moz or 21%), indicating de-risking and improved confidence.
- High confidence Measured and Indicated category for silver.

Reasoning: This fact represents Inferred manganese resources, which offer future upside but require further work to upgrade confidence. (Expanded from multi-commodity resource table for completeness.)
Positive factors
- Additional manganese resources in the Inferred category provide future exploration potential.
Negative factors
- Inferred resources have lower geological confidence and cannot be used for economic studies without further drilling.

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.
