Summary

Aftermath Silver has commenced new drilling programs at the Berenguela copper target in Peru and the Challacollo silver-gold project in Chile. The company aims to expand the existing Challacollo silver resource and test high-grade copper mineralization at the eastern limits of the Berenguela resource.

Reasoning: The company is actively advancing two projects with new drilling, supported by a substantial existing silver resource at Challacollo and high-grade historical copper at Berenguela.

Positive factors

  • Commencement of new drilling programs at two distinct projects
  • Existing substantial silver resource at Challacollo
  • High-grade historical copper intercepts at Berenguela

Facts used in scoring: 21

Classification and evidence

Step-Out Extensionpositive

Mineralization extended beyond the previously known limit.

Why it applies: Drilling at Berenguela is targeting the eastern limits of the existing MRE to investigate high grade copper mineralization beyond the limits.

Evidence · text

“investigate the potential for high grade copper mineralization beyond the limits of the existing MRE”

NI 43-101 Compliantpositive

Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.

Why it applies: The Challacollo resource estimate is explicitly stated to be prepared in accordance with NI 43-101 standards.

Evidence · text

“NI 43-101 technical report for the Challacollo Mineral Resource Estimate”

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: Dinara Nussipakynova, P.Geo., is named as the Qualified Person for the Challacollo resource estimate.

Evidence · text

“The Qualified Person is Dinara Nussipakynova, P.Geo.”

Inferred Resourcenegative

Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: The Challacollo resource includes a significant Inferred component.

Evidence · text

“Inferred”

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.
