Summary
Aftermath Silver has commenced a 6,000m drilling campaign at its Berenguela silver-copper-manganese project in Peru and is starting a new drilling program at the Challacollo silver-gold project in Chile. The company is focusing on resource expansion and upgrading resource confidence through infill and step-out drilling.
Reasoning: The announcement details active drilling at Berenguela and the commencement of drilling at Challacollo, supported by recent resource updates at both projects.
Positive factors
- Ongoing drilling programs at two distinct projects
- Recent significant resource update at Berenguela
- High-grade historical intercepts mentioned as targets
Facts used in scoring: 22
Classification and evidence
Infill Drillingneutral
Confirmatory drilling to raise resource confidence, not new discovery.
Why it applies: The Berenguela program aims to infill drill to convert inferred resources to measured and indicated.
Evidence · text
“To upgrade part of the indicated resources to measured resources primarily in the western and central domains”
Step-Out Extensionpositive
Mineralization extended beyond the previously known limit.
Why it applies: Drilling at Challacollo aims to extend known veins down dip and along strike.
Evidence · text
“Investigate potential to expand the existing resource at Challacollo by extending some of known veins down dip and along strike”
NI 43-101 Compliantpositive
Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.
Why it applies: The Berenguela resource is described as a NI 43-101 mineral resource estimate.
Evidence · text
“A current NI 43-101 mineral resource estimate was published on December 4, 2025.”

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.
