Summary

Tier One Silver has announced high-grade silver and gold intercepts from its Phase 2 drilling at the Curibaya project in Peru. Highlights include a 1.0m interval of 448.2 g/t Ag and 0.37 g/t Au in hole 26CUR-023, contributing to an expanded 6 km mineralized footprint.

Reasoning: The release reports several high-grade silver intercepts, including a 448.2 g/t Ag sub-interval, which expands the known mineralized footprint and confirms continuity in the Cambaya I corridor.

Positive factors

  • high-grade silver intercepts
  • expansion of mineralized footprint
  • continuity of mineralization

Negative factors

  • true widths unknown

Facts used in scoring: 32

Classification and evidence

QA/QC Disclosedpositive

Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).

Why it applies: Release mentions use of company and lab duplicates, standards, and blanks.

Evidence · text

“QA/QC programs for 2026 core samples using company and lab duplicates, standards and blanks indicate good accuracy and precision.”

Apparent Width Onlynegative

Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Why it applies: The document explicitly states that true widths of mineralization are unknown.

Evidence · text

“True widths of mineralization are unknown based on current geometric understanding of the mineralized intervals.”

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.
