# Tier One Silver Commences Phase 2 Drilling at High-Grade Curibaya Project in Peru Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/tier-one-silver-commences-phase-2-drilling-at-high-grade-curibaya-project-in-per--77d67b8b-bb0d-4d54-bd5a-6aa57949021a Original source: https://money.tmx.com/en/quote/TSLV/news/4585287841092395/tier-one-silver-commences-phase-2-drilling-at-high-grade-curibaya-project-in-per Publisher: tmx Original announcement: 2026-02-18T12:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Tier One Silver Inc. - Ticker: TSLV - Exchange: TSX - Region: Peru - Primary commodity: Silver - Secondary commodities: Gold, Copper - Document categories: Drill results, Other - Extracted: 2026-08-24 06:56:25 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Tier One Silver has commenced Phase 2 drilling at its Curibaya project in Peru, targeting the undrilled Cambaya 1 corridor. The program will test beneath high-grade silver-gold channel samples to evaluate vertical continuity and system scale. Reasoning: The announcement details the commencement of a new drilling phase targeting high-grade silver-gold mineralization identified via surface sampling. While no new assay results are reported, the targets are high-grade and represent an undrilled portion of the system. - Positive factor: high-grade channel samples target - Positive factor: undrilled high-level corridor - Positive factor: QA/QC disclosed - Negative factor: true width unknown Facts used in scoring: 18 ## Classification and evidence **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: Release mentions internal standards, blanks, and duplicates for both channel and drill samples. Evidence · text > QA/QC programs for channel samples using internal standard and blank samples; field and lab duplicates indicate good overall accuracy and precision. **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: Multiple silver intercepts exceed 500 g/t, with some reaching 2680 g/t. Evidence · text > including 1 m of 2,680 g/t Ag **Apparent Width Only** Polarity: negative Definition: 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 due to unknown orientation. Evidence · text > True widths of mineralization are unknown due to the unknown mineralized zones orientation. ## 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.
