# Defiance Silver Drilling Returns up to 356 g/t Ag and 2.15 g/t Au in Additional Silver and Gold Structures Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/defiance-silver-drilling-returns-up-to-356-g-t-ag-and-2-15-g-t-au-in-additional--06ea79c6-6c20-4f32-9b0a-13c1608ab599 Original source: https://money.tmx.com/en/quote/DEF/news/6064690680093288/defiance-silver-drilling-returns-up-to-356-g-t-ag-and-2-15-g-t-au-in-additional- Publisher: tmx Original announcement: 2026-05-11T05:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Defiance Silver Corp. - Ticker: DEF - Exchange: TSX - Region: Zacatecas, Mexico - Primary commodity: Silver - Secondary commodities: Gold - Document categories: Drill results, Resource update - Extracted: 2026-09-15 18:51:30 UTC Narrative sentiment: 0.70 · Bullish ## Minestarters Atlas summary Defiance Silver Corp. reported drill results from its Zacatecas Project, featuring silver grades up to 543 g/t Ag. The drilling, part of a 10,000m program, aims to confirm structural extensions and validate the geological model for an upcoming Mineral Resource Estimate. Reasoning: Strong silver grades reported in several holes, including a high-grade sub-interval of 543 g/t Ag. Results confirm historical mineralization and support upcoming resource estimate. - Positive factor: High-grade silver intercepts - Positive factor: Confirmation of historical mineralization - Positive factor: QA/QC protocols disclosed - Negative factor: Apparent width only \(true width not explicitly stated for all intercepts\) Facts used in scoring: 8 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: 0.26m at 543 g/t Ag is an exceptionally high-grade zone. Evidence · text > 0.26m of 543.00 g/t Ag **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 includes details on blanks, standards, and duplicates used with ALS Chemex. Evidence · text > One blank, one standard, and one duplicate were included within every 20 samples. **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: True thickness is not explicitly stated for the reported intercepts, only assumed to be 50-80% of downhole width. Evidence · text > True thickness is assumed to be 50% - 80% of downhole width. ## Extracted facts Stored fact records: 8.

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.
