# GR Silver Confirms Extension of Mineralization at San Marcial, Including 16.1 m at 162 g/t Ag and 11.7 m at 147 g/t Ag in the SE Area Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/gr-silver-confirms-extension-of-mineralization-at-san-marcial-including-16-1-m-a--109afc7e-79af-407e-ada6-71a0d9f5d995 Original source: https://finance.yahoo.com/markets/commodities/articles/gr-silver-confirms-extension-mineralization-110000056.html Publisher: yahoo\_press Original announcement: 2026-09-08T11:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: GR Silver Mining Ltd. - Ticker: GRSL - Exchange: TSXV - Region: Mexico - Primary commodity: Silver - Secondary commodities: None reported - Document categories: Drill results - Extracted: 2026-09-10 20:03:05 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary GR Silver Mining has reported significant silver drill intercepts at its San Marcial project in Mexico. The results confirm the extension of mineralization beyond the boundaries of the 2023 NI 43-101 Mineral Resource Estimate. Reasoning: The announcement confirms the extension of mineralization beyond the previously reported 2023 MRE area with notable silver intercepts. - Positive factor: extension of mineralization - Positive factor: significant drill intercepts Facts used in scoring: 2 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The release explicitly states the results confirm extension of mineralization beyond the 2023 MRE area. Evidence · text > confirming extension of mineralization beyond the 2023 NI 43-101 Mineral Resource Estimate \("MRE"\) resource area **No QA/QC Disclosure** Polarity: negative Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document. Why it applies: The document does not disclose assay protocols, lab certification, or QP sign-off.

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.
