# GR Silver Returns 5.34 g/t Gold From a Second San Marcial Target Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/gr-silver-returns-5-34-g-t-gold-from-a-second-san-marcial-target--e506a155-8554-4381-9705-3251c0cbd353 Original source: https://www.cruxinvestor.com/posts/gr-silver-returns-5-34-g-t-gold-from-a-second-san-marcial-target Publisher: cruxinvestor Original announcement: 2026-09-05T00:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: GR Silver Mining Ltd. - Ticker: GRSL - Exchange: Unavailable - Region: Mexico - Primary commodity: Silver - Secondary commodities: Gold, Lead, Zinc - Document categories: Drill results, Resource update - Extracted: 2026-09-05 19:18:08 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary GR Silver Mining reported step-out drill results from the San Marcial area of the Plomosas Project, extending the high-grade silver zone southeast of the 2023 resource boundary. Notably, the parallel breccia target returned gold intercepts, a metal previously assigned 0% recovery in the project's mineral resource estimate. Reasoning: Significant step-out results extending the silver resource and discovering new gold mineralization in a previously non-contributing target. - Positive factor: Step-out drilling extends high-grade silver zone 150m past 2023 resource boundary - Positive factor: Discovery of gold in parallel breccia target which was previously credited with 0% recovery - Positive factor: High-grade silver intercepts \(447 g/t\) in southeast extension - Positive factor: Presence of pathfinder elements \(Pb, Zn\) supporting geological model - Negative factor: Gold recovery in San Marcial area currently assumed at 0% in MRE Facts used in scoring: 12 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Drilling extended high-grade mineralization at least 150m past the 2023 resource boundary. Evidence · text > extending high-grade mineralization at least 150 m past the 2023 resource boundary **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 core goes to SGS de México for assay and silver results above 100ppm are re-assayed. Evidence · text > Core goes to SGS de México in Durango for assay, with silver results above 100 parts per million re-assayed. ## Extracted facts Stored fact records: 12.

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.
