# Rio Grande Resources Secures Historical North Star and Little Wonder Mines and Confirms Mineralization With Returned Samples of Up to 35.9 g/t Gold and 248 g/t Silver Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/rio-grande-resources-secures-historical-north-star-and-little-wonder-mines-and-c--3de962a7-3773-4b62-9bdb-279ce307def7 Original source: https://www.juniorminingnetwork.com/junior-miner-news/press-releases/3404-cse/rgr/212157-rio-grande-resources-secures-historical-north-star-and-little-wonder-mines-and-confirms-mineralization-with-returned-samples-of-up-to-35-9-g-t-gold-and-248-g-t-silver.html Publisher: jmn Original announcement: 2026-10-01T11:43:24.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-01T14:24:34.140Z Atlas analysis updated: 2026-10-01T14:24:34.140Z - Company: Rio Grande Resources Ltd. - Ticker: RGR - Exchange: CSE - Region: New Mexico - Primary commodity: Gold - Secondary commodities: Silver - Document categories: Drill results, Agreement transaction - Extracted: 2026-10-01 14:24:34 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Rio Grande Resources has expanded its Winston Gold-Silver Project in New Mexico by staking 26 additional claims covering the historical North Star and Little Wonder mines. Surface sampling from the recent Phase Two program and re-reported historical samples confirmed gold and silver mineralization, with gold grades up to 35.9 g/t. Reasoning: The company secured historical mine areas and confirmed mineralization with surface samples, including high-grade historical results being re-reported. - Positive factor: Confirmed mineralization in newly acquired historical mine areas - Positive factor: High-grade silver and gold intercepts in surface samples - Positive factor: Expansion of claim block to include prospective ground - Negative factor: No QA/QC duplicates or standards included in reconnaissance program - Negative factor: Historical results re-released without new assays Facts used in scoring: 20 ## 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 ALS Tucson is ISO/IEC 17025 accredited and uses fire assay and ICP-MS. Evidence · text > ALS Tucson is ISO/IEC 17025 accredited. **Stale Data Re-release** Polarity: negative Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty. Why it applies: The release includes results from a 2020 exploration program that were previously unreleased. Evidence · text > includes never released sample results from the Company's 2020 exploration program **Nearology Play** Polarity: neutral Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: The company is expanding claims to incorporate historical North Star and Little Wonder mines. Evidence · text > incorporating the historic North Star and Little Wonder mine areas ## Extracted facts Stored fact records: 20.

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.
