# 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--4e7c21ea-42a3-44c3-a908-d38164f34933 Original source: https://orestocks.com/company/RGR.CN/press-releases/7095350032525804 Publisher: orestocks Original announcement: 2026-10-01T12:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-01T14:00:53.411Z Atlas analysis updated: 2026-10-01T14:00:53.411Z - Company: Rio Grande Resources Ltd. - Ticker: RGR.CN - Exchange: Unavailable - Region: New Mexico - Primary commodity: Gold - Secondary commodities: Silver - Document categories: Drill results, Other - Extracted: 2026-10-01 14:00:54 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. Recent surface sampling in the area returned gold and silver mineralization, including a historical sample of 35.9 g/t gold. Reasoning: The company secured historical mine ground and reported high-grade surface samples, though the lack of drilling and limited QA/QC \(no duplicates/standards\) limits certainty. - Positive factor: Expansion of claim block over historical mines - Positive factor: High-grade gold and silver surface samples - Positive factor: Structural continuity suggested between Poverty Creek and North Star - Negative factor: No QA/QC duplicates or standards included in reconnaissance program - Negative factor: Surface sampling only \(no drill intercepts yet\) Facts used in scoring: 8 ## Classification and evidence **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 release states no certified reference materials or duplicates were included due to the reconnaissance nature of the program. Evidence · text > No certified reference materials or duplicates were included **Stale Data Re-release** Polarity: negative Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty. Why it applies: The document re-announces 2020 sample results as part of the current news release. Evidence · text > includes never released sample results from the Company's 2020 exploration program ## 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.
