# Rio Silver Highlights High-Grade Silver up to 6.26 g/t Au and 991 g/t Ag \(28.9 oz per metric tonne\) over 0.70 metres at Maria Norte and Advances a Clear Near-Term Development Path in Peru Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/rio-silver-highlights-high-grade-silver-up-to-6-26-g-t-au-and-991-g-t-ag-28-9-oz--574cfb4f-21d4-4643-9412-a54bdfca85d8 Original source: https://money.tmx.com/en/quote/RYO/news/5414459072026036/rio-silver-highlights-high-grade-silver-up-to-6-26-g-t-au-and-991-g-t-ag-28-9-oz Publisher: tmx Original announcement: 2026-01-06T12:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Rio Silver Inc. - Ticker: RYO - Exchange: TSX - Region: Peru - Primary commodity: Silver - Secondary commodities: Gold, Lead, Zinc, Copper - Document categories: Drill results, Metallurgy - Extracted: 2026-08-21 03:35:27 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Rio Silver has confirmed high-grade silver and gold mineralization at the Maria Norte project in Peru through NI 43-101 verification sampling. The results include silver grades up to 991 g/t and gold up to 6.26 g/t, supported by favorable metallurgical indications for flotation. Reasoning: Verification sampling confirms high-grade silver \(up to 991 g/t\) and gold \(up to 6.26 g/t\) at surface, supporting the project's epithermal model. - Positive factor: High-grade silver intercepts confirmed via NI 43-101 verification - Positive factor: Favorable metallurgy \(flotation amenability\) noted - Positive factor: Proximity to existing infrastructure - Negative factor: No QA/QC \(blanks/standards\) inserted due to low sample count Facts used in scoring: 5 ## 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 samples were bagged, labelled, and sealed, and analyzed by Certimin S.A., an ISO 9001-certified lab. Evidence · text > All samples were bagged, labelled, and sealed in the field using single-use security ties... analyzed by Certimin S.A., an ISO 9001–certified laboratory **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 author explicitly states no blanks, standards, or duplicates were inserted due to limited sample size. Evidence · text > No additional quality control samples \(blanks, standards, or duplicates\) were inserted due to the limited number of samples collected ## Extracted facts Stored fact records: 5.

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.
