Reports: Initial Silver - Gold - Lead Recoveries of 85 %, 74 % and 77% Respectively From the Maria Norte in Central Peru Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/rio-silver-inc-reports-initial-silver-gold-lead-recoveries-of-85-74-and-77-respe--27ad6dc1-652c-4bd0-a702-5e78655f2892 Original source: https://money.tmx.com/en/quote/RYO/news/6417522979724236/rio-silver-inc-reports-initial-silver-gold-lead-recoveries-of-85-74-and-77-respe Publisher: tmx Original announcement: 2026-04-08T11:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Rio Silver Inc. - Ticker: RYO - Exchange: TSX - Region: Central Peru - Primary commodity: Silver - Secondary commodities: Gold, Lead - Document categories: Metallurgy - Extracted: 2026-09-12 22:57:39 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Rio Silver Inc. has reported successful initial metallurgical flotation test work at the Maria Norte property in Peru. The results demonstrated high recoveries for silver \(85%\), gold \(74%\), and lead \(77%\), producing two high-grade concentrates with low arsenic content. Reasoning: Initial flotation test work on a large composite sample from Maria Norte shows strong recoveries for silver, gold, and lead with low arsenic penalties. - Positive factor: High silver and gold recoveries achieved via flotation - Positive factor: Low arsenic levels in concentrates - Positive factor: High-grade concentrates produced - Negative factor: Initial test work only; further optimization required for different vein sets Facts used in scoring: 3 ## Classification and evidence **Free Milling** Polarity: positive Definition: Simple, clean ore amenable to standard processing without oxidation. Why it applies: Initial flotation results show good recoveries for silver, gold, and lead. Evidence · text > Initial metallurgical results have confirmed the high recoveries of silver and gold at Maria Norte. **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The metallurgical work utilized conventional flotation methods. Evidence · text > through conventional flotation methods **Single Domain Only** Polarity: negative Definition: Testing limited to one composite or domain — representativeness not established. Why it applies: only one composite was tested ## Extracted facts Stored fact records: 3.

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.
