# Bayhorse Silver - XRF Analysis of Bayhorse Silver Mine Flotation Concentrate Samples Shows Significant Contained Silver/Copper/Antimony/Zinc Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/bayhorse-silver-xrf-analysis-of-bayhorse-silver-mine-flotation-concentrate-sampl--da3e41cd-09b2-40a6-a805-ef5f0137e42c Original source: https://money.tmx.com/en/quote/BHS/news/4666657164394537/bayhorse-silver-xrf-analysis-of-bayhorse-silver-mine-flotation-concentrate-sampl Publisher: tmx Original announcement: 2025-10-20T14:09:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Bayhorse Silver Inc - Ticker: BHS - Exchange: TSX - Region: Oregon, USA - Primary commodity: Silver - Secondary commodities: Copper, Antimony, Zinc, Lead - Document categories: Metallurgy - Extracted: 2026-08-21 05:17:55 UTC Narrative sentiment: 0.40 · Bullish ## Minestarters Atlas summary Bayhorse Silver conducted XRF field analysis on flotation concentrate samples from its mine in Oregon, showing high grades of silver, copper, antimony, and zinc. The company is pursuing metallurgical testing with Allihies Engineering to determine if proprietary antimony leaching can improve recoveries for these refractory minerals. Reasoning: The announcement reports high-grade flotation concentrate via XRF, but notes the ore is refractory and the XRF tool requires calibration and lab verification. - Positive factor: High grade concentrate results - Positive factor: Potential for antimony leaching technology - Negative factor: Refractory ore nature - Negative factor: XRF unit not recently calibrated - Negative factor: Results from development material, not ROM - Negative factor: XRF results require lab confirmation Facts used in scoring: 5 ## Classification and evidence **Refractory Ore** Polarity: negative Definition: Ore requires oxidation/pressure treatment before recovery — a processing and recovery risk. Why it applies: The document explicitly states the dominant mineralization is refractory in nature. Evidence · text > is refractory in nature **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: The analysis was conducted using field XRF on concentrate samples, which is a preliminary screening method. Evidence · text > XRF field analysis must be confirmed by lab analysis ## 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.
