# Bayhorse Silver - XRF Analysis of Bayhorse Silver Mine Flotation Concentrate Samples Shows Significant Contained Silver/Copper/Antimony/Zinc Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/bayhorse-silver-xrf-analysis-of-bayhorse-silver-mine-flotation-concentrate-sampl--03b79dcb-da56-41e4-b796-51c9b003ebe7 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: 2026-09-13 14:52:30 UTC Narrative sentiment: 0.40 · Bullish ## Minestarters Atlas summary Bayhorse Silver conducted XRF field analysis on flotation concentrate samples from its Oregon mine, showing high grades of silver, copper, antimony, and zinc. The company is sending samples to Allihies Engineering for proprietary antimony leaching tests to evaluate potential pilot-scale processing. Reasoning: XRF analysis of flotation concentrate shows high grades for Ag, Cu, Sb, and Zn, though results are unconfirmed by lab and the XRF unit was uncalibrated. The ore is noted as refractory. - Positive factor: High grade concentrate results - Positive factor: Potential for proprietary antimony leaching technology - Negative factor: XRF results unconfirmed by lab - Negative factor: XRF unit not recently calibrated - Negative factor: Refractory ore complexity - Negative factor: Samples not representative of run-of-mine material Low confidence — this extraction should be reviewed alongside the original source. 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 a field XRF unit on a 6.5kg sample, which is screening-level/preliminary. Evidence · text > field tested using the Company's Sci-Aps "X" series X-Ray Flourescence Unit \("XRF"\) **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: the document describes a flotation route \("flotation"\) **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: 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.
