# Bayhorse Silver Submits Silver/Copper/Antimony Concentrate Samples From Its Bayhorse Silver Mine To Allihies Engineering For Antimony Leach Testing Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/bayhorse-silver-submits-silver-copper-antimony-concentrate-samples-from-its-bayh--c6b5f884-5bf8-4d63-a03f-e55c65cc7c84 Original source: https://money.tmx.com/en/quote/BHS/news/4674203318340748/bayhorse-silver-submits-silver-copper-antimony-concentrate-samples-from-its-bayh Publisher: tmx Original announcement: 2025-10-16T14:46:00.000Z 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, Gold, Lead - Document categories: Metallurgy, Other - Extracted: 2026-09-13 14:51:13 UTC Narrative sentiment: 0.40 · Bullish ## Minestarters Atlas summary Bayhorse Silver has submitted flotation concentrate samples from its Bayhorse Silver Mine to Allihies Engineering for proprietary antimony leaching testing. The testing aims to determine if the company's refractory silver-copper-antimony mineralization can be processed more effectively than previous methods, potentially unlocking significant value from critical minerals. Reasoning: The company is testing a new hydrometallurgical route to address refractory mineralization, which could significantly improve recoveries and economic viability of the silver-copper-antimony project. - Positive factor: Potential to unlock value from refractory antimony/silver/copper/zinc mineralization - Positive factor: Proprietary leaching technology \(ASL\) shows high extraction rates \(99% Sb\) in similar deposits - Positive factor: Strategic/critical mineral status for all target metals in the US - Positive factor: Potential to significantly improve historical cost-benefit calculations - Negative factor: Mineralization is refractory in nature, presenting processing challenges - Negative factor: Metallurgical testing is currently in the sample submission stage, results are not yet confirmed for this specific site - Negative factor: Refractory processing typically requires higher energy inputs Facts used in scoring: 4 ## 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 > The dominant Bayhorse mineralization is primarily tetrahedrite... and is refractory in nature. **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The company mentions a permitted mill in Payette, Idaho and standard flotation processing. Evidence · text > to ship to our permitted Mill in Payette, Idaho... and standard flotation processing facility **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: 4.

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.
