Bayhorse Silver - XRF Analysis of Bayhorse Silver Mine Flotation Concentrate Samples Shows Significant Contained Silver/Copper/Antimony/Zinc
Bayhorse Silver (OTCQB:BHSIF) reported XRF field analysis of a 6.5 kg split from a 20 kg sample taken from a 7-tonne flotation concentrate stockpile at the Bayhorse Mill on October 20, 2025. Four XRF readings averaged Ag 135 oz/t, Cu 20.6%, Sb 19.5%, and Zn 40.3%. The company holds 22 tons of flotation concentrate and plans further milling on ~100 tons of sorted development material.
Bayhorse sent a 5.5 kg concentrate sample to Allihies for ASL leach testing and a 0.5 kg sample to Paragon Laboratory for full metals analysis. The release notes the XRF unit was not recently calibrated and that XRF results must be confirmed by lab testing; ICP analysis is not advised due to extremely high grades.
Bayhorse Silver (OTCQB:BHSIF) ha riportato l'analisi XRF sul campo di una divisione di 6,5 kg da un campione da 20 kg estratto da una pila di stock di concentrate da flottazione da 7 tonnellate presso Bayhorse Mill il 20 ottobre 2025. Quattro letture XRF hanno mediato Ag 135 oz/t, Cu 20,6%, Sb 19,5% e Zn 40,3%. L'azienda possiede 22 tonnellate di concentrate da flottazione e prevede ulteriori macinazioni su circa ~100 tonnellate di materiale di sviluppo ordinato.
Bayhorse ha inviato un campione di concentrato di 5,5 kg a Allihies per i test di leach ASL e un campione da 0,5 kg al Paragon Laboratory per un'analisi completa dei metalli. Il comunicato sottolinea che l'unità XRF non è stata recentemente calibrata e che i risultati XRF devono essere confermati da analisi di laboratorio; non è consigliata l'analisi ICP a causa degli estremi livelli di concentrazione.

Vancouver, British Columbia--(Newsfile Corp. - October 20, 2025) - Bayhorse Silver Inc, (TSXV: BHS) (OTCQB: BHSIF) (FSE: 7KXN) (the "Company" or "Bayhorse") has conducted an XRF field analysis of the Bayhorse flotation concentrate samples from its silver-copper-antimony-zinc rich Bayhorse Silver Mine in Oregon, USA recently sent to Allihies Engineering Inc. ("Allihies"), Montana, for testing using Allihies's proprietary Antimony leaching technology.
A 20 kg sample was taken from three (3) locations within one seven (7) tonne (7.5 ton) flotation concentrate stockpile at the Bayhorse Mill, of which a 6.5 kg (14.3lb) sample was field tested using the Company's Sci-Aps "X" series X-Ray Flourescence Unit ("XRF") and separated into three (3) separate samples. One 5.5kg (12lb) was sent to Allihies, one 0.5 kg (1.1lb) sample was submitted to Paragon Laboratory for full metals analysis, including sulphur content, to compare to the XRF field analysis, and one reference 0.5 kg sample that is kept at the Bayhorse Mill.
Four XRF field analyses measurements were taken of the 6.5 kg samples in order to get a representative analysis and are reported in the table below.
| Average | |||||||||
| Ag oz/t | 75 | 68 | 166 | 231 | 135 | ||||
| Cu % | |||||||||
| Sb % | |||||||||
| Zn % | |||||||||
| Pb % |
*Note: XRF field analysis must be confirmed by lab analysis. Due to extremely high grades the XRF showed in the flotation con, ICP analysis is not advised. The XRF unit .has not been recently calibrated which is why multiple comparison tests were required.
The Company has 22 tons of flotation concentrate derived from sorting and milling Bayhorse underground development material and setting up the Payette, Idaho, flotation mill. Development material was derived from installing new workings prior to 2019, including 750ft of bolted and screened haulage way to access the historic mineralized zones, a 250 ft secondary escape way, and 300 ft of drifts and raises to safely access historic workings, as well as cleaning up historic mined stopes and establishing working faces in preparation for mining. The development material is not run of mine and is of variable grade and is not representative of what can be expected of mining developed stopes.
Bayhorse CEO, Graeme O'Neill, comments "while the sampling was conducted on Mine development material, and not representative of what we will actually be mining, we were very pleasantly surprised at the percentages of copper, antimony, and zinc recovery in the concentrate along with the silver. We have another 100 tons of sorted Mine development material to mill and float, and will look forward to the leach testing results to determine whether we can install a pilot leaching system at the Bayhorse Mill so all the metals become payable."
When mining is permitted, the mineralised "run of mine" material mined at the Bayhorse Mine will be crushed to 1 inch minus (25 mm) and then fed through our Steinert ore sorter where roughly
Allihies using its proprietary, selective industrial Alkaline Selective Leaching ("ASL") hydrometallurgical technology, recently conducted leaching tests on America's Gold and Silver, flotation concentrate from its Galena Mine in Idaho's "Silver Valley" which has similar "tetrahedrite" (silver, copper, antimony zinc) mineralization to the Bayhorse Silver Mine. The leaching tests confirmed very high extraction rates of up to
The dominant Bayhorse mineralization is primarily tetrahedrite, (BHS2020-12) an antimony sulfide of silver, copper, zinc and iron in veins and stockworks with minor gold present, and is refractory in nature.
Extracting the silver from refractory minerals presents several challenges as the complex mineral structures often leads to lower recovery rates compared to free-milling minerals. Processing refractory minerals also requires high energy inputs, making it cost-prohibitive in some cases. Leaching permits the cost-effective separation of the antimony and sulphur and significantly increases recoveries of the silver, copper and zinc for processing separately.
The silver, antimony, copper and zinc at the Bayhorse Silver Mine are all recognized as both "critical and strategic minerals" in the United States.
The Bayhorse exploration model holds that the silver-copper-antimony rich mineralization at the Bayhorse Silver Mine extends across to the adjacent Pegasus porphyry copper prospect and could have its source in an underlying shallow pluton(s) that may host porphyry copper mineralization similar to what Hercules Metals has reported 40 km north of the Bayhorse Silver Mine.
