Vancouver, British Columbia--(Newsfile Corp. - September 23, 2025) - Bayhorse Silver Inc (TSXV: BHS) (OTCQB: BHSIF) (FSE: 7KXN) (the "Company" or "Bayhorse") reports that the Company's Steinter Ore-Sorter ("Sorter") has been returned from its 22 month rental to Canadian Critical Minerals Inc ("Critical") and has been installed at the Company's 60 ton/day flotation mill in Payette, Idaho.
During the rental period, Critical relied upon the Sorter to generate revenue from upgrading their existing 180,000 ton copper/silver/gold stockpile at its Bull River Mine to a preconcentrate that was then shipped to the New Afton Mill for processing. The Company has received gross rental revenue totaling approximately US$718,000 from the rental to Critical.
The Company has opted to install the Sorter at its Mill so it can be used for third party processing and potential revenue generation while the Bayhorse Mine permitting is completed.
The Bayhorse Silver Mine mineralization is primarily tetrahedrite, which is an antimony sulfide of silver, copper, iron and zinc in veins and stockworks with minor gold present. Using its Ore-Sorter, the Company has conducted significant testing, and found it very effectively separates the vein mineralization from the surrounding rhyolite/andesite host rock, reducing the mined tonnage by as much as 75% or more, depending upon grade. During its 1984 mining program, Silver King Mines reported 21% of the Bayhorse mined grades were from 20 oz/t to 100 oz/t, 73% of the mined grades were between 6 oz/t and 20 oz/t, with 6% being under 6 oz/t, that was the cut off grade at that time. Up to 10 g/t gold was also reported by Silver King Mines. The Company is using these historic averages as a guide in its mining program when permitted (BHS2022-05).
The tetrahedrite, which is refractory in nature, is to be processed at the Company's 60 ton/day flotation mill. Metallurgical testing of the Bayhorse mineralization by Metsolve Labs, Langley, BC, has indicated a typical concentrate will range between 7,500-12,000 g/t silver 9-11% copper, 10-12% antimony and 15-18% zinc. With silver now added to copper, antimony and zinc as "critical minerals" in the United States by the United States Geological Service, the Company has been researching means to separate each of the minerals from its flotation concentrate as value added extras, especially antimony, as a 55% concentrate is currently quoted at US$8.51/lb on the Shanghai Metals Exchange.

Recent news from America's Gold and Silver, (AGS) Galena Mine in Idaho's "Silver Valley" which has similar "tetrahedrite" (silver, copper, antimony) mineralization to the Bayhorse Silver Mine, has reported that after submitting their mineralization to SGS Laboratories for metallurgical testing for optimum recoveries, the tests showed significant recoveries of silver/antimony/copper. The subsequent flotation concentrate was leached by Allihies Engineering Inc. ("Allihies") using its proprietary, selective industrial Alkaline Selective Leaching ("ASL") hydrometallurgical technology, that confirmed very high extraction rates of antimony are possible.
The Company is investigating the Allihies process to see if it can be incorporated into its Mill to extract the silver/antimony/copper/zinc from its flotation concentrate and unlock their individual values.
Bayhorse CEO Graeme O'Neill comments, "The Company has conducted significant research into using the "Sunshine Leaching Process" that was used at the historic Sunshine Silver Mine, Kellogg, Idaho that reportedly achieved antimony leach separation recoveries of up to 87%, however, Allihies confirms up to 99% leaching recovery using its proprietary, selective industrial ASL hydrometallurgical technology. Once the antimony is leached from the tetrahedrite, the gold, silver, copper, and zinc becomes available for refining into their pure metal form."
Cautionary statement
The Company is not basing any decision to produce on a feasibility study of mineral reserves demonstrating economic and technical viability and advises there is an increased uncertainty and specific economic and technical risk of failure with any production decision. These risks include, but are not limited to, (i) a drop in price of commodities produced, namely silver, copper, lead and zinc, from the pricing used to make a production decision; (ii) failure of grades of the produced material to fall within the parameters used to make the production decision; (iii) an increase in mining costs due to changes within the mine during development and mining procedures; and (iv) metallurgical recovery changes that cannot be anticipated at the time of production.
