Bayhorse Silver Installs Its Steinert Ore-Sorter At Its Bayhorse Flotation Mill, Payette, Idaho, USA

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.
