Bayhorse Silver Inc Stock Price, News & Analysis

Bayhorse Silver (OTCQB: BHSIF) reported selective antimony leaching of ~99.9% from a concentrate containing 5.85% antimony using Allihies Engineering's proprietary process.

AMICS analysis identified the antimony as skinnerite (Cu3SbS3), a ~50/50 antimony-copper composite; concentrate grades were 5.79% copper and 10.53% zinc. The company says selective Sb removal could improve recoveries of silver, copper and zinc and is evaluating a pilot-scale leach facility at its Payette, Idaho mill.

The release includes a caution that no feasibility study supports production decisions and lists commodity, grade, cost and metallurgical risks.

Bayhorse Silver (OTCQB: BHSIF) will collect a 25-ton run-of-mine metallurgical bulk sample from three underground working faces across a 38 m vertical extent, 15.25 m width and 50 m strike to test silver, antimony, copper and zinc mineralization.

Samples will be crushed to minus 25 mm, ore-sorted with a Steinert KSS100 XRT, split into select/reject/fines, then milled and floated at the company's permitted Payette, Idaho flotation mill to determine grades, recoveries, tailings and wastewater needs under NI 43-101 standards.

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) submitted flotation concentrate samples from its Bayhorse Silver Mine (Oregon) to Allihies Engineering for testing with Allihies' proprietary Alkaline Selective Leaching (ASL) antimony process on October 16, 2025.

Allihies previously reported up to 99% antimony extraction on similar tetrahedrite mineralization. Bayhorse cites a 2018 inferred resource of 292,300 tons at 21.65 opt (6.3M oz Ag). A 2020 Ore-Sorter test produced a 5 kg concentrate with head grade 985 g/t Ag, 1.16% Cu, 1.87% Zn and achieved concentrate grades of 9,700 g/t Ag, 10% Cu, 18% Zn, 12% Sb with 86.7% recovery.

The company notes the material is refractory and not yet supported by a feasibility study; successful leaching could materially change payable-metal economics.

Bayhorse Silver (OTCQB: BHSIF) began mobilization for induced-polarization (IP) geophysical surveys at the Pegasus porphyry prospect and the Bayhorse Silver Mine in Oregon, commencing October 11, 2025.

The Pegasus IP will target a 1.6 km airborne VTEM low-resistivity anomaly with a reported vertical extent of at least 550 m. The Bayhorse IP expands prior coverage over the west side of the mine where drill hole WM2 returned very high-grade silver intervals (e.g., 1,104 g/t average over 1.5 m; 937 g/t average over 3 m). A 2020 metallurgical test reported 86.7% silver/copper recoveries and a concentrate grading ~9,700 g/t Ag and 10% Cu.

Bayhorse Silver (OTCQB: BHSIF) has appointed Christos Doulis to its Board of Directors. Doulis brings over 25 years of experience in metals and mining, having held key positions in mining equity research, investment banking, and industry leadership.

Doulis's background includes roles as a research analyst at Stonecap Securities and PI Financial, partnership at Gryphon Partners, and VP Investment Banking at TD Securities. He currently serves as CEO of Smooth Rock Ventures and is a board member of Grit Metals Corp.

Additionally, the company has granted 250,000 incentive stock options to directors, employees, and consultants, exercisable at $0.10 per share for five years.

Bayhorse Silver (OTCQB: BHSIF) has installed its Steinert Ore-Sorter at its 60 ton/day flotation mill in Payette, Idaho, following a 22-month rental period to Canadian Critical Minerals that generated approximately US$718,000 in rental revenue.

The Ore-Sorter effectively separates vein mineralization from host rock, reducing mined tonnage by up to 75%. The company's Bayhorse Mine contains tetrahedrite mineralization with historic grades reporting 21% between 20-100 oz/t silver and 73% between 6-20 oz/t silver. Metallurgical testing indicates concentrate grades of 7,500-12,000 g/t silver, 9-11% copper, 10-12% antimony, and 15-18% zinc.

The company is investigating the Allihies Alkaline Selective Leaching technology, which has demonstrated up to 99% leaching recovery for antimony separation, potentially enabling extraction of individual metals from its concentrate.

Bayhorse Silver (OTCQB: BHSIF) has completed its non-brokered private placement, raising $1,000,000 through the issuance of 25 million units. Each unit comprises one common share and one transferable warrant, exercisable at $0.06 per share for 24 months.

The proceeds will be allocated to: 48% for IP survey at Pegasus Project to identify drill targets, 31% for Bayhorse Mine permitting, and 21% for administrative expenses. The company will pay $38,640 in finder's fees and issue 966,000 finder's warrants. CEO Graeme O'Neill and CFO Rick Low participated in the placement, subscribing for 8,552,125 and 375,000 units respectively.

Bayhorse Silver (OTCQB: BHSIF) has renewed and expanded its silver/copper concentrate Offtake Agreement with Ocean Partners UK Ltd, increasing the proposed shipping volume to a minimum of 400 tons of silver/copper concentrate.

The company's permitted 50 ton/day flotation facility in Payette, Idaho, will process both company and third-party material. The Bayhorse Silver Mine is planned for up to 200 tons/day mining rate, with the KSS100 Ore-Sorter capable of upgrading silver content by removing over 75% of waste. Recent testing achieved 86.7% silver recovery, producing concentrate grades of 9,700 g/t silver.

A new discovery below current workings has led to plans for a 65-foot decline, targeting a zone with recent assays showing 1,103 g/t silver and 0.61% copper over 1.5m.
