Bayhorse Silver (BHSIF) renewed its silver/copper concentrate Offtake Agreement with Ocean Partners, increasing the shipping volume to 400 tons. Bayhorse plans to process company and third-party material at its Payette, Idaho facility. Mining rate expansion to 200 tons/day is planned, utilizing ore-sorting technology for silver content upgrades. A new mineralized zone was discovered with high-grade silver assays, prompting the planning of a 65-foot decline. While promising, a feasibility study of mineral reserves is still needed for the production decision.
Bayhorse Silver (OTCQB: BHSIF) is making headlines with the renewal and expansion of its silver/copper concentrate Offtake Agreement with Ocean Partners UK Ltd. The deal now includes a commitment to ship a minimum of 400 tons of silver/copper concentrate, showcasing increased confidence in Bayhorse’s production capabilities.
The company’s Payette, Idaho, facility, permitted for 50 tons per day, is slated to process both company-sourced and third-party materials. Bayhorse Silver Mine is gearing up for a mining rate of up to 200 tons per day, leveraging its KSS100 Ore-Sorter. This technology is expected to significantly upgrade silver content by removing over 75% of waste. Recent testing has been promising, achieving an 86.7% silver recovery rate and producing concentrates with silver grades hitting 9,700 g/t.
Adding to the momentum, a new discovery below current workings has spurred plans for a 65-foot decline. This move aims to tap into a mineralized zone where recent assays revealed impressive grades of 1,103 g/t silver and 0.61% copper over 1.5 meters.

Vancouver, British Columbia — Bayhorse Silver Inc. (TSXV: BHS) (OTCQB: BHSIF) (FSE: 7KXN) (“Bayhorse” or the “Company”) is pleased to announce the renewal of its silver/copper concentrate Offtake Agreement with Ocean Partners UK Ltd, coupled with an increase in the proposed concentrate shipping volume to a minimum of 400 tons of silver/copper concentrate.
The agreement allows for the inclusion of third-party material, and the Company is now actively seeking such mineralized material for processing at its permitted 50 ton/day flotation facility in Payette, Idaho. Previous assessments suggest the potential to produce a minimum of 2 tons per day of flotation silver concentrate, containing up to 10% copper, 12% antimony, and 18% zinc, along with silver.
Graeme O’Neill, CEO of Bayhorse, stated, “The Bayhorse Silver Mine has plans for a mining rate of up to 200 tons/day. Depending on the mined grade, the company’s KSS100 Ore-Sorter can upgrade the mined tonnage silver content a minimum 4 times by removing over 75% of non-mineralized waste from the mining stream to produce a preconcentrate of between 20 to 50 tons/day, for shipping to its flotation mill. The mineralization at the Bayhorse site includes significant quantities of copper, antimony, zinc, and lead, alongside trace amounts of gold. Testing that sent a 5 kg Ore-Sorter select sample with a head grade of 985 g/t (28.8 oz/t) silver, 1.16% copper and 1.87% zinc, was derived from a 200 kg mined sample that was passed through the Ore-Sorter, that reduces the volume of lower grade mineralization by between 80% to 95%. The flotation silver concentrate recoveries yielded 86.7% silver, resulting in a silver grade of 9,700 g/t. The predominant mineralization at the Bayhorse mine is Tetrahedrite.”
The discovery of promising new mineralized zones beneath the current workings is prompting a review of the existing mine plan and permit application. A new 65-foot decline is planned beneath the existing mine road to intersect the west to east zone. This zone is estimated to be nearly 140 ft long with a width of 70-80 foot and a 35 ft thickness, with 3 m (10 foot intersection averaging 1103 g/t (35.46 oz/t) silver and 0.61% copper over 1.5 m (5 ft) and 23.12 silver over 1.5m (5 ft) for an average grade of 911 g/t (29.29 opt) over 3 m (10ft).
The planned decline will also provide access to two other prospective IP targets located 76 m (250 feet) north of this new zone. Along with existing underground development, the new zone will allow up to three working faces to attain the planned 200 tpd throughput. Mining costs are updated quarterly by the company in relation to other mine costs to ensure that mine planning can be realized.

Analysts caution that the company is not basing any production decision on a feasibility study of mineral reserves demonstrating economic and technical viability. Therefore, there is increased uncertainty and economic and technical risk of failure with any production decision. These risks include drops in commodity prices (silver, copper, lead, and zinc), failure of produced material grades to meet expectations, increased mining costs, and unanticipated metallurgical recovery changes.
In essence, while progress is being made, the firm needs a feasibility study of mineral reserves demonstrating economic and technical viability. The company notes potential risks related to changes within the mine during development; changes in production procedures; and any metallurgical recovery changes that cannot be realistically anticipated at the time of production.
