Bayhorse Silver Reports Significant IP Results From The Bayhorse Silver Mine

Rhea-AI Summary

Bayhorse Silver (OTCQB: BHSIF) announced results from an induced polarisation (IP) survey over the Bayhorse Silver Mine property, Oregon, completed January 2026. The 50 m depth slice highlights low-resistivity zones that coincide with known mineralization and expand mineralized footprints to at least 1,000 m north-south and >914 m east-west, with a minimum vertical extent of 110 m. Three localized low-resistivity zones (CR1–CR3) and five resistivity lineaments (LR1–LR5) were mapped, showing spatial ties to mapped faults. A groundwater test well (MW2) intersected high-grade intervals including 1.5 m at 1,104 g/t Ag and 1.5 m at 770 g/t Ag. The results will guide upcoming surface and underground drilling aimed at potentially converting inferred ounces within the NI 43-101 resource (6.3 Moz Ag) to indicated.

Positive

• Enlarged footprint: mineralized zone extends minimum 1,000 m north-south
• High-grade intercepts: MW2 shows 1.5 m at 1,104 g/t Ag and 1.5 m at 770 g/t Ag
• Depth continuity: mapped mineralization spans at least 110 m vertically

Negative

• Localized features: CR1–CR3 are laterally confined with limited vertical extent
• Edge uncertainty: CR3 geometry is poorly constrained due to proximity to grid edge

Vancouver, British Columbia--(Newsfile Corp. - January 21, 2026) - Bayhorse Silver Inc, (TSXV: BHS) (OTCQB: BHSIF) (FSE: 7KXN) (the "Company" or "Bayhorse") is pleased to announce the IP Survey results over its Bayhorse Silver Mine Property, Oregon, USA, that commenced in October 2025 and was completed in January 2026. These results will better guide both the surface and underground drilling programs as previously outlined in BHS2026-02.

Bayhorse CEO Graeme O'Neill, who along with the Company's Directors, will be attending the upcoming Vancouver Resource Investment Conference and the Cordilleran Roundup, comments, "We are very encouraged to have received the results of the IP survey undertaken at the Bayhorse Mine. The IP results, specifically the low resistivity areas in blue, that in the Bayhorse coincide with known mineralization, has significantly expanded the known mineralized zones and provided more drill targets over a wider area that will better guide both our surface our underground drilling programs that will commence shortly. The objective of these programs is to further refine our understanding of the extent, structure and mineralization of the Bayhorse silver endowment and to increase inferred ounces to our National Instrument 43-101 Mineral Resource Estimate of 292,300 tons at a grade of 21.65 opt (673 g/t) for 6.3 million ounces of silver. (Turner et al. 2018) and to determine whether inferred ounces can be brought to an indicated category."

The IP low resistivity depth slice shown in Figure 1 lies 50 m (165 ft) below the surface and encompasses an area of over 914 m (3,000 ft) from east to west. The top of the Goldilocks zone in the extreme west of the main historic workings that were developed in 1984, lies at least 46 m (150 ft) below the IP depth slice shown in Figure 1 indicating a minimum110 m (350 foot) vertical mineralized extent, with the now enlarged zone extending a minimum 1,000 m (3,280 ft) from north to south.

Five prominent resistivity lineaments (LR1-LR5) (dotted black lines) are identified, including three trending NNW and two trending NNE to near north-south. When overlain with interpreted geology these lineaments show spatial correspondence with mapped faults (mineralized Sunshine, Railroad faults etc) and lithological contacts.

Three localized low-resistivity features CR1, CR2 and CR3 have been identified adjacent to lineament LR1. These features are laterally confined and exhibit limited vertical extent. The upper portion of CR1 coincides with the underground mine adits and workings and forms a sub-vertical feature dipping north. CR2 lies approximately 200 m southeast of CR1 and is smaller in size. Both CR1 and CR2 occur beneath a shallow resistive (pink) layer. CR3, located near the northwestern end of LR1, is elongated north-south and dips slightly west; its geometry is less well constrained due to proximity to the grid edge.

The IP results also indicate that the surface drill targets outlined by prior IP results (BHS2025-05). immediately to the east of the NI 43-101 compliant inferred resource appears to be far more extensive than initially believed. These targets lie under the Mine access road and extend from 73 m (240 ft) east of and up 130 m (426 ft) north of the inferred resource. One of these targets was intersected by groundwater test well MW2 at a depth of between 22 m and 33.5 m (72 -110 ft) from surface with a 3 m (10 ft) intersection of 1.5 m (5 ft) grading an average of 1104 g/t (35.46 opt) silver and 1.5 m (5 ft) averaging 770 g/t (23.12 opt) silver. This intersection lies at an elevation of 667 m (2190 ft) above sea level ("ASL") and 91 m (300 ft) NE and 60 m (200 ft) lower than the historic, mined, Sunshine Stope at an elevation of 728 m (2390 ft) ASL.
