Bayhorse Silver Inc. reports exploration and development activity centered on the Bayhorse Silver Mine in Oregon and the adjacent Pegasus porphyry copper project in Idaho. Company updates commonly cover IP and AMT geophysical surveys, underground diamond drilling targets, NI 43-101 resource work, and metallurgical bulk samples from silver, antimony, copper, and zinc mineralization.
Recurring news also addresses mine operating-permit support work, groundwater and geochemical studies, ore sorting and flotation processing at the company's Payette mill, and capital actions such as warrant exercise programs. The coverage reflects a mineral issuer focused on resource definition, processing data, and project development disclosures.
Bayhorse Silver (BHSIF) reported that recent underground drilling expanded the known hydrothermal breccia zone at its Bayhorse Silver Mine.
Four recent holes, together with DDH2024-01, extend the zone to 160 m north–south and 180 m east–west, reaching 75–318 m below known workings. Assays are pending. Satellite analysis identified potential mineralized structures around Bayhorse and onto Pegasus, warranting further exploration.
The surface drilling permit applied for on February 20, 2026 remains pending, with no certain approval date; winter conditions may delay drilling. Surface drilling is needed to establish the northern zone's full extent and grade. The company expects its baseline study report for the mining permit application before year end.
Bayhorse Silver (BHSIF) has engaged Red Cloud Financial Services to provide media and marketing services, subject to TSX Venture Exchange acceptance.
The six-month engagement will commence on or after receipt of that acceptance. The total fee is $60,000, payable from working capital in monthly installments of $10,000. Red Cloud is at arm's length from Bayhorse and has no direct or indirect interest in the company or its securities, or any right or intent to acquire such an interest.
Bayhorse Silver (BHSIF) provides an operations update on its Bayhorse Silver Mine, where underground drilling and permitting work are advancing.
Six underground diamond drill holes totaling 2,750 ft have been completed, with a seventh in progress, and drill core is being submitted for assay on an ongoing basis. The company and independent consultant Haley & Aldritch are progressing the Bayhorse Mine Operating Permit and an application for up to 8 surface drill pad locations, which has been revised and resubmitted after regulator comments. A 25 ton bulk sample has been extracted, size‑segregated, sampled and submitted for assay and geochemical testing, which will support required baseline studies, including assessment of Ore-Sorter rejects for mine waste storage suitability.
Bayhorse Silver (OTCQB: BHSIF) reports that underground drilling at the Bayhorse Mine will recommence after a wildfire near Fox Creek, approximately 7 miles north of the mine, was contained and access restrictions were lifted late July 27, 2026.
According to Bayhorse Silver, CEO Graeme O'Neill inspected the access road and mine facilities and found no damage to infrastructure or equipment. The company had expanded the MSHA-required 100 ft non-flammable clearance around the mine portal to 200 ft, and the Ore-Sorter shelter’s non-flammable cover helped prevent fire damage. All personnel had been evacuated during the wildfire, and drilling operations are set to restart immediately.
Bayhorse Silver (OTCQB:BHSIF) has suspended underground drilling at the Bayhorse Silver Mine after a wildfire at Fox Creek, about 7 miles north of the site, expanded to over 45,000 acres by July 25 and triggered an evacuation order and access restrictions.
According to the company, it cannot yet determine wildfire impacts on mine facilities, though the site sits within 300 feet of the Brownlee Reservoir and reportedly has limited fuel. Prior to closure, new easterly drill holes had commenced, the crushing circuit was fully operational with bulk sample crushing started, and Bayhorse had received a John Deere 325 G skidsteer and a 45 ft by 25 ft metal core-shack building. The company plans to update operations once the evacuation order is lifted.
Bayhorse Silver (OTCQB:BHSIF) has completed underground drill preparations at the Bayhorse Silver Mine and will start a 2,000 m first-phase diamond drilling program on June 1.
The initial 13 holes will test CR-2 and easterly IP anomalies, targeting extensions of the 6.3 million-ounce NI 43-101 inferred silver resource.
Bayhorse Silver (OTCQB:BHSIF) has elected to adopt semi-annual financial reporting under Canadian Securities Administrators’ Coordinated Blanket Order 51-933 for certain venture issuers.
The company will stop filing Q1 and Q3 interim reports and MD&A, and instead file semi-annual and annual financial statements on its usual December 31 year-end schedule.
Bayhorse Silver (OTCQB: BHSIF) extracted an approved 25 ton run-of-mine metallurgical bulk sample from two working faces at the Bayhorse Silver Mine on April 7, 2026 to support NI-43-101 metallurgical testing and an operating permit application.
Samples reference high-grade historical assays (e.g., 1,642 g/t Ag and a weighted drill intersection of 1,140.68 g/t Ag). IP survey data indicate mineralization may extend to ~300 m vertical in places. Metallurgical work targets mill recoveries, flotation concentrate grades, antimony separation, and wastewater remediation planning.
Bayhorse Silver (OTCQB:BHSIF) increased its underground diamond drill program to up to 20 holes, with a first stage minimum of 2,300 m. The program targets IP anomalies CR-1, CR-2 and MW-2 and a second stage targeting CR-3, MR-1 and MR-2 east and below the inferred resource.
The company cites a NI 43-101 inferred resource of 292,300 tons at 21.65 opt (673 g/t) for 6.3 million ounces silver as the baseline to test potential expansion.
Bayhorse Silver (OTCQB: BHSIF) mobilized a diamond drill rig to the Bayhorse Silver Mine to begin up to 10 holes (2,000 m) of underground drilling, using a 2,500 ft depth-capable rig targeting IP anomalies CR-1, CR-2, CR-3, MR-1 and Deep-1.
The program expands the initial underground drilling from 1,000 m to 2,000 m and targets zones that extend beyond the company’s NI 43-101 inferred resource of 292,300 tons at 21.65 opt (673 g/t) for 6.3 million ounces silver, with prior intersections including very high-grade shallow samples up to 1,104 g/t.
