Bayhorse Silver Inc. (TSXV: BHS | OTCQB: BHSIF | FSE: 7KXN) has released an operations update on its Bayhorse Silver Mine in Oregon, confirming that underground diamond drilling is continuing despite recent wildfire-related delays. The company reports six drill holes totalling 2,750 feet have been completed, with a seventh underway, and drill core is being submitted for assay on an ongoing basis. The update also covers progress on the Mine Operating Permit application and the status of the bulk sample program, which investors may be watching closely for early grade indicators.

Key Points

  • Bayhorse Silver Inc. (TSXV: BHS | OTCQB: BHSIF | FSE: 7KXN) operates the Bayhorse Silver Mine in Oregon, USA.
  • Six underground diamond drill holes totalling 2,750 feet have been completed, with a seventh in progress; assay results will be released as received.
  • The company's permitted 25-ton bulk sample has been pre-screened, crushed, and submitted for assay by independent consultant Haley & Aldrich, Inc.
  • Investors should watch for assay results from both the drilling program and bulk sample, and for progress on the surface drilling permit application.

Underground Drilling Advances at Bayhorse Silver Mine Despite Wildfire Disruptions

Bayhorse Silver confirmed that underground drilling operations are continuing at the Bayhorse Silver Mine, with six diamond drill holes totalling 2,750 feet completed to date and a seventh hole underway. The company attributed delays to recent wildfires in the vicinity of the mine, as well as logistical challenges associated with drilling from underground. Drill core is being submitted to an assay laboratory on an ongoing basis, with results to be disclosed as they are received. The immediate share price impact was not clear from available public information.

Surface Drill Permit Application Resubmitted to Oregon Regulator

Bayhorse is working with independent technical consultant Haley & Aldrich, Inc. ("H&A") on the permitting process for up to eight proposed surface drill pad locations. The application, initially submitted to the Oregon Department of Geology and Mineral Industries (DOGAMI) in March of this year, has only recently begun being processed due to high application volumes received by the regulator. Following a request for amendments to the paperwork, a revised application has been resubmitted for approval. The surface drilling program is targeting an area 136 m north of the mine portal, where a previous groundwater test intersection graded an average of 29.29 ounces per ton silver.

Bulk Sample Processing and Operating Permit Groundwater Testing Under Way

The company has extracted its permitted 25-ton bulk sample, pre-screened to separate minus and plus 8 mm fractions. H&A has collected samples from the run-of-mine material, fines, and plus 8 mm fractions, all submitted for assay. Geochemical testing of the bulk sample will form part of the required baseline study for the Operating Permit application, which targets mining and dry processing through the company's 40-ton-per-hour Steinert Ore-Sorter. A groundwater testing program requiring four tests over 12 months is also progressing, with the first test conducted in January and the fourth scheduled for the end of 2026.

Ore-Sorter Reject Suitability and Acid-Base Assessment Planned

H&A will conduct Acid-Base Assessment ("ABA") testing on Ore-Sorter rejects to independently verify the company's own testing, which indicates an ABA result of plus 29 — suggesting significant acid-reducing potential. The company states this would mean rejects are unlikely to produce acid rock drainage and may be suitable for underground and above-ground mine waste storage. The release also notes that Ore-Sorter rejects are not classified as tailings. The qualified person responsible for the technical content is Mark Abrams, AIPG, a Director of the company.
