BAYHORSE SILVER REPORTS ANOMALOUS COPPER-ZINC ASSAY RESULTS FROM THE LAST 112 M OF DRILL HOLE BH24-01 FROM 207 M (680FT) DOWNHOLE TO END OF HOLE AT 318 M (1050 FT)

Bayhorse Silver Inc. has received assay results for the last 112 metres (370 feet) of the highly silicified breccia zone encountered from 90 m (300 ft) to the bottom of drill hole BH24-01 at 318 m (1,050 ft) to test a VTEM anomaly at the Bayhorse silver mine.

Anomalous values of continuous copper (up to 510 parts per million), zinc (up to 996 ppm), intermittent anomalous gold values (up to 0.02 ppm) and intermittent silver values (up to 3.2 ppm) were encountered in the final 112 m (370 ft) of the brecciation zone that extends from 90 m (300 ft) to the bottom of the hole at 318 m (1,050 ft) for a total breccia intersection on 228 m (752 ft). The presence of chalcopyrite was noted at the bottom of the hole.

Bayhorse chief executive officer Graeme O'Neill commented: "We were pleasantly surprised to encounter 228 m (752 feet) of mineralized breccia in our first drill hole as it confirms the epithermal nature of the Bayhorse mine deposit.

"With the IP survey identifying three low-resistivity drill targets on strike with and close to existing mined stopes, it potentially expands the known mineralized zone and provides three new high-priority drill targets."

Mr. O'Neill commented further: "The company's sole focus in 2025 will be on its Bayhorse and Pegasus projects, especially as President Donald Trump's executive order to increase American mineral production is a positive step for U.S.-based mineral operations like the Bayhorse silver mine, that, along with high-grade silver, also contains the three critical minerals: copper, antimony and zinc."

Final induced polarization data received show three low-resistance targets starting 90 metres (300 feet) to the immediate east of and below the previously mined historic Sunshine stope. The Sunshine, Junction and Big Dog stopes extending over a strike length of 160 m (528 ft) were up to 10 m (33 feet) wide, and between seven and nine m (23 to 30 feet) in height, and up to 36 m (120) feet in length.

The first IP drill target lies 90 m (300 ft) east of, and between 25 and 50 m (82 to 165 ft) below the historic Sunshine mined stope, and is estimated to be similar in size to the historic Sunshine and Junction stopes, extending the known mineralized strike length to over 600 metres (1,980 ft).

Significant volumes of sulphosalts containing high-grade silver, up to 240 ounces per ton, along with the critical minerals, copper, antimony and zinc, were mined from these three stopes, prior to the Bayhorse silver mine being closed in late 1984 due to low silver prices (less than $5 per ounce) (Silver King Mines, 1984). Silver, copper, antimony and zinc mineralization has been identified in veins and stockworks west of the Big Dog stope over a strike length of between 130 and 170 m (427 to 557 ft) (National Instrument 43-101 inferred resource of 6.3 million ounces of silver at a grade of 21.65 ounces per ton (673 grams per tonne) (Turner et al., 2018).

While the Bayhorse mineralization is mainly composed of sulphosalts, Bayhorse senior consulting geologist Dr. G.E. Ray advises there are many cases worldwide where there are sulphide-rich deposits at depth that pass up to sulphosalt-rich epithermal mineralization at shallower depths. The 228-metre (752 ft) breccia zone encountered may indicate the presence of massive sulphides/copper porphyry at depth.

The IP results by S.J. V Geophysics have, in addition to the low-resistance zones, also identified a significant chargeability zone with a north-south strike of plus or minus 300 m (990 ft) with a vertical extent of between 75 and 100 m (248 to 330 ft) within the VTEM geophysics signature within the rhyolite hosted copper- and silver-rich Bayhorse silver mine deposit. A priority is to extend the IP geophysical survey onto the Pegasus project to better identify drill targets as soon as ground conditions permit.

The Bayhorse exploration model holds that the rhyolite hosted silver-copper-zinc-antimony-rich mineralization at the Bayhorse silver mine could have its source in an underlying shallow pluton that may host porphyry copper mineralization. The rhyolite extends from the Pegasus project and its VTEM anomaly that lie 1,500 m (5,000 ft) east of the Bayhorse mine workings in the state of Idaho, under the Snake River, to under the Bayhorse mine.

Quality assurance/quality control measures, chain of custody

Drill cores were cut in half using a diamond saw and placed in sealed bags for preparation and subsequent analysis by Paragon Geochemical's Sparks, Nev., facility using the preparation prep package. A blank was inserted at the start of the sample submittal, and a prepared standard was inserted every 20 samples. One duplicate was also inserted into the sample stream. The samples were stored in a locked container on the property and then transported to the laboratory in a secure container in a pickup truck by the project geologist.

Each prepared sample was assayed for gold using Paragon's Au-FA30: Au 30-gram fire assay, AQR/digest/AAS or OES finish, and a 35-element suite was analyzed with Paragon's 35 AR-OES, which is a 35-element suite with one part per million mercury; 0.5-gram AQR digestion/ICP-OES finish.

The company advises that, as the Brandywine option agreement expires on April 5, 2025, the company and the Brandywine owners have mutually agreed to terminate the option agreement, the company no longer has any interest or obligation in the Brandywine project located near Squamish, B.C., and the company will focus solely on its Bayhorse silver mine and adjacent Pegasus project.

About Bayhorse Silver Inc.

Bayhorse is an exploration and production company with a 100-per-cent interest in the historic Bayhorse silver mine located in Oregon, United States, and the Pegasus project, in Washington county, Idaho. The Bayhorse silver mine and the Pegasus project lie 44 kilometres southwest of Hercules Metals' porphyry copper discovery. The Bayhorse mine includes a state-of-the-art Steinert ore-sorting technology reducing waste rock entering the processing stream by up to 85 per cent. The company has created a minimum environmental impact facility capable of mining 200 tons of mineralization per day and the ability to process and supply 3,600 tons per year of silver/copper concentrate ranging between 7,500 to 15,000 grams per tonne using standard flotation processing at its milling facility in nearby Payette county, Idaho, United States, with an offtake agreement in place with Ocean Partners U.K. Ltd. The company has an experienced management and technical team with extensive mining expertise in both exploration and building mines.
