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, (BHS: TSX -V, BHSIF: OTCQB, 7KXN: FRANKFURT) (the “Company”

or “Bayhorse”) reports that assay results have been received for the last 112 m (370 ft) of the highly

silicified breccia zone encountered from 90 m (300 ft) to the bottom of drill hole BH24-01 at 318 m

(1050 ft) to test a VTEM anomaly at the Bayhorse Silver Mine.

Anomalous values of continuous copper ( up to 510 ppm), zinc (up to 996 ppm) and 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 (1050 ft ) for a total breccia intersection on 228 m (752 ft) . The presence

of chalcopyrite was noted at the bottom of the hole.

Bayhorse CEO Graeme O’Neill comments that, “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 3 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.” O’Neill comments 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 US based mineral operations like the

Bayhorse Silver Mine, that, along with high grade silver, also contains the 3 critical minerals, copper,

antimony and zinc”

Final IP data received shows three low-resistance targets starting 90 meters (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 7

– 9 m (23 – 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 – 50 m (82 -165 ft) below the historic

Sunshine mined stope and is estimated to be similar in size to the historic Sunshine and Junction stopes

(Figure 1), extending the known mineralized strike length to over 600 meters (1980 ft)

Significant volumes of sulfosalts 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 lo w silver prices (<$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 – 170 m (427 – 557ft) ( National

Instrument 43-101 inferred resource of 6.3 m ounces of silver at a grade of 21.65 opt ((673 g/t) (Turner

et al. 2018).

While the Bayhorse mineralization is mainly composed of sulfosalts, Bayhorse senior consulting

geologist, Dr. G.E. Ray, advises there are many cases worldwide where there are sulfide rich deposits

at depth that pass up to sulfosalt rich epithermal mineralization at shallower depths. The 228m (752 ft)

breccia zone encountered may indicate the presence of massive sulfides/copper porphyry at depth.

The IP results by S.J. V Geophysics has, in addition to the low -resistance zones, also identified a

significant chargeability zone (Figure 2) with a N-S strike of +/- 300 m (990 ft) with a vertical extent

of between 75 – 100 m ( 248 – 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 t hat lies 1500m (5000 ft) east of the Bayhorse Mine workings in the State of Idaho, under the

Snake River, to under the Bayhorse Mine.

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, Nevada facility using the PREP -PKG:

Preparation Prep Package. A blank was inserted at the start of the sample submittal and a prepared

standard was inserted every twenty samples. One duplicate was also inserted into the sample stream.

The samples were stored in a locked container on the property 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 30g fire assay,

AQR/digest/AAS or OES finish , and a 35-element suite was analyzed with Paragon’s 35 AR -OES,

which is a thirty five element suite with 1ppm Hg; 0.5gAQR 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 and the Company

no longer has any interest or obligation in the Brandywine project located near Squamish, British

Columbia, and the Company will focus solely on its Bayhorse Silver Mine and adjacent Pegasus

Project..
