Bayhorse Silver Extends Bayhorse Breccia Zone From 90 M (300ft) Downhole to 318 M (1050 ft)
Reports Anomalous Copper-Zinc Assay Results F rom The First 115 M Of The Breccia Zone,
And Preliminary IP Results
Bayhorse Silver Inc, (BHS: TSX -V, BHSIF: OTCQB, 7KXN: FRANKFURT) (the “Company”
or “Bayhorse”) reports that assay results have been received for the first 115 m (380 ft) of the silicified
breccia zone encountered 90 m (300 ft) downhole in drill hole BH24- 01 to test a VTEM anomaly at
the Bayhorse Silver Mine.
Anomalous values of continuous copper, (up to 125 ppm) and zinc (up to 695 ppm) and intermittent
anomalous gold values (up to 0.023 ppm) were encountered in the first 115 m (380 ft) of the
brecciation zone that now extends to the current bottom of the hole at 318 m (1050 ft). A further 112
m of samples of brecciation and rhyolite have been submitted for assay. The presence of chalcopyrite
was noted at the bottom of the hole.
As well, the preliminary IP results by S.J. V Geophysics, that are overlaid on the geologic map,
(figure 1) has identified both chargeability (green) and low resistance targets (blue) extending to
depth within the VTEM geophysics signature within the rhyolite hosted copper and silver rich
Bayhorse Silver Mine deposit. The IP geophysical survey will be extended onto the Pegasus project
as soon as ground conditions permit..
Bayhorse CEO Graeme O’Neill comments “ we are very encouraged by the continuous copper /zinc
mineralization in the upper 115 m (380 ft) part of the 227 m (750 ft) length breccia intersection that
lies in close proximity to the IP chargeability and low-resistance zones that may indicate the presence
of massive sulfides/copper porphyry.”
Drilling BH24-01 has confirmed that the Bayhorse Ag-Cu-Zn-Sb mineralization is epithermal in nature
and is expected to extend to significant depths. In Hole BH24-01 there are areas of strong silica
flooding, epithermal-style vuggy quartz veining, sporadic tetrahedrite mineralization and hydrothermal
brecciation. This extends from 90m (300 ft) to the current bottom of the hole at 318 m (1050 ft). This
alteration could mark the hole’s proximity to a porphyry or related epithermal system.

In figure 1, the top of silver bearing rhyolite dyke 1 has been cut and offset by thrusting, and the
overlying segment (dyke 2) has been displaced to the south. This displaced section, with an estimated
vertical extent of 120 m (396 ft) is the area of the Company’s planned mining based on the 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).

The Company’s senior consulting geologists have suggested the zone is a highly silicified
hydrothermal polymictic breccia. It contains multiple rounded, “milled” clasts that probably resulted
from high pressure fluids derived from a buried pluton streaming up through the breccia. (BHS2024-

Bayhorse Silver CEO, Graeme O’Neill, further comments, “the 3D representation of our recently
concluded surface and downhole IP program will better allow us to drill target the identified
chargeability (green) and low resistance (blue) zones within the VTEM signature information low"
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 feet) east of the Bayhorse Mine workings in the State of Idaho, under
the Snake River, to under the Bayhorse Mine.
The final baseline study for the Bayhorse Mine Permitting is planned to be completed by the end of
June 2025, at which time the final Operating Permit Application will be made . Once permitting is
approved, silver/copper/antimony concentrate production can resume.
Bayhorse CEO Graeme O’Neill comments “with the gold price rising to US$2 900 per ounce ,
(goldprice.org) the future price of silver is also expected to increase. The silver/copper concentrate that
the Company has already produced also contains +/ - 12% antimony, which is a critical mineral. The
price of antimony surged 200% in 2024, and antimony ingots are currently priced at US$25,000/ton.

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.
A total of 81 samples were analyzed. There were no overlimit samples. Analysis certificates were
examined, and no irregularities were found.
