Bayhorse Silver Mobilizes For IP Geophysical Surveys of the Pegasus Porphyry Copper/Silver
Prospect And The Bayhorse Silver Mine
Bayhorse Silver Inc, (BHS: TSX -V, BHSIF: OTCQB, 7KXN: FRANKFURT) (the “Company”
or “Bayhorse”) has begun mobilization to its Pegasus Porphyry Copper/Silver prospect and its silver-
copper-antimony rich Bayhorse Silver Mine in Oregon, USA for an IP survey to be conducted by SJ
Geophysics, commencing October 11, 2025.
The Pegasus IP geophysical survey will cover the large low -resistivity anomal ies identified in the
Company’s airborne VTEM survey conducted in January 2024 to better identify drill targets and depths
into the anomalies. The anomalous area extends over 1.6 km in length and the VTEM results indicate
a vertical extent of at least 550 m (1804 feet) . The survey should discriminate between rocks that
conduct electrical current and those that don’t and can also measure the chargeability of a rock which
is its ability to hold a charge. Rocks with common but disconnected zones of sulfides have the largest
chargeability responses and massive sulphides and copper porphyry are ideal chargeability targets.
The Bayhorse IP survey will extend the area of the orig inal survey to cover the west side of the
Bayhorse Mine. The first survey under the eastern area identified a number of IP anomalies under the
Bayhorse Mine access road. where downhole silver assay results from drill hole WM2 were intersected,
at an interval depth of from 22 to 33.5 m (72 ft to 110 ft) from surface. The most significant s ilver
assay r eported (BHS2025-12) was for two samples from the first 1.5 m (5f ft) of the intersection –
1,486.74 g/t (47.8 opt) and 719 g/t (23.12 opt) for an average 1104 g/t (35.46 opt) within a 10.6 meters
(35 ft) zone of silver mineralization. A second 1.5m (5 ft) silver intersection within the mineralized
zone assayed 770 g/t (23.12 opt), with the 3 m (10 ft) intersection averaging 937 g/t (30.12 oz/t) silver.
(full assay results are shown in table, below)
The Bayhorse exploration model holds that the silver -copper-antimony rich mineralization at the
Bayhorse Silver Mine extends across to the adjacent Pegasus porphyry copper prospect and could have
its source in an underlying shallow pluton(s) that may host porphyry copper mineralization similar to
what Hercules Metals has reported 40 km north of the Bayhorse Silver Mine.

Significant copper credits are associated with silver at the Bayhorse Silver Mine. In 2020, the Company
conducted a metallurgical test on a 200 kg mined sample and passed it through the Company’s Ore -
Sorter that gave a 5 kg Ore-Sorter select sample with a head grade of 985 g/t (28.8 oz/t) silver, 1.16%
copper and 1.87% zinc, The testing achieved silver/copper concentrate recoveries of 86.7%, resulting
in a silver grade of 9,700 g/t and 10% copper. The dominant mineralization at the Bayhorse mine is
Tetrahedrite (BHS2020-12) that has a significant antimony content.
Bayhorse CEO, Graeme O’Neill, Director Christos Doulis and Geologist and Director Mark Abrams
will be at the Bayhorse Mine and Pegasus Project during the IP survey, and CEO Graeme O’Neill and
Director Mark Abrams will be attending the Idaho Mining Conference, Boise, Idaho, October 27 and
28, 2025.
Cautionary statement
The Company is not basing any decision to produce on a feasibility study of mineral reserves
demonstrating economic and technical viability and advises there is an increased uncertainty and
specific economic and technical risk of failure with any productio n decision. These risks include, but
are not limited to, (i) a drop in price of commodities produced, namely silver, copper, lead and zinc,
from the pricing used to make a production decision; (ii) failure of grades of the produced material to
fall within the parameters used to make the production decision; (iii) an increase in mining costs due
to changes within the mine during development and mining procedures; and (iv) metallurgical recovery
changes that cannot be anticipated at the time of production.
All statements herein, other than statements of historical fact, including, without limitation, plans for
and intentions with respect to the Company’s capitalization, preparation of technical reports, proposed
work programs, budgets and proposed expenditur es, permitting, construction and production timing
are forward looking statements. While the Company believes such statements are reasonable, no
assurance can be given that any expectations will prove to be correct and the forward- looking
statements are no t guarantees of future results or performance and that actual results may differ

Bayhorse Silver Mine located in Oregon, USA with a National Instrument 43-101 inferred resource of
292,300 tons at a grade of 21.65 opt (673 g/t) for 6.3 million ounces of silver. (Turner et al. 2018) and
the Pegasus Project, a highly prospective porphyry copper prospect, in Washington County, Idaho. The
Bayhorse Silver Mine and the Pegasus Project are 44 km southwest of Hercules Metals’ porphyry
copper discovery. The Bayhorse Mine is a minimum environmental impact facility capable of
processing at a mining rate up 200 tons/day that includes a state of the art 40 ton per hour Steinert Ore-
Sorter that reduces waste rock entering the processing stream by up to 85 %. The Company has
established an up to 60 ton/day mill and standard flotation processing facility in nearby Payette County,
Idaho, USA with an offtake agreement in place with Ocean Partners UK Limited. The Company has
an experienced management and technical team with extensive mining expertise in both exploration
and building mines.
