Bayhorse Silver Extends Known Silver Mineralization At The Bayhorse Silver Mine,
Oregon, USA to Over 400m E-W and 563m S-N.
Bayhorse Silver Inc, (BHS: TSX-V, BHSIF: OTCQB, 7KXN: FRANKFURT) ( “ Bayhorse”
or the “Company” ) reports it has increased the known extent of mineraliz ation at the
Bayhorse Silver Mine, to over 400 m E -W (1,312 feet) and 560 m (1850 ft) N -S with a now
known vertical extent of 91 m (300 ft)).
Two new mineralized zones have been confirmed at 310 ft and 380 ft under RC hole MW-1,a
725 foot vertical hole that was collared at 862 m (2,830 ft) ASL elevation, and 365 m (1200
ft) S-W of the Bayhorse Mine portal. The new zone lies 198 m (650 ft) S -W of the historic
“Goldilocks” historic mined area at a similar elevation, where mined rounds grading up to 100
oz/t silver were partially mined in 1984 (Silver King Mines, 1984)
A second new mineralized zone has also been identified 30m (100 feet) under RC hole MW-
3, a 220 foot vertical hole that was collared 36.6 m (120 ft) S-E of the Bayhorse Mine portal
at 713 m (2340 ft) ASL elevation, and which is 126 m (415 ft) south from, and at the same
elevation as the recently announced 3 m (10 ft) intersection of 917 g/t (29.6 opt) reported in
the Company’s news release BHS2025-12 . and BHS-2015-16, The width and thickness of
the new zones is unknown at this time.
Bayhorse CEO Graeme O’Neill comments that, “By significantly extending the known areas
of high-grade silver mineralization, further dill testing and sampling may lead to an increase
in the Company’s 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). With the Bayhorse
and Pegasus claims renewed until August 2026, we are looking to extend the Bayhorse silver
mineralization onto our adjacent “760 m (2,500 ft ) apart, nearly 9 sq/km (4 sq/mile) Pegasus
project with our upcoming IP survey, that may also identify the presence of potential porphyry
copper mineralization.”

Drill cuttings were split and placed in sealed bags for preparation and subsequent analysis.
The balance of the cuttings are retained in secure storage at the Mine. Silver fire assays will
be conducted by Christopherson Inc. Umpire Assayers, Smelterville, Idaho. using 30g fire
assay with a gravimetric finish for silver. The sample pulps created at Christopherson Inc.
will then be submitted to Paragon Geochemical’s Sparks, Nevada facility for a 35 element
suite using Paragon’s 35 AR-OES (Aqua Regia digestion) & ICP (Induced Coupled Plasma)
multi-element method. Samples showing anomalous silver in the 35 element scan will also
be assayed for silver using Ag 30g fire assay, AQR/digest/AAS or OES finish.
A blank was inserted at the start of the sample submittal and a prepared standard inserted
every twenty samples. One duplicate was also inserted into the sample stream. The samples
were stored in a secure facility on the property then transported to the laboratory in a secure
container in a pickup truck by the project geologist.

About Bayhorse Silver Inc.
Bayhorse Silver Inc. is an exploration and production company with a 100% interest in the
historic 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, 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. The Company has an experienced
management and technical team with extensive mining expertise in both exploration and
building mines.
