BAYHORSE ENGAGES HDR ENGINEERING TO CONDUCT GROUND WATER STUDY

AT THE BAYHORSE MINE

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

or “Bayhorse”) announces that on August 17, 2023, it has engaged HDR Engineering of Boise, Idaho,

to conduct a ground water baseline study at its Bayhorse Silver Mine, Oregon, USA.

Subject to completion of the ground water baseline study, the C ompany expects to submit its final

Operation Permit Application (“A pplication”) to Oregon’s Depart ment of Mining and Geological

Industries (“DOGAMI”) for approval to recommence full mining op erations at the Bayhorse Silver

Mine.

The Company is required to submit a number of baseline studies to DOGAMI in support of its

Application. These baseline studies include vegetation, soil/overburden, climate/air quality/

precipitation (including modeling 100-year, 24-hour precipitation event), fish/aquatic biology,

wildlife (terrestrial/avian), surface water, groundwater, area seismicity, geology and geographic

hazards, mineralogy and chemistry and noise. Only the noise and groundwater baseline studies

remain to be completed. The groundwater testing requires the installation of three test wells on the

Bayhorse property.

Bayhorse CEO, Graeme O’Neill, comments, “while the baseline studies cover a comprehensive

number of subjects, the Company is incorporating into its baseline reports published data from the

substantial baseline studies already completed by Idaho Power Corporation (“IPC”) in support of

their relicensing application of their Hell’s Canyon Hydro-Electric Complexes to the US FEC that

commenced during 2000. The baseline data has since been submitted to, reviewed, and majorly

accepted by the regulatory authorities of both Oregon and Idaho, as well as the US EPA, (2022) in

their licensing approval process. The Bayhorse Mine is located on the Oregon side of IPC’s

Brownlee Dam Reservoir on the Snake River, that forms part of the Oregon/Idaho State boundary.

Graeme also comments that since the supply disruptions during t he Covid period, attention has been

drawn to the many critical minerals that have minimal production in the United States. At the Bayhorse

Flotation Mill in Payette, Idaho. Each ton of flotation concent rate produced at its flotation mill

contains, along with the silver c ontent, an average 10% antimon y, a US critical mineral, and.10%

copper. Very little antimony is mined in the U.S., and the recent 99.6% ingot antimony price has been

reported as high as US$11.70/Kg.

Subject to approval of the TSX Venture Exchange, the Company ha s amended the price of its

previously announced (07.10/2023) non-brokered private placemen t at $0.02 cent per Unit to $0.015

cents per Unit and increased the size of the placement to 8 million units for gross proceeds of $120,000.

Each unit will consist of one common share, and one transferrab le common share purchase warrant,

each warrant exercisable into one common share of the Company at a price of $0.05 cents per common

share for a period of 15 months from issuance.

The funds received are to complete the deficiencies on the Company’s full operating permit application

for the Bayhorse Silver Mine, to complete the reclamation of th e Flagstaff propert y and for general

and administrative expenses.

In addition to any other exemption available to the Company, pa rticipation in the non-brokered

financing is also open to all existing Canadian shareholders, even if not accredited investors, under the

“existing shareholder” exemption of National Instrument 45-106 as promulgated in Multilateral CSA
