BP SILVER COMMENCES DRILLING AT COSUÑO SILVER PROJECT

AND ANNOUNCES ONE-YEAR EXTENSION ON PROPERTY PAYMENT

Vancouver, British Columbia – (November 14, 2025) – BP Silver Corp. (TSXV: BPAG) (“BP Silver”

or the “ Company”) is pleased to announce that drilling has commenced at the Cosuño Silver Project

(“Cosuño”), located in the Department of Potosí, Bolivia. In connection with the start of drilling, the

Company has also entered into a Memorandum of Understanding (“MOU”) dated November 5, 2025, with

the vendor of the Cosuño Project (the “Vendor”) to extend the timeline for certain final payment obligations

under the existing share purchase agreement.

“We are thrilled to commence the long -awaited Phase 1 drilling program at Cosuño,” stated Tim

Shearcroft, CEO of BP Silver Corp. “This milestone has been several years in the making as we worked

diligently to build the Company to this stage. I am currently on -site and will remain here throughout the

duration of this very important drill program. We look forward to advancing Cosuño and unlocking the

project’s significant potential.”

Cosuño Drill Program

The structurally controlled outcropping silver -rich polymetallic targets are defined by the presence of

intermediate to advanced argillic alteration and anomalous to highly anomalous geochemical signatures

such as are noted at other large Bolivian silver systems. Four targets within the ~10.5 km 2 hydrothermal

system will be tested by the initial diamond drill program. Please refer to the Company’s October 21, 2025

news release, and Figures 1 & 2 below for more information.
