BP Silver Commences Drilling at Cosuño Silver Project and Announces One-Year Extension on Property Payment

Vancouver, 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 km² 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.
