BP SILVER PROVIDES UPDATE ON DRONE MAGNETIC SURVEY AT THE COSUNO SILVER PROJECT, BOLIVIA

BP Silver Corp. has provided an update on its property-wide drone-based magnetic (Mag) survey at its 100-per-cent-owned Cosuno silver project in Bolivia.

As of the date of this news release, the Mag survey is approximately 35 per cent complete and remains continuing. The survey is designed to cover a minimum of 540 line kilometres at 100-metre line spacing, with 50-metre line spacing to be utilized, where warranted, over areas requiring higher-resolution coverage.

Data collected from the Mag survey will be integrated with existing geological mapping, surface sampling, drilling and other geophysical data sets to further refine the company's exploration model and target generation for the company's planned 6,000-metre phase 3 diamond drill program, anticipated to commence later this year (see news release dated May 14, 2026, for more information on the 2026 work program). The company will provide further updates as the Mag survey progresses and results become available.
