Vancouver, British Columbia--(Newsfile Corp. - August 18, 2026) - BP Silver Corp. (TSXV: BPAG) (OTCQB: BPSCF) ("BP Silver" or the "Company") announces an update on its property-wide drone-based magnetic ("MAG") survey at its 100% owned Cosuño Silver Project ("Cosuño") in Bolivia.

As of the date of this news release, the MAG survey is approximately 35% complete and remains ongoing. The survey is designed to cover a minimum of 540-line kilometers at 100-meter ("m") line spacing, with 50 m 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 datasets to further refine the Company’s exploration model and target generation for the Company’s planned 6,000 m Phase 3 diamond drill program, anticipated to commence later this year (Figure 1) (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.
