BP Silver Outlines 2026 Work Program at Cosuño

Vancouver, British Columbia--(Newsfile Corp. - May 14, 2026) - BP Silver Corp. (TSXV: BPAG) (OTCQB: BPSCF) ("BP Silver" or the "Company") outlines its 2026 exploration work program at its Cosuño Silver Project ("Cosuño") in Bolivia. Geochemical sampling, geological mapping, and road construction activities commenced in March 2026 and are continuing across multiple target areas within the large property package. These, and other programs outlined below, are necessary to launch a Phase 2 drill program later this year.

"Following the successful completion of our upsized $10 million financing and highly successful Phase 1 drill program, we are advancing Cosuño through an aggressive 2026 exploration campaign. We believe Cosuño has the potential to become a Tier 1 silver project." stated Tim Shearcroft, Founder and CEO. "MAG survey equipment is currently being mobilized, and logistics are being finalized ahead of the survey commencement. In addition, a drilling contractor has already been secured and will be ready to commence the Phase 2 drill program following completion of the MAG survey and review of all other data collected. With multiple high-priority targets advancing simultaneously, we look forward to providing shareholders with exploration updates in the near future."

Cosuño 2026 Work Program

The 2026 work program consists of the following key components:

1. Construction of access roads to all principal Cosuño targets (see Figure 2).
2. Systematic channel sampling of the principal vein and breccia structures exposed across the property.
3. Completion of a property-wide airborne magnetic ("MAG") survey (See Figure 1).
4. A Phase 2 drilling program designed to follow up on the success of the Phase 1 campaign (see news releases dated February 2 and February 27, 2026). The Phase 2 program is budgeted for approximately 2,000 metres of drilling and will focus on:
   • Testing extensions of high-grade silver intercepts encountered in DH CO-0008 and CO-0009 at Pocañita Chica (see February 27, 2026, news release for full details).
   1. CO-0008 return 38 m @ 116.39 g/t Ag.
          Including 5 m @ 660.40 g/t Ag.
          Including 1 m @ 1,655.00 g/t Ag

2. CO-0009 return 58m @ 46.23 g/t Ag.
       Including 6 m @ 147.10 g/t Ag.
       Including 1 m @ 526.00 g/t Ag.

• Initial testing of newly discovered targets by drilling shallow holes ranging from 50 to 100 metres in length. The 1,000-metre-long vein recently discovered at Jalsuri North East is anticipated to be one of these targets.

5. An induced polarization ("IP") geophysical survey over the principal Cosuño targets.
6. Completion of a Phase 3 drilling program. The Phase 3 program will benefit from the integration of geological mapping, channel sampling, MAG and IP geophysical surveys, and prior drilling results. Together, these datasets are expected to improve significantly the Company's understanding of the geometry, continuity, scale, and tenor of the vein and breccia systems across Cosuño.
