Channel Sampling and Geologic Mapping Program Initiated over Pocañita Grande, Panita East and Jalsuri West

Vancouver, March 20, 2026 - BP Silver Corp. (TSXV: BPAG) (OTCQB: BPSCF) ("BP Silver" or the "Company") announces that its common shares have commenced trading on the OTCQB marketplace under the symbol "BPSCF", effective March 20, 2026.

The OTCQB Venture Market is for early stage and developing U.S. and international companies. Investors can find real-time quotes and market information for the Company on www.otcmarkets.com.

Cosuño Silver Project Field Work Update

The Company also announces that heavy machinery has been mobilized to complete road repairs following the rainy season and to establish new access roads at the Cosuño Silver Project ("Cosuño"). Field mapping and sampling of newly identified target areas are expected to commence immediately, while planning for the geophysics program continues.

Several new targets have been identified and will be the focus of upcoming mapping activities. Pocañita Grande remains the Company's highest-priority target and has yet to be drilled. Notably, dacite-a type of volcanic rock commonly associated with mineralization-has been identified at both Pocañita Grande and Pocañita Chica.

To date, the strongest drill results at Cosuño have been returned from veins hosted in dacite at Pocañita Chica, including 38 m grading 109.1 g/t silver equivalent in Hole C0-0008 and 58 m grading 44.6 g/t silver equivalent. Both holes intersected high-grade silver zones exceeding 500 g/t Silver over widths of 1-5 m (see Figure 1 and February 27, 2026 news release).

The field program will map rock types, alteration, and structures, with a focus on multiple vein sets outcropping at Pocañita Grande, Jalsuri East, and Jalsuri West, followed by channel sampling to determine metal content. While Bolivian silver systems typically form barren outcrops within lithocap alteration, Cosuño appears to host a mineralized lithocap over vein structures.

Tim Shearcroft, Founder, CEO, and Director of BP Silver, stated: "Pocañita Grande is looking to be the center of the ~10.5 sq. km mineralized system at Cosuño. We are excited to build access to this area so we can complete the necessary geological work, including detailed mapping and sampling. We are also excited to begin mapping and sampling new areas to expand the already significant mineralized footprint. Together with the upcoming geophysical program, this work is expected to identify high-quality drill targets to be tested later this year."

Qualified Person

The technical information contained in this news release has been reviewed and approved by Dr. Stewart D. Redwood, PhD, FIMMM, a Director of the Company and a Qualified Person as defined under National Instrument 43-101 - Standards of Disclosure for Mineral Projects. As Dr. Redwood is a director of the Company, he is not independent under National Instrument 43-101.

Notes to the Map:

1. Intersections calculated at cutoff grades of 10 g/t Ag with sub-intervals at 30, 60 and 90 g/t Ag, or 0.5 and 1.0 g/t Au. The intervals may include some internal dilution.
2. Au for CO-0001 and CO-0002 is by fire assay 30 g with AAS finish (AA-25).
3. Au for CO-0003 to CO-0009 is by ICP (ME-MS41) which is semi-quantitative and is preliminary until fire assay (AA25) is completed.
4. Ag and multielement were analyzed by aqua regia and ICP-MS (ME-MS41). Ag >100 ppm was reassayed by aqua regia and ICP-AES (Ag-OG46). Ag > 1000 g/t was reassayed by fire assay and gravimetry (AgGRA46).
5. AgEq = (Ag grade * Ag recovery) + ((Au grade * Au price/ Ag price) * Au recovery).
6. Prices Au $3431.54/oz, Ag $40.03/oz (London Bullion Market Association average 2025).
7. The project is at an early stage, and there is no metallurgical test work to date. Assumed recoveries are 93% Ag and 96% Au by comparison with the Santa Ana deposit, Colombia (NI 43-101 mineral resource report for Outcrop Silver & Gold Corp., 8 June 2023).
8. For CO-0001 and CO-0002, AgEq is restated from the prior press release using the assumed recovery factors.
