BP SILVER ANNOUNCES U.S. LISTING ON THE OTCQB UNDER THE SYMBOL "BPSCF" AND COMMENCEMENT OF FIELD WORK AT COSUÑO

BP Silver Corp.'s common shares have commenced trading on the OTCQB marketplace under the symbol BPSCF, effective March 20, 2026. The company's common shares will continue to trade on the TSX Venture Exchange under the symbol BPAG.

Tim Shearcroft, founder, chief executive officer and director of BP Silver, stated: "We are excited to announce our OTCQB listing in the United States -- an important step that increases trading visibility and opens the door to a broader base of U.S. investors. By extending our reach beyond Canada, we're creating new opportunities for investors to participate in our story. The company has built a foundation for scalable growth with the recent exploration success at our flagship Cosuno silver project. We believe this listing will bring added attention to Cosuno -- a Tier 1 opportunity in Bolivia."

The company expects that the listing on the OTCQB will provide greater visibility and convenience of trading for United States investors, resulting in enhanced liquidity and greater reach.

Cosuno silver project fieldwork 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 Cosuno silver project. 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. Pocanita 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 Pocanita Grande and Pocanita Chica.

To date, the strongest drill results at Cosuno have been returned from veins hosted in dacite at Pocanita Chica, including 38 metres grading 109.1 grams per tonne 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 one to five m (see Feb. 27, 2026, news release).

The field program will map rock types, alteration and structures, with a focus on multiple vein sets outcropping at Pocanita 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, Cosuno appears to host a mineralized lithocap over vein structures.

Tim Shearcroft, founder, CEO and director of BP Silver, stated: "Pocanita Grande is looking to be the center of the approximately 10.5 square km mineralized system at Cosuno. 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."
