BP Silver Corp. Intersects 142 Meters Grading 2.14% Zinc Equivalent, Including 59 Meters at 3.72% Zinc Equivalent and 2 Meters at 495 g/t Silver Equivalent

BP Silver reports broad, high-grade zinc-silver intercepts at Cosuño's Jalsuri North, confirming a new polymetallic system.

What the company is saying

BP Silver Corp. (TSXV:BPAG, OTCQB:BPSCF) is highlighting a major new polymetallic discovery at the Jalsuri North Target within its Cosuño Silver Project in Bolivia, emphasizing broad intervals of zinc and silver mineralization from Phase 2 drilling. The company frames this as evidence of a large, open, intermediate sulfidation hydrothermal system, with mineralization remaining open in all directions. The announcement is data-heavy, focusing on specific grades and intervals, and uses confident language about the project's uniqueness and potential, especially in the context of the Bolivian Silver-Polymetallic Belt. Dr. Stewart D. Redwood (Director, Qualified Person) and Tim Shearcroft (Founder, CEO) are both quoted, reinforcing technical oversight and executive confidence. The company stresses the presence of multiple valuable by-product metals and the potential for higher net smelter returns, but also cautions that further drilling is required to confirm scale and continuity. The tone is bullish, but technical caveats are included regarding the early exploration stage and unconfirmed geometry.

What the data suggests

Drill hole CO-0015 at Jalsuri North intersected 142 meters grading 1.42% zinc and 8.9 g/t silver (2.14% zinc equivalent) from 5 to 147 meters, including a 59-meter interval at 2.57% zinc and 12.25 g/t silver (3.72% zinc equivalent), and a higher-grade 22-meter interval at 5.18% zinc and 27.7 g/t silver (7.75% zinc equivalent). Silver-dominated sub-intervals included 2 meters at 249 g/t silver and 3.46% zinc (495.4 g/t silver equivalent), and 2 meters at 132.0 g/t silver and 0.66% zinc (189.0 g/t silver equivalent). Peak grades in CO-0015 reached 15.2% zinc over 1 meter, copper above 1.0% (with over-limit assays pending), silver up to 288 g/t, and gold up to 1.42 g/t. Bismuth, antimony, and lead values reached 288 ppm, 1,265 ppm, and 8,960 ppm, respectively. Drill holes CO-0011 and CO-0014 at Pocañita Chica returned only anomalous, sub-economic silver values. Metal equivalent grades were calculated using 2025 average prices: US$38.00/oz silver, US$1.30/lb zinc, US$3,300/oz gold, US$4.80/lb copper, US$20.00/lb bismuth, US$1.06/lb lead, and US$25.00/lb antimony, with 90% recovery assumed for all metals. All intervals are core lengths, not true widths. The technical data is detailed and QA/QC procedures are documented, but no resource estimate, tonnage, or economic study is provided. The results confirm a broad, multi-metal mineralized system but leave scale, continuity, and economic viability untested.

Analysis

The announcement is a detailed exploration-stage update, providing specific assay results, intervals, and grades from recent drilling at the Cosuño Silver Project in Bolivia. The language is generally proportionate to the evidence, with most claims supported by disclosed technical data and QA/QC procedures. While the term 'significant new polymetallic discovery' is qualitative, it is substantiated by the grades and intervals reported for CO-0015. Forward-looking statements about potential economic benefits, system size, and future drilling are clearly identified as interpretations or aspirations, not as realised outcomes. There is no evidence of exaggerated claims about imminent production, resource size, or economic value, and no large capital outlay or near-term financial impact is discussed. The project remains at an early exploration stage, so benefits are inherently long-term and contingent on further work.

Risk flags

• ●Resource and economic uncertainty: The project is at an early exploration stage with no resource estimate, tonnage, or economic assessment disclosed, so the economic significance and scalability of the mineralization remain unproven.
• ●Geological continuity risk: The mineralized zones are described as open and unconfirmed in extent and continuity, with the company explicitly stating that further drilling is needed to validate geometry and scale.
• ●Metallurgical and recovery risk: Metal equivalent grades assume 90% recovery for all metals, but no metallurgical test work has been conducted, so actual recoveries and processing characteristics are unknown.
• ●Commodity price and equivalency risk: Equivalent grades are calculated using 2025 average metal prices, which may not reflect future market conditions or actual realized prices if the project advances.
• ●Operational and jurisdictional risk: The project is located in Bolivia, which may present permitting, regulatory, or political risks; the announcement does not address these factors.

Bottom line

BP Silver's new drill results at Cosuño's Jalsuri North Target reveal broad, high-grade zinc and silver intercepts, with significant by-product values in copper, gold, bismuth, antimony, and lead. The technical data is robust for an exploration-stage update, with detailed intervals and QA/QC protocols, but there is no resource estimate, tonnage, or economic analysis yet. The company's narrative is confident and supported by credible technical oversight, but all value remains contingent on future drilling and geological work to confirm scale, continuity, and economic viability. Investors should treat these results as promising but very early-stage, with substantial geological and economic risks remaining. The most important takeaway is that Cosuño now demonstrates a large, multi-metal system with high-grade intervals, but its ultimate value will depend on future resource definition and metallurgical results.

Announcement summary

(TSXV:BPAG, OTCQB:BPSCF) BP Silver Corp. announced new assay results from its Phase 2 diamond drilling program at the Cosuño Silver Project in Bolivia, highlighting a significant new polymetallic discovery at the Jalsuri North Target. The mineralization is located approximately 3 kilometers from the high-grade silver Pocañita Chica occurrence and is interpreted as the upper and/or distal portions of a large intermediate sulfidation hydrothermal system, remaining open for expansion in all directions. Drill hole CO-0015 at Jalsuri North intersected a 142 meter interval grading 1.42% zinc and 8.9 g/t silver (2.14% zinc equivalent) from 5 to 147 meters, including 59 meters grading 2.57% zinc and 12.25 g/t silver (3.72% zinc equivalent) from 5 to 64 meters, and 22 meters grading 5.18% zinc and 27.7 g/t silver (7.75% zinc equivalent) from 19 to 41 meters. CO-0015 also returned a 2 meter silver-dominated intersection grading 249 g/t silver and 3.46% zinc (495.4 g/t silver equivalent) from 35 to 37 meters, and 2 meters grading 132.0 g/t silver and 0.66% zinc (189.0 g/t silver equivalent) from 107 to 109 meters. Additional assay results from CO-0015 included zinc grades up to 15.2% over 1 meter, copper grades exceeding 1.0% (over-limit re-assay results pending), silver grades up to 288 g/t, and gold grades up to 1.42 g/t. The hole also returned bismuth values up to 288 ppm, antimony up to 1,265 ppm, and lead up to 8,960 ppm. The mineralization is hosted by andesite lavas and underlying conglomerates of the San Vicente Formation, controlled by a northwest-trending structure, and occurs as breccia-hosted mineralization, veinlets, fillings, disseminations, and replacements. The mineral assemblage consists primarily of sphalerite and pyrite, with minor chalcopyrite and galena, associated with quartz, calcite, barite, and white clay minerals. Drill holes CO-0011 and CO-0014 at the Pocañita Chica Target intersected anomalous but sub-economic silver mineralization, suggesting narrow feeder-related structures or mineralized splays. Table 1 and Table 2 provide detailed assay results, including intervals, grades, and metal equivalents. Silver equivalent and zinc equivalent grades were calculated using 2025 average metal prices: US$38.00/oz silver, US$1.30/lb zinc, US$3,300/oz gold, US$4.80/lb copper, US$20.00/lb bismuth, US$1.06/lb lead, and US$25.00/lb antimony, with assumed recoveries of 90% for all metals for illustrative purposes. Reported intervals represent core lengths; true widths have not yet been determined. The technical information was reviewed and approved by Dr. Stewart D. Redwood, PhD, FIMMM, Director and Qualified Person. The QA/QC program was supervised by Gonzalo Lemuz, P.Geo, Chief Operating Officer. Samples were prepared by ALS in Oruro, Bolivia, and analyzed in El Callao, Peru, with ALS accredited to ISO/IEC 17025:2017 and ISO9001:2015. BPAG inserted certified standard reference materials, blanks, and duplicates to monitor QAQC. All diamond drill holes were drilled in HQ-diameter core. The average core recovery was 95% for CO-0012 and 97% for CO-0013.
