BP Silver Discovers Multiple New Veins and Breccia Structures at the Cosuño Silver Project
Rhea-AI Summary
BP Silver (OTCQB:BPSCF) reported new geological mapping at the Cosuño Silver Project in Bolivia, extending the mineralized corridor to approximately 3.5 km. Work at the Jalsuri, Jalsuri Northeast, and Jalsuri North targets has identified 16 outcropping veins and breccia structures totaling about 2,100 m of strike length.
Over 200 new chip and channel samples have been collected in the current campaign, with more than 520 samples gathered since project inception. According to BP Silver, mapping indicates both higher-grade vein potential and possible bulk-tonnage targets, with assays from the latest samples expected by early June 2026.

New Veins and Breccia Structures Extend the Mineralized Corridor Width to 3.5 km
Vancouver, British Columbia--(Newsfile Corp. - May 19, 2026) - BP Silver Corp. (TSXV: BPAG) (OTCQB: BPSCF) ("BP Silver" or the "Company") announces that recent geological mapping has discovered multiple new veins and breccia structures, extending the mineralized corridor to approximately 3.5 kilometers ("km") at the Cosuño Silver Project ("Cosuño") (Figure 1) in Bolivia. To date, the Company has collected more than 200 new chip and channel samples, with assay results currently pending.
Geological mapping within the Jalsuri target and the new target areas of Jalsuri Northeast and Jalsuri North has identified 16 outcropping veins and breccia structures, including one structure with an inferred strike length of approximately 1,000 meters ("m") and widths of up to 40 m (Figure 2). The aggregate length of veins and breccia structures at these Jalsuri targets areas sums to approximately 2,100 m.
Stewart D. Redwood, Director and QP, commented: "The Cosuño silver system has been extended to the northeast by geological mapping and channel sampling which has identified multiple new veins and breccias of different orientations and up to 1,000 m in length. These show the robustness and scale of the Cosuño silver system and potentially constitute important new drill targets."

Key Highlights: Jalsuri, Jalsuri Northeast, and Jalsuri North Targets
Recent exploration at three of the four Jalsuri targets — Jalsuri, Jalsuri Northeast, and Jalsuri North (see Figures 1 and 2) — has significantly advanced the Company's understanding of the structures controlling silver mineralization in the area. A key result is the identification of 16 prominent vein and breccia structures that sum to over 2,100 m of strike length. In addition to the prominent veins and breccias, geological mapping has recorded numerous minor structures and micro-veining with variable orientations within the vein field. The observation of widespread stockwork mineralization outside of the discrete veins puts forth the potential for a bulk-tonnage target in addition to the higher-grade vein targets. To date, 200 new chip and channel samples have been collected across the area (Figure 2).
Jalsuri
- Four short drill holes from Cosuño's Phase 1 drill program at the Jalsuri target returned a best result of 29.0 m grading 56.03 g/t Ag and 0.28 g/t Au (75.15 g/t AgEq) in breccia (see news release dated February 2, 2026).
- Geologists have identified outcropping breccia to the northwest of Jalsuri (Breccia #7, Figure 2), displaying mineralogical and textural characteristics similar to those observed at the Jalsuri structure. Geologists believe this outcropping breccia extends the Jalsuri breccia by an additional 100 m.
Jalsuri Northeast (New Target)
- Two principal east-west trending structures, dipping north, have been mapped.
- The northern east-west structure extends for approximately 1,000 m, representing the most significant mineralized structure identified to date in the Jalsuri area.
- The southern east-west structure occurs as an outcropping breccia (Breccia #4, Figure 2) located ~100 m south of the northern structure. It is interpreted as a split from the northern structure. This breccia is ~60 m in strike length and 10 m in width.
Jalsuri North (New Target) - Secondary Structural Corridor
A northwest-southeast trending vein structure has been delineated, with a strike length exceeding 300 m (Vein #3, Figure 2). This vein is interpreted to be a continuation of the Jalsuri structure, as outlined above.
- In addition to the 300 m structure, there are two subordinate north-south trending structures (Vein #9 and Vein #8, Figure 2) which disappear to the south under cover indicating a potential for concealed targets.
- Detailed mapping has recorded the widespread presence of numerous veinlets and disseminated sulfide and sulfosalt minerals between the principal mapped veins, suggesting the potential for a bulk-tonnage target.
Mapping and channel sampling will continue at all four Jalsuri targets as well as at the other targets occurring throughout the Cosuño project area (Figure 1). Ongoing fieldwork is focused on further defining the scale, continuity, and structural controls of mineralization in advance of future drill testing.
To date, BP Silver has collected over 520 chip and channel samples across the property since the project's inception, including more than 200 samples collected during the current exploration campaign. Additional sampling remains ongoing. The first batch of assay results is anticipated to be received by the first week of June, with results expected to be announced shortly thereafter.
