BP Silver Initial Drilling Intersects Significant Mineralization Within Cosuño Lithocap
BP Silver Corp. (TSXV: BPAG) (‘BP Silver‘ or the ‘Company‘) announces assay results (‘Assays‘) from the first two drill holes of its eleven-hole Phase I drill program (the ‘Program‘) at the Cosuño Silver Project (‘Cosuño‘) in Bolivia. The Company expects to release assays from the remaining nine drill holes over the coming weeks. The Company also announces that Dr. Mark Cruise, has been appointed as the Company’s Executive Chair.
Dr. Stewart D. Redwood, Director and Qualifying Person stated, ‘Cosuño is a 10.5 square kilometer zone of alteration. The Program tested only four targets in the southern portion of Cosuño, selected as initial targets because they were outcropping. We expect there to be many more hidden targets as most of the area is covered by surficial overburden. We are literally scraping the surface with two short holes into this extensive system, and it is very significant that Cosuño’s lithocap is mineralized as lithocaps are usually barren.’
Dr. Redwood continued, ‘We expect Cosuño’s grades to increase when we drill deeper into and below the lithocap. Lithocaps are extensive zones of clay and silica alteration that form in the top part of Bolivian polymetallic vein systems and tin porphyries, similar to those which overlie porphyry copper deposits. The nearest neighbour to Cosuño, in a similar geological setting, the Pulacayo deposit, has a large lithocap that is barren and conceals a major vein that produced 640 million ounces of silver and 200,000 tons each of lead and zinc.’
Key Highlights from Cosuño’s Initial Results
Assays released are from the first two drill holes, Hole CO-0001 and CO-0002, which tested one of four initial surface targets identified within the large ~10.5km2 Cosuño hydrothermal system (Table 1 & Figure 1). The assays demonstrate that silver and gold mineralization identified at surface continues at depth within the lithocap. The results are significant because mineralized Lithocap’s are usually barren in similar Bolivian systems, indicating Cosuño’s potential for further discoveries at depth and in covered areas.

Notes to the table:
- Silver equivalent (AgEq) = Ag + (Au * Au price/ Ag price). Assumes a recovery of 100% Ag and 100% Au given the project is early stage and there is no metallurgical test work to date.
- Prices used Au $3431.54/oz, Ag $40.03/oz (London Bullion Market Association 2025 Average)
- Above are core lengths as true widths are not known at this time.
Dr. Redwood commented, ‘The gold grades are higher than expected and over significant widths in the Jalsuri target. These results have achieved one of the objectives of the Phase I drill program which was to confirm that the silver anomalies defined by surface rock sampling continue at depth.’
Cosuño Drill Program Overview
The Program tested four high priority targets defined by structurally controlled, outcropping geochemically anomalous to highly anomalous silver-rich polymetallic zones characterized by silicification, intermediate to advanced argillic alteration, sulfides and brecciation: features typical of many significant Bolivian silver deposits. The targets occur within a large ~10.5 km² hydrothermal alteration system as defined by detailed mapping, geochemical sampling and remote sensing alteration studies.
Figures and additional geological background from the initial program can be found in the Company’s October 21, 2025, and November 14, 2025, news releases. Additional results from remaining nine holes will be released once received by assay labs over the coming weeks.
Detail
This marks the first drill program completed within the Cosuño Lithocap: Holes CO-0001 and CO-0002 were drilled in the Jalsuri target, a northwest-southeast trending ridge formed by a prominent mineralised structure (Figure 1 and 2).
CO-0001 (Easting 747065 Northing 7762846) was drilled at an inclination of -45° and direction of 235° to a depth of 101.0 m. CO-0002 (Easting 747063 Northing 7762848) was drilled from the same platform at an inclination of -45° to an azimuth of 175° to a depth of 107.0 m (Table 1, Figure 1 & 2). Both holes cut tuffs with hydrothermal breccias, advanced argillic and argillic alteration, strong silicification, and semi-massive pyrite, all cut by late drusy veinlets of quartz, pyrite, tetrahedrite and silver sulphosalts (Figures 3 to 4).

As Dr. Redwood is a director of the Company, he is not independent under National Instrument 43-101.
Mineralization at the Pulacayo deposit is not necessarily indicative of mineralization at the Cosuño Project. Information on production from the Pulacayo deposit was obtained SERGEOMIN, Bulletin of the National Service of Geology and Mining, No. 30, pp. 119-120.
QA/QC
The work program was designed and supervised by Gonzalo Lemuz, P.Geo, the Company’s Chief Operating Officer, who was responsible for all aspects of the work, including the Quality Assurance and Quality Control (QA/QC) program. On-site personnel at the Project rigorously collect and track samples which are then security sealed and shipped to ALS laboratory in Oruro for sample preparation. The core samples were prepared by ALS at their laboratory in Oruro, Bolivia and the sample pulps were shipped to their laboratory in El Callao, Peru for analysis. ALS is accredited to ISO/IEC 17025:2017 and ISO9001:2015. ALS is independent of BP Silver. Silver and multi-elements were analysed by aqua regia digestion and ICP-MS finish. Gold was analysed by fire assay and AA finish. BPAG inserted certified standard reference materials (CSRM), blanks and duplicates to monitor QAQC. All diamond drill holes were drilled in HQ diameter. The average core recovery was 97.5% for CO-0001 and 95% for CO-0002.
