Core Silver (OTCQB:CCOOF) reported drill hole LAV25-011 at the Laverdiere Copper Project intersected broad Cu-Mo-Ag porphyry mineralization from surface to >725m and extended interpreted porphyry mineralization by 300 metres.
The 2025 campaign completed 7 holes for a combined 3,857 metres. Company mapping and drilling now trace porphyry-style Cu-Mo-Ag±Au mineralization over 4.5 kilometres, and LAV25-011 reached a final depth of 800 metres with coarse Cu-Mo veins up to 40 cm below 550m. Assays for 2025 holes are pending and the system is reported open laterally and at depth.
Core Silver (OTCQB:CCOOF) released first visuals from drill hole LAV25-010 at the Laverdiere Copper Project on November 28, 2025. The hole was drilled to 703.77 m and shows porphyry-style Cu-Mo-Ag mineralization from surface to over 675 m, with vertical zonation from Ag-Mo near surface to Mo+Cu at depth. The 2025 program completed seven holes totaling 3,857 m and traced porphyry-style mineralization over 4.5 km along the Valley Fault Zone. Surface assays earlier in 2025 reached 366 g/t Ag, 0.71% Cu, and 0.54% Mo. All assay results for 2025 holes are pending.

Core Silver (OTCQB:CCOOF) reported widespread gold and silver results from the 100%-owned Silver Lime Polymetallic Project in the Atlin Mining District, British Columbia on November 3, 2025. Exploration shows a Porphyry–Skarn–CRD–Epithermal continuum with precious-metal enrichment across a 9.5×10 km footprint. Key surface and drill highlights include high-grade rock samples and multiple gold-bearing vein occurrences at North Gold, Falcon, Jackie, Pete's, Amp, Pike Valley and Grizzly.
Notable assays include a 19.50 g/t Au surface sample at Falcon, a 1,145 g/t Ag with 23% Pb and 23.5% Zn intercept at Grizzly, and drill intercepts such as 2 m @ 5.42 g/t Au from 335 m at Jackie. 2025 Jackie drilling exceeded 200 m; assays are pending.
Core Silver (CCOOF) announced discovery of a new copper-bearing porphyry vein system at Copper Creek, part of the Laverdiere project in the Blue Property, Atlin Mining District, BC (October 20, 2025).
Key highlights include surface assays up to 1.35% Cu with 9.1 g/t Ag, and 0.63% Cu with 17 g/t Ag and 355 ppm Mo. The company says Cu-Mo-Ag mineralization is now confirmed across a 4.5-kilometre footprint and remains open for expansion; the new copper porphyry lies ~2.6 km south of the Valley Fault Zone. Additional 2025 exploration results, including drilling, will be released when available.
Core Silver (CCOOF) reported 2025 exploration results at the Laverdiere Copper Project, Atlin, BC, following prospecting, mapping, 65 rock and 197 soil samples and 2,769 metres of diamond drilling across six holes.
Highlights include surface assays up to 366 g/t Ag, 0.71% Cu and 0.54% Mo, earlier surface results of 316 g/t Ag, 0.62% Cu, 0.78% Mo, newly mapped porphyry veins at Copper Creek 2.3 km south, and confirmed Cu-Mo-Ag mineralization across 4.4 km strike. Several drill holes remain with assays pending and drilling continues into fall 2025.
Core Silver Corp. (OTC.QB:CCOOF) has announced significant drilling results from its Jackie Target at the Silver Lime Polymetallic Project in British Columbia. The company completed three diamond drill holes totaling 564 meters, successfully extending high-grade silver-polymetallic sulphide mineralization.
Key findings include drill hole SLM25-067, which intersected argentiferous galena and sphalerite-bearing sulphide mineralization over 150m, confirming mineralization continuity to 182m true depth. Surface samples revealed exceptional grades, including 1,090g/t Ag with >20% Pb, 5.73% Zn and 2.0% Cu.
The company also announced the resignation of director Andrew Carne and engaged Upswitch Media Corp. for marketing services in a $1,000,000 contract over four months.
