(TSXV: SICO) (\"Silverco\" or the \"Company\") is pleased to report the third batch of assay results from its 15,000 metre 2025 diamond drill program at the Company's 100%-owned Cusi Property (\"Cusi\"), located approximately 90 kilometres northwest of First Majestic's Los Gatos Mine in Chihuahua, Mexico.The latest drilling at the San Miguel zone has successfully identified a series of steeply-dipping, closely spaced parallel veins, returning mineralized widths significantly exceeding historical averages for the district.While previous drilling had encountered a single broad vein among multiple other veins across the San Miguel system, these latest results confirm a significant evolution in the geological model: multiple parallel structures are now simultaneously exhibiting broad widths and high grades. Hole CU-25-37 intersected a cluster of mineralization including 12.4 metres grading 273 g/t AgEq, 8.8 metres grading 319 g/t AgEq, and 8.8 metres grading 172 g/t AgEq. Deeper step-out drilling in hole CU-25-39 encountered comparable broad mineralization, returning 15.7 metres grading 193 g/t AgEq and 11.0 metres grading 174 g/t AgEq. This transition from a wide structure to a swarm of wide, parallel zones, spaced favorably at around 10 metres apart, creates a compelling case for high-productivity bulk mining methods distinct from the narrow-vein operations historically seen at Cusi.All of the assays reported in this news release were received past the cut-off date for inclusion in the upcoming Mineral Resource Estimate (\"MRE\") update scheduled for release in December. These holes and the remainder of 2025 drilling will be included in a subsequent MRE update in 2026.Mark Ayranto, CEO of Silverco, commented:\"These results represent a potential paradigm shift for the Cusi project. We are moving beyond isolated intercepts to define a corridor of parallel, high-grade veins with widths upwards of five times the district's historical average. T...
