Silverco Mining Engages SGS to Validate and Update Mineral Resource Estimate at the Cusi Property

Executive Summary

• Silverco Mining engaged SGS Canada to independently validate and update its 2020 historical mineral resource estimate (MRE) for the 100% owned Cusi Property.
• The updated MRE will incorporate up to 11,500 m of recent drilling (6,000 m from 2025 and 5,500 m from 2024), add a new resource area (San Miguel Vein), account for ~900,000 t mining depletion, and tighten inferred‑resource definitions.
• Silverco also contracted Capital Analytica to provide marketing and social‑media services for six months at a fee of $150,000, subject to TSXV approval; the updated MRE is expected later this quarter, positioning the company to apply for Tier 1 issuer status.
