Silverco Files Updated Mineral Resource Report on the Cusi Project

Executive Summary

• Silverco Mining Ltd. filed an independent NI 43‑101 technical report dated January 14 2026 (effective October 20 2025) presenting the updated underground mineral resource estimate for the Cusi Ag‑Au‑Pb‑Zn Project in Chihuahua, Mexico.
• Combined Measured & Indicated resources total 4.89 Mt at 206 g/t Ag, 0.15 g/t Au, 0.73 % Pb, and 0.86 % Zn (≈ 262 g/t AgEq); Inferred resources add another 4.07 Mt at 172 g/t Ag, 0.17 g/t Au, 0.89 % Pb, and 1.20 % Zn (≈ 243 g/t AgEq).
• The estimate is based on a validated database of 2,052 drillholes (360,237 m) and 21,522 channels (48,786 m), modeled with 63 three‑dimensional vein models and reviewed by independent qualified persons.

Key Details

• Measured Resources: 0.69 Mt @ 277 g/t Ag, 0.08 g/t Au, 0.37 % Pb, 0.42 % Zn (≈ 6,114 koz Ag, 1.8 koz Au, 5.6 Mlb Pb, 6.3 Mlb Zn).
• Indicated Resources: 4.21 Mt @ 195 g/t Ag, 0.16 g/t Au, 0.78 % Pb, 0.93 % Zn (≈ 26,330 koz Ag, 22.2 koz Au, 72.7 Mlb Pb, 86.5 Mlb Zn).
• Inferred Resources: 4.07 Mt @ 172 g/t Ag, 0.17 g/t Au, 0.89 % Pb, 1.20 % Zn (≈ 22,479 koz Ag, 22.2 koz Au, 79.5 Mlb Pb, 107.5 Mlb Zn).
• Total AgEq: Measured + Indicated = 41,157 koz AgEq; Inferred = 31,753 koz AgEq.
• Database: 2,052 surface/underground drillholes (360,237 m) + 21,522 channels (48,786 m); 105,585 assay intervals (119,756 m) and 71,605 assay intervals (48,783 m) for channel data.
• Modeling: 63 three‑dimensional resource models; 1.5 m capped composites; inverse distance squared interpolation; density of 2.75 g/cm³ applied uniformly.
• Cut‑off Grade: Base case cut‑off of 120 g/t AgEq using metal price assumptions (Ag $30/oz, Au $2,400/oz, Pb $1/lb, Zn $1.35/lb) and recovery rates (Ag 90 %, Au 50 %, Pb 90 %, Zn 60 %).
• Cost Assumptions: Mining cost US$60/t rock; processing & G&A cost US$35/t mineralized material.
• Qualified Persons: Ben Eggers, MAIG, P.Geo., SGS Geological Services (author); peer‑review by Allan Armitage, Ph.D., P.Geo.; technical disclosure approved by Nico Harvey, P.Eng., VP Project Development (company QP).
• No material differences from the December 9 2025 release; no production decision made yet—restart contingent on technical, financial and permitting milestones.
