[{"type":"text","content":"Silverco Announces Updated MRE for Cusi: 41 Moz AgEq M&I and 32 Moz AgEq InferredVancouver, British Columbia--(Newsfile Corp. - December 9, 2025) - Silverco Mining Ltd. (TSXV: SICO) (\"Silverco\" or the \"Company\") is pleased to announce a validated and updated Mineral Resource Estimate (\"MRE\") for its 100%-owned Cusi Project (\"Cusi\"), located approximately 90 kilometres northwest of First Majestic's Los Gatos Mine in Chihuahua, Mexico. The Updated Mineral Resource Estimate was completed by Ben Eggers MAIG, P.Geo., and Allan Armitage, Ph.D., P.Geo., of SGS Geological Services.Highlights of the 2025 Cusi Mineral Resource Estimate:Substantial High-Grade Silver Inventory:Measured & Indicated (\"M&I\") Resources: 4.89 million tonnes grading 262 g/t silver equivalent (\"AgEq\") containing 41.2 million ounces AgEq.Inferred Resources: 4.07 million tonnes grading 243 g/t AgEq containing 31.8 million ounces AgEq.San Miguel Growth: The San Miguel Vein System has emerged as a significant growth driver, contributing 10.8 Moz AgEq (Indicated) and 16.2 Moz AgEq (Inferred) to the global resource, validating the Company's focus on this new bulk-tonnage potential zone. Improved Geological Confidence: The updated model utilizes a tighter search radius for Inferred resources (reduced from 200m to 100m) and increased cut-off grades (increased from 95 g/t AgEq to 120 g/t AgEq), resulting in a more conservative and robust estimate focused on profitable ounces.Silver Primary Deposit: 86% of the value of the Updated Mineral Resource Estimate is comprised of silver.Comparison to historical 2020 MRE:The historical 2020 MRE hosted Measured & Indicated resources of 5.4Mt grading 215 g/t AgEq containing 37.0 Moz AgEq and Inferred resources of 4.9Mt grading 183 g/t AgEq containing 28.8 Moz AgEq. Since the historical 2020 MRE, approximately 0.81Mt of diluted resources grading 182 g/t AgEq containing 4.8 Moz AgEq were depleted through mining. Additionally, the impact of reducing the inferred search radius from 200m to 100m, resulted in a reduction of inferred resources of approximately 2.1 Mt containing 10.1 Moz AgEq. Accounting for these impacts, the 2025 updated MRE results in the following highlights:28% increase in M&I resources, net of depletion, from 32.2 to 41.2 Moz AgEq22% increase in M&I grade, from 215 to 262 g/t Ag...
