Silverco Mining intersects 1,712 g/t AgEq over 1.4 m at Cusi

Vancouver, British Columbia--(Newsfile Corp. - June 16, 2026) - Silverco Mining Ltd. (TSXV: SICO) ("Silverco" or the "Company") is pleased to report initial underground assay results from its 100%-owned Cusi Property ("Cusi") in Chihuahua, Mexico. These results are part of the Company's 2026 30,000 metre diamond drill program that is focused on infill, expansion, and exploration at high potential targets across the property. Initial underground drilling at Promontorio, the first of three planned mining zones at Cusi, has been focused on infilling areas that are planned for mining in the first year of operations.

These areas have been identified as highly prospective but required additional drilling to be included in the resource and mine plan. Mark Ayranto, CEO of Silverco, commented : "We are encouraged by the initial results from our 2026 Cusi drill program which have identified additional mineralization within the footprint of the first year of the Preliminary Economic Assessment ("PEA") 1  mine plan. With grades and widths consistent with our resource, these results highlight the opportunity to lower initial underground development, bring more tonnage forward and enhance project economics from the US$312 million after-tax NPV outlined in the PEA at silver prices in line with current levels 2 .

With dewatering and underground rehabilitation complete in Q1 2026, this is our first underground drilling at Promontorio, and the results reinforce our confidence in the vein system as we move toward a restart in H2 2026, with mobilization of underground contractors and commencement of development planned in the coming weeks." The initial results from the 2026 Cusi exploration program are from the Promontorio East veins, an area that boasts exceptional undiluted high-grade material with Measured and Indicated Resource grades of 295 g/t AgEq and Inferred Re
