Silverco Mining intercepts 1,100 g/t Ag over 10.3 m at Cusi

Vancouver, British Columbia--(Newsfile Corp. - July 7, 2026) - Silverco Mining Ltd. (TSXV: SICO) ("Silverco" or the "Company") is pleased to report additional underground assay results and initial surface 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. Results included in this release are from underground drilling at Promontorio, the first of three planned mining zones at Cusi.

Drilling in this zone has been focused on infilling highly prospective areas that are planned for mining in the first year of operations which required additional drilling to be included in the resource and mine plan. Mark Ayranto, CEO of Silverco, commented : "Our second set of results from the 2026 Cusi drill program continue to identify additional mineralization within the footprint of the first year of the Preliminary Economic Assessment ("PEA") 1  mine plan. Our headline hole, UGCU26-08, intersected grades more than three times the average resource grade at Promontorio.

With this intersection sitting only approximately 25 metres below existing development, we have again delivered the kind of result that can enhance Cusi's operating profile early in the mine life. The elevated gold grades in this hole also suggest we remain high in the epithermal system at Promontorio, highlighting the potential for significant untested vertical extent at depth. Exploration at Cusi will test more of these targets through the remainder of 2026 to support the planned restart of production in Q4 2026, as underground mining contractors ramp up development rates through Q3 2026." These second set of drill results from the 2026 program are from the Promontorio East veins, an area that boasts exception
