Capitan Silver intercepts 1,071 g/t Ag eq. over 2.0 m at Cruz De Plata

Capitan Silver Intersects High-Grade Mineralization in Multiple Drill Holes Vancouver, British Columbia--(Newsfile Corp. - June 15, 2026) - Capitan Silver Corp. (TSXV: CAPT) (OTCQX: CAPTF) ("Capitan" or the "Company") , is pleased to report additional results from its 60,000-metre drill program at its Cruz de Plata silver-gold project, located in Durango, Mexico. The Company is reporting assay results from eight (8) drill holes. Highlights: High-grade mineralization at the Jesus Maria Silver Trend continues to expand down-dip, showing improving widths and grades at depth Drill hole 26-ERDD-10 intersected a broad zone of mineralization, returning 1,071.1 g/t AgEq over 2.0m, within a wider interval of 15.8m of 250.1 g/t AgEq , extending high-grade mineralization 50m down-dip Drilling along the Jesus Maria Silver Trend (east and west of the Peñoles Fault) shows strong vertical continuity; silver mineralization extending down-dip in multiple new drill holes Drill hole 26-ERDD-01 intersected 394.4 g/t AgEq over 1.7m in the upper zone and 620.3 g/t AgEq over 2m within a wider interval of 7.9m of 182.6 g/t AgEq in the lower zone Drill hole 26-SRRC-12 intersected 280.5 g/t AgEq over 6.1m, within a broader zone of 16.8m of 167.2 g/t AgEq, extending mineralization 90m down-dip Capitan has confirmed drilled continuity over 2.5 km of strike with an average depth of 250m, at the Jesus Maria Main Vein; one of several silver mineralized veins that are part of the Jesus Maria Silver Trend.

To date over 21 km of cumulative mineralized vein structures have been identified at the Jesus Maria Silver Trend through surface mapping and sampling programs Upcoming Catalysts: Assays pending for 54 drill holes: 29 core and 25 RC holes, with more arriving weekly 4 rigs actively drilling: 3 diamond (core) drill rigs and
