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: Alberto Orozco, CEO of Capitan Silver, commented: "Our 2026 drilling program continues to deliver robust, high-grade results at the Cruz de Plata project. Drilling continues to build on our previous exploration success, extending mineralization further down-dip, where we are seeing both mineralized widths and grades improving. "We are also encountering new zones of mineralization further at depth, which speak to the strong vertical continuity and deep-rooted scale potential of this project. We expect further drilling will continue to confirm our current geological thesis and structural interpretations, as we look to extend mineralization further."

Drill hole 26-ERDD-10 was drilled to test the down-dip projection and expand the Jesus Maria high-grade zone. Drill hole 26-ERDD-10, drilled on the same section as previously reported drill hole 26-ERRC-48 (see Capitan news release dated April 1, 2026), intersected strong, broad, high-grade silver mineralization, returning 1,071.1 g/t AgEq over 2.0m within 884.3 g/t AgEq over 3.0m, all within a wider interval of 15.8m of 250.1 g/t AgEq. Drill hole 26-ERDD-10 extended mineralization from drill hole 26-ERRC-48 by 50m down-dip, with mineralization remaining open at depth (see Figures 2 and 3).
