AbraSilver drills 748 m of 0.69% Cu, 0.06 g/t Au at La Coipita

Drilling Confirms Continuity of Large-Scale Mineralized System & Delivers New Discovery Toronto, Ontario--(Newsfile Corp. - June 15, 2026) - AbraSilver Resource Corp. (TSX: ABRA) (OTCQX: ABBRF) ("AbraSilver" or the "Company") is pleased to report assay results from the 2026 drill program at the La Coipita copper-gold-molybdenum project ("La Coipita" or the "Project") located in the San Juan Province of Argentina. The drill program is fully funded and operated by a subsidiary of Teck Resources Limited ("Teck") under the terms of the earn-in and joint venture agreement, as per the Company's news release dated January 22, 2024 . The 2026 program comprised 5,248 metres ("m") of diamond drilling across seven holes (DDH-LC26-010 through DDH-LC26-016), designed to test the limits and vertical continuity of known mineralization at the Yaretas target and evaluate new targets generated by the first-ever magnetotelluric ("MT") geophysical survey completed across the property.

Key Highlights Hole DDH-LC26-010 returned the strongest drill intercept recorded to date at La Coipita: 747.5 m grading 0.69% Cu, 0.06 g/t Au and 142 ppm Mo , from 396 m to 1,143.5 m down-hole depth, confirming the presence of a robust and vertically extensive copper-gold-molybdenum system. Including: 108 m at 1.06% Cu, 0.10 g/t Au and 204 ppm Mo, from 396 to 504 m; 184 m at 0.78% Cu, 0.09 g/t Au and 123 ppm Mo, from 604 to 788 m Hole DDH-LC26-011 returned 250.6 m at 0.39% Cu, 0.07 g/t Au and 119 ppm Mo, from 550 to 800.6 m. This hole confirmed continuity of mineralization between previously reported holes DDHC-22-002 and DDH-LC25-006 (see Figures 1 and 2), further strengthening confidence in the scale and continuity of the Yaretas system.

Hole DDH-LC26-012 resulted in a new, shallower discovery at the Yaretas Sur target, located approximately 1.9 km south of the mai
