AbraSilver intersects broad near-surface gold zones at Cerro Viejo, Diablillos

Shallow Oxide-Hosted Gold Confirmed 4 km North of Oculto; Copper Intersected at Depth

Toronto, Ontario--(Newsfile Corp. - September 2, 2026) - AbraSilver Resource Corp. (TSX: ABRA) (OTCQX: ABBRF) ("AbraSilver" or the "Company") is pleased to report new assay results from five holes completed at the Cerro Viejo target as part of the ongoing Phase VI exploration drill program at its wholly-owned Diablillos project in Argentina (the "Project").

Cerro Viejo is located approximately 4 km north of the Oculto deposit, where surface channel sampling and earlier reconnaissance drilling identified gold mineralization associated with extensive east-west trending silicified structures extending for approximately 1.5 km. Initial reconnaissance drilling at Cerro Viejo conducted in 2024 returned 36.0 metres ("m") grading 1.91 g/t gold from a downhole depth of only 87 m in hole DDH 24-056, including 5.0 m grading 7.22 g/t gold (see the Company's news release dated January 27, 2025 ). Follow-up drilling has now confirmed broad zones of shallow, oxide-hosted gold mineralization beginning close to surface, together with copper mineralization in sulphides at depth.

These results further highlight the exploration potential of the Diablillos property beyond the Mineral Resources and Mineral Reserves that underpin the recently completed Definitive Feasibility Study ("DFS").

Highlight Drill Results: Widths are reported as drilled; true widths are not yet known.

DDH 26-037: 27.0 m of 0.58 g/t gold and 4.6 g/t silver from a downhole depth of only 23 metres, within the oxide zone

DDH 26-043: 7.0 m of 0.53% copper from a downhole depth of 97 m , confirming sulphide copper mineralization beneath the gold-bearing oxide zone

DDH 26-047: 32.0 m of 0.29 g/t gold and 2.8 g/t silver from a downhole depth of only 9 m , followed by 14.0 m of 1.50 g/t gold and 6.2 g/t silver fr
