According to the company, the DFS base case, using open-pit mining and a 9,000 tonne-per-day plant, outlines an after-tax NPV5% of US$3.0 billion (C$4.2 billion), an after-tax IRR of 41.9% and a 1.7-year payback at $50/oz silver and $3,650/oz gold, consistent with June 22, 2026 disclosures. AbraSilver also reports heap leach metallurgical testwork on lower-grade material delivered gold recoveries above prior assumptions, prompting an updated Mineral Resource Estimate and targeting completion of the heap leach PEA in Q4 2026.

Toronto, Ontario--(Newsfile Corp. - July 21, 2026) - AbraSilver Resource Corp. (TSX: ABRA) (OTCQX: ABBRF) ("AbraSilver" or the "Company") is pleased to announce that it has filed a National Instrument 43-101 - Standards of Disclosure for Mineral Projects compliant Technical Report for its Definitive Feasibility Study ("DFS" or the "Report") on its wholly-owned Diablillos project in Argentina ("Diablillos").
The Report titled "NI 43-101 Technical Report, Definitive Feasibility Study for the Diablillos Ag-Au Project" is dated July 20, 2026 and has an effective date of June 19, 2026. The Report can be found under the Company's profile on SEDAR+ (www.sedarplus.ca) and on the Company's website (www.abrasilver.com).

Heap Leach PEA Update
The Company also provides the following update on the Preliminary Economic Assessment (the "PEA") evaluating a potential supplementary heap leach operation at Diablillos. The PEA is now expected to be completed during the fourth quarter of 2026.
The most recent phase of metallurgical testwork on lower-grade mineralization intended for the proposed heap leach operation delivered results that exceeded management's expectations, demonstrating significantly improved gold recoveries relative to previous assumptions.
In light of these encouraging findings, the Company has elected to complete an updated Mineral Resource Estimate incorporating additional mineralization considered suitable for heap leach processing prior to finalizing the PEA. The PEA will subsequently be completed on the basis of this updated resource, providing a more comprehensive assessment of the long-term value creation opportunity associated with a potential additional heap leach operation at Diablillos.
John Miniotis, President and CEO of AbraSilver, commented, "The better-than-expected metallurgical results from our heap leach testwork program reinforce the significant upside potential that exists beyond the DFS base case. We look forward to publishing a more comprehensive Heap Leach PEA later this year that incorporates an updated Mineral Resource Estimate and more fully reflects the long-term potential of the heap leach opportunity at Diablillos."
