AbraSilver Files Definitive Feasibility Study Technical Report & Provides Heap Leach PEA Update

AbraSilver Files Definitive Feasibility Study Technical Report & Provides Heap Leach PEA Update

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).

As previously announced on June 22, 2026, the DFS outlines a robust base-case development plan for Diablillos based on a conventional open-pit mining operation and a 9,000 tonne-per-day processing facility. At base case metal prices of $50.00/oz silver and $3,650/oz gold, the DFS delivers 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 period. There are no material differences in the Report from the results disclosed in the Company's June 22, 2026 news release.

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."
