AbraSilver Extends Gold Mineralization at Oculto East with Broad Step-Out Intercept

Latest Hole Returns 42 m at 0.68 g/t Gold Including 7 m at 1.67 g/t Gold

Toronto – July 15, 2025: AbraSilver Resource Corp. (TSX: ABRA; OTCQX: ABBRF) (“AbraSilver” or the “Company”) is pleased to announce new drill results from its ongoing Phase V exploration program at its wholly-owned Diablillos project in Argentina (the “Project”).

Step-out hole DDH 25-062, intersected a continuous 42.0 metre (“m”) interval grading 0.68 g/t gold and 15 g/t silver from 248 m down-hole, including a higher-grade core of 7.0 m at 1.67 g/t gold and 17 g/t silver.  This hole was drilled at Oculto East, beyond the eastern edge of the current conceptual open pit, confirming the extension of mineralization into a previously underexplored area.

This interval is located along the same mineralized trend and approximately 60 m from the high-grade gold intercept, previously announced in hole DDH-25-024 (see Figure 3). These results underscore the potential for significant Mineral Resource expansion at Oculto East.  Follow-up drilling is underway, with three drill rigs now focused on delineating the size and continuity of this promising zone.

John Miniotis, President and CEO, commented, “These results continue to confirm that Diablillos still has significant room for further growth, as we continue to determine the strike direction of the high-grade gold zone at Oculto East.  With three rigs actively drilling this target area, we anticipate steady exploration news flow in the coming weeks and months ahead.”

Dave O’Connor, Chief Geologist, commented, “Hole 25-062 confirms that a broad mineralized zone extends well beyond the current conceptual open pit limits of the Oculto deposit.  Our team is now focused on systematically targeting the most prospective areas of the eastern extension to define the full scale of the high-grade mineralized system.”

AbraSilver Substantially Increases Total Diablillos Mineral Resources to 199 Million Ounces Contained Silver and 1.7 Million Ounces Contained Gold (350 Moz AgEq) in M&I
Updated MRE Highlights Significant Growth Primarily at Oculto & JAC, Plus Maiden Heap Leach Resource

Toronto - July 29, 2025: AbraSilver Resource Corp. (TSX:ABRA; OTCQX: ABBRF) ("AbraSilver" or the “Company”) is pleased to announce a substantial increase to the Mineral Resource estimate (“MRE”) on the Company’s wholly owned Diablillos property in Argentina (“Diablillos” or the “Project”).

The updated MRE now totals 104 million tonnes (“Mt”) of ore, containing approximately 199 million ounces (“Moz”) of silver and 1.72 Moz of gold (350 Moz silver-equivalent “AgEq”) in the Measured & Indicated (“M&I”) category.   This total includes a maiden heap leach Mineral Resource estimate and reflects significant increases across five deposits (Oculto, JAC, Fantasma, Laderas and Sombra) located at Diablillos

Key Highlights of the Updated MRE (Combined Tank and Heap Leach):

   Total M&I Mineral Resources (tank and heap leach) now stand at 104 Mt grading 59 g/t Ag and 0.51 g/t Au, containing 199 Moz Ag and 1.72 Moz Au (350 Moz AgEq).
   Tank leach Mineral Resource estimate totals 73 Mt grading 79 g/t Ag and 0.66 g/t Au, containing 186 Moz Ag and 1.55 Moz Au (327 Moz AgEq).
   Maiden heap leach MRE adds 31 Mt grading 13 g/t Ag and 0.16 g/t Au, containing 13 Moz Ag and 162 koz Au (23 Moz AgEq).
       Based on lower-grade material contained with the constraining Whittle open pit, previously classified as waste, now recognized as potentially recoverable though a low-cost processing route.

Key Changes Compared to Prior MRE (Tank Leach Only):

   25% increase in contained silver in M&I Mineral Resources to 186 Moz Ag from 148 Moz Ag.
   14% increase in contained gold in M&I Mineral Resources to 1.55 Moz Au from 1.36Moz Au.
   27% increase in M&I silver-equivalent ounces to 327 Moz AgEq from 258 Moz AgEq.
       M&I Mineral Resources total 73.1 Mt grading 79 g/t Ag and 0.66 g/t Au (139 g/t AgEq).
       Total Inferred Mineral Resources have increased by 330% and now contain 10 Moz Ag and 0.18 Moz Au (26.6 Moz AgEq).
       The MRE contains only minerals in oxides, located across five Whittle constrained open-pits deposits (Oculto, JAC, Fantasma, Laderas and Sombra).
   The largest uplift in the M&I MRE was driven by the JAC deposit, where tonnage increased by 148% and contained silver increased by 70% (refer to Table 3 for details) due primarily to additional exploration drilling.
   Significant exploration upside remains from the ongoing Phase V drill program, focused mainly at Oculto NE and other potential zones, with another MRE update expected in H1/26.

John Miniotis, President and CEO, commented, “We are very excited to report that M&I Mineral Resources at Diablillos have now grown to nearly 200 Moz of silver and over 1.7 Moz of gold. This substantial increase highlights the exceptional mineral endowment of our Project and our team's continued success in unlocking value through exploration. This updated Mineral Resource estimate will form the basis for the upcoming Definitive Feasibility Study (“DFS”), which remains on track for completion in Q1/2026.”

David O’Connor, Chief Geologist, stated, “The updated MRE demonstrates both the large-scale and high-quality of Diablillos. The JAC zone, in particular, has been a major driver of Mineral Resource growth and is expected to be a key focus of early mining stages, with its high-grade and near-surface location. With significant exploration potential still ahead of us from our ongoing Phase V drill program, we anticipate continued Mineral Resource expansion and additional discoveries across multiple targets.”
