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

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.

The latest drill holes continue to expand the gold-bearing zone at Oculto East, intersecting consistent mineralization well beyond the current Mineral Resource outline. These results reinforce the potential for continued growth and highlight Oculto East as a key focus area in the current exploration program.

• DDH 25-060A: 60.0 metres (“m”) grading 1.05 g/t gold from 230 metres, including:
  • 17.0 m at 2.83 g/t gold
  • 4.0 m at 6.68 g/t gold
• DDH 25-067: 16.0 m grading 1.74 g/t gold & 17.3 g/t silver from 245 metres
• DDH 25-068: 21.0 m grading 1.51 g/t gold & 49.5 g/t silver from 188 metres, and
  • 64.0 m grading 0.54 g/t gold & 19.8 g/t silver from 314 metres,

AbraSilver Drilling at Diablillos Intersects 8.5 Metres at 13.81 g/t Gold at Oculto East

Separate Hole Intersects Broad Zone of 180 m Grading 0.65 g/t Gold

Toronto, Ontario--(Newsfile Corp. - October 28, 2025) - AbraSilver Resource Corp. (ABRA:CA) (OTCQX: ABBRF) ("AbraSilver" or the "Company") is pleased to announce new assay results from five drill holes from the ongoing Phase V exploration program at its wholly-owned Diablillos project in Argentina (the "Project"). These results continue to expand oxide-hosted gold mineralization to the east of the Oculto deposit, extending the high-grade gold zone and highlighting the continued strong exploration upside potential across the Diablillos system.

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

At Oculto East, numerous broad zones of gold and silver mineralization were intercepted, including:

DDH 25-073: 10.0 metres ("m") grading 59 g/t silver (from 117 m downhole) & 20.0 m grading 0.66 g/t gold (223 m downhole)

DDH 25-074: 31.0 m grading 0.59 g/t gold (from 255 m)

DDH 25-075A: 73.0 m grading 0.55 g/t gold (from 277 m), including 13.5 m at 0.83 g/t gold & 16.5 m grading 0.75 g/t gold

DDH 25-076: 12 m grading 62 g/t silver (from 128 m downhole) & a very broad, well-mineralized intercept of 180.0 m grading 0.65 g/t gold (from 170 m), including 15.0 m at 1.36 g/t gold

DDH 25-077: A high-grade interval of 13.81 g/t gold over 8.5 m from 317 m, and a separate interval of 44.0 m at 0.65 g/t gold from 368 m

John Miniotis, President and CEO, commented, "Drilling at Oculto East continues to deliver impressive results with wide, high-grade gold intercepts. The continued expansion of this zone well beyond the current conceptual open pit demonstrates the strong growth potential of Diablillos and positions us to continue unlocking significant value through ongoing exploration and development."

AbraSilver Continues to Drill High-Grade Gold at Diablillos, with 36 Metres of 2.32 g/t Gold Intersected at Oculto East

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

Cerro Viejo: Both holes drilled at Cerro Viejo intersected continuous gold mineralization from surface, interpreted to represent the upper levels of a mineralized porphyry system:

DDH 25-050: 128.0 metres ("m") at 0.24 g/t gold from surface

DDH 25-056: 200.0 m grading 0.32 g/t gold from surface, including:

10.0 m at 1.10 g/t (oxides, from 21 m downhole)

11.0 m at 0.33 g/t gold and 0.46% copper (sulphides, from 49 m)

Oculto East: Both holes intersected broad zones of oxide gold mineralization, with DDH 25-078 returning multiple high-grade intervals and DDH 25-081 confirming additional consistent gold zones within the broader mineralized corridor, which drilling continues to expand. Importantly, holes 78 and 81 represent two distinct sub-parallel zones of mineralization at Oculto East, located approximately 500 metres apart, further demonstrating the scale and continuity of this system.

DDH 25-078 returned several high-grade gold intercepts within a ~100-metre-thick mineralized package, including:

25.0 m grading 1.67 g/t gold (from 178 m) including 2.0 m at 11.14 g/t gold;

6.0 m grading 4.64 g/t gold (211 m);

36.0 m grading 2.32 g/t gold (240 m) including 11.0 m grading 3.76 g/t gold

DDH 25-081 also encountered several oxide gold zones, including:

8.0 m grading 0.76 g/t gold (267 m);

10.0 m grading 0.72 g/t gold (341 m);

John Miniotis, President and CEO, commented, "Our drilling continues to deliver excellent results across multiple high-priority targets at Diablillos. At Oculto East, we are consistently intersecting thick zones of high-grade oxide gold mineralization that continue to expand the known mineralized footprint. In parallel, the initial results from Cerro Viejo highlight the potential for a robust gold-copper porphyry system. Together, these results underscore the strong growth potential across the broader Diablillos project."

RIGI Application and Definitive Feasibility Study ("DFS")

The Company has now completed all required work for the application under Argentina's Large Investment Incentive Regime ("RIGI"), which is expected to be formally submitted in the near-term. RIGI is a new federal investment framework designed to attract and accelerate major development projects by providing long-term fiscal stability and a competitive suite of tax, customs, and foreign-exchange benefits.

The design and engineering work for the DFS is nearing completion and planning for early works activities is advancing on schedule. Metallurgical test work and all site investigation activities are completed, with final optimization parameters established for the updated open pit mine plan. The technical team is preparing for third party reviews at the 80% completion milestone over the coming weeks. The DFS remains on track for completion in H1 2026, at which time the project will be ready to advance with early works activities and a final investment decision.
