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

On October 28, 2025, AbraSilver announced new drill results from its flagship Diablillos project in Argentina. The highlight was from hole DDH 25-077 at the Oculto East zone, which intersected a high-grade gold interval of 8.5 metres grading 13.81 g/t gold and 14.3 g/t silver.

Other notable results include: - DDH 25-076: 180.0 metres at 0.65 g/t gold and 10.8 g/t silver. - DDH 25-075A: 73.0 metres at 0.55 g/t gold and 3.3 g/t silver.

Management stated that drilling continues to deliver impressive results, expanding the high-grade gold zone at Oculto East well beyond the current conceptual open pit, demonstrating strong growth potential. The company also noted exploration is ongoing at other porphyry targets, with assays pending.

The drill results are positive and continue to confirm the expansion potential of the high-grade gold system at Oculto East. The headline intercept of 8.5 metres at 13.81 g/t gold is excellent and demonstrates the system's ability to produce high-grade results. However, the materiality of this news must be assessed in the context of the company's rapid progression and significant developments over the past year.

• Progression of Exploration: AbraSilver has consistently delivered strong drill results throughout 2025. The story of Oculto East began in February 2025 and was dramatically accelerated by a "best-ever" intercept in May 2025 (31.0m @ 10.0 g/t Au), which caused the stock to gap up significantly. Today's result, while excellent, confirms this pre-existing and now well-understood thesis rather than introducing a new one. It adds to the geological confidence and will contribute positively to the next resource update.

• Context of Recent Financing: The most significant recent event was the closing of a C$46.2 million bought deal financing at C$7.10 per share on October 22, 2025, just six days prior to this news. This financing, which included strategic investors Eric Sprott and Kinross Gold, was a massive vote of confidence that has fully funded the company to accelerate development, secure long-lead time items, and complete its Definitive Feasibility Study (DFS).

• Impact Assessment: The market has already priced in significant exploration success, as evidenced by the C$7.10 financing price. These drill results are precisely the kind of positive news flow required to justify that valuation and support the ongoing de-risking of the project. The results are not a "game-changer" on their own, as the May 2025 intercept and the October financing have already filled that role. Instead, this is a strong, material confirmation that the company is successfully executing its exploration strategy and adding potential ounces, reinforcing the investment case that attracted the recent large-scale funding.

While positive, the news has not pushed the stock back above the C$7.10 financing price, which now acts as a key psychological and technical level. The results are in line with high expectations and are a necessary, but not transformative, piece of news in the company's current advanced stage.

• Project Development: The company released an updated PFS in December 2024 showing a robust after-tax NPV of USD$747M. It has since delivered a significantly larger M&I resource estimate in July 2025 of 350 Moz AgEq. AbraSilver is now focused on completing a Definitive Feasibility Study (DFS), targeted for Q1 2026, and is conducting a 20,000-metre Phase V drill program to further expand resources and test new targets.
• Other Properties: The company also has the La Coipita copper-gold project in Argentina, which is under an earn-in option agreement with major miner Teck Resources.
