AbraSilver (OTCQX: ABBRF) announced assay results from five Phase V drill holes at its wholly‑owned Diablillos project (Oculto East) on October 28, 2025. Highlights include a high‑grade intercept of 8.5 m at 13.81 g/t Au in DDH‑25‑077 and a very broad zone of 180 m at 0.65 g/t Au in DDH‑25‑076. Multiple other oxide intersections were reported, including 31.0 m at 0.59 g/t Au and 73.0 m at 0.55 g/t Au. Assays are uncut and undiluted; widths reported are drilled widths and true widths are unknown. Additional deeper assay results are pending before year‑end.
AbraSilver Resource Corp. (OTCQX: ABBRF) has announced significant drill results from its Phase V exploration program at the Diablillos project in Argentina. The drilling campaign revealed substantial mineralization in two key areas: Oculto East yielded 140 meters at 0.57 g/t gold, while JAC returned 32 meters at 100 g/t silver.
Notable intercepts at Oculto East include a bonanza grade of 108.9 g/t gold over 1.0 meter and multiple broad zones of continuous gold mineralization. At JAC, drilling confirmed strong near-surface silver mineralization, including high-grade zones of up to 400 g/t silver over 2.0 meters.
The results demonstrate significant potential for expanding both gold and silver resources beyond the current mineral resource conceptual open pit, with mineralization remaining open in multiple directions.

AbraSilver Resource Corp. (OTCQX: ABBRF) has announced significant drill results from its Phase V exploration program at the Diablillos project in Argentina. The company reported notable gold intercepts at Oculto East, including 60 meters at 1.05 g/t gold (including 17m at 2.83 g/t gold) in hole DDH 25-060A, 16 meters at 1.74 g/t gold in hole DDH 25-067, and 21 meters at 1.51 g/t gold in hole DDH 25-068.
The drilling program has successfully extended the gold mineralization zone 200 meters east of the current open pit boundary, demonstrating strong potential for mineral resource expansion. The company is currently operating with three active rigs and plans to commence drilling at the nearby Cerro Blanco porphyry target to test a promising copper-gold system.
AbraSilver Resource Corp. (OTCQX: ABBRF) has announced a substantial increase in Mineral Resources at its wholly-owned Diablillos property in Argentina. The updated estimate shows total Measured & Indicated resources of 104 million tonnes, containing 199 million ounces of silver and 1.72 million ounces of gold (350 million ounces silver-equivalent).
The resource update includes a 25% increase in contained silver to 186 Moz and a 14% increase in contained gold to 1.55 Moz in the tank leach category. Additionally, a maiden heap leach resource adds 31 million tonnes of lower-grade material containing 13 Moz silver and 162,000 oz gold.
The growth was primarily driven by significant extensions at the JAC deposit, where tonnage increased by 148%, and the Oculto deposit, which saw a 23% increase in tonnage. The company expects further resource expansion from its ongoing Phase V drill program, with another update anticipated in H1/2026.
